Substitute Part Grouping Explanation

Substitute parts for the M22-2524005 are qualified based on the following critical parameters that determine functional interchangeability:

Position Count & Pitch: 80 positions at 0.079" (2.00mm) mating pitch and 0.079" (2.00mm) row spacing
Contact Configuration: Male pin, square contact shape, gold-plated mating surface
Mounting & Termination: Through-hole solder termination for board-to-board applications
Current Capacity: 1A per contact minimum
Environmental Compliance: RoHS3 compliance and UL94 V-0 flammability rating

The identified substitutes maintain these core parameters while allowing variations in contact length, overall connector height, insulation material composition, and operating temperature range, provided the mating interface and electrical characteristics remain compatible.

Engineering Selection Recommendations

All three parts maintain active production status and meet RoHS3 compliance requirements. The M22-2524005 and 951280-8622-AR are functionally equivalent headers with matching position counts, pitch, and contact configuration. The 951280-8622-AR offers an extended operating temperature range (-55°C ~ 125°C) compared to the M22-2524005 (-40°C ~ 105°C), making it suitable for applications requiring broader thermal performance.

The TW-40-06-G-D-125-190 from Samtec is a board-stacking connector with significantly longer overall contact length (0.673" vs. 0.287"), designed for applications requiring increased mating height and multiple board-to-board stacking configurations. This part is not a direct pin-for-pin replacement but serves specialized stacking applications where the extended contact length is a functional requirement.

Selection between M22-2524005 and 951280-8622-AR should be based on operating temperature requirements and supply chain availability. The TW-40-06-G-D-125-190 should be selected only when board stacking height and extended contact length are design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 951280-8622-AR directly replace the M22-2524005?

A: Yes. Both connectors share identical position count (80), pitch (0.079"), row configuration (2 rows), contact type (male pin), and mating surface finish (gold). The primary difference is the extended operating temperature range of the 951280-8622-AR (-55°C ~ 125°C vs. -40°C ~ 105°C). Direct substitution is valid for applications within the M22-2524005 temperature specification.

Q: What is the primary difference between the M22-2524005 and TW-40-06-G-D-125-190?

A: The TW-40-06-G-D-125-190 is a board-stacking connector with a stack height of 0.125" (3.175mm) and overall contact length of 0.673" (17.094mm), compared to the M22-2524005 standard header with 0.287" (7.30mm) overall contact length. The Samtec part is designed for applications requiring multiple board-to-board interconnections with increased vertical spacing.

Q: Are all three parts RoHS compliant?

A: Yes. The M22-2524005 and TW-40-06-G-D-125-190 are ROHS3 compliant. The 951280-8622-AR is RoHS compliant. All three parts meet regulatory requirements for restricted substance elimination.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: The 951280-8622-AR supports operating temperatures up to 125°C, making it suitable for high-temperature applications. The M22-2524005 is rated to 105°C maximum. The TW-40-06-G-D-125-190 does not specify an operating temperature range. Part selection should match the application's thermal requirements.
