MTMM-107-07-G-D-126 Equivalent & Substitute Parts

Part Overview

The MTMM-107-07-G-D-126 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This vertical header connector features 14 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing. The connector is actively produced and maintains full inventory availability. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTMM-107-07-G-D-126 is determined by the following critical parameters:

• Connector Position and Row Configuration: 14 positions in 2 rows (non-negotiable for mechanical fit)
• Pitch Spacing: 0.079" (2.00mm) mating pitch and row spacing (required for mating compatibility)
• Mounting Method: Through-hole termination (required for PCB assembly compatibility)
• Contact Type: Male pin header (required for mating interface)
• Operating Temperature Range: -55°C ~ 125°C (minimum acceptable performance envelope)
• Current Rating: Minimum 3A per contact (functional requirement)
• Compliance: ROHS3 compliance (regulatory requirement)

The substitute part TMM-107-01-S-D meets all critical substitution criteria. Both parts share identical position count, row configuration, pitch spacing, mounting type, contact type, operating temperature range, and regulatory compliance status. Variations in contact post length, contact finish thickness, and current rating per contact do not preclude substitution when the substitute part meets or exceeds the functional requirements of the primary application.

Parameter Comparison

Engineering Selection Recommendations

Both the MTMM-107-07-G-D-126 and TMM-107-01-S-D are active products manufactured by Samtec Inc. with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on the following factors:

MTMM-107-07-G-D-126 is appropriate when longer contact post length (0.271" / 6.88mm) is required for applications with thicker PCB assemblies or when extended solder joint engagement is necessary.

TMM-107-01-S-D is appropriate when shorter contact post length (0.138" / 4.60mm) is suitable for standard PCB thickness applications. This part offers higher current rating per contact (3.2A versus 3A) and represents an alternative sourcing option with equivalent mechanical and electrical compatibility.

Both parts maintain identical mating contact length, pitch spacing, position configuration, and operating temperature range, ensuring functional interchangeability within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can TMM-107-01-S-D be used as a direct replacement for MTMM-107-07-G-D-126?

A: Yes, within the constraints of PCB design. Both connectors share identical mating pitch (0.079" / 2.00mm), position count (14), row configuration (2 rows), and mounting type (through-hole). The primary design consideration is contact post length: MTMM-107-07-G-D-126 has 0.271" posts while TMM-107-01-S-D has 0.138" posts. Verify that your PCB thickness and solder joint requirements are compatible with the shorter post length of the substitute part.

Q: What are the key parameters that determine substitution eligibility?

A: Critical substitution parameters are: 14-position count, 2-row configuration, 0.079" (2.00mm) pitch spacing, through-hole mounting, male pin contact type, -55°C to 125°C operating temperature range, minimum 3A current rating, and ROHS3 compliance. Variations in contact post length, contact finish thickness, and current rating above the minimum threshold do not preclude substitution.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are classified under ECCN EAR99. Both are active products with full inventory availability. No compliance or certification barriers exist to substitution.

Q: How does the difference in contact post length affect PCB assembly?

A: Contact post length determines the depth of solder joint engagement with the PCB. MTMM-107-07-G-D-126 (0.271" posts) provides greater solder engagement suitable for thicker PCBs or applications requiring maximum mechanical strength. TMM-107-01-S-D (0.138" posts) is optimized for standard PCB thickness. Verify your PCB thickness specification before selecting the appropriate part.

Q: What is the difference in current rating between these parts?

A: MTMM-107-07-G-D-126 is rated at 3A per contact, while TMM-107-01-S-D is rated at 3.2A per contact. If your application requires the full 3A rating, both parts are suitable. TMM-107-01-S-D provides additional current capacity margin.
