Vishay Cera-Mite 20VLS10-R Equivalent & Substitute Parts

Part Overview

The Vishay Cera-Mite 20VLS10-R is a 10000 pF ceramic capacitor rated for 400VAC with Y5V temperature coefficient, designed for safety applications requiring X2 ratings. This through-hole radial disc capacitor is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

The Vishay Cera-Mite 20VLSS10-R qualifies as a direct substitute based on the following matching electrical and mechanical parameters:

• Identical capacitance value: 10000 pF
• Identical tolerance: ±20%
• Identical voltage rating: 400VAC
• Identical temperature coefficient: Y5V (F)
• Identical operating temperature range: -30°C ~ 125°C
• Identical safety rating: X2
• Identical mounting type: Through Hole
• Identical package type: Radial, Disc
• Identical RoHS compliance: ROHS3 Compliant
• Identical moisture sensitivity level: 1 (Unlimited)

The primary difference is physical size: the substitute part features a smaller footprint (0.531" diameter vs. 0.941" diameter), which may be advantageous for space-constrained applications while maintaining all electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 20VLS10-R and 20VLSS10-R are active production components with identical electrical specifications and safety certifications. Selection between these parts depends on PCB layout constraints:

• Use 20VLS10-R when existing board layouts accommodate the larger 0.941" diameter footprint
• Use 20VLSS10-R when space optimization is required, as the smaller 0.531" diameter provides equivalent electrical performance with reduced board area consumption

Both parts maintain ROHS3 compliance and X2 safety ratings for applications requiring regulatory certification. Lead spacing differences (0.374" vs. 0.252") must be verified against PCB hole patterns during design transition.

Frequently Asked Questions (FAQ)

Q: Can the 20VLSS10-R replace the 20VLS10-R in existing designs?

A: Yes, provided the PCB layout accommodates the smaller lead spacing of 0.252" (6.40mm) versus the original 0.374" (9.50mm). All electrical specifications and safety ratings are identical.

Q: Are there any performance differences between these parts?

A: No. Both parts share identical capacitance, voltage rating, temperature coefficient, and operating temperature range. The only differences are physical dimensions and lead spacing.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 20VLS10-R and 20VLSS10-R are ROHS3 compliant with X2 safety ratings suitable for the same applications.

Q: What is the lead spacing difference and why does it matter?

A: The 20VLS10-R has 0.374" (9.50mm) lead spacing while the 20VLSS10-R has 0.252" (6.40mm) lead spacing. This difference affects PCB hole pattern compatibility and must be confirmed before substitution.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
