M22-2010905 Equivalent & Substitute Parts

Part Overview

The M22-2010905 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole board-to-board applications. This 9-position, single-row connector operates at 0.079" (2.00mm) pitch and supports 1A per contact with an operating temperature range of -55°C to 105°C. The part is currently active in production with ROHS3 compliance and UL94 V-0 flammability rating. 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 inventory constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2010905 is determined by the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — must match exactly for mechanical compatibility
• Number of Positions: 9 — connector must accommodate identical pin count
• Contact Type: Male Pin — gender must remain consistent
• Mounting Type: Through Hole — PCB mounting method must be identical
• Termination: Solder — connection method must match
• Current Rating: Minimum 1A per Contact — substitute must meet or exceed current capacity
• Operating Temperature Range: Minimum -55°C ~ 105°C — substitute must cover or exceed this range
• Contact Finish - Mating: Gold — ensures equivalent electrical performance and corrosion resistance

Two substitute parts meet these criteria: TMM-109-01-L-S (Samtec Inc.) and TW-09-02-L-S-140-095 (Samtec Inc.). Both maintain the 2.00mm pitch, 9-position configuration, male pin contact type, through-hole mounting, and solder termination. Both are ROHS3 compliant and feature gold-plated mating contacts.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance, meeting regulatory requirements equivalent to the M22-2010905.

TMM-109-01-L-S (Samtec Inc.) exceeds the original specification in current rating (3.2A per contact versus 1A) and operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C). The insulation material differs (Liquid Crystal Polymer versus Polyamide), and contact finish thickness on the mating surface is specified (10.0µin / 0.25µm). This part is suitable for applications requiring higher current capacity or extended temperature operation.

TW-09-02-L-S-140-095 (Samtec Inc.) is a board stack connector with specified stack height (0.140" / 4.656mm) and tail length (0.095" / 2.413mm). This configuration is designed for stacked board applications where vertical spacing and solder tail geometry are critical design parameters. Detailed current and temperature specifications are not provided for this variant.

Selection between substitutes depends on application requirements: TMM-109-01-L-S for standard board-to-board applications with enhanced electrical margins, or TW-09-02-L-S-140-095 for multi-board stacking configurations.

Frequently Asked Questions (FAQ)

Q: Can TMM-109-01-L-S be used as a direct replacement for M22-2010905?

A: Yes, within the specified electrical and mechanical parameters. Both connectors share identical pitch (2.00mm), position count (9), contact type (male pin), mounting method (through hole), and termination (solder). TMM-109-01-L-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 applications within the original operating envelope.

Q: What is the difference between TMM-109-01-L-S and TW-09-02-L-S-140-095?

A: TMM-109-01-L-S is a standard header connector for board-to-board or cable applications. TW-09-02-L-S-140-095 is a board stack connector with defined stack height (4.656mm) and solder tail length (2.413mm), designed for applications requiring multiple stacked PCBs. The choice depends on whether your application uses single-board or multi-board configurations.

Q: Are all three parts RoHS compliant?

A: Yes. M22-2010905, TMM-109-01-L-S, and TW-09-02-L-S-140-095 are all ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: What is the contact finish thickness specification for the M22-2010905?

A: Contact finish thickness for the mating surface is not specified in the M22-2010905 datasheet. TMM-109-01-L-S specifies 10.0µin (0.25µm) gold plating on the mating contact, providing a reference for equivalent gold plating thickness in substitute applications.

Q: Can I use TW-09-02-L-S-140-095 in a single-board application?

A: TW-09-02-L-S-140-095 is designed for board stacking applications with specific stack height and tail geometry. While the 2.00mm pitch and 9-position configuration match the M22-2010905, the stack height (4.656mm) and tail length (2.413mm) are optimized for multi-board configurations. Use in single-board applications requires verification that the connector geometry does not conflict with PCB layout constraints.
