LPW103M1EP30V-W Equivalent & Substitute Parts

Part Overview

The LPW103M1EP30V-W is a 10000 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the LPW series. This radial, can-style snap-in component is designed for general-purpose applications requiring high capacitance in a compact form factor. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The original specification includes 75 mOhm ESR at 120 Hz and a rated lifetime of 1000 hours at 85°C.

Substitute Part Grouping Explanation

Substitution of the LPW103M1EP30V-W is determined by strict electrical and mechanical compatibility criteria. All substitute parts must meet the following mandatory parameters:

Electrical Requirements:

Capacitance: 10000 µF (±20% tolerance acceptable)
Voltage Rating: 25 V minimum
Polarization: Polar (same as original)
Operating Temperature: -40°C to 85°C minimum range

Mechanical Requirements:

Lead Spacing: 0.394" (10.00 mm)
Mounting Type: Through Hole
Package Type: Radial, Can - Snap-In
Physical dimensions compatible with PCB layout constraints

Compliance Requirements:

RoHS3 Compliant
REACH Unaffected status

Substitute parts are classified into two categories: Direct Substitutes (electrically and mechanically equivalent with active product status) and Similar Parts (meet core parameters but may have dimensional or performance variations). ESR, ripple current ratings, and lifetime specifications vary among substitutes and must be evaluated against application requirements.

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

The following parts are classified as direct substitutes with active product status and full compliance certification:

SLPX103M025E1P3: Active status, ROHS3 compliant, 60 mOhm ESR, 3000-hour lifetime at 85°C. Diameter matches original (30 mm), height reduced to 25 mm. Suitable for space-constrained applications.
380LX103M025K012: Active status, ROHS3 compliant, 136 mOhm ESR, 3000-hour lifetime at 85°C. Maintains 30 mm diameter, height 27 mm. Higher ESR acceptable for general-purpose applications.
109LBB025M2DC: Active status, ROHS3 compliant, 49.736 mOhm ESR, 3000-hour lifetime at 85°C. Lowest ESR among direct substitutes. Diameter 30 mm, height 27 mm.

Similar Parts (Dimensional Variations):

The following parts meet electrical specifications but have dimensional variations requiring PCB layout verification:

380LX103M025H032: Reduced diameter (22 mm), increased height (37 mm). ESR 58 mOhm, 3000-hour lifetime.
380LX103M025J022: Diameter 25 mm, height 32 mm. ESR 58 mOhm, 3000-hour lifetime.

Frequently Asked Questions (FAQ)

Q: Can SLPX103M025E1P3 replace LPW103M1EP30V-W directly on the PCB?

A: SLPX103M025E1P3 meets all electrical requirements and maintains the 10 mm lead spacing. However, the height is reduced from 30 mm to 25 mm. Verify that the reduced height does not create clearance issues with adjacent components or enclosure constraints.

Q: What is the significance of ESR differences among substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The original LPW103M1EP30V-W has 75 mOhm ESR. Substitutes range from 49.736 mOhm to 136 mOhm. Lower ESR reduces heat and improves ripple current performance; higher ESR is acceptable for low-frequency, low-ripple applications. Verify application ripple current requirements against substitute specifications.

Q: Why do some substitutes have 3000-hour lifetimes instead of 1000 hours?

A: Extended lifetime ratings indicate improved capacitor design and materials. Parts with 3000-hour ratings at 85°C provide longer operational life and greater reliability margin. This is a performance improvement over the original 1000-hour specification.

Q: Is SLP103M025E3P3 suitable for high-temperature applications?

A: SLP103M025E3P3 is rated for 3000 hours at 105°C, compared to the original 1000 hours at 85°C. This part is suitable for applications requiring extended temperature operation. However, verify that the application's maximum operating temperature does not exceed 105°C.

Q: Can I use 380LX103M025H032 if my PCB has limited horizontal space?

A: Yes. 380LX103M025H032 has a reduced diameter of 22 mm (compared to 30 mm original), but increased height to 37 mm. This trade-off is suitable only if vertical space is available and horizontal space is constrained. Verify PCB layout compatibility before selection.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the original LPW103M1EP30V-W compliance status.

Q: What is the difference between CDE and Illinois Capacitor parts?

A: 109LBA025M2DC and 109LBB025M2DC are manufactured by Cornell Dubilier / Illinois Capacitor. Illinois Capacitor is a division of CDE. These parts maintain the same compliance standards and electrical specifications as other CDE products in this list.

Q: Can Chemi-Con ESMH250VSN103MR25S be used as a long-term replacement?

A: ESMH250VSN103MR25S is an active product from a different manufacturer (Chemi-Con) with equivalent electrical specifications. It is suitable for replacement applications. However, the 2000-hour lifetime at 85°C is shorter than CDE alternatives offering 3000 hours. Evaluate application lifetime requirements before selection.

Q: What should I verify before finalizing a substitute part selection?

A: Verify the following: (1) PCB layout compatibility with substitute dimensions; (2) application ripple current requirements against substitute ESR and ripple current ratings; (3) operating temperature range requirements; (4) lifetime requirements at operating temperature; (5) lead spacing and mounting hole compatibility; (6) clearance with adjacent components and enclosure.
