Substitute Part Grouping Explanation

Substitution of the 228LBA050M2BC is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance: 2200 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Physical Dimensions: 22.00 mm diameter, 25.00 mm height maximum (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Performance Parameters (Allowable Variation):

• ESR @ 120Hz: Substitute parts may exhibit lower ESR values, indicating improved performance
• Lifetime @ 85°C: Substitute parts may exceed the 2000-hour specification
• Ripple Current: Substitute parts may meet or exceed specified ripple current ratings
• Operating Temperature Range: Must maintain -40°C ~ 85°C minimum specification

The substitute part SLPX222M050A1P3 meets all mandatory equivalence criteria and demonstrates improved performance characteristics in ESR and lifetime ratings.

Engineering Selection Recommendations

Primary Part: 228LBA050M2BC

The 228LBA050M2BC remains the primary selection when available. This part is active in production, ROHS3 compliant, and REACH unaffected. It is suitable for general-purpose applications requiring 2200 µF capacitance at 50 V with through-hole snap-in mounting.

Substitute Part: SLPX222M050A1P3

The SLPX222M050A1P3 is a direct substitute when the primary part is unavailable. Both parts are manufactured within the Cornell Dubilier family and share identical electrical ratings and physical dimensions. The substitute part demonstrates improved performance characteristics:

• Lower ESR (211 mOhm vs. 263.75 mOhm @ 120Hz) reduces heat generation and improves efficiency
• Extended lifetime (3000 Hrs vs. 2000 Hrs @ 85°C) provides enhanced reliability margin

Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements. The substitute part is suitable for direct replacement in PCB designs and applications where the primary part is unavailable. No circuit redesign or board layout modification is required.

Frequently Asked Questions (FAQ)

Q: Can SLPX222M050A1P3 be used as a direct replacement for 228LBA050M2BC?

A: Yes. Both parts share identical capacitance (2200 µF), voltage rating (50 V), tolerance (±20%), lead spacing (10.00 mm), physical dimensions (22.00 mm diameter, 25.00 mm height), and package type (radial, can-style snap-in). The substitute part is electrically and mechanically compatible with existing PCB designs without modification.

Q: What are the differences between these two parts?

A: The primary differences are performance enhancements in the substitute part. SLPX222M050A1P3 exhibits lower ESR (211 mOhm vs. 263.75 mOhm @ 120Hz) and extended lifetime (3000 Hrs vs. 2000 Hrs @ 85°C). Ripple current at 120 Hz is slightly lower (1.93 A vs. 2 A), while high-frequency ripple current remains comparable.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both 228LBA050M2BC and SLPX222M050A1P3 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for electronic component manufacturing and use.

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 10.00 mm (0.394 inches), ensuring compatibility with standard PCB hole patterns designed for this spacing.

Q: Can these parts be used in high-temperature applications?

A: Both parts operate across the temperature range of -40°C to 85°C. The lifetime specification of 2000 Hrs (228LBA050M2BC) and 3000 Hrs (SLPX222M050A1P3) applies at 85°C, the maximum operating temperature. Applications requiring operation above 85°C require alternative capacitor selection.

Q: What does the ±20% tolerance mean?

A: The ±20% tolerance indicates that the actual capacitance value may vary from the nominal 2200 µF by up to 20% in either direction. The acceptable range is 1760 µF to 2640 µF. Both parts share this identical tolerance specification.

Q: Are these capacitors suitable for general-purpose applications?

A: Yes. Both parts are rated for general-purpose applications. The 2200 µF capacitance at 50 V with through-hole snap-in mounting is suitable for power supply filtering, energy storage, and signal coupling in standard electronic equipment.

Q: What is ESR and why is it important?

A: ESR (Equivalent Series Resistance) represents the internal resistance of the capacitor at a specified frequency (120Hz in this case). Lower ESR values indicate reduced heat generation and improved performance in ripple current applications. The substitute part's lower ESR (211 mOhm) provides a performance advantage over the primary part (263.75 mOhm).
