Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0873813474 is determined by strict alignment of the following parameters:

• Connector type: Receptacle
• Position count: 34 positions
• Mating pitch: 0.079" (2.00mm)
• Row configuration: 2 rows with 0.079" (2.00mm) spacing
• Mounting method: Surface mount with solder termination
• Fastening mechanism: Push-pull
• Contact finish: Gold-plated mating surface
• Insulation height: 0.177" (4.50mm)
• Contact shape: Square

The Amphenol ICC (FCI) part 55510-134LF satisfies all these core parameters, establishing it as a direct substitute within the rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0873813474 and Amphenol ICC 55510-134LF maintain active product status and comply with applicable regulatory standards. The Molex part carries ROHS3 compliance with REACH Unaffected status. The Amphenol ICC part carries RoHS compliance with REACH Affected status. Both parts are classified as EAR99 for export control purposes and share the same HTSUS commodity code.

The Amphenol ICC substitute provides higher voltage (200V vs. 125V) and current (2A vs. 1.9A) ratings, along with an extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C). Both parts feature unlimited moisture sensitivity level rating and identical mechanical interfaces.

Frequently Asked Questions (FAQ)

Q: What determines if the Amphenol ICC 55510-134LF can replace the Molex 0873813474?

A: Substitution is valid when the connector maintains identical mating pitch (0.079"), position count (34), row configuration (2 rows), mounting method (surface mount), fastening type (push-pull), and contact finish (gold). Both parts satisfy these requirements.

Q: Are there differences in electrical performance between these parts?

A: The Amphenol ICC part has higher voltage and current ratings. The Molex part is rated 125V at 1.9A, while the Amphenol ICC part is rated 200V at 2A. Both operate across overlapping temperature ranges, with the Amphenol ICC part extending to 125°C maximum.

Q: Do packaging considerations affect substitution?

A: Both parts are supplied in tube packaging. Inventory availability differs: Molex has 991 units in stock, while Amphenol ICC has 1779 units available.

Q: What are the compliance differences?

A: The Molex part is ROHS3 compliant and REACH unaffected. The Amphenol ICC part is RoHS compliant and REACH affected. Both are classified as EAR99 for export control.

Q: Can these connectors be used interchangeably in existing designs?

A: Mechanical and electrical interface compatibility is established through matching pitch, position count, row spacing, and fastening mechanisms. The higher ratings of the Amphenol ICC part provide additional design margin in applications operating within the Molex part's original specifications.
