Parameter Comparison

Engineering Selection Recommendations

Both the TMM-140-01-S-S-RE and TMM-140-01-S-S-RA are active production parts manufactured by Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on:

Product Availability: The TMM-140-01-S-S-RE maintains higher inventory levels (1077 units) compared to the TMM-140-01-S-S-RA (967 units), which may influence procurement timelines for high-volume applications.

Compliance Status: Both parts meet ROHS3 compliance requirements and carry EAR99 export classification, making them suitable for regulated applications without additional certification requirements.

Functional Equivalence: The identical contact specifications, pitch, position count, and termination method ensure direct interchangeability in circuit designs. No design modifications are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are TMM-140-01-S-S-RE and TMM-140-01-S-S-RA electrically interchangeable?
