M22-5320705 Equivalent & Substitute Parts

Part Overview

The M22-5320705 is a surface mount rectangular connector header manufactured by Harwin Inc., featuring 14 positions arranged in 2 rows with 0.079" (2.00mm) pitch. This connector is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part is designed for board-to-board applications with solder termination and push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-5320705 is determined by 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)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Type: Male Pin
• Insulation Height: 0.059" (1.50mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must maintain identical or functionally equivalent values across all critical parameters. Variations in packaging format (bulk vs. tape & reel), connector type designation (cuttable vs. breakaway), and contact length specifications within acceptable tolerances do not preclude substitution when all core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The M22-5320705 is classified as obsolete. Three active substitute parts are available:

M22-5320705R (Harwin Inc.) is the direct equivalent from the original manufacturer. This part maintains identical electrical and mechanical specifications, including contact length, insulation height, and material composition. The primary difference is packaging format (tape & reel vs. bulk) and active product status. This part is the preferred substitute for direct replacement in new procurement.

0877591464 (Molex, Milli-Grid 87759 Series) and 0877591475 (Molex, Milli-Grid 87759 Series) are functionally equivalent alternatives from Molex. Both parts maintain the same pitch, position count, row configuration, mounting type, and termination method. The contact length specification differs slightly (0.150" vs. 0.138"), representing a 0.011" increase. Both parts carry active product status, ROHS3 compliance, and UL94 V-0 flammability rating. The Molex parts are designated as breakaway headers rather than cuttable, and are packaged in tube (0877591464) or tape & reel (0877591475) formats.

All three substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can M22-5320705R be used as a direct replacement for M22-5320705?

A: Yes. M22-5320705R is the active equivalent from Harwin Inc. with identical electrical and mechanical specifications. The only differences are packaging format and product status (active vs. obsolete).

Q: What is the difference between the Harwin and Molex substitute options?

A: M22-5320705R is the original manufacturer's active equivalent. The Molex parts (0877591464 and 0877591475) are functionally equivalent alternatives from a different manufacturer. All three maintain the same pitch, position count, row spacing, and core electrical parameters. The Molex parts feature a slightly longer contact length (0.150" vs. 0.138") and are designated as breakaway rather than cuttable headers.

Q: Does the contact length difference between Harwin and Molex parts affect compatibility?

A: The contact length difference (0.011") is within typical tolerance ranges for board-to-board connector applications. Both specifications meet the same mating interface requirements. Compatibility depends on the specific mating connector design in your application.

Q: Which packaging format should I select?

A: Packaging selection depends on procurement volume and assembly process. Tape & reel (TR) packaging is standard for high-volume automated assembly. Tube packaging is suitable for lower volumes or manual assembly. Bulk packaging is used for component kits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. M22-5320705R, 0877591464, and 0877591475 are all ROHS3 compliant with REACH unaffected status and MSL 1 rating.

Q: Can I mix Harwin and Molex connectors in the same application?

A: Mixing manufacturers is not recommended within a single mating pair. Select one manufacturer's connector and its corresponding mating connector to ensure optimal contact engagement and performance.
