SLP103M050E9P3 Equivalent & Substitute Parts
Part Overview
The SLP103M050E9P3 is a 10000 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active and is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when alternative packaging configurations better suit specific assembly requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
Substitution eligibility for aluminum electrolytic capacitors is determined by strict equivalence across the following parameters:
Critical Electrical Parameters (Must Match Exactly):
- Capacitance: 10000 µF
- Voltage Rating: 50 V
- Tolerance: ±20%
- Operating Temperature Range: -40°C ~ 105°C
- Lifetime @ Temperature: 3000 Hrs @ 105°C
- Polarization: Polar
Critical Mechanical Parameters (Must Match Exactly):
- Mounting Type: Through Hole
- Package / Case: Radial, Can - Snap-In
- Lead Spacing: 0.394" (10.00mm)
Acceptable Variations:
- Physical dimensions (diameter and height) may vary within the snap-in footprint constraint
- Packaging format (Bulk vs. Tray) does not affect electrical or mechanical compatibility
- ESR and ripple current specifications may differ provided the substitute meets or exceeds performance requirements
Both substitute parts (381LX103M050A042 and 381LX103M050K052) satisfy all critical electrical and mechanical parameters and are therefore direct substitutes for the SLP103M050E9P3.

Engineering Selection Recommendations
All three parts are Active products manufactured by Cornell Dubilier Electronics and maintain full compliance with RoHS3 and REACH regulations. Selection between the main part and substitutes is based on physical space constraints and packaging availability:
SLP103M050E9P3 (Primary Part): Use when the original specification calls for 30mm diameter and 50mm height in Bulk packaging format.
381LX103M050A042 (Substitute): Use when space constraints permit a larger diameter (35mm) but require reduced height (42mm). Available in Tray packaging. This configuration provides the most compact vertical profile.
381LX103M050K052 (Substitute): Use when the original specification calls for 30mm diameter but can accommodate increased height (52mm). Available in Bulk packaging. This configuration maintains the same footprint diameter as the primary part.
All three parts are electrically and mechanically interchangeable within their respective physical envelope constraints. Selection should be based on available board space and assembly line packaging requirements.
Frequently Asked Questions (FAQ)
Q: Can 381LX103M050A042 be used as a direct replacement for SLP103M050E9P3?
A: Yes, provided the printed circuit board layout accommodates the larger diameter (35mm vs. 30mm) and reduced height (42mm vs. 50mm). All electrical parameters and lead spacing are identical.
Q: What is the difference between Bulk and Tray packaging?
A: Packaging format affects handling and assembly processes but does not impact electrical or mechanical performance. Bulk packaging is suitable for manual assembly or small-volume production. Tray packaging is optimized for automated pick-and-place equipment.
Q: Are there any performance differences between the three parts?
A: All three parts meet the same electrical specifications for capacitance, voltage rating, tolerance, operating temperature, and lifetime. Physical dimensions vary to accommodate different board layouts. ESR and ripple current specifications are not provided for the 381LX series parts but do not affect substitution eligibility.
Q: Can these parts be used interchangeably in existing designs?
A: Interchangeability depends on physical space availability on the printed circuit board. The lead spacing (10mm) is identical across all three parts, ensuring compatibility with existing through-hole footprints. Verify that the board layout accommodates the specific diameter and height of the selected substitute.
Q: What compliance certifications apply to all substitute parts?
A: All three parts are RoHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.
