SR201C472KAATR2 Equivalent & Substitute Parts

Part Overview

The SR201C472KAATR2 is a 4700 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX under 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 in active production status with 712 units in stock.

Equivalent and substitute parts are identified when manufacturers discontinue production lines, when alternative packaging formats are required for assembly processes, or when design revisions necessitate component sourcing from multiple suppliers to ensure supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C472KAATR2 is determined by strict equivalence in the following electrical parameters: capacitance value (4700 pF), tolerance (±10%), voltage rating (100V), and temperature coefficient (X7R). All substitute parts must maintain the same operating temperature range (-55°C to 125°C) and mounting configuration (through-hole radial).

Mechanical variations in physical dimensions, lead spacing, and lead style (straight versus formed) are permitted substitutions provided the component fits within the PCB layout constraints of the original design. Packaging format differences (bulk, cut tape, tape and reel) represent logistical variations that do not affect electrical performance.

All identified substitutes are manufactured by established suppliers (KYOCERA AVX, KEMET, Vishay Beyschlag/Draloric/BC Components, and Murata Electronics) and maintain ROHS3 compliance and REACH unaffected status consistent with the primary part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance. Selection between equivalent parts depends on PCB layout constraints and assembly process requirements.

For designs with standard 2.54mm lead spacing and straight lead configuration, SR151C472KAR, SR151C472KARTR2, C315C472K1R5TA, and K472K15X7RH5TL2 provide direct electrical equivalence with compact physical footprints.

For designs requiring larger lead spacing (5.08mm), C317C472K1R5TA and K472K15X7RH5UH5 offer formed lead configurations. RDER72A472K0K1H03B and RDER72A472K0M1H03A provide kinked formed leads suitable for specific PCB hole patterns.

For applications where physical dimensions match the original SR201C472KAATR2 (5.08mm x 3.18mm), C320C472K1R5TA and C322C472K1R5TA maintain identical body dimensions with variations in lead spacing and lead style.

Frequently Asked Questions (FAQ)

Q: Can SR151C472KAR be used as a direct replacement for SR201C472KAATR2?

A: Yes, electrically. Both parts share identical capacitance (4700 pF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The SR151C472KAR has a smaller physical footprint (3.81mm x 2.54mm versus 5.08mm x 3.18mm). Verify PCB layout compatibility before substitution.

Q: What is the difference between straight and formed lead styles?

A: Straight leads are perpendicular to the component body and require standard through-hole PCB patterns. Formed leads are pre-bent at specific angles and spacing to match alternative PCB hole patterns. Formed leads accommodate different lead spacing requirements (5.08mm or 5.00mm versus 2.54mm).

Q: Are KEMET C315C472K1R5TA and KYOCERA AVX SR151C472KAR electrically identical?

A: Yes. Both parts meet the same electrical specifications: 4700 pF capacitance, ±10% tolerance, 100V rating, X7R temperature coefficient, and -55°C to 125°C operating range. Physical dimensions are identical (3.81mm x 2.54mm). Packaging format differs (bulk versus cut tape).

Q: What does "formed leads - kinked" mean in the Murata RDER72A series?

A: Kinked formed leads feature a bend or kink in the lead structure, typically used for specific PCB hole patterns or to accommodate component placement in constrained layouts. The RDER72A472K0K1H03B and RDER72A472K0M1H03A both use this lead style with 5.00mm lead spacing.

Q: Can I substitute a part with different lead spacing?

A: Lead spacing substitution requires PCB redesign or manual lead bending. Standard 2.54mm spacing parts (SR151C472KAR, C315C472K1R5TA, K472K15X7RH5TL2) are not compatible with 5.08mm or 5.00mm hole patterns without modification. Verify hole pattern compatibility before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the primary SR201C472KAATR2 part.
