• Package: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" / 10.00mm (exact match required)
• Diameter: 0.984" / 25.00mm (exact match required)
• Mounting: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Functional Equivalent (Higher Voltage Rating):

• Same capacitance, tolerance, and package specifications
• Voltage rating exceeds 50 V minimum requirement
• Maintains identical mechanical footprint and lead configuration
• Suitable for applications where higher voltage margin is acceptable

Compliance Considerations:

• Product status (Active vs. Obsolete) affects long-term availability

Engineering Selection Recommendations

228LMX050M2CC - Recommended Direct Replacement:

The 228LMX050M2CC is the primary equivalent for the obsolete 228LMU050M2CC. Both components share identical electrical ratings (2200 µF, 50 V, ±20% tolerance) and mechanical specifications (radial snap-in package, 10.00mm lead spacing, 25.00mm diameter). The 228LMX050M2CC is currently in active production status, ensuring procurement continuity. The LMX series demonstrates improved reliability with 5000 hours lifetime at 105°C compared to the LMU series 2000 hours rating. Both components maintain equivalent series resistance of approximately 150.7 mOhm at 120 Hz. The 228LMX050M2CC carries ROHS3 compliance certification, meeting current regulatory requirements. Inventory availability is documented at 689 pieces.

SLPX222M063C1P3 - Functional Equivalent with Higher Voltage Rating:

The SLPX222M063C1P3 provides functional equivalence with a higher voltage rating of 63 V, compared to the 50 V specification of the main part. This component maintains identical capacitance (2200 µF), tolerance (±20%), and mechanical form factor (radial snap-in, 10.00mm lead spacing, 25.00mm diameter). The SLPX series is in active production with ROHS3 compliance. The higher voltage rating provides additional design margin in applications where voltage stress is a consideration. However, the SLPX222M063C1P3 has a reduced maximum seated height of 0.984" (25.00mm) compared to 1.063" (27.00mm) for the main part, and a lower maximum operating temperature of 85°C versus 105°C. The ESR is higher at 181 mOhm at 120 Hz. Selection of this substitute requires verification that the reduced height and lower temperature rating are compatible with the application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 228LMX050M2CC be used as a direct replacement for the 228LMU050M2CC?

A: Yes. The 228LMX050M2CC is a direct equivalent. Both components have identical capacitance (2200 µF), voltage rating (50 V), tolerance (±20%), and mechanical specifications including lead spacing (10.00mm), diameter (25.00mm), and package type (radial snap-in). The 228LMX050M2CC is in active production, whereas the 228LMU050M2CC is obsolete. The LMX series offers improved lifetime rating (5000 hours at 105°C versus 2000 hours).

Q: What is the difference between the 228LMU050M2CC and SLPX222M063C1P3?

A: The primary difference is the voltage rating: SLPX222M063C1P3 is rated for 63 V compared to 50 V for the 228LMU050M2CC. Both share the same capacitance (2200 µF), tolerance (±20%), and lead spacing (10.00mm). However, the SLPX222M063C1P3 has a lower maximum seated height (0.984" versus 1.063") and a lower maximum operating temperature (85°C versus 105°C). The SLPX series also has higher ESR (181 mOhm at 120 Hz versus 150.71 mOhm).

Q: Can I use the SLPX222M063C1P3 in place of the 228LMU050M2CC?

A: The SLPX222M063C1P3 is mechanically compatible (same lead spacing and diameter) and electrically compatible for applications operating at or below 50 V. However, the reduced maximum seated height (0.984" versus 1.063") must be verified against PCB clearance requirements. The lower maximum operating temperature of 85°C must be confirmed as acceptable for the application. If the application requires operation above 85°C or the additional 2mm height is critical, the 228LMX050M2CC is the preferred substitute.

Q: Are there any compliance differences between these parts?

A: The 228LMX050M2CC and SLPX222M063C1P3 are both ROHS3 compliant and REACH unaffected. The 228LMU050M2CC (obsolete) does not have documented RoHS status. Both active production parts meet current regulatory requirements for new designs.

Q: What is the significance of the ESR (Equivalent Series Resistance) values?

A: ESR affects ripple current handling and heat generation. The 228LMU050M2CC and 228LMX050M2CC have nearly identical ESR values (150.71 mOhm and 150.7 mOhm respectively at 120 Hz), ensuring equivalent performance in ripple current applications. The SLPX222M063C1P3 has higher ESR (181 mOhm), which may result in increased heat generation under high ripple current conditions. Applications with stringent ripple current requirements should prioritize the 228LMX050M2CC.

Q: How do the lifetime ratings affect part selection?

A: The 228LMX050M2CC offers 5000 hours lifetime at 105°C, compared to 2000 hours for the 228LMU050M2CC. The SLPX222M063C1P3 offers 3000 hours at 85°C. For applications requiring extended operational life at elevated temperatures, the 228LMX050M2CC provides superior reliability. The SLPX222M063C1P3 lifetime rating is specified at a lower temperature (85°C), making direct comparison with the other parts difficult for applications operating at 105°C.

Q: Are these parts suitable for snap-in mounting applications?

A: Yes. All three parts are specified as radial, can snap-in package with through-hole mounting. The 10.00mm lead spacing and 25.00mm diameter are consistent across all parts, ensuring compatibility with standard snap-in PCB footprints. The height difference between the 228LMU050M2CC / 228LMX050M2CC (1.063") and SLPX222M063C1P3 (0.984") must be verified against specific PCB design clearances.
