The 1.5KE7.5CA-E3/51: The 1.5KE7.5CA-/51 is flagged Last Buy by Vishay — the manufacturer's last-time-buy window is closing. For a production BOM that still specifies this order code, the procurement decision is whether to secure final inventory or qualify a replacement before the line-item goes EOL.
The TransZorb series includes many 1.5KE voltage variants, but a direct pin-compatible drop-in with the same 6.4 V standoff and bidirectional configuration is not listed as a replacement. Sourcing through independent channels is the practical path for existing BOM lines.
