STMM-107-02-T-D-SM Equivalent & Substitute Parts

Part Overview

The STMM-107-02-T-D-SM is a rectangular connector header manufactured by Samtec Inc., designed for surface mount applications. This shrouded 14-position header operates across -55°C to 105°C and features a 2.00mm pitch with push-pull fastening. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are required for board-to-cable or board-to-board applications, or when inventory constraints necessitate alternative sourcing from the same manufacturer's product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STMM-107-02-T-D-SM is determined by strict equivalence across the following critical parameters:

• Pitch and row spacing (0.079" / 2.00mm)
• Number of positions and rows (14 positions, 2 rows)
• Contact type and material (Male Pin, Phosphor Bronze)
• Mounting method (Surface Mount, Solder termination)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening mechanism (Push-Pull)
• Operating temperature range (-55°C ~ 105°C)
• Compliance certifications (ROHS3, MSL 1)

The LTMM-107-02-T-D-SM qualifies as a substitute based on these parameters. Both parts share identical electrical and mechanical specifications with the exception of connector style: STMM-107-02-T-D-SM is configured for board-to-cable/wire applications, while LTMM-107-02-T-D-SM is configured for board-to-board applications. This distinction affects mating interface design but does not alter the core electrical performance or physical dimensions of the header itself.

Parameter Comparison

Engineering Selection Recommendations

Both STMM-107-02-T-D-SM and LTMM-107-02-T-D-SM maintain active product status with ROHS3 compliance and MSL 1 rating. Selection between these parts depends on application interface requirements: STMM-107-02-T-D-SM is specified for board-to-cable/wire interconnection, while LTMM-107-02-T-D-SM is specified for board-to-board interconnection. The electrical and mechanical performance characteristics are equivalent across both parts. Current inventory levels are 1126 units for STMM-107-02-T-D-SM and 1010 units for LTMM-107-02-T-D-SM.

Frequently Asked Questions (FAQ)

Q: Can LTMM-107-02-T-D-SM replace STMM-107-02-T-D-SM in a board-to-cable application?

A: LTMM-107-02-T-D-SM is specified for board-to-board applications. While the header contact geometry and electrical specifications are identical, the connector style designation indicates different mating interface design. Application compatibility depends on the mating connector type used in the system.

Q: Are the pitch and row spacing identical between these parts?

A: Yes. Both STMM-107-02-T-D-SM and LTMM-107-02-T-D-SM feature 0.079" (2.00mm) pitch and 0.079" (2.00mm) row spacing.

Q: Do both parts support the same operating temperature range?

A: Yes. Both parts operate across -55°C to 105°C.

Q: What is the current rating for these connectors?

A: STMM-107-02-T-D-SM is rated for 3A. Current rating data for LTMM-107-02-T-D-SM is not provided in the specification.

Q: Are both parts RoHS compliant?

A: Yes. Both STMM-107-02-T-D-SM and LTMM-107-02-T-D-SM are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the contact material and finish for these headers?

A: Both parts feature Phosphor Bronze contacts with Tin finish on both mating and post surfaces.
