Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-2741646 is determined by strict equivalence across the following critical parameters:

• Pitch and row spacing: 0.079" (2.00mm) mating pitch with 0.079" row spacing
• Position count and configuration: 32 positions in 2-row arrangement
• Connector type: Header, cuttable, male pin contact
• Mounting: Through-hole, right-angle orientation
• Electrical performance: 2A current rating
• Temperature range: -40°C to 105°C operation
• Compliance: ROHS3 and REACH requirements
• Series family: M22 rectangular connector series

The M22-2541605 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share identical pitch, position count, row configuration, mounting type, current rating, and operating temperature range. Both are ROHS3 compliant and REACH unaffected.

Parameter Comparison

Engineering Selection Recommendations

The M22-2541605 is the active equivalent for the obsolete M22-2741646. Both parts maintain identical mechanical and electrical specifications across all critical parameters including pitch, position count, row configuration, mounting orientation, current rating, and operating temperature range.

The M22-2541605 carries active product status, ensuring ongoing availability and manufacturing support. Both parts meet ROHS3 compliance and REACH requirements, suitable for applications requiring regulatory adherence.

Minor differences exist in contact finish (gold versus tin on mating surfaces) and contact length on mating surfaces (0.138" versus 0.165"). These variations do not affect functional compatibility for standard board-to-board or cable connection applications within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can M22-2541605 directly replace M22-2741646 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (32), row configuration (2 rows), mounting type (through-hole right-angle), current rating (2A), and operating temperature range (-40°C to 105°C). Mechanical and electrical compatibility is maintained.

Q: What is the difference between tin and gold contact finishes?

A: Contact finish affects corrosion resistance and contact reliability. Gold provides superior corrosion resistance in harsh environments, while tin is suitable for standard applications. Both finishes support the 2A current rating and operate across the specified temperature range.

Q: Are there packaging differences between these parts?

A: M22-2741646 packaging is not specified in available data. M22-2541605 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M22-2741646 and M22-2541605 are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability rating with MSL 1 (unlimited) moisture sensitivity level.

Q: Why is M22-2741646 listed as obsolete?

A: Product obsolescence typically reflects manufacturing discontinuation. The M22-2541605 serves as the active production equivalent, ensuring continued availability for new designs and ongoing support.
