TSM-121-01-L-DV Equivalent & Substitute Parts

Part Overview

The TSM-121-01-L-DV is a surface mount rectangular connector header manufactured by Samtec Inc., configured as a 42-position, 2-row cuttable header with 0.100" (2.54mm) pitch. This connector is designed for board-to-board or cable applications with solder termination and push-pull fastening. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. Substitute parts are identified when electrical and mechanical parameters remain identical across the connector specification, allowing direct functional replacement in applications where the main part number becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitute parts for the TSM-121-01-L-DV are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Matching Parameters:

• Connector type, contact type, and gender (Header, Cuttable; Male Pin)
• Position count and row configuration (42 positions, 2 rows)
• Pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Mounting technology (Surface Mount)
• Termination method (Solder)
• Contact geometry and materials (Square shape, Phosphor Bronze, Gold mating finish at 10.0µin)
• Insulation material and temperature rating (LCP, -55°C ~ 125°C)
• Compliance certifications (ROHS3, UL94 V-0, MSL 1)

The identified substitutes—TSM-121-01-L-DV-A and TSM-121-01-L-DV-A-P—maintain identical electrical and mechanical specifications. Differences in features (Board Guide, Pick and Place) represent manufacturing enhancements that do not alter core connector functionality or compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—TSM-121-01-L-DV, TSM-121-01-L-DV-A, and TSM-121-01-L-DV-A-P—are active products from Samtec Inc. with identical electrical and mechanical specifications. Each part maintains ROHS3 compliance, UL94 V-0 flammability certification, and MSL 1 moisture sensitivity rating.

Selection between these parts should be based on application requirements and manufacturing process considerations. TSM-121-01-L-DV-A introduces a Board Guide feature, which provides mechanical alignment assistance during assembly. TSM-121-01-L-DV-A-P adds Pick and Place compatibility in addition to the Board Guide feature, supporting automated assembly processes.

For applications requiring manual assembly without specific alignment aids, TSM-121-01-L-DV remains functionally equivalent. For applications utilizing automated pick-and-place assembly equipment, TSM-121-01-L-DV-A-P is the appropriate selection. TSM-121-01-L-DV-A serves as an intermediate option for applications requiring board guidance without full pick-and-place optimization.

Frequently Asked Questions (FAQ)

Q: Are TSM-121-01-L-DV, TSM-121-01-L-DV-A, and TSM-121-01-L-DV-A-P electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including contact material (Phosphor Bronze), contact finish (Gold at 10.0µin mating surface, Tin post), operating temperature range (-55°C ~ 125°C), and insulation material (LCP). They are electrically equivalent for all circuit applications.

Q: What is the difference between these part numbers?

A: The primary differences are manufacturing features. TSM-121-01-L-DV-A adds a Board Guide feature for mechanical alignment. TSM-121-01-L-DV-A-P includes both Board Guide and Pick and Place features for automated assembly compatibility. Core connector functionality remains identical across all three parts.

Q: Can I substitute TSM-121-01-L-DV-A-P for TSM-121-01-L-DV in a manual assembly application?

A: Yes. TSM-121-01-L-DV-A-P maintains all electrical and mechanical specifications of TSM-121-01-L-DV. The additional Pick and Place feature does not affect manual assembly compatibility. The part will function identically in the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. TSM-121-01-L-DV, TSM-121-01-L-DV-A, and TSM-121-01-L-DV-A-P are all ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the pitch specification for these connectors?

A: All three parts feature 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing in a 2-row, 42-position configuration.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All three parts are rated for operating temperatures from -55°C to 125°C, supporting both industrial and consumer-grade thermal environments.
