TE Connectivity AMP Connectors 1571541-3 PLCC Socket Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1571541-3 is a 68-position PLCC socket designed for through-hole mounting applications. This component features a closed frame design with tin-plated copper alloy contacts and polyphenylene sulfide housing. The part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing procurement and system maintenance. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1571541-3 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• 68-position PLCC socket configuration (4 x 17 grid)
• 0.100" (2.54mm) mating pitch
• 0.100" (2.54mm) post pitch
• Tin contact finish on both mating and post surfaces
• 1 A current rating
• 30mOhm contact resistance
• Solder termination

Mechanical Compatibility Parameters:

• Through-hole mounting type
• Closed frame design
• UL94 V-0 flammability rating
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity

The Mill-Max Manufacturing Corp. 940-44-068-24-000000 meets all critical electrical and mechanical parameters required for direct substitution. Differences in contact material composition, housing polymer type, and post finish thickness do not affect functional compatibility within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max Manufacturing Corp. 940-44-068-24-000000 is a direct functional equivalent to the TE Connectivity 1571541-3. Both components satisfy identical electrical specifications, mechanical mounting requirements, and regulatory compliance standards. The Mill-Max part is currently in active production status with higher inventory availability (3683 pieces in stock versus 884 pieces for the obsolete TE Connectivity part).

Both components maintain ROHS3 compliance and UL94 V-0 flammability certification. The operating temperature range of the Mill-Max substitute (-55°C ~ 125°C) encompasses typical industrial and commercial applications. Selection between these parts should be based on procurement availability, lead time requirements, and existing supply chain relationships, as both components are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 940-44-068-24-000000 be used as a direct replacement for the TE Connectivity 1571541-3?

A: Yes. Both components share identical pin counts (68 positions), pitch specifications (0.100" mating and post), contact finishes (tin), current ratings (1 A), and contact resistance (30mOhm). Both feature closed frame designs, solder termination, and through-hole mounting. Electrical and mechanical compatibility is confirmed.

Q: What are the differences between these two parts?

A: The primary differences are non-functional for substitution purposes. The Mill-Max part uses beryllium copper for mating contacts and brass alloy for posts, compared to copper alloy in both positions for the TE Connectivity part. Housing materials differ (PCT polyester versus polyphenylene sulfide). Contact finish thicknesses vary slightly (150µin mating, 200µin post for Mill-Max versus 180µin for both on TE Connectivity). The Mill-Max part specifies a 0.130" termination post length and operating temperature range of -55°C ~ 125°C.

Q: Are there compliance or certification concerns with substitution?

A: No. Both components are ROHS3 compliant, carry UL94 V-0 flammability ratings, and maintain MSL 1 (Unlimited) moisture sensitivity levels. Both are classified as REACH Unaffected and carry EAR99 ECCN designation.

Q: What packaging format is the Mill-Max substitute supplied in?

A: The Mill-Max 940-44-068-24-000000 is supplied in tube packaging, compared to the standard packaging of the TE Connectivity part.

Q: Why is the TE Connectivity part listed as obsolete?

A: Product status reflects manufacturer discontinuation. The Mill-Max equivalent remains in active production, ensuring continued availability for new designs and replacement applications.
