T520V477M2R5ATE006 Equivalent & Substitute Parts

Part Overview

The T520V477M2R5ATE006 is a 470 µF molded tantalum polymer capacitor rated at 2.5 V, manufactured by KEMET in the KO-CAP® T520 series. This surface mount component features a 2917 (7343 Metric) package with 6 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 part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same capacitance, voltage rating, package dimensions, and performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the T520V477M2R5ATE006 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 470 µF (exact match)
• Voltage rating: 2.5 V (exact match)
• ESR specification: 6 mOhm @ 100 kHz (exact match)
• Tolerance: ±20% (exact match)
• Operating temperature range: -55°C to 105°C (exact match)
• Lifetime rating: 2000 Hrs @ 105°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 2917 (7343 Metric) (exact match)
• Mounting type: Surface Mount (exact match)
• Moisture sensitivity level: 3 (168 Hours) (exact match)

Compliance Requirements:

• RoHS3 Compliant status (exact match)
• REACH Unaffected status (exact match)

The T528Z477M2R5ATE006 qualifies as a direct substitute because it maintains identical electrical performance specifications and package dimensions while differing only in packaging format (Tape & Reel versus Cut Tape) and manufacturer size code designation (Z versus V). These differences do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The T528Z477M2R5ATE006 is a direct functional equivalent to the T520V477M2R5ATE006 for circuit applications requiring 470 µF at 2.5 V with 6 mOhm ESR performance. Both parts maintain identical electrical specifications, thermal ratings, and compliance certifications (ROHS3 Compliant, REACH Unaffected).

The primary distinction between these parts is packaging format and seated height. The T520V477M2R5ATE006 is supplied in Cut Tape (CT) & Digi-Reel® format with a maximum seated height of 0.075" (1.90mm), while the T528Z477M2R5ATE006 is supplied in Tape & Reel (TR) format with a maximum seated height of 0.067" (1.70mm). The T528Z variant offers a lower profile, which may provide advantages in space-constrained applications.

Selection between these parts should be based on:

1. Packaging requirements: Choose Cut Tape format for lower-volume applications or Tape & Reel format for high-volume automated assembly
2. PCB clearance constraints: The T528Z lower seated height (1.70mm) accommodates tighter vertical spacing compared to the T520V (1.90mm)
3. Supply chain availability: Both parts are in active production with current inventory

Both parts are suitable for direct substitution in applications where the original design specification calls for the T520V477M2R5ATE006.

Frequently Asked Questions (FAQ)

Q: Can the T528Z477M2R5ATE006 be used as a direct replacement for the T520V477M2R5ATE006 in existing designs?

A: Yes. The T528Z477M2R5ATE006 maintains identical electrical performance (470 µF, 2.5 V, 6 mOhm ESR) and package dimensions (2917 / 7343 Metric). The primary difference is packaging format (Tape & Reel versus Cut Tape) and a 0.008" (0.20mm) reduction in maximum seated height. This height difference is negligible for most PCB layouts and does not affect functional compatibility.

Q: What is the significance of the different manufacturer size codes (V versus Z)?

A: The manufacturer size codes (V and Z) designate internal KEMET classification within the KO-CAP® product line. These codes do not affect electrical performance or mechanical compatibility. Both codes represent the same 2917 (7343 Metric) package with identical lead spacing and mounting characteristics.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the T520V477M2R5ATE006 and T528Z477M2R5ATE006 carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 3 (168 Hours). Both parts are suitable for applications requiring these regulatory standards.

Q: What is the impact of the 0.008" seated height difference on PCB design?

A: The T528Z477M2R5ATE006 has a maximum seated height of 0.067" (1.70mm) compared to the T520V477M2R5ATE006 at 0.075" (1.90mm). This 0.008" (0.20mm) difference is within typical PCB assembly tolerances and does not require design modifications. The lower profile of the T528Z may provide marginal benefits in applications with strict vertical clearance constraints.

Q: Can these parts be mixed in the same production run?

A: Yes, provided the PCB design accommodates the maximum seated height of 0.075" (1.90mm) from the T520V variant. Since the T528Z is lower profile, it will fit within the same clearance envelope. However, packaging format differences (Cut Tape versus Tape & Reel) require separate handling in automated assembly processes.

Q: What factors should determine which part to select for new designs?

A: Selection should be based on: (1) packaging format preference for your assembly process (Cut Tape for lower volumes, Tape & Reel for high-volume automation), (2) PCB vertical clearance requirements (T528Z offers 0.20mm additional clearance), and (3) supply chain and inventory availability from your component distributor.
