Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a direct substitute?

A: Yes. A capacitor with a higher voltage rating (16 V, 25 V, or 35 V) can replace the 10 V original part, provided all other electrical and mechanical parameters remain identical. Higher voltage ratings provide increased safety margin and do not degrade circuit performance in applications designed for 10 V operation.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing determines whether a capacitor can be mounted directly into existing PCB holes without modification. The original part specifies 0.098" (2.50 mm) lead spacing. The Nichicon UHE1E101MED1TA has 0.197" (5.00 mm) spacing and cannot be used as a direct substitute without PCB rework. All other listed substitutes maintain the correct 0.098" (2.50 mm) spacing.

Q: Does physical height affect substitution compatibility?

A: Physical height must be verified against available clearance in the target application. The original part specifies a maximum seated height of 0.492" (12.50 mm). The Panasonic EEU-EB1E101SH has a height of 0.480" (12.20 mm), which is acceptable if clearance permits. All other substitutes match the original 0.492" (12.50 mm) specification.

Q: What is the difference between ripple current ratings?

A: Ripple current capacity indicates the maximum AC current the capacitor can handle without exceeding temperature limits. Higher ripple current ratings provide margin for applications with significant AC ripple. Substitutes with equal or higher ripple current ratings are acceptable.

Q: Why do some parts have "Not For New Designs" status?

A: Parts marked "Not For New Designs" are in declining production or transitional phases. These parts may have limited availability or uncertain long-term supply. For new circuit designs, select parts with Active status.

Q: What does "Last Time Buy" status mean?

A: "Last Time Buy" indicates the manufacturer will cease production after a specified date. Inventory is limited. These parts are not suitable for new designs or applications requiring long-term component availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original part's environmental compliance status.

Q: Can I substitute based on ripple current alone?

A: No. Ripple current is one of several parameters. Substitution requires matching capacitance, tolerance, voltage rating, polarization, package type, mounting type, lead spacing, and physical dimensions. Ripple current is a secondary consideration for applications with specific AC current requirements.
