Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): No substitute parts maintain the exact 25 V rating. The lowest voltage upgrade available is 860020572002 at 35 V, suitable for applications where the circuit design permits higher voltage tolerance.

For Voltage Margin Enhancement: Parts 860020572002 (35 V), 860020672009 (50 V), 860020772009 (63 V), and UHE2A6R8MDD1TD (100 V) provide progressively higher voltage ratings. Selection depends on circuit voltage requirements and design safety margins.

For Extended Lifetime: 860160672007 (4000 Hrs @ 105°C), 860240672001 (5000 Hrs @ 105°C), and UHE2A6R8MDD1TD (5000 Hrs @ 105°C) offer extended operational life compared to the original 2000-hour rating.

For Improved Ripple Current Handling: 860160672007 provides the highest ripple current capacity at 96 mA @ 100 kHz, followed by 860240672001 at 75 mA @ 100 kHz.

For Active Product Status: All substitute parts except UHE2A6R8MDD1TD maintain Active product status. UHE2A6R8MDD1TD is classified as Obsolete and should be selected only when other options are unsuitable.

For Lead Spacing Compatibility: UHE2A6R8MDD1TD has a lead spacing of 0.098" (2.50 mm), differing from the original 0.079" (2.00 mm). PCB layout verification is required before selection.

UHE2A6R8MDD1TD is a Nichicon product with Obsolete status. Selection between manufacturers depends on supply chain requirements and design specifications.

Q: Does UHE2A6R8MDD1TD require PCB layout changes?

A: UHE2A6R8MDD1TD has a lead spacing of 0.098" (2.50 mm) compared to the original 0.079" (2.00 mm). PCB footprint verification is required. The component may not fit existing through-hole patterns without modification.

Q: Which substitute offers the best ripple current performance?

A: 860160672007 provides the highest ripple current capacity at 96 mA @ 100 kHz, making it suitable for applications requiring superior high-frequency ripple current handling.

Q: Are all substitutes RoHS3 compliant?

A: All substitute parts listed are ROHS3 Compliant, maintaining regulatory compliance with the original component.

Q: What is the minimum voltage rating substitute for a 25 V application?

A: 860020572002 at 35 V is the lowest voltage upgrade available. For applications requiring exact 25 V operation, the original 860020472002 must be used.

Q: Which substitute has the longest operational lifetime?

A: Both 860240672001 and UHE2A6R8MDD1TD offer 5000 Hrs @ 105°C lifetime rating, the highest available among the substitute options.
