TFM-105-12-S-D-P Equivalent & Substitute Parts

Part Overview

The TFM-105-12-S-D-P is a surface mount rectangular connector header manufactured by Samtec Inc. in the Tiger Eye™ TFM series. This 10-position, 2-row connector with 0.050" (1.27mm) pitch is designed for board-to-board or cable applications with shrouded 4-wall construction and push-pull fastening. The part is active in production and widely stocked, with 992 units available in inventory. Alternative components may be required due to application-specific mounting constraints, thermal requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The SBH41-NBPB-D05-ST-BK from Sullins Connector Solutions is identified as a substitute based on the following matching parameters:

• Connector type: Header with male pin contacts
• Position count: 10 positions across 2 rows
• Mating pitch: 0.050" (1.27mm)
• Shrouding: Shrouded 4-wall construction
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surfaces
• Termination method: Solder
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The primary distinction is the mounting type: the TFM-105-12-S-D-P is surface mount, while the SBH41-NBPB-D05-ST-BK is through-hole mounted. This substitution is applicable only in designs where through-hole mounting is acceptable or preferred.

Parameter Comparison

Engineering Selection Recommendations

Both the TFM-105-12-S-D-P and SBH41-NBPB-D05-ST-BK are active production components with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts depends on mounting methodology and electrical performance requirements.

The TFM-105-12-S-D-P is suitable for surface mount applications requiring higher current capacity (2.9A per contact) and extended operating temperature range (-55°C to 125°C). The SBH41-NBPB-D05-ST-BK accommodates through-hole mounting with a lower current rating (1A per contact) and narrower operating temperature range (-40°C to 105°C). The row spacing differs between the two parts: 0.050" for the TFM-105-12-S-D-P versus 0.100" for the SBH41-NBPB-D05-ST-BK, which affects PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SBH41-NBPB-D05-ST-BK replace the TFM-105-12-S-D-P in all applications?

A: No. The SBH41-NBPB-D05-ST-BK is through-hole mounted while the TFM-105-12-S-D-P is surface mount. Substitution is only valid if the PCB design accommodates through-hole mounting. Additionally, the SBH41-NBPB-D05-ST-BK has a lower current rating (1A versus 2.9A per contact) and narrower operating temperature range.

Q: What is the difference in row spacing between these connectors?

A: The TFM-105-12-S-D-P has row spacing of 0.050" (1.27mm), while the SBH41-NBPB-D05-ST-BK has row spacing of 0.100" (2.54mm). This difference affects PCB footprint design and mating connector compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the TFM-105-12-S-D-P and SBH41-NBPB-D05-ST-BK are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What are the contact material differences?

A: The TFM-105-12-S-D-P uses phosphor bronze contacts, while the SBH41-NBPB-D05-ST-BK uses brass contacts. Both have gold plating on mating surfaces.

Q: Which part has better thermal performance?

A: The TFM-105-12-S-D-P operates across a wider temperature range (-55°C to 125°C) compared to the SBH41-NBPB-D05-ST-BK (-40°C to 105°C).

Q: What is the current-carrying capacity difference?

A: The TFM-105-12-S-D-P is rated for 2.9A per contact, while the SBH41-NBPB-D05-ST-BK is rated for 1A per contact. Applications requiring higher current density must use the TFM-105-12-S-D-P.
