EEE-FT1C101AR Equivalent & Substitute Parts

Part Overview

The EEE-FT1C101AR is a 100 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is classified as Active product status and is designed for automotive applications with AEC-Q200 qualification. Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility is required across multiple qualified suppliers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the EEE-FT1C101AR are qualified based on the following criteria:

Electrical Parameters (Must Match):

Capacitance: 100 µF
Voltage Rating: 16 V
Tolerance: ±20%
Lifetime: 2000 Hrs @ 105°C
Operating Temperature Range: -55°C ~ 105°C
Polarization: Polar

Mechanical Parameters (Must Match):

Package Type: Radial, Can - SMD
Case Diameter: 0.197" (5.00mm)
Case Height: 0.240" (6.10mm)
Land Size: 0.209" L × 0.209" W (5.30mm × 5.30mm)
Mounting Type: Surface Mount

Compliance Parameters (Must Match):

AEC-Q200 Automotive Rating
RoHS3 Compliance
MSL 1 Rating

All substitute parts listed meet these criteria. Variations in ESR (Equivalent Series Resistance) and ripple current ratings are permitted within the same functional category, as these represent performance characteristics rather than compatibility constraints.

Engineering Selection Recommendations

Primary Selection (Active Status, Lowest ESR):

EEE-FT1C101AR (original part) or EMZR160ARA101ME61G or UCM1C101MCL1GS for new designs requiring 360 mOhm ESR performance.

Secondary Selection (Active Status, Higher ESR):

EEE-FN1C101UR for applications where 700 mOhm ESR is acceptable and Panasonic FN series is preferred.

Legacy/Existing Inventory:

EEE-FK1C101SR carries "Not For New Designs" status and should be used only for sustaining production or existing board revisions where design change is not feasible.

All listed parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Selection between parts with identical electrical specifications should prioritize Active product status for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can EEE-FK1C101SR be used in new designs? A: EEE-FK1C101SR carries "Not For New Designs" status. For new designs, select from EEE-FT1C101AR, EEE-FN1C101UR, EMZR160ARA101ME61G, or UCM1C101MCL1GS.

Q: What is the difference between 360 mOhm and 700 mOhm ESR parts? A: ESR affects ripple current handling and heat dissipation. Parts with 360 mOhm ESR (EEE-FT1C101AR, EMZR160ARA101ME61G, UCM1C101MCL1GS) support 240 mA ripple current at 100 kHz. Parts with 700 mOhm ESR (EEE-FK1C101SR, EEE-FN1C101UR) support 160 mA ripple current at 100 kHz. Select based on circuit ripple current requirements.

Q: Are all substitute parts mechanically interchangeable? A: Yes. All listed parts share identical case dimensions (0.197" diameter, 0.240" height), land sizes (0.209" × 0.209"), and surface mount mounting type. PCB layout and footprints are directly compatible.

Q: Which substitute offers the best long-term availability? A: EEE-FN1C101UR (Panasonic, Active status, 5111 pcs in stock) and UCM1C101MCL1GS (Nichicon, Active status, 6907 pcs in stock) both carry Active product status with substantial inventory levels.

Q: Do all parts meet automotive qualification requirements? A: Yes. All listed parts carry AEC-Q200 rating, ROHS3 compliance, and MSL 1 classification, meeting automotive application standards.
