Basics
My search for Micro-ISO relays began with some instructions for converting an ST1300 to an electric windshield. It has a picture of the two types of Micro-ISO relays, as well as the rubber "suspension" sleeves intended to isolate the relays from vibration.
There are two common types of relays, SPST (Single Pole, Single Throw) and SPDT (Single Pole, Double Throw). SPST relays can only close a circuit. SPDT relay close one circuit at rest, and a second circuit when active. Effectively, the only difference is an extra output leg on the SPDT relays, so unless you're worried about confusing yourself, you may as well use SPDT relays and ignore the extra output leg when it's unneeded.
Sourcing from Honda
Ron Ayers shows the two-way Micro-ISO relays on their ST1300 cowl microfiche. It's item five, part number 38502-MCS-G00, "RELAY (MICRO ISO 5P)".
For reference, his same relay is available from Cycle-Parts for $6.46. Ron Ayers, by comparison, is $6.15.
A second, four-point relay is available on the ST1300 wire harness microfiche as item eight. Part number 38501-MCS-G00, "RELAY (MICRO ISO 4P)". This is a four point relay, meaning that it can only close a single circuit, rather than switching between two circuits. Since it's the same price, at $6.15, I can't see any reason not to buy the five-point relay!
Manufacturer
The Micro-ISO relays sold by Honda are made by Omron. The five-point relay is Omron part number G8HN-1C4T-RH. The final H indicates "high capacity". The 4T- indicates sealed (unsealed is -2T). -1A indicates SPST ("four-point"), while -1C indicates SPDT ("five-point"). As near as I can tell, the -R indicates a suppression resistor is used (where??).
Omron's GH8N-J Data Sheet has the following specification charts. The relevant information is in bold:
| Part Number | Contact Type | |
| Unsealed | Sealed | |
| G8HN-1A2T-RJ/DJ (DC12V/DC24V) | G8HN-1A4T-RJ/DJ (DC12V/DC24V) | SPST Standard |
| G8HN-1C2T-RJ/DJ (DC12V/DC24V) | G8HN-1C4T-RJ/DJ (DC12V/DC24V) | SPDT Standard |
| G8HN-1A2T-RH/DH (DC12V) | G8HN-1A4T-RH/DH (DC12V) | SPST High capacity |
| G8HN-1C2T-RH/DH (DC12V) | G8HN-1C4T-RH/DH (DC12V) | SPDT High capacity |
| Arrangement | SPST,SPDT | ||
| Contact material | Silver tin oxide (cadmium free) | ||
| Contact voltage drop | Standard | Less than 200 mV at 20A | |
| High capacity | Less than 200 mV at 35A | ||
| Max. Switching Current | Standard | 12VDC | N.O. side: Inrush 100A, Steady 20A N.C. side: Inrush 50A, Steady 10A |
| 24VDC | N.O. side: Inrush 30A, Steady 10A N.C. side: Inrush 15A, Steady 5A | ||
| High capacity | 12VDC | N.O. side : Inrush 120A, Steady 35A N.C. side : Inrush 40A, Steady 20A | |
Incidentally, the G8HR line seems to be a high-capacity standard ISO relay, handling 70 amps. It uses a pinout like a typical Bosch-type relay, except that the input leg is massive.
Alternative Sources for Omron relays
The Mouser catalog, page 1300 lists the G8HN-1C2T-R-DC12 relay for $4.38. However, these are neither sealed (2T-) nor high-capacity (no final H), so don't use these.
