ECS-T1AZ475R Equivalent & Substitute Parts

Part Overview

The ECS-T1AZ475R is a 4.7 µF molded tantalum capacitor rated at 10 V in 0805 (2012 Metric) surface mount package, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-T1AZ475R is determined by strict equivalence across the following parameters:

• Capacitance value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 10 V (exact match required)
• Package type: 0805 (2012 Metric) surface mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Moisture sensitivity level: 1 (exact match required)

The F921A475MPA from KYOCERA AVX meets all substitution criteria. This part maintains identical electrical and mechanical specifications while offering improved product status (Active vs. Obsolete) and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The F921A475MPA is the direct equivalent substitute for the ECS-T1AZ475R. Selection of this alternative is justified by:

• Identical electrical specifications (capacitance, tolerance, voltage rating)
• Identical mechanical compatibility (package, footprint, dimensions)
• Active product status ensuring continued availability and supply chain stability
• ROHS3 compliance, providing regulatory advantage over the non-compliant original part
• Reduced maximum seated height (1.00mm vs. 1.20mm), offering improved PCB layout flexibility

The F921A475MPA is suitable for direct replacement in all applications where the ECS-T1AZ475R was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the F921A475MPA be used as a direct replacement for the ECS-T1AZ475R?

A: Yes. Both parts share identical capacitance (4.7 µF), tolerance (±20%), voltage rating (10 V), package type (0805), and operating temperature range (-55°C ~ 125°C). No circuit modifications are required.

Q: What is the difference in height between these parts?

A: The F921A475MPA has a maximum seated height of 0.039" (1.00mm), compared to 0.047" (1.20mm) for the ECS-T1AZ475R. This 0.20mm difference is within typical PCB design tolerances and does not affect compatibility.

Q: Why is the ECS-T1AZ475R listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Panasonic Electronic Components. The F921A475MPA provides continued access to equivalent functionality from an active product line.

Q: Does the F921A475MPA meet RoHS requirements?

A: Yes. The F921A475MPA is ROHS3 compliant, whereas the ECS-T1AZ475R is RoHS non-compliant. This provides regulatory compliance advantage for new designs and updated production runs.

Q: Are there any ESR (Equivalent Series Resistance) differences?

A: The F921A475MPA specifies 6Ohm ESR. The ECS-T1AZ475R ESR value is not provided in the available data. Both parts are suitable for general purpose applications within their rated specifications.
