M22-2742005 Equivalent & Substitute Parts

Part Overview

The M22-2742005 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board or cable applications. This 40-position connector operates at 2.00mm pitch with male pin contacts and solder termination. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the M22-2742005 is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 40
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Material: Phosphor Bronze
• Insulation Material: Polyamide (PA6T), Nylon 6T
• Operating Temperature: -40°C ~ 105°C
• Current Rating: 2A
• Material Flammability Rating: UL94 V-0

The M22-2542005 meets all substitution criteria. This part maintains identical mating pitch, position count, row configuration, contact type, mounting orientation, and termination method. Both parts share the same contact material, insulation composition, temperature range, current capacity, and flammability rating. The primary difference is product status: M22-2542005 is active production, whereas M22-2742005 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M22-2542005 is the direct substitute for the obsolete M22-2742005. Both parts are manufactured by Harwin Inc. within the M22 series and maintain full electrical and mechanical compatibility across all critical parameters. The M22-2542005 carries active product status with current manufacturing support, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The UL94 V-0 flammability rating applies to both, supporting use in safety-critical environments.

The contact length difference (0.165" versus 0.138" mating contact length) reflects design optimization in the active part but does not affect functional substitution for standard board-to-board or cable interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can M22-2542005 directly replace M22-2742005 in existing designs?

A: Yes. The M22-2542005 maintains identical mating pitch (2.00mm), position count (40), row configuration (2 rows), contact type (male pin), mounting orientation (through-hole right-angle), and termination method (solder). All electrical and mechanical parameters required for connector compatibility are equivalent.

Q: What is the primary reason for substitution?

A: The M22-2742005 is obsolete. The M22-2542005 is the active production equivalent from the same manufacturer and series, ensuring ongoing availability and supply chain support.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings. Regulatory compliance is identical.

Q: Does the contact length difference affect compatibility?

A: The mating contact length differs (0.165" versus 0.138"), but this does not impact functional compatibility for standard board-to-board or cable interconnect applications. Both parts maintain the same electrical performance and mechanical engagement characteristics required for the M22 series connector system.

Q: What packaging is available for M22-2542005?

A: M22-2542005 is supplied in bulk packaging, with 752 pieces currently in stock as new original inventory.
