TE Connectivity AMP Connectors 2-641260-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-641260-4 is an 8-position DIP socket with 0.3" (7.62mm) row spacing, gold-plated mating contacts, and through-hole solder termination. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design requirements and production continuity. The socket accommodates standard DIP integrated circuits with 0.100" (2.54mm) pitch and operates across the industrial temperature range of -55°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-641260-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 8 (2 x 4)
• Row spacing: 0.3" (7.62mm)
• Mating pitch: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination method: Solder

Acceptable Variation Parameters:

• Mating contact finish material (Gold or Tin acceptable for DIP socket applications)
• Post contact finish material (variations in plating composition permitted)
• Housing material composition (thermoplastic variants acceptable)
• Operating temperature upper limit (125°C or higher acceptable; lower limits require evaluation)
• Frame configuration (Closed or Open frame acceptable for DIP socket function)

Two substitute parts meet these criteria: the Mill-Max Manufacturing Corp. 116-93-308-41-006000 and the Assmann WSW Components A 08-LC-TT. Both maintain the core mechanical and electrical interface specifications required for DIP socket functionality.

Engineering Selection Recommendations

Mill-Max Manufacturing Corp. 116-93-308-41-006000

This substitute maintains full electrical and mechanical compatibility with the original 2-641260-4 across all critical interface parameters. The operating temperature range extends to 125°C, matching the original specification. The higher current rating of 3 A provides additional margin for applications requiring elevated current handling. However, this part carries RoHS non-compliant status and REACH Affected designation, presenting the same regulatory constraints as the original component. The post contact finish thickness of 200.0µin exceeds the original specification, providing enhanced durability for repeated insertion cycles.

Assmann WSW Components A 08-LC-TT

This substitute provides full mechanical compatibility and maintains the same contact resistance specification of 30mOhm. The component achieves ROHS3 compliance and REACH Unaffected status, offering regulatory advantages over the original part. The housing material (PBT) and flammability rating (UL94 V-0) match the original specifications. The operating temperature upper limit of 85°C is 40°C lower than the original specification, restricting use to applications operating below this threshold. The mating contact finish is Tin rather than Gold, and the post contact finish is Tin rather than Gold, representing a material composition change that remains functionally acceptable for standard DIP socket applications.

Selection between these substitutes depends on application-specific requirements: the Mill-Max part for applications requiring the full 125°C operating range and higher current capacity; the Assmann part for applications requiring regulatory compliance with RoHS3 and REACH standards and operating within the 85°C temperature limit.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 116-93-308-41-006000 be used as a direct replacement for the TE Connectivity 2-641260-4?

A: Yes. Both parts maintain identical row spacing (0.3"), mating pitch (0.100"), position count (8), and mounting configuration (through-hole solder). The operating temperature range matches at -55°C to 125°C. Differences in contact material composition and post finish thickness do not affect functional compatibility for standard DIP integrated circuit applications.

Q: What is the primary limitation of the Assmann A 08-LC-TT as a substitute?

A: The operating temperature upper limit is 85°C, compared to 125°C for the original part. Applications requiring operation above 85°C must use the Mill-Max substitute or the original part if available. All other mechanical and electrical parameters remain compatible.

Q: Does the change from Gold to Tin contact finish affect reliability?

A: The Assmann A 08-LC-TT uses Tin mating contact finish instead of Gold. Both finishes are standard for DIP socket applications and provide adequate contact performance for the specified current and resistance parameters. The choice between finishes depends on application-specific corrosion environment and contact cycling requirements.

Q: Are there packaging differences between these substitutes?

A: The TE Connectivity 2-641260-4 packaging is not specified in the provided data. Both the Mill-Max 116-93-308-41-006000 and Assmann A 08-LC-TT are supplied in Tube packaging, which is standard for DIP socket components.

Q: Which substitute offers better regulatory compliance?

A: The Assmann A 08-LC-TT achieves ROHS3 compliance and carries REACH Unaffected status. The Mill-Max 116-93-308-41-006000 maintains RoHS non-compliant status and REACH Affected designation, matching the original part's regulatory profile. Applications subject to RoHS3 or REACH restrictions should specify the Assmann component.

Q: What is the significance of the post contact finish thickness difference?

A: The Mill-Max part specifies 200.0µin (5.08µm) post contact finish thickness, compared to 15.0µin (0.38µm) for the original. The thicker finish on the Mill-Max component provides extended durability for applications involving repeated insertion and removal cycles, though both thicknesses are functionally adequate for standard DIP socket use.

Q: Can these substitutes be used interchangeably in the same circuit board design?

A: Mechanical interchangeability is confirmed for both substitutes. However, the Assmann part's 85°C temperature limit must be verified against the application's thermal requirements. Post length variations (0.120" original, 0.108" Mill-Max, 0.124" Assmann) are within acceptable tolerance for standard PCB through-hole designs but should be confirmed for specific board thickness and solder joint requirements.
