Substitute Part Grouping Explanation

Substitution of the Weidmüller 1972640000 is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: 6-position plug with female sockets
• Pitch Specification: 0.150" (3.81mm) center-to-center spacing
• Mounting & Orientation: Free-hanging in-line with 180° wire entry
• Electrical Ratings: IEC 17.5A/320V and UL 10A/300V performance
• Termination Method: Screwless push-in spring mechanism
• Wire Compatibility: Support for 16-26 AWG (0.14-1.5mm²)
• Environmental & Compliance: UL94 V-0 flammability, IP20 ingress protection, RoHS compliance

The substitute part Weidmüller 2442640000 maintains full equivalence across all critical electrical, mechanical, and environmental parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 2442640000 is the direct active equivalent for the obsolete 1972640000. Both components maintain identical electrical performance under IEC and UL standards, identical mechanical configuration with 6-position 0.150" pitch, and equivalent environmental compliance including UL94 V-0 flammability rating and RoHS compliance.

The substitute part offers the following advantages:

• Active Product Status: Currently manufactured and supported by Weidmüller with established supply chain availability
• Enhanced Housing Material: PA66 (Nylon 6/6) formulation provides improved chemical and thermal stability compared to standard PA
• Operational Temperature Range: The substitute operates to -50°C ~ 100°C, which covers the majority of industrial applications; applications requiring operation above 100°C should retain the original part specification
• Compliance Continuity: Maintains all regulatory certifications and environmental compliance requirements

For applications operating within the -50°C to 100°C range with standard electrical loads up to 17.5A IEC / 10A UL, the 2442640000 provides full functional and electrical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 2442640000 be used as a direct replacement for the 1972640000 in existing assemblies?

A: Yes, for applications operating within -50°C to 100°C. Both parts share identical pitch (0.150"), position count (6), electrical ratings (17.5A IEC / 10A UL), termination method (push-in spring), and mounting configuration (free-hanging in-line 180°). The housing material difference (PA66 vs. PA) does not affect mechanical or electrical compatibility.

Q: What is the difference in operating temperature range between these parts?

A: The 1972640000 operates to 120°C maximum, while the 2442640000 operates to 100°C maximum. Applications requiring sustained operation above 100°C should specify the original part. For standard industrial temperature ranges (-50°C to 85°C), both parts are equivalent.

Q: Are there any packaging or inventory considerations?

A: The 1972640000 is obsolete with limited remaining inventory (904 pcs). The 2442640000 is active production with current availability (990 pcs). For new designs and ongoing procurement, the 2442640000 is the recommended selection.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 1972640000 and 2442640000 accept wire gauges from 16-26 AWG (0.14-1.5mm²) with identical 9mm wire strip length and push-in spring termination.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS compliance, UL94 V-0 flammability rating, IP20 ingress protection, and EAR99 export classification. Regulatory requirements are fully satisfied by either part.
