Is there a pin-compatible replacement for CSTLS4M00G53-B0?

No, a direct pin-compatible (through-hole) replacement for the CSTLS4M00G53-B0 was not identified in this review. All suitable alternatives found are in surface-mount (SMD) packages.

What risks should I check before replacing CSTLS4M00G53-B0?

The main risk is the mechanical form factor. Any replacement requires changing your PCB layout from a through-hole design to a surface-mount design. Electrically, the suggested alternatives are a very close match.

Finding a replacement for the CSTLS4M00G53-B0, a 4MHz through-hole ceramic resonator, involves considering modern surface-mount alternatives. While no direct drop-in parts exist, several functional matches are available.

AI replacement insight

Package riskhigh

Candidate is SMD, target is Through-Hole. Requires board redesign.

Electrical risklow

Key parameters like frequency, tolerance, and capacitance match.

Sourcing risklow

Candidates are from the same manufacturer and are active parts.

Can it be replaced directly?

No direct pin-for-pin replacements for CSTLS4M00G53-B0 were found. The best options are functional alternatives in a different (SMD) package.

Best replacement path

Migrate to an SMD equivalent like CSTCR4M00G53-R0, which requires a PCB layout update but matches all key electrical specifications.

Main risk

The primary risk is the package mismatch (Through-Hole vs. SMD), which makes these parts not drop-in compatible and requires a board redesign.

Recommended alternatives

A functional match with the same frequency and tolerance, but in an SMD package requiring a layout change.
