Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-2740546 is determined by the following critical parameters that must remain constant:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 2A
• Operating Temperature Range: -40°C to 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: ROHS3 Compliant

The primary substitute M22-2540546 maintains all critical electrical and mechanical parameters while offering active product status and improved availability. This part is functionally equivalent for applications requiring identical mating pitch, position count, row configuration, and electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The M22-2540546 is the direct active equivalent for the obsolete M22-2740546. Both parts maintain identical electrical specifications, mechanical compatibility, and regulatory compliance. The substitute part carries active product status with confirmed inventory availability (858 pcs), ensuring long-term procurement viability.

The primary difference between these parts is the contact length at mating (0.165" vs. 0.138"), which reflects design optimization within the M22 series while maintaining full functional compatibility for standard board-to-board applications. Both parts satisfy ROHS3 compliance and UL94 V-0 flammability requirements.

Selection of M22-2540546 is appropriate for new designs and legacy system support where M22-2740546 components are no longer available.

Frequently Asked Questions (FAQ)

Q: Can M22-2540546 directly replace M22-2740546 in existing designs?

A: Yes. Both parts share identical mating pitch (2.00mm), position count (10), row configuration (2 rows), contact type (male pin), mounting style (through-hole right-angle), and electrical ratings (2A, -40°C to 105°C). The contact length difference at mating (0.165" vs. 0.138") does not affect standard board-to-board interconnect applications.

Q: What is the significance of the contact length difference?

A: The contact length at mating differs between the two parts (M22-2740546: 0.165" vs. M22-2540546: 0.138"). This variation reflects design refinement within the M22 series and does not impact electrical performance or standard mechanical compatibility for typical PCB-to-PCB connections.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both M22-2740546 and M22-2540546 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the inventory status for these parts?

A: M22-2740546 (obsolete) has 839 pcs available. M22-2540546 (active) has 858 pcs available. The active status of M22-2540546 ensures continued availability for future procurement cycles.

Q: Are there packaging differences between these parts?

A: M22-2740546 packaging is unspecified in available documentation. M22-2540546 is supplied in bulk packaging, suitable for standard component handling and assembly processes.
