Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1741660000 is determined by strict equivalence across the following critical parameters:

• Mechanical Compatibility: Number of positions (4), pitch (0.200" / 5.08mm), plug wire entry angle (225°), and mounting type (free hanging in-line) must remain identical
• Electrical Ratings: Current and voltage ratings must meet or exceed the original specifications for both IEC and UL standards
• Termination Method: Screw-clamping yoke termination style must be maintained
• Wire Gauge Acceptance: The substitute must accommodate the wire gauge range of the original part
• Material and Safety: Housing material (PBT), contact material (copper alloy), and flammability rating (UL94 V-0) establish baseline compatibility
• Environmental Specifications: Operating temperature range and contact mating finish must be equivalent or superior

The Weidmüller 1946270000 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1946270000 is the direct substitute for the obsolete 1741660000 terminal block plug. Selection is based on the following engineering criteria:

Product Status: The 1946270000 is classified as active product status, ensuring continued availability and manufacturing support. The original 1741660000 is obsolete and no longer in production.

Electrical Performance: The substitute meets or exceeds all electrical specifications. IEC current rating increases from 16.5A to 17.5A, and UL current rating increases from 10A to 15A. Voltage ratings remain equivalent at 400V (IEC) and 300V (UL).

Mechanical Compatibility: All critical mechanical parameters are identical, including 4-position configuration, 0.200" (5.08mm) pitch, 225° wire entry angle, and free-hanging in-line mounting. Screw-clamping yoke termination is maintained with identical M2.5 screw specifications and torque requirements.

Wire Gauge Acceptance: The substitute accommodates a wider wire gauge range (12-30 AWG / 0.2-4mm²) compared to the original (12-26 AWG / 0.2-2.5mm²), providing greater flexibility for field applications.

Compliance and Safety: Both parts maintain identical material specifications (PBT housing, copper alloy contacts), UL94 V-0 flammability rating, and environmental certifications (REACH Unaffected, EAR99 ECCN classification).

Regulatory Alignment: The substitute includes RoHS compliance and improved moisture sensitivity level (MSL 1 - Unlimited) compared to the original, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1946270000 be used as a direct replacement for the 1741660000 in existing installations?

A: Yes. The 1946270000 is mechanically and electrically compatible with the 1741660000. All critical parameters—position count, pitch, wire entry angle, mounting type, and termination method—are identical. The substitute meets or exceeds the electrical ratings of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1946270000 is active; 1741660000 is obsolete), wire gauge acceptance range (1946270000 accepts 12-30 AWG versus 12-26 AWG), electrical current ratings (1946270000 rated 17.5A IEC / 15A UL versus 16.5A IEC / 10A UL), and regulatory compliance (1946270000 includes RoHS compliance and improved MSL rating).

Q: Are there any packaging differences between these parts?

A: The 1741660000 is supplied with unspecified packaging, while the 1946270000 is supplied in bulk packaging. This difference does not affect electrical or mechanical compatibility.

Q: What wire gauges are compatible with the 1946270000?

A: The 1946270000 accepts wire gauges from 12-30 AWG (0.2-4mm²), which encompasses the original part's range of 12-26 AWG (0.2-2.5mm²).

Q: Are the screw torque specifications the same for both parts?

A: Yes. Both the 1741660000 and 1946270000 use M2.5 screws with identical torque specifications of 0.4-0.5 Nm (4.6-4.4 Lb-In).

Q: Does the 1946270000 have any additional certifications or compliance features?

A: The 1946270000 includes RoHS compliance and an improved moisture sensitivity level (MSL 1 - Unlimited) compared to the original part. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Q: What is the operating temperature range for the substitute part?

A: The 1946270000 operates across the same temperature range as the original: -50°C to 100°C.
