SR201C333KAATR2 Equivalent & Substitute Parts

Part Overview

The SR201C333KAATR2 is a 0.033 µF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KYOCERA AVX in 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 ROHS3 compliant and currently active in production. Equivalent and substitute parts are identified when manufacturers discontinue production lines, when lead times exceed project requirements, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR201C333KAATR2 is determined by strict equivalence in the following parameters: capacitance value (0.033 µF), tolerance (±10%), voltage rating (100V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), mounting type (through hole), and package configuration (radial). All identified substitute parts meet these core electrical requirements. Physical dimensions, lead spacing, and lead style may vary within acceptable mechanical tolerances for through-hole radial packages. Compliance certifications (ROHS3, REACH, EAR99) are maintained across all substitute options.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status except FK16X7R2A333KN020, which carries a "Not For New Designs" designation and should be reserved for legacy system maintenance or repair applications only. For new designs, select from SR211C333KAR (KYOCERA AVX), C320C333K1R5TA (KEMET), C322C333K1R5TA (KEMET), or RDER72A333K1M1H03A (Murata Electronics). All active alternatives are ROHS3 compliant and REACH unaffected. Lead spacing and lead style differences require PCB layout verification to ensure mechanical fit within the intended application. Parts with 0.100" lead spacing (SR201C333KAATR2, C320C333K1R5TA) are directly compatible with standard 0.1" grid layouts. Parts with 0.200" or 0.197" lead spacing (SR211C333KAR, C322C333K1R5TA, RDER72A333K1M1H03A) require PCB designs accommodating wider lead pitch.

Frequently Asked Questions (FAQ)

Q: Can SR211C333KAR replace SR201C333KAATR2 directly on the PCB? A: Electrical substitution is valid. However, SR211C333KAR has 0.200" lead spacing versus 0.100" on the original part. PCB layout compatibility must be verified before implementation.

Q: What is the difference between straight leads and formed leads? A: Straight leads maintain their original spacing and are suitable for standard 0.1" grid PCB layouts. Formed leads (kinked or standard formed) are pre-bent for wider lead spacing and require PCB designs with corresponding hole patterns.

Q: Is FK16X7R2A333KN020 suitable for new product designs? A: No. This part carries "Not For New Designs" status. It is available for legacy system support and repair applications only. Use active alternatives for new designs.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. All listed substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0060, matching the original part's regulatory status.

Q: What physical dimension variations exist among substitutes? A: Overall length ranges from 0.177" to 0.217", and seated height ranges from 0.197" to 0.290". Lead spacing varies from 0.098" to 0.200". Verify PCB layout compatibility for the selected substitute before procurement.

Q: Are KEMET GoldMax 300 Comm X7R parts electrically equivalent? A: Yes. C320C333K1R5TA and C322C333K1R5TA meet all electrical specifications. Selection between them depends on required lead spacing: 0.100" for C320C333K1R5TA or 0.200" for C322C333K1R5TA.
