Substitute Part Grouping Explanation

Substitution eligibility for the SLPX271M350C5P3 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 270 µF
• Voltage Rating: 350 V
• Tolerance: ±20%
• Lead Spacing: 0.394" (10.00 mm)
• Case Diameter: 0.984" (25.00 mm)
• Height - Seated (Max): 1.457" (37.00 mm)
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Polarization: Polar

Allowable Variations:

• Operating Temperature Range: May extend beyond -25°C ~ 85°C
• Lifetime @ Temperature: May exceed 3000 Hrs @ 85°C
• ESR (Equivalent Series Resistance): Specification not required for substitution
• Ripple Current: May vary within application requirements

Substitute parts are classified into two categories:

Upgrade Substitutes: Parts with extended operating temperature range (up to 105°C) and improved thermal lifetime ratings (3000 Hrs @ 105°C), providing enhanced reliability in elevated temperature environments.

Parametric Equivalents: Parts with identical thermal and electrical specifications matching the original part's performance envelope.

Parameter Comparison

Engineering Selection Recommendations

For Standard Operating Conditions (-25°C to 85°C):

The LLS2V271MELA (Nichicon) provides parametric equivalence to the SLPX271M350C5P3. Both parts maintain identical operating temperature ranges and thermal lifetime specifications (3000 Hrs @ 85°C). This substitute is suitable for direct replacement in applications where thermal performance requirements match the original design envelope. All parts maintain ROHS3 compliance and active production status.

For Extended Temperature Applications (Up to 105°C):

The LGN2V271MELA35 and LQS2V271MELA35 (both Nichicon) offer upgrade substitution with extended operating temperature capability to 105°C and improved thermal lifetime (3000 Hrs @ 105°C). These parts are appropriate for applications requiring enhanced thermal margin or operation in elevated ambient conditions. Both maintain identical mechanical footprints and electrical ratings while providing superior thermal performance.

Selection Criteria:

All substitute parts maintain mechanical and electrical compatibility through identical lead spacing (10.00 mm), case diameter (25.00 mm), height (37.00 mm), and package configuration (Radial, Can - Snap-In). Substitution is valid based on product status (all active), regulatory compliance (all ROHS3 compliant), and core electrical specifications (270 µF, 350 V, ±20% tolerance).

Frequently Asked Questions (FAQ)

Q: Can LGN2V271MELA35 or LQS2V271MELA35 be used as direct replacements for SLPX271M350C5P3?

A: Yes. Both Nichicon parts are direct mechanical and electrical substitutes. They share identical capacitance (270 µF), voltage rating (350 V), tolerance (±20%), lead spacing (10.00 mm), case diameter (25.00 mm), and height (37.00 mm). The extended operating temperature range (to 105°C) represents an upgrade feature, not a limitation.

Q: What is the difference between LGN2V271MELA35, LQS2V271MELA35, and LLS2V271MELA?

A: All three are Nichicon 270 µF, 350 V aluminum electrolytic capacitors in identical snap-in packages. LGN2V271MELA35 and LQS2V271MELA35 operate to 105°C with 3000 Hrs lifetime at that temperature. LLS2V271MELA operates to 85°C with 3000 Hrs lifetime at 85°C, matching the original SLPX271M350C5P3 thermal specification.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All substitute parts maintain identical mechanical specifications: lead spacing of 0.394" (10.00 mm), case diameter of 0.984" (25.00 mm), and seated height of 1.457" (37.00 mm). All use through-hole mounting with radial, can snap-in package configuration. PCB layout and mounting hardware require no modification.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The SLPX271M350C5P3 and all three substitute parts (LGN2V271MELA35, LQS2V271MELA35, LLS2V271MELA) are ROHS3 compliant. All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q: Which substitute should be selected for applications operating above 85°C?

A: For applications requiring operation above 85°C up to 105°C, select either LGN2V271MELA35 or LQS2V271MELA35. Both provide extended operating temperature range and improved thermal lifetime (3000 Hrs @ 105°C). For applications remaining within the -25°C to 85°C envelope, LLS2V271MELA provides parametric equivalence to the original part.

Q: Are there differences in ripple current handling between these parts?

A: Ripple current specifications vary among the parts. The SLPX271M350C5P3 and LLS2V271MELA both support 1.73 A @ 120 Hz. The LGN2V271MELA35 and LQS2V271MELA35 support 1.1 A @ 120 Hz. Application-specific ripple current requirements must be verified against the actual circuit demands to ensure appropriate part selection.
