M22-2030546 Equivalent & Substitute Parts

Part Overview

The M22-2030546 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board applications with 5 positions at 2.00mm pitch. This connector features male pins with tin contact finish, phosphor bronze material, and operates across -55°C to 105°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain electrical compatibility through matching pitch, position count, contact type, and current rating specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

Pitch - Mating: 0.079" (2.00mm) — mechanical and electrical interface requirement
Number of Positions: 5 — PCB footprint compatibility
Number of Rows: 1 — board layout constraint
Contact Type: Male Pin — mating interface specification
Mounting Type: Through Hole, Right Angle — assembly and orientation requirement
Termination: Solder — assembly process compatibility
Insulation Height: 0.079" (2.00mm) — clearance and stacking requirement

Acceptable Variation Parameters:

Contact Finish (Mating): Tin or Gold — both provide adequate electrical conductivity
Current Rating: Substitute parts rated at 3.2A per contact exceed the 1A requirement and remain compatible
Operating Temperature: Substitute parts rated to 125°C exceed the -55°C to 105°C requirement and remain compatible
Insulation Material: LCP (Liquid Crystal Polymer) substitutes for PA6T/Nylon 6T with equivalent electrical and mechanical properties
Number of Positions Loaded: Partial loading (4 positions) in some substitutes does not affect full 5-position functionality

All listed substitute parts meet these criteria and maintain functional equivalence for the M22-2030546 application.

Engineering Selection Recommendations

Primary Recommendation: M22-2030505

M22-2030505 is the manufacturer-recommended direct substitute from Harwin Inc. It maintains identical electrical and mechanical specifications to the M22-2030546 while offering active product status. The primary difference is the contact finish upgrade from tin to gold, which provides enhanced corrosion resistance and contact reliability. This part is suitable for direct replacement in existing designs without PCB modification.

Alternative Recommendations: Samtec TMM Series

The Samtec TMM-105 series (TMM-105-01-F-S-RA, TMM-105-01-G-S-RA, TMM-105-01-FM-S-RA) provides cross-manufacturer equivalence with enhanced electrical performance. These parts exceed the original specifications with 3.2A per contact current rating and -55°C to 125°C operating temperature range. The TMM series uses Liquid Crystal Polymer insulation material, which offers superior dimensional stability compared to polyamide. All TMM variants maintain ROHS3 compliance and are actively produced.

Selection Criteria:

For direct Harwin ecosystem compatibility: Select M22-2030505
For enhanced current capacity and temperature range: Select TMM-105-01-F-S-RA or TMM-105-01-G-S-RA
For full position loading with gold finish: Select TMM-105-01-G-S-RA or TMM-105-01-FM-S-RA

All recommended substitutes are ROHS3 compliant and MSL 1 rated, meeting regulatory and moisture sensitivity requirements equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can M22-2030505 be used as a direct replacement for M22-2030546?

A: Yes. M22-2030505 is the manufacturer-recommended substitute with identical pitch (2.00mm), position count (5), mounting type (through-hole right-angle), and termination (solder). The contact finish upgrade from tin to gold does not affect mechanical compatibility. No PCB redesign is required.

Q: What is the difference between Harwin M22-2030505 and Samtec TMM-105-01-F-S-RA?

A: Both parts share identical pitch, position count, and mounting specifications. Key differences include: Samtec TMM series offers 3.2A per contact versus 1A for the Harwin part, operating temperature to 125°C versus 105°C, and Liquid Crystal Polymer insulation versus polyamide. These represent performance enhancements rather than incompatibilities.

Q: Are TMM-105-01-F-S-RA and TMM-105-01-G-S-RA interchangeable?

A: Yes, for electrical and mechanical function. Both maintain 0.079" (2.00mm) pitch, 5 positions, and through-hole right-angle mounting. The primary difference is contact finish: TMM-105-01-F-S-RA has gold mating surface with tin post finish, while TMM-105-01-G-S-RA has gold on both mating surface and post. Select based on corrosion environment requirements.

Q: What does "Number of Positions Loaded" mean in the TMM series?

A: This indicates how many of the 5 available positions are populated with contacts in the connector body. Parts marked "All" have all 5 positions loaded. Parts marked "4" have 4 positions loaded. For applications requiring all 5 positions, select parts with "All" loading (TMM-105-01-F-S-RA, TMM-105-01-G-S-RA, TMM-105-01-FM-S-RA).

Q: Is the higher current rating of TMM series parts (3.2A vs 1A) a concern for M22-2030546 applications?

A: No. Higher current rating indicates greater capacity and does not affect compatibility. If the original application operates at 1A per contact, the TMM series rated at 3.2A per contact will function identically with improved margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. M22-2030505 and all Samtec TMM-105 variants listed are ROHS3 compliant. All parts are also MSL 1 rated (unlimited moisture sensitivity level), matching the original M22-2030546 specification.

Q: Can I mix Harwin and Samtec connectors in the same application?

A: Yes, provided they are used in separate connector positions. All listed parts maintain identical pitch, position spacing, and mating interface specifications. However, for consistency in procurement and assembly, using a single manufacturer across an application is recommended.
