6TPU10MSI Equivalent & Substitute Parts

Part Overview

The 6TPU10MSI is a 10 µF molded tantalum polymer capacitor manufactured by Panasonic Electronic Components, rated for 6.3 V operation in a 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 continuity. The part operates across a temperature range of -55°C to 85°C with an ESR of 250 mOhm @ 100 kHz and is RoHS3 compliant with MSL 3 moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6TPU10MSI is determined by strict equivalence across the following critical parameters:

• Capacitance value: 10 µF (exact match required)
• Voltage rating: 6.3 V (minimum acceptable rating)
• Package footprint: 0805 (2012 Metric) surface mount (physical and electrical compatibility)
• Component type: Molded tantalum polymer (functional equivalence)
• Tolerance: ±20% (electrical performance specification)
• RoHS3 compliance and MSL 3 rating (regulatory and manufacturing process compatibility)

The substitute part T55P106M6R3C0500 from Vishay Sprague meets all these criteria. Variations in ESR, operating temperature range, and physical height do not preclude substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The T55P106M6R3C0500 is a direct functional substitute for the 6TPU10MSI. Both components share identical capacitance, voltage rating, tolerance, package footprint, and compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The T55P106M6R3C0500 exhibits a higher ESR value (500 mOhm versus 250 mOhm @ 100 kHz) and an extended operating temperature range (-55°C to 105°C versus -55°C to 85°C). These differences do not compromise substitution validity when the original design specifications do not mandate the lower ESR or narrower temperature range of the obsolete part.

Physical height variation (1.20mm maximum seated height for the substitute versus 1.00mm for the original) must be evaluated within the context of board layout and clearance requirements. The footprint remains identical, and the height difference is within typical PCB assembly tolerances for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can the T55P106M6R3C0500 be used as a direct replacement for the 6TPU10MSI in existing designs?

A: Yes. Both parts share the same capacitance (10 µF), voltage rating (6.3 V), tolerance (±20%), package footprint (0805), and component type (molded tantalum polymer). The substitute part is RoHS3 compliant with MSL 3 rating, matching the original specification.

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

A: The T55P106M6R3C0500 has an ESR of 500 mOhm @ 100 kHz compared to 250 mOhm for the 6TPU10MSI. ESR affects ripple current handling and thermal performance. If the original design does not specify a maximum ESR requirement, the higher value does not preclude substitution. Applications with strict ESR limitations should be evaluated against the substitute part's specification.

Q: Does the height difference affect PCB assembly compatibility?

A: The substitute part has a maximum seated height of 1.20mm compared to 1.00mm for the original. Both maintain the identical 0805 footprint. Height variation must be assessed within the context of board clearance, component stacking, and assembly process requirements. Standard PCB assembly processes accommodate this variation.

Q: Why is the original part obsolete?

A: The 6TPU10MSI is classified as obsolete by Panasonic Electronic Components. The T55P106M6R3C0500 from Vishay Sprague is in active production, providing a viable path for design continuity and procurement support.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS3 compliant and carry MSL 3 (168 Hours) moisture sensitivity ratings. The substitute part includes REACH Unaffected status. No compliance barriers exist for substitution.
