Amphenol ICC 68734-572 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68734-572 is a vertical through-hole rectangular connector header with 72 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® II series connector is designed for board-to-board applications with solder termination and push-pull fastening. The part is currently active in production with 750 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68734-572 is determined by strict equivalence in the following critical parameters:

• 72 positions in 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Male pin contact type
• Through-hole solder termination
• Push-pull fastening mechanism
• Board-to-board or board-to-cable connectivity
• Unshrouded design
• UL94 V-0 flammability rating

The four identified substitute parts meet these core requirements. Variations in contact geometry (square vs. circular), contact material composition, contact finish specifications, insulation material, and operating temperature ranges do not preclude substitution when the primary electrical and mechanical interface parameters are equivalent.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with unlimited moisture sensitivity ratings and equivalent core interface specifications. Selection between substitutes depends on compliance requirements and operational constraints:

TE Connectivity 3-826632-6 and 3-826925-6 are ROHS3 compliant alternatives to the RoHS non-compliant 68734-572. Both support board-to-board or cable connectivity and operate across -65°C to 105°C. The 3-826632-6 features gold mating contact finish with brass contact material, while the 3-826925-6 uses tin mating finish with copper alloy contact material. Both are rated for 5A current.

Samtec BBD-136-G-B and BBD-136-T-B are ROHS3 compliant alternatives with extended operating temperature range (-55°C to 125°C) and circular contact geometry. The BBD-136-G-B uses gold mating finish, while the BBD-136-T-B uses tin mating finish. Both feature nickel post finish and polyester glass-filled insulation.

For applications requiring RoHS3 compliance, TE Connectivity or Samtec options are appropriate. For applications with elevated temperature requirements, Samtec BBD series supports operation to 125°C. For applications requiring specific contact finish characteristics, gold-finished variants (3-826632-6, BBD-136-G-B) or tin-finished variants (3-826925-6, BBD-136-T-B) are available.

Frequently Asked Questions (FAQ)

Q: Can the 68734-572 be directly replaced with any of these substitute parts?

A: Yes. All four substitute parts maintain equivalent 72-position, 2-row configuration at 0.100" (2.54mm) pitch with male pin contacts, through-hole solder termination, and push-pull fastening. The primary interface parameters are identical, enabling direct substitution in board-to-board applications.

Q: What are the differences between the TE Connectivity and Samtec options?

A: TE Connectivity AMPMODU Mod II series (3-826632-6, 3-826925-6) support both board-to-board and cable connectivity with square contact geometry. Samtec BBD series (BBD-136-G-B, BBD-136-T-B) are board-to-board only with circular contact geometry. Samtec parts operate to 125°C versus 105°C for TE Connectivity parts.

Q: Does contact finish affect substitution compatibility?

A: Contact finish (gold vs. tin) does not affect mechanical or electrical interface compatibility. Selection between gold and tin finishes depends on application-specific corrosion resistance, solderability, or contact resistance requirements.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 3-826632-6 and 3-826925-6 are ROHS3 compliant. The Samtec BBD-136-G-B and BBD-136-T-B are ROHS3 compliant. The original 68734-572 is RoHS non-compliant. For applications requiring RoHS compliance, any of the four substitutes are appropriate.

Q: What is the difference between the two Samtec variants (BBD-136-G-B vs. BBD-136-T-B)?

A: Both parts are identical except for mating contact finish. The BBD-136-G-B uses gold finish, while the BBD-136-T-B uses tin finish. Both support identical operating temperature range (-55°C to 125°C) and current handling.

Q: Can these parts be used interchangeably in the same assembly?

A: Yes, within the constraints of your application requirements. All parts maintain the same 72-position, 2-row 0.100" pitch interface. Verify that your PCB layout and mating connector are compatible with the selected substitute's contact geometry (square vs. circular) and insulation height specifications.
