Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1940640000 is determined by strict equivalence across the following critical parameters:

• Number of positions: 13
• Pitch spacing: 0.150" (3.81mm)
• Connector type: Plug with female sockets
• Termination method: Screw-clamping yoke
• Mounting configuration: Free hanging (in-line)
• Wire entry angle: 270°
• Current and voltage ratings: 17.5A (IEC) / 320V (IEC)
• Wire gauge compatibility: 16-28 AWG (0.2-1.5mm²)
• Operating temperature range: -50°C to 120°C
• Flammability and compliance certifications: UL94 V-0, RoHS compliant

The substitute part 1940570000 maintains full electrical and mechanical compatibility across all these parameters. Variations in housing color and product status do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The 1940570000 is a direct functional equivalent to the 1940640000. Both components are manufactured by Weidmüller within the Omnimate BC series and maintain identical electrical ratings, mechanical specifications, and compliance certifications.

The primary distinction is product status: the 1940640000 is obsolete, while the 1940570000 is active. For new designs and ongoing procurement, the 1940570000 is the appropriate selection. Both parts carry RoHS compliance and REACH unaffected status, meeting current regulatory requirements.

Housing color (green versus orange) and packaging format (unspecified versus bulk) are cosmetic and logistical variations that do not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1940570000 directly replace the 1940640000 in existing installations?

A: Yes. All electrical ratings, mechanical dimensions, termination methods, and mounting configurations are identical. The parts are functionally interchangeable.

Q: Does the color difference between the two parts affect compatibility?

A: No. Housing color is a cosmetic attribute and does not impact electrical performance or mechanical fit.

Q: Why is the 1940640000 listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The 1940570000 remains in active production and is the recommended source for new procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1940640000 and 1940570000 are RoHS compliant and REACH unaffected.

Q: What wire gauges are compatible with these terminal blocks?

A: Both parts accept wire gauges from 16-28 AWG (0.2-1.5mm²).

Q: What is the maximum current and voltage rating?

A: IEC ratings are 17.5A at 320V. UL ratings are 10A at 300V.

Q: Can these parts be used in applications requiring higher temperature operation?

A: Both parts are rated for -50°C to 120°C. Applications requiring operation outside this range require alternative components.

Q: What torque specification applies to the screw terminals?

A: The screw torque specification is 0.2-0.25 Nm (1.7-2.2 Lb-In) for both parts.
