Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0874331130 is determined by strict equivalence across the following critical parameters:

• Connector type and contact configuration (Receptacle, Outer Shroud Contacts)
• Position count (21 positions)
• Pitch specification (1.00mm)
• Row configuration (2 rows)
• Mounting technology (Surface Mount)
• Contact finish material (Gold)
• Presence of board guide feature
• Moisture sensitivity rating (MSL 1)

The Amphenol ICC (FCI) part number 91930-21121LF meets all these criteria and qualifies as a direct substitute. Both connectors share identical electrical and mechanical interfaces, enabling pin-for-pin replacement in applications designed for the original Molex component.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 91930-21121LF is the qualified substitute for the obsolete Molex 0874331130. Selection of this alternative part is supported by the following factors:

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

Compliance: The 91930-21121LF achieves RoHS compliance, meeting current regulatory requirements for electronic components in many jurisdictions. The original Molex part does not meet this standard.

Electrical and Mechanical Compatibility: Both connectors maintain identical pitch, position count, row configuration, and mounting technology. Height above board measurements are equivalent within engineering tolerance (3.30mm vs. 3.28mm).

Moisture Sensitivity: Both parts carry MSL 1 rating, indicating unlimited shelf life and identical handling requirements.

Feature Enhancement: The substitute part includes solder retention in addition to the board guide feature present in the original, providing improved manufacturing robustness.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 91930-21121LF directly replace the Molex 0874331130 in existing designs?

A: Yes. Both connectors share identical pitch (1.00mm), position count (21), row configuration (2), and mounting type (Surface Mount). The receptacle outer shroud contact configuration and board guide feature are equivalent. Height above board measurements are within engineering tolerance.

Q: What is the difference in contact finish between the two parts?

A: The Molex 0874331130 specifies gold contact finish at 30.0µin thickness. The Amphenol ICC 91930-21121LF offers gold or gold with GXT™ plating at 15.0µin thickness. Both finishes provide equivalent electrical performance for this connector class.

Q: Are there differences in mated stacking height options?

A: The Molex part supports 5mm and 7mm stacking heights. The Amphenol ICC substitute offers expanded options: 4.15mm, 4.5mm, 5mm, 5.5mm, 6mm, 7mm, and 7.52mm. Designs requiring 5mm or 7mm stacking remain fully compatible.

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

A: The substitute part is RoHS compliant, meeting current environmental and regulatory standards. The original Molex part is non-compliant. For new designs or applications subject to RoHS requirements, the Amphenol ICC part is the appropriate selection.

Q: Does the solder retention feature on the substitute part affect compatibility?

A: No. Solder retention is an additional manufacturing feature that enhances assembly robustness. It does not alter electrical or mechanical interface characteristics and does not impact compatibility with existing designs.

Q: What is the packaging difference?

A: The Molex part is supplied without specified packaging. The Amphenol ICC 91930-21121LF is supplied in tube packaging, which is standard for surface mount connectors and facilitates automated assembly processes.
