2.2mm Automotive Crimp Pins – OEM 8100-1428 / 8230-4552 | 50pcs Male & Female | Sumitomo / Honda / Toyota

The OEM 8100-1428 / 8230-4552 are 2.2mm pitch automotive crimp pins used in Honda and Toyota connector systems. The 8100-series prefix identifies these as Sumitomo Electric terminals; the 8230-series is Toyota’s OEM cross-reference for the same terminal in Toyota’s parts catalog. The 2.2mm pitch accommodates medium-gauge wire (typically 18–22 AWG / 0.5–1.0mm²) for sensor signal, actuator control, and moderate-current circuits. Sold in 50-piece packs for Male and Female variants.

Sumitomo Electric – The OEM Behind Honda and Toyota Harnesses

Sumitomo Electric is one of the world’s largest automotive wire harness manufacturers, supplying OEM harness systems to Honda, Toyota, Nissan, and other major automakers. The 8100-series terminal family is Sumitomo’s standard 2.2mm pitch contact system, used across Honda and Toyota engine management, body electrical, and chassis harnesses. Toyota assigns its own part numbers (8230-series) to the same Sumitomo terminals in Toyota’s parts catalog, which is why both part numbers refer to the same physical terminal.

Part Number Cross-Reference

• 8100-1428: Sumitomo Electric part number — Female 2.2mm pitch contact
• 8230-4552: Toyota OEM cross-reference — Male 2.2mm pitch contact (Toyota parts catalog)
• Honda equivalent: Honda assigns its own part numbers to the same Sumitomo terminal family; cross-reference via Honda’s parts catalog using your vehicle’s VIN

Crimping Requirements

• Strip wire insulation to 4–5mm for 2.2mm pitch contacts
• Use a ratchet crimp tool rated for Sumitomo 2.2mm pitch contacts (e.g., Sumitomo 182-630-0 or equivalent)
• Insert terminal into connector housing until the locking tab clicks — verify with a gentle pull test
• Apply dielectric grease to the terminal before insertion in high-moisture environments

Frequently Asked Questions

Q: What is the difference between 8100-1428 (Female) and 8230-4552 (Male)?
A: 8100-1428 is the Sumitomo part number for the female contact (socket — receives the male pin). 8230-4552 is Toyota’s cross-reference for the male contact (pin — inserts into the female socket). They are the mating pair for the same 2.2mm pitch connector system.

Q: Can I use these terminals in non-Honda/Toyota applications?
A: Yes. The 2.2mm pitch Sumitomo terminal is a standard contact size used in many connector housings beyond Honda and Toyota. Verify the housing’s terminal acceptance specification before ordering.

Q: How many terminals do I need for a full connector repair?
A: Order one terminal per pin that needs replacement. For a full connector re-pin, order the same quantity as the connector’s pin count. The 50-piece pack is suitable for multiple connector repairs or a full harness re-pin.
