SR075C223KAATR2 Equivalent & Substitute Parts

Part Overview

The SR075C223KAATR2 is a 0.022 µF ceramic capacitor rated at 50V 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 maintains Active product status with ROHS3 compliance and full REACH compliance.

Equivalent and substitute parts become necessary when the original part experiences supply constraints, lead time extensions, or when design flexibility permits component standardization across manufacturing batches. Substitute parts must maintain identical electrical specifications while accommodating variations in physical dimensions and lead configurations.

Substitute Part Grouping Explanation

Substitution validity for the SR075C223KAATR2 is determined by strict equivalence in the following electrical parameters: capacitance value (0.022 µF), tolerance (±10%), voltage rating (50V), and temperature coefficient (X7R). All substitute parts must maintain these specifications without deviation.

Physical dimensions and lead configurations may vary within the constraints of through-hole radial package standards. Lead spacing, lead style (formed kinked, formed straight, or straight), and overall component height are secondary parameters that permit substitution provided the component physically fits the PCB layout and does not create assembly conflicts.

All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence. Product status (Active or Not For New Designs) is noted for design planning purposes but does not disqualify electrical substitution.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the SR075C223KAATR2 across capacitance, tolerance, voltage rating, and temperature coefficient specifications. Selection among substitutes depends on PCB layout constraints and lead spacing requirements.

For designs with 2.54 mm lead spacing and compact footprints, C315C223K5R5TA (KEMET) provides direct dimensional compatibility with straight leads. For applications requiring 5.08 mm lead spacing, C322C223K5R5TA (KEMET) or SR215C223KAR (KYOCERA AVX) are suitable alternatives.

Vishay Beyschlag Mono-Kap™ K series parts (K223K10X7RF5UH5, K223K15X7RF5TH5, K223K15X7RF5TL2) offer high inventory availability and Active product status. Lead spacing varies between 2.50 mm and 5.00 mm, requiring PCB verification before substitution.

FK18X7R1H223KN020 (TDK Corporation) carries "Not For New Designs" status and should be reserved for legacy system maintenance or repair applications only.

All substitute parts carry ROHS3 compliance and REACH unaffected certification, maintaining regulatory equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can I substitute SR075C223KAATR2 with any of the listed parts without circuit redesign?

A: Electrical substitution is valid for all listed parts. Physical substitution requires verification that lead spacing and component height accommodate the PCB layout. Lead spacing variations (2.50 mm, 2.54 mm, 5.00 mm, 5.08 mm) must match or be compatible with existing PCB holes.

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

A: Lead style affects component insertion and retention during assembly. Formed kinked leads provide mechanical retention during manual insertion. Formed leads offer moderate retention. Straight leads require precise hole alignment and are typically used in automated assembly processes. All styles are electrically equivalent.

Q: Why do some parts show larger physical dimensions than the original?

A: Physical size variations reflect different package designations within the radial through-hole category. Larger packages (5.08 x 3.18 mm) accommodate higher current handling or different manufacturing processes but maintain identical electrical specifications. PCB layout must accommodate the selected package size.

Q: Is FK18X7R1H223KN020 suitable for new product designs?

A: No. FK18X7R1H223KN020 carries "Not For New Designs" status and should be used only for maintenance, repair, or legacy system support. For new designs, select from parts with Active product status.

Q: Do all substitute parts have the same inventory availability?

A: No. Inventory levels vary by part number and supplier. K223K10X7RF5UH5 (Vishay) shows 53,566 units in stock, while C317C223K5R5TA (KEMET) shows 1,783 units. Verify current availability with your supplier before design finalization.

Q: Are there any compliance or certification differences between substitute parts?

A: All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory profile. No compliance differentiation exists among the substitutes.
