Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0876331003 is based on strict alignment of the following critical parameters:

• 30-position receptacle configuration with female sockets and blade sockets
• 0.100" (2.54mm) pitch spacing
• 4-row arrangement
• 24 signal and 6 power contact layout
• Through-hole press-fit termination
• Gold contact finish at 30.0µin (0.76µm) thickness
• Black housing color
• UL94 V-0 flammability rating
• Operating temperature range of -20°C ~ 105°C
• Guide pin feature
• MSL 1 moisture sensitivity level

The Amphenol ICC (FCI) 51750-008LF meets all these parameters and qualifies as a direct substitute. The primary distinction is the connector style designation (Blade Power) and active product status, which provides improved supply chain availability compared to the obsolete Molex part.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51750-008LF is a qualified substitute for the Molex 0876331003 based on electrical and mechanical parameter equivalence. Both connectors meet UL94 V-0 flammability requirements, operate across the identical temperature range, and maintain equivalent contact finish specifications.

The primary advantage of selecting the 51750-008LF is its active product status, which ensures ongoing manufacturing support and supply chain availability. The Molex 0876331003, classified as obsolete, presents supply constraints for new production and field service applications.

Both parts maintain RoHS compliance and MSL 1 moisture sensitivity ratings, supporting deployment in standard industrial and commercial environments without additional handling precautions.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51750-008LF directly replace the Molex 0876331003 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 30-position configuration, 0.100" pitch, 4-row arrangement, press-fit termination, and contact finish thickness. PCB footprints and mating interface requirements are equivalent.

Q: What is the difference between the connector styles listed for each part?

A: The Molex part is designated as EXTreme PowerPlus 87633 series, while the Amphenol ICC part is designated as PwrBlade®. Both designations refer to connector families with identical functional specifications for this 30-position receptacle configuration. The style designation does not affect electrical or mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The Molex 0876331003 is supplied without specified packaging, while the Amphenol ICC 51750-008LF is supplied in trays. Packaging format does not affect connector performance or compatibility.
