Equivalent & Substitute Parts for 440LD22UG-R

Part Overview

The Vishay Cera-Mite 440LD22UG-R is a 2200 pF ceramic capacitor rated for 760VAC with Y5U temperature coefficient, designed for safety-critical applications. This radial, disc-type component is actively manufactured and widely used in AC filtering and coupling circuits requiring high voltage performance. Alternative equivalent parts may be required due to inventory availability, lead time optimization, or specific packaging requirements in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 440LD22UG-R is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±20% (exact match required)
• Temperature coefficient: Y5U (E) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Disc (exact match required)
• Safety ratings: X1, Y1 (exact match required)

Secondary Considerations:

• Voltage rating: Must meet or exceed 760VAC application requirement
• Operating temperature range: Must encompass -30°C ~ 125°C
• RoHS compliance: ROHS3 Compliant status maintained

The 440LD22-R (Vishay Cera-Mite) qualifies as a parametric equivalent with identical electrical and mechanical specifications. The C931U222MVWDBA7317 (KEMET) meets all primary matching criteria but operates at a reduced voltage rating of 400VAC, which does not satisfy the 760VAC requirement and therefore is not suitable for direct substitution in this application.

Parameter Comparison

Engineering Selection Recommendations

440LD22-R (Vishay Cera-Mite): This part is the direct parametric equivalent to the 440LD22UG-R. Both components share identical electrical specifications, safety ratings, and mechanical dimensions. The 440LD22-R maintains ROHS3 compliance and active product status. Selection of this substitute is appropriate when inventory or lead time considerations require an alternative source within the same manufacturer series.

C931U222MVWDBA7317 (KEMET): This part does not qualify as a suitable substitute for the 440LD22UG-R due to insufficient voltage rating. The 400VAC rating falls below the 760VAC requirement of the application. Although this component shares identical capacitance, tolerance, temperature coefficient, and safety ratings, the voltage specification mismatch presents a functional incompatibility that cannot be overlooked in safety-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 440LD22-R be used as a direct replacement for the 440LD22UG-R?

A: Yes. The 440LD22-R is a parametric equivalent with identical capacitance (2200 pF), tolerance (±20%), voltage rating (760VAC), temperature coefficient (Y5U), operating temperature range (-30°C ~ 125°C), mounting type (Through Hole), package configuration (Radial, Disc), and safety ratings (X1, Y1). Both components are manufactured by Vishay Cera-Mite within the same 440L series.

Q: Why is the C931U222MVWDBA7317 not recommended as a substitute?

A: The C931U222MVWDBA7317 operates at 400VAC, which does not meet the 760VAC voltage requirement of the application. Although this KEMET component matches all other critical parameters, the voltage rating deficiency makes it unsuitable for direct substitution in circuits designed for 760VAC operation.

Q: Are there packaging differences between the 440LD22UG-R and 440LD22-R?

A: The primary packaging difference is the supply format. The 440LD22UG-R is supplied in Bulk packaging, while the 440LD22-R is also supplied in Bulk. Both components maintain identical physical dimensions: 0.429" diameter (10.90mm), 0.555" maximum seated height (14.10mm), and 0.374" lead spacing (9.50mm).

Q: What compliance certifications apply to these components?

A: All three components listed maintain ROHS3 compliance and REACH Unaffected status. The 440LD22UG-R and 440LD22-R carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Both components are classified under ECCN EAR99 for export purposes.

Q: Can circuit design be modified to accommodate the C931U222MVWDBA7317?

A: No modification of circuit design can compensate for the voltage rating deficiency. The 400VAC rating of the C931U222MVWDBA7317 represents a fundamental electrical limitation that cannot be overcome through design changes when the application requires 760VAC operation.
