Engineering Selection Recommendations

Molex 0395056004 and Molex 0395056504 are direct functional equivalents with active product status and ROHS3 compliance. Both maintain the 8A current rating and 300V voltage specification. The primary distinction is contact mating finish: 0395056004 features tin plating (matching the original), while 0395056504 provides gold plating for enhanced corrosion resistance in demanding environments.

Amphenol Anytek OQ0415500000G offers elevated current capacity at 10A per position, exceeding the original specification. This part is suitable for applications requiring higher current margins while maintaining 300V voltage rating and ROHS3 compliance.

On-Shore Technology OSTOQ041550 maintains core electrical specifications with ROHS3 compliance and tin-plated contacts. This option provides an alternative sourcing path with active product availability.

All substitute parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, ensuring compatibility with the original application requirements.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0395056504 (gold-plated) as a direct replacement for the Phoenix Contact 1937428 (tin-plated)?

A: Yes. Both parts meet the core electrical and mechanical specifications: 4 positions, 4.60mm pitch, vertical through-hole mounting, 8A current rating, and 300V voltage rating. The gold plating on the Molex part provides superior contact reliability in corrosive environments compared to tin plating.

Q: What is the difference between Molex 0395056004 and 0395056504?

A: Both are Eurostyle ESE 39505 series parts with identical electrical and mechanical specifications. The distinction is contact mating finish: 0395056004 uses tin plating, while 0395056504 uses gold plating. Select based on environmental corrosion requirements.

Q: Why does Amphenol Anytek OQ0415500000G have a 10A rating instead of 8A?

A: The OQ0415500000G is rated for 10A per position, exceeding the original 8A specification. This higher rating does not prevent substitution; it indicates the part can safely handle the original 8A requirement with additional capacity margin.

Q: Is the On-Shore Technology OSTOQ041550 compatible with through-hole PCB mounting?

A: The OSTOQ041550 is specified for solder mounting, which is compatible with through-hole PCB assembly processes. Verify mounting method compatibility with your specific PCB design.

Q: Do all substitute parts meet RoHS compliance?

A: Molex 0395056504, Amphenol Anytek OQ0415500000G, and On-Shore Technology OSTOQ041550 are ROHS3 compliant. Molex 0395056004 RoHS status is not specified in available documentation.

Q: What is the contact tail length difference between the Phoenix Contact original and substitutes?

A: The Phoenix Contact 1937428 has a contact tail length of 0.134" (3.40mm), while most substitutes measure 0.138" (4.60mm). This 0.004" difference is within typical PCB design tolerances for through-hole applications.
