Equivalent & Substitute Parts for 2R5TPU47MSI

Part Overview

The 2R5TPU47MSI is a 47 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, rated for 2.5 V operation in a 0805 (2012 Metric) surface mount package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. The POSCAP™ TPU series design provides low ESR characteristics suitable for general-purpose filtering and energy storage in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2R5TPU47MSI is determined by the following critical parameters:

• Capacitance Value: Must be 47 µF (±20% tolerance acceptable)
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Type: Molded Tantalum Polymer construction
• Voltage Rating: Must equal or exceed 2.5 V rated voltage
• Operating Temperature Range: Must support -55°C to 85°C minimum
• Tolerance: ±20% acceptable

The substitute part F380J476MSA meets all mechanical compatibility requirements and electrical parameter criteria, with the exception of an elevated voltage rating (6.3 V) and slightly higher ESR (200 mOhm @ 100kHz). These differences represent acceptable trade-offs for component availability.

Parameter Comparison

Engineering Selection Recommendations

The F380J476MSA from KYOCERA AVX serves as a direct mechanical and electrical substitute for the obsolete 2R5TPU47MSI. Both components are ROHS3 compliant and share identical package dimensions, mounting characteristics, and moisture sensitivity ratings. The substitute part maintains the same capacitance value and tolerance specification.

The elevated voltage rating of the F380J476MSA (6.3 V versus 2.5 V) provides additional design margin in applications where the original 2.5 V rating was adequate. The increased ESR (200 mOhm versus 150 mOhm) represents a minor performance trade-off acceptable in general-purpose filtering applications. The extended operating temperature range (-55°C to 105°C) of the substitute part offers improved thermal performance compared to the original specification.

Both components are classified as not suitable for new designs, indicating industry-wide transition away from this capacitor technology. For new product development, evaluation of alternative capacitor technologies and form factors is recommended based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the F380J476MSA directly replace the 2R5TPU47MSI in existing designs?

A: Yes. Both components share identical package dimensions (0805 / 2012 Metric), mounting type (Surface Mount), capacitance value (47 µF), and tolerance (±20%). Mechanical and electrical compatibility is confirmed for PCB assembly and circuit operation.

Q: What is the significance of the voltage rating difference?

A: The F380J476MSA is rated for 6.3 V, exceeding the original 2.5 V specification. This higher rating does not create compatibility issues in circuits designed for 2.5 V operation. The substitute part operates safely at lower voltages with increased design margin.

Q: How does the ESR difference affect circuit performance?

A: The F380J476MSA exhibits 200 mOhm ESR compared to 150 mOhm for the original part. This 50 mOhm increase is negligible in general-purpose filtering applications. For noise-sensitive or high-frequency applications, ESR performance should be verified against specific circuit requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the 2R5TPU47MSI and F380J476MSA are ROHS3 compliant and share identical Moisture Sensitivity Level 3 (168 Hours) ratings, ensuring equivalent handling and storage requirements.

Q: Why is the substitute part classified as "Not For New Designs"?

A: Both the original and substitute components represent mature tantalum polymer capacitor technology. Industry transition toward alternative capacitor chemistries and form factors is ongoing. New product designs should evaluate current-generation alternatives based on application-specific performance and reliability requirements.
