SR075C472KAATR2 Equivalent & Substitute Parts

Part Overview

The SR075C472KAATR2 is a 4700 pF ceramic capacitor rated at 50V 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 currently active and in stock with 965 units available. Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging or lead configurations better suit assembly requirements, or when design flexibility across multiple qualified suppliers is required.

Substitute Part Grouping Explanation

Substitution eligibility for the SR075C472KAATR2 is determined by strict equivalence in the following parameters: capacitance value (4700 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), and package type (radial). All qualified substitutes maintain these core electrical specifications. Physical dimensions, lead spacing, lead style, and height may vary within acceptable mechanical tolerances for through-hole radial packages. Packaging format (bulk, cut tape) and inventory availability do not affect electrical substitutability. RoHS compliance status is noted for regulatory considerations but does not preclude substitution where applicable.

Engineering Selection Recommendations

For new designs and active production, select from parts with Active product status and ROHS3 compliance: C315C472K5R5TA, C317C472K5R5TA, K472K10X7RF5UH5, K472K15X7RF5TH5, K472K15X7RF5TL2, RDER71H472K0K1H03B, or RDER71H472K0P1H03B. These parts meet current regulatory requirements and are supported by manufacturers for ongoing supply.

For legacy designs or where existing inventory must be maintained, C316C472K5R5HA7301 is electrically equivalent but carries RoHS non-compliance status and should be evaluated against project requirements.

Parts FK18X7R1H472KN020 and FK28X7R1H472KN000 from TDK are marked "Not For New Designs" and should be used only for sustaining production of existing products where supply continuity is critical.

Lead spacing and lead style variations among substitutes accommodate different PCB layouts and assembly equipment. Verify mechanical fit within your specific board design before final selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR075C472KAATR2 with any of the listed parts?

A: Yes, all listed parts are electrically equivalent based on capacitance, tolerance, voltage rating, temperature coefficient, and operating temperature range. Physical dimensions and lead configurations differ; verify mechanical compatibility with your PCB layout and assembly process.

Q: What is the difference between the KEMET C315C, C316C, and C317C series?

A: All three KEMET parts (C315C472K5R5TA, C316C472K5R5HA7301, C317C472K5R5TA) are electrically identical 4700 pF 50V X7R capacitors. The primary differences are lead spacing (0.100" for C315C and C316C; 0.200" for C317C) and seated height. C316C is RoHS non-compliant. Select based on your PCB lead spacing requirement.

Q: Why are some parts marked "Not For New Designs"?

A: Parts designated "Not For New Designs" (FK18X7R1H472KN020, FK28X7R1H472KN000) indicate the manufacturer is phasing out these products. They remain available for sustaining existing products but should not be selected for new development. Use Active-status alternatives for new designs.

Q: Does lead style (formed vs. straight) affect electrical performance?

A: No. Lead style affects only mechanical assembly and PCB insertion. Formed leads (kinked or standard formed) and straight leads are both acceptable for through-hole radial packages. Select based on your assembly equipment and board design requirements.

Q: Are all substitutes RoHS3 compliant?

A: Most substitutes are ROHS3 compliant. C316C472K5R5HA7301 is RoHS non-compliant. Verify compliance requirements for your application before selection.

Q: What inventory levels should I consider?

A: K472K15X7RF5TH5 and K472K15X7RF5TL2 (Vishay) offer the highest inventory (32,577 and 29,200 units respectively). C315C472K5R5TA (KEMET) provides 5,536 units. Confirm availability with your supplier for production schedules.
