Amphenol ICC 87606-402 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87606-402 is a 4-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in automotive, industrial, telecommunications, and general purpose environments. This part operates as a through-hole solder-terminated female socket connector in the Dubox™ series.

The 87606-402 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems.

Substitute Part Grouping Explanation

Substitution eligibility for the 87606-402 is determined by the following critical parameters:

Primary Compatibility Criteria:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (4)
Pitch - mating (0.100" / 2.54mm)
Number of rows (2)
Row spacing - mating (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Solder)
Insulation material (Thermoplastic, Glass Filled)
Material flammability rating (UL94 V-0)

Identified Substitutes:

87606-402LF — Direct substitute within the same Dubox™ series. Maintains identical mechanical and electrical interface specifications. Primary difference: contact finish changed from Tin-Lead to Tin, and RoHS compliance status upgraded from non-compliant to compliant.

98424-S52-20ULF — Cross-series substitute from the Minitek® 2.00mm series. This part does not meet the primary compatibility criteria. It is a header connector (not receptacle), operates at 0.079" (2.00mm) pitch (not 0.100"), contains 20 positions (not 4), and uses surface mount technology (not through hole). This part is not electrically or mechanically compatible with the 87606-402 and should not be considered a functional substitute.

Engineering Selection Recommendations

87606-402LF is the appropriate substitute for the obsolete 87606-402. Both parts maintain identical mechanical and electrical interface specifications within the Dubox™ series. The 87606-402LF is currently in active production status with 684 units in stock. The contact finish change from Tin-Lead to Tin and the upgrade to RoHS compliance represent improvements in regulatory alignment and environmental standards. The part retains the same UL94 V-0 flammability rating and thermoplastic glass-filled insulation material.

98424-S52-20ULF is not suitable as a substitute. Fundamental incompatibilities exist across multiple critical parameters: different connector type (header vs. receptacle), different contact type (male pin vs. female socket), different pitch specification (0.079" vs. 0.100"), different number of positions (20 vs. 4), and different mounting technology (surface mount vs. through hole). These differences prevent direct mechanical and electrical compatibility with the 87606-402.

Frequently Asked Questions (FAQ)

Q: Can the 87606-402LF directly replace the 87606-402 in existing designs?

A: Yes. The 87606-402LF maintains identical connector type, contact type, position count, pitch, row spacing, mounting type, and termination method. The contact finish change from Tin-Lead to Tin does not affect mechanical compatibility. The upgrade to RoHS compliance is a regulatory improvement.

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

A: The contact finish change reflects compliance with lead-free soldering standards. Tin provides equivalent electrical and mechanical performance for the specified applications while meeting environmental regulations.

Q: Why is 98424-S52-20ULF listed as a substitute if it is incompatible?

A: The 98424-S52-20ULF is listed in the original substitute field but does not meet the compatibility criteria for the 87606-402. It represents a different connector family with fundamentally different specifications and should not be used as a replacement.

Q: Are there any thermal or electrical performance differences between 87606-402 and 87606-402LF?

A: No thermal or electrical performance parameters are provided in the specifications for either part. Both parts are specified for identical applications: automotive, general purpose, industrial, and telecommunications.

Q: What is the inventory status for the recommended substitute?

A: The 87606-402LF has 684 units in stock as new original inventory, ensuring availability for production requirements.
