Engineering Selection Recommendations
The 3M 951222-8622-AR connector is the designated substitute for the obsolete M22-2721146. This substitution is supported by:
- Identical pitch (2.00mm) and position count (22 positions, 2 rows)
- Matching through-hole solder termination configuration
- Active product status ensuring ongoing availability and supply chain continuity
- RoHS compliance and REACH unaffected status, maintaining regulatory alignment with the original component
- MSL 1 rating providing equivalent moisture handling characteristics
- Identical ECCN and HTSUS classifications
The substitute part maintains full functional and mechanical compatibility for board-level integration without requiring PCB redesign.
Frequently Asked Questions (FAQ)
Q: Can the 951222-8622-AR directly replace the M22-2721146 without PCB modification?
A: Yes. Both connectors share identical pitch (2.00mm), position count (22), row configuration (2 rows), and through-hole solder termination. Direct substitution is possible without PCB layout changes.
Q: What is the primary reason for substitution?
A: The M22-2721146 is classified as Obsolete. The 951222-8622-AR is an Active product, ensuring long-term availability and supply chain reliability.
Q: Are there compliance differences between the two parts?
A: Both parts maintain RoHS compliance and REACH unaffected status. The M22-2721146 is ROHS3 compliant, while the 951222-8622-AR is RoHS compliant. Both carry MSL 1 ratings. No compliance barriers exist for substitution.
Q: What are the key electrical parameters of the substitute?
A: The 951222-8622-AR is rated for 1A current at operating temperatures from -55°C to 125°C. Contact finish is gold on mating surfaces with copper alloy material composition.
Q: Is the packaging format different?
A: The M22-2721146 packaging is not specified in available data. The 951222-8622-AR is supplied in Bulk packaging. Confirm packaging requirements for your procurement process.
Q: Are there any mechanical differences in connector geometry?
A: Both connectors are unshrouded headers with identical pitch and position spacing. The 951222-8622-AR specifies contact length (mating: 4.40mm, post: 2.79mm) and insulation height (1.52mm). Verify these dimensions against your PCB design requirements.
