4TAE470ML Equivalent & Substitute Parts

Part Overview

The 4TAE470ML is a 470 µF molded tantalum polymer capacitor rated at 4 V, manufactured by Panasonic Electronic Components in the POSCAP™ TA series. This component is designed for surface mount applications in the 2917 (7343 Metric) package with an ESR of 25 mOhm @ 100kHz. The part maintains active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the 4TAE470ML is determined by strict equivalence across the following parameters:

• Capacitance: 470 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• ESR @ 100kHz: 25 mOhm (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Tolerance: ±20% (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

Two substitute parts meet these criteria: the 4TPE470ML (Panasonic Electronic Components, POSCAP™ TPE series) and the T55D477M004C0025 (Vishay Sprague, vPolyTan™ T55 series). Both components are parametrically equivalent across all critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and are suitable for direct substitution based on parametric equivalence. The 4TPE470ML, also from Panasonic Electronic Components, represents an intra-manufacturer alternative within the POSCAP™ polymer capacitor family and carries ROHS3 compliance certification identical to the main part.

The T55D477M004C0025 from Vishay Sprague is a cross-manufacturer equivalent that meets all critical electrical specifications. The seated height of the Vishay part is 0.122" (3.10mm) compared to 0.118" (3.00mm) for the Panasonic parts, a 0.04mm difference that falls within typical PCB assembly tolerances for surface mount components in this package class.

Selection between these substitutes should be based on supply availability, lead time requirements, and procurement preferences. All three parts are electrically and mechanically compatible for applications requiring a 470 µF, 4 V molded tantalum polymer capacitor in the 2917 package.

Frequently Asked Questions (FAQ)

Q: Can the 4TPE470ML be used as a direct replacement for the 4TAE470ML?

A: Yes. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications: 470 µF capacitance, 4 V voltage rating, 25 mOhm ESR @ 100kHz, and 2917 package dimensions. The primary difference is the series designation (TPE versus TA), which reflects internal design evolution within the POSCAP™ polymer capacitor family while maintaining full parametric compatibility.

Q: Is the Vishay T55D477M004C0025 compatible with the 4TAE470ML in existing designs?

A: Yes. The T55D477M004C0025 meets all critical electrical and mechanical parameters. The maximum seated height is 0.122" (3.10mm) compared to 0.118" (3.00mm) for the Panasonic part. This 0.04mm difference is within standard PCB assembly tolerances and does not affect component placement or board-level performance in typical surface mount applications.

Q: What parameters must match exactly for substitution?

A: Capacitance (470 µF), voltage rating (4 V), ESR @ 100kHz (25 mOhm), package type (2917 / 7343 Metric), tolerance (±20%), component type (molded tantalum polymer), operating temperature range (-55°C ~ 105°C), and mounting type (surface mount) must all match exactly. Deviations in any of these parameters disqualify a part from substitution.

Q: Are there packaging differences between these parts?

A: The 4TAE470ML and 4TPE470ML are supplied in Tape & Reel (TR) packaging. The T55D477M004C0025 is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats are standard for surface mount component distribution and do not affect component performance or compatibility.

Q: What is the significance of the different series designations (TA, TPE, T55)?

A: Series designations identify the manufacturer's product line and internal design generation. The 4TAE470ML belongs to Panasonic's POSCAP™ TA series, the 4TPE470ML to the POSCAP™ TPE series, and the T55D477M004C0025 to Vishay's vPolyTan™ T55 series. Despite different series names, all three parts are parametrically equivalent and interchangeable for applications requiring the specified electrical and mechanical characteristics.
