TMM-116-01-G-D-SM-A Equivalent & Substitute Parts

Part Overview

The TMM-116-01-G-D-SM-A is a 2MM terminal strip connector header manufactured by Samtec Inc. This surface mount rectangular connector features 32 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing. The connector is actively produced and stocked, with 863 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in board-to-board or cable applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the TMM-116-01-G-D-SM-A is based on strict alignment of the following critical parameters:

• Connector type: Header with male pin contacts
• Position count: 32 positions
• Row configuration: 2 rows
• Mating pitch: 0.079" (2.00mm)
• Row spacing: 0.079" (2.00mm)
• Mounting method: Surface mount
• Termination method: Solder
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surface
• Insulation height: 0.059" (1.50mm)
• Contact shape: Square
• Flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The Molex 0877593250 (Milli-Grid 87759 series) meets these core substitution criteria. Variations in contact length, contact finish thickness, and insulation material do not preclude functional equivalence when these parameters remain within acceptable tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the TMM-116-01-G-D-SM-A and 0877593250 are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Samtec TMM-116-01-G-D-SM-A: Primary choice when LCP insulation material is specified or when the 0.126" (3.20mm) mating contact length is required by the application design.

Molex 0877593250: Suitable alternative when thermoplastic insulation material is acceptable and the 0.150" (3.81mm) mating contact length accommodates the mating connector design. The breakaway feature provides additional flexibility for certain assembly configurations.

Both parts maintain equivalent electrical performance with gold-plated phosphor bronze contacts, identical pitch spacing, and identical row configuration. Inventory availability should be evaluated based on procurement lead times and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0877593250 be used as a direct replacement for the Samtec TMM-116-01-G-D-SM-A?

A: Yes, when the application tolerates the differences in contact length (0.150" vs. 0.126") and insulation material (thermoplastic vs. LCP). Both connectors share identical pitch spacing, row configuration, position count, and contact type. Mating connector compatibility must be verified based on the specific receptacle design.

Q: What is the significance of the contact length difference between these parts?

A: The Molex part has a 0.024" (0.61mm) longer mating contact length. This difference affects the depth of insertion into the mating receptacle. The application's mating connector design must accommodate this variation to ensure proper electrical contact and mechanical engagement.

Q: Are there differences in insulation material that affect performance?

A: The Samtec part uses Liquid Crystal Polymer (LCP) insulation, while the Molex part uses thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range of -55°C to 125°C. Material selection depends on specific environmental and mechanical requirements of the application.

Q: What does the breakaway feature on the Molex connector provide?

A: The breakaway feature allows individual connector sections to be separated from the main header assembly. This provides flexibility in applications requiring partial connector configurations or modular assembly approaches.

Q: Are both parts RoHS compliant?

A: Yes, both the Samtec TMM-116-01-G-D-SM-A and Molex 0877593250 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, making them suitable for standard PCB assembly and storage conditions.
