SR201C223KAATR2 Equivalent & Substitute Parts

Part Overview

The SR201C223KAATR2 is a 0.022 µF ±10% 100V ceramic capacitor with X7R temperature coefficient manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is rated for general-purpose applications across an operating temperature range of -55°C to 125°C and carries ROHS3 compliance.

The SR201C223KAATR2 is currently active in production. Equivalent and substitute parts become necessary when the original part number is unavailable, when alternative packaging formats are required for manufacturing processes, or when lead spacing and form factor modifications are needed for specific PCB layouts.

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C223KAATR2 is determined by strict equivalence across the following parameters: capacitance value (0.022 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), and package type (radial). All substitute parts listed maintain these core electrical specifications.

Physical dimensions, lead spacing, and lead style variations are permitted substitution parameters, as these characteristics do not affect electrical performance but accommodate different PCB layout requirements and manufacturing processes. Packaging format differences (bulk, cut tape, tape and reel) are also acceptable substitution variables based on procurement and assembly workflow needs.

Engineering Selection Recommendations

For new designs and active production environments, prioritize parts with Active product status: SR201C223KAATR2, SR211C223KAA, SR201C223KARTR1 (KYOCERA AVX), C320C223K1R5TA, C322C223K1R5TA (KEMET), RDER72A223K0K1H03B, and RDER72A223K0M1H03A (Murata Electronics). All listed substitutes maintain ROHS3 compliance and identical electrical specifications.

When lead spacing of 0.100" (2.54mm) with straight leads is required, select SR201C223KAATR2, SR201C223KARTR1, or C320C223K1R5TA. When lead spacing of 0.200" (5.08mm) is required, select SR211C223KAA or C322C223K1R5TA. When lead spacing of 0.197" (5.00mm) is required, select RDER72A223K0K1H03B or RDER72A223K0M1H03A.

Parts marked "Not For New Designs" (TDK FK series) remain electrically equivalent but should be reserved for legacy system maintenance and repair applications only.

Frequently Asked Questions (FAQ)

Q: Can I substitute SR201C223KAATR2 with any of the listed parts?

A: Yes, all listed parts are electrically equivalent. Substitution is valid when the capacitance (0.022 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C) match. Physical differences in lead spacing and lead style do not affect electrical performance but must be compatible with your PCB layout.

Q: What is the difference between straight leads and formed leads?

A: Straight leads maintain their original orientation and are suitable for standard through-hole PCB layouts with 0.100" (2.54mm) spacing. Formed leads are pre-bent or kinked and accommodate different lead spacing requirements, such as 0.197" (5.00mm) or 0.200" (5.08mm), for alternative PCB designs.

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

A: Parts with "Not For New Designs" status indicate that the manufacturer has discontinued active production for new applications. These parts remain available for existing inventory and legacy system support but should not be selected for new product development. Use Active status parts for new designs.

Q: Does packaging format affect electrical performance?

A: No. Bulk, cut tape, and tape and reel packaging formats are logistics and assembly process variables only. They do not alter the electrical characteristics of the capacitor. Select packaging based on your manufacturing workflow requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original SR201C223KAATR2 specification.
