Key Parameters

Substitute Part Grouping Explanation

Substitution of the SR211C472KAATR2 is determined by alignment of the following critical parameters:

• Capacitance Value: 4700 pF (472 in part number designation)
• Voltage Rating: 100V (minimum requirement)
• Temperature Coefficient: X7R (standard ceramic dielectric)
• Tolerance: ±10%
• Mounting Configuration: Radial through-hole leads
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Operating Temperature Range: -55°C to 125°C

The substitute part C322C472K1R5TA from KEMET meets all these parameters and is classified as an equivalent component for this application.

Frequently Asked Questions (FAQ)

Q: Can C322C472K1R5TA be used as a direct replacement for SR211C472KAATR2 in PCB assembly?

A: Yes. Both parts have identical capacitance (4700 pF), voltage rating (100V), temperature coefficient (X7R), tolerance (±10%), and radial through-hole lead configuration. They are electrically and mechanically interchangeable.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is used for automated pick-and-place assembly equipment. Bulk packaging is used for manual assembly or alternative handling methods. The electrical component itself is identical; only the delivery format differs.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both SR211C472KAATR2 and C322C472K1R5TA are ROHS3 Compliant and REACH Unaffected, meeting current environmental standards for electronic components.

Q: What does the X7R temperature coefficient indicate?

A: X7R indicates a ceramic dielectric material with a temperature coefficient of ±15% over the operating range of -55°C to 125°C. This is a standard specification for general-purpose ceramic capacitors.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB layout accommodates the radial lead spacing of 0.200" (5.08mm) and the physical dimensions are compatible with the available board space. Both parts meet this specification.
