Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Capacitance Value: Must be 2200 pF
• Tolerance: Must be ±20%
• Temperature Coefficient: Must be Y5U (E)
• Safety Ratings: Must maintain X1, Y1 classification
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial, Disc
• RoHS Compliance: Must be ROHS3 Compliant

The 440LD22AD-R has two identified substitutes: the 440LD22-R (parametric equivalent from the same manufacturer) and the C931U222MVWDBA7317 (manufacturer-recommended alternative from KEMET). Both parts satisfy the core electrical parameters and safety requirements, though voltage rating and physical dimensions vary as detailed in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

440LD22-R (Vishay Cera-Mite): This substitute is a parametric equivalent with identical electrical specifications and physical dimensions to the main part. Both components are from the same manufacturer series (Cera-Mite 440L) and carry equivalent certifications. Selection between 440LD22AD-R and 440LD22-R is determined by packaging requirements: the main part is supplied in standard packaging while the substitute is available in bulk packaging.

C931U222MVWDBA7317 (KEMET): This manufacturer-recommended alternative maintains all critical electrical parameters (capacitance, tolerance, temperature coefficient, and safety ratings) and extends the operating temperature range to -40°C. However, the voltage rating is reduced to 400VAC, and physical dimensions differ (smaller diameter, different lead spacing, and kinked lead style). This substitute is suitable only for applications where the 400VAC rating is adequate and PCB layout accommodates the different lead spacing and formed lead configuration.

Frequently Asked Questions (FAQ)

Q: Can 440LD22-R be used as a direct replacement for 440LD22AD-R?

A: Yes. Both parts are electrically and mechanically identical with matching capacitance (2200 pF), tolerance (±20%), voltage rating (760VAC), temperature coefficient (Y5U), and physical dimensions. The difference is packaging format only.

Q: Is C931U222MVWDBA7317 a direct substitute?

A: Partial substitution only. The KEMET part maintains all critical electrical parameters but has a reduced voltage rating (400VAC versus 760VAC) and different physical dimensions. Use only in applications where 400VAC rating is sufficient and PCB layout can accommodate the smaller diameter (10.00mm versus 10.90mm) and different lead spacing (10.00mm versus 9.50mm).

Q: What are the key differences between the three parts?

A: The 440LD22AD-R and 440LD22-R are identical except for packaging. The C931U222MVWDBA7317 differs in voltage rating (400VAC), physical size, lead spacing, and lead style (kinked versus straight), though all three maintain the same capacitance, tolerance, and temperature coefficient.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant certification and are suitable for applications requiring RoHS compliance.

Q: What is the operating temperature difference?

A: The 440LD22AD-R and 440LD22-R operate from -30°C to 125°C. The C931U222MVWDBA7317 extends the lower limit to -40°C, providing a wider operating range.
