Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPW102M2AP25V-W is determined by the following critical parameters:

Primary Compatibility Criteria:

• Capacitance value: 1000 µF (exact match required)
• Voltage rating: Equal to or greater than 100 V
• Tolerance: ±20% (standard for aluminum electrolytic capacitors)
• Package type: Radial, Can - Snap-In
• Mounting type: Through Hole
• Lead spacing: 0.394" (10.00 mm)
• Polarization: Polar

Secondary Compatibility Considerations:

• Operating temperature range: -40°C to 85°C minimum
• Physical dimensions: Diameter and height must accommodate PCB layout constraints
• ESR and ripple current ratings: Application-dependent performance parameters

Substitute parts are grouped into two categories based on voltage rating:

Category A - Direct Voltage Match (100 V):

• 380LX102M100H022
• SLPX102M100A3P3

Category B - Higher Voltage Rating (160 V and 180 V):

• SLPX102M160E3P3
• 380LQ102M180K012

All substitute parts maintain the same capacitance, tolerance, package configuration, and lead spacing as the original part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (100 V Applications):

The 380LX102M100H022 and SLPX102M100A3P3 are functionally equivalent to the LPW102M2AP25V-W at the same voltage rating. Both parts are active products with ROHS3 compliance and extended lifetime ratings (3000 Hrs @ 85°C versus 1000 Hrs for the original part). The 380LX102M100H022 offers improved ESR performance (220 mOhm) and is available in higher quantity (4133 Pcs). The SLPX102M100A3P3 provides the largest inventory availability (17457 Pcs) with comparable ESR (265 mOhm).

Physical dimension differences exist: both 100 V alternatives feature a smaller diameter (0.866" vs. 1.181") but greater height. PCB layout verification is required to confirm fit within existing mounting footprints.

For Higher Voltage Applications:

The SLPX102M160E3P3 (160 V) and 380LQ102M180K012 (180 V) provide voltage margin above the original 100 V specification. These parts are suitable for applications requiring overvoltage protection or operating in elevated voltage environments. Both deliver lower ESR (199 mOhm) and higher ripple current capacity compared to the original part.

The SLPX102M160E3P3 maintains the same physical diameter as the original part (1.181") with matching height (1.181"), offering the closest form factor compatibility. The 380LQ102M180K012 provides the highest voltage rating with slightly reduced height (1.063").

Compliance and Supply Chain:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. All are classified as active products with established supply availability, eliminating obsolescence risk associated with the original LPW102M2AP25V-W.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor (160 V or 180 V) in place of the 100 V original part?

A: Yes. Higher voltage-rated capacitors are electrically compatible in circuits designed for lower voltages. The circuit will operate normally, as the capacitor will not be stressed beyond its design limits. However, physical dimensions must be verified for PCB fit.

Q: What is the significance of ESR differences between the original and substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. Lower ESR values (199-220 mOhm in substitutes versus 332 mOhm in original) indicate improved performance characteristics. Substitutes with lower ESR will generate less heat and handle ripple current more efficiently.

Q: Why do some substitute parts have different physical dimensions?

A: The 380LX102M100H022 and SLPX102M100A3P3 use more compact can designs (0.866" diameter) while maintaining the same capacitance and voltage rating. The SLPX102M160E3P3 and 380LQ102M180K012 retain the larger diameter (1.181") similar to the original part. PCB layout constraints determine which physical form factor is acceptable.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference between the 380LX and SLPX series?

A: Both are Cornell Dubilier Electronics aluminum electrolytic capacitor series with identical electrical specifications for the 1000 µF 100 V rating. The primary differences are physical dimensions and packaging. The 380LX series uses a larger diameter can, while the SLPX series uses a more compact design.

Q: Which substitute part offers the best inventory availability?

A: The SLPX102M100A3P3 provides the highest inventory level at 17457 Pcs, followed by the 380LX102M100H022 at 4133 Pcs. Both are suitable for immediate procurement.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes, provided all parts meet the circuit's voltage and capacitance requirements. However, using identical part numbers throughout a design is recommended for consistency and simplified inventory management.
