Amphenol ICC 65043-026LF Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 65043-026LF is a 22-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for crimp contact termination in free-hanging inline applications. This component is classified as Active product status and serves as a standard interconnect solution in electronic assemblies requiring dual-row female socket housings.

Substitute parts become necessary when addressing supply chain constraints, design revisions requiring alternative material properties, or operational environment changes that demand extended temperature ranges or different insulation characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the 65043-026LF is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: All substitutes must be receptacle housings with female socket contacts
Position Count & Pitch: Exactly 22 positions at 0.100" (2.54mm) pitch with 2-row configuration and 0.100" row spacing
Mounting & Termination: Free hanging inline mounting with crimp contact termination
Moisture Sensitivity: MSL 1 rating (Unlimited) across all qualified substitutes

The four identified substitute parts meet these core electrical and mechanical requirements. Variations in insulation material, color, temperature range, and manufacturer series do not affect functional interchangeability for the specified connector interface.

Engineering Selection Recommendations

All five connector housings maintain Active product status and satisfy RoHS compliance requirements. Selection among these parts should be based on the following documented characteristics:

Amphenol ICC 65043-026LF (Primary Part): Standard operating temperature range of -40°C to 105°C with modified polyphenylene insulation. RoHS Compliant status with REACH Affected designation.

Amphenol ICC 65239-011LF: Extended operating temperature range of -65°C to 125°C with thermoplastic glass-filled insulation. Suitable for applications requiring broader thermal performance. RoHS Compliant with REACH Affected status. Blue color variant available.

Molex 0022552223: Matches primary part temperature range (-40°C to 105°C) with polyester glass-filled insulation. ROHS3 Compliant with REACH Unaffected status. Represents alternative manufacturer sourcing within equivalent thermal envelope.

TE Connectivity 1-87456-7: Extended lower temperature limit (-65°C) with polyamide nylon glass-filled insulation. RoHS Compliant status. Vendor-undefined REACH status requires verification for specific applications.

Harwin M20-1071100: Restricted operating temperature range (-25°C to 85°C) with polyphenylene ether and polystyrene insulation. ROHS3 Compliant with REACH Unaffected status. Suitable only for applications within specified thermal limits.

Frequently Asked Questions (FAQ)

Q: Can the 65043-026LF be directly replaced with any of these substitute parts?

A: Yes, all four substitute parts are functionally equivalent at the connector interface level. They share identical position count (22), pitch (0.100"), row configuration (2 rows at 0.100" spacing), mounting type (free hanging inline), and contact termination method (crimp). Physical interchangeability is confirmed for mating with standard 0.100" pitch male connectors.

Q: What are the key differences between these substitute parts?

A: Differences exist in operating temperature range, insulation material composition, color, and manufacturer series. The Amphenol 65239-011LF and TE Connectivity 1-87456-7 offer extended lower temperature capability (-65°C). The Harwin M20-1071100 has a restricted upper temperature limit (85°C). Insulation materials vary between polyphenylene, thermoplastic, polyester, polyamide, and polyphenylene ether formulations.

Q: Are there compliance differences I should consider?

A: All parts are RoHS compliant. The Molex 0022552223 and Harwin M20-1071100 carry ROHS3 designation, while Amphenol and TE Connectivity parts are RoHS Compliant. REACH status varies: Amphenol 65043-026LF and 65239-011LF are REACH Affected; Molex and Harwin parts are REACH Unaffected; TE Connectivity status is Vendor Undefined.

Q: Which substitute should I select for extreme temperature applications?

A: The Amphenol ICC 65239-011LF (-65°C to 125°C) and TE Connectivity 1-87456-7 (-65°C to 105°C) provide extended lower temperature performance. The Harwin M20-1071100 is limited to -25°C to 85°C and is unsuitable for low-temperature environments.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All five connector housings carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can I mix these parts within the same assembly?

A: Electrical and mechanical compatibility is confirmed across all parts for the connector interface. However, design consistency and supply chain management typically favor standardizing on a single part number per assembly.
