TSM-103-03-L-DV Equivalent & Substitute Parts

Part Overview

The TSM-103-03-L-DV is a surface mount rectangular connector header manufactured by Samtec Inc., designed for board-to-board or cable applications. This 6-position, 2-row connector operates across -55°C to 125°C and features gold-plated mating contacts with phosphor bronze material. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. Alternative models may be required due to inventory constraints, specific application requirements, or design revisions that necessitate functionally equivalent components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TSM-103-03-L-DV is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header, Cuttable with Male Pin contacts
• Position & Row Configuration: 6 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Environmental & Compliance Requirements: Operating temperature range -55°C to 125°C, ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1

The identified substitute part TSM-103-03-L-DV-A maintains full equivalence across all critical parameters. The only documented difference is the addition of a Board Guide feature in the substitute variant, which represents an enhancement rather than a functional deviation. Both parts share the same base product number (TSM-103), manufacturer, series designation, and all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both TSM-103-03-L-DV and TSM-103-03-L-DV-A are active production components with identical compliance certifications and electrical specifications. Selection between these parts should be based on the following criteria:

TSM-103-03-L-DV is suitable for applications where standard header functionality without additional mechanical guidance is sufficient. Current inventory availability is 789 pieces.

TSM-103-03-L-DV-A is suitable for applications requiring enhanced mechanical alignment through the integrated Board Guide feature. This variant provides improved positional stability during assembly and mating operations. Current inventory availability is 955 pieces.

Both parts maintain ROHS3 compliance, UL94 V-0 flammability certification, and MSL 1 rating. The selection between variants does not impact regulatory compliance or environmental operating parameters. The Board Guide feature in the TSM-103-03-L-DV-A represents a design enhancement that improves assembly reliability without altering the fundamental electrical or thermal characteristics of the connector.

Frequently Asked Questions (FAQ)

Q: Can TSM-103-03-L-DV-A be used as a direct replacement for TSM-103-03-L-DV?

A: Yes. Both parts share identical electrical specifications, contact configurations, pitch dimensions, mounting type, and operating temperature range. The Board Guide feature in the TSM-103-03-L-DV-A is an enhancement that does not compromise compatibility with applications designed for the standard TSM-103-03-L-DV.

Q: What is the functional difference between these two parts?

A: The TSM-103-03-L-DV-A includes a Board Guide feature that provides mechanical alignment assistance during connector mating. All other specifications—including contact type, pitch, row spacing, termination method, and environmental ratings—are identical.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both TSM-103-03-L-DV and TSM-103-03-L-DV-A are ROHS3 compliant, carry UL94 V-0 flammability certification, and have MSL 1 rating. No regulatory differences exist between the variants.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing. This is a standard pitch for rectangular connectors in this category.

Q: Can these connectors be cut to reduce the number of positions?

A: Yes. Both TSM-103-03-L-DV and TSM-103-03-L-DV-A are designated as "Cuttable" header connectors, allowing the connector to be sectioned to accommodate applications requiring fewer than 6 positions.

Q: What is the operating temperature range for these parts?

A: Both connectors operate across -55°C to 125°C, suitable for industrial and commercial applications with extended temperature requirements.

Q: Are there any differences in contact finish or material composition?

A: No. Both parts feature gold-plated mating contacts with 10.0µin (0.25µm) thickness, tin-plated posts, and phosphor bronze contact material. Contact specifications are identical.
