Amphenol ICC 68439-472 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68439-472 is a rectangular connector header from the BERGSTIK® II series, designed for through-hole board-to-board applications with 72 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The part features a 2-row configuration with unshrouded, push-pull fastening and solder termination suitable for standard PCB assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 68439-472 is based on the following critical parameters that must remain consistent:

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

The substitute parts BBD-136-G-C and BBD-136-T-C from Samtec Inc. meet these core functional requirements. Both are active-status components from the BBD series, providing direct functional equivalence for the obsolete 68439-472. The primary differences lie in contact geometry (circular vs. square), contact finish specifications, and insulation material composition, which do not affect the fundamental electrical and mechanical interface compatibility for standard board-to-board interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Both BBD-136-G-C and BBD-136-T-C are recommended as primary alternatives to the obsolete 68439-472. Both substitute parts carry active product status and ROHS3 compliance, supporting modern regulatory requirements and long-term supply chain availability.

BBD-136-G-C Selection: This variant features gold mating contact finish, providing enhanced corrosion resistance and contact reliability in applications requiring extended shelf life or exposure to variable environmental conditions.

BBD-136-T-C Selection: This variant features tin mating contact finish, maintaining cost parity with the original 68439-472 specification while delivering active product status and ROHS3 compliance.

Both Samtec substitutes provide specified operating temperature range (-55°C ~ 125°C), which exceeds the thermal requirements of the original component. The transition from square to circular contact geometry does not affect functional compatibility for standard board-to-board interconnection applications at the specified 0.100" (2.54mm) pitch.

Frequently Asked Questions (FAQ)

Q: Can BBD-136-G-C and BBD-136-T-C be used interchangeably with the 68439-472?

A: Yes. Both substitute parts maintain identical position count (72), row configuration (2 rows), mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). The core board-to-board interface is functionally equivalent.

Q: What is the difference between BBD-136-G-C and BBD-136-T-C?

A: The primary difference is the mating contact finish. BBD-136-G-C uses gold plating for enhanced corrosion resistance, while BBD-136-T-C uses tin plating. Both maintain identical electrical and mechanical specifications for the 72-position, 2.54mm pitch header configuration.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both BBD-136-G-C and BBD-136-T-C are ROHS3 compliant, whereas the original 68439-472 is RoHS non-compliant. This compliance upgrade supports modern manufacturing and regulatory requirements.

Q: What is the packaging format for the substitute parts?

A: Both BBD-136-G-C and BBD-136-T-C are supplied in tube packaging, suitable for standard component handling and automated assembly processes.

Q: Are there any dimensional differences that affect PCB layout?

A: The overall contact length differs between the original and substitutes (0.720" for 68439-472 versus 0.835" for both BBD variants), and insulation height differs (0.100" versus 0.585"). These dimensional changes require PCB footprint verification during design transition, though the mating pitch and row spacing remain identical.

Q: What is the operating temperature range for the substitute parts?

A: Both BBD-136-G-C and BBD-136-T-C operate across -55°C to 125°C, providing a defined thermal specification not listed for the original 68439-472.
