Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTMM-107-02-L-D-RA is determined by strict alignment of the following critical 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: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant

The STMM-107-02-L-D-RA qualifies as a substitute part based on matching all critical mechanical and electrical parameters. Differences in series designation (STMM vs. LTMM), application style (Board to Cable/Wire vs. Board to Board), and operating temperature range represent design variations within compatible connector families and do not preclude substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both the LTMM-107-02-L-D-RA and STMM-107-02-L-D-RA maintain active product status and ROHS3 compliance. Selection between these parts is based on application-specific requirements:

The LTMM-107-02-L-D-RA operates within a -55°C to 105°C temperature range and is designated for board-to-board applications.

The STMM-107-02-L-D-RA operates within a -55°C to 125°C temperature range and is designated for board-to-cable/wire applications. This part includes a current rating specification of 3A.

Where operating temperature requirements exceed 105°C, the STMM-107-02-L-D-RA is the appropriate selection. Where board-to-board connectivity is the primary application requirement, the LTMM-107-02-L-D-RA remains the specified part. Both parts satisfy identical mechanical and electrical interface requirements for 14-position, 2.00mm pitch, right-angle header connectors with gold-plated mating contacts.

Frequently Asked Questions (FAQ)

Q: Can STMM-107-02-L-D-RA be used as a direct replacement for LTMM-107-02-L-D-RA?

A: The STMM-107-02-L-D-RA matches all critical mechanical parameters including position count, pitch, shrouding, and contact materials. Substitution is permissible where application requirements do not mandate board-to-board connectivity as the exclusive interface style. Verify that the board-to-cable/wire application style of the STMM series aligns with your circuit design.

Q: What are the key differences between these two parts?

A: The primary differences are series designation (LTMM vs. STMM), application style (board-to-board vs. board-to-cable/wire), operating temperature range (105°C vs. 125°C maximum), and current rating specification (not provided for LTMM vs. 3A for STMM). All other mechanical and electrical parameters remain identical.

Q: Are both parts RoHS compliant?

A: Yes, both LTMM-107-02-L-D-RA and STMM-107-02-L-D-RA are ROHS3 compliant.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Do these connectors include keying features?

A: Yes, both parts include a keying slot feature to ensure correct mating orientation.
