SLP271M315A4P3 Equivalent & Substitute Parts

Part Overview

The SLP271M315A4P3 is a 270 µF, 315 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and extended operational life. The part operates across a temperature range of -25°C to 105°C with a rated lifetime of 3000 hours at 105°C.

Substitute parts are identified when equivalent capacitance, tolerance, package configuration, and mounting type align with the original specification, while voltage rating and operational characteristics may differ within acceptable engineering parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the SLP271M315A4P3 is determined by the following criteria:

Primary Matching Parameters (Mandatory):

• Capacitance: 270 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.866" Dia (22.00mm) (exact match required)
• Height - Seated (Max): 1.850" (47.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Secondary Parameters (Allowable Variation):

• Voltage - Rated: Equal to or greater than 315 V
• Operating Temperature: Must encompass -25°C to 105°C minimum
• Lifetime @ Temp.: Equal to or greater than 3000 Hrs @ 105°C

The substitute part 400VXH270MEFCSN22X45 meets all primary matching parameters and exceeds secondary parameter requirements with a higher voltage rating (400 V) and extended lifetime (5000 Hrs @ 105°C).

Engineering Selection Recommendations

SLP271M315A4P3 (Cornell Dubilier Electronics):

• Primary selection for applications requiring exact voltage specification of 315 V
• Active product status with established supply chain
• ROHS3 compliant and REACH unaffected
• Suitable for general-purpose applications with standard operational requirements

400VXH270MEFCSN22X45 (Rubycon):

• Direct substitute with enhanced performance characteristics
• Higher voltage rating (400 V) provides additional safety margin in circuits operating at or below 315 V
• Extended lifetime rating (5000 Hrs @ 105°C vs. 3000 Hrs @ 105°C) supports applications requiring extended operational durability
• Increased ripple current capacity at both low and high frequencies
• Active product status with ROHS3 compliance and REACH unaffected designation
• Identical mechanical footprint and electrical interface ensure direct board-level compatibility

Both parts maintain identical physical dimensions, lead spacing, and mounting configuration, enabling direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the 400VXH270MEFCSN22X45 be used as a direct replacement for the SLP271M315A4P3?

A: Yes. The substitute part matches all primary mechanical and electrical parameters including capacitance (270 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00mm), physical dimensions (22.00mm diameter, 47.00mm height), and mounting type (Through Hole). The higher voltage rating (400 V) and extended lifetime (5000 Hrs @ 105°C) represent performance enhancements rather than incompatibilities.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (315 V vs. 400 V), lifetime at 105°C (3000 Hrs vs. 5000 Hrs), and ripple current capacity. The Rubycon part provides higher voltage headroom and extended operational life. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Both are classified as Active product status.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00mm), diameter (0.866" / 22.00mm), and maximum seated height (1.850" / 47.00mm). No PCB modifications are required.

Q: What is the significance of the higher voltage rating on the substitute part?

A: A 400 V rated capacitor can be used in circuits designed for 315 V operation. The higher voltage rating provides additional electrical stress margin and does not negatively impact circuit performance. This is a standard engineering practice for component substitution.

Q: Are there any ripple current considerations for substitution?

A: The substitute part provides higher ripple current capacity at both 120 Hz (1.56 A vs. 1.16 A) and 20 kHz / 10 kHz frequencies. This represents an enhancement and does not create compatibility issues in applications designed for the original part's ripple current specifications.
