TSM-105-03-L-SH Equivalent & Substitute Parts

Part Overview

The TSM-105-03-L-SH is a surface mount, right-angle rectangular connector header manufactured by Samtec Inc. This 5-position connector operates across the industrial temperature range of -55°C to 125°C and features gold-plated mating contacts with phosphor bronze material. The part is Active status and ROHS3 compliant, making it suitable for applications requiring board-to-board or cable interconnection in controlled environments. Substitute parts are identified to provide alternative sourcing options when the primary part number reaches inventory constraints or when design flexibility permits equivalent configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-105-03-L-SH is determined by strict equivalence across the following critical parameters:

Connector configuration: 5-position, single-row header with 0.100" (2.54mm) pitch mating spacing Mounting and orientation: Surface mount, right-angle configuration Contact system: Male pin, phosphor bronze material with gold-plated mating surface Termination method: Solder attachment Fastening mechanism: Push-pull engagement Thermal and compliance requirements: Operating range -55°C to 125°C, UL94 V-0 flammability rating, ROHS3 compliance

The substitute part TSM-105-03-L-SH-A maintains all critical electrical and mechanical parameters identical to the main part. The only documented difference is the inclusion of a board guide feature in the substitute variant, which represents an enhancement rather than a deviation from the core connector specification.

Parameter Comparison

Engineering Selection Recommendations

Both TSM-105-03-L-SH and TSM-105-03-L-SH-A are Active status products from Samtec Inc. and maintain full ROHS3 compliance with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

TSM-105-03-L-SH is the baseline configuration without additional features. This part is suitable for applications where standard header functionality meets design requirements.

TSM-105-03-L-SH-A includes a board guide feature and is recommended when mechanical alignment assistance during mating operations is beneficial. This variant provides enhanced positioning control without altering the core connector electrical or thermal characteristics.

Both parts support the full operating temperature range of -55°C to 125°C and maintain UL94 V-0 flammability compliance. Inventory availability should be considered as a secondary factor: TSM-105-03-L-SH-A currently maintains higher stock levels (2161 pcs) compared to TSM-105-03-L-SH (664 pcs).

Frequently Asked Questions (FAQ)

Q: Are TSM-105-03-L-SH and TSM-105-03-L-SH-A electrically interchangeable?

A: Yes. Both parts maintain identical contact material, pitch spacing, mating contact finish, and operating temperature range. They are electrically equivalent and can be used interchangeably in circuit designs.

Q: What is the functional difference between these two part numbers?

A: The TSM-105-03-L-SH-A includes a board guide feature that provides mechanical alignment assistance during connector mating. The TSM-105-03-L-SH does not include this feature. This difference is mechanical only and does not affect electrical performance.

Q: Can I substitute TSM-105-03-L-SH-A for TSM-105-03-L-SH in an existing design?

A: Yes. The board guide feature in TSM-105-03-L-SH-A is an enhancement that does not conflict with designs specified for TSM-105-03-L-SH. Physical dimensions and mating characteristics remain equivalent.

Q: What does the "-A" suffix indicate in TSM-105-03-L-SH-A?

A: The "-A" suffix designates the board guide variant within the TSM-105-03-L-SH product family. This is a manufacturer-defined revision indicator for the enhanced configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both TSM-105-03-L-SH and TSM-105-03-L-SH-A are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for unrestricted storage and handling.

Q: What is the pitch spacing for these connectors?

A: Both parts feature 0.100" (2.54mm) pitch mating spacing, which is the standard spacing for this connector family and determines compatibility with mating receptacles.
