Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTMM-104-03-S-S-150 is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 4
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts M22-2010405 and M22-2510405 from Harwin Inc. meet these core electrical and mechanical requirements. Both parts maintain identical pitch, position count, row configuration, contact type, mounting method, termination style, fastening mechanism, contact geometry, mating finish, base material, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with ROHS3 compliance and UL94 V-0 flammability certification. The primary differentiators between the MTMM-104-03-S-S-150 and its Harwin substitutes are operating temperature range and current rating per contact.

The MTMM-104-03-S-S-150 supports a maximum operating temperature of 125°C with a 3A current rating. The M22-2010405 operates to 105°C with 1A per contact rating. The M22-2510405 operates to 105°C with 1A per contact rating and a minimum operating temperature of -40°C.

Selection between these parts depends on application thermal and current requirements. Applications requiring operation above 105°C or current loads exceeding 1A per contact require the MTMM-104-03-S-S-150. Applications within the -40°C to 105°C range with current requirements of 1A or less per contact are compatible with either Harwin substitute.

Frequently Asked Questions (FAQ)

Q: Can M22-2010405 or M22-2510405 be used as direct replacements for MTMM-104-03-S-S-150?

A: Both Harwin parts share identical mating pitch (2.00mm), position count (4), row configuration (1), contact type (male pin), mounting method (through hole), termination (solder), and fastening mechanism (push-pull). Substitution is mechanically and electrically compatible within the operating temperature and current constraints of the Harwin parts.

Q: What are the key differences between M22-2010405 and M22-2510405?

A: Both parts are electrically and mechanically equivalent. The primary difference is the minimum operating temperature: M22-2010405 operates from -55°C, while M22-2510405 operates from -40°C. Contact length specifications also differ slightly between the two models.

Q: Are there current rating limitations with the Harwin substitutes?

A: Yes. The MTMM-104-03-S-S-150 supports 3A total current, while both Harwin substitutes are rated at 1A per contact. Applications requiring current loads exceeding 1A per contact require the original Samtec part.

Q: Do the insulation material differences affect compatibility?

A: The MTMM-104-03-S-S-150 uses Liquid Crystal Polymer (LCP) insulation, while Harwin parts use Polyamide (PA6T) Nylon 6T. Both materials meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. Material selection depends on application-specific thermal and chemical exposure requirements.

Q: What is the maximum operating temperature for each part?

A: MTMM-104-03-S-S-150 operates to 125°C. Both M22-2010405 and M22-2510405 operate to 105°C maximum. Applications requiring sustained operation above 105°C require the Samtec part.
