A50422007 Equivalent & Substitute Parts Reference

Part Overview

The A50422007 is a 20-circuit barrier block connector manufactured by Eaton - Electronics Division, designed for applications requiring screw-terminated connections with a 0.250" (6.35mm) pitch. This component features a dual-wall barrier configuration, captive plate screws for top termination, and wire wrap capability for bottom termination.

The A50422007 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for maintenance, repair, and new design implementations where this connector type is specified.

Substitute Part Grouping Explanation

Substitute parts for the A50422007 are identified based on matching the following critical electrical and mechanical parameters:

• Terminal Block Type: Barrier Block configuration
• Circuit Count: 20 circuits
• Pitch Specification: 0.250" (6.35mm) center-to-center spacing
• Current Rating: 10A minimum
• Voltage Rating: 300V minimum
• Top Termination Method: Screw-based with captive plate
• Barrier Configuration: Dual-wall (2 Wall) barrier type
• Insulation Material: Thermoplastic with UL94 V-0 flammability rating

The substitute part YK2112003000G meets these core electrical and mechanical compatibility criteria. Variations in wire gauge range, bottom termination method, mounting type, and operating temperature upper limit do not preclude substitution when the primary electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: YK2112003000G

The YK2112003000G is an active-status substitute for the obsolete A50422007. Both components share identical electrical ratings (10A, 300V), circuit count (20), pitch (0.250"), termination method (screw with captive plate), and barrier configuration (dual-wall).

Compliance Considerations:

The YK2112003000G carries ROHS3 compliance status, whereas the A50422007 is non-compliant. For applications subject to RoHS regulatory requirements, the YK2112003000G satisfies current environmental compliance mandates. The A50422007 remains suitable for legacy systems and applications where RoHS compliance is not mandated.

Operational Differences:

The YK2112003000G supports an extended operating temperature range (-40°C to 115°C) compared to the A50422007 (-40°C to 105°C), providing additional thermal margin in high-temperature environments.

Wire gauge compatibility differs: the A50422007 accepts 18-30 AWG, while the YK2112003000G accepts 16-22 AWG. Applications using wire gauges outside the 16-22 AWG range require verification against the YK2112003000G specifications.

Bottom termination differs: the A50422007 uses wire wrap, while the YK2112003000G uses PC pins. This difference affects PCB integration and mounting methodology and must be evaluated against circuit board design requirements.

Frequently Asked Questions (FAQ)

Q: Can the YK2112003000G directly replace the A50422007 in existing assemblies?

A: The YK2112003000G matches the A50422007 in electrical ratings, circuit count, pitch, and screw termination method. However, the bottom termination differs (PC pin versus wire wrap). Direct mechanical replacement requires verification that the PCB or mounting substrate accommodates PC pin termination. Top-side screw termination is identical and compatible.

Q: What wire gauge range should be used with the YK2112003000G?

A: The YK2112003000G accepts 16-22 AWG wire. If the original design specifies 18-30 AWG, wire gauges 23-30 AWG are outside the YK2112003000G specification and require alternative solutions.

Q: Does the YK2112003000G meet RoHS requirements?

A: Yes. The YK2112003000G carries ROHS3 compliance status. The original A50422007 is RoHS non-compliant. For applications requiring RoHS compliance, the YK2112003000G satisfies current environmental regulations.

Q: Are the electrical ratings identical between the two parts?

A: Yes. Both components are rated for 10A current and 300V voltage with identical 0.250" pitch and dual-wall barrier configuration. Electrical interface compatibility is confirmed.

Q: What is the difference in operating temperature range?

A: The A50422007 operates from -40°C to 105°C. The YK2112003000G operates from -40°C to 115°C. The YK2112003000G provides 10°C additional upper temperature margin. For applications operating below 105°C, both parts are equivalent in this parameter.

Q: Can I use the YK2112003000G in new designs?

A: Yes. The YK2112003000G is active-status and available in production quantities. It is suitable for new designs requiring a 20-circuit, 0.250" pitch barrier block connector with screw termination and dual-wall barrier configuration.
