Substitute Part Grouping Explanation

Substitution eligibility for the M20-1071700 is determined by the following critical parameters:

Primary Compatibility Criteria:

Number of Positions: 34
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

Secondary Compatibility Criteria:

Color: Black
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Two substitute parts are identified:

M20-1071200 (MFR Recommended): Differs in position count (24 vs. 34), making it functionally incompatible for direct substitution in applications requiring 34-position connectivity. This part shares the same manufacturer, series, pitch, row configuration, and termination method but cannot replace the main part in circuits designed for 34 positions.

0022552343 (Parametric Equivalent): Matches all primary compatibility criteria including 34-position count, 2.54mm pitch, dual-row configuration, receptacle type, female socket contacts, and crimp termination. This Molex part from the SL 70450 series provides direct functional equivalence with identical mechanical and electrical interface specifications.

Engineering Selection Recommendations

For Direct Functional Replacement:

The 0022552343 (Molex SL 70450 series) is the appropriate selection for applications requiring direct substitution of the M20-1071700. This part maintains identical position count, pitch, row configuration, and termination specifications. Both parts are ROHS3 compliant with MSL rating of 1. The Molex equivalent operates across an extended temperature range (-40°C to 105°C) compared to the original part (-25°C to 85°C), providing enhanced thermal performance for demanding environments.

Regarding M20-1071200:

The M20-1071200 is not suitable as a direct replacement due to its 24-position configuration versus the 34-position requirement of the original part. This part should only be considered for applications where the circuit design can accommodate reduced position count.

Compliance and Availability:

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory compatibility. The 0022552343 is currently in active production with 1041 units in stock, providing supply continuity for the obsolete M20-1071700.

Frequently Asked Questions (FAQ)

Q: Can the M20-1071200 replace the M20-1071700 in my application?

A: No. The M20-1071200 has 24 positions while the M20-1071700 has 34 positions. Direct substitution is only possible if your circuit design can function with reduced pin count. For applications requiring 34-position connectivity, use the 0022552343.

Q: What is the key difference between the M20-1071700 and 0022552343?

A: Both parts are 34-position receptacles with 2.54mm pitch and dual-row configuration. The primary differences are manufacturer (Harwin vs. Molex), insulation material composition, and operating temperature range. The 0022552343 operates from -40°C to 105°C versus -25°C to 85°C for the original part.

Q: Are the insulation materials interchangeable?

A: The M20-1071700 uses Polyphenylene Ether (PPE) and Polystyrene (PS), while the 0022552343 uses Polyester with glass filler. Both materials are suitable for the specified electrical and mechanical requirements. Material selection should be verified against specific application environmental conditions.

Q: Is the 0022552343 RoHS compliant?

A: Yes. The 0022552343 is ROHS3 compliant with MSL rating of 1 (unlimited), matching the compliance profile of the original M20-1071700.

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

A: The M20-1071700 is obsolete. The M20-1071200 has 1529 units in stock, and the 0022552343 has 1041 units in stock, both in active production status.

Q: Do these housings include contacts?

A: No. All three parts are housings only. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.
