M22-2740346 Equivalent & Substitute Parts

Part Overview

The M22-2740346 is a rectangular connector header manufactured by Harwin Inc., designed for through-hole, right-angle board-to-board or cable applications. This 6-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 functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-2740346 is determined by the following critical parameters:

• Manufacturer series compatibility (M22 series)
• Mating pitch specification (0.079" / 2.00mm)
• Connector type classification (Header, Cuttable)
• Mounting configuration (Through Hole, Right Angle)
• Contact type (Male Pin)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Operating temperature range (-40°C to 105°C minimum)
• Current rating (2A minimum)
• Material flammability rating (UL94 V-0)
• RoHS3 compliance status

The substitute part M22-2540205 shares the same series, pitch, connector type, mounting configuration, contact type, termination method, fastening type, operating temperature range, current rating, and flammability rating. The primary difference is the number of positions (4 versus 6), which represents a functional reduction in connector capacity rather than an incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The M22-2540205 is an active product within the same M22 series and maintains full electrical and mechanical compatibility with the M22-2740346 across all critical parameters: pitch, mounting type, contact configuration, operating temperature, current rating, and regulatory compliance (UL94 V-0, RoHS3, REACH Unaffected).

Selection of M22-2540205 as a substitute is appropriate when circuit design accommodates a 4-position connector in place of the original 6-position configuration. The reduced position count does not affect electrical performance, thermal characteristics, or compliance certifications. The active product status of M22-2540205 ensures ongoing availability and supply chain stability compared to the obsolete M22-2740346.

Frequently Asked Questions (FAQ)

Q: Can M22-2540205 directly replace M22-2740346 in existing designs?

A: Direct replacement is possible only if the circuit design requires 4 or fewer signal connections. The M22-2540205 provides identical electrical performance and mechanical interface within its 4-position capacity. PCB layout modifications may be required to accommodate the reduced connector footprint.

Q: What is the primary difference between these two connectors?

A: The M22-2740346 provides 6 positions in a 2-row configuration, while the M22-2540205 provides 4 positions in a 2-row configuration. All other electrical, mechanical, and environmental specifications remain identical.

Q: Are there any compliance or certification differences?

A: Both connectors maintain identical compliance status: UL94 V-0 flammability rating, RoHS3 compliance, and REACH Unaffected designation. No compliance trade-offs exist between the two parts.

Q: Why is M22-2740346 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Harwin Inc. The M22-2540205, as an active product within the same series, represents the current manufacturing alternative for applications requiring 2.00mm pitch, right-angle header connectors.

Q: Does contact finish differ between these parts?

A: Yes. The M22-2740346 features tin contact finish on both mating and post surfaces. The M22-2540205 features gold contact finish on mating surfaces. Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance within the specified current and temperature ratings.

Q: Are packaging considerations relevant to substitution?

A: The M22-2740346 is packaged as individual units, while M22-2540205 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it is a procurement and logistics consideration only.
