SLPX151M350C1P3 Equivalent & Substitute Parts

Part Overview

The SLPX151M350C1P3 is a 150 µF, 350 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is rated for general-purpose applications with an operating temperature range of -25°C to 85°C and a lifetime specification of 3000 hours at 85°C. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification.

Substitute parts are necessary when the original SLPX151M350C1P3 becomes unavailable, when higher voltage ratings or extended lifetime specifications are required for system reliability, or when alternative manufacturer sourcing is needed to optimize supply chain resilience.

• Lifetime @ Temperature: Substitutes offer 3000 to 8000 hours at elevated temperatures, improving reliability over the original 3000 hours @ 85°C

Compliance Maintained: All substitute parts retain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full regulatory compliance (RoHS3 and REACH unaffected), ensuring continuity of design certification and supply chain qualification.

For applications requiring enhanced voltage margin: The 400 V rated substitutes (400MXG150MEFCSN25X25, 400VXH150MEFCSN25X25, B43508B9157M000, B43634B9157M000, and LGX2G151MELA25) provide 50 V additional voltage headroom above the original 350 V specification, suitable for circuits with transient voltage conditions or future design upgrades.

For applications requiring extended operational lifetime: The 400VXH150MEFCSN25X25 (Rubycon, 5000 Hrs @ 105°C), B43634B9157M000 (EPCOS - TDK, 8000 Hrs @ 85°C), and LGX2G151MELA25 (Nichicon, 5000 Hrs @ 105°C) offer superior lifetime ratings compared to the original 3000 hours @ 85°C specification.

For applications requiring extended temperature operation: The B43508B9157M000 (EPCOS - TDK) extends the lower operating temperature limit to -40°C, while Rubycon and Nichicon substitutes extend the upper limit to 105°C, accommodating wider environmental conditions.

For applications with ESR-sensitive circuits: The B43634B9157M000 (720 mOhm @ 100 Hz) and B43508B9157M000 (820 mOhm @ 100 Hz) provide lower ESR values compared to the original SLPX151M350C1P3 (1.33 Ohm @ 120 Hz), beneficial for high-frequency ripple current filtering.

Frequently Asked Questions (FAQ)

Q: Can I use a 400 V rated substitute in place of the 350 V SLPX151M350C1P3?

A: Yes. All listed substitutes rated at 400 V are electrically compatible. The higher voltage rating provides additional safety margin and does not affect circuit operation. The capacitance, tolerance, physical dimensions, and mounting characteristics remain identical.

Q: Are the physical dimensions identical across all substitute parts?

A: Yes. All substitute parts maintain the same radial, can snap-in package with 0.984" diameter, 1.063" maximum seated height, and 0.394" lead spacing. Direct mechanical substitution is possible without PCB layout modification.

Q: What is the difference between the Rubycon MXG and VXH series substitutes?

A: Both Rubycon substitutes (400MXG150MEFCSN25X25 and 400VXH150MEFCSN25X25) share identical electrical specifications and physical dimensions. The VXH series offers extended lifetime (5000 Hrs @ 105°C) compared to the MXG series (3000 Hrs @ 105°C).

Q: Do all substitutes maintain RoHS3 and REACH compliance?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original SLPX151M350C1P3.

Q: Which substitute offers the lowest ESR?

A: The B43634B9157M000 (EPCOS - TDK) provides the lowest ESR at 720 mOhm @ 100 Hz, followed by B43508B9157M000 at 820 mOhm @ 100 Hz. The original SLPX151M350C1P3 has an ESR of 1.33 Ohm @ 120 Hz.

Q: Can I use these substitutes in high-temperature applications?

A: Yes. The Rubycon VXH series (400VXH150MEFCSN25X25), EPCOS B43508B9157M000, and Nichicon LGX2G151MELA25 all support operating temperatures up to 105°C, exceeding the original specification of 85°C maximum.

Q: Are there inventory considerations for these substitutes?

A: All substitute parts are listed as Active with available inventory. Rubycon 400MXG150MEFCSN25X25 has the highest inventory level (1,000,200 pcs), while EPCOS B43508B9157M000 has the lowest (1,609 pcs).

Q: What is the difference between the two EPCOS substitutes?

A: Both EPCOS substitutes (B43508B9157M000 and B43634B9157M000) are 150 µF, 400 V, snap-in packages. The B43634B9157M000 offers extended lifetime (8000 Hrs @ 85°C vs. 3000 Hrs @ 105°C) and lower ESR (720 mOhm vs. 820 mOhm). The B43508B9157M000 supports a wider temperature range (-40°C to 105°C vs. -25°C to 85°C).
