Substitute Part Grouping Explanation

Substitution of the TAP335M025SCS is permissible when the following criteria are met:

• Capacitance value remains 3.3 µF
• Voltage rating is 25 V or higher
• Tolerance specification is equal to or tighter than ±20%
• Type is conformal coated tantalum
• ESR is 5 Ohm or lower
• Mounting type is through-hole radial
• Package dimensions match: 0.177" Dia (4.50 mm), Height 0.295" (7.50 mm), Lead Spacing 0.098" (2.50 mm)
• Operating temperature range encompasses -55°C ~ 125°C
• RoHS3 compliance is maintained

The TAP335K025SCS meets all substitution criteria with an improved tolerance specification of ±10%, providing tighter capacitance accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP335M025SCS and TAP335K025SCS are Active products manufactured by KYOCERA AVX and maintain full ROHS3 compliance. The TAP335K025SCS provides improved tolerance performance at ±10% compared to the ±20% specification of the TAP335M025SCS, while maintaining identical electrical ratings, thermal characteristics, and mechanical form factor. Selection between these parts depends on circuit tolerance requirements and application-specific accuracy specifications.

Frequently Asked Questions (FAQ)

Q: Can TAP335K025SCS replace TAP335M025SCS in existing designs?

A: Yes. The TAP335K025SCS is mechanically and electrically compatible. It occupies the same footprint (0.177" Dia, 0.295" height, 0.098" lead spacing) and maintains identical voltage rating, capacitance value, ESR, and operating temperature range. The tighter ±10% tolerance provides improved accuracy.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. TAP335M025SCS carries ±20% tolerance, while TAP335K025SCS carries ±10% tolerance. All other parameters, including capacitance, voltage, ESR, temperature range, and physical dimensions, are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP335M025SCS and TAP335K025SCS are ROHS3 compliant.

Q: Do these parts have identical thermal characteristics?

A: Yes. Both parts operate across -55°C to 125°C and share the same lifetime specification of 1000 hours at 85°C.

Q: Can I use these parts interchangeably in PCB designs?

A: Yes. Both parts use identical through-hole radial packaging with matching lead spacing and seated height, allowing direct substitution without PCB layout modifications.
