Equivalent & Substitute Parts for P20R104K5-F

Part Overview

The Cornell Dubilier Electronics P20R104K5-F is a 0.1 µF ±10% 50V ceramic capacitor with X7R temperature coefficient in axial through-hole configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production support, maintenance, and design continuity. The P20 series axial ceramic capacitor remains functionally relevant for general-purpose applications despite its discontinued status. Direct substitutes with identical electrical specifications and compatible physical dimensions are available from active manufacturers including KEMET, KYOCERA AVX, and Vishay Beyschlag/Draloric/BC Components.

Direct Substitutes maintain identical electrical specifications (0.1 µF, 50V, ±10%, X7R) with compatible physical dimensions and active product status. These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced voltage ratings (100V) or improved tolerance (±5%) while maintaining the same capacitance and temperature coefficient. These parts are backward-compatible and suitable for applications requiring higher safety margins or tighter tolerances.

Physical Dimension Variations among substitute parts reflect different manufacturer design approaches. Axial length ranges from 0.150" to 0.260" (3.80mm to 6.60mm) and diameter from 0.098" to 0.120" (2.50mm to 3.05mm). PCB layout compatibility must be verified for each substitute based on available board space.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select C420C104K5R5TA7200 (KEMET) as the primary direct substitute. This part matches the P20R104K5-F in all critical parameters: 0.1 µF capacitance, 50V voltage rating, ±10% tolerance, X7R temperature coefficient, and identical axial dimensions (0.100" Dia x 0.260" L). The part is active with 20,100 units in stock, ensuring supply continuity. ROHS3 compliance and MSL 1 rating match the original specification.

Alternative direct substitutes with identical electrical specifications include:

SA205C104KAR or SA205C104KARC (KYOCERA AVX) - identical dimensions to P20R104K5-F
C410C104K5R5TA or C410C104K5R5TA7200 (KEMET) - shorter axial length (0.170" vs 0.260")
A104K15X7RF5TAA (Vishay) - compact form factor (0.150" length)

For Voltage Upgrade Applications:

Select A104K20X7RH5TAA (Vishay, 100V) or C410C104K1R5TA (KEMET, 100V) when circuit design permits higher voltage rating. These upgrades provide enhanced safety margin and are backward-compatible with 50V circuit requirements. Both maintain 0.1 µF capacitance and X7R temperature coefficient.

For Tolerance Upgrade Applications:

Select C412C104J5R5TA (KEMET, ±5% tolerance) when tighter capacitance tolerance is required. This part maintains 50V rating and X7R coefficient but features improved tolerance specification. Physical dimensions differ slightly (0.120" Dia vs 0.100" Dia).

Compliance Verification:

All substitute parts are ROHS3 compliant and suitable for applications requiring regulatory adherence. Moisture sensitivity levels are either MSL 1 (unlimited) or Not Applicable, matching or exceeding the original specification.

Frequently Asked Questions (FAQ)

Q: Can A104K15X7RF5TAA replace P20R104K5-F directly on the PCB?

A: A104K15X7RF5TAA is electrically equivalent (0.1 µF, 50V, ±10%, X7R) but has a shorter axial length (0.150" vs 0.260"). Direct PCB substitution is possible only if board layout accommodates the shorter component. Verify available lead spacing and mounting hole positions before assembly.

Q: What is the difference between C410C104K5R5TA and C420C104K5R5TA7200?

A: Both are KEMET AxiMax 400 Comm X7R capacitors with identical electrical specifications (0.1 µF, 50V, ±10%, X7R). The primary difference is axial length: C410C is 0.170" long while C420C is 0.260" long, matching the original P20R104K5-F dimensions. Select C420C for direct dimensional replacement.

Q: Are KYOCERA AVX SA105C104KAR and SA205C104KAR interchangeable?

A: Both parts are electrically identical (0.1 µF, 50V, ±10%, X7R) and ROHS3 compliant. SA105C is 0.170" long (compact) while SA205C is 0.260" long (standard). They are interchangeable electrically but differ in physical dimensions. PCB layout determines which is suitable.

Q: Can I use A104K20X7RH5TAA (100V) in place of P20R104K5-F (50V)?

A: Yes. A104K20X7RH5TAA is a voltage upgrade substitute with identical capacitance (0.1 µF), tolerance (±10%), and temperature coefficient (X7R). The 100V rating is higher than the 50V requirement, providing additional safety margin. Physical dimensions differ (0.118" Dia x 0.197" L vs 0.100" Dia x 0.260" L), requiring PCB layout verification.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life without moisture bake-out requirements. The original P20R104K5-F and substitute C420C104K5R5TA7200 both carry MSL 1 rating, eliminating moisture management concerns during storage and assembly.

Q: Is C412C104J5R5TA suitable as a substitute despite ±5% tolerance?

A: C412C104J5R5TA is electrically compatible (0.1 µF, 50V, X7R) but features tighter ±5% tolerance instead of ±10%. This represents an upgrade in tolerance specification. The part is suitable for applications where improved capacitance accuracy is beneficial. Physical dimensions differ (0.120" Dia x 0.170" L), requiring board space verification.

Q: Which substitute offers the best inventory availability?

A: C420C104K5R5TA7200 (KEMET) provides the highest inventory with 20,100 units in stock, ensuring supply security. A104K20X7RH5TAA (Vishay, 100V upgrade) offers 26,659 units if voltage upgrade is acceptable.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the original P20R104K5-F specification. This ensures regulatory compliance for applications subject to RoHS directives.

Q: What packaging options are available for substitutes?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Bulk, and Tape & Box (TB). Select packaging based on assembly process requirements and order quantities. Cut Tape format is standard for automated pick-and-place assembly.
