SR075C333KAATR1 Equivalent & Substitute Parts

Part Overview

The SR075C333KAATR1 is a 0.033 µF ±10% 50V 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 maintains ROHS3 compliance.

The SR075C333KAATR1 is currently in active production status. Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable or when alternative lead configurations and package dimensions better suit specific PCB layout requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR075C333KAATR1 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.033 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50V (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in lead spacing, lead style, physical dimensions, and seated height are permissible provided the component maintains electrical equivalence and fits within the PCB layout constraints of the application.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical equivalence to the SR075C333KAATR1 and carry ROHS3 compliance certification. Selection among these alternatives depends on PCB layout constraints and lead configuration requirements.

Active Status Parts: C315C333K5R5TA, C317C333K5R5TA, C320C333K5R5TA, C322C333K5R5TA, K333K15X7RF5TH5, K333K15X7RF5TL2, RDER71H333K0K1H03B, and RDER71H333K0P1H03B are all in active production and suitable for new designs.

Legacy Status Part: FK28X7R1H333KN000 carries a "Not For New Designs" status and should be used only for maintenance, repair, or obsolescence mitigation in existing production lines.

Lead spacing variations (0.098", 0.100", 0.197", 0.200") and lead style differences (straight, formed, kinked) must be evaluated against specific PCB hole patterns and assembly requirements. Seated height variations range from 0.100" to 0.290" and should be verified for clearance in confined spaces or multi-layer board designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR075C333KAATR1 with any of the listed parts without circuit redesign?

A: Yes, all listed substitute parts are electrically equivalent. However, PCB layout verification is required to confirm that lead spacing, lead style, and seated height are compatible with existing hole patterns and component clearances.

Q: What is the difference between "Formed Leads - Kinked" and "Formed Leads"?

A: Both are pre-formed lead configurations. Kinked leads have an additional bend angle, while standard formed leads follow a simpler curve. Both styles are mechanically compatible with standard through-hole PCB designs, but the specific geometry may affect insertion force and board clearance.

Q: Why do some substitutes have different lead spacing values?

A: Lead spacing (0.098", 0.100", 0.197", 0.200") determines the distance between component leads on the PCB. The SR075C333KAATR1 uses 0.100" spacing. Substitutes with different spacing require PCB layout modifications or may not fit existing hole patterns. Verify lead spacing compatibility before substitution.

Q: Is FK28X7R1H333KN000 suitable for new product designs?

A: No. FK28X7R1H333KN000 carries a "Not For New Designs" status and should be reserved for legacy product support, repair, or supply chain contingency only. For new designs, select from the active status alternatives.

Q: Do all substitute parts meet the same compliance standards as the SR075C333KAATR1?

A: Yes. All listed substitutes are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications as the primary part.

Q: What is the impact of different seated heights on component placement?

A: Seated height ranges from 0.100" to 0.290" across the substitute list. Taller components may interfere with adjacent components, connectors, or enclosure clearances. Verify clearance in the specific application before selecting a substitute with a different seated height.
