Frequently Asked Questions (FAQ)

Q: Can C410C103M1U5TA replace P10U103M1-F directly on the PCB?

A: C410C103M1U5TA is electrically equivalent but has a slightly reduced diameter (0.095" vs. 0.100"). Verify PCB layout clearances and component spacing. If diameter reduction creates no mechanical interference, this substitution is valid. C410C103M1U5TA7200 maintains identical diameter and is preferred for direct mechanical replacement.

Q: What is the difference between Z5U and C0G temperature coefficients?

A: Z5U dielectric provides ±20% capacitance change across 10°C ~ 85°C operating range. C0G/NP0 dielectric provides superior stability with minimal capacitance change across -55°C ~ 125°C operating range. C0G substitutes are upgrades offering extended temperature performance and tighter tolerance specifications.

Q: Can I use C420C103F2G5TA (200V) in place of P10U103M1-F (100V)?

A: Yes. Higher voltage rating components are acceptable substitutes for lower voltage applications. C420C103F2G5TA provides 200V rating, ±1% tolerance, and C0G dielectric. Physical dimensions are slightly larger (0.100" Dia x 0.200" L vs. 0.100" Dia x 0.170" L). Verify PCB layout accommodates increased length.

Q: What does "Active" product status mean?

A: Active status indicates the component is currently manufactured, stocked, and supported by the supplier. All recommended KEMET substitutes carry Active status, ensuring availability and supply chain continuity. The original P10U103M1-F is Obsolete, meaning CDE no longer manufactures this part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended KEMET substitutes maintain ROHS3 compliance matching the original P10U103M1-F specification. Compliance certifications are identical across all substitute options.

Q: What packaging options are available?

A: C410C103M1U5TA7200 is supplied in Cut Tape (CT) packaging with 19510 units in stock. C410C103M1U5TA and upgrade variants are supplied in Bulk packaging. Select packaging based on production volume and assembly process requirements.

Q: Can I substitute Z5U with X7R dielectric?

A: Yes. C410C103K1R5TA provides X7R dielectric with ±10% tolerance and extended -55°C ~ 125°C operating range. X7R offers different temperature stability characteristics than Z5U. Verify circuit design requirements for temperature coefficient performance before substitution.

Q: What is the difference between ±20% and ±1% tolerance?

A: P10U103M1-F tolerance is ±20%, meaning actual capacitance can vary from 8000 pF to 12000 pF. C0G upgrade substitutes offer ±1% tolerance, meaning actual capacitance varies from 9900 pF to 10100 pF. Tighter tolerance is beneficial for precision circuits but not required for general-purpose applications.
