Amphenol ICC 87409-140 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87409-140 is a surface mount rectangular connector header designed for board-to-board applications. This 80-position, dual-row connector operates within the -55°C to 130°C temperature range and is classified as Active product status. Finding equivalent and substitute parts becomes necessary when addressing RoHS compliance requirements, managing inventory constraints, or accommodating specific application demands while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 87409-140 is determined by strict alignment with the following critical parameters: 80-position count, dual-row configuration, 0.050" (1.27mm) mating pitch, 0.050" (1.27mm) row spacing, surface mount termination, shrouded 4-wall design, board-to-board style, and push-pull fastening. The substitute parts identified maintain these core electrical and mechanical specifications, ensuring functional interchangeability within the defined application envelope.

The 87409-140LF represents a direct manufacturer equivalent with identical specifications except for RoHS compliance status and post-contact finish material. The TE Connectivity 104655-9 functions as a cross-manufacturer substitute, maintaining critical dimensional and electrical parameters while introducing variations in contact geometry, insulation material, and thermal operating range that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 87409-140LF serves as the primary direct substitute for the 87409-140, offering identical electrical and mechanical specifications with the addition of RoHS compliance. This substitution is appropriate for applications requiring regulatory compliance without functional modification. Both parts maintain Active product status and are manufactured by Amphenol ICC within the Rib-Cage™ III series.

The TE Connectivity 104655-9 functions as a cross-manufacturer alternative suitable for applications where thermal operating range does not exceed 105°C and current requirements per contact do not exceed 0.5A. This part introduces dimensional variations in contact length (0.120" versus 0.130") and contact geometry (circular versus square), along with different insulation material composition. Selection of this substitute requires confirmation that these parameter differences align with specific application constraints and PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the 87409-140LF be used as a direct replacement for the 87409-140?

A: Yes. The 87409-140LF maintains identical electrical and mechanical specifications including pitch, row spacing, number of positions, contact length, insulation height, and current rating. The primary difference is RoHS compliance status and post-contact finish material (Tin versus Tin-Lead).

Q: What are the key differences between the 87409-140 and the TE Connectivity 104655-9?

A: Critical differences include contact length (0.130" versus 0.120"), contact shape (square versus circular), insulation material (Thermoplastic Glass Filled versus Liquid Crystal Polymer), operating temperature range (-55°C to 130°C versus -65°C to 105°C), and current rating (1A DC versus 0.5A per contact). These variations require application-specific evaluation.

Q: Is the 104655-9 suitable for high-temperature applications?

A: No. The 104655-9 operates within -65°C to 105°C, which is lower than the 87409-140 maximum of 130°C. Applications requiring operation above 105°C must use the 87409-140 or 87409-140LF.

Q: What is the impact of the contact length difference between the 87409-140 and 104655-9?

A: The 87409-140 features 0.130" (3.30mm) mating contact length compared to 0.120" (3.05mm) for the 104655-9. This 0.010" difference may affect mating force, contact pressure, and PCB stack-up compatibility. Mechanical verification is required before substitution.

Q: Does the circular contact shape of the 104655-9 affect compatibility?

A: Contact shape differences (square versus circular) may influence contact resistance, mating force characteristics, and receptacle compatibility. The 104655-9 is designed for use with TE Connectivity receptacles within the AMPMODU 50/50 Grid series and may not be compatible with Amphenol ICC Rib-Cage™ III receptacles.

Q: What is the current rating difference between these parts?

A: The 87409-140 and 87409-140LF are rated at 1A DC. The 104655-9 is rated at 0.5A per contact. Applications requiring current levels between 0.5A and 1A per contact must use the Amphenol ICC parts.
