Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: capacitance value (470 pF), tolerance (±5%), voltage rating (200V minimum), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), mounting type (through hole), and package configuration (radial). All identified substitutes meet these core electrical and mechanical requirements.

The substitute parts are categorized as follows:

Direct Equivalents (Same Voltage Rating - 200V): C315C471J2G5TA, C317C471J2G5TA, C320C471J2G5TA, and C322C471J2G5TA (all KEMET GoldMax 300 Comm C0G series) provide direct functional equivalence with identical electrical specifications. These parts differ in physical dimensions and lead configurations.

Upgrade Option (Higher Voltage Rating - 250V): FK18C0G2E471JN020 (TDK Corporation FK series) exceeds the voltage requirement at 250V, providing enhanced voltage margin. This part is marked as "Not For New Designs" and represents a legacy option.

Engineering Selection Recommendations

For New Designs: Select from the KEMET GoldMax 300 Comm C0G series (C315C471J2G5TA, C317C471J2G5TA, C320C471J2G5TA, or C322C471J2G5TA). All are active products with ROHS3 compliance and identical electrical specifications to the primary part. Selection among these four should be based on mechanical fit requirements, specifically lead spacing (0.100" or 0.200") and physical dimensions.

For Space-Constrained Applications: C315C471J2G5TA offers the smallest footprint (0.150" L × 0.100" W, 0.183" seated height) with 0.100" lead spacing and straight leads.

For Existing Designs with Wider Lead Spacing: C317C471J2G5TA or C322C471J2G5TA accommodate 0.200" lead spacing with formed leads, suitable for PCB layouts designed for this configuration.

For Standard Footprint Compatibility: C320C471J2G5TA matches the original part's physical dimensions (0.200" L × 0.125" W) with 0.100" lead spacing and straight leads.

Legacy Applications Only: FK18C0G2E471JN020 (TDK FK series) is designated "Not For New Designs" and should be used only in existing designs requiring this specific part number. This part provides 250V rating, exceeding the 200V requirement.

Frequently Asked Questions (FAQ)

Q: Can C315C471J2G5TA be used as a direct replacement for SR142A471JART on existing PCBs?

A: C315C471J2G5TA is electrically equivalent but has different physical dimensions and lead configuration. The 0.100" lead spacing matches the original, but the smaller footprint (0.150" L × 0.100" W versus 0.200" L × 0.100" W) and straight leads (versus kinked leads) may require PCB layout verification. Mechanical fit must be confirmed before substitution.

Q: What is the difference between C317C471J2G5TA and C320C471J2G5TA?

A: Both are KEMET GoldMax 300 Comm C0G parts with identical electrical specifications. C317C471J2G5TA has 0.200" lead spacing with formed leads and 0.150" length. C320C471J2G5TA has 0.100" lead spacing with straight leads and 0.200" length. Selection depends on PCB hole spacing and lead style requirements.

Q: Why is FK18C0G2E471JN020 marked "Not For New Designs"?

A: FK18C0G2E471JN020 is a legacy TDK part. While it meets all electrical and compliance requirements with a 250V rating, KEMET GoldMax 300 Comm C0G series parts are recommended for new designs due to active product status and continued manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (C315C471J2G5TA, C317C471J2G5TA, C320C471J2G5TA, C322C471J2G5TA, and FK18C0G2E471JN020) are ROHS3 compliant and REACH unaffected, matching the compliance profile of SR142A471JART.

Q: Can I use a 250V-rated capacitor in a 200V application?

A: Yes. FK18C0G2E471JN020 is rated at 250V and can be used in applications requiring 200V. The higher voltage rating provides additional safety margin. However, this part is not recommended for new designs.

Q: What is the significance of lead spacing in capacitor selection?

A: Lead spacing determines PCB hole positioning. SR142A471JART and most substitutes use 0.100" spacing, but C317C471J2G5TA and C322C471J2G5TA use 0.200" spacing. PCB layout must accommodate the selected lead spacing to ensure proper mechanical fit and electrical connection.
