• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 0.984" Dia × 1.063" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Compliance Parameters:

• RoHS3 Compliant status
• REACH Unaffected status

Both identified substitute parts meet all critical matching parameters and compliance requirements, confirming direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

B43644B5107M000 (EPCOS - TDK Electronics): This substitute part maintains all critical electrical and mechanical parameters required for direct replacement. The part is Active status with ROHS3 compliance and REACH unaffected designation. The extended operating temperature range (-40°C ~ 105°C) and extended lifetime rating (5000 Hrs @ 105°C) provide enhanced thermal performance characteristics compared to the main part.

LGN2W101MELA25 (Nichicon): This substitute part meets all critical electrical and mechanical parameters for direct replacement. The part is Active status with ROHS3 compliance and REACH unaffected designation. The extended operating temperature range (-25°C ~ 105°C) and extended lifetime rating (3000 Hrs @ 105°C) provide enhanced thermal performance characteristics compared to the main part.

Both substitute parts are suitable for applications where the SLPX101M450C1P3 is specified, provided that circuit design does not depend on the specific ESR or ripple current characteristics of the original part.

Frequently Asked Questions (FAQ)

Q: Can B43644B5107M000 or LGN2W101MELA25 be used as direct replacements for SLPX101M450C1P3?

A: Yes. Both parts match the critical parameters: 100 µF capacitance, 450 V voltage rating, ±20% tolerance, radial snap-in package, 10.00mm lead spacing, 25.00mm diameter, 27.00mm maximum height, through-hole mounting, and polar polarization. All three parts are Active status, ROHS3 compliant, and REACH unaffected.

Q: What are the key differences between the three parts?

A: The main differences are ESR values, lifetime ratings, and operating temperature ranges. SLPX101M450C1P3 operates -25°C ~ 85°C with 3000 Hrs @ 85°C lifetime. B43644B5107M000 operates -40°C ~ 105°C with 5000 Hrs @ 105°C lifetime and lower ESR (980 mOhm @ 100Hz). LGN2W101MELA25 operates -25°C ~ 105°C with 3000 Hrs @ 105°C lifetime.

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

A: No. All three parts share identical mechanical specifications: 0.984" diameter, 1.063" maximum seated height, 0.394" lead spacing, and radial snap-in package configuration. PCB footprints and mounting hardware are directly compatible.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part should be selected for high-temperature applications?

A: Both substitute parts support higher operating temperatures than the main part. B43644B5107M000 extends to -40°C ~ 105°C with 5000 Hrs @ 105°C rating. LGN2W101MELA25 extends to -25°C ~ 105°C with 3000 Hrs @ 105°C rating. Selection depends on specific temperature and lifetime requirements of the application.
