M20-1071500 Equivalent & Substitute Parts

Part Overview

The M20-1071500 is a 30-position rectangular connector receptacle housing manufactured by Harwin Inc., designed for 0.100" (2.54mm) pitch applications. This component features a 2-row configuration with crimp-style female socket contacts and operates across the -25°C to 85°C temperature range. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution eligibility for the M20-1071500 is determined by strict alignment with the following critical parameters:

Number of Positions: 30
Pitch: 0.100" (2.54mm)
Number of Rows: 2
Row Spacing: 0.100" (2.54mm)
Connector Type: Receptacle
Contact Type: Female Socket
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Color: Black

Two substitute parts are identified:

M20-1071200 (MFR Recommended): Harwin Inc. active part with 24 positions. This part shares the same pitch, row configuration, mounting type, and termination method but differs in position count. Substitution requires design modification to accommodate reduced contact capacity.

0022552301 (Parametric Equivalent): Molex SL 70450 series part with 30 positions. This part matches all critical position, pitch, row, and mounting parameters. It provides direct functional equivalence with identical contact count and mechanical interface specifications.

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 0022552301 (Molex) is the parametric equivalent, matching all critical mechanical and electrical specifications including the 30-position count. Both parts are ROHS3 compliant with MSL 1 rating. The Molex part offers an extended operating temperature range (-40°C to 105°C) compared to the original specification (-25°C to 85°C), providing additional thermal margin. This part is currently active in production with established supply availability.

For Design Modification: The M20-1071200 (Harwin Inc.) remains within the same manufacturer family and maintains all interface parameters except position count. This option is suitable only when circuit design can accommodate a 24-position configuration. The part is active and available from the original manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the M20-1071200 (24-position) directly replace the M20-1071500 (30-position)?

A: No. While both parts share identical pitch, row spacing, and mounting characteristics, the 24-position housing cannot accommodate 30 contacts. Direct substitution requires circuit redesign to eliminate 6 signal connections or implement alternative routing.

Q: Is the 0022552301 (Molex) mechanically compatible with the M20-1071500 connector system?

A: Yes. The 0022552301 matches all critical mechanical parameters: 30 positions, 0.100" pitch, 2-row configuration, 0.100" row spacing, and free-hanging in-line mounting. Crimp termination is identical, ensuring compatibility with existing contact and cable assembly processes.

Q: What is the significance of the extended operating temperature range in the Molex part?

A: The 0022552301 operates from -40°C to 105°C, compared to the original -25°C to 85°C specification. This extended range provides additional thermal margin for applications subject to wider environmental extremes but does not alter electrical or mechanical compatibility for standard operating conditions.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the M20-1071200 and 0022552301 are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the compliance profile of the original M20-1071500.

Q: What is the current availability status of these substitutes?

A: The M20-1071200 (Harwin) and 0022552301 (Molex) are both active production parts with established inventory levels, ensuring supply continuity for new designs and field service requirements.
