Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTMM-120-05-SM-D-200 are determined by strict equivalence across the following critical parameters:

• Connector series (MTMM)
• Number of positions (40) and row configuration (2 rows)
• Pitch spacing (0.079" / 2.00mm mating and row spacing)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact geometry (length, shape, material)
• Contact finish specifications (Gold mating, Tin post)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3A)
• Compliance certifications (UL94 V-0, ROHS3)

The MTMM-120-05-S-D-200 qualifies as a direct substitute because it maintains identical specifications across all these parameters. Variations in part numbering reflect packaging or minor configuration differences that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MTMM-120-05-SM-D-200 and MTMM-120-05-S-D-200 are active products manufactured by Samtec Inc. and carry identical electrical, mechanical, and compliance specifications. Selection between these parts may be based on packaging availability, inventory status, or procurement lead times, as both parts maintain full ROHS3 compliance and UL94 V-0 flammability certification. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part. Current inventory levels show 681 units of the main part and 726 units of the substitute part available as new original stock.

Frequently Asked Questions (FAQ)

Q: Are MTMM-120-05-SM-D-200 and MTMM-120-05-S-D-200 electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3A current rating, contact material (Phosphor Bronze), contact finish (Gold mating surface, Tin post), and operating temperature range (-55°C ~ 125°C).

Q: Do these parts have the same physical footprint?

A: Yes. Both connectors maintain identical mechanical dimensions: 40 positions in 2 rows, 0.079" (2.00mm) pitch spacing, 0.200" (5.08mm) mating contact length, and 0.059" (1.50mm) insulation height. PCB layout and mounting hole patterns are identical.

Q: What does the part number variation indicate?

A: The difference between MTMM-120-05-SM-D-200 and MTMM-120-05-S-D-200 reflects packaging or configuration variants within the MTMM-120 base product family. Both parts are functionally equivalent for board-to-board and cable interconnect applications.
