SR075C222KAATR2 Equivalent & Substitute Parts

Part Overview

The SR075C222KAATR2 is a 2200 pF ceramic capacitor rated at 50V with X7R temperature coefficient, manufactured by KYOCERA AVX under the SkyCap® SR series. This through-hole radial 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 ROHS3 compliant.

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 allows for functionally identical components from different manufacturers. All substitute parts listed maintain the same electrical specifications and mechanical compatibility within defined parameters.

Substitute Part Grouping Explanation

Substitution validity for the SR075C222KAATR2 is determined by strict equivalence in the following electrical parameters: capacitance (2200 pF), tolerance (±10%), voltage rating (50V), and temperature coefficient (X7R). All substitute parts must maintain the operating temperature range of -55°C to 125°C and be through-hole radial components.

Mechanical variations in lead spacing, lead style (formed kinked, formed straight), physical dimensions, and height are permitted substitution variables. These variations do not affect electrical performance but may impact PCB layout and assembly processes. Packaging format (bulk, cut tape) and inventory availability are logistical considerations that do not affect functional equivalence.

Product status differences are noted where applicable. Parts marked "Not For New Designs" remain electrically equivalent but may have limited long-term availability.

Engineering Selection Recommendations

All listed substitute parts are electrically equivalent to the SR075C222KAATR2 and maintain full ROHS3 compliance and REACH unaffected status. Selection among substitutes should prioritize active product status for long-term design reliability.

For new designs, active parts are preferred: C322C222K5R5TA (KEMET), K222K10X7RF5UH5, K222K15X7RF5TH5, K222K15X7RF5TL2 (Vishay), and RDER71H222K0K1H03B, RDER71H222K0M1H03A, RDER71H222K0P1H03B (Murata). TDK parts FK18X7R1H222KN020 and FK28X7R1H222KN000 are marked "Not For New Designs" and should be used only for legacy system maintenance or when existing inventory constraints require their use.

Lead spacing and lead style variations must be evaluated against specific PCB layout requirements. The original SR075C222KAATR2 uses 0.100" lead spacing with kinked leads; substitutes with different spacing (0.098" or 0.197") require PCB redesign or manual lead bending during assembly.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly without PCB modification?

A: Direct substitution without PCB modification is limited to parts with matching lead spacing. The SR075C222KAATR2 uses 0.100" (2.54mm) lead spacing. Only FK18X7R1H222KN020 and K222K15X7RF5TL2 share similar compact spacing (0.098" and 0.098" respectively). Parts with 0.197" or 0.200" lead spacing require PCB layout changes or manual lead adjustment.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: Active parts are currently manufactured and supported for new designs with guaranteed long-term availability. Parts marked "Not For New Designs" are in mature or end-of-life phases with limited production and eventual discontinuation. For new product development, active parts ensure supply chain continuity.

Q: Are all these parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the SR075C222KAATR2.

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

A: No. Lead style is a mechanical characteristic that affects assembly handling and PCB insertion. Kinked leads provide pre-formed bends for standard radial component insertion. Straight leads (K222K15X7RF5TL2) require manual bending or specialized insertion equipment. Electrical performance is identical.

Q: Which substitute offers the highest inventory availability?

A: K222K10X7RF5UH5 from Vishay offers 52,281 pieces in stock, providing the largest available inventory among all listed substitutes.

Q: Can I mix different substitute parts in the same design?

A: Yes, provided all parts are used in circuit locations where their specific lead spacing and physical dimensions are compatible with the PCB layout. Mixing parts with different lead spacings requires careful PCB design to accommodate both configurations or selective use in different board areas.
