Equivalent & Substitute Parts for 5WH103MOCAM

Part Overview

The 5WH103MOCAM 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 with through-hole mounting. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Substitute parts must maintain the core electrical specifications (10000 pF capacitance, 50V minimum voltage rating) while accommodating variations in temperature coefficient, tolerance, and physical dimensions within acceptable engineering parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5WH103MOCAM is determined by the following critical parameters:

• Capacitance: Must be 10000 pF (no deviation)
• Voltage Rating: Minimum 50V (equal or higher ratings are acceptable)
• Mounting Type: Through-hole radial configuration required
• Lead Spacing: 0.197" (5.00mm) standard for compatibility
• Lead Style: Formed leads with kinked configuration

Substitute parts are grouped into three categories based on temperature coefficient and tolerance specifications:

1. Y5P Temperature Coefficient Substitutes (closest match to original): D103K39Y5PF6UJ5R, D103K43Y5PH6UJ5R
2. Z5U Temperature Coefficient Substitutes (alternative dielectric): D103M29Z5UF6UJ5R, D103M29Z5UH6UJ5R, D103M29Z5UH6VJ5R
3. X8R Temperature Coefficient Substitute (enhanced stability): AR215F103K4R

All substitutes maintain 10000 pF capacitance, 50V or higher voltage rating, and through-hole radial mounting with 5.00mm lead spacing.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Closest Match): D103K39Y5PF6UJ5R maintains identical temperature coefficient (Y5P) and tolerance specifications (±10% vs. ±20% original), with extended operating temperature range (-30°C ~ 125°C). This part is active and RoHS3 compliant.

Alternative with Enhanced Voltage Margin: D103K43Y5PH6UJ5R provides the same Y5P temperature coefficient with doubled voltage rating (100V vs. 50V), offering additional design margin. This part is active and RoHS3 compliant.

Voltage-Matched Alternative: D103M29Z5UF6UJ5R matches the original 50V rating with identical ±20% tolerance and maintains 5.00mm lead spacing. Temperature coefficient differs (Z5U vs. Y5P), but capacitance stability remains within acceptable parameters for general-purpose applications. This part is active and RoHS3 compliant.

Higher Voltage Z5U Options: D103M29Z5UH6UJ5R and D103M29Z5UH6VJ5R provide 100V rating with Z5U temperature coefficient and ±20% tolerance. Both are active and RoHS3 compliant, with high inventory availability.

Automotive-Grade Substitute: AR215F103K4R is AEC-Q200 rated with X8R temperature coefficient (-55°C ~ 150°C operating range) and ±10% tolerance. Lead spacing is 0.200" (5.08mm), which is compatible with 5.00mm standard spacing. This part is active and RoHS3 compliant.

All substitute parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute with a higher voltage rating than the original 50V specification?

A: Yes. Higher voltage ratings (100V) provide additional design margin and are electrically compatible. The capacitor will function correctly in circuits designed for 50V operation. Physical dimensions may increase slightly with higher voltage ratings.

Q: What is the difference between Y5P and Z5U temperature coefficients?

A: Y5P (B) specifies capacitance change of ±15% over -30°C ~ 85°C (or -30°C ~ 125°C for active substitutes). Z5U specifies ±20% capacitance change over -30°C ~ 125°C. Both are suitable for general-purpose applications; Z5U provides wider temperature stability range.

Q: Are the lead spacing differences between 5.00mm and 5.08mm significant?

A: The 0.08mm difference (AR215F103K4R at 5.08mm vs. standard 5.00mm) is within typical PCB tolerance and is compatible with standard 5.00mm pitch through-hole layouts. Verify PCB pad spacing during design review.

Q: What does RoHS3 compliance mean for this component?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitutes listed are RoHS3 compliant.

Q: Why is the original 5WH103MOCAM obsolete?

A: Obsolescence indicates the part is no longer manufactured by KYOCERA AVX. Active substitutes from Vishay and KYOCERA AVX provide equivalent or enhanced functionality for new designs and production continuity.

Q: Can I use AR215F103K4R (X8R) as a direct replacement for Y5P applications?

A: X8R temperature coefficient (-55°C ~ 150°C, ±15% capacitance change) provides superior temperature stability compared to Y5P. It is suitable for applications requiring enhanced performance across wider temperature ranges. Verify application requirements before selection.

Q: What is the inventory status of these substitutes?

A: All listed substitutes are in active production with available inventory. D103M29Z5UH6UJ5R has the highest inventory (55,942 pcs), while D103K39Y5PF6UJ5R and D103M29Z5UH6VJ5R have moderate availability (863 and 1,069 pcs respectively).
