• Diameter: 25.00 mm (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)

Identified Substitutes:

1. SLPX102M200C4P3 (Cornell Dubilier Electronics): Same-series upgrade with 200 V rating. Maintains identical capacitance, tolerance, ESR, lifetime, lead spacing, and diameter. Height increases from 40 mm to 45 mm. Suitable for applications requiring higher voltage margin within the same manufacturer platform.

2. LLS2D102MELA (Nichicon): Cross-manufacturer substitute with 200 V rating. Maintains identical capacitance, tolerance, lifetime, lead spacing, and diameter. Height matches original at 40 mm. ESR specification not provided in data. Suitable for applications where manufacturer diversity or specific Nichicon platform requirements apply.

Parameter Comparison

Engineering Selection Recommendations

SLPX102M200C4P3 Selection Criteria:

• Choose this substitute when higher voltage margin (200 V vs. 180 V) is required within the same CDE SLPX series platform
• Acceptable for applications where PCB height tolerance permits 45 mm maximum seated height (5 mm increase from original)
• Maintains identical electrical performance (ESR, lifetime, ripple current capability at 120 Hz)
• All regulatory compliance certifications (ROHS3, REACH) are equivalent to the original part
• Active product status ensures continued availability and supply chain stability

LLS2D102MELA Selection Criteria:

• Choose this substitute when cross-manufacturer sourcing is required or Nichicon platform standardization is specified
• Maintains original 40 mm seated height, eliminating height-related PCB layout concerns
• Provides 200 V voltage rating with equivalent capacitance and tolerance specifications
• All regulatory compliance certifications (ROHS3, REACH) are equivalent to the original part
• Active product status ensures continued availability
• ESR specification is not provided; verify ripple current performance at 50 kHz aligns with circuit requirements

General Substitution Constraints:

• All substitutes maintain identical lead spacing (10.00 mm) and diameter (25.00 mm) for direct PCB footprint compatibility
• All substitutes are through-hole radial snap-in packages with identical mounting characteristics
• Voltage rating upgrades (180 V to 200 V) are electrically compatible in applications designed for 180 V operation
• Operating temperature range remains -40°C to 85°C across all options

Frequently Asked Questions (FAQ)

Q: Can SLPX102M200C4P3 be used as a direct replacement for SLPX102M180C7P3?

A: Yes, with one mechanical consideration. The SLPX102M200C4P3 is electrically compatible and maintains all critical parameters (capacitance, tolerance, ESR, lifetime, lead spacing, diameter). The seated height increases from 40 mm to 45 mm. Verify PCB clearance and component placement constraints before substitution.

Q: What is the primary difference between SLPX102M200C4P3 and LLS2D102MELA?

A: Both are 1000 µF, 200 V substitutes with identical lead spacing and diameter. The key differences are: (1) Manufacturer—CDE vs. Nichicon; (2) Seated height—45 mm vs. 40 mm; (3) ESR specification—199 mOhm provided for CDE, not specified for Nichicon; (4) High-frequency ripple current rating—4.82 A @ 20 kHz vs. 4.92 A @ 50 kHz. Select based on manufacturer preference, height constraints, and ripple current frequency requirements.

Q: Is the voltage upgrade from 180 V to 200 V safe in my application?

A: Yes. A higher voltage rating provides additional safety margin. If your circuit operates at 180 V or below, substituting a 200 V rated capacitor is electrically safe and does not degrade performance. The capacitance, tolerance, and ESR remain unchanged.

Q: Will the 5 mm height difference of SLPX102M200C4P3 affect my PCB layout?

A: This depends on your specific PCB design. The SLPX102M200C4P3 has a maximum seated height of 45 mm compared to 40 mm for the original. Verify that your PCB layout, enclosure, or component placement constraints accommodate this increase. If height is critical, select LLS2D102MELA, which maintains the original 40 mm height.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. SLPX102M180C7P3, SLPX102M200C4P3, and LLS2D102MELA are all ROHS3 Compliant and REACH Unaffected. All three meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What does the ±20% tolerance mean for capacitance?

A: The ±20% tolerance indicates that the actual capacitance value will be within 20% of the nominal 1000 µF specification. This means the capacitance will fall between 800 µF and 1200 µF. All three parts share this tolerance specification, ensuring equivalent performance in applications designed for this tolerance range.

Q: Can I use LLS2D102MELA if ESR specification is not provided?

A: The ESR specification is not provided in the available data for LLS2D102MELA. If your circuit design requires a specific ESR value for ripple current filtering or thermal performance, contact the manufacturer (Nichicon) to obtain this specification before substitution. The provided ripple current ratings (3.28 A @ 120 Hz, 4.92 A @ 50 kHz) indicate the part is designed for similar applications.

Q: Are the lead spacing and mounting footprint identical across all three parts?

A: Yes. All three parts have identical lead spacing (10.00 mm), diameter (25.00 mm), and mounting type (through-hole radial snap-in). PCB footprints are directly compatible. The only mechanical difference is seated height: 40 mm for SLPX102M180C7P3 and LLS2D102MELA, and 45 mm for SLPX102M200C4P3.
