A480303CW Equivalent & Substitute Parts

Part Overview

The A480303CW is a 3-circuit barrier block connector manufactured by Eaton - Electronics Division, part of the Magnum® A4000 series. This component functions as a chassis or panel-mounted terminal block with screw termination and captive plate design, rated for 50A at 150V with wire gauge compatibility of 8-16 AWG.

The A480303CW is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for applications requiring this connector type. Active alternatives within the same product family provide equivalent electrical and mechanical performance with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the A480303CW is determined by equivalence across the following critical parameters:

• Terminal Block Configuration: Barrier block type with 3 circuits and 0.562" (14.27mm) pitch
• Electrical Ratings: 50A current capacity and 150V voltage rating
• Wire Compatibility: 8-16 AWG wire gauge acceptance
• Termination Method: Screw termination with captive plate on top connection
• Barrier Design: 2 Wall (Dual) barrier construction
• Environmental Specifications: Operating temperature range of -40°C ~ 105°C and UL94 V-0 flammability rating
• Mounting Configuration: Chassis and panel mounting capability

The A400303 meets all these criteria and is classified as an active product within the same Magnum® A4000 series, making it a direct functional equivalent to the obsolete A480303CW.

Parameter Comparison

Engineering Selection Recommendations

The A400303 is the direct substitute for the obsolete A480303CW. Both components share identical electrical ratings, mechanical dimensions, termination methods, and environmental specifications within the Magnum® A4000 series.

The primary distinction between these parts is product status and regulatory compliance. The A480303CW is obsolete and RoHS non-compliant, while the A400303 is an active product with ROHS3 compliance and REACH unaffected status. For new designs or system replacements, the A400303 is the appropriate selection.

Both parts are manufactured by Eaton - Electronics Division and are functionally interchangeable in applications requiring a 3-circuit barrier block connector with 50A/150V ratings and 0.562" pitch spacing. The A400303 is available in bulk packaging with higher inventory levels, supporting production and replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can the A400303 directly replace the A480303CW in existing installations?

A: Yes. The A400303 is electrically and mechanically equivalent to the A480303CW. Both components have identical circuit count, pitch spacing, current and voltage ratings, wire gauge compatibility, termination methods, and operating temperature ranges. Direct substitution is supported without circuit modification.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The A480303CW is RoHS non-compliant, while the A400303 is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the A400303 must be used. For legacy systems without such requirements, both parts remain functionally equivalent.

Q: Are there packaging differences between the A480303CW and A400303?

A: The A480303CW is supplied with unspecified packaging, while the A400303 is supplied in bulk packaging. This distinction affects inventory management and procurement processes but does not impact electrical or mechanical performance.

Q: What determines whether a part can substitute for the A480303CW?

A: Substitution is determined by matching the following parameters: barrier block terminal type, 3-circuit configuration, 0.562" pitch spacing, 50A current rating, 150V voltage rating, 8-16 AWG wire gauge compatibility, screw termination with captive plate, 2 Wall dual barrier design, -40°C to 105°C operating temperature range, and UL94 V-0 flammability rating.

Q: Is the A400303 the only active substitute available?

A: Based on the provided data, the A400303 is the identified substitute for the A480303CW within the Magnum® A4000 series. Both parts are manufactured by Eaton - Electronics Division and meet all functional and electrical requirements for direct replacement.
