SLP151M315C1P3 Aluminum Electrolytic Capacitor Equivalent & Substitute Parts

Part Overview

The SLP151M315C1P3 is a 150 µF, 315 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, snap-in configuration. This component is Active product status and suitable for general-purpose applications requiring voltage support up to 315 V. Substitute parts are necessary when seeking upgraded voltage ratings (400 V), extended operational lifetime, improved thermal performance, or enhanced availability across multiple manufacturer sources while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts maintain direct electrical compatibility with the SLP151M315C1P3 through the following critical parameters:

Invariant Parameters (Must Match for Substitution):

• Capacitance: 150 µF (all substitutes)
• Tolerance: ±20% (all substitutes)
• Polarization: Polar (all substitutes)
• Lead Spacing: 0.394" (10.00mm) (all substitutes)
• Size / Dimension: 0.984" Dia (25.00mm) (all substitutes)
• Height - Seated (Max): 1.063" (27.00mm) (all substitutes)
• Mounting Type: Through Hole (all substitutes)
• Package / Case: Radial, Can - Snap-In (all substitutes)

Variable Parameters (Substitutes Exceed Original Specifications):

• Voltage - Rated: Substitutes rated at 400 V (exceeds original 315 V specification)
• Lifetime @ Temperature: Substitutes range from 3000 to 5000 Hrs @ 105°C (equal or exceeds original 3000 Hrs)
• Operating Temperature Range: Substitutes maintain -25°C ~ 105°C or extend to -40°C ~ 105°C
• RoHS Status: All substitutes are ROHS3 Compliant
• Compliance Certifications: All substitutes maintain REACH Unaffected and EAR99 ECCN status

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts meet Active product status and maintain full ROHS3, REACH Unaffected, and EAR99 compliance with the original SLP151M315C1P3.

400MXG150MEFCSN25X25 (Rubycon MXG Series): Suitable for applications requiring 400 V rated voltage with standard 3000-hour lifetime at 105°C. This part provides improved voltage margin over the original specification.

400VXH150MEFCSN25X25 (Rubycon VXH Series): Appropriate for applications demanding extended operational lifetime with 5000-hour rating at 105°C and 400 V voltage support. This upgrade addresses thermal stability requirements across extended operating periods.

B43508B9157M000 (EPCOS - TDK B43508 Series): Applicable for applications requiring lower operating temperature tolerance extending to -40°C with 400 V voltage rating. The specified ESR value of 820mOhm @ 100Hz provides measurable impedance data for circuit performance analysis.

LGX2G151MELA25 (Nichicon LGX Series): Suitable for applications requiring 5000-hour lifetime rating at 105°C with 400 V voltage support. Ripple current specification at 50 kHz indicates suitability for high-frequency circuit applications.

Frequently Asked Questions (FAQ)

Q: Can substitute parts with 400 V rating replace a 315 V specification? A: Yes. All substitute parts are rated at 400 V, exceeding the original 315 V requirement. A higher-rated voltage capacitor operates within lower stress conditions in a 315 V application and maintains electrical compatibility.

Q: Are the physical dimensions identical across all parts? A: Yes. All substitute parts maintain identical lead spacing (10.00mm), diameter (25.00mm), and seated height (27.00mm), ensuring direct mechanical compatibility in Through Hole mounting applications.

Q: What is the difference between 3000-hour and 5000-hour lifetime ratings? A: Lifetime ratings specify the expected operational duration at 105°C. The 5000-hour substitutes (400VXH150MEFCSN25X25 and LGX2G151MELA25) provide extended reliability for applications with longer service requirements or higher thermal stress conditions.

Q: Why are some ESR values not specified for substitute parts? A: ESR data is provided only when measured and documented by the manufacturer. Parts without specified ESR values are still suitable for general-purpose applications. EPCOS part B43508B9157M000 includes ESR specification at 820mOhm @ 100Hz for applications requiring this parameter.

Q: Does RoHS3 compliance apply to all substitutes? A: Yes. All substitute parts maintain ROHS3 compliance status, ensuring compatibility with regulatory requirements equivalent to the original SLP151M315C1P3.

Q: Are operating temperature ranges different between substitutes? A: Most substitutes maintain -25°C ~ 105°C range. The EPCOS part (B43508B9157M000) extends the lower limit to -40°C, providing enhanced performance in colder operating environments.
