Application Scenarios & Design Considerations

Low Insertion Loss

Alternative Part Number

  • B39871-B2026-B510 --: Surface acoustic wave filter in the same 2026 frequency class with comparable insertion loss and package style, widely available as a drop-in functional substitute.
  • SAWFD1G90CB0F0A --: SAW filter with similar center frequency and bandwidth characteristics, suitable for RF front-end filtering where the SF2026B is used.
  • AFS2026 --: SAW filter from a different series offering comparable electrical performance and a similar footprint, usable as a second-source alternative.
  • SF2026 --: Same SF series SAW filter with nearly identical center frequency and bandwidth; the B suffix is a package or tolerance variant, so the base part is the closest functional match.
  • B39162B2026B310 --: EPCOS SAW filter in the same 2026 frequency band with comparable insertion loss and impedance, suitable as a drop-in replacement after pinout verification.
  • TA2026A --: Tai-Saw SAW filter covering the same 2026 MHz band with similar bandwidth and package style, offering a cost-effective alternative from a different series.
