FFF CompatibilityMatches the 4-lead radial package, 52.5mm lead spacing, and 57.5mm x 35.0mm physical footprint perfectly.Virtually identical body dimensions (only 0.3mm difference in height, which is easily accommodated).Exceeds the original voltage rating (650V vs 630V) and maintains the same 75 µF capacitance with ±5% tolerance.Uses the identical 4-lead 52.5mm pitch configuration, but the body width is 38mm (vs 35mm) which may impact high-density layouts.Body dimensions are slightly larger (57.5mm L x 38.0mm W x 57.5mm H) compared to the original (57.5mm L x 35.0mm W x 50.0mm H).Exceeds the original 630V rating with an 800V DC limit while offering a wider temperature operating window.
AI Summary

B32798G2756J by Panasonic Industry: Panasonic.

This is the premier drop-in replacement, offering an identical footprint, pin configuration, and tighter tolerance specs, along with AEC-Q200 automotive-grade reliability.

  • Identical foot-print and pitch (57.5mm x 35.0mm, 52.5mm lead spacing)
  • Exact match for capacitance (75 µF) and tight ±5% tolerance
  • Higher DC voltage rating (650V DC vs 630V DC)
  • Slightly higher nominal ESR (3.1 mOhms vs 2.1 mOhms)

An active replacement from the original manufacturer (TDK/EPCOS) that offers a much higher voltage margin but in a slightly taller and wider housing.

  • Same manufacturer line (TDK) ensuring similar design philosophy and materials
  • Significantly higher voltage rating (800V DC vs 630V DC)
  • AEC-Q200 qualified with an extended -55°C to 105°C temperature range
  • Wider housing (38.0mm vs 35.0mm) and taller height (57.5mm vs 50.0mm) requiring physical clearance
  • Relaxed tolerance of ±10% compared to the original ±5%

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.

Frequently asked questions

Yes. The Panasonic Industry B32798G2756J is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
