Substitute Part Grouping Explanation

Substitution of the TAP155M025CCSY is permissible with the TAP155K035CCS based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 1.5 µF (identical)
• Type: Conformal Coated (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Size / Dimension: 0.177" Dia (4.50 mm) (identical)
• Height - Seated (Max): 0.335" (8.50 mm) (identical)
• Lead Spacing: 0.197" (5.00 mm) (identical)
• Operating Temperature: -55°C ~ 125°C (identical)
• Lifetime @ Temp.: 1000 Hrs @ 85°C (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameters (Upgrade Characteristics):

• Voltage - Rated: 25 V (original) vs. 35 V (substitute) — higher voltage rating provides increased safety margin
• Tolerance: ±20% (original) vs. ±10% (substitute) — tighter tolerance specification
• ESR: 8 Ohm (original) vs. 6 Ohm (substitute) — lower equivalent series resistance

The TAP155K035CCS functions as an electrical upgrade while maintaining identical mechanical and thermal characteristics, allowing direct board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

The TAP155K035CCS qualifies as a direct substitute for the TAP155M025CCSY in applications where the original 25 V rating is specified. Both components maintain Active product status from KYOCERA AVX and satisfy ROHS3 compliance requirements. The substitute part provides enhanced electrical performance through a higher voltage rating (35 V vs. 25 V) and improved tolerance specification (±10% vs. ±20%), while maintaining identical mechanical footprint, thermal operating range, and conformal coating protection. The reduced ESR of the substitute part (6 Ohm vs. 8 Ohm) offers lower impedance characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications; the substitute is suitable for designs requiring improved performance margins or tighter capacitance accuracy.

Frequently Asked Questions (FAQ)

Q: Can TAP155K035CCS replace TAP155M025CCSY in existing designs? A: Yes. Both parts share identical capacitance (1.5 µF), mechanical dimensions, lead spacing, and thermal characteristics. The substitute operates at a higher voltage rating and lower ESR, making it electrically compatible for direct board-level substitution.

Q: What are the key differences between these two parts? A: The primary differences are voltage rating (25 V vs. 35 V), tolerance specification (±20% vs. ±10%), and ESR (8 Ohm vs. 6 Ohm). All other electrical and mechanical parameters remain identical.

Q: Does the higher voltage rating of TAP155K035CCS affect circuit operation? A: No. A component rated for higher voltage than required operates safely at lower voltages. The 35 V rating of the substitute provides additional safety margin when used in 25 V circuits.

Q: Are the physical packages identical? A: Yes. Both parts are radial through-hole components with identical diameter (0.177" / 4.50 mm), height (0.335" / 8.50 mm), and lead spacing (0.197" / 5.00 mm). They occupy the same board footprint.

Q: Do both parts meet the same compliance standards? A: Yes. Both TAP155M025CCSY and TAP155K035CCS are ROHS3 compliant and maintain identical operating temperature ranges (-55°C ~ 125°C) and lifetime specifications (1000 Hrs @ 85°C).

Q: Which part should be selected for new designs? A: Selection depends on circuit voltage requirements. For 25 V applications, either part is suitable; the TAP155K035CCS offers improved performance margins. For designs requiring the lowest cost at specified voltage, the TAP155M025CCSY is appropriate.