Alternative Manufacturers
Bosch
The Airhead BMW group says lists the following for Micro-ISO relays:
BMW: 61 31 1 459 677
Type: 12V; micro-relay
Notes: "Load Shedding" Relay for all 'GS, 'R and 'MYS '91 on (30, 85, 86, 87 w/ 680ohm resistor 85-86)
Bosch: 0 332 017 100*, 0 332 207 100*, 0 332 207 300*, 0 332 207 301*, 0 332 207 310*
Chief Enterprises has an excellent list of Bosch relays. I stole the relevant information and put it here:
| Part number | Voltage | Form | Load current | Suppression | Enclosure |
| 0 332 011 007 | 12 V | SPST | 30 A - 100,000 cycles | Resistor | Standard cover |
| 0 332 017 300 | 12 V | SPST | 20A - 300,000 cycles | Resistor | Standard cover |
| 0 332 017 302 | 12 V | SPST | 20A - 300,000 cycles | Resistor | Standard cover w/bracket |
| 0 332 201 107 | 12 V | SPDT | 30 A - 100,000 cycles | Resistor | Standard cover |
| 0 332 207 307 | 12 V | SPDT | 20A - 300,000 cycles | Resistor | Standard cover |
| 0 332 207 310 | 12 V | SPDT | 20A - 300,000 cycles | Resistor | Standard cover w/bracket |
Waytek Wire lists:
| Picture | Bosch p/n | Waytek p/n | Price | Minimum Qty |
|
0 332 017 302 | 75202 | $3.97 | 2 |
|
0 332 207 307 | 75213 | $2.99 | 2 |
|
0 332 011 007 | 75230 | $2.86 | 2 |
|
0 332 201 107 | 75231 | $2.99 | 2 |
Hella
According to this Hella page the 87416 is a 10/20 amp SPDT relay with resistor. It lists the new part number as H41524021.
Tyco Electronics
Tyco Electronics also produces Micro ISO relays. Their product data sheet is available here. They list two useful part numbers:
| Relay Part No | Tyco order No | Contact arrangement | Contact material | Enclosure | Terminals |
| VFMA-21F41-S01 | 0-1432503-1 | 1 Form A (SPST) | AgSnO2 | Dust cover, Sealed | Quick connect |
| VFMA-25F41-S01 | 0-1432506-1 | 1 Form C (SPDT) | AgSnO2 | Dust cover, Sealed | Quick connect |
It appears that "Form A" means SPST (can only switch on or off), while "Form C" means SPDT (can switch between two contacts). According to this page the S01 indicates a resistor (680Ω) in parallel with the coil, which presumably is analogous the -R in the Omron part numbers.
P&B
P&B makes Micro-ISO relays.
Zettler Automotive
Zettler also makes Micro-ISO relays (p/n AZ988). Interestingly, it gives the following cross reference part numbers:
- Aromat: CM
- Bosch: 0 332
- Hella: 87416
- Omron: G8H
- Song Chuan: 871
- Tyco: VFM
Panasonic
Panasonic's Micro-ISO relay datasheet is available here.
Digi-Key lists Panasonic Micro-ISO relays. They're significantly cheaper than other relays I've found, but with zero on-hand at Digi-Key and a minimum order across-the-board of 50, this is probably not a suitable solution:
| Digi-Key p/n | Mfr p/n | Description | Vendor | Unit Price | Min Qty |
| ACV11012-ND | ACV11012 | RELAY AUTO 12VDC MICRO ISO PLUG | Panasonic Electric Works | 2.98000 | 50 |
| ACV31012-ND | ACV31012 | RELAY AUTO 12VDC MICRO ISO PLUG | Panasonic Electric Works | 2.90000 | 50 |
| ACV31024-ND | ACV31024 | RELAY AUTO 24VDC MICRO ISO PLUG | Panasonic Electric Works | 3.08000 | 50 |
| ACV11024-ND | ACV11024 | RELAY AUTO 24VDC MICRO ISO PLUG | Panasonic Electric Works | 3.14000 | 50 |
Sockets
Chief Enterprises has a catalog page with very nice pictures of Bosch relay sockets, including Micro-ISO sockets:
- Bosch part number 3 334 485 045 with mounting tab.
- Bosch part number 3 334 485 046 without mounting tab.
According to this Waytek page these Micro-ISO sockets require three 30073 (3/16" 20-16GA) and two 31073 (1/4" 14-16GA) female terminal pins.
WayTek sells
- Bosch 3 334 485 045 (Waytek p/n 75290) for $0.65 each, minimum quantity eight.
Electronic Surplus Inc lists the Bosch relay with tab (3 334 485 045) for $5.
