Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 78286-272H are qualified based on the following critical parameters that determine functional compatibility:

Core Matching 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 substitute parts listed meet these core electrical and mechanical parameters. Variations in contact length, insulation height, contact material, and finish specifications are secondary parameters that do not prevent functional substitution in standard applications.

Engineering Selection Recommendations

Primary Recommendation: 3-826632-6 (TE Connectivity AMPMODU Mod II)

The 3-826632-6 is the preferred substitute due to ROHS3 compliance status, active product status, and extended operating temperature range (-65°C to 105°C). This part provides the highest regulatory alignment for new designs and ongoing production applications.

Secondary Recommendations:

The 2372-6121-TG (3M 2300 series) is suitable for applications where RoHS non-compliance is acceptable. This part maintains active status and provides specified current rating (3A) and operating temperature range (-55°C to 105°C).

The BBD-136-G-B and BBD-136-T-B (Samtec BBD series) are active alternatives with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). These parts feature circular contact geometry and higher insulation height compared to the original part, which may require mechanical verification in space-constrained applications.

Compliance Considerations:

For applications requiring RoHS3 compliance, select from 3-826632-6, BBD-136-G-B, or BBD-136-T-B. The original 78286-272H and 2372-6121-TG do not meet RoHS3 requirements.

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts interchangeably with the 78286-272H?

A: Yes, all listed substitute parts meet the core electrical and mechanical parameters: 72 positions, 2 rows, 2.54mm pitch, through-hole solder termination, and push-pull fastening. Physical board layout compatibility should be verified due to variations in contact length and insulation height.

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

A: Both parts are functionally equivalent with identical electrical specifications. The primary difference is contact finish: BBD-136-G-B features gold mating finish, while BBD-136-T-B features tin mating finish. Contact finish selection depends on application requirements and solderability preferences.

Q: Why is the 3-826632-6 recommended as the primary substitute?

A: The 3-826632-6 offers ROHS3 compliance, active product status, and extended operating temperature range (-65°C to 105°C), making it suitable for both legacy applications and new designs requiring regulatory compliance.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 78286-272H is supplied in bulk packaging. The 3M 2372-6121-TG is supplied in bulk. The TE Connectivity 3-826632-6 is supplied in bulk. The Samtec BBD-136-G-B and BBD-136-T-B are supplied in tube packaging. Packaging format should be confirmed with procurement requirements.

Q: What is the significance of contact shape differences (square vs. circular)?

A: The original 78286-272H and most substitutes feature square contact geometry. The Samtec BBD series uses circular contacts. Contact shape does not affect electrical performance but may impact mechanical fit in connector housings. Verify mechanical compatibility with mating connectors before substitution.

Q: Can I substitute the 78286-272H in existing designs without PCB modification?

A: Core electrical compatibility is maintained across all substitutes. However, variations in contact length (ranging from 0.125" to 0.264"), insulation height (0.100" to 0.335"), and overall contact length (0.450" to 0.585") may require mechanical verification. Physical board layout and clearance should be confirmed before implementation.
