Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATB477M010 is based on maintaining the following core electrical and mechanical parameters:

Fixed Parameters (Must Match):

• Capacitance: 470 µF
• Tolerance: ±20%
• Operating Temperature Range: -55°C ~ 105°C
• Lifetime: 5000 Hrs @ 105°C
• Ripple Current @ 120 Hz: 595 mA
• Ripple Current @ 100 kHz: 850 mA
• Package / Case: Radial, Can - SMD
• Physical Dimensions: 0.394" Dia (10.00mm), Height 0.413" (10.50mm)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (May Differ):

• Voltage - Rated: Higher voltage ratings are acceptable substitutes
• ESR @ 120Hz: Lower ESR values indicate improved performance
• Surface Mount Land Size: Minor variations acceptable within manufacturing tolerances

The ATB477M016 qualifies as a substitute because it maintains all fixed parameters while providing an upgraded voltage rating of 16 V and improved ESR performance.

Parameter Comparison

Engineering Selection Recommendations

Both the ATB477M010 and ATB477M016 are Active status components manufactured by Cornell Dubilier / Illinois Capacitor within the ATB series. Both parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

The ATB477M016 provides a higher voltage rating (16 V versus 10 V) while maintaining identical capacitance, tolerance, temperature range, and ripple current specifications. The substitute part also demonstrates improved electrical performance with lower ESR (540 mOhm versus 730 mOhm at 120 Hz).

Component selection between these parts depends on circuit voltage requirements. The ATB477M010 is suitable for applications with maximum operating voltages at or below 10 V. The ATB477M016 is appropriate for circuits requiring operation at voltages up to 16 V or where improved ESR performance is beneficial. Both parts are physically and mechanically interchangeable on the PCB due to identical package dimensions and surface mount land size compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ATB477M016 be used in place of the ATB477M010?

A: Yes. The ATB477M016 is a direct substitute for the ATB477M010 in applications where the circuit voltage does not exceed 16 V. The substitute maintains identical capacitance (470 µF), tolerance (±20%), temperature range (-55°C to 105°C), and ripple current ratings. The higher voltage rating of the substitute provides additional design margin and improved ESR performance.

Q: Are there physical differences between these parts?

A: No. Both parts share identical physical dimensions: 0.394" diameter (10.00mm) and 0.413" maximum seated height (10.50mm). Both are surface mount radial can packages. Minor variations in surface mount land size (ATB477M010: 0.425" L x 0.413" W; ATB477M016: 0.406" L x 0.417" W) fall within standard manufacturing tolerances and do not affect PCB layout compatibility.

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

A: The ATB477M010 has an ESR of 730 mOhm at 120 Hz, while the ATB477M016 has an ESR of 540 mOhm at 120 Hz. Lower ESR in the substitute part results in reduced heat generation and improved high-frequency performance in bypass and decoupling applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the ATB477M010 and ATB477M016 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What applications are these capacitors designed for?

A: Both parts are specified for bypass and decoupling applications. They are suitable for power supply filtering, signal coupling, and noise suppression in electronic circuits operating within the specified voltage and temperature ranges.

Q: Can I use the ATB477M010 in a circuit designed for the ATB477M016?

A: No. The ATB477M010 has a lower voltage rating (10 V) than the ATB477M016 (16 V). Using the lower-rated part in a circuit designed for higher voltage operation may result in capacitor failure or degraded performance.
