BBS-107-T-C Equivalent & Substitute Parts

Part Overview

The BBS-107-T-C is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This 7-position connector operates across the -55°C to 125°C temperature range and features a 0.100" (2.54mm) pitch with unshrouded, push-pull fastening. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are necessary when the main part becomes unavailable or when specific insulation height requirements differ for PCB layout constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BBS-107-T-C is determined by the following critical parameters that must remain constant across all equivalent parts:

• Manufacturer: Samtec Inc.
• Series: BBS
• Number of Positions: 7
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Operating Temperature Range: -55°C ~ 125°C
• Insulation Material: Polyester, Glass Filled
• Contact Shape: Circular

The substitute parts BBS-107-T-A and BBS-107-T-B meet all these criteria. Differences in insulation height and overall contact length do not affect electrical compatibility but may impact PCB layout and mating stack height considerations.

Parameter Comparison

Engineering Selection Recommendations

BBS-107-T-B is the primary substitute for BBS-107-T-C. Both parts maintain active product status, identical ROHS3 compliance, and equivalent electrical and mechanical specifications. The insulation height difference (0.335" vs 0.585") accommodates varying PCB layout requirements while maintaining full electrical compatibility.

BBS-107-T-A is a secondary substitute option. This part is discontinued at DiGi Electronics and carries MSL 1 (Unlimited) rating compared to Not Applicable for the main part. The significantly lower insulation height (0.211") makes this variant suitable only for applications with strict space constraints. The discontinued status limits long-term availability.

All three parts share identical contact pitch, mating contact length, post contact length, contact finish specifications, and operating temperature range, ensuring direct functional equivalence in board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: Can BBS-107-T-B replace BBS-107-T-C directly on existing PCBs?

A: Yes. Both parts share identical electrical specifications, contact pitch (0.100"), mating contact length (0.125"), and operating temperature range (-55°C ~ 125°C). The difference in insulation height (0.335" vs 0.585") does not affect electrical performance but may alter the mating stack height. PCB layout verification is necessary if mated stack height is a design constraint.

Q: What is the significance of the insulation height difference?

A: Insulation height determines the distance from the PCB surface to the top of the connector body. BBS-107-T-C has 0.585" insulation height, BBS-107-T-B has 0.335", and BBS-107-T-A has 0.211". These differences affect available space above the connector for cable routing or adjacent components. Electrical compatibility remains unchanged.

Q: Why is BBS-107-T-A listed as discontinued?

A: BBS-107-T-A is discontinued at DiGi Electronics, indicating limited availability through standard distribution channels. While electrically equivalent, this part should be considered only when BBS-107-T-B is unavailable and existing inventory can be sourced directly from the manufacturer.

Q: Are all three parts ROHS3 compliant?

A: Yes. BBS-107-T-C, BBS-107-T-A, and BBS-107-T-B are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in packaging between these parts?

A: BBS-107-T-C and BBS-107-T-B are supplied in Tube packaging. BBS-107-T-A packaging is not specified in available documentation.

Q: Do these connectors support different current or voltage ratings?

A: Current and voltage ratings are not specified for any of these parts in the provided documentation. Electrical performance is determined by contact material, finish, and geometry, which are identical across all three variants.
