Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0874331330 is determined by strict alignment of the following critical parameters:

• Connector type: Receptacle with outer shroud contacts
• Electrical interface: 25 positions in 2-row configuration
• Contact pitch: 0.039" (1.00mm)
• Mounting technology: Surface mount
• Contact material: Gold plating
• Moisture sensitivity: MSL 1 or better
• Physical compatibility: Mated stacking heights and height above board within acceptable tolerance ranges

The Amphenol ICC (FCI) 91921-31125LF meets all substitution criteria. This part maintains identical position count, pitch, row configuration, and mounting method. Physical dimensions remain compatible within the specified stacking height and board clearance parameters.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 91921-31125LF is the qualified substitute for the obsolete Molex 0874331330. This part maintains full electrical and mechanical compatibility across all critical interface parameters.

The 91921-31125LF offers the additional advantage of active product status, ensuring continued availability and supply chain support. The part is RoHS compliant, providing regulatory alignment for new designs and manufacturing environments with RoHS requirements.

The contact finish thickness differs between the two parts (30.0µin for the original versus 15.0µin for the substitute). Both values remain within acceptable ranges for gold-plated connector contacts in standard applications. The substitute supports expanded mated stacking height options (4.15mm through 7.52mm) compared to the original (5mm, 7mm), providing additional mechanical flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 91921-31125LF be used as a direct replacement for the Molex 0874331330?

A: Yes. Both parts share identical position count, pitch, row configuration, mounting method, and contact finish material. Physical dimensions are compatible within standard tolerance ranges for connector applications.

Q: What is the significance of the product status difference?

A: The Molex 0874331330 is obsolete, meaning the manufacturer no longer produces or supports this part. The Amphenol ICC 91921-31125LF is active, ensuring ongoing availability, technical support, and supply chain continuity.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory and manufacturing consideration rather than an electrical or mechanical interface parameter. The RoHS-compliant substitute is suitable for applications and manufacturing environments requiring RoHS adherence.

Q: Are the contact finish thickness values significant?

A: Both contact finish thicknesses (30.0µin and 15.0µin) are within acceptable ranges for gold-plated connector contacts. The difference does not affect electrical performance or mechanical compatibility in standard applications.

Q: What are the mated stacking height options for each part?

A: The Molex 0874331330 supports 5mm and 7mm stacking heights. The Amphenol ICC 91921-31125LF supports 4.15mm, 4.5mm, 5mm, 5.5mm, 6mm, 7mm, and 7.52mm stacking heights, providing expanded mechanical flexibility.

Q: Are there packaging differences between these parts?

A: The Molex 0874331330 packaging is not specified in the available data. The Amphenol ICC 91921-31125LF is supplied in Tape & Reel (TR) packaging, standard for surface mount connector production.
