Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Capacitance value: 330 pF
Tolerance: ±5%
Voltage rating: 100V minimum
Temperature coefficient: C0G or NP0
Operating temperature range: -55°C to 125°C minimum
Mounting type: Through Hole
Package type: Radial
Lead spacing: Mechanical compatibility with 0.100" or 0.200" spacing

Parts are grouped into three categories: direct manufacturer equivalents (same manufacturer, different packaging), parametric equivalents (same electrical specifications, different manufacturer), and manufacturer-recommended alternatives (cross-manufacturer substitutes with identical or superior specifications).

Engineering Selection Recommendations

Direct Manufacturer Equivalents (KYOCERA AVX): SR151A331JARTR1 and SR151A331JAR provide identical electrical and mechanical specifications to the primary part. SR151A331JARTR1 differs only in packaging format (Cut Tape versus Bulk), suitable for automated assembly environments. Both maintain Active product status and full ROHS3 compliance.

Active Cross-Manufacturer Substitutes: KEMET C315C331J1G5TA and C317C331J1G5TA, along with Murata RDE5C2A331J0K1H03B and RDE5C2A331J0S1H03A, meet all electrical specifications with Active product status. Mechanical variations in lead spacing and seated height require PCB layout verification. KEMET parts feature Low ESL characteristics. Murata parts are available in both Bulk and Cut Tape packaging.

Legacy Alternatives: TDK FK18C0G2A331JN020 and FK28C0G2A331JN000 carry "Not For New Designs" status. These parts maintain electrical equivalence but are restricted from new product development. Use only for legacy system maintenance or repair applications where original part sourcing is unavailable.

Frequently Asked Questions (FAQ)

Q: Can SR151A331JARTR1 replace SR151A331JAT in production? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: SR151A331JARTR1 is supplied in Cut Tape for automated pick-and-place assembly, while SR151A331JAT is supplied in Bulk. Verify your assembly process requirements before substitution.

Q: Are KEMET C315C331J1G5TA and C317C331J1G5TA interchangeable? A: Both are electrically equivalent to SR151A331JAT. However, they differ in lead spacing: C315C331J1G5TA uses 0.100" spacing (matching the original), while C317C331J1G5TA uses 0.200" spacing. PCB layout compatibility must be confirmed before use.

Q: Why are TDK FK series parts marked "Not For New Designs"? A: These parts are in legacy status and no longer recommended for new product development. They remain electrically equivalent but should only be used for repair or maintenance of existing systems where original parts are unavailable.

Q: What is the impact of different seated heights on PCB design? A: Seated height variations (0.150" to 0.236") affect component clearance and board layout. Verify that your PCB design accommodates the maximum seated height of the substitute part. Taller components may require additional clearance above the board surface.

Q: Can I use Murata RDE5C2A331J0S1H03A instead of RDE5C2A331J0K1H03B? A: Yes. Both are electrically identical Murata parts with identical specifications. The difference is packaging: RDE5C2A331J0S1H03A is supplied in Cut Tape, while RDE5C2A331J0K1H03B is supplied in Bulk. Lead spacing differs (0.098" versus 0.197"), requiring PCB layout verification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the environmental and regulatory requirements of the primary part.
