Substitute Part Grouping Explanation
The M22-7141142 is identified as a manufacturer-recommended substitute for the M22-7132142. Substitution eligibility is determined by the following critical parameters:
Matching Parameters:
- Manufacturer: Harwin Inc. (same family)
- Series: M22 (same connector series)
- Connector Type: Receptacle (same functional type)
- Contact Type: Female Socket (same contact configuration)
- Pitch - Mating: 0.079" (2.00mm) (identical spacing)
- Mounting Type: Through Hole (same PCB integration method)
- Termination: Solder (same connection method)
- Fastening Type: Push-Pull (same mating mechanism)
- Contact Finish - Mating: Gold (same contact surface)
- Current Rating: 2A (same electrical capacity)
- Voltage Rating: 500VAC (same voltage specification)
- Operating Temperature: -40°C ~ 105°C (same thermal range)
- Insulation Material: Liquid Crystal Polymer (LCP) (same material)
- Contact Material: Phosphor Bronze (same base material)
- RoHS Status: ROHS3 Compliant (same compliance level)
Differing Parameters:
- Number of Positions: 21 (main part) vs. 22 (substitute)
- Number of Rows: 1 (main part) vs. 2 (substitute)
- Product Status: Obsolete (main part) vs. Active (substitute)
The M22-7141142 provides an active alternative within the M22 series with enhanced position capacity and dual-row configuration while maintaining electrical and mechanical compatibility parameters.

Engineering Selection Recommendations
The M22-7141142 is the manufacturer-recommended substitute for the obsolete M22-7132142. Both components maintain identical electrical ratings (2A current, 500VAC voltage), thermal operating range (-40°C to 105°C), and mechanical interface specifications (0.079" pitch, through-hole solder termination, push-pull fastening).
The primary design difference is the position and row configuration: the M22-7141142 provides 22 positions arranged in 2 rows compared to the 21 positions in a single row of the original part. This configuration change does not affect electrical or thermal performance but requires PCB layout modification to accommodate the dual-row footprint.
Both components are ROHS3 compliant and utilize identical contact materials (phosphor bronze with gold plating) and insulation materials (liquid crystal polymer). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can the M22-7141142 directly replace the M22-7132142 without PCB modification?
A: No. While electrical and thermal specifications are identical, the M22-7141142 uses a 2-row configuration with 22 positions versus the 1-row, 21-position layout of the M22-7132142. PCB footprint redesign is required.
Q: Are the mating contacts electrically compatible?
A: Yes. Both connectors use identical contact materials (phosphor bronze), contact finish (gold plating), pitch spacing (0.079"), and current/voltage ratings (2A, 500VAC).
Q: What is the significance of the product status difference?
A: The M22-7132142 is obsolete and no longer manufactured. The M22-7141142 is in active production, providing assured availability for new designs and ongoing system support.
Q: Do both connectors meet the same compliance standards?
A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical material flammability ratings (UL94 V-0).
Q: What packaging is available for the substitute part?
A: The M22-7141142 is supplied in tube packaging.
