Engineering Selection Recommendations

Harwin Series Substitution: M22-2511405 is the direct Harwin equivalent, maintaining identical electrical and mechanical specifications with the exception of 14 positions versus 13. This part is active and ROHS3 compliant, providing continuity within the same manufacturer ecosystem. Selection is appropriate for designs where the additional position does not create layout constraints.

Samtec MTMM Series Substitution: The MTMM series provides enhanced current ratings (3A per contact versus 1A) and extended operating temperature range (-55°C to 125°C versus -40°C to 105°C). All MTMM variants maintain 0.079" (2.00mm) pitch, 13-position configuration, through-hole mounting, and push-pull fastening. Variants differ in contact length specifications, accommodating different PCB thicknesses and mating depths:

MTMM-113-02-G-S-100 and MTMM-113-02-G-S-105: Shorter contact lengths (2.54mm and 2.67mm mating), suitable for standard PCB applications
MTMM-113-02-T-S-080: Tin finish alternative with reduced mating contact length (2.03mm)
MTMM-113-04-G-S-094 and MTMM-113-04-G-S-100: Extended post lengths (4.32mm and 4.17mm), for thicker PCB assemblies
MTMM-113-04-S-S-094: Mixed finish variant (gold mating, tin post)
MTMM-113-06-G-S-094: Extended post length (6.20mm) for specialized applications
MTMM-113-14-G-S-096: Maximum post length (15.14mm) for extended reach applications

All MTMM variants are active, ROHS3 compliant, and UL94 V-0 rated.

Samtec TMM Series Substitution: TMM-113-01-LM-S is a non-cuttable header variant with 13 positions, 0.079" (2.00mm) pitch, and 3.2A per contact rating. This part provides the highest current capacity and extended operating temperature range (-55°C to 125°C). The non-cuttable design differs from the original cuttable specification but maintains all other functional parameters. This part is active and ROHS3 compliant.

Compliance and Regulatory Alignment: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory continuity. All Samtec alternatives provide UL94 V-0 flammability certification. TMM-113-01-LM-S does not specify flammability rating in provided data.

Frequently Asked Questions (FAQ)

Q: Can M22-2511405 be used as a direct replacement for M22-2511305?

A: M22-2511405 is functionally compatible with M22-2511305 for applications requiring 13 or fewer positions. The primary difference is the 14-position configuration. If your design uses only 13 positions, this part is a direct substitute. Both parts share identical pitch (0.079" / 2.00mm), contact specifications, operating temperature range, and current rating (1A per contact). M22-2511405 is active, whereas M22-2511305 is obsolete.

Q: What are the key differences between Harwin M22 and Samtec MTMM series?

A: The primary differences are current rating and operating temperature range. Harwin M22-2511305 is rated 1A per contact with -40°C to 105°C operating range. Samtec MTMM series is rated 3A per contact with -55°C to 125°C operating range. Both maintain 0.079" (2.00mm) pitch, 13-position configuration, and through-hole solder termination. Harwin uses Polyamide (PA6T) insulation, while Samtec MTMM uses Liquid Crystal Polymer (LCP). Contact length specifications vary across MTMM variants to accommodate different PCB thicknesses.

Q: Which Samtec MTMM variant should I select?

A: Selection depends on PCB thickness and mating depth requirements. MTMM-113-02 variants (mating contact length 2.03mm to 2.67mm) are suitable for standard PCB applications. MTMM-113-04 variants (mating contact length 2.40mm) accommodate thicker PCBs. MTMM-113-06 and MTMM-113-14 variants provide extended post lengths for specialized applications requiring deeper insertion or extended reach. All variants maintain identical pitch, position count, and fastening type.

Q: Is the TMM-113-01-LM-S cuttable like the original M22-2511305?

A: No. TMM-113-01-LM-S is a non-cuttable header, whereas M22-2511305 is cuttable. If your application requires a cuttable header, select from the MTMM series (all cuttable) or M22-2511405 (cuttable). If non-cuttable headers are acceptable, TMM-113-01-LM-S provides the highest current rating (3.2A per contact) and extended operating temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (M22-2511405, all MTMM variants, and TMM-113-01-LM-S) are ROHS3 compliant. All maintain MSL 1 (Unlimited) moisture sensitivity level, matching the original M22-2511305 specification.

Q: What is the difference between gold and tin contact finishes?

A: Gold finish (MTMM-113-02-G-S-100, MTMM-113-02-G-S-105, and others) provides superior corrosion resistance and lower contact resistance. Tin finish (MTMM-113-02-T-S-080) is cost-effective but offers reduced corrosion resistance. For applications requiring maximum reliability and longevity, gold-finished contacts are preferred. The original M22-2511305 uses gold finish.

Q: Can I use a higher current-rated part (3A) in place of the 1A-rated original?

A: Yes. Using a higher current-rated part does not create compatibility issues. The 3A-rated Samtec alternatives (MTMM and TMM series) are fully compatible with designs originally specified for 1A per contact. The higher current rating provides additional design margin and reliability headroom.

Q: What is the operating temperature difference between M22-2511305 and Samtec alternatives?

A: M22-2511305 operates from -40°C to 105°C. Samtec MTMM and TMM series operate from -55°C to 125°C, providing 15°C lower minimum temperature and 20°C higher maximum temperature. This extended range accommodates more demanding thermal environments and provides additional design flexibility.
