Engineering Selection Recommendations

B43501F2188M60 (Primary Selection)

The B43501F2188M60 is the recommended choice for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. Full ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current manufacturing standards.

B43540A2188M000 (Replacement/Legacy Support)

The B43540A2188M000 is suitable for replacement applications in existing designs where the B43501F2188M60 is unavailable. Although designated "Not For New Designs," this part provides full electrical and mechanical compatibility. The substitute exhibits superior performance characteristics with lower ESR (50 mOhm vs. 55 mOhm), higher ripple current capability (5.3 A vs. 4.75 A), and reduced impedance (65 mOhms vs. 75 mOhms). Both parts maintain identical compliance certifications and thermal ratings.

Frequently Asked Questions (FAQ)

Q: Can B43540A2188M000 be used as a direct replacement for B43501F2188M60?

A: Yes. Both parts share identical capacitance (1800 µF), voltage rating (200 V), tolerance (±20%), package configuration (Radial, Can - Snap-In), lead spacing (10.00 mm), and physical dimensions (35.00 mm diameter, 47.00 mm height). The B43540A2188M000 exhibits superior electrical characteristics with lower ESR and higher ripple current rating.

Q: Why is B43540A2188M000 marked "Not For New Designs"?

A: This designation indicates the part is in legacy production phase. While fully functional and compliant, EPCOS - TDK Electronics recommends the B43501F2188M60 for new design implementations to ensure extended availability and supply continuity.

Q: Are there any performance differences between these parts?

A: The B43540A2188M000 demonstrates improved performance metrics. ESR is 50 mOhm compared to 55 mOhm, ripple current capability is 5.3 A versus 4.75 A, and impedance is 65 mOhms versus 75 mOhms. These differences represent enhancements that do not compromise compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the B43501F2188M60 and B43540A2188M000 are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and safety regulations.

Q: What is the lead spacing significance for PCB design?

A: Both parts feature 10.00 mm lead spacing, ensuring identical PCB footprint compatibility. No layout modifications are required when substituting between these parts.
