Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 926141-01-32-EU is determined by the following critical parameters:

• Connector Type: Header configuration for board-to-board connectivity
• Contact Type: Male pin contacts
• Number of Positions: 32-position configuration
• Pitch - Mating: 0.100" (2.54mm) standard spacing
• Mounting Type: Through-hole PCB assembly
• Termination: Solder connection method
• Shrouding: Unsshrouded design
• Number of Rows: Single row configuration

The substitute part 68604-432HLF meets all critical substitution criteria. This Amphenol ICC (FCI) connector maintains identical pitch, position count, mounting method, and termination approach, ensuring mechanical and electrical compatibility in applications previously designed for the 3M 926141-01-32-EU.

Parameter Comparison

Engineering Selection Recommendations

The 68604-432HLF (Amphenol ICC BERGSTIK® II series) is the qualified substitute for the obsolete 926141-01-32-EU. Selection is based on the following engineering factors:

Product Status: The 926141-01-32-EU is obsolete, while the 68604-432HLF maintains active production status, ensuring long-term component availability and supply chain continuity.

Compliance & Certifications: Both connectors meet UL94 V-0 flammability requirements and share identical ECCN classification (EAR99), maintaining regulatory compliance across applications.

Electrical Performance: The 68604-432HLF provides enhanced current rating (3A versus 2.5A) and extended operating temperature range (-65°C ~ 125°C versus -40°C ~ 105°C), offering improved performance margins for demanding applications.

Mechanical Compatibility: Identical pitch (0.100"), position count (32), mounting method (through-hole), and termination approach (solder) ensure direct PCB footprint compatibility without design modification.

Contact Finish Differences: The 926141-01-32-EU features gold plating (10.0µin), while the 68604-432HLF uses tin plating (100.0µin). Both finishes provide adequate corrosion resistance for standard industrial applications; gold plating may be preferred for high-reliability or low-signal-level applications.

Frequently Asked Questions (FAQ)

Q: Can the 68604-432HLF directly replace the 926141-01-32-EU without PCB modification?

A: Yes. Both connectors share identical pitch (0.100"), position count (32), mounting type (through-hole), and footprint dimensions. No PCB redesign is required.

Q: What is the difference between the gold and tin contact finishes?

A: The 926141-01-32-EU uses gold plating (10.0µin thickness) on copper alloy contacts, while the 68604-432HLF uses tin plating (100.0µin thickness) on phosphor bronze contacts. Gold provides superior corrosion resistance and lower contact resistance, particularly beneficial in low-signal applications. Tin plating is cost-effective and suitable for standard signal and power distribution applications.

Q: Does the extended operating temperature range of the 68604-432HLF affect compatibility?

A: No. The 68604-432HLF operating range (-65°C ~ 125°C) encompasses the original specification (-40°C ~ 105°C). This represents an improvement, not a limitation.

Q: Are there compliance or regulatory differences between these connectors?

A: Both connectors share identical ECCN classification (EAR99), HTSUS code (8536.69.4040), and UL94 V-0 flammability rating. The 68604-432HLF is RoHS Compliant and REACH Unaffected, meeting current environmental standards.

Q: What is the significance of the current rating difference (2.5A versus 3A)?

A: The 68604-432HLF provides 20% higher current capacity. For applications operating at or near the original 2.5A specification, the substitute offers improved thermal margin and reduced contact resistance heating.

Q: How do the contact length specifications compare?

A: The 926141-01-32-EU has mating contact length of 0.428" (10.87mm) and post length of 0.100" (2.54mm). The 68604-432HLF has mating contact length of 0.380" (9.65mm) and post length of 0.120" (3.05mm). Overall contact length differs slightly (15.95mm versus 15.24mm), but both are compatible with standard 0.100" pitch mating connectors.
