Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0874332630 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Receptacle with outer shroud contacts
• Electrical Interface: 51 positions in a 2-row arrangement
• Contact Pitch: 0.039" (1.00mm) spacing
• Mounting Technology: Surface mount with board guide feature
• Contact Material: Gold plating for signal integrity and corrosion resistance
• Physical Envelope: Height above board within compatible range (0.129" to 0.130")
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity level)

The Amphenol ICC (FCI) part 91930-21151LF meets all these substitution criteria. Both connectors share identical position count, pitch, row configuration, and mounting methodology. The substitute part is actively manufactured and RoHS compliant, addressing the obsolescence status of the original Molex component.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 91930-21151LF is the direct functional equivalent for the obsolete Molex 0874332630. Selection criteria are based on the following factors:

Product Status: The Molex part is obsolete, while the Amphenol ICC alternative is actively manufactured. This ensures long-term component availability and supply chain continuity.

Compliance & Certifications: The substitute part is RoHS compliant, addressing regulatory requirements for new designs. Both parts maintain MSL 1 rating and share identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment.

Physical & Electrical Compatibility: Both connectors maintain equivalent pitch (1.00mm), position count (51), row configuration (2), and mounting methodology (surface mount). Height above board measurements are within 0.001" tolerance, ensuring PCB layout compatibility.

Enhanced Features: The Amphenol ICC part includes solder retention in addition to board guide features, providing improved manufacturing robustness during assembly processes.

Inventory & Availability: The substitute part has higher stock levels (1722 units versus 853 units), supporting immediate procurement for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 91930-21151LF directly replace the Molex 0874332630 on existing PCBs?

A: Yes. Both connectors share identical pitch (1.00mm), position count (51), row configuration (2), and mounting type (surface mount). Physical envelope dimensions are equivalent within manufacturing tolerance. No PCB redesign is required.

Q: What is the significance of the contact finish difference (Gold versus Gold, GXT™)?

A: Both finishes are gold-based and provide equivalent electrical performance and corrosion resistance. The GXT™ option on the Amphenol ICC part represents an enhanced contact finish variant. Either finish option is functionally compatible with the original Molex specification.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is mandatory for components used in new designs destined for markets with environmental regulations. The Molex 0874332630 is RoHS non-compliant, making the RoHS-compliant Amphenol ICC alternative necessary for regulatory adherence in current manufacturing environments.

Q: Are the mated stacking heights compatible between the two parts?

A: The Molex part supports 5mm and 7mm stacking heights. The Amphenol ICC part supports 4.15mm, 4.5mm, 5mm, 5.5mm, 6mm, 7mm, and 7.52mm stacking heights. The 5mm and 7mm options are common to both, ensuring compatibility for standard mating configurations.

Q: What is the difference in contact finish thickness?

A: The Molex part specifies 30.0µin (0.76µm) gold thickness, while the Amphenol ICC part specifies 15.0µin (0.38µm). Both thicknesses meet industry standards for contact durability and electrical performance in rectangular connector applications.

Q: Is the Amphenol ICC part available in the same packaging as the Molex original?

A: The Amphenol ICC part is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility; it only impacts receiving, storage, and handling procedures.
