Engineering Selection Recommendations

All substitute parts listed maintain active product status and comply with ROHS3 and REACH requirements, matching the compliance profile of the Molex 0702804402. Selection among substitute options depends on specific application requirements:

Contact finish selection: PEC04 series parts feature tin mating finish, matching the original Molex part specification. PBC04 series parts feature gold mating finish, providing enhanced corrosion resistance in demanding environments.

Post length variation: Substitute parts are available in four post length configurations (0.120", 0.220", 0.420", 0.520"). Selection must align with PCB thickness and application stack-up requirements. The original Molex part specifies 0.148" post length; PEC04DFAN and PBC04DFAN provide the closest match at 0.120".

Insulation material: Substitute parts use polybutylene terephthalate (PBT) insulation versus the original LCP glass-filled material. Both materials meet UL94 V-0 flammability requirements.

Contact material: Substitute parts use phosphor bronze versus the original copper material, with specified operating temperature range of -65°C to 125°C and 3A current rating.

Frequently Asked Questions (FAQ)

Q: Can PEC04DFAN be used as a direct replacement for Molex 0702804402?

A: PEC04DFAN is functionally compatible for applications requiring 8-position 2.54mm pitch through-hole headers with solder termination. The primary difference is post length (0.120" versus 0.148"), which must be verified against PCB thickness specifications. Both parts meet UL94 V-0 and ROHS3 compliance requirements.

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

A: The primary distinction is contact finish at the mating interface. PBC04 series parts feature gold mating finish, while PEC04 series parts feature tin mating finish. Both series use phosphor bronze contact material and PBT insulation. Selection depends on application requirements for corrosion resistance and contact wear characteristics.

Q: How do post length variations affect compatibility?

A: Post length determines the depth of solder connection into the PCB. The original Molex part specifies 0.148" post length. Substitute parts range from 0.120" to 0.520". Selection must account for PCB thickness and any stacked component clearance requirements. Shorter posts (0.120") suit thinner PCBs, while longer posts (0.420", 0.520") accommodate thicker assemblies or stacked configurations.

Q: Are all substitute parts rated for the same current and temperature range?

A: All substitute parts are rated for 3A current and -65°C to 125°C operating temperature. The original Molex part does not specify current or temperature ratings in the provided data. Verify these ratings against your application requirements.

Q: Do substitute parts maintain the same shrouding configuration?

A: Yes, all substitute parts maintain unshrouded configuration matching the original Molex 0702804402, ensuring mechanical compatibility in board-to-board and cable applications.
