Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 46232-000LF is determined by the following core parameters:

• Wire Gauge Compatibility: 22-26 AWG (all substitute parts match this specification)
• Contact Termination Method: Crimp termination (all substitute parts use crimp termination)
• Moisture Sensitivity Level: MSL 1 (Unlimited) - all substitute parts meet or exceed this requirement
• Environmental Compliance: REACH Unaffected status maintained across all alternatives
• Electrical Classification: HTSUS 8536.90.4000 (rectangular connector classification)

Substitute parts are grouped into two functional categories based on contact configuration:

Category A - Socket Contact (Direct Functional Equivalent)

• Amphenol ICC 46231-000LF: Active status socket contact with matching wire gauge and crimp termination
• Molex 0503728000: Socket contact configuration with tin finish alternative

Category B - Non-Gendered Contact (Functional Alternative)

• Molex KK 2578 series (0008500111, 0008550123, 0008550137, 0008580125, 0008650110)
• Molex KK Trifurcon 7258 series (0008560123, 0008650121, 0008650122)

Non-gendered contacts provide functional equivalence for applications where socket-specific mating is not required, offering broader compatibility within connector systems.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 46231-000LF

The 46231-000LF is the manufacturer-recommended direct substitute, maintaining socket contact configuration identical to the 46232-000LF. This part carries active product status with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The gold contact finish and 22-26 AWG wire gauge specification remain unchanged. Packaging is provided in Tape & Reel format with 982 units in current inventory.

Secondary Recommendation: Molex 0503728000 (Socket Contact Alternative)

For applications requiring socket contact configuration with alternative supplier sourcing, the Molex 0503728000 provides socket contact geometry with tin finish. This part is classified as active with ROHS3 compliance and offers the highest inventory availability (254,272 units) in Cut Tape packaging. The tin finish provides equivalent corrosion resistance for MSL 1 applications.

Functional Alternative: Molex KK 2578 and KK Trifurcon 7258 Series (Non-Gendered Contacts)

Non-gendered contact alternatives are suitable for applications where connector mating does not require socket-specific geometry. These parts maintain 22-26 AWG wire gauge and crimp termination specifications. Multiple packaging options are available (Tape & Reel, Cut Tape, Bulk) with varying inventory levels. Gold finish options with 30.0µin thickness are available across multiple part numbers (0008550123, 0008550137, 0008650110, 0008650121, 0008650122). Tin finish alternative (0008500111) is available for cost-sensitive applications.

All substitute parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with the original specification requirements.

Frequently Asked Questions (FAQ)

Q: Can the 46231-000LF directly replace the obsolete 46232-000LF?

A: Yes. The 46231-000LF is the manufacturer-recommended substitute with identical socket contact configuration, wire gauge (22-26 AWG), crimp termination, and gold finish. The primary difference is active product status and RoHS compliance certification. Contact finish thickness is reduced from 74.8µin to 40.0µin, which remains within acceptable parameters for MSL 1 applications.

Q: What is the difference between socket and non-gendered contacts?

A: Socket contacts are specifically designed to receive pin contacts in mating connector pairs. Non-gendered contacts can function as either pin or socket depending on connector assembly configuration. For applications requiring specific socket mating geometry, socket contact parts (46231-000LF or 0503728000) are required. Non-gendered alternatives are suitable only when connector mating configuration does not mandate socket-specific geometry.

Q: Are tin finish contacts equivalent to gold finish contacts?

A: Tin and gold finishes provide different electrical and corrosion resistance characteristics. Gold finish (46232-000LF, 46231-000LF, non-gendered gold alternatives) offers superior corrosion resistance and lower contact resistance. Tin finish (0008500111, 0503728000) is suitable for MSL 1 applications with adequate environmental protection. Selection depends on specific application requirements for contact resistance and corrosion resistance.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR) for automated assembly, Cut Tape (CT) for mixed-volume procurement, and Bulk for high-volume applications. The 46231-000LF is supplied in Tape & Reel format. Molex alternatives offer flexibility across all three packaging types, with 0008560123 and 0008650121 available in Cut Tape and 0008650122 available in Bulk.

Q: Do all substitute parts meet REACH and RoHS requirements?

A: The original 46232-000LF is REACH Unaffected with no RoHS status specified. The 46231-000LF is RoHS Compliant. All Molex substitute parts are ROHS3 Compliant and REACH Unaffected. For applications requiring specific RoHS certification levels, the 46231-000LF and all Molex alternatives meet current regulatory requirements.

Q: What is the significance of contact finish thickness variation?

A: Contact finish thickness affects durability and contact resistance over the component lifecycle. The original 46232-000LF specifies 74.8µin (1.90µm) gold thickness. Substitute parts range from 15.0µin to 100.0µin depending on part number and finish type. All specified thicknesses are suitable for MSL 1 (Unlimited) moisture sensitivity applications. Selection should consider expected contact cycle count and environmental exposure.

Q: Which substitute part offers the best inventory availability?

A: The Molex 0503728000 offers the highest inventory availability with 254,272 units in stock. This socket contact alternative provides immediate procurement capability for high-volume requirements. For Amphenol ICC sourcing, the 46231-000LF provides 982 units in current inventory.
