3M 926141-01-20-EU Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-20-EU is a through-hole rectangular connector header with 20 positions at 2.54mm pitch, designed for board-to-board applications. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The connector features male pins with gold-plated contacts, solder termination, and push-pull fastening in an unshrouded configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 3M 926141-01-20-EU is determined by the following critical parameters that must remain consistent:

• Connector type: Header with breakaway capability
• Contact configuration: Male pins, 20 positions
• Pitch specification: 0.100" (2.54mm) mating pitch
• Mounting method: Through-hole solder termination
• Fastening mechanism: Push-pull engagement
• Electrical performance: Minimum 2.5A current rating
• Environmental compliance: UL94 V-0 flammability rating
• Moisture sensitivity: MSL 1 (Unlimited)

The two substitute parts listed below meet these core requirements while maintaining functional compatibility with the original 3M connector.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the original 3M 926141-01-20-EU.

The TE Connectivity 2-827064-0 maintains functional equivalence across all critical parameters. It operates across an extended temperature range (-65°C to 105°C) compared to the original part and carries RoHS compliance certification. The tin contact finish differs from the gold finish of the original, which may affect contact resistance characteristics in specific applications.

The Amphenol ICC 77311-132-20LF (BERGSTIK® series) provides the highest operating temperature range (-65°C to 125°C) and specifies a current rating of 3A per contact, exceeding the original 2.5A specification. This part maintains UL94 V-0 flammability rating and RoHS compliance. The contact finish is specified as gold or gold with GXT™ treatment, providing closer alignment with the original gold-plated specification. REACH compliance status is documented as affected.

Selection between these substitutes should be based on specific application requirements regarding contact finish preference, temperature operating range, and regulatory compliance documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-827064-0 directly replace the 3M 926141-01-20-EU in all applications?

A: The TE Connectivity part meets all core functional requirements including pitch, position count, mounting type, and termination method. The primary difference is the contact finish (tin versus gold). Applications sensitive to contact resistance or requiring specific contact finish specifications should evaluate this difference against application requirements.

Q: What is the significance of the extended temperature range in the Amphenol ICC 77311-132-20LF?

A: The Amphenol part operates from -65°C to 125°C, compared to the original -40°C to 105°C range. This extended range provides additional margin for applications operating in extreme temperature environments. However, this specification is only relevant if the application requires operation beyond the original temperature limits.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 3M original part packaging is not specified. The TE Connectivity 2-827064-0 is supplied in bulk packaging, while the Amphenol ICC 77311-132-20LF is supplied in bag packaging. Packaging format may affect handling, storage, and inventory management procedures.

Q: What does RoHS compliance mean for these connectors?

A: RoHS compliance indicates the parts meet Restriction of Hazardous Substances regulations, restricting lead and other hazardous materials. Both active substitute parts carry RoHS compliance certification, making them suitable for applications requiring regulatory compliance with RoHS directives.

Q: How do the contact materials differ between these parts?

A: The original 3M part uses copper alloy contacts, while the TE Connectivity substitute also uses copper alloy. The Amphenol ICC part uses phosphor bronze contacts. Phosphor bronze provides different mechanical and electrical properties, including improved spring characteristics and contact durability in high-cycle applications.

Q: Is the insulation material difference significant?

A: The original uses polycyclohexylenedimethylene terephthalate (PCT), the TE Connectivity substitute uses polybutylene terephthalate (PBT), and the Amphenol part uses thermoplastic material. All three materials provide UL94 V-0 or equivalent flammability performance. Material selection affects mechanical properties, temperature stability, and chemical resistance. Applications with specific environmental exposure requirements should verify material compatibility.
