Equivalent & Substitute Parts Reference for Eaton - Bussmann F520DDST-GY Terminal Block

Part Overview

The Eaton - Bussmann Electrical Division F520DDST-GY is an obsolete terminal block connector. This component is a 4-position, 2-level, gray, disconnect, feed-through terminal block designed for wire ranges 10-22 AWG (0.5-4mm²). It features a fuse/lever disconnect type, screw termination, and polyamide (PA66) insulation. Due to its obsolete status, sourcing alternative models is necessary to maintain production continuity and ensure availability for applications requiring these specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Eaton - Bussmann F520DDST-GY is determined strictly by the following parameters: type (disconnect, feed-through), disconnect type (fuse, lever), number of positions and levels, terminal width, termination style, voltage ratings (IEC/UL), wire gauge range, color, fuse type, insulation material, stripping length, and MSL. Only parts that match these core criteria in the Terminal Blocks product category are included as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The F520DDST-GY is obsolete. The substitute ATDF4 is listed as active with comparable specifications and RoHS compliance. Both maintain a Moisture Sensitivity Level of 1 (Unlimited). Use the substitute only where voltage ratings and fuse size variations are compatible with application requirements as listed in the provided data.
