Key Parameters

Substitute Part Grouping Explanation

The LTMM-107-02-L-D-SM qualifies as a substitute based on alignment of critical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 14
• Number of rows: 2
• Pitch - mating: 0.079" (2.00mm)
• Row spacing - mating: 0.079" (2.00mm)
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Fastening type: Push-Pull
• Contact material: Phosphor Bronze
• Insulation material: Liquid Crystal Polymer (LCP)
• Operating temperature range: -55°C ~ 125°C
• RoHS status: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Difference:

• Style: STMM-107-02-L-D-SM is configured for Board to Cable/Wire connectivity, while LTMM-107-02-L-D-SM is configured for Board to Board connectivity. This represents a functional difference in application context rather than electrical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the STMM-107-02-L-D-SM and LTMM-107-02-L-D-SM maintain active product status with ROHS3 compliance and identical MSL 1 ratings, ensuring equivalent environmental and regulatory qualification. The primary distinction lies in connector style: the STMM series is designated for board-to-cable/wire applications, while the LTMM series is designated for board-to-board applications.

Selection between these parts depends on the specific application interface requirement. When the design calls for board-to-cable/wire connectivity, the STMM-107-02-L-D-SM is the appropriate choice. When board-to-board connectivity is required, the LTMM-107-02-L-D-SM is the appropriate choice. Both parts share identical electrical characteristics, mechanical dimensions, and environmental operating parameters.

Frequently Asked Questions (FAQ)

Q: Can LTMM-107-02-L-D-SM replace STMM-107-02-L-D-SM in all applications?

A: Substitution is limited by application context. The LTMM series is designed for board-to-board mating, while the STMM series is designed for board-to-cable/wire mating. Electrical and mechanical parameters are equivalent, but the intended mating interface differs. Substitution is valid only when the application interface requirement aligns with the substitute part's design specification.

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

A: Yes. Both parts feature 0.079" (2.00mm) mating pitch and 0.079" (2.00mm) row spacing. The 14-position, 2-row configuration is identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both STMM-107-02-L-D-SM and LTMM-107-02-L-D-SM are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

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

A: Both parts operate across -55°C to 125°C, providing equivalent thermal performance.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts use phosphor bronze contacts with gold mating finish (10.0µin/0.25µm thickness) and tin post finish. Contact shape, length, and electrical characteristics are identical.

Q: What is the current rating for the LTMM-107-02-L-D-SM?

A: The current rating for LTMM-107-02-L-D-SM is not specified in the provided data. The STMM-107-02-L-D-SM is rated for 3A.
