Substitute Part Grouping Explanation

Substitute parts within the MTMM-112 series are qualified based on the following invariant parameters that must remain constant across all substitutes:

Pitch - Mating: 0.079" (2.00mm)
Number of Positions: 24
Number of Rows: 2
Row Spacing - Mating: 0.079" (2.00mm)
Connector Type: Header, Cuttable
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder

Engineering Selection Recommendations

All substitute parts listed maintain active product status with Samtec Inc. and carry ROHS3 compliance certification. Selection between substitute parts is determined by the specific contact length and overall connector height requirements of the target application. The MTMM-112-14-G-D-000 reference part does not specify contact length dimensions; substitute selection should be based on matching the required mating depth and post height to the PCB stack-up and connector cavity specifications of the receiving connector. All listed alternatives maintain identical electrical ratings, temperature operating range, and material specifications, ensuring functional interchangeability within the specified dimensional constraints.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between MTMM-112-14-G-D-000 and its substitute parts?

A: Compatibility is determined by matching pitch spacing (0.079" / 2.00mm), position count (24), row configuration (2 rows), contact material (Phosphor Bronze), and electrical ratings (3A, -55°C to 125°C). The primary variable is contact length, which must align with the receiving connector cavity depth and PCB stack-up requirements.

Q: Can MTMM-112 series headers be used interchangeably in the same PCB footprint?

A: No. While all parts share identical pitch and position specifications, the contact length and overall connector height vary significantly across the series. The PCB footprint and receiving connector cavity must accommodate the specific contact length of the selected part number.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts in the MTMM-112 series listed carry ROHS3 compliance certification and maintain identical material flammability ratings (UL94 V-0).

Q: What is the difference between Contact Length - Mating and Contact Length - Post?

A: Contact Length - Mating specifies the engagement depth into the receiving connector. Contact Length - Post specifies the solder tail length extending below the PCB. Both dimensions must be verified against the target application requirements.

Q: Are moisture sensitivity considerations the same across all substitute parts?

A: Yes. All parts maintain Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
