Harwin M22-5322246 Equivalent & Substitute Parts

Part Overview

The Harwin M22-5322246 is a rectangular connector header designed for surface mount applications with 44 positions at 2.00mm pitch. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The M22 series provides board-to-board connectivity with cuttable header configuration and push-pull fastening. Locating functionally equivalent alternatives ensures design flexibility and supply chain reliability for applications requiring this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-5322246 is determined by strict alignment with the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 44
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Type: Male Pin
• Insulation Material: Polyamide or Nylon-based
• Operating Temperature Range: -40°C ~ 105°C minimum
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional compatibility in board-to-board applications. Variations in contact finish (tin versus gold), connector style (cuttable versus breakaway), and contact length tolerances are within acceptable engineering parameters for equivalent substitution.

Parameter Comparison

Engineering Selection Recommendations

The M22-5322205 from Harwin Inc. is the primary equivalent for the obsolete M22-5322246. Both components share identical pitch, position count, row configuration, and operating temperature specifications. The M22-5322205 maintains active product status with ROHS3 compliance and UL94 V-0 flammability rating. The primary difference is contact finish (gold versus tin), which provides enhanced corrosion resistance in the active part. This component is available in bulk packaging.

The Molex 0877597644 (Milli-Grid 87759 series) provides a secondary equivalent option with matching pitch, position count, and row spacing. This part features a breakaway connector style rather than cuttable configuration and includes board guide and pick-and-place features. Contact length is 0.150" (3.81mm) compared to 0.138" (4.60mm) in the main part, representing a 0.011" (0.31mm) difference. The Molex part is supplied in Tape & Reel packaging and maintains ROHS3 compliance and UL94 V-0 rating. Operating temperature and current rating specifications are not provided for this component.

Both substitute parts satisfy the core electrical and mechanical requirements for board-to-board connectivity at 2.00mm pitch with 44 positions in a 2-row configuration.

Frequently Asked Questions (FAQ)

Q: Can M22-5322205 directly replace M22-5322246 in existing designs?

A: Yes. The M22-5322205 maintains identical pitch (2.00mm), position count (44), row configuration (2 rows), mounting type (surface mount), and operating temperature range (-40°C ~ 105°C). The primary difference is contact finish (gold versus tin), which does not affect functional compatibility. Both components use phosphor bronze contacts and polyamide insulation materials.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish affects corrosion resistance and long-term reliability. Gold plating provides superior corrosion resistance compared to tin, particularly in humid or corrosive environments. The choice between tin and gold finishes depends on application requirements and environmental exposure conditions.

Q: Is the Molex 0877597644 compatible with designs using the M22-5322246?

A: The Molex part maintains electrical compatibility through matching pitch, position count, and row spacing. However, the contact length difference (0.150" versus 0.138") and connector style variation (breakaway versus cuttable) require mechanical verification. The breakaway configuration may affect board layout and assembly procedures compared to the cuttable design.

Q: What packaging options are available for these substitute parts?

A: M22-5322205 is supplied in bulk packaging. The Molex 0877597644 is supplied in Tape & Reel (TR) format, which is suitable for automated assembly processes.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both M22-5322205 and 0877597644 maintain ROHS3 compliance and UL94 V-0 flammability rating, matching the compliance profile of the original M22-5322246.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts (M22-5322246, M22-5322205, and 0877597644) have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
