P10R102K1 Equivalent & Substitute Parts Reference

Part Overview

The Cornell Dubilier Electronics P10R102K1 is a 1000 pF ±10% 100V ceramic capacitor with X7R temperature coefficient in axial through-hole configuration. This component is classified as obsolete, necessitating identification of equivalent and upgraded alternatives for ongoing design support and procurement continuity. The part operates across -55°C to 125°C and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range.

Operating Temperature	-55°C to 125°C	Minimum range requirement
Mounting Type	Through Hole Axial	Must match for PCB compatibility
Package/Case	Axial	Physical form factor; dimensional compatibility required
RoHS Status	Non-compliant	Compliance requirement depends on application

Substitute Part Grouping Explanation

Substitution logic is based on the following criteria:

Direct Equivalents (Same Electrical Specifications): Parts matching 1000 pF capacitance, ±10% tolerance, 100V minimum voltage rating, X7R temperature coefficient, and -55°C to 125°C operating range. These parts are functionally interchangeable with the P10R102K1 in the original circuit.

Dimensional Compatibility: Direct equivalents must accommodate axial through-hole mounting. The original P10R102K1 has dimensions of 0.100" Dia × 0.170" L (2.54mm × 4.32mm). Substitute parts with smaller dimensions (0.091" Dia × 0.118" L) are physically compatible with PCB layouts designed for the larger original part, as they occupy less board space.

Upgraded Alternatives (Enhanced Specifications): Parts with improved electrical characteristics including tighter tolerance (±5%, ±2%, ±1%), higher voltage ratings (200V, 250V), or superior temperature coefficients (C0G/NP0 instead of X7R). These parts exceed the original specifications and are suitable for applications requiring enhanced performance or compliance requirements.

Compliance Considerations: RoHS3 compliant parts are preferred for new designs and regulated applications. Parts with REACH Unaffected status are suitable for unrestricted use.

Engineering Selection Recommendations

For Direct Replacement (Electrical Equivalence):

SA101C102KAA is the primary direct substitute. It maintains identical electrical specifications (1000 pF, ±10%, 100V, X7R, -55°C to 125°C) with matching physical dimensions (0.100" × 0.170"). The part is active in production and ROHS3 compliant, providing compliance advantage over the obsolete P10R102K1. Cut Tape packaging supports both prototype and production workflows.

SA051C102KAA and SA051C102KAA-LF are functionally equivalent alternatives with reduced physical dimensions (0.091" × 0.118"). These parts occupy less PCB space while maintaining all electrical specifications. SA051C102KAA-LF offers the highest inventory availability (1112 pcs) and ROHS3 compliance.

For Applications Requiring Enhanced Specifications:

KEMET AxiMax 400 series parts (C410C102F2G5TA, C410C102FAG5TA, C410C102G2G5TA, C410C102GAG5TA, C410C102J2G5TA) provide upgraded performance with C0G/NP0 temperature coefficient, delivering superior capacitance stability across temperature extremes. These parts support higher voltage ratings (200V or 250V) and tighter tolerances (±1%, ±2%, ±5%), suitable for precision circuits and high-reliability applications. All KEMET alternatives are ROHS3 compliant.

KEMET ACA25D102JGS offers 100V rating with ±5% tolerance and C0G/NP0 coefficient, extending operating temperature to 200°C for high-temperature applications.

Compliance and Inventory Considerations:

For new designs and regulated applications, prioritize ROHS3 compliant parts. SA101C102KAA, SA051C102KAA, and SA051C102KAA-LF from KYOCERA AVX meet this requirement. All KEMET alternatives are ROHS3 compliant. Current inventory levels support immediate procurement across all recommended substitutes.

Frequently Asked Questions (FAQ)

Q: Can SA051C102KAA replace P10R102K1 directly in existing PCB layouts?

A: SA051C102KAA is electrically equivalent but physically smaller (0.091" × 0.118" vs. 0.100" × 0.170"). It will fit PCB holes designed for the larger P10R102K1 without modification. However, verify that the reduced physical size does not affect mechanical stability or thermal management in the specific application.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance variation across -55°C to 125°C. C0G/NP0 provides ±30 ppm/°C, delivering superior stability. KEMET alternatives with C0G/NP0 are suitable for precision applications where capacitance drift must be minimized.

Q: Are KEMET parts with 200V or 250V ratings suitable for 100V circuits?

A: Yes. Higher voltage ratings provide design margin and are electrically compatible with 100V circuits. The capacitor will not be stressed and will exhibit improved reliability. Verify that physical dimensions accommodate the PCB layout.

Q: What is the significance of packaging type (Tape & Reel vs. Cut Tape vs. Bulk)?

A: Tape & Reel and Cut Tape packaging support automated assembly processes. Bulk packaging is suitable for manual assembly or prototype builds. Select packaging based on production volume and assembly method. All packaging types contain identical components.

Q: Is RoHS3 compliance mandatory for my application?

A: RoHS3 compliance is required for products sold in the European Union and many regulated markets. For legacy systems or non-regulated applications, RoHS non-compliant parts remain functional. Verify compliance requirements with your design standards and regional regulations.

Q: Can I use SA051C102KAC-LG (RoHS non-compliant) instead of SA101C102KAA (RoHS3 compliant)?

A: Both parts are electrically equivalent. Selection depends on compliance requirements. SA051C102KAC-LG is suitable only for applications without RoHS compliance mandates. SA101C102KAA is preferred for regulated applications and new designs.

Q: What inventory levels support production schedules?

A: SA051C102KAA-LF offers the highest availability (1112 pcs), followed by SA101C102KAA (894 pcs) and C410C102FAG5TA (2824 pcs). Verify inventory status with your supplier for current availability and lead times.
