Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLPX392M080C4P3 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Capacitance: 3900 µF (exact match required)
• Voltage Rating: 80 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Variation Parameters:

• ESR @ 120Hz: Variation permitted within component performance envelope
• Ripple Current @ Low Frequency: Variation permitted within component performance envelope
• Ripple Current @ High Frequency: Variation permitted within component performance envelope
• Physical Dimensions (Diameter, Height): Variation permitted provided lead spacing and mounting compatibility remain unchanged
• MSL Rating: Variation permitted (Not Applicable to Unlimited)

Two substitute parts meet these criteria: 380LX392M080J452 (Direct Manufacturer Substitute) and SLPX392M080E5P3 (Similar Manufacturer Part).

Parameter Comparison

Engineering Selection Recommendations

SLPX392M080C4P3 (Primary Part)

The SLPX392M080C4P3 remains the primary specification. Active product status, ROHS3 compliance, and REACH unaffected designation confirm regulatory alignment. Current inventory of 701 pieces supports immediate procurement.

380LX392M080J452 (Direct Manufacturer Substitute)

The 380LX392M080J452 qualifies as a direct manufacturer substitute. All critical electrical parameters match the primary part: 3900 µF capacitance, 80 V rating, ±20% tolerance, 3000-hour lifetime at 85°C, and identical lead spacing. ESR is 80 mOhm at 120Hz, representing a 5.9% improvement over the primary part's 85 mOhm specification. Physical dimensions show a 2 mm height increase (47.00 mm vs. 45.00 mm) while maintaining the same 25.00 mm diameter. Active product status, ROHS3 compliance, and REACH unaffected status confirm regulatory equivalence. Inventory of 670 pieces is available. MSL rating is 1 (Unlimited), compared to Not Applicable for the primary part.

SLPX392M080E5P3 (Similar Manufacturer Part)

The SLPX392M080E5P3 qualifies as a similar manufacturer part within the same SLPX series. Electrical specifications are identical to the primary part: 3900 µF, 80 V, ±20% tolerance, 85 mOhm ESR at 120Hz, and 3000-hour lifetime at 85°C. Physical dimensions differ: diameter increases to 30.00 mm (5 mm larger) while height decreases to 35.00 mm (10 mm shorter). Lead spacing remains 10.00 mm. Ripple current at 20 kHz is marginally higher at 4.63 A versus 4.53 A. Active product status, ROHS3 compliance, and REACH unaffected designation confirm regulatory alignment. Highest inventory availability at 2209 pieces supports procurement flexibility.

Selection Basis:

All three parts maintain Active product status and ROHS3 compliance. Selection between them depends on physical space constraints within the application. The SLPX392M080E5P3 offers the most compact height profile (35.00 mm) with the largest diameter (30.00 mm). The 380LX392M080J452 provides the lowest ESR specification (80 mOhm) with minimal height increase. The primary SLPX392M080C4P3 maintains the original specification baseline.

Frequently Asked Questions (FAQ)

Q: Can SLPX392M080E5P3 be used as a direct replacement for SLPX392M080C4P3?

A: Yes. Both parts share identical electrical specifications: 3900 µF capacitance, 80 V rating, ±20% tolerance, 85 mOhm ESR at 120Hz, and 3000-hour lifetime at 85°C. Physical dimensions differ (diameter 30.00 mm vs. 25.00 mm; height 35.00 mm vs. 45.00 mm), but lead spacing remains 10.00 mm. Substitution is valid provided the application PCB layout accommodates the larger diameter and shorter height.

Q: What is the difference between 380LX392M080J452 and SLPX392M080C4P3?

A: The 380LX392M080J452 is from a different CDE series (380LX vs. SLPX) but maintains all critical electrical equivalence: 3900 µF, 80 V, ±20% tolerance, and 3000-hour lifetime at 85°C. The 380LX part features lower ESR (80 mOhm vs. 85 mOhm) and slightly higher height (47.00 mm vs. 45.00 mm). Both are ROHS3 compliant and REACH unaffected.

Q: Are all three parts interchangeable on the same PCB?

A: Electrical interchangeability is confirmed across all three parts. Physical interchangeability depends on PCB layout constraints. The SLPX392M080C4P3 and 380LX392M080J452 share identical 25.00 mm diameter but differ in height (45.00 mm vs. 47.00 mm). The SLPX392M080E5P3 has a larger diameter (30.00 mm) and shorter height (35.00 mm). Verify PCB footprint and clearance specifications before substitution.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. ECCN classification is EAR99 for all parts. HTSUS code 8532.22.0040 applies uniformly.

Q: Which part has the best ESR performance?

A: The 380LX392M080J452 has the lowest ESR at 80 mOhm @ 120Hz, compared to 85 mOhm for both SLPX parts. This represents a 5.9% improvement in equivalent series resistance.

Q: What is the inventory status for each part?

A: SLPX392M080C4P3: 701 pieces. 380LX392M080J452: 670 pieces. SLPX392M080E5P3: 2209 pieces. The SLPX392M080E5P3 offers the highest inventory availability.

Q: Can I use SLPX392M080E5P3 in a space-constrained application?

A: The SLPX392M080E5P3 provides the most compact height (35.00 mm) but requires a larger PCB footprint diameter (30.00 mm vs. 25.00 mm). Evaluate both vertical and horizontal space constraints before selection.
