KEMET T520D227M010ASE018 Equivalent & Substitute Parts

Part Overview

The KEMET T520D227M010ASE018 is a 220 µF molded tantalum polymer capacitor rated at 10 V with an ESR of 18 mOhm @ 100 kHz, housed in a 2917 (7343 Metric) surface mount package. This component is classified as obsolete and has been superseded by active production alternatives within the KO-CAP® T520 series and cross-manufacturer equivalents.

Substitution Categories:

Category 1: Direct KEMET KO-CAP® T520 Series Substitutes (Active Status) These parts share identical electrical specifications and differ only in packaging format or manufacturing lot codes. All are manufactured by KEMET and maintain full parametric equivalence.

Category 2: Parametric KEMET KO-CAP® T520 Series Equivalents (Active Status) These parts maintain identical electrical and mechanical specifications but are distributed under different packaging configurations or lot designations.

Category 3: Cross-Manufacturer Equivalent (Panasonic POSCAP™ TPE Series) The Panasonic 10TPE220MIL provides parametric equivalence across all critical specifications. Physical dimensions vary slightly (height seated maximum: 3.00 mm vs. 3.10 mm), remaining within acceptable PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can T520D227M010ATE018 directly replace the obsolete T520D227M010ASE018?

A: Yes. Both parts share identical electrical specifications (220 µF, 10 V, 18 mOhm ESR @ 100 kHz), mechanical dimensions (2917 package, 3.10 mm height), and operating parameters (-55°C ~ 105°C, 2000 Hrs @ 105°C). The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. Non-compliant). Electrical and mechanical compatibility is complete.

Q: What is the difference between the various KEMET T520D227M010A part numbers?

A: The suffix codes indicate packaging format and manufacturing lot designation. The base specification T520D227M010A remains constant across all variants. Suffix variations include:

TE018: Cut Tape & Digi-Reel® packaging
AHE018: Tape & Reel packaging
ATE018: Tape & Reel packaging
Numeric suffixes (2478, 7622, 8000, 7824): Manufacturing lot or reel codes

All maintain identical electrical and mechanical parameters.

Q: Is the Panasonic 10TPE220MIL a suitable substitute?

A: Yes. The 10TPE220MIL provides parametric equivalence across all critical specifications: 220 µF capacitance, 10 V rating, 18 mOhm ESR @ 100 kHz, 2917 package, -55°C ~ 105°C operating range, and 2000 Hrs @ 105°C lifetime. The seated height maximum is 3.00 mm versus 3.10 mm for KEMET parts—a 0.10 mm difference within standard PCB assembly tolerances. ROHS3 compliance is confirmed.

Q: Which substitute offers the best availability?

A: The Panasonic 10TPE220MIL provides the highest inventory level at 22,549 Pcs. Among KEMET alternatives, T520D227M010ATE0187622 and T520D227M010ATE0188000 each offer over 1,100 Pcs in stock.

Q: Are there any compliance differences between substitutes?

A: Yes. ROHS3 Compliant options include T520D227M010ATE018, T520D227M010ATE0182478, T520D227M010ATE0187622, T520D227M010ATE0188000, and 10TPE220MIL. Non-compliant alternatives include T520D227M010AHE018, T520D227M010AHE0182478, and T520D227M010AHE0187824. Select based on end-product regulatory requirements.

Q: Can substitutes be mixed in the same assembly?

A: Yes. All listed substitutes maintain identical electrical performance and mechanical fit. Mixed sourcing from KEMET KO-CAP® T520 series or Panasonic POSCAP™ TPE series does not affect circuit functionality or reliability. Verify compliance certifications align with product requirements.

Q: What is the significance of the ESR specification?

A: ESR (Equivalent Series Resistance) of 18 mOhm @ 100 kHz is a critical performance parameter for tantalum polymer capacitors. All substitutes maintain this exact specification, ensuring equivalent ripple current handling, thermal performance, and frequency response characteristics. This parameter must not vary.

Q: Are physical dimensions identical across all substitutes?

A: Dimensions are nearly identical. All parts use the 2917 (7343 Metric) package with length 7.30 mm and width 4.30 mm. Seated height maximum varies slightly: KEMET parts are 3.10 mm; Panasonic 10TPE220MIL is 3.00 mm. This 0.10 mm difference is within standard PCB assembly clearance specifications and does not affect compatibility.
