Equivalent & Substitute Parts for 5WH103SACAI

Part Overview

The 5WH103SACAI is a 10000 pF ceramic capacitor rated at 50V with Y5P temperature coefficient, manufactured by KYOCERA AVX. This radial, disc-type capacitor is designed for general-purpose applications. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support, maintenance, and new design implementations where equivalent performance is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5WH103SACAI is based on the following critical parameters:

• Capacitance Value: 10000 pF (exact match required)
• Voltage Rating: 50V minimum (equal or higher acceptable)
• Mounting Configuration: Through-hole radial package with compatible lead spacing
• Temperature Coefficient: Y5P or equivalent performance class
• Tolerance: Must accommodate circuit design requirements

The substitute part AR215F103K4R meets these core electrical requirements while offering improved specifications in temperature stability (X8R coefficient, -55°C ~ 150°C range) and tighter tolerance (±10% versus -20%, +50%). Both parts maintain 50V voltage rating, identical capacitance value, and through-hole radial mounting configuration with compatible lead spacing.

Engineering Selection Recommendations

The AR215F103K4R serves as a direct functional substitute for the obsolete 5WH103SACAI based on matching electrical specifications and through-hole radial package compatibility. The substitute part offers the following advantages:

• Active Product Status: AR215F103K4R is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Compliance: ROHS3 compliance provides regulatory alignment for new designs and manufacturing processes.
• Improved Temperature Stability: X8R temperature coefficient provides superior capacitance stability across the extended operating range (-55°C ~ 150°C) compared to the Y5P coefficient of the original part.
• Tighter Tolerance: ±10% tolerance reduces circuit design margin requirements compared to the -20%, +50% tolerance of the original part.
• Automotive Qualification: AEC-Q200 rating indicates suitability for automotive applications where applicable.

Lead spacing remains compatible at 0.200" (5.00mm), supporting direct board-level substitution with minimal layout modification.

Frequently Asked Questions (FAQ)

Q: Can AR215F103K4R be used as a direct replacement for 5WH103SACAI in existing designs?

A: Yes. Both parts share identical capacitance (10000 pF) and voltage rating (50V), with compatible through-hole radial mounting and lead spacing. The substitute part's improved temperature coefficient and tighter tolerance provide equal or superior performance in most applications.

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

A: Y5P (Class B) and X8R (Class X) are temperature coefficient classifications that define capacitance variation across operating temperature ranges. X8R provides tighter capacitance stability (±15% across -55°C ~ 150°C) compared to Y5P. Selection depends on circuit requirements for capacitance stability at temperature extremes.

Q: Are the lead spacings compatible between these parts?

A: Lead spacing is nominally compatible at 0.197" (5.00mm) for the original part and 0.200" (5.00mm) for the substitute. This 0.003" difference is within standard PCB tolerance for through-hole radial component placement and does not require board redesign.

Q: What compliance certifications apply to the substitute part?

A: AR215F103K4R is ROHS3 compliant and carries AEC-Q200 automotive qualification. The original 5WH103SACAI is REACH Unaffected. Both parts are classified as EAR99 for export control purposes.

Q: Is inventory availability a consideration for this substitution?

A: Yes. AR215F103K4R is currently in active production with 1344 units in stock, whereas 5WH103SACAI is obsolete with limited remaining inventory (757 units). For new designs and long-term support, AR215F103K4R ensures sustained component availability.
