• Tolerance: ±10% (identical)
• Type: Conformal Coated (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Physical Dimensions: 0.177" Dia (4.50 mm), Height 0.335" (8.50 mm), Lead Spacing 0.125" (3.18 mm) (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters (Upgrade Characteristics):

• Voltage - Rated: 20 V (main part) vs. 25 V (substitute)
• ESR: 7 Ohm (main part) vs. 6 Ohm (substitute)

The TAP225K025GSB represents an electrical upgrade with higher voltage rating and lower ESR, maintaining full mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TAP225K020GSB and TAP225K025GSB maintain Active product status with ROHS3 compliance and identical thermal operating ranges. The TAP225K025GSB provides enhanced circuit protection through its 25 V rated voltage, suitable for applications where supply voltage margins or transient overvoltage conditions exceed the 20 V specification. The reduced ESR of the substitute part (6 Ohm vs. 7 Ohm) offers improved high-frequency performance characteristics. Both components are manufactured by KYOCERA AVX with identical physical footprints, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025GSB replace TAP225K020GSB in all applications?

A: Yes, provided the circuit design does not depend on the specific 20 V voltage rating as a functional limit. The 25 V rated substitute operates safely in circuits designed for 20 V operation.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical radial package dimensions: 0.177" diameter (4.50 mm), maximum seated height of 0.335" (8.50 mm), and lead spacing of 0.125" (3.18 mm). No PCB layout modifications are required.

Q: What is the significance of the ESR difference?

A: The TAP225K025GSB has lower ESR (6 Ohm vs. 7 Ohm), resulting in reduced impedance at high frequencies and lower heat dissipation during ripple current operation.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP225K020GSB and TAP225K025GSB are ROHS3 compliant.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C with 1000 hours lifetime rating at 85°C.
