926141-01-26-EU Equivalent & Substitute Parts

Part Overview

The 3M 926141-01-26-EU is a rectangular connector header designed for through-hole mounting applications. This 26-position, single-row connector operates at 0.100" (2.54mm) pitch and is rated for 2.5A continuous current across an operating temperature range of -40°C to 105°C. The connector features gold-plated copper alloy contacts with push-pull fastening and is constructed from UL94 V-0 rated polycyclohexylenedimethylene terephthalate (PCT) insulation material.

The 926141-01-26-EU is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this connector specification.

Substitute Part Grouping Explanation

Substitution eligibility for the 926141-01-26-EU is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pin contacts
Position Count & Pitch: 26 positions at 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination
Fastening Mechanism: Push-pull fastening type
Electrical Performance: Current rating and operating temperature range
Physical Compatibility: Single-row, unshrouded configuration with square contact shape
Regulatory Compliance: UL94 V-0 flammability rating

The Amphenol ICC (FCI) 68604-426HLF meets these core substitution criteria. Both connectors share identical position count, pitch, mounting method, termination type, fastening mechanism, and regulatory compliance classification.

Engineering Selection Recommendations

The 68604-426HLF serves as a direct functional substitute for the obsolete 926141-01-26-EU. Both connectors maintain identical mechanical and electrical interface specifications, ensuring PCB-level compatibility without design modification.

The 68604-426HLF offers extended operating temperature range (-65°C to 125°C versus -40°C to 105°C) and higher current rating (3A versus 2.5A), providing performance margin for demanding applications. The connector is classified as active product status with RoHS compliance and REACH affected designation, supporting modern supply chain and regulatory requirements.

Contact finish differences (tin versus gold) and contact material variations (phosphor bronze versus copper alloy) do not preclude substitution for standard board-to-board interconnect applications. The tin finish and phosphor bronze construction of the 68604-426HLF are established materials meeting equivalent electrical and mechanical performance standards.

Frequently Asked Questions (FAQ)

Q: Can the 68604-426HLF directly replace the 926141-01-26-EU without PCB modification?

A: Yes. Both connectors share identical 26-position, 0.100" (2.54mm) pitch configuration with single-row, through-hole solder termination. PCB footprints are mechanically compatible.

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

A: The 926141-01-26-EU uses gold-plated contacts (10.0µin thickness), while the 68604-426HLF uses tin-plated contacts (100.0µin thickness). Both finishes provide adequate corrosion resistance and electrical conductivity for standard interconnect applications.

Q: Does the higher current rating of the 68604-426HLF affect compatibility?

A: No. The 3A rating of the 68604-426HLF exceeds the 2.5A requirement of the 926141-01-26-EU, providing additional performance margin. Applications designed for 2.5A operation remain fully compatible.

Q: Are there temperature range considerations for substitution?

A: The 68604-426HLF operates across -65°C to 125°C, exceeding the original -40°C to 105°C range. Applications within the original temperature specification are fully supported by the substitute part.

Q: What is the packaging difference between these parts?

A: The 926141-01-26-EU is supplied without specified packaging designation. The 68604-426HLF is packaged in bags. This difference does not affect connector performance or compatibility.

Q: Are both connectors RoHS compliant?

A: The 926141-01-26-EU RoHS status is not specified in the provided data. The 68604-426HLF is RoHS compliant, supporting applications with RoHS requirements.
