Is there a pin-compatible replacement for MP2103K27B1R5LC?

No direct pin-compatible replacement with the same 7.5mm lead pitch was found in this analysis. All electrically similar candidates have a 10mm lead pitch, requiring board modification.

What risks should I check before replacing MP2103K27B1R5LC?

The main risk is mechanical incompatibility. Verify the lead pitch (7.5mm for target) and physical dimensions (10x4x9mm) against any candidate. Also ensure the replacement is an X2-rated safety capacitor.

Finding a substitute for the SRD MP2103K27B1R5LC, a 10nF 275VAC X2 safety capacitor, requires matching its 7.5mm lead pitch. While functional alternatives exist, they typically have a 10mm pitch and may require board layout changes.

AI replacement insight

Package riskhigh

Lead pitch and dimension mismatch with all viable candidates requires board modification.

Electrical risklow

Candidates match or exceed key electrical ratings like voltage and safety class.

Sourcing risklow

Functional alternatives are available, but require engineering review for mechanical fit.

Can it be replaced directly?

No direct drop-in replacement was identified. All electrically suitable alternatives have a 10mm lead pitch, while the target has a 7.5mm pitch.

Best replacement path

Upgrade to MP1103K44C2R6LC for superior electrical ratings if your PCB layout can accommodate a 10mm lead pitch and larger body.

Main risk

The primary risk is mechanical incompatibility. The 7.5mm lead pitch of the target is not matched by available alternatives, requiring board redesign.

Recommended alternatives

An electrical upgrade with higher voltage and safety ratings, but requires board changes due to a larger size and 10mm lead pitch.
