SR305C334KAA Equivalent & Substitute Parts

Part Overview

The SR305C334KAA is a 0.33 µF ±10% 50V ceramic capacitor manufactured by KYOCERA AVX in the SkyCap® SR series. This radial through-hole component is classified as Active and suitable for general-purpose applications. Identifying equivalent and substitute parts is necessary to ensure design flexibility, maintain supply chain continuity, and accommodate alternative sourcing when primary components are unavailable or when application requirements necessitate modified electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SR305C334KAA with the C330C334K1R5TA is permissible based on the following electrical and mechanical compatibility criteria:

Critical Matching Parameters:

• Capacitance: Both parts rated at 0.33 µF
• Tolerance: Both parts rated at ±10%
• Temperature Coefficient: Both parts rated as X7R
• Operating Temperature Range: Both rated -55°C ~ 125°C
• Mounting Type: Both are Through Hole radial components
• Lead Spacing: Both feature 0.200" (5.08mm) lead spacing
• Compliance: Both are ROHS3 Compliant and REACH Unaffected

Parameter Difference: The primary difference between these parts is the rated voltage: SR305C334KAA operates at 50V, while C330C334K1R5TA is rated for 100V. A higher voltage rating does not preclude substitution in applications operating below the lower rated voltage of the two parts. Both components meet all other functional and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the SR305C334KAA and C330C334K1R5TA are active, in-stock components with ROHS3 compliance and REACH unaffected status. The C330C334K1R5TA offers a higher voltage rating (100V vs. 50V), providing additional margin in circuits where voltage stress is a consideration. Both components are certified to equivalent regulatory standards. The choice between these parts should be determined by circuit voltage requirements, available inventory, and lead time considerations. The dimensional differences (length and width) are minor and within typical manufacturing tolerance bands for radial ceramic capacitors, though PCB footprint verification is recommended for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can the C330C334K1R5TA substitute for the SR305C334KAA? A: Yes. Both components share identical capacitance (0.33 µF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), mounting type (Through Hole radial), and lead spacing (0.200"). The C330C334K1R5TA has a higher voltage rating (100V vs. 50V), which is compatible with 50V applications.

Q: What are the differences in physical dimensions? A: The SR305C334KAA measures 0.300" L x 0.150" W (7.62mm x 3.81mm), while the C330C334K1R5TA measures 0.280" L x 0.160" W (7.11mm x 4.07mm). Both have the same maximum seated height of 0.360" (9.14mm). The lead spacing is identical at 0.200" (5.08mm) for both parts.

Q: Are there compliance differences between these parts? A: No. Both the SR305C334KAA and C330C334K1R5TA are ROHS3 Compliant and REACH Unaffected with equivalent regulatory status.

Q: What is the lead style difference? A: The SR305C334KAA has straight leads, while the C330C334K1R5TA has formed leads. Both are suitable for through-hole PCB insertion, though formed leads may provide enhanced mechanical retention during assembly.

Q: In what applications can these parts be used interchangeably? A: Both components are rated for general-purpose applications and can be used interchangeably in circuits operating at or below 50V where a 0.33 µF capacitor with X7R temperature stability is required.
