5WH103MECAD Equivalent & Substitute Parts

Part Overview

The 5WH103MECAD is a 10000 pF ceramic capacitor rated at 50V with Y5P temperature coefficient, manufactured by KYOCERA AVX in a radial, disc configuration. This component is classified as obsolete, making identification of suitable equivalent parts essential for ongoing system support and component procurement.

The Y5P temperature coefficient specification indicates a capacitance change of -82% to +22% across the operating temperature range of -30°C to 85°C. Due to the obsolete status, direct replacement with active production alternatives is necessary for new designs and inventory replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5WH103MECAD is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 10000 pF
• Voltage rating: 50V (equal or higher acceptable)
• Mounting type: Through Hole
• Package configuration: Radial

Allowable Variations:

• Temperature coefficient: X8R is acceptable as a substitute for Y5P, provided the operating temperature range of the application does not exceed -55°C to 150°C
• Tolerance: ±10% is tighter than the original ±20% specification and is acceptable
• Lead configuration: Formed leads with kinked style are compatible with radial footprints
• Physical dimensions: Minor variations in size and height are acceptable if the component fits within the PCB layout constraints

The AR215F103K4R meets all mandatory parameters and represents an active production alternative with improved temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AR215F103K4R is the recommended substitute for the 5WH103MECAD based on the following factors:

Product Status: The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance and Certifications: The AR215F103K4R carries AEC-Q200 automotive qualification and ROHS3 compliance, providing enhanced reliability documentation suitable for regulated applications.

Electrical Compatibility: Both parts share identical capacitance (10000 pF) and voltage rating (50V). The X8R temperature coefficient of the substitute provides superior temperature stability across a wider operating range (-55°C to 150°C versus -30°C to 85°C), making it suitable for applications requiring extended temperature performance.

Mechanical Compatibility: Both components are through-hole radial configurations with compatible lead spacing (0.236" for main part, 0.200" for substitute). Physical dimension differences are minor and do not preclude direct substitution in standard PCB layouts.

Tolerance Consideration: The substitute's ±10% tolerance is tighter than the original ±20%, resulting in improved capacitance accuracy without introducing compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can AR215F103K4R directly replace 5WH103MECAD in existing designs?

A: Yes. Both components share the same capacitance value (10000 pF), voltage rating (50V), and through-hole radial package configuration. Lead spacing is compatible with standard radial footprints. Physical dimensions are similar, and the substitute's improved temperature coefficient and tighter tolerance provide equivalent or superior performance.

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

A: Y5P specifies a capacitance change of -82% to +22% over -30°C to 85°C. X8R specifies ±15% capacitance change over -55°C to 150°C. X8R provides superior stability across a wider temperature range, making it suitable for applications requiring consistent performance in variable thermal environments.

Q: Are there any lead configuration concerns with the kinked leads on the substitute?

A: No. The AR215F103K4R's formed leads with kinked style are standard for radial ceramic capacitors and are compatible with through-hole PCB designs. The kinked configuration aids in component retention during assembly.

Q: Does the tighter tolerance of the substitute affect compatibility?

A: No. The AR215F103K4R's ±10% tolerance is tighter than the original ±20% specification. This results in improved capacitance accuracy and does not introduce compatibility issues. Applications designed for ±20% tolerance will function correctly with ±10% components.

Q: What is the inventory status for these parts?

A: The 5WH103MECAD has 670 pieces in stock but is obsolete. The AR215F103K4R has 1344 pieces in stock and is in active production, providing superior long-term availability.
