M22-5320705P Equivalent & Substitute Parts

Part Overview

The M22-5320705P 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 active equivalent parts for new designs and ongoing production requirements. 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 M22-5320705P is determined by strict alignment of the following critical parameters:

Core Electrical & Mechanical Criteria:

• Number of Positions: 14
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Material: Phosphor Bronze
• Insulation Material: Polyamide or Nylon-based
• Operating Temperature: -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Acceptable Variations:

• Connector Type: Header (Cuttable or Breakaway acceptable)
• Style: Board to Board or Board to Board/Cable
• Packaging: Different packaging formats (Tape & Reel, Tube) do not affect functional compatibility
• Contact Length - Mating: Minor variations within 0.138" to 0.150" (4.60mm to 3.81mm) are acceptable for board-to-board applications
• Contact Finish Thickness - Mating: Variations in gold plating thickness do not affect substitution eligibility

Three substitute parts meet these criteria and are classified as active products.

Parameter Comparison

Engineering Selection Recommendations

M22-5320705R (Harwin Inc.) is the primary substitute for the obsolete M22-5320705P. Both parts are from the same manufacturer and M22 series, with identical electrical and mechanical specifications. The M22-5320705R is an active product available in Tape & Reel packaging, making it suitable for both prototype and production environments. This part maintains full compatibility with existing PCB designs and assembly processes.

0877591464 (Molex Milli-Grid 87759) and 0877591475 (Molex Milli-Grid 87759) are cross-manufacturer substitutes from Molex. Both parts meet all critical substitution criteria with the following considerations: contact length is 0.150" (3.81mm) versus 0.138" (4.60mm) on the original part, and insulation material includes glass-filled polyamide. Both Molex parts are active products with ROHS3 compliance and UL94 V-0 flammability rating. The primary difference between these two Molex options is packaging format (Tube versus Tape & Reel) and contact finish thickness specifications.

All three substitute parts are ROHS3 compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

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

A: Yes. M22-5320705R is functionally equivalent to M22-5320705P with identical pitch, position count, row spacing, contact type, and operating temperature range. The primary difference is product status (Active versus Obsolete) and packaging format. M22-5320705R is the recommended substitute from Harwin Inc.

Q: What is the difference between the Harwin and Molex substitutes?

A: M22-5320705R is from the same manufacturer (Harwin) and series (M22) as the original part. The Molex parts (0877591464 and 0877591475) are from a different manufacturer and series (Milli-Grid 87759) but maintain electrical and mechanical compatibility. The Molex parts have a slightly longer contact mating length (0.150" versus 0.138") and glass-filled polyamide insulation material. All three are functionally compatible for board-to-board applications.

Q: Does packaging format affect compatibility?

A: No. Packaging format (Bulk, Tape & Reel, or Tube) does not affect the functional performance or compatibility of the connector. Packaging selection is determined by production volume and assembly process requirements. M22-5320705R and 0877591475 are available in Tape & Reel format suitable for automated assembly. 0877591464 is available in Tube format.

Q: Are all substitute parts RoHS compliant?

A: Yes. M22-5320705R, 0877591464, and 0877591475 are all ROHS3 compliant, matching the compliance status of the original M22-5320705P.

Q: What is the significance of the contact length difference between Harwin and Molex parts?

A: The Molex parts have a contact mating length of 0.150" (3.81mm) compared to 0.138" (4.60mm) on the Harwin parts. This 0.012" (0.31mm) difference is within acceptable tolerance for board-to-board connector applications and does not affect mating compatibility or electrical performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, all three substitute parts are electrically and mechanically compatible for board-to-board applications. PCB footprints and mating connector designs remain compatible across all substitutes. No design modifications are required for substitution.
