Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0876972002 is determined by strict alignment of the following electrical and mechanical parameters:

• Number of Positions: 28 positions (exact match required)
• Pitch: 0.100" (2.54mm) (exact match required)
• Number of Rows: 4 rows (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Method: Press-Fit or compatible termination (Press-Fit with Solder acceptable)
• Contact Layout: 24 Signal, 4 Power (exact match required)
• Contact Finish: Gold (exact match required)
• Contact Finish Thickness: 30.0µin (0.76µm) (exact match required)
• Operating Temperature Range: -20°C ~ 105°C (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The Amphenol ICC (FCI) 51940-235LF meets all these criteria and qualifies as a direct substitute. This part is currently in active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51940-235LF is the qualified substitute for the Molex 0876972002. Selection is based on the following engineering criteria:

Compliance and Certification: Both parts meet UL94 V-0 flammability requirements and maintain equivalent RoHS compliance status. The substitute part carries active RoHS Compliant certification, while the original part is ROHS3 Compliant.

Product Status: The original Molex 0876972002 is obsolete, creating supply and support limitations. The Amphenol ICC 51940-235LF is in active production, ensuring availability and ongoing manufacturer support.

Electrical and Mechanical Compatibility: All critical parameters—position count, pitch, row configuration, mounting method, contact layout, finish specifications, and operating temperature range—are identical between the two parts. The substitute part offers dual termination capability (Press-Fit and Solder), providing additional flexibility in assembly processes.

Packaging and Inventory: The substitute part is supplied in Tray packaging with confirmed inventory availability, supporting production and replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51940-235LF be used as a direct replacement for the Molex 0876972002?

A: Yes. The Amphenol ICC 51940-235LF meets all electrical and mechanical specifications required for direct substitution. Both parts share identical position count (28), pitch (0.100"), row configuration (4), contact layout (24 Signal, 4 Power), contact finish (Gold, 30.0µin), operating temperature range (-20°C ~ 105°C), and flammability rating (UL94 V-0).

Q: What is the primary reason for substitution?

A: The Molex 0876972002 is classified as obsolete. The Amphenol ICC 51940-235LF is an active production part, ensuring long-term supply chain continuity and manufacturer support.

Q: Are there differences in termination methods between these parts?

A: The original Molex part uses Press-Fit termination exclusively. The Amphenol ICC substitute offers both Press-Fit and Solder termination options. Press-Fit termination remains fully compatible with the original application requirements.

Q: Do both parts have the same contact finish specifications?

A: Yes. Both parts feature gold contact finish at 30.0µin (0.76µm) thickness. The Amphenol ICC part offers an additional option with Gold, GXT™ finish, but standard gold finish is available and matches the original specification.

Q: What is the packaging difference?

A: The Molex 0876972002 packaging type is not specified in available documentation. The Amphenol ICC 51940-235LF is supplied in Tray packaging with 1030 pieces in current inventory.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The Molex 0876972002 is ROHS3 Compliant, and the Amphenol ICC 51940-235LF is RoHS Compliant. Both meet current regulatory requirements for restricted substance elimination.
