87471-640 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87471-640 is an 80-position receptacle connector with 0.050" (1.27mm) pitch, designed for surface mount board-to-board applications. This connector features a Rib-Cage™ series design with gold-plated mating contacts and push-pull fastening. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 87471-640 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (80), mating pitch (0.050"), number of rows (2), row spacing (0.050"), mounting type (surface mount), style (board to board), fastening type (push-pull), and contact finish (gold). Parts meeting these criteria are classified as direct substitutes.

The 87471-640LF is a direct manufacturer equivalent from Amphenol ICC, differing only in packaging (tube) and compliance status. The 104652-8 from TE Connectivity AMP Connectors meets all critical electrical and mechanical parameters but represents a cross-manufacturer substitute with variations in series designation, insulation material, and contact post finish specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete 87471-640, the 87471-640LF is the primary substitute. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The 87471-640LF is sourced from the same manufacturer and series, ensuring design compatibility with minimal risk.

The 104652-8 from TE Connectivity AMP Connectors serves as a cross-manufacturer alternative when 87471-640LF availability is constrained. This part meets all critical mating and mounting parameters but introduces variations in insulation material (Liquid Crystal Polymer versus Thermoplastic, Glass Filled), contact post finish (Tin-Lead versus Tin), and contact material specification (Copper Alloy versus Beryllium Copper). The 104652-8 provides documented operating temperature range (-65°C ~ 105°C) and specified mated stacking heights, which are not provided for the Amphenol ICC parts.

Selection between these substitutes depends on compliance requirements, material specifications, and thermal operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 87471-640LF be used as a direct replacement for the 87471-640?

A: Yes. The 87471-640LF is a direct manufacturer equivalent with identical electrical and mechanical specifications. The primary differences are packaging format (tube versus bulk) and compliance status (RoHS compliant versus non-compliant). Both parts are from Amphenol ICC and belong to the Rib-Cage™ series.

Q: What are the key differences between the Amphenol ICC 87471-640LF and the TE Connectivity 104652-8?

A: Both parts share identical mating pitch (0.050"), number of positions (80), number of rows (2), row spacing (0.050"), mounting type (surface mount), and fastening type (push-pull). Differences include: manufacturer series (Rib-Cage™ versus AMPMODU 50/50 Grid), insulation material (Thermoplastic, Glass Filled versus Liquid Crystal Polymer), contact post finish (Tin versus Tin-Lead), contact material (Beryllium Copper versus Copper Alloy), and contact post finish thickness (100.0µin versus 150.0µin). The 104652-8 provides specified operating temperature range and mated stacking heights.

Q: Are there packaging considerations when substituting these parts?

A: The 87471-640 original part has unspecified packaging. The 87471-640LF is supplied in tube packaging. The 104652-8 is also supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which substitute should be selected for RoHS-compliant applications?

A: The 87471-640LF is RoHS compliant. The 104652-8 is RoHS non-compliant. For RoHS-compliant designs, the 87471-640LF is the appropriate selection.

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

A: The 87471-640 and 87471-640LF use tin contact post finish at 100.0µin (2.54µm) thickness. The 104652-8 uses tin-lead contact post finish at 150.0µin (3.81µm) thickness. This difference may affect soldering characteristics and long-term reliability in specific thermal cycling environments.

Q: Can the 104652-8 be used in applications with temperature extremes?

A: The 104652-8 specifies an operating temperature range of -65°C to 105°C. The 87471-640 and 87471-640LF do not provide operating temperature specifications. If your application requires documented temperature performance, the 104652-8 provides this specification.
