T520V227M2R5ASE009 Equivalent & Substitute Parts

Part Overview

The T520V227M2R5ASE009 is a 220 µF molded tantalum polymer capacitor rated at 2.5 V, manufactured by KEMET in the KO-CAP® T520 series. This component features a 2917 (7343 Metric) package with 9 mOhm equivalent series resistance at 100 kHz and operates across a temperature range of -55°C to 105°C with a 2000-hour lifetime rating at 105°C.

The T520V227M2R5ASE009 is classified as obsolete. Direct substitution requires identifying active production alternatives that maintain electrical and mechanical compatibility while meeting current design requirements. Substitute parts are available in both direct equivalents and upgraded voltage ratings within the same physical package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520V227M2R5ASE009 is determined by the following criteria:

Primary Compatibility Parameters:

• Capacitance: 220 µF (fixed)
• Package / Case: 2917 (7343 Metric) (fixed)
• Mounting Type: Surface Mount (fixed)
• Tolerance: ±20% (fixed)
• Operating Temperature Range: -55°C to 105°C (fixed)
• Type: Molded Tantalum Polymer (fixed)

Variable Parameters Affecting Substitution:

• Voltage Rating: 2.5 V (main part) to 4 V or 6.3 V (upgrades)
• ESR @ 100 kHz: 7 mOhm to 25 mOhm
• Packaging Format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®
• Product Status: Obsolete (main part) to Active (substitutes)
• Series: KO-CAP® T520 or KO-CAP® T528
• Height - Seated (Max): 0.075" (1.90 mm) for T520 series; 0.067" (1.70 mm) for T528 series

Substitute parts are grouped into three categories:

1. Direct Equivalent (Same Voltage, Active Status): T520V227M2R5ATE009 maintains identical electrical specifications with active product status and Tape & Reel packaging.

2. Voltage Upgrade (Higher Rated Voltage, Same Capacitance): T520V227M004ATE009, T520V227M006ATE009, T528Z227M004ATE009, and T528Z227M006ATE009 provide higher voltage ratings (4 V or 6.3 V) within the same physical footprint, suitable for applications requiring increased voltage margin.

3. ESR Variants (Same Voltage, Different ESR): T520V227M2R5ATE007, T520V227M2R5ATE012, T520V227M2R5ATE015, and T520V227M2R5ATE025 offer alternative ESR values at the original 2.5 V rating, accommodating different ripple current and thermal performance requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Recommended for Obsolete Part Phaseout):

T520V227M2R5ATE009 is the primary substitute for T520V227M2R5ASE009. Both components share identical electrical specifications (220 µF, 2.5 V, 9 mOhm ESR) and mechanical dimensions. The substitute is in active production status with ROHS3 compliance and REACH unaffected certification. The transition from unspecified packaging (ASE009) to Tape & Reel format (ATE009) aligns with standard manufacturing practices for active components.

Voltage Upgrade Path (For Enhanced Design Margin):

T520V227M004ATE009 and T520V227M006ATE009 provide 4 V and 6.3 V ratings respectively while maintaining the same 220 µF capacitance and 9 mOhm ESR. These upgrades are suitable when circuit design permits higher voltage ratings and require active production status. Both are ROHS3 compliant and REACH unaffected.

T528Z227M004ATE009 and T528Z227M006ATE009 offer the same voltage upgrades with reduced seated height (1.70 mm versus 1.90 mm), enabling space-constrained applications. These components are from the KO-CAP® T528 series and maintain all compliance certifications.

ESR Variant Selection (For Specific Ripple Current Requirements):

T520V227M2R5ATE007 provides reduced ESR (7 mOhm) at the original 2.5 V rating, suitable for applications requiring lower impedance. T520V227M2R5ATE012, T520V227M2R5ATE015, and T520V227M2R5ATE025 offer progressively higher ESR values for applications with different thermal or ripple current constraints. All ESR variants maintain the same 2.5 V rating and 220 µF capacitance.

All substitute parts are ROHS3 compliant, REACH unaffected, and rated for -55°C to 105°C operation with MSL 3 (168 Hours) moisture sensitivity.

Frequently Asked Questions (FAQ)

Q: Can T520V227M2R5ATE009 directly replace T520V227M2R5ASE009 in existing designs?

A: Yes. T520V227M2R5ATE009 is electrically and mechanically identical to the obsolete T520V227M2R5ASE009. Both feature 220 µF capacitance, 2.5 V rating, 9 mOhm ESR at 100 kHz, and 2917 (7343 Metric) package dimensions. The primary difference is product status (active versus obsolete) and packaging format (Tape & Reel versus unspecified). No circuit modifications are required.

Q: What is the difference between T520 and T528 series substitutes?

A: Both T520 and T528 series are molded tantalum polymer capacitors with identical electrical specifications (220 µF, voltage ratings, ESR). The primary difference is seated height: T520 series measures 1.90 mm maximum, while T528 series measures 1.70 mm maximum. T528 variants are suitable for space-constrained PCB layouts. All other parameters, including capacitance, voltage, and ESR, remain equivalent.

Q: Can I use T520V227M004ATE009 (4 V) instead of T520V227M2R5ATE009 (2.5 V)?

A: Yes, with circuit design verification. T520V227M004ATE009 provides higher voltage rating (4 V versus 2.5 V) while maintaining identical capacitance (220 µF) and ESR (9 mOhm). Higher voltage rating components are suitable for applications where circuit voltage does not exceed the component rating. This substitution increases voltage margin and is mechanically compatible. Verify that the 4 V rating aligns with circuit requirements.

Q: What does ESR variation mean for component selection?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values (7 mOhm in T520V227M2R5ATE007) reduce impedance and heat generation under AC ripple conditions. Higher ESR values (25 mOhm in T520V227M2R5ATE025) are suitable for lower ripple current applications. Select ESR based on circuit ripple current specifications and thermal constraints. All ESR variants maintain the same 220 µF capacitance and 2.5 V rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (T520V227M2R5ATE009, T520V227M004ATE009, T520V227M006ATE009, T528Z227M004ATE009, T528Z227M006ATE009, and all ESR variants) are ROHS3 compliant and REACH unaffected. These certifications apply to both direct equivalents and voltage/ESR variants.

Q: What packaging formats are available for these substitutes?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, and unspecified formats. T520V227M2R5ATE009 (direct equivalent) is supplied in Tape & Reel format. T520V227M006ATE009 and T520V227M2R5ATE012 are available in Cut Tape & Digi-Reel® format. Most voltage upgrade and ESR variants are supplied in Tape & Reel format. Verify packaging format compatibility with assembly equipment before procurement.

Q: Is the MSL (Moisture Sensitivity Level) rating the same across all substitutes?

A: Yes. All substitute parts maintain MSL 3 (168 Hours) rating, identical to the original T520V227M2R5ASE009. This rating applies to storage and handling conditions prior to reflow soldering. Components must be stored in controlled humidity environments and baked according to IPC standards if moisture absorption limits are exceeded.
