Cinch Connectivity Solutions 2-141 Equivalent & Substitute Parts

Part Overview

The Cinch Connectivity Solutions 2-141 is a 2-circuit barrier block connector with 0.438" (11.12mm) pitch, designed for screw-based termination in chassis and panel mounting applications. This component operates at 20A current rating and 250V voltage rating, with phenolic insulation material and dual-wall barrier configuration. The part is active in production status and RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align within acceptable tolerances for the barrier block terminal category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-141 barrier block connector is determined by the following critical parameters:

• Circuit Configuration: 2-circuit requirement with 4 wire entries
• Pitch Tolerance: 0.438" (11.12mm) nominal, with 0.437" (11.10mm) acceptable within mechanical tolerance
• Termination Method: Screw-based top termination with closed bottom configuration
• Barrier Architecture: Dual-wall (2 Wall) barrier type for electrical isolation
• Mounting Interface: Chassis and panel mounting capability
• Electrical Ratings: Minimum 20A current capacity and 250V voltage rating
• Wire Compatibility: Support for 14 AWG wire gauge or broader range

The TE Connectivity AMP Connectors part 1546671-2 qualifies as a substitute based on matching circuit count, pitch specification within tolerance, screw termination, dual-wall barrier configuration, and mounting type. Enhanced electrical ratings (25A, 300V) and expanded wire gauge range (14-22 AWG) provide operational margin.

Parameter Comparison

Engineering Selection Recommendations

Both the 2-141 and 1546671-2 maintain active product status and meet regulatory compliance requirements. The 2-141 carries RoHS Compliant certification, while the 1546671-2 carries ROHS3 Compliant certification, indicating alignment with current environmental standards. Both components share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications for export and tariff purposes.

The 1546671-2 substitute provides enhanced electrical performance margins with 25A current rating versus 20A, and 300V voltage rating versus 250V. The expanded wire gauge acceptance (14-22 AWG versus 14 AWG) offers greater application flexibility. Pitch tolerance between 0.438" and 0.437" falls within standard mechanical manufacturing tolerances for barrier block connectors.

Selection between these parts should be based on application-specific electrical requirements, existing inventory considerations, and mechanical fit verification within the target assembly.

Frequently Asked Questions (FAQ)

Q: What determines if a barrier block connector can substitute for the 2-141?

A: Substitution eligibility requires matching circuit count (2), compatible pitch specification (0.438" ±0.001"), screw-based termination, dual-wall barrier configuration, and electrical ratings meeting or exceeding 20A and 250V. Mounting type must support both chassis and panel installation.

Q: Is the pitch difference between 0.438" and 0.437" acceptable?

A: Yes. The 0.001" difference falls within standard mechanical tolerance for barrier block terminal spacing and does not affect mechanical or electrical compatibility in typical applications.

Q: Can the 1546671-2 handle the same wire gauges as the 2-141?

A: The 1546671-2 accepts 14-22 AWG wire, which includes the 14 AWG specification of the 2-141. The expanded range provides compatibility with additional wire sizes.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances directives. ROHS3 represents the current version of the standard. Both parts meet environmental compliance requirements.

Q: Are there any material differences between the two connectors?

A: The 2-141 uses phenolic insulation material, while the 1546671-2 uses thermoplastic insulation. Both materials are suitable for barrier block applications. The 1546671-2 carries UL94 V-0 flammability rating, indicating superior flame resistance.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Mechanical fit must be verified due to pitch tolerance and potential differences in flange dimensions. Electrical compatibility is confirmed based on parameter alignment. Physical installation testing is recommended before production deployment.
