Engineering Selection Recommendations

M22-2025005 (Harwin Inc., Active Status)

The M22-2025005 is the manufacturer-recommended direct upgrade from the obsolete M22-2525005. Both parts share identical core specifications: 100-position, 2.00mm pitch, male pin header with through-hole solder termination. The M22-2025005 maintains the same operating temperature range (-40°C ~ 105°C), gold contact finish, and UL94 V-0 flammability rating. The primary difference is extended contact post length (0.134" vs. 0.091"), resulting in increased overall contact length (0.331" vs. 0.287"). This part is actively manufactured and recommended for direct replacement in existing designs.

MTMM Series (Samtec Inc., Active Status)

The MTMM-150 series provides cross-manufacturer alternatives with enhanced electrical performance. All MTMM variants meet the core substitution criteria: 100-position, 2.00mm pitch, male pin header, through-hole solder termination, phosphor bronze contacts, and UL94 V-0 flammability rating. Key advantages include higher current rating (3A vs. 1A per contact) and extended operating temperature range (-55°C ~ 125°C for gold-plated variants, -55°C ~ 105°C for tin-plated variants). MTMM parts use Liquid Crystal Polymer (LCP) insulation instead of polyamide, offering improved dimensional stability.

Contact Length Variants:

MTMM parts are available in multiple contact length configurations to accommodate different PCB thicknesses and mating depths:

MTMM-150-02-G-D-115, -127, -151: 2-row configuration with varying mating contact lengths (0.115" to 0.151")
MTMM-150-03-G-D-126, -150-001, -03-S-D-132: 3-row configuration with extended overall contact length (0.302" vs. 0.255")
MTMM-150-04-G-D-120: 4-row configuration with maximum overall contact length (0.323")

Contact Finish Selection:

Gold-plated variants (MTMM-150-02-G-D, MTMM-150-03-G-D, MTMM-150-04-G-D) provide superior corrosion resistance and are recommended for general applications. Tin-plated variants (MTMM-150-02-T-D) offer cost optimization for non-corrosive environments with reduced operating temperature range (-55°C ~ 105°C).

Frequently Asked Questions (FAQ)

Q: Can M22-2025005 be used as a direct replacement for M22-2525005?

A: Yes. The M22-2025005 is the manufacturer-recommended active replacement. Both parts share identical pitch (2.00mm), position count (100), row configuration (2), contact type (male pin), mounting method (through-hole), and termination (solder). The M22-2025005 has extended contact post length, which does not affect compatibility with standard mating connectors.

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

A: Both series meet the core 100-position, 2.00mm pitch, male pin header specification. Primary differences include: (1) Current rating: MTMM provides 3A per contact vs. M22 1A per contact; (2) Operating temperature: MTMM gold-plated variants extend to -55°C ~ 125°C vs. M22 -40°C ~ 105°C; (3) Insulation material: MTMM uses Liquid Crystal Polymer (LCP) vs. M22 polyamide (PA6T); (4) Contact finish options: MTMM offers both gold and tin finishes; M22-2025005 is gold-only.

Q: How do I select the correct MTMM contact length variant?

A: Contact length selection depends on PCB thickness and connector mating depth requirements. MTMM-150-02 variants (overall length 0.255") are suitable for standard PCB applications. MTMM-150-03 variants (overall length 0.302") accommodate thicker PCBs or deeper mating requirements. MTMM-150-04 variant (overall length 0.323") provides maximum engagement depth. Consult PCB layout and mating connector specifications to determine appropriate variant.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. M22-2025005 and all MTMM-150 variants are ROHS3 compliant, meeting the same regulatory requirements as the original M22-2525005.

Q: What is the difference between gold-plated and tin-plated MTMM contacts?

A: Gold-plated MTMM variants (MTMM-150-02-G-D, MTMM-150-03-G-D, MTMM-150-04-G-D) provide superior corrosion resistance and extended operating temperature range (-55°C ~ 125°C). Tin-plated variants (MTMM-150-02-T-D) operate at -55°C ~ 105°C and are suitable for cost-sensitive applications in non-corrosive environments.

Q: Can MTMM-150-03-G-D-150-001 be used if only 99 positions are loaded?

A: MTMM-150-03-G-D-150-001 is specified with 99 positions loaded. This variant is suitable only for applications requiring 99-position configuration. For full 100-position requirements, use MTMM-150-03-G-D-126 or other variants with all 100 positions loaded.

Q: What is the inventory availability for these parts?

A: M22-2025005 has 1358 pieces in stock. MTMM variants range from 659 to 1094 pieces in stock. All parts are listed as new original inventory.
