Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0874331630 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Type: Must be receptacle with outer shroud contacts
• Position Count: Exactly 31 positions
• Pitch Specification: 0.039" (1.00mm) contact spacing
• Row Configuration: 2-row arrangement
• Mounting Technology: Surface mount capability
• Contact Material: Gold plating
• Mechanical Features: Board guide requirement
• Environmental Rating: MSL 1 classification

The Amphenol ICC (FCI) part number 91930-21131LF meets all these criteria and is qualified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 91930-21131LF is the qualified substitute for the obsolete Molex 0874331630. Selection of this alternative is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Regulatory Compliance: The Amphenol ICC part is RoHS compliant, whereas the original Molex part is non-compliant. This compliance status is significant for applications subject to RoHS regulations.

Mechanical Compatibility: Both parts share identical pitch (0.039"/1.00mm), position count (31), row configuration (2), and connector type specifications. Height above board measurements are equivalent (0.130" vs. 0.129"), and the substitute provides expanded mated stacking height options that encompass the original part's specifications.

Electrical Equivalence: Contact finish specifications are compatible, with the substitute offering gold or gold GXT™ options. Both parts maintain MSL 1 classification.

Additional Features: The substitute incorporates solder retention in addition to board guide features, providing enhanced manufacturing robustness.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 91930-21131LF be used as a direct replacement for the Molex 0874331630?

A: Yes. Both parts share identical electrical and mechanical specifications for the critical parameters: 31 positions, 0.039" (1.00mm) pitch, 2-row configuration, surface mount technology, and gold contact finish. Height above board measurements are equivalent within tolerance.

Q: What is the significance of the RoHS compliance difference?

A: The substitute part is RoHS compliant while the original is non-compliant. For applications subject to RoHS regulations, the Amphenol ICC part is the appropriate selection. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: Are the mated stacking height options compatible?

A: Yes. The original Molex part specifies 5mm and 7mm stacking heights. The Amphenol ICC substitute provides these heights plus additional options (4.15mm, 4.5mm, 5.5mm, 6mm, 7.52mm), ensuring compatibility with existing mating connector specifications.

Q: What is the difference between standard gold and gold GXT™ contact finish?

A: Both finishes are gold-based contact materials. The GXT™ designation indicates an enhanced gold plating variant offered by Amphenol ICC. For applications requiring standard gold plating, the non-GXT™ option is available.

Q: Does the addition of solder retention features affect compatibility?

A: No. Solder retention is an additional manufacturing feature that enhances board-level assembly robustness. It does not affect electrical or mechanical compatibility with mating connectors designed for the original part.

Q: What is the packaging difference?

A: The original Molex part packaging is not specified. The Amphenol ICC substitute is supplied in tube packaging, which is standard for surface mount connectors and does not affect component functionality.
