Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMM-108-01-G-S-RE are identified within the TMM series based on the following critical parameters that determine functional equivalence:

• Pitch - Mating: 0.079" (2.00mm) — determines mechanical compatibility with mating connectors
• Number of Positions: 8 — defines circuit density and contact count
• Connector Type: Header — specifies the connector class
• Contact Type: Male Pin — determines gender compatibility
• Mounting Type: Through Hole, Right Angle — defines PCB assembly method
• Termination: Solder — specifies connection method
• Current Rating: 3.2A per Contact — establishes electrical capacity
• Operating Temperature: -55°C ~ 125°C — defines thermal operating envelope
• Contact Material and Finish: Phosphor Bronze with Gold plating — ensures electrical performance and reliability
• Insulation Material: Liquid Crystal Polymer (LCP) — provides mechanical and thermal stability
• RoHS Status: ROHS3 Compliant — ensures regulatory compliance

The TMM-108-01-G-S-RA maintains all critical parameters identical to the main part, confirming direct substitution capability within the TMM series.

Frequently Asked Questions (FAQ)

Q: Can TMM-108-01-G-S-RA be used as a direct replacement for TMM-108-01-G-S-RE?

A: Yes. Both parts share identical electrical and mechanical parameters, including pitch, position count, contact rating, operating temperature range, and material specifications. Direct substitution is supported within the TMM series.

Q: What determines compatibility between these connector headers?

A: Compatibility is established through matching pitch (0.079" / 2.00mm), position count (8), contact type (male pin), mounting method (through-hole right angle), current rating (3.2A per contact), and operating temperature range (-55°C to 125°C).

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

A: No. Both parts maintain identical ROHS3 compliance status and MSL 1 rating. Both are active production parts with no restrictions on manufacturing or storage.

Q: What is the significance of the part number suffix in TMM-108-01-G-S-RE versus TMM-108-01-G-S-RA?

A: The suffix designates specific connector configuration variants within the TMM series. Both variants maintain the same core electrical and mechanical specifications for the 8-position 2.00mm pitch header configuration.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes, provided the PCB layout accommodates the through-hole right-angle mounting configuration. The identical pitch, position count, and contact dimensions ensure mechanical and electrical interchangeability.
