68464-172 Equivalent & Substitute Parts

Part Overview

The 68464-172 is a rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® II series. This through-hole connector features 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

Substitution for the 68464-172 is determined by the following critical parameters:

Connector Type & Contact Type: Header with male pins
Position Count & Row Configuration: 72 positions in 2 rows
Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
Mounting & Termination: Through-hole solder termination
Application Style: Board-to-board connectivity

The 68464-172HLF is a direct equivalent from the same manufacturer (Amphenol ICC), differing only in packaging (bulk vs. standard) and RoHS compliance status. The Samtec BBD-136-G-C and BBD-136-T-C parts are manufacturer-recommended alternatives that meet the core electrical and mechanical requirements, though they introduce variations in contact geometry, insulation height, and operating temperature range.

Engineering Selection Recommendations

68464-172HLF is the primary substitute for the obsolete 68464-172. Both parts are from Amphenol ICC and share identical electrical and mechanical specifications. The 68464-172HLF is currently in active production status and offers RoHS compliance, making it the preferred choice for new designs and ongoing production support.

BBD-136-G-C and BBD-136-T-C (Samtec Inc.) are manufacturer-recommended alternatives that provide functional equivalence for board-to-board 72-position header applications. These parts maintain the critical 0.100" pitch and 2-row configuration. Key differences include:

Contact geometry: Circular pins versus square pins in the original design
Insulation height: Significantly taller (0.585" vs. 0.100"), affecting PCB layout compatibility
Operating temperature range: Slightly narrower (-55°C to 125°C vs. -65°C to 130°C)
Contact finish options: Gold (BBD-136-G-C) or Tin (BBD-136-T-C)

Both Samtec alternatives carry ROHS3 compliance and are actively produced. Selection between BBD-136-G-C and BBD-136-T-C depends on contact finish requirements for your application.

Frequently Asked Questions (FAQ)

Q: Can 68464-172HLF be used as a direct replacement for 68464-172?

A: Yes. The 68464-172HLF is electrically and mechanically identical to the 68464-172, with the primary differences being packaging format (bulk) and RoHS compliance status. Both parts are from Amphenol ICC and share the same BERGSTIK® II series specifications.

Q: What are the main differences between Amphenol and Samtec alternatives?

A: The Amphenol 68464-172HLF maintains identical contact geometry and insulation height to the original 68464-172. The Samtec BBD-136 series introduces different contact shapes (circular vs. square) and significantly taller insulation height (0.585" vs. 0.100"), which may affect PCB layout and mating connector compatibility. Verify mechanical fit before substitution.

Q: Are the Samtec BBD-136-G-C and BBD-136-T-C interchangeable?

A: Both Samtec parts are mechanically and electrically equivalent, differing only in mating contact finish: BBD-136-G-C uses gold plating, while BBD-136-T-C uses tin plating. Selection depends on your application's contact finish requirements and compatibility with mating connectors.

Q: What is the impact of the narrower operating temperature range in Samtec alternatives?

A: The Samtec BBD-136 series operates from -55°C to 125°C, compared to -65°C to 130°C for the Amphenol parts. If your application requires operation below -55°C or above 125°C, the Amphenol 68464-172HLF is the appropriate choice.

Q: How does the increased insulation height of Samtec parts affect compatibility?

A: The Samtec BBD-136 series has an insulation height of 0.585" (14.86mm) versus 0.100" (2.54mm) for the Amphenol parts. This significantly taller profile may require PCB layout modifications and affects compatibility with existing mating connectors. Verify mechanical clearance and mating connector specifications before design implementation.

Q: Are all substitute parts RoHS compliant?

A: The 68464-172 is RoHS non-compliant. The 68464-172HLF is RoHS Compliant, and both Samtec alternatives (BBD-136-G-C and BBD-136-T-C) are ROHS3 Compliant. For applications requiring RoHS compliance, use 68464-172HLF or the Samtec alternatives.
