Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 926141-01-28-EU is determined by the following critical parameters:

• Connector Type & Configuration: Header with 28 positions, single row, 0.100" (2.54mm) pitch
• Contact Characteristics: Male pin, square contact shape, solder termination
• Mounting & Fastening: Through-hole mounting with push-pull fastening mechanism
• Environmental Compliance: UL94 V-0 flammability rating, MSL 1 classification
• Electrical Performance: Current rating and operating temperature range

The substitute part 68604-428HLF meets these core substitution criteria. Both connectors share identical pitch spacing, position count, row configuration, contact type, mounting method, and fastening mechanism. Both maintain UL94 V-0 compliance and MSL 1 classification, ensuring compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

The 68604-428HLF (Amphenol ICC BERGSTIK® II series) is a direct functional substitute for the obsolete 926141-01-28-EU. Both connectors satisfy identical mechanical and electrical interface requirements for 28-position, 2.54mm pitch board-to-board applications.

Product Status Consideration: The 926141-01-28-EU is obsolete, while the 68604-428HLF maintains active production status with documented inventory availability. This ensures long-term procurement viability and supply chain continuity.

Compliance & Certification: Both parts maintain UL94 V-0 flammability rating and MSL 1 classification. The 68604-428HLF carries RoHS compliance and REACH affected status documentation, meeting modern regulatory requirements.

Performance Envelope: The 68604-428HLF operates across a wider temperature range (-65°C ~ 125°C versus -40°C ~ 105°C) and supports higher current capacity (3A versus 2.5A), providing enhanced performance margins for equivalent or more demanding applications.

Contact Finish Differences: The original part features gold plating (10.0µin) on both mating and post contacts, while the substitute uses tin plating (100.0µin on mating surface). Both finishes are suitable for solder termination and push-pull connector applications. Contact material differs (copper alloy versus phosphor bronze), but both materials are standard for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the 68604-428HLF directly replace the 926141-01-28-EU in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100"), position count (28), row configuration (1), contact type (male pin), mounting method (through-hole), and fastening mechanism (push-pull). The mechanical and electrical interfaces are equivalent.

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

A: The 926141-01-28-EU uses gold plating (10.0µin thickness) on mating and post contacts. The 68604-428HLF uses tin plating (100.0µin on mating surface). Both finishes are compatible with solder termination and standard PCB assembly processes. Gold plating provides enhanced corrosion resistance; tin plating offers cost efficiency and is widely used in industrial applications.

Q: Does the wider operating temperature range of the 68604-428HLF affect compatibility?

A: No. The substitute's extended temperature range (-65°C ~ 125°C) encompasses the original part's range (-40°C ~ 105°C). This provides additional operational margin without affecting compatibility in applications within the original temperature specification.

Q: Are there packaging differences between these connectors?

A: The 926141-01-28-EU packaging is not specified in available documentation. The 68604-428HLF is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the higher current rating on the substitute part?

A: The 68604-428HLF supports 3A current capacity compared to the original part's 2.5A rating. This provides additional electrical margin and allows use in applications requiring higher current handling without derating.

Q: Are both parts RoHS compliant?

A: The 926141-01-28-EU RoHS status is not specified. The 68604-428HLF is explicitly RoHS compliant and REACH affected, meeting current environmental and regulatory standards for electronic components.
