Panasonic 6TPU22MSI Equivalent & Substitute Parts

Part Overview

The Panasonic 6TPU22MSI is a 22 µF molded tantalum polymer capacitor rated at 6.3 V in 0805 (2012 Metric) surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The POSCAP™ TPU series represents a mature technology platform, and suitable substitutes exist within the tantalum polymer capacitor category that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Panasonic 6TPU22MSI is determined by the following critical parameters:

• Capacitance Value: Must be 22 µF (±20% tolerance acceptable)
• Voltage Rating: Must be 6.3 V or higher
• Package / Case: Must be 0805 (2012 Metric) for PCB footprint compatibility
• Type: Molded tantalum polymer construction
• Mounting Type: Surface mount configuration

The Nichicon F380J226MSA meets all substitution criteria. While it exhibits a higher ESR specification (200 mOhm @ 100kHz versus 150 mOhm @ 100kHz) and an extended operating temperature range (-55°C ~ 105°C), these parameters remain within acceptable tolerance for general-purpose applications and do not preclude functional equivalence in the specified package and electrical rating.

Parameter Comparison

Engineering Selection Recommendations

Both the Panasonic 6TPU22MSI and Nichicon F380J226MSA are classified as obsolete products. Selection between these components should be based on:

• Compliance Requirements: The Panasonic part is ROHS3 compliant with MSL 3 (168 Hours). The Nichicon part is REACH unaffected with MSL 1 (Unlimited), offering superior moisture handling characteristics.
• Thermal Performance: The Nichicon F380J226MSA supports an extended operating temperature range to 105°C, providing additional thermal margin compared to the 85°C maximum of the Panasonic part.
• ESR Specification: The Panasonic part specifies 150 mOhm ESR, while the Nichicon part specifies 200 mOhm ESR. Applications sensitive to ESR performance should account for this 50 mOhm differential.
• Physical Clearance: The Nichicon part has a maximum seated height of 0.035" (0.90mm) versus 0.039" (1.00mm) for the Panasonic part, providing additional PCB clearance margin.

Frequently Asked Questions (FAQ)

Q: Can the Nichicon F380J226MSA directly replace the Panasonic 6TPU22MSI?

A: Yes, for applications where the 0805 (2012 Metric) package footprint is used and the 22 µF capacitance at 6.3 V rating is required. Both components are molded tantalum polymer capacitors with identical electrical ratings and package dimensions. Verify that the higher ESR specification (200 mOhm versus 150 mOhm) is acceptable for your circuit design.

Q: What is the significance of the ESR difference between these parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and voltage drop characteristics. The Nichicon part's 200 mOhm ESR is 50 mOhm higher than the Panasonic part's 150 mOhm specification. For general-purpose applications, this difference is typically not critical. High-frequency or high-ripple-current applications should evaluate circuit performance with the higher ESR value.

Q: Are there physical compatibility concerns?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The Nichicon part has a lower maximum seated height (0.035" versus 0.039"), which provides additional clearance and does not create compatibility issues.

Q: What is the difference in moisture sensitivity levels?

A: The Panasonic part specifies MSL 3 (168 Hours), while the Nichicon part specifies MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and allows unlimited shelf life without baking requirements, whereas MSL 3 requires baking after 168 hours of exposure to ambient humidity.

Q: Are both parts still available for procurement?

A: Both components are classified as obsolete. Inventory availability should be confirmed with authorized distributors. The Panasonic part shows 8077 pieces in stock, while the Nichicon part shows 1067 pieces in stock at the time of this reference.
