M22-2030705 Equivalent & Substitute Parts
Part Overview
The M22-2030705 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board applications with 7 positions at 2.00mm pitch. This connector features male pins with gold-plated mating contacts, phosphor bronze material, and operates across -55°C to 105°C. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility with the 2.00mm pitch, 7-position configuration, through-hole right-angle mounting, and solder termination while meeting equivalent electrical and mechanical specifications.

Engineering Selection Recommendations
M22-2030746 (Harwin Inc., Active Status)
M22-2030746 is the manufacturer-recommended direct substitute for M22-2030705. Both parts share identical mechanical and electrical specifications with the exception of contact finish: M22-2030746 features tin-plated mating contacts versus the gold plating of the original. This substitution is valid for applications where tin plating provides equivalent corrosion resistance and electrical conductivity. The part maintains ROHS3 compliance, UL94 V-0 flammability rating, and identical operating temperature range. Active product status ensures long-term availability and supply chain continuity.
NRPN071PARN-RC (Sullins Connector Solutions, Active Status)
NRPN071PARN-RC is a cross-manufacturer equivalent from Sullins Connector Solutions. This part maintains all critical compatibility parameters: 2.00mm pitch, 7 positions, through-hole right-angle mounting, and solder termination. The contact material differs (brass versus phosphor bronze) and current rating is elevated to 2A per contact. Operating temperature range is -40°C to 105°C, which covers the original specification. ROHS3 compliance and UL94 V-0 flammability rating are maintained. Gold plating on mating contacts matches the original M22-2030705 specification. This part is suitable for applications requiring cross-manufacturer sourcing flexibility.
TMM-107-01-F-S-RA Series (Samtec Inc., Active Status)
The Samtec TMM-107-01-F-S-RA and its variants (TMM-107-01-F-S-RA-001 through TMM-107-01-F-S-RA-007) represent alternative solutions from Samtec Inc. These parts maintain all critical compatibility parameters and offer enhanced specifications: operating temperature range extends to -55°C to 125°C, and current rating is 3.2A per contact. Insulation material is Liquid Crystal Polymer (LCP) instead of polyamide, providing superior thermal and mechanical properties. Gold plating on mating contacts matches the original specification. ROHS3 compliance is maintained. The variants TMM-107-01-F-S-RA-001 through 007 differ only in number of positions loaded (6 positions versus 7), making them suitable for applications requiring partial position loading. All Samtec variants are active products with consistent inventory availability.
Frequently Asked Questions (FAQ)
Q: Can M22-2030746 be used as a direct replacement for M22-2030705?
A: Yes. M22-2030746 is the manufacturer-recommended substitute. The only difference is contact finish (tin versus gold). Both parts meet identical mechanical, electrical, and compliance specifications. The tin finish provides equivalent corrosion resistance and electrical conductivity for standard applications.
Q: What is the key difference between the original M22-2030705 and NRPN071PARN-RC?
A: The primary differences are contact material (brass versus phosphor bronze) and current rating (2A versus 1A per contact). All critical compatibility parameters—pitch, position count, mounting type, and termination—are identical. NRPN071PARN-RC is suitable for applications requiring higher current capacity or cross-manufacturer sourcing.
Q: Are the Samtec TMM-107 variants fully compatible with M22-2030705?
A: Yes, the TMM-107-01-F-S-RA and its variants maintain all critical compatibility parameters. The variants TMM-107-01-F-S-RA-001 through 007 differ only in the number of positions loaded (6 versus 7). Select TMM-107-01-F-S-RA for full 7-position loading or the numbered variants if 6-position loading is acceptable for your application.
Q: Why do some substitute parts have higher current ratings?
A: NRPN071PARN-RC (2A) and Samtec TMM-107 series (3.2A) have higher current ratings due to differences in contact material and design. These higher ratings are acceptable substitutes for the original 1A specification, as they exceed the electrical requirements. Applications requiring only 1A per contact can safely use these parts.
Q: What is the operating temperature difference between M22-2030705 and the Samtec alternatives?
A: M22-2030705 operates from -55°C to 105°C. Samtec TMM-107 series extends the upper limit to 125°C. This extended range is acceptable for applications within the original specification range and provides additional thermal margin for demanding environments.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. M22-2030746, NRPN071PARN-RC, and all Samtec TMM-107 variants are ROHS3 compliant, matching the original M22-2030705 specification.
Q: What is the difference between TMM-107-01-F-S-RA and TMM-107-01-F-S-RA-001 through 007?
A: TMM-107-01-F-S-RA has all 7 positions loaded. Variants TMM-107-01-F-S-RA-001 through 007 have 6 positions loaded. Select based on your application's position requirements. All other electrical and mechanical specifications are identical.
Q: Can I mix substitute parts from different manufacturers in the same application?
A: All substitute parts maintain identical pitch, position count, mounting type, and termination specifications. However, for consistency in production and maintenance, it is preferable to standardize on a single substitute part number per application.
