Parameter Comparison

Engineering Selection Recommendations

Both TMMH-109-01-G-DV and TMMH-109-01-G-DV-ES-A are active production parts manufactured by Samtec Inc. and are fully compliant with ROHS3 and UL94 V-0 flammability requirements. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, contact geometry, termination method, and operating temperature range.

The TMMH-109-01-G-DV-ES-A includes board guide and end shroud features not present in the base TMMH-109-01-G-DV. Selection between these parts should be based on PCB layout requirements and mechanical assembly considerations. The TMMH-109-01-G-DV-ES-A currently has higher inventory availability (1303 units versus 814 units).

Frequently Asked Questions (FAQ)

Q: Are TMMH-109-01-G-DV and TMMH-109-01-G-DV-ES-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including contact material (phosphor bronze), contact finish (gold), pitch (0.079" / 2.00mm), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between these two part numbers?

A: The TMMH-109-01-G-DV-ES-A includes board guide and end shroud features. The base TMMH-109-01-G-DV does not include these mechanical features. Both parts are mechanically compatible for board-to-board and cable applications.

Q: Can I use TMMH-109-01-G-DV-ES-A as a direct replacement for TMMH-109-01-G-DV?

A: Direct substitution is possible from an electrical standpoint. PCB layout and mechanical assembly design must accommodate the additional board guide and end shroud features present on the TMMH-109-01-G-DV-ES-A.

Q: Are both parts RoHS compliant?

A: Yes. Both TMMH-109-01-G-DV and TMMH-109-01-G-DV-ES-A are ROHS3 compliant.

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

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

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -55°C to 125°C and carry UL94 V-0 flammability certification.
