5WH103MECAA Equivalent & Substitute Parts

Part Overview

The 5WH103MECAA 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, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production continuity. Substitute parts must maintain electrical performance within acceptable parameters while accommodating modern manufacturing and supply chain availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 5WH103MECAA is determined by the following criteria:

• Capacitance Value: Must be 10000 pF (±20% tolerance acceptable)
• Voltage Rating: Minimum 50V required
• Mounting Configuration: Through-hole radial package mandatory
• Temperature Coefficient: Y5P or superior stability classification acceptable
• Operating Temperature Range: Must encompass or exceed -30°C ~ 85°C

The identified substitute AR215F103K4R meets these criteria with enhanced specifications: improved tolerance (±10%), superior temperature coefficient (X8R), extended operating range (-55°C ~ 150°C), and active product status with automotive-grade certification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The AR215F103K4R is a direct functional substitute for the 5WH103MECAA. Both components share identical capacitance and voltage ratings from the same manufacturer. The substitute offers superior specifications: tighter tolerance (±10% vs ±20%), enhanced temperature stability (X8R vs Y5P), and extended operating range (-55°C ~ 150°C vs -30°C ~ 85°C). The AR215F103K4R maintains active product status with AEC-Q200 automotive qualification and ROHS3 compliance, ensuring long-term supply availability and regulatory alignment. Physical package differences (radial configuration with formed, kinked leads vs straight leads) require PCB layout verification for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can AR215F103K4R directly replace 5WH103MECAA in existing designs?

A: Electrical substitution is valid. Both components provide 10000 pF at 50V. Physical lead configuration differs (formed/kinked vs straight), requiring PCB footprint verification before implementation.

Q: What is the significance of the temperature coefficient change from Y5P to X8R?

A: X8R provides superior capacitance stability across temperature extremes (-55°C to +150°C with ±15% variation) compared to Y5P (-30°C to +85°C with ±20% variation). This represents improved performance for temperature-sensitive applications.

Q: Does the tolerance improvement from ±20% to ±10% affect circuit performance?

A: Tighter tolerance reduces capacitance variation, improving circuit predictability and performance consistency. This is beneficial for applications requiring precise capacitive values.

Q: Are there compliance or regulatory differences between these parts?

A: AR215F103K4R includes AEC-Q200 automotive qualification and ROHS3 compliance, providing enhanced regulatory coverage. Both parts maintain REACH compliance.

Q: What packaging differences exist between these components?

A: 5WH103MECAA features straight leads in a 0.236" diameter disc package. AR215F103K4R uses formed, kinked leads in a 0.200" x 0.125" rectangular radial package. PCB hole spacing and lead bend radius must be verified for mechanical fit.
