Engineering Selection Recommendations

All three parts—861010786021, SLPX682M063H3P3, and B41231C8688M000—carry Active product status and maintain ROHS3 compliance with REACH Unaffected designation. Selection among these alternatives is determined by application-specific requirements and inventory availability rather than regulatory or compliance constraints.

The SLPX682M063H3P3 offers extended lifetime rating of 3000 hours at 85°C compared to 2000 hours for the primary part, providing enhanced reliability margin in thermally demanding environments. The B41231C8688M000 provides the highest ripple current capability at 120 Hz (5.04 A), suitable for applications with elevated AC current stress. The 861010786021 and B41231C8688M000 share identical maximum seated height of 1.260" (32.00 mm), while the SLPX682M063H3P3 is 0.079" (2.00 mm) shorter at 1.181" (30.00 mm), which may provide board layout advantages in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can SLPX682M063H3P3 be used as a direct replacement for 861010786021?

A: Yes. Both parts maintain identical capacitance (6800 µF), voltage rating (63 V), tolerance (±20%), lead spacing (10.00 mm), case diameter (35.00 mm), package configuration (Radial, Can - Snap-In), and operating temperature range (-40°C to 85°C). The SLPX682M063H3P3 has a lower maximum seated height (1.181" vs 1.260"), which is compatible with board layouts designed for the taller component.

Q: What is the difference between B41231C8688M000 and 861010786021?

A: Both parts are electrically and mechanically equivalent with identical capacitance, voltage, tolerance, lead spacing, case diameter, and maximum seated height. The primary difference is manufacturer (EPCOS - TDK Electronics vs Würth Elektronik) and ripple current capability at 120 Hz (5.04 A vs 4.32 A). Both maintain 2000 hour lifetime at 85°C.

Q: Are there height restrictions when substituting SLPX682M063H3P3?

A: The SLPX682M063H3P3 has a maximum seated height of 1.181" (30.00 mm), which is 0.079" (2.00 mm) shorter than the 861010786021 and B41231C8688M000 at 1.260" (32.00 mm). This shorter height is compatible with designs accommodating the taller components, but verify clearance if the original design has height constraints.

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

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry Active product status. No compliance or regulatory differences exist among these alternatives.

Q: Which substitute part offers the best thermal performance?

A: The SLPX682M063H3P3 provides 3000 hour lifetime at 85°C, compared to 2000 hours for both the 861010786021 and B41231C8688M000. This extended lifetime indicates superior thermal performance in sustained high-temperature operation.
