M22-2010546 Equivalent & Substitute Parts

Part Overview

The M22-2010546 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole board-to-board applications. This 5-position, 2.00mm pitch connector features unshrouded male pins with solder termination and push-pull fastening. The part is currently active in production with 1670 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2010546 is determined by the following critical parameters:

• Pitch (Mating): 0.079" (2.00mm) — must match exactly for PCB footprint compatibility
• Number of Positions: 5 — electrical circuit configuration requirement
• Contact Type: Male Pin — determines mating interface
• Mounting Type: Through Hole — PCB assembly process compatibility
• Termination: Solder — assembly and reliability method
• Operating Temperature Range: Minimum -55°C ~ 105°C — thermal performance envelope
• Current Rating: Minimum 1A per Contact — electrical load capacity
• RoHS Compliance: ROHS3 Compliant — regulatory requirement

The identified substitute parts meet or exceed these core parameters. Variations in contact finish, insulation material, and stacking height do not preclude substitution when the primary electrical and mechanical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the M22-2010546.

TMM-105-01-LM-S (Samtec): This substitute provides enhanced current capacity (3.2A per Contact versus 1A) and extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C). Gold contact finish on the mating surface offers improved corrosion resistance compared to tin. The Liquid Crystal Polymer insulation material provides superior thermal and mechanical properties. This part is suitable for applications requiring higher current density or extended thermal performance.

TW-05-01-G-S-125-090 (Samtec): This substitute is a board-stacking connector with 0.125" (3.175mm) stack height and 0.090" (2.286mm) tail length. Gold contact finish is applied to the mating post. This configuration is appropriate for applications requiring vertical board-to-board spacing or multi-layer PCB stacking arrangements. Electrical and mechanical compatibility with the M22-2010546 is maintained through identical pitch, position count, and through-hole solder termination.

Selection between these substitutes depends on application-specific requirements for current capacity, thermal environment, and physical board spacing.

Frequently Asked Questions (FAQ)

Q: Can TMM-105-01-LM-S replace M22-2010546 in existing designs?

A: Yes. Both parts share identical pitch (2.00mm), position count (5), contact type (male pin), mounting method (through hole), and termination (solder). The TMM-105-01-LM-S provides higher current capacity (3.2A versus 1A per contact) and extended temperature range (-55°C ~ 125°C versus -55°C ~ 105°C), making it suitable for equivalent or more demanding applications.

Q: What is the primary difference between TMM-105-01-LM-S and TW-05-01-G-S-125-090?

A: TMM-105-01-LM-S is a standard header connector with 0.059" (1.50mm) insulation height. TW-05-01-G-S-125-090 is a board-stacking connector with 0.125" (3.175mm) stack height, designed for vertical board-to-board spacing. Both maintain 2.00mm pitch and 5-position configuration. Selection depends on whether the application requires standard header mounting or vertical stacking geometry.

Q: Are contact finish differences significant for substitution?

A: Contact finish affects corrosion resistance and mating force characteristics. M22-2010546 uses tin finish on mating contacts. Both substitutes use gold finish, which provides superior corrosion resistance and is generally preferred in high-reliability applications. Gold finish does not preclude substitution; it represents an enhancement in contact durability.

Q: Do insulation material differences affect compatibility?

A: Insulation material affects thermal stability and mechanical properties. M22-2010546 uses Polyamide (PA6T) Nylon 6T. TMM-105-01-LM-S uses Liquid Crystal Polymer (LCP), which offers superior thermal and dimensional stability. These differences do not affect electrical or mechanical compatibility at the mating interface. Material selection should be evaluated based on application thermal and mechanical requirements.

Q: Is RoHS compliance maintained across all parts?

A: Yes. M22-2010546, TMM-105-01-LM-S, and TW-05-01-G-S-125-090 are all ROHS3 Compliant, meeting current regulatory requirements for restricted substance elimination.
