Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30LVD22SN-R is determined by strict equivalence across the following critical parameters: capacitance value (2200 pF), tolerance (±20%), voltage rating (400VAC), temperature coefficient (Y5U), operating temperature range (-30°C to 125°C), safety ratings (X1, Y2), mounting type (Through Hole), and package configuration (Radial, Disc). All identified substitutes maintain these core electrical and mechanical specifications. Physical dimensions vary between substitute options, which affects board layout compatibility but does not alter electrical performance within the specified parameters.

The substitute parts are classified as follows:

Direct Manufacturer Substitutes: 30LVSD22-R and 30LVSD22XY-R are active production parts from the Cera-Mite 30LVS series with identical electrical specifications but reduced physical dimensions (0.331" diameter vs. 0.402" diameter).

Parametric Equivalent: 30LVD22-R is an active production part from the Cera-Mite 30LV series with identical electrical specifications and matching physical dimensions to the main part.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical equivalence to the 30LVD22SN-R across all critical safety and performance parameters. Selection between substitutes depends on physical space constraints and board layout requirements.

For direct dimensional replacement: The 30LVD22-R is the optimal choice, offering identical physical dimensions (0.402" diameter, 0.528" height) to the original part while maintaining active production status. This part requires no PCB layout modifications.

For space-constrained applications: The 30LVSD22-R and 30LVSD22XY-R provide compact alternatives with reduced physical dimensions (0.331" diameter, 0.457" height) while preserving all electrical specifications. These parts are suitable for designs where board space optimization is required, provided the PCB layout accommodates the smaller footprint.

All substitute parts carry ROHS3 compliance and MSL 1 rating, ensuring compatibility with modern manufacturing processes and long-term storage without moisture sensitivity concerns.

Frequently Asked Questions (FAQ)

Q: Can the 30LVSD22-R or 30LVSD22XY-R be used as direct replacements for the 30LVD22SN-R without circuit modification?

A: Yes. All three parts share identical electrical specifications: 2200 pF capacitance, ±20% tolerance, 400VAC rating, Y5U temperature coefficient, and -30°C to 125°C operating range. Circuit performance remains unchanged. Physical dimensions differ, requiring PCB layout verification for the smaller substitute options.

Q: What is the difference between 30LVSD22-R and 30LVSD22XY-R?

A: Both parts are electrically and mechanically identical. They differ only in packaging designation. Both are active production parts from the Cera-Mite 30LVS series with the same electrical performance and physical dimensions.

Q: Why is the 30LVD22SN-R classified as obsolete?

A: The 30LVD22SN-R is an older production variant. The 30LVD22-R (active status) serves as the current production equivalent with identical specifications and dimensions. The 30LVSD22-R and 30LVSD22XY-R represent newer compact variants within the Cera-Mite product line.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All parts maintain ROHS3 compliance, X1/Y2 safety ratings, and MSL 1 moisture sensitivity level. Regulatory and compliance status is uniform across all options.

Q: What is the lead spacing specification, and does it affect substitution?

A: Lead spacing is 0.252" (6.40mm) for all parts, including the main part and all substitutes. This parameter is consistent and does not affect substitution compatibility.

Q: Can I use the compact 30LVSD22-R in a design originally specified for the 30LVD22SN-R?

A: Electrical substitution is valid. Physical substitution requires PCB layout review. The 30LVSD22-R is 0.071" smaller in diameter and 0.071" shorter in height. Verify that the reduced footprint fits within the available board space and does not conflict with adjacent components.
