BBD-136-G-D Equivalent & Substitute Parts

Part Overview

The BBD-136-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This vertical 72-position connector operates across the industrial temperature range of -55°C to 125°C and maintains Active product status. Substitute parts are identified to provide design flexibility when the primary part number is unavailable or when specific mechanical envelope requirements necessitate alternative configurations within the same connector family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the BBD-136 family is determined by the following invariant parameters that must remain constant across all equivalent parts:

• Manufacturer: Samtec Inc.
• Series: BBD
• 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
• Contact Finish - Mating: Gold
• Contact Finish - Post: Nickel
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts BBD-136-G-A and BBD-136-G-B differ only in mechanical envelope dimensions (Overall Contact Length and Insulation Height), which are determined by the suffix designation. These variations accommodate different PCB stack-up requirements while maintaining full electrical and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance with identical electrical specifications and operating temperature ranges. Selection between BBD-136-G-D, BBD-136-G-A, and BBD-136-G-B is determined solely by mechanical envelope requirements:

BBD-136-G-D accommodates applications requiring maximum contact extension (1.085" overall length, 0.835" insulation height) for deeper PCB stack-ups or applications with greater mating depth requirements.

BBD-136-G-A provides the most compact profile (0.460" overall length, 0.211" insulation height) for space-constrained designs or shallow PCB configurations.

BBD-136-G-B offers an intermediate envelope (0.585" overall length, 0.335" insulation height) for standard PCB stack-up applications.

All parts share identical contact pitch, row spacing, contact materials, finishes, and compliance certifications, ensuring direct mechanical and electrical interchangeability within the specified envelope constraints.

Frequently Asked Questions (FAQ)

Q: Are BBD-136-G-D, BBD-136-G-A, and BBD-136-G-B electrically identical?

A: Yes. All three parts share identical electrical specifications, contact pitch (0.100"), row spacing (0.100"), contact materials, finishes, and operating temperature range (-55°C to 125°C). Differences are limited to mechanical envelope dimensions.

Q: What determines which variant to select?

A: Selection is based on PCB stack-up depth and available mating space. BBD-136-G-D requires 1.085" contact extension, BBD-136-G-B requires 0.585", and BBD-136-G-A requires 0.460". Verify your application's mechanical constraints before part selection.

Q: Can these parts be used interchangeably on the same PCB?

A: No. While electrically compatible, the different overall contact lengths and insulation heights mean each variant is designed for specific PCB configurations. Using an incorrect variant may result in improper mating depth or contact engagement.

Q: Are all variants ROHS3 compliant?

A: Yes. BBD-136-G-D, BBD-136-G-A, and BBD-136-G-B are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the pitch specification for these connectors?

A: All variants feature 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing in a 2-row, 72-position configuration.
