Molex 0877003002 Equivalent & Substitute Parts

Part Overview

The Molex 0877003002 is a 31-position backplane connector receptacle featuring female sockets and blade sockets for board edge mounting applications. This connector is part of the EXTreme PowerPlus 87700 series and is designed for through-hole, right-angle solder termination with integrated board lock and guide pin features.

The 0877003002 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this connector type remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0877003002 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle with female sockets and blade sockets configuration
• Position Count: Exactly 31 positions
• Pitch Spacing: 0.100" (2.54mm) standard spacing
• Row Configuration: 4-row arrangement
• Mounting Geometry: Board edge mounting with through-hole, right-angle orientation
• Termination Method: Solder termination
• Contact Layout: 24 signal positions and 7 power positions
• Mechanical Features: Board lock and guide pin integration
• Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
• Environmental Compliance: UL94 V-0 flammability rating, operating range -20°C to 105°C

The Amphenol ICC (FCI) 51762-10702400AALF meets all these critical parameters and qualifies as a direct substitute for the obsolete Molex 0877003002.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51762-10702400AALF is the qualified substitute for the obsolete Molex 0877003002. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including position count, pitch, mounting configuration, and contact layout.

The substitute part carries active product status, ensuring ongoing availability and supply chain support. Both parts meet UL94 V-0 flammability requirements and operate across the identical temperature range of -20°C to 105°C. RoHS compliance is maintained in both variants, with the substitute offering RoHS Compliant status.

The contact finish specifications are equivalent at 30.0µin (0.76µm) gold plating. The Amphenol ICC part offers optional GXT™ contact finish enhancement, which does not affect substitution eligibility for applications requiring standard gold finish.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51762-10702400AALF directly replace the Molex 0877003002 in existing designs?

A: Yes. Both connectors share identical specifications for position count (31), pitch (0.100"), row configuration (4), mounting type (board edge, through-hole, right-angle), contact layout (24 signal, 7 power), and termination method (solder). Mechanical and electrical compatibility is confirmed.

Q: What is the primary reason for substitution?

A: The Molex 0877003002 is classified as obsolete. The Amphenol ICC 51762-10702400AALF is an active product with confirmed supply availability, making it the appropriate choice for new procurement and legacy system support.

Q: Are there differences in packaging between these parts?

A: The Molex 0877003002 packaging specification is not provided. The Amphenol ICC 51762-10702400AALF is supplied in Tray packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both parts meet UL94 V-0 flammability rating, operate across -20°C to 105°C, maintain Moisture Sensitivity Level 1 (Unlimited), and comply with RoHS requirements. The substitute part is REACH Affected, while the original part is REACH Unaffected; however, this does not impact functional substitution.

Q: Is the GXT™ contact finish option on the Amphenol ICC part a requirement for substitution?

A: No. The GXT™ finish is an optional enhancement. Standard gold finish at 30.0µin (0.76µm) is available and matches the original Molex specification exactly.
