SR211C472KAATR1 Equivalent & Substitute Parts

Part Overview

The SR211C472KAATR1 is a 4700 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and currently active in production with 1139 units in stock.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for voltage or dimensional variations that enable component standardization across multiple applications.

Substitute Part Grouping Explanation

Substitution of the SR211C472KAATR1 is determined by strict equivalence in the following electrical parameters: capacitance value (4700 pF), tolerance (±10%), voltage rating (100V minimum), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). All substitute parts must maintain through-hole radial mounting configuration and ROHS3 compliance.

Mechanical variations in lead spacing, lead style, and physical dimensions are permissible when the substitute part physically fits the PCB layout and the lead configuration is compatible with the assembly process. Packaging format variations (Tape & Reel, Cut Tape, or Bulk) do not affect electrical equivalence but impact procurement and manufacturing workflows.

The substitute parts are organized into three categories:

Direct Equivalents (Same Voltage Rating): Parts with identical electrical specifications and 100V rating, differing only in packaging format or minor dimensional characteristics.

Direct Equivalents (Different Manufacturers): Parts from alternative manufacturers meeting all electrical and mechanical requirements at 100V rating.

Upgrade Options (Higher Voltage Rating): Parts with 200V or 630V ratings that provide enhanced voltage margin while maintaining all other electrical specifications. These are suitable for applications where the design allows higher voltage components.

Engineering Selection Recommendations

For Direct Replacement (100V Rating):

KEMET C317C472K1R5TA and C322C472K1R5TA are active production parts with identical electrical specifications and 0.200" lead spacing matching the original SR211C472KAATR1. Both are ROHS3 compliant with 28,951 and 1,508 units in stock respectively, providing high availability for immediate procurement.

Murata Electronics RDER72A472K0K1H03B and RDER72A472K0M1H03A maintain electrical equivalence with 0.197" lead spacing and kinked formed leads. Both are ROHS3 compliant and active in production with 1,839 and 4,422 units available.

Vishay Beyschlag K472K15X7RH5UH5 provides electrical equivalence with 0.197" lead spacing and 18,379 units in stock, supporting high-volume applications.

KYOCERA AVX SR151C472KAR and SR151C472KARTR2 are manufacturer-direct alternatives with reduced lead spacing (0.100") and straight leads, suitable for compact PCB layouts. Both maintain full electrical equivalence and ROHS3 compliance.

For Voltage Upgrade Applications:

KEMET C322C472K2R5TA provides 200V rating in the same physical package as the 100V equivalent, enabling single-component standardization across designs with varying voltage requirements. This part is ROHS3 compliant and active with 2,300 units in stock.

Murata Electronics RDER72J472K2K1H03B offers 630V rating for applications requiring maximum voltage margin. This part is ROHS3 compliant and active with 1,542 units in stock.

TDK Corporation FK26X7R2J472KN000 provides 630V rating but carries "Not For New Designs" status, limiting its use to legacy system support or existing inventory management.

Frequently Asked Questions (FAQ)

Q: Can SR151C472KAR substitute for SR211C472KAATR1 in my design?

A: Electrical substitution is valid. Both parts share identical capacitance (4700 pF), voltage rating (100V), tolerance (±10%), and temperature coefficient (X7R). The primary difference is lead spacing: SR151C472KAR uses 0.100" spacing versus 0.200" on the original part. PCB layout compatibility must be verified before implementation.

Q: What is the difference between the KYOCERA AVX SR151C472KAR and SR151C472KARTR2?

A: Both parts are electrically identical with the same lead spacing (0.100") and straight lead style. The difference is packaging format: SR151C472KAR is supplied in Bulk, while SR151C472KARTR2 is supplied in Cut Tape. Selection depends on manufacturing process requirements and procurement workflow.

Q: Are KEMET C317C472K1R5TA and C322C472K1R5TA interchangeable?

A: Both parts are electrically identical with 100V rating and 0.200" lead spacing. The difference is physical size: C317C uses 0.150" length while C322C uses 0.200" length. Verify PCB footprint compatibility before substitution.

Q: Can I use a 200V or 630V rated part instead of the 100V SR211C472KAATR1?

A: Yes, higher voltage-rated parts with identical capacitance, tolerance, and temperature coefficient are electrically compatible. KEMET C322C472K2R5TA (200V) and Murata RDER72J472K2K1H03B (630V) are suitable upgrades. Physical dimensions must be verified for PCB fit.

Q: Why is TDK FK26X7R2J472KN000 marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. While electrically functional, it should not be selected for new product development. Use active production alternatives such as Murata RDER72J472K2K1H03B for 630V applications.

Q: What does lead spacing mean and why does it matter?

A: Lead spacing is the distance between the two leads of the radial capacitor. The original part uses 0.200" spacing, while some substitutes use 0.100" or 0.197" spacing. The PCB must have holes drilled at the correct spacing to accommodate the component. Verify your PCB layout before selecting a substitute with different lead spacing.

Q: Are all listed parts ROHS3 compliant?

A: All parts except TDK FK26X7R2J472KN000 are explicitly ROHS3 compliant. Compliance status for FK26X7R2J472KN000 is also ROHS3 compliant, but the part carries "Not For New Designs" status for other reasons.
