STMM-107-02-G-D-RA Equivalent & Substitute Parts

Part Overview

The STMM-107-02-G-D-RA is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-cable/wire applications. This 14-position, 2-row connector operates across -55°C to 125°C and features shrouded 4-wall construction with push-pull fastening. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STMM-107-02-G-D-RA is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 14
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C

The LTMM-107-02-G-D-RA meets all these criteria and qualifies as a direct substitute. The primary distinction is the application style: STMM-107-02-G-D-RA is configured for board-to-cable/wire connections, while LTMM-107-02-G-D-RA is configured for board-to-board connections. Both share identical electrical and mechanical specifications for mating interface, contact geometry, and environmental performance.

Parameter Comparison

Engineering Selection Recommendations

Both the STMM-107-02-G-D-RA and LTMM-107-02-G-D-RA are active products from Samtec Inc. with identical ROHS3 compliance and EAR99 classification. Selection between these parts depends on application topology:

Use STMM-107-02-G-D-RA for board-to-cable/wire interconnect applications where the connector header mounts to a PCB and interfaces with external cabling.

Use LTMM-107-02-G-D-RA for board-to-board interconnect applications where the connector header mounts to a PCB and interfaces with a mating connector on another PCB.

Both parts share identical mating interface specifications, contact geometry, electrical ratings, and environmental performance. The choice between them is determined by the physical connection topology required by the application, not by electrical or thermal limitations.

Frequently Asked Questions (FAQ)

Q: Can LTMM-107-02-G-D-RA replace STMM-107-02-G-D-RA in my application?

A: Substitution is possible only if your application topology permits board-to-board connection instead of board-to-cable/wire connection. The mating interface specifications are identical, but the intended connection style differs. Verify that your system design can accommodate the board-to-board configuration before substitution.

Q: What are the key parameters that must match for substitution?

A: Critical matching parameters include pitch (0.079" / 2.00mm), position count (14), row count (2), row spacing (0.079" / 2.00mm), shrouding type (4-wall), mounting style (through-hole right-angle), contact material (phosphor bronze), contact finish (gold), insulation material (LCP), and operating temperature range (-55°C to 125°C).

Q: Are there electrical performance differences between these parts?

A: No. Both parts share identical contact geometry, material composition, finish specifications, and operating temperature range. The STMM-107-02-G-D-RA specifies a 3A current rating; the LTMM-107-02-G-D-RA does not specify a current rating in the provided data, but both use identical contact materials and geometry.

Q: What is the difference in insulation height between these parts?

A: The STMM-107-02-G-D-RA has an insulation height of 0.236" (6.00mm), while the LTMM-107-02-G-D-RA has 0.237" (6.03mm). This 0.001" (0.03mm) difference is within typical manufacturing tolerance and does not affect functional compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both STMM-107-02-G-D-RA and LTMM-107-02-G-D-RA are ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).
