Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5WH103MACAA is determined by the following critical parameters:

• Capacitance Value: Must be 10000 pF
• Voltage Rating: Must be 50V or higher
• Mounting Configuration: Through-hole radial mounting required
• Lead Spacing: 0.197" (5.00mm) preferred for direct board compatibility
• Temperature Coefficient: Y5P (B) preferred for thermal stability matching; X8R acceptable with extended operating range

Two substitute parts meet these criteria with varying compliance and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

D103K39Y5PF63L5R provides the closest functional match to the 5WH103MACAA. Both parts share identical temperature coefficient (Y5P), capacitance value, and voltage rating. The substitute offers improved tolerance (±10% versus ±20%), extended operating temperature range (-30°C ~ 125°C), and ROHS3 compliance. Lead spacing matches at 0.197" (5.00mm), ensuring direct board compatibility. This part is currently active in production.

AR215F103K4R offers an alternative with different thermal characteristics. The X8R temperature coefficient provides wider operating range (-55°C ~ 150°C) and superior temperature stability compared to Y5P. However, this part uses formed, kinked leads rather than straight leads, and lead spacing is 0.200" (5.08mm) versus the original 0.197" (5.00mm). This substitution requires verification of board layout tolerance. The part carries AEC-Q200 automotive qualification and is active in production.

Selection between substitutes depends on application thermal requirements and board layout constraints. For direct replacement with minimal design modification, D103K39Y5PF63L5R is preferred. For applications requiring extended temperature range and automotive qualification, AR215F103K4R is suitable with lead spacing verification.

Frequently Asked Questions (FAQ)

Q: Can AR215F103K4R be used directly without board modification?

A: Lead spacing differs by 0.003" (0.08mm) from the original part. Board layout tolerance must be verified. If the PCB accommodates 0.200" (5.08mm) spacing, direct substitution is possible. Otherwise, manual lead adjustment or board rework may be required.

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

A: Y5P (B) provides ±10% capacitance change over -30°C ~ 85°C (or -30°C ~ 125°C for the substitute). X8R provides ±15% capacitance change over -55°C ~ 150°C. X8R offers wider temperature range but with slightly greater capacitance variation. Selection depends on circuit tolerance requirements.

Q: Are both substitutes compatible with the original circuit design?

A: Both substitutes maintain 10000 pF capacitance and 50V voltage rating. D103K39Y5PF63L5R matches the original temperature coefficient and lead spacing exactly. AR215F103K4R requires lead spacing verification but offers extended temperature performance. Circuit functionality is maintained with either substitute provided voltage and capacitance requirements are met.

Q: What is the significance of the tolerance improvement from ±20% to ±10%?

A: The substitute parts offer tighter capacitance tolerance, reducing circuit performance variation. This is beneficial for applications sensitive to capacitance drift but does not affect basic substitution compatibility.

Q: Does product status affect substitution suitability?

A: Both substitute parts are active in production, ensuring long-term availability. The original 5WH103MACAA is obsolete, making substitution necessary for new procurement and ongoing system support.
