5WH103KOCAL Equivalent & Substitute Parts

Part Overview

The 5WH103KOCAL is a 10000 pF ceramic capacitor rated at 50V with Y5P temperature coefficient, manufactured by KYOCERA AVX. This radial, disc-type component is designed for general-purpose applications with through-hole mounting. The part is currently obsolete, making identification of functionally equivalent substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 5WH103KOCAL is determined by the following core parameters:

Capacitance Value: Must be 10000 pF (±10% tolerance acceptable)
Voltage Rating: Minimum 50V (higher ratings are acceptable for derating purposes)
Temperature Coefficient: Y5P (B) preferred for thermal stability matching; X8R acceptable with extended operating range
Mounting Type: Through Hole required
Package Configuration: Radial, Disc format with 0.197" (5.00mm) lead spacing
Lead Style: Formed Leads - Kinked

Three substitute parts meet these criteria with varying compliance and availability profiles.

Engineering Selection Recommendations

AR215F103K4R (KYOCERA AVX SkyCap® AR Series): This substitute offers the same manufacturer lineage as the original part with active product status. The X8R temperature coefficient provides superior thermal stability (-55°C ~ 150°C) compared to the Y5P specification. AEC-Q200 automotive qualification is included. Lead spacing tolerance of 0.200" (5.08mm) versus the original 0.197" (5.00mm) represents a 0.08mm variance and is within standard PCB design tolerances for radial component placement. ROHS3 compliance ensures regulatory alignment. Suitable for applications requiring extended temperature performance and automotive-grade reliability.

D103K39Y5PF6TJ5R (Vishay Beyschlag/Draloric/BC Components D Series): This substitute maintains the Y5P temperature coefficient matching the original specification. Lead spacing and package configuration are identical to the main part. Operating temperature range extends to 125°C. ROHS3 compliance and Tape & Reel packaging support high-volume production environments. Suitable for direct functional replacement in general-purpose applications where Y5P thermal characteristics are required.

D103K43Y5PH6TJ5R (Vishay Beyschlag/Draloric/BC Components D Series): This substitute provides the same Y5P temperature coefficient with elevated voltage rating (100V versus 50V). The higher voltage rating enables component derating in circuits where margin is beneficial. Operating temperature extends to 125°C. Physical size increases to 0.433" diameter (11.00mm) compared to the original 0.236" (6.00mm), requiring PCB layout verification. ROHS3 compliance and Cut Tape packaging are provided. Suitable for applications where voltage derating and extended thermal range are advantageous.

Frequently Asked Questions (FAQ)

Q: Can AR215F103K4R be used as a direct replacement for 5WH103KOCAL?

A: AR215F103K4R is functionally equivalent for capacitance, tolerance, and voltage rating. The X8R temperature coefficient differs from the original Y5P specification, providing superior thermal stability. Lead spacing tolerance (0.200" versus 0.197") is within standard PCB design margins. Substitution is valid where extended temperature performance (-55°C ~ 150°C) is acceptable or beneficial.

Q: What is the difference between Y5P and X8R temperature coefficients?

A: Y5P (B) specifies capacitance change of ±15% over the operating temperature range -30°C ~ 85°C. X8R specifies capacitance change of ±15% over the wider range -55°C ~ 150°C. X8R provides superior stability across extended temperature extremes but may exhibit different frequency response characteristics. Selection depends on circuit thermal requirements.

Q: Are the Vishay D103K parts pin-compatible with the KYOCERA AVX 5WH103KOCAL?

A: Both D103K39Y5PF6TJ5R and D103K43Y5PH6TJ5R maintain 0.197" (5.00mm) lead spacing identical to the original part, ensuring PCB footprint compatibility. D103K43Y5PH6TJ5R exhibits larger physical dimensions (0.433" diameter versus 0.236"), requiring clearance verification on the PCB. Lead style (Formed Leads - Kinked) is consistent across all parts.

Q: What packaging options are available for production?

A: AR215F103K4R is supplied in Bulk packaging. D103K39Y5PF6TJ5R is supplied in Tape & Reel (TR) format, suitable for automated assembly. D103K43Y5PH6TJ5R is supplied in Cut Tape (CT) format. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. AR215F103K4R, D103K39Y5PF6TJ5R, and D103K43Y5PH6TJ5R are all ROHS3 compliant, meeting current environmental and regulatory requirements.
