926141-01-31-EU Equivalent & Substitute Parts

Part Overview

The 926141-01-31-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications with 31 positions at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated copper alloy contacts and is rated for 2.5A continuous current operation across a temperature range of -40°C to 105°C. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 926141-01-31-EU is determined by strict alignment with the following critical parameters:

• Position Count & Pitch: Substitute must have exactly 31 positions at 0.100" (2.54mm) mating pitch
• Contact Configuration: Male pin contacts required for board-to-board header applications
• Mounting & Termination: Through-hole solder termination mandatory
• Electrical Performance: Current rating must meet or exceed 2.5A; operating temperature range must encompass the original specification
• Mechanical Compatibility: Single-row, unshrouded configuration with push-pull fastening
• Regulatory Compliance: UL94 V-0 flammability rating required

The 68604-431HLF from Amphenol ICC (FCI) meets all substitution criteria. This connector maintains identical position count, pitch, mounting method, and termination type. While contact finish differs (tin versus gold) and operating temperature range is extended (-65°C ~ 125°C), the substitute provides equivalent electrical performance with higher current capacity (3A versus 2.5A) and maintains required safety certifications.

Parameter Comparison

Engineering Selection Recommendations

The 68604-431HLF is a direct functional equivalent for the obsolete 926141-01-31-EU. Selection of the substitute is supported by:

• Product Availability: The 68604-431HLF maintains active production status with 900 units in current inventory, ensuring supply chain continuity
• Regulatory Alignment: Both connectors carry UL94 V-0 flammability certification and share identical ECCN and HTSUS classifications
• Compliance Status: The 68604-431HLF is RoHS Compliant and REACH Unaffected, meeting modern environmental and safety standards
• Performance Margin: The substitute provides 3A current capacity against the original 2.5A requirement, offering operational headroom
• Temperature Range Extension: Operating temperature specification of -65°C ~ 125°C exceeds the original -40°C ~ 105°C range, supporting broader application environments

Contact finish and base material differences (tin-plated phosphor bronze versus gold-plated copper alloy) do not compromise electrical or mechanical compatibility for standard board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can the 68604-431HLF be used as a direct replacement in existing designs using the 926141-01-31-EU?

A: Yes. Both connectors share identical position count (31), mating pitch (0.100"), mounting method (through-hole), termination type (solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is maintained.

Q: What is the significance of the contact finish difference between gold and tin?

A: Contact finish affects corrosion resistance and contact resistance characteristics. The tin finish on the 68604-431HLF (100.0µin thickness) provides adequate protection for standard indoor and controlled environment applications. Gold finish on the original part offers enhanced corrosion resistance for demanding environments. Selection should consider the specific application environment.

Q: Does the higher current rating of the 68604-431HLF (3A vs 2.5A) affect compatibility?

A: No. Higher current capacity is a performance advantage and does not create compatibility issues. The substitute can safely handle applications designed for the original 2.5A specification.

Q: Are there packaging differences between these connectors?

A: The 926141-01-31-EU packaging information is not specified in available data. The 68604-431HLF is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the impact of the extended operating temperature range of the 68604-431HLF?

A: The substitute's -65°C ~ 125°C range encompasses the original -40°C ~ 105°C specification. This extension provides design flexibility for applications requiring operation outside the original temperature envelope without compromising performance within the original range.

Q: Are both connectors classified as moisture sensitive?

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage, handling, or assembly.
