Amphenol ICC 66901-140 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66901-140 is a 40-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination and gold plating. This connector is part of the Quickie™ series and features a 0.100" (2.54mm) pitch with 2-row configuration for ribbon cable applications. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible connectivity solutions.

Substitute Part Grouping Explanation

Substitution for the 66901-140 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), position count (40), pitch (0.100"/2.54mm), row configuration (2 rows at 0.100" spacing), mounting style (free hanging in-line), cable termination method (IDC), and wire type (ribbon cable). All substitute parts maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories:

Direct Amphenol ICC Substitute: The 66901-140LF maintains identical specifications to the main part while offering active product status and RoHS compliance.

Cross-Manufacturer Substitutes: HARTING SEK series (09185406803, 09185406813, 09185407813) and 3M 891 series (89140-0101) provide functional equivalence with specified wire gauge compatibility (26-28 AWG) and active product status.

Engineering Selection Recommendations

For RoHS-compliant applications: The 66901-140LF is the direct replacement, maintaining Amphenol ICC manufacturing and GXT™ gold contact finish while achieving RoHS compliance. This part is recommended as the primary substitute for the obsolete 66901-140.

For cross-manufacturer flexibility: HARTING SEK series connectors (09185406803, 09185406813, 09185407813) and 3M 891 series (89140-0101) provide active product status with ROHS3 compliance. These parts include polarizing key features for enhanced mating security. HARTING parts 09185406813 and 09185407813 include strain relief for improved cable retention.

For maximum inventory availability: The 3M 89140-0101 offers the highest current stock level (11,058 pcs) with active product status and ROHS3 compliance, suitable for high-volume applications.

All substitute parts maintain electrical and mechanical compatibility through identical pitch, position count, row configuration, and IDC termination specifications.

Frequently Asked Questions (FAQ)

Q: Can the 66901-140 be directly replaced with the 66901-140LF?

A: Yes. The 66901-140LF maintains identical electrical and mechanical specifications including 40 positions, 0.100" pitch, 2-row configuration, IDC termination, and gold contact finish. The primary difference is active product status and RoHS compliance.

Q: What are the key compatibility criteria for substitution?

A: Substitutes must maintain: 40-position count, 0.100" (2.54mm) pitch, 2-row configuration at 0.100" row spacing, receptacle connector type with female socket contacts, free hanging in-line mounting, IDC cable termination for ribbon cable, and gold contact finish.

Q: Are HARTING and 3M substitutes mechanically compatible?

A: Yes. HARTING SEK series and 3M 891 series connectors maintain identical pitch, position count, row spacing, and mounting configuration. Additional features such as polarizing keys and strain relief enhance mating security without affecting core mechanical compatibility.

Q: What is the difference between packaging options?

A: The 66901-140LF is supplied in tube packaging, HARTING 09185406813 in tray packaging, while HARTING 09185406803, 09185407813, and 3M 89140-0101 are supplied in bulk packaging. Packaging does not affect electrical or mechanical performance.

Q: Are all substitutes RoHS compliant?

A: The 66901-140 is RoHS non-compliant. All substitute parts (66901-140LF, HARTING SEK series, and 3M 891 series) are RoHS or ROHS3 compliant, meeting current regulatory requirements.

Q: What wire gauge compatibility should be considered?

A: The original 66901-140 does not specify wire gauge. Cross-manufacturer substitutes (HARTING and 3M) are rated for 26-28 AWG ribbon cable, which is standard for 0.100" pitch IDC connectors.
