Engineering Selection Recommendations

Primary Equivalent: Molex 0010897081 provides the closest functional match to the 77313-402-08LF. Both parts share identical pitch, position count, row configuration, and termination method. The Molex part is ROHS3 compliant and maintains UL94 V-0 flammability rating. Inventory availability is higher (2770 units). The primary difference is insulation material (LCP glass-filled versus thermoplastic), which does not affect electrical or mechanical compatibility for standard through-hole applications.

Sullins PBC04 Series (Gold-Plated Mating Surface): The PBC04DAAN, PBC04DABN, PBC04DAEN, and PBC04DAHN variants offer gold-plated mating surfaces with phosphor bronze contacts and PBT insulation. These parts maintain the 3A current rating and UL94 V-0 rating. Selection within this series depends on required post length: PBC04DAAN (0.120" post), PBC04DABN (0.230" post), PBC04DAEN (0.520" post), and PBC04DAHN (0.820" post). Operating temperature is -65°C to 125°C. ROHS3 compliant.

Sullins PEC04 Series (Tin-Plated, PBT Insulation): The PEC04DAAN, PEC04DABN, PEC04DACN, PEC04DADN, and PEC04DAEN variants provide tin-plated mating surfaces with phosphor bronze contacts and PBT insulation. These parts maintain the 3A current rating and UL94 V-0 rating. Post length options range from 0.120" (PEC04DAAN) to 0.520" (PEC04DAEN). Operating temperature is -65°C to 125°C. ROHS3 compliant.

Selection Criteria:

For direct replacement without design modification: Molex 0010897081
For gold-plated contact surfaces: Sullins PBC04 series
For tin-plated surfaces with PBT insulation: Sullins PEC04 series
Post length selection depends on PCB stack-up and mating connector depth requirements

All substitute parts are active in production status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010897081 be used as a direct drop-in replacement for the Amphenol ICC 77313-402-08LF?

A: Yes. Both parts share identical mating pitch (2.54mm), position count (8), row configuration (2 rows), contact type (male pin), mounting method (through-hole), and termination (solder). The primary difference is insulation material composition, which does not affect mechanical or electrical compatibility in standard applications.

Q: What is the difference between the Sullins PBC04 and PEC04 series?

A: The primary difference is contact finish. PBC04 series features gold-plated mating surfaces, while PEC04 series features tin-plated mating surfaces. Both series use phosphor bronze contacts and PBT insulation. Post length varies within each series to accommodate different PCB stack-up requirements.

Q: How do I select the correct post length for my application?

A: Post length determines how far the solder tail extends below the PCB. Selection depends on your PCB thickness and any components or clearances on the underside. Available post lengths range from 0.107" to 0.820". Consult your PCB design specifications and mating connector requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Amphenol ICC 77313-402-08LF is RoHS Compliant. All identified substitute parts are ROHS3 Compliant, which meets or exceeds RoHS requirements.

Q: What is the operating temperature range for substitute parts?

A: The Amphenol ICC 77313-402-08LF operates from -65°C to 130°C. Molex 0010897081 does not specify operating temperature. Sullins PBC04 and PEC04 series operate from -65°C to 125°C, which covers most industrial and commercial applications within the lower bound of the original part.

Q: Can I mix and match contact finishes in the same assembly?

A: Contact finish selection should be consistent within a mating pair to ensure reliable electrical contact. Mixing tin-plated and gold-plated contacts in the same connector interface is not recommended.

Q: What packaging formats are available?

A: The Amphenol ICC 77313-402-08LF is supplied in bag packaging. Molex 0010897081 is supplied in bulk packaging. Sullins PBC04 and PEC04 series are supplied in bulk packaging. Packaging format does not affect component functionality.

Q: Are these parts suitable for automotive applications?

A: The Molex 0010897081 lists automotive applications. The Amphenol ICC 77313-402-08LF and Sullins parts do not specify automotive applications in the provided data. Confirm application suitability with your design requirements and supplier documentation.
