926141-01-34-EU Equivalent & Substitute Parts

Part Overview

The 926141-01-34-EU is a rectangular connector header manufactured by 3M, designed for through-hole board-to-board applications with 34 positions at 0.100" (2.54mm) pitch. This connector features a breakaway design with unshrouded configuration and solder termination. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 926141-01-34-EU is determined by strict equivalence across the following critical parameters:

• Connector position count: 34 positions (non-negotiable)
• Pitch specification: 0.100" (2.54mm) mating pitch (non-negotiable)
• Contact type: Male pin configuration
• Mounting method: Through-hole solder termination
• Board interface style: Board-to-board, unshrouded, single-row layout
• Fastening mechanism: Push-pull retention
• Contact geometry: Square contact shape
• Electrical performance: Current rating and operating temperature range within acceptable industrial standards
• Regulatory compliance: UL94 V-0 flammability rating and MSL classification

The substitute part 68604-434HLF meets these core substitution criteria while maintaining mechanical and electrical compatibility with the original 926141-01-34-EU specification.

Parameter Comparison

Engineering Selection Recommendations

The 68604-434HLF (Amphenol ICC BERGSTIK® II series) is a direct functional substitute for the obsolete 926141-01-34-EU. Both connectors share identical mechanical interfaces, position counts, pitch specifications, and mounting configurations required for board-to-board connectivity.

The substitute part offers enhanced performance characteristics: extended operating temperature range (-65°C to 125°C versus -40°C to 105°C), increased current rating (3A versus 2.5A), and active product status ensuring ongoing availability and supply chain continuity. Both parts maintain UL94 V-0 flammability compliance and MSL 1 moisture sensitivity classification.

Contact finish differences (gold on the original versus tin on the substitute) and contact material variations (copper alloy versus phosphor bronze) are within acceptable substitution parameters for standard board-to-board applications. The substitute's tin finish with increased thickness (100.0µin) provides equivalent corrosion resistance and contact reliability for solder-terminated connections.

The 68604-434HLF is suitable for direct replacement in legacy system maintenance and new designs requiring 34-position 2.54mm pitch header connectors with push-pull retention and through-hole solder termination.

Frequently Asked Questions (FAQ)

Q: Can the 68604-434HLF directly replace the 926141-01-34-EU in existing PCB designs?

A: Yes. Both connectors share identical pitch (0.100"/2.54mm), position count (34), contact type (male pin), mounting method (through-hole solder), and board interface style (unshrouded, single-row, board-to-board). PCB footprints designed for the 926141-01-34-EU are mechanically compatible with the 68604-434HLF.

Q: What are the differences in contact finish between these two connectors?

A: The 926141-01-34-EU features gold-plated contacts (10.0µin thickness) on copper alloy base material. The 68604-434HLF uses tin-plated contacts (100.0µin thickness) on phosphor bronze base material. Both finishes provide adequate corrosion resistance and electrical conductivity for solder-terminated applications. Tin plating with greater thickness offers enhanced durability in high-cycle mating environments.

Q: Does the substitute part support the same current and temperature specifications?

A: The 68604-434HLF exceeds the original specifications. It supports 3A current rating (versus 2.5A) and operates across -65°C to 125°C (versus -40°C to 105°C). These enhanced ratings ensure compatibility with the original design requirements and provide additional operational margin.

Q: Are both connectors RoHS and REACH compliant?

A: The 926141-01-34-EU product status is listed as obsolete with no RoHS/REACH information provided. The 68604-434HLF is confirmed RoHS Compliant and REACH Affected, meeting current regulatory requirements for electronic component procurement.

Q: What is the packaging difference between these parts?

A: The 926141-01-34-EU packaging specification is not provided. The 68604-434HLF is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any mechanical dimension differences that could affect assembly?

A: Contact length specifications differ slightly. The 926141-01-34-EU has mating contact length of 0.428" (10.87mm) and post length of 0.100" (2.54mm), yielding overall contact length of 0.628" (15.95mm). The 68604-434HLF has mating contact length of 0.380" (9.65mm) and post length of 0.120" (3.05mm), yielding overall contact length of 0.600" (15.24mm). These dimensional variations remain within standard tolerance ranges for 2.54mm pitch header connectors and do not affect PCB footprint compatibility or mating interface performance.
