Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SR212A331JAA is determined by the following critical parameters:

• Capacitance Value: 330 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating: 200V minimum (equal or higher acceptable)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Lead Spacing: 0.200" (5.08mm) preferred for direct PCB compatibility
• Compliance: ROHS3 Compliant (maintained across all substitutes)

The substitute parts are categorized as follows:

Direct Equivalents (C317C331J2G5TA, C322C331J2G5TA, C315C331J2G5TA): KEMET GoldMax 300 Comm C0G series parts matching all electrical specifications and 200V voltage rating. Physical dimensions vary within acceptable through-hole radial package constraints.

Upgrade Options (FK26C0G2J331JN000, FK28C0G2E331JN000): TDK Corporation FK series parts with higher voltage ratings (630V and 250V respectively) and identical electrical characteristics. These parts are marked "Not For New Designs" but remain functionally compatible for existing applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: Select from KEMET GoldMax 300 Comm C0G series substitutes (C317C331J2G5TA, C322C331J2G5TA, or C315C331J2G5TA). All three parts maintain active product status, ROHS3 compliance, and identical electrical specifications to the SR212A331JAA. C322C331J2G5TA provides the closest physical footprint match with 0.200" lead spacing and 0.200" L x 0.125" W dimensions. C317C331J2G5TA and C315C331J2G5TA offer reduced physical size with 0.150" L x 0.100" W dimensions, suitable for space-constrained layouts.

For Legacy or Maintenance Applications: TDK Corporation FK series parts (FK28C0G2E331JN000 at 250V or FK26C0G2J331JN000 at 630V) are functionally compatible despite "Not For New Designs" status. These parts provide higher voltage margins and are appropriate for existing circuit support where component replacement is necessary. Lead spacing tolerance (0.197" vs. 0.200") requires PCB verification for direct substitution.

Lead Spacing Consideration: C315C331J2G5TA features 0.100" lead spacing, differing from the standard 0.200" spacing of the SR212A331JAA. This part requires PCB layout verification before selection.

Frequently Asked Questions (FAQ)

Q: Can I substitute the SR212A331JAA with a higher voltage-rated part?

A: Yes. FK28C0G2E331JN000 (250V) and FK26C0G2J331JN000 (630V) are electrically compatible substitutes. Higher voltage ratings do not affect circuit operation in applications designed for 200V. Physical dimensions and lead spacing must be verified against PCB layout constraints.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations are equivalent specifications for the same temperature coefficient characteristic. Both terms describe zero temperature coefficient ceramic capacitors with identical performance across the -55°C to 125°C operating range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (KEMET and TDK) maintain ROHS3 compliance matching the original SR212A331JAA specification.

Q: What does "Not For New Designs" mean for TDK parts?

A: This designation indicates the manufacturer recommends these parts for legacy system support and maintenance only. They remain fully functional and compliant but are not recommended for new circuit development. KEMET GoldMax 300 Comm C0G series parts are preferred for new designs.

Q: Can I use C315C331J2G5TA as a direct replacement?

A: C315C331J2G5TA is electrically equivalent but features 0.100" lead spacing compared to the SR212A331JAA 0.200" spacing. PCB layout verification is required to confirm compatibility with existing through-hole pad patterns before substitution.

Q: What is the inventory status of substitute parts?

A: KEMET C317C331J2G5TA (13,380 pcs), C322C331J2G5TA (1,116 pcs), and C315C331J2G5TA (2,361 pcs) are in stock. TDK FK28C0G2E331JN000 (1,287 pcs) and FK26C0G2J331JN000 (1,328 pcs) are available. Original SR212A331JAA inventory is 832 pcs.
