Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLP271M350A9P3 are selected based on electrical and mechanical compatibility. All substitute parts maintain identical or higher electrical specifications:

Key Substitution Parameters:

• Capacitance: 270 µF (exact match required)
• Tolerance: ±20% (consistent across all parts)
• Voltage Rating: Equal to or greater than 350 V (400 V and 450 V substitutes provide voltage margin)
• Package Type: Radial, Can - Snap-In (mechanical interchangeability)
• Lead Spacing: 0.394" (10.00 mm) (footprint compatibility)
• Physical Dimensions: Diameter 0.866" (22.00 mm), Height within 2.047" to 2.067" (mechanical fit)
• Mounting: Through Hole (identical connection method)
• Polarization: Polar (same polarity requirement)

All substitute parts listed are active products with RoHS3 or full RoHS compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

SLP271M350A9P3 (Cornell Dubilier Electronics) Select this part when the original equipment specification requires the 350 V rated voltage with the SLP0712TE series characteristics and CDE sourcing is preferred. This part is active in product status with ROHS3 compliance.

B43508A9277M000 (EPCOS - TDK Electronics) This part provides a direct voltage upgrade to 400 V while maintaining identical mechanical compatibility and capacitance. The lower ESR of 460 mOhm @ 100 Hz compared to the original 1.229 Ohm @ 120 Hz reduces thermal dissipation. Operating temperature range extends to -40°C, providing broader environmental coverage. ROHS3 compliant and active in product status.

ELHS451VSN271MP50S (Chemi-Con) This part offers the highest voltage rating at 450 V with extended lifetime rating of 5000 Hrs @ 105°C (compared to 3000 Hrs for the original). Operating temperature range extends to -40°C. Mechanical compatibility is maintained with a maximum seated height of 2.067" (52.50 mm), which is within typical board clearance tolerances for snap-in capacitors. RoHS compliant and active in product status.

LGX2G271MELZ50 (Nichicon) This part matches the original operating temperature range of -25°C to 105°C while providing a voltage upgrade to 400 V. The 5000 Hrs @ 105°C lifetime rating provides extended reliability. Mechanical dimensions are identical to the original part. ROHS3 compliant and active in product status.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the SLP271M350A9P3? A: All listed parts are direct mechanical and electrical substitutes. They share identical capacitance, tolerance, lead spacing, diameter, and through-hole mounting configuration. Physical dimensions (height within 0.02" / 0.5 mm variation) are compatible with standard board layouts for snap-in capacitors.

Q: What is the significance of the higher voltage ratings on the substitute parts? A: The substitute parts rated at 400 V and 450 V provide voltage margin above the original 350 V specification. This allows operation at the same 350 V circuit voltage with additional design headroom for transient conditions and improved long-term reliability.

Q: How do the different lifetime ratings affect circuit design? A: The original part specifies 3000 Hrs @ 105°C, while ELHS451VSN271MP50S and LGX2G271MELZ50 specify 5000 Hrs @ 105°C. The extended lifetime rating indicates longer service life under elevated temperature conditions, suitable for applications with prolonged thermal stress or extended equipment operational life requirements.

Q: Are there compatibility concerns with the 2.067" height of the ELHS451VSN271MP50S? A: The ELHS451VSN271MP50S has a maximum seated height of 2.067" compared to 2.047" for the original part, a difference of 0.02" (0.5 mm). This minimal variation is within standard design tolerances for through-hole snap-in capacitor packages and does not affect mechanical interchangeability for typical board layouts.

Q: Do all substitute parts meet the same regulatory standards? A: All substitute parts are RoHS compliant (ROHS3 or full RoHS), REACH unaffected, and classified as EAR99 for export control purposes. All are active products with no obsolescence risk indicated.

Q: Can these parts be used interchangeably in the same circuit? A: The parts are electrically and mechanically compatible within the functional parameters specified. Circuit performance may vary slightly due to differences in ESR characteristics and rated lifetime, which do not affect substitutability for general-purpose power supply filtering applications.
