SLP151M385E1P3 Equivalent & Substitute Parts

Part Overview

The SLP151M385E1P3 is a 150 µF, 385 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 a 3000-hour lifetime at 105°C and an operating temperature range of -25°C to 105°C. The part is Active in product status and ROHS3 compliant.

Substitute parts are necessary when the original SLP151M385E1P3 becomes unavailable, when higher voltage ratings or extended operational lifetimes are required, or when alternative manufacturers' components meet or exceed the electrical and mechanical specifications of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SLP151M385E1P3 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match or Exceed):

• Capacitance: 150 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 385 V (higher ratings are acceptable)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 1.181" Dia (30.00mm) and 1.063" Height (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Parameters That May Vary:

• Lifetime @ Temperature: May be equal to or exceed 3000 Hrs @ 105°C
• ESR (Equivalent Series Resistance): Not required to match
• Ripple Current: Not required to match
• Manufacturer: May differ

All substitute parts listed meet or exceed these criteria and are suitable for direct replacement in applications where the SLP151M385E1P3 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active in product status and ROHS3 compliant, meeting regulatory requirements equivalent to the original SLP151M385E1P3.

Voltage Rating Consideration: All substitute parts are rated at 450 V, which exceeds the original 385 V specification. This higher voltage rating provides additional design margin and is electrically compatible with circuits designed for 385 V operation.

Lifetime Consideration: Substitute parts are available in two lifetime categories:

• 3000 Hrs @ 105°C: LGN2W151MELB25 and LQS2W151MELB25 (equivalent to original)
• 5000 Hrs @ 105°C: 450VXG150MEFC30X25, 450VXG150MEFCSN30X25, and LGX2W151MELB25 (extended lifetime)

Manufacturer Options:

• Rubycon: 450VXG150MEFC30X25, 450VXG150MEFCSN30X25
• Nichicon: LGN2W151MELB25, LGX2W151MELB25, LQS2W151MELB25

All substitute parts maintain identical mechanical compatibility and electrical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can I use a 450 V rated capacitor in place of the 385 V SLP151M385E1P3?

A: Yes. A higher voltage rating is electrically compatible with circuits designed for lower voltage operation. The 450 V substitute parts provide additional voltage margin and are suitable for direct replacement.

Q: Are all substitute parts mechanically identical to the original?

A: Yes. All substitute parts share identical lead spacing (0.394" / 10.00mm), physical dimensions (1.181" diameter, 1.063" height), and package type (Radial, Can - Snap-In). They mount identically on through-hole PCB layouts.

Q: What is the difference between the 3000-hour and 5000-hour lifetime parts?

A: The lifetime rating indicates the expected operational duration at 105°C. Parts with 5000-hour ratings (450VXG150MEFC30X25, 450VXG150MEFCSN30X25, LGX2W151MELB25) provide extended service life compared to 3000-hour rated parts (LGN2W151MELB25, LQS2W151MELB25). Selection depends on application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original SLP151M385E1P3.

Q: Can I interchange substitute parts from different manufacturers?

A: Yes. All substitute parts meet identical electrical and mechanical specifications and are interchangeable within the same circuit application. Selection may be based on availability, lead time, or manufacturer preference.

Q: What is the capacitance tolerance for all parts?

A: All parts, including the original and all substitutes, are rated at ±20% capacitance tolerance. This tolerance applies uniformly across the entire product range.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -25°C to 105°C, matching the original SLP151M385E1P3 specification.
