SLP153M016C5P3 Equivalent & Substitute Parts

Part Overview

The SLP153M016C5P3 is a 15000 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is Active status and widely used in general-purpose applications requiring high capacitance at moderate voltage ratings. Substitute parts are necessary when primary stock availability is limited, when design optimization for specific electrical parameters is required, or when alternative form factors better suit mechanical constraints in the target application.

Substitute Part Grouping Explanation

Substitute parts for the SLP153M016C5P3 are grouped by substitution type based on the following critical electrical and mechanical parameters:

Direct Equivalents (Same Electrical Ratings): Parts with identical capacitance (15000 µF), voltage rating (16 V), and tolerance (±20%) that maintain compatibility with the through-hole, snap-in mounting interface are classified as direct substitutes. These parts support drop-in replacement without circuit design modification.

Key Substitution Criteria:

Capacitance tolerance: ±20% (fixed)
Voltage rating: 16 V minimum
Polarization: Polar
Operating temperature range: -40°C ~ 105°C
Lifetime: 3000 Hrs @ 105°C
Mounting interface: Through-hole, radial snap-in configuration
Lead spacing: 0.394" (10.00 mm)
RoHS3 compliance and REACH unaffected status required

Engineering Selection Recommendations

381LX153M016J032 and 381LX153M016K022 are direct functional equivalents with Active product status and full RoHS3/REACH compliance. Both maintain the 15000 µF capacitance and 16 V rating. Selection between these two should be based on available PCB space: the 381LX153M016J032 offers reduced height (37.00 mm vs. 32.00 mm seated) with similar form factor, while the 381LX153M016K022 provides a wider diameter (30.00 mm) with reduced height, suitable for designs with horizontal space constraints. The 381LX153M016K022 has superior inventory availability at 1898 units.

SLP153M025C4P3 operates at 25 V, providing overvoltage margin in 16 V applications and lower ESR (40 mOhm vs. 44 mOhm). This part is suitable when enhanced voltage margin or improved ripple current handling is required, though it occupies greater height (45.00 mm). This part maintains Active status and full compliance certifications.

All substitute candidates are manufactured by Cornell Dubilier Electronics and carry ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can 381LX153M016J032 or 381LX153M016K022 be used as direct drop-in replacements for SLP153M016C5P3? A: Yes, both parts maintain identical capacitance (15000 µF), voltage rating (16 V), tolerance (±20%), and mounting interface (through-hole radial snap-in). Mechanical compatibility requires verification of available PCB height: 381LX153M016J032 adds 2 mm additional height, while 381LX153M016K022 reduces height by 3 mm but increases diameter by 5 mm.

Q: What is the difference between the three 16 V substitute options? A: All three maintain the same electrical rating. The differences are mechanical: SLP153M016C5P3 and 381LX153M016J032 share the same 25 mm diameter with differing heights; 381LX153M016K022 uses a 30 mm diameter with reduced height of 32 mm. ESR specifications differ slightly between the SLP series (44 mOhm) and 381LX series (not specified in data).

Q: When should SLP153M025C4P3 (25 V) be selected over 16 V alternatives? A: The 25 V part provides overvoltage protection margin and delivers lower ESR (40 mOhm), resulting in improved ripple current handling and reduced heat dissipation. Use this part when the circuit operates near the 16 V maximum or when lower impedance is beneficial. The increased height (45 mm) must be accommodated in the mechanical design.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all listed parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the significance of snap-in mounting for these capacitors? A: Snap-in packaging uses mechanical snap features on the can body for rapid, tool-free PCB mounting without soldering leads. All parts in this comparison use this mounting interface, ensuring mechanical compatibility. Lead spacing (10 mm) is consistent across all options.
