Amphenol ICC 78286-172H Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78286-172H is a rectangular connector header featuring 72 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated connector is designed for board-to-board applications and is classified as Active product status. The BERGSTIK® II series connector uses unshrouded male pin contacts with gold or GXT™ finish on phosphor bronze material. Finding equivalent substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 78286-172H are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Criteria:

• Number of Positions: 72
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Style: Board to Board (or Board to Board or Cable)
• Shrouding: Unshrouded

All three substitute parts (3-826632-6, BBD-136-G-B, BBD-136-T-B) meet these core compatibility requirements. Variations in contact material, contact finish composition, insulation material, and operating temperature ranges do not prevent functional substitution when the above parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

3-826632-6 (TE Connectivity AMPMODU Mod II): This substitute offers ROHS3 compliance, addressing regulatory requirements not met by the original 78286-172H. The TE Connectivity part features a breakaway connector option, providing additional application flexibility. Operating temperature range of -65°C to 105°C and 5A current rating are specified. Insulation material is PBT with green color coding. This part is suitable for applications requiring RoHS3 compliance and standard operating conditions.

BBD-136-G-B (Samtec BBD Series, Gold Finish): This substitute maintains ROHS3 compliance and extends the operating temperature range to -55°C to 125°C. The gold contact finish on the mating surface aligns with the original part's gold finish specification. Insulation material is polyester with glass fill. This part is appropriate for applications requiring extended temperature performance and gold contact finish consistency.

BBD-136-T-B (Samtec BBD Series, Tin Finish): This substitute also provides ROHS3 compliance and the extended -55°C to 125°C operating temperature range. The tin contact finish on the mating surface differs from the original gold specification. Insulation material is polyester with glass fill. This part is suitable for cost-sensitive applications where tin finish is acceptable and extended temperature performance is required.

All three substitutes maintain Active product status and MSL 1 (Unlimited) moisture sensitivity level, ensuring long-term availability and handling consistency with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 3-826632-6 be used as a direct replacement for the 78286-172H?

A: Yes. Both connectors share identical core specifications: 72 positions, 2 rows, 0.100" pitch, through-hole solder termination, and push-pull fastening. The 3-826632-6 offers the additional benefit of ROHS3 compliance and a breakaway connector option. Differences in contact material (brass vs. phosphor bronze) and insulation material (PBT vs. unspecified) do not prevent functional substitution.

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

A: The primary difference is the contact finish on the mating surface. BBD-136-G-B uses gold finish, while BBD-136-T-B uses tin finish. Both parts are otherwise identical in position count, pitch, row spacing, mounting type, and termination method. Selection between these two depends on application requirements for contact finish material and cost considerations.

Q: Does the change in contact shape from square to circular affect compatibility?

A: Contact shape does not affect mating compatibility when pitch and row spacing remain identical at 0.100" (2.54mm). The Samtec BBD series parts (BBD-136-G-B and BBD-136-T-B) use circular contacts while the original uses square contacts. Both geometries accommodate the same 0.100" pitch spacing and maintain electrical and mechanical function.

Q: Are there packaging differences between these substitutes?

A: Yes. The original 78286-172H and 3-826632-6 are supplied in bulk packaging. The Samtec parts (BBD-136-G-B and BBD-136-T-B) are supplied in tube packaging. Packaging format does not affect connector function but may influence handling, storage, and procurement workflows.

Q: Which substitute is best for RoHS3 compliance requirements?

A: All three substitutes (3-826632-6, BBD-136-G-B, BBD-136-T-B) are ROHS3 compliant. The original 78286-172H is RoHS non-compliant. Selection among the three compliant options depends on operating temperature requirements, contact finish preference, and packaging needs.

Q: What is the operating temperature range for the original 78286-172H?

A: The operating temperature range for the 78286-172H is not specified in the provided data. The 3-826632-6 operates from -65°C to 105°C, while both Samtec parts operate from -55°C to 125°C. Application-specific temperature requirements should guide substitute selection.

Q: Can the 3-826632-6 breakaway feature be ignored if not needed?

A: Yes. The breakaway feature is an additional capability of the 3-826632-6 that does not affect its function as a standard 72-position header connector. Applications that do not require breakaway functionality can use this part without impact to electrical or mechanical performance.
