Harwin M22-2011005 Equivalent & Substitute Parts

Part Overview

The Harwin M22-2011005 is a rectangular connector header designed for through-hole mounting applications. This 10-position, 2.00mm pitch connector features male pins with gold-plated mating contacts and is rated for 1A per contact at operating temperatures from -55°C to 105°C. The part is currently active in production and ROHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's core specifications, enabling direct replacement in board-to-board or cable connection applications while maintaining design integrity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M22-2011005 are qualified based on the following critical parameters that determine functional equivalence:

• 10-position connector configuration
• 0.079" (2.00mm) mating pitch
• Male pin contact type
• Through-hole solder termination
• Gold-plated mating contact finish
• Phosphor bronze contact material
• Operating temperature range compatibility (-55°C minimum and 105°C maximum or higher)
• ROHS3 compliance and MSL 1 rating
• Board-to-board or cable connection style

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in insulation material (LCP vs. Nylon 6T), contact length dimensions, current rating capacity, and post finish do not preclude substitution when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements. The Samtec MTMM-110-03-L-S-150 and TMM series parts offer extended operating temperature ranges (-55°C to 125°C) compared to the M22-2011005 (-55°C to 105°C), providing additional thermal margin in applications requiring higher temperature performance.

The Samtec TW series parts (TW-10-01-L-S-128-073 and TW-10-01-T-S-160-080) are board stacking connectors with defined stack heights and tail lengths, suitable for applications requiring specific vertical spacing or multi-board configurations. The TW-10-01-L-S-128-073 maintains gold plating on mating contacts, while TW-10-01-T-S-160-080 uses tin plating.

Selection among substitute parts should be based on specific application requirements including thermal environment, current demands, and mechanical form factor constraints. All parts share the core 10-position, 2.00mm pitch configuration and through-hole solder termination required for direct functional replacement.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MTMM-110-03-L-S-150 directly replace the Harwin M22-2011005?

A: Yes. Both parts share the same 10-position, 2.00mm pitch configuration, male pin contact type, gold-plated mating finish, phosphor bronze contact material, through-hole solder termination, and ROHS3 compliance. The MTMM variant uses LCP insulation instead of Nylon 6T and supports higher current (3A vs. 1A) and extended temperature range (-55°C to 125°C vs. -55°C to 105°C).

Q: What is the difference between the TMM-110-01-L-S and TMM-110-01-LM-S?

A: Both parts are electrically and mechanically equivalent. The TMM-110-01-LM-S is designated as a 2MM terminal strip variant but maintains identical electrical specifications, contact dimensions, and performance characteristics as the TMM-110-01-L-S.

Q: Are the Samtec TW series parts suitable for the same applications as the M22-2011005?

A: The TW series parts are board stacking connectors with defined stack heights and tail lengths. They are suitable for applications requiring specific vertical spacing between boards. The TW-10-01-L-S-128-073 (gold plating) and TW-10-01-T-S-160-080 (tin plating) both maintain the 10-position, 2.00mm pitch configuration and through-hole solder termination. Selection depends on whether the application requires the specific stack height and tail length characteristics of the TW series.

Q: What is the impact of insulation material differences between Nylon 6T and LCP?

A: The M22-2011005 uses Polyamide (PA6T) Nylon 6T insulation, while the Samtec MTMM and TMM series use Liquid Crystal Polymer (LCP). Both materials are UL94 V-0 rated or equivalent and suitable for standard through-hole connector applications. LCP offers improved dimensional stability and higher temperature performance, which is reflected in the extended operating temperature range of the Samtec parts.

Q: Can I use the TW-10-01-T-S-160-080 with tin plating instead of the gold-plated alternatives?

A: The TW-10-01-T-S-160-080 uses tin plating on mating contacts instead of gold. Tin plating is suitable for standard connector applications but may have different contact resistance and corrosion characteristics compared to gold plating. Application-specific requirements for contact reliability and environmental exposure should be evaluated before selecting tin-plated alternatives.

Q: Are all substitute parts available in the same packaging format?

A: All listed parts are supplied in bulk packaging, matching the M22-2011005 packaging format. Inventory availability varies by part number and supplier.
