Substitute Part Grouping Explanation

Substitution eligibility for the SR225E334MAT is determined by the following criteria:

Electrical Match: Capacitance value of 0.33 µF, tolerance of ±20%, voltage rating of 50V, and Z5U temperature coefficient are mandatory for functional equivalence.
Mechanical Compatibility: Through-hole radial mounting type with formed leads ensures PCB layout compatibility.
Compliance: ROHS3 compliance and REACH unaffected status maintain regulatory alignment.
Physical Constraints: Lead spacing and body dimensions must accommodate existing PCB footprints without requiring layout modifications.

All substitute parts listed below meet these core criteria. Variations in lead spacing (0.100", 0.200") and body dimensions (0.200" × 0.125" vs. 0.280" × 0.160") represent different case sizes within the radial family and require verification against specific PCB design constraints.

Engineering Selection Recommendations

C320C334M5U5TA (KEMET GoldMax 300 Comm Z5U): Electrical specifications match the SR225E334MAT exactly. Body dimensions and height are compatible. Lead spacing of 0.100" differs from the main part's 0.250" spacing; straight lead style requires verification against PCB hole pattern. ROHS3 compliant and REACH unaffected. Suitable for applications where PCB footprint accommodates 0.100" lead spacing.

C322C334M5U5TA (KEMET GoldMax 300 Comm Z5U): Direct electrical and mechanical equivalent with matching body dimensions (0.200" × 0.125"), lead spacing (0.200"), and formed lead style. Height seated maximum of 0.260" is within acceptable tolerance. ROHS3 compliant and REACH unaffected. Highest compatibility for direct substitution in existing designs.

C322C334M5U5TA7301 (KEMET GoldMax 300 Comm Z5U, Cut Tape): Identical electrical and mechanical specifications to C322C334M5U5TA. Packaging format is Cut Tape (CT) rather than Bulk, affecting supply chain logistics but not component performance. ROHS3 compliant and REACH unaffected. Suitable for applications requiring tape-and-reel format.

C330C334M5U5TA (KEMET GoldMax 300 Comm Z5U): Electrical specifications match the SR225E334MAT. Body dimensions are larger (0.280" × 0.160") with increased height (0.360" maximum). Lead spacing of 0.200" differs from the main part. ROHS3 compliant and REACH unaffected. Suitable only for applications with PCB space available for larger case size.

Frequently Asked Questions (FAQ)

Q: Can C320C334M5U5TA replace SR225E334MAT directly on the PCB?

A: C320C334M5U5TA matches all electrical specifications. However, lead spacing is 0.100" versus the main part's 0.250", and leads are straight rather than formed. PCB hole pattern must accommodate this difference. Verify footprint compatibility before substitution.

Q: What is the difference between C322C334M5U5TA and C322C334M5U5TA7301?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: C322C334M5U5TA is supplied in Bulk format, while C322C334M5U5TA7301 is supplied in Cut Tape (CT) format. Component performance is equivalent.

Q: Is C330C334M5U5TA a suitable substitute for SR225E334MAT?

A: C330C334M5U5TA meets all electrical requirements. Body dimensions are larger (0.280" × 0.125" versus 0.200" × 0.125"), and height is increased to 0.360" maximum. Substitution is valid only if PCB layout accommodates the larger case size and 0.200" lead spacing.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (C320C334M5U5TA, C322C334M5U5TA, C322C334M5U5TA7301, C330C334M5U5TA) are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the SR225E334MAT.

Q: What is the critical parameter for substitution eligibility?

A: Capacitance (0.33 µF), voltage rating (50V), temperature coefficient (Z5U), and tolerance (±20%) are mandatory electrical parameters. Lead spacing and body dimensions must be verified against PCB design constraints to ensure mechanical compatibility.
