Parameter Comparison

Engineering Selection Recommendations

Both TAP225M020GSB and TAP225K025GSB maintain Active product status with full ROHS3 compliance and REACH unaffected classification. The TAP225K025GSB provides superior electrical characteristics through improved tolerance (±10% versus ±20%) and reduced ESR (6 Ohm versus 7 Ohm), while maintaining identical mechanical compatibility and thermal operating range. The higher voltage rating (25 V versus 20 V) offers additional design margin without compromising form factor or lead spacing. Selection between these parts depends on application voltage requirements and tolerance specifications rather than physical or thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025GSB replace TAP225M020GSB in existing designs? A: Yes. The substitute maintains identical physical dimensions, lead spacing, mounting type, and operating temperature range. No PCB layout modifications are required.

Q: What are the key differences between these parts? A: The primary differences are voltage rating (25 V versus 20 V), tolerance (±10% versus ±20%), and ESR (6 Ohm versus 6 Ohm). The substitute offers improved electrical performance.

Q: Are there any compliance or certification differences? A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN and HTSUS codes.

Q: Does the higher voltage rating affect circuit behavior? A: No. A higher voltage-rated capacitor operates safely at lower voltages. The 25 V rating provides additional design margin without altering capacitance or ESR characteristics at the application voltage.

Q: Are the conformal coating specifications identical? A: Yes. Both parts are conformal coated tantalum capacitors with identical coating type and thermal performance specifications.
