• Tolerance: ±20% (no variation)
• ESR: 320 mOhm @ 100 kHz (no variation)
• Lifetime: 5000 Hrs @ 105°C (no variation)
• Operating Temperature Range: -55°C ~ 105°C (no variation)
• Ripple Current @ Low Frequency: 375 mA @ 120 Hz (no variation)
• Package Type: Radial, Can - SMD (no variation)
• PCB Land Size: 0.531" L x 0.590" W (13.50 mm x 15.00 mm) (no variation)
• Mounting Type: Surface Mount (no variation)
• Automotive Rating: AEC-Q200 (no variation)
• Compliance: ROHS3, RoHS Unaffected, EAR99 classification (no variation)

The substitute part AFK686M2AH32T-F differs only in physical height and ripple current specifications at high frequency, with all critical electrical parameters and qualification standards remaining identical.

Parameter Comparison

Engineering Selection Recommendations

Both AFK686M2AH32VT-F and AFK686M2AH32T-F are Active products from Cornell Dubilier Electronics with identical electrical specifications and AEC-Q200 automotive qualification. The primary selection difference is physical height, where the AFK686M2AH32T-F offers a 0.3 mm reduction (14.00 mm versus 14.30 mm maximum seated height). Both parts are ROHS3 compliant, carry unlimited moisture sensitivity level (MSL 1), and maintain identical PCB land requirements. Selection between these parts depends on available inventory and PCB clearance constraints.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Yes. Both parts are surface mount radial can packages with identical PCB land size specifications of 0.531" L × 0.590" W (13.50 mm × 15.00 mm).

Q: Can I substitute AFK686M2AH32T-F for AFK686M2AH32VT-F without design changes? A: Direct substitution is supported for applications where the 0.3 mm height difference (14.00 mm maximum versus 14.30 mm maximum) does not impact PCB clearance. Both parts carry identical electrical parameters, capacitance, voltage rating, ESR, operating temperature range, and lifetime specifications.

Q: Are there any compliance differences between these parts? A: No. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and are REACH Unaffected. Both meet AEC-Q200 automotive qualification standards.

Q: What is the difference in ripple current handling? A: Both parts support 375 mA ripple current at 120 Hz. The AFK686M2AH32T-F additionally specifies 500 mA at 100 kHz; this specification is not provided for the AFK686M2AH32VT-F.

Q: Do these parts differ in temperature performance? A: No. Both parts operate across the same temperature range (-55°C ~ 105°C) and share identical lifetime specifications of 5000 hours at 105°C.
