Is there a pin-compatible replacement for TPSB107K006R0250?

No direct pin-compatible replacement with identical capacitance and ESR was found. TAJB686K010RNJ shares the 1210 package but has lower capacitance (68µF) and higher ESR, making it a high-risk substitution that requires circuit validation.

What risks should I check before replacing TPSB107K006R0250?

Key risks include package mismatch requiring PCB redesign, lower capacitance affecting circuit stability, and higher ESR (Equivalent Series Resistance) impacting performance, especially in power supply filtering applications. Always verify the candidate's datasheet.

TPSB107K006R0250 Alternatives, Datasheet & Cross Reference | AVX

Finding a substitute for the AVX TPSB107K006R0250, a 100µF 6.3V 1210 tantalum capacitor, requires careful review of package size and electrical parameters. While no direct drop-in replacements were found, several functional alternatives exist.

AI replacement insight

Package riskhigh

Most alternatives require a PCB redesign due to different package sizes.

Electrical riskhigh

Candidates may have lower capacitance or higher ESR, impacting circuit performance.

Can it be replaced directly?

There are no direct, risk-free replacements for the TPSB107K006R0250. All candidates have significant differences in package, capacitance, or ESR.

Best replacement path

If a board redesign is possible, TAJE107K025RNJ is a strong functional alternative. If the footprint must be maintained, TAJB686K010RNJ is form-fit but electrically weaker and requires careful analysis.

Main risk

The primary risk is package incompatibility, as most alternatives are in different footprints. For the same-package option, the risk shifts to electrical underperformance due to lower capacitance and higher ESR.

Recommended alternatives

Strong functional alternate if redesign is possible; matches key electricals in a larger 2917 package.
