MCT-1 Equivalent & Substitute Parts

Part Overview

The MCT-1 is a 1-circuit barrier block connector manufactured by Curtis Industries, designed for chassis and panel mounting applications. This terminal block features screws with captive plate termination, dual-wall barrier construction, and supports wire gauges from 14-22 AWG with a 15A current rating. The product is Active status and fully compliant with RoHS3 and REACH regulations. Substitute parts may be required due to inventory constraints, application-specific mounting requirements, or termination method preferences.

Key Parameters

Substitute Part Grouping Explanation

The MCT-1 substitute relationship is based on the following critical parameters:

Wire gauge compatibility (14-22 AWG for MCT-1; 14-16 AWG for substitute 8284) provides overlap in the 14-16 AWG range, enabling functional substitution for applications within this shared range. Current rating (15A) and termination method (screws with captive plate vs. crimp) represent the primary functional differences. The substitute part 8284 is a quick-connect crimp terminal manufactured by Keystone Electronics, suitable for applications where crimp termination is acceptable and wire gauge requirements do not exceed 16 AWG. Both parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Selection between MCT-1 and substitute 8284 depends on application-specific requirements:

The MCT-1 is specified for barrier block applications requiring screw termination with captive plate assembly, dual-wall barrier construction, and chassis or panel mounting. This configuration is suitable for fixed installations where tool-based termination and secure mechanical connection are required.

The 8284 substitute is applicable only when crimp termination is acceptable and wire gauge requirements remain within the 14-16 AWG overlap range. This part is designed for free-hanging, in-line applications and does not provide the same barrier block structure or mounting flexibility as the MCT-1.

Both parts maintain Active product status and full RoHS3 compliance, ensuring regulatory equivalence. Selection should be based on termination method compatibility and mounting configuration requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the 8284 directly replace the MCT-1 in all applications?

A: No. The 8284 is a crimp terminal designed for free-hanging, in-line mounting, while the MCT-1 is a barrier block connector for chassis and panel mounting. Substitution is valid only when the application accepts crimp termination and does not require barrier block construction or fixed mounting.

Q: What wire gauges are compatible between MCT-1 and 8284?

A: Both parts support 14-16 AWG wire. The MCT-1 extends to 22 AWG, but the 8284 is limited to 16 AWG maximum. Substitution is restricted to the 14-16 AWG overlap range.

Q: Are there compliance differences between MCT-1 and 8284?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings. Regulatory compliance is equivalent.

Q: What is the primary functional difference between these parts?

A: The MCT-1 uses screw termination with captive plate assembly and provides dual-wall barrier construction for fixed mounting applications. The 8284 uses crimp termination and is designed for in-line, free-hanging configurations. These represent different connector architectures suited to different application types.

Q: Should current rating be a factor in substitution decisions?

A: Yes. The MCT-1 specifies 15A current rating. The 8284 does not provide a current rating specification. Applications requiring confirmed 15A capacity should use the MCT-1 or verify the 8284's current handling capability through the manufacturer.
