Substitute Part Grouping Explanation

Substitute parts for the SLP221M200A3P3 are grouped based on the following criteria:

Direct Equivalent (SLP221M200A1P3): This substitute maintains identical electrical specifications including 220 µF capacitance, 200 V voltage rating, ±20% tolerance, 905 mOhm ESR, and 3000-hour lifetime at 105°C. The primary difference is physical height: the substitute measures 0.984" (25.00 mm) seated height compared to 1.181" (30.00 mm) for the main part. Both share identical lead spacing (0.394"), case diameter (0.866"), and mounting configuration. This substitute is applicable in space-constrained applications where reduced axial height is acceptable.

Voltage Upgrade (SLP221M250A3P3): This substitute increases the voltage rating from 200 V to 250 V while maintaining all other core specifications: 220 µF capacitance, ±20% tolerance, 905 mOhm ESR, and 3000-hour lifetime at 105°C. Physical dimensions remain identical to the main part (0.866" diameter, 1.181" height, 0.394" lead spacing). This upgrade substitute provides enhanced voltage margin for applications requiring higher voltage headroom without changing footprint or mounting characteristics.

All substitutes are manufactured by Cornell Dubilier Electronics (CDE), belong to the SLP0712TE series, maintain ROHS3 compliance, and are classified as Active products.

Engineering Selection Recommendations

SLP221M200A1P3 Selection Criteria: Select this direct equivalent when PCB layout constraints require reduced component height. The 0.984" seated height provides 0.197" (5.00 mm) reduction compared to the main part while preserving all electrical characteristics. This substitute is suitable for applications where vertical clearance is limited and voltage requirements remain at 200 V. Both parts maintain identical lead spacing and case diameter, ensuring footprint compatibility on existing PCB designs.

SLP221M250A3P3 Selection Criteria: Select this voltage upgrade when circuit design requires enhanced voltage margin or when operating conditions approach the 200 V rating limit. The 250 V rating provides 25% additional voltage headroom while maintaining identical physical dimensions and electrical performance. This substitute is applicable in designs where voltage transients or margin requirements exceed the original 200 V specification. The upgrade does not alter PCB footprint or mounting requirements.

Compliance and Certification: All three parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. All parts are classified as Active products with unlimited moisture sensitivity level (MSL 1). Selection between these parts does not introduce compliance or regulatory concerns.

Frequently Asked Questions (FAQ)

Q: Can SLP221M200A1P3 be used as a direct replacement for SLP221M200A3P3?

A: Yes, SLP221M200A1P3 is a direct electrical equivalent with identical capacitance (220 µF), voltage rating (200 V), tolerance (±20%), ESR (905 mOhm), and lifetime (3000 Hrs @ 105°C). The primary difference is physical height: 0.984" versus 1.181". This substitute is compatible if PCB clearance permits the reduced height and if lead spacing (0.394") and case diameter (0.866") match the original design.

Q: What is the advantage of using SLP221M250A3P3 over SLP221M200A3P3?

A: SLP221M250A3P3 provides a 250 V voltage rating compared to 200 V, offering 25% additional voltage margin. All other specifications remain identical: 220 µF capacitance, ±20% tolerance, 905 mOhm ESR, 3000-hour lifetime, and physical dimensions. This upgrade is beneficial in applications where voltage transients or design margins require higher voltage headroom without changing component footprint or mounting configuration.

Q: Are all three parts pin-compatible?

A: Yes, all three parts share identical lead spacing (0.394" / 10.00 mm) and mounting type (through-hole, radial snap-in). PCB hole patterns and lead positions are compatible across all three parts. Physical height differences do not affect electrical connectivity or pin compatibility.

Q: Do these substitutes affect circuit performance or reliability?

A: No. All three parts maintain identical ESR (905 mOhm @ 120Hz), ripple current ratings, and thermal lifetime specifications (3000 Hrs @ 105°C). Operating temperature range (-25°C to 105°C) is consistent across all parts. Substitution does not alter circuit performance, filtering characteristics, or component reliability.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited moisture sensitivity). Substitution between these parts does not introduce compliance, environmental, or export classification concerns.

Q: What inventory status should be considered when selecting a substitute?

A: Current inventory levels are: SLP221M200A3P3 (946 pcs), SLP221M200A1P3 (1166 pcs), and SLP221M250A3P3 (2634 pcs). Availability may influence substitute selection when immediate procurement is required.
