M22-2412146 Equivalent & Substitute Parts

Part Overview

The M22-2412146 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board or cable applications. This 42-position connector operates at 2A per contact with a 2.00mm pitch and features tin-plated copper alloy contacts in an unshrouded configuration. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution for the M22-2412146 is determined by strict equivalence across the following critical parameters:

Connector geometry: 42 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
Mounting configuration: Through-hole, right-angle orientation
Contact system: Male pin, solder termination, push-pull fastening
Electrical performance: Current rating and contact material compatibility
Environmental compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The substitute parts 58102-G61-21LF (Amphenol ICC) and 951242-7622-AR (3M) meet these core substitution criteria. Both maintain the same connector geometry, mounting type, contact configuration, and compliance certifications as the original M22-2412146.

Engineering Selection Recommendations

58102-G61-21LF (Amphenol ICC Minitek®): This substitute maintains full electrical and mechanical compatibility with the M22-2412146. The part is active in production with RoHS compliance and MSL 1 rating. The gold-plated mating contacts provide enhanced corrosion resistance compared to the tin finish of the original part. Current rating of 2A per contact matches the original specification. This part is suitable for direct substitution in new designs and production continuity applications.

951242-7622-AR (3M Series 951): This substitute meets the core geometric and mechanical requirements with identical 42-position, 2-row, 2.00mm pitch configuration. The part is active with RoHS compliance and MSL 1 rating. Operating temperature range extends to -55°C ~ 125°C, providing broader environmental capability than the original. However, the current rating is specified at 1A, which is lower than the original 2A per contact specification. This part is suitable for applications where the reduced current rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 58102-G61-21LF directly replace M22-2412146 in existing designs? A: Yes. The 58102-G61-21LF maintains identical connector geometry (42 positions, 2 rows, 2.00mm pitch), mounting configuration (through-hole, right-angle), and electrical performance (2A per contact). Physical dimensions of mating and post contacts differ slightly, but these variations remain within acceptable mechanical tolerance for board-to-board applications.

Q: What is the key difference between the two substitute parts? A: The primary difference is current rating. The 58102-G61-21LF maintains the original 2A per contact specification, while the 951242-7622-AR is rated at 1A per contact. Contact finish also differs: 58102-G61-21LF uses gold plating, while 951242-7622-AR uses gold with tin-plated posts. Operating temperature range for 951242-7622-AR extends to -55°C ~ 125°C versus -40°C ~ 105°C for the original.

Q: Are both substitutes RoHS compliant? A: Yes. Both 58102-G61-21LF and 951242-7622-AR are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the original M22-2412146.

Q: Which substitute should be selected for high-current applications? A: The 58102-G61-21LF is the appropriate choice for applications requiring 2A per contact current capacity. The 951242-7622-AR, rated at 1A per contact, is suitable only for lower-current applications.

Q: Are there mechanical fit considerations when substituting? A: Minor variations exist in contact length and insulation height across the three parts. The 58102-G61-21LF has a post length of 0.098" (2.50mm) compared to 0.110" (2.79mm) for both the original and 951242-7622-AR. Insulation heights also vary slightly. These differences are within standard connector tolerance ranges for push-pull fastening systems and do not affect mating compatibility.
