Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 796921-4 is based on electrical and mechanical parameter equivalence within the TSB230 Buchanan series. The substitute part 1776295-4 maintains identical specifications across all critical functional parameters: 4-circuit configuration, 0.315" pitch, 30A current rating, 250V voltage rating, 12-26 AWG wire gauge compatibility, screw termination, and UL94 V-0 flammability rating.

The substitution is valid based on the following key parameters:

  • Identical terminal block type (Eurostyle Terminal Strip)
  • Matching circuit count and wire entry configuration
  • Equivalent pitch spacing and mechanical footprint
  • Identical electrical ratings (current, voltage, wire gauge)
  • Matching termination method and barrier type
  • Equivalent insulation material and flammability certification

The primary distinction between the main part and substitute is product status: 796921-4 is obsolete, while 1776295-4 is active and currently manufactured. The substitute also includes enhanced environmental specifications (extended operating temperature range of -35°C to 150°C versus 150°C maximum) and RoHS compliance certification.
