Amphenol ICC 87409-105CT Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87409-105CT is a surface mount rectangular connector header from the Rib-Cage™ III series, featuring 10 positions arranged in 2 rows with 0.050" (1.27mm) pitch. This connector is designed for board-to-board applications with shrouded 4-wall construction and push-pull fastening. The part is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 87409-105CT is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (10 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting technology (Surface Mount)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Contact geometry and mating length (Square, 0.130")
• Insulation material and flammability rating (Thermoplastic Glass Filled, UL94 V-0)
• Operating temperature range (-55°C ~ 130°C)
• Mated stacking height (6.42mm)

The identified substitute parts maintain full electrical and mechanical compatibility with the original 87409-105CT specification. Differences in product status, RoHS compliance, and contact finish post material do not affect functional interchangeability in board-to-board mating applications.

Parameter Comparison

Engineering Selection Recommendations

The 87409-105CT is classified as obsolete and is not RoHS compliant. Both substitute parts—87409-105CTLF and 87409-105LF—are active products with RoHS compliance status, making them suitable for new designs and ongoing production support.

For applications requiring RoHS compliance, either 87409-105CTLF or 87409-105LF is appropriate. The primary difference between these two substitutes is the inclusion of "Pick and Place" features in the 87409-105CTLF, which may provide manufacturing advantages in automated assembly environments.

The contact finish post material differs between the original part (Tin-Lead) and both substitutes (Tin). This change reflects current manufacturing standards and does not affect electrical or mechanical compatibility in board-to-board mating applications.

Frequently Asked Questions (FAQ)

Q: Can 87409-105CTLF and 87409-105LF be used interchangeably with 87409-105CT?

A: Yes. Both substitute parts maintain full electrical and mechanical compatibility with the original 87409-105CT. All critical parameters—connector type, position count, pitch, mounting method, shrouding, fastening mechanism, contact geometry, insulation material, operating temperature range, and mated stacking height—are identical.

Q: What is the significance of the contact finish post material change from Tin-Lead to Tin?

A: The change from Tin-Lead to Tin in the post contact finish reflects current manufacturing practices and RoHS compliance requirements. This change does not affect the electrical or mechanical performance of the connector in board-to-board applications.

Q: Why is the original 87409-105CT listed as obsolete?

A: The 87409-105CT is obsolete due to its RoHS non-compliant status and the availability of functionally equivalent active alternatives. The substitute parts 87409-105CTLF and 87409-105LF provide the same electrical and mechanical functionality with current compliance certifications.

Q: What does the "CTLF" suffix in 87409-105CTLF indicate?

A: The "CTLF" suffix indicates the part includes lead-free contact finish post material (Tin) and is packaged in Tube format. The "LF" designation in 87409-105LF similarly indicates lead-free post finish.

Q: Are there packaging differences between the substitute parts?

A: Both 87409-105CTLF and 87409-105LF are supplied in Tube packaging. The original 87409-105CT packaging specification is not provided in the technical data.

Q: What is the current rating for these connectors?

A: The substitute parts 87409-105CTLF and 87409-105LF are rated for 1A DC. The current rating for the original 87409-105CT is not specified in the available technical documentation.

Q: Do these connectors support automated assembly?

A: The 87409-105CTLF includes "Pick and Place" features to support automated assembly processes. The 87409-105LF includes "Board Guide" features. Both are surface mount connectors suitable for modern manufacturing environments.
