Parameter Comparison

Engineering Selection Recommendations

All three parts—TMM-122-01-LM-D-SM-P, TMM-122-01-L-D-SM-M, and TMM-122-01-L-D-SM-P—are active products from Samtec Inc. with identical electrical and mechanical specifications. Each part is ROHS3 compliant and carries UL94 V-0 material flammability certification, meeting regulatory requirements for industrial and commercial applications.

Selection between these parts should be based on inventory availability and lead time requirements. TMM-122-01-L-D-SM-P offers the highest current inventory at 852 units, followed by TMM-122-01-LM-D-SM-P at 814 units, and TMM-122-01-L-D-SM-M at 753 units. All parts are suitable for applications requiring 44-position, 2-row surface mount headers with 2.00mm pitch spacing and 3.2A per contact current capacity across the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are TMM-122-01-L-D-SM-M and TMM-122-01-L-D-SM-P direct substitutes for TMM-122-01-LM-D-SM-P?

A: Yes. All three parts share identical electrical and mechanical specifications including connector type, contact configuration, pitch spacing, mounting type, termination method, contact materials, and operating parameters. They are functionally equivalent for applications requiring this connector specification.

Q: What are the key parameters that determine substitutability for this connector?

A: Substitutability is determined by matching: number of positions (44), number of rows (2), pitch spacing (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), contact type (Male Pin), mounting type (Surface Mount), termination (Solder), fastening type (Push-Pull), contact length (0.126" / 3.20mm), insulation height (0.059" / 1.50mm), contact material (Phosphor Bronze), insulation material (Liquid Crystal Polymer), contact finish (Gold mating / Tin post), and current rating (3.2A per contact).

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and carry UL94 V-0 material flammability certification. They are all active products suitable for applications requiring these regulatory certifications.

Q: What is the difference between these part numbers?

A: The part numbers differ in their coding scheme within the TMM series, but all three parts deliver identical form, fit, and function. Differences in part number designation do not reflect differences in electrical or mechanical performance.

Q: Which part should I select based on availability?

A: TMM-122-01-L-D-SM-P has the highest inventory at 852 units. TMM-122-01-LM-D-SM-P has 814 units, and TMM-122-01-L-D-SM-M has 753 units. Selection should be based on lead time and procurement requirements.
