M22-2740705 Equivalent & Substitute Parts

Part Overview

The M22-2740705 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board or cable applications. This 14-position connector operates at 2.00mm pitch with a 2-row configuration and supports 2A current rating across an operating temperature range of -40°C to 105°C. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M22-2740705 is determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 14
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header, Cuttable
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Current Rating: 2A
• Operating Temperature: -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The M22-2540746 meets all critical substitution criteria. Variations in contact finish (Gold Flash vs. Tin) and contact length - mating (0.165" vs. 0.138") do not prevent functional substitution when mating interface geometry is compatible with the receiving connector.

Parameter Comparison

Engineering Selection Recommendations

The M22-2540746 is the active equivalent for the obsolete M22-2740705. Both parts maintain identical electrical and mechanical specifications across pitch, position count, row configuration, current rating, and operating temperature range. Both comply with UL94 V-0 flammability requirements and ROHS3 standards.

The M22-2540746 is currently in active production status with 859 units in stock, providing supply continuity for new designs and replacement applications. The M22-2740705, classified as obsolete, should be replaced with M22-2540746 for all new procurement and design revisions.

Frequently Asked Questions (FAQ)

Q: Can M22-2540746 directly replace M22-2740705 in existing designs?

A: Yes. Both connectors share identical pitch (2.00mm), position count (14), row configuration (2 rows), mounting type (through-hole right-angle), and current rating (2A). The contact length difference (0.165" vs. 0.138" mating length) requires verification that the receiving connector socket depth accommodates the substitute part's contact geometry.

Q: What is the difference between Gold Flash and Tin contact finishes?

A: Contact finish affects corrosion resistance and mating force characteristics. Gold Flash provides superior corrosion resistance in high-humidity environments. Tin offers adequate performance in standard industrial conditions. Selection depends on application environment and mating cycle requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both M22-2740705 and M22-2540746 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is M22-2740705 classified as obsolete?

A: Harwin Inc. has discontinued the M22-2740705 in favor of the M22-2540746, which maintains functional equivalence while offering improved supply availability and active production support.
