Frequently Asked Questions (FAQ)

Q: Are TMM-122-01-L-D-RA and TMM-122-01-LM-D-RA direct substitutes for TMM-122-01-L-D-RE?

A: Yes. Both parts maintain identical electrical specifications, mechanical dimensions, pitch spacing, contact configuration, and current ratings. All three parts are functionally equivalent for applications requiring a 44-position, 2-row, 2.00mm pitch rectangular connector header with through-hole right-angle mounting.

Q: What determines compatibility between these connector parts?

A: Compatibility is determined by matching connector type, position count, row configuration, pitch spacing, contact type, mounting style, termination method, and current rating. All three parts share these critical parameters.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The parts share identical mechanical footprints, pitch spacing (0.079" / 2.00mm), and mounting type (through-hole, right-angle). PCB layouts designed for one part accommodate the others without modification.

Q: Are there differences in contact finish or material composition?

A: No. All three parts feature gold-plated mating contacts with phosphor bronze material and tin-plated posts. Contact finish thickness and material specifications are identical.

Q: What is the operating temperature range for these connectors?

A: All three parts operate across -55°C to 125°C, supporting applications requiring extended temperature performance.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. All three parts are ROHS3 compliant, meeting environmental and hazardous substance restrictions.
