AFK107M06C12B-F Equivalent & Substitute Parts

Part Overview

The AFK107M06C12B-F is a 100 µF, 6.3 V aluminum electrolytic capacitor in a radial, can-style surface mount package manufactured by Cornell Dubilier Electronics (CDE). This component is rated for automotive applications with AEC-Q200 compliance and a 2000-hour lifetime at 105°C. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain resilience.

Substitute Part Grouping Explanation

Electrical substitution is determined by matching the core parameters: capacitance (100 µF), tolerance (±20%), rated voltage (6.3 V), lifetime rating (2000 hours @ 105°C), operating temperature range (-55°C to 105°C), and AEC-Q200 automotive qualification. Mechanical substitution requires identical case diameter (5.00 mm), height (6.10 mm maximum seated), polarization (polar), mounting type (surface mount), and package configuration (radial, can - SMD). All identified substitute parts satisfy these electrical and mechanical criteria and are supplied from active manufacturers with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can I use the Panasonic EEE-FKJ101UAR as a substitute for the AFK107M06C12B-F? A: The EEE-FKJ101UAR is electrically and mechanically compatible with identical capacitance, voltage, tolerance, and lifetime ratings. Low-frequency ripple current is 104 mA compared to the original 120 mA specification. Confirm circuit design margins accommodate this variation before implementation.

Q: What is the primary difference between the Chemi-Con EMZA6R3ARA101ME61G and the original part? A: The EMZA6R3ARA101ME61G provides higher ripple current capacity at 100 kHz (240 mA versus 160 mA) but lower ripple current at 120 Hz (96 mA versus 120 mA). Low-frequency circuit design should be evaluated to ensure compatibility.

Q: Is the Nichicon UCL0J101MCL6GS a direct substitute? A: Electrical parameters are compatible (capacitance, voltage, tolerance, lifetime). ESR is lower at 360 mOhm. The part height is 5.80 mm instead of 6.10 mm, reducing clearance margins. AEC-Q200 automotive qualification is not specified for this part; applications requiring automotive compliance should select Panasonic or Chemi-Con alternatives.

Q: Do all substitute parts have the same surface mount land size? A: The original AFK107M06C12B-F specifies 5.30 mm x 6.50 mm land size. All substitute parts use standard 5.30 mm x 5.30 mm footprint. PCB land pattern modification is required for mechanical fit compatibility.

Q: Are moisture sensitivity levels identical across all parts? A: All parts, including the original and substitutes, are rated MSL 1 (Unlimited). No moisture bake requirements apply prior to assembly.
