Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL31C271JGFNNNF are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 270 pF (exact match required)
• Temperature Coefficient: C0G/NP0 (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage Rating: 500V or higher (uprating permitted)
• Tolerance: ±5% or tighter (tighter tolerance acceptable)
• Physical Thickness: Variation permitted within 1206 package constraints

Substitute parts must maintain electrical equivalence and mechanical interchangeability on standard PCB layouts designed for 1206 ceramic capacitors.

Engineering Selection Recommendations

GRM31A5C2J271JW01D (Murata Electronics) - Direct Equivalent

This part qualifies as a direct equivalent substitute. It maintains all mandatory matching parameters including 270 pF capacitance, C0G/NP0 temperature coefficient, 1206 package, and operating temperature range. The voltage rating is uprated to 630V, which provides additional design margin. The part is Active status with full RoHS3 compliance and MSL 1 rating. Thickness is reduced to 0.039" (1.00mm), which is compatible with standard 1206 PCB layouts.

C3216C0G2J271J060AA (TDK Corporation) - Upgrade Substitute

This part qualifies as an upgrade substitute with voltage rating uprated to 630V. All mandatory parameters match the original specification. However, product status is Last Time Buy, indicating limited future availability. Thickness is further reduced to 0.030" (0.75mm), providing maximum PCB clearance. RoHS3 compliance and MSL 1 rating are maintained.

KGM31VCG2H271GU (KYOCERA AVX) - Direct Equivalent

This part qualifies as a direct equivalent substitute. It maintains all mandatory matching parameters including 270 pF capacitance, C0G/NP0 temperature coefficient, 1206 package, and 500V voltage rating matching the original specification. Tolerance is tighter at ±2% compared to the original ±5%, providing improved capacitance accuracy. Product status is Active with full RoHS3 compliance and MSL 1 rating. Thickness is 0.048" (1.22mm), within standard 1206 package constraints.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original CL31C271JGFNNNF?

A: Yes. Uprating the voltage specification is permitted for substitute parts. GRM31A5C2J271JW01D and C3216C0G2J271J060AA both feature 630V ratings compared to the original 500V rating. Higher voltage ratings provide additional design margin and do not affect electrical compatibility in circuits designed for 500V operation.

Q: What is the significance of the C0G/NP0 temperature coefficient?

A: C0G and NP0 designations are equivalent classifications indicating minimal capacitance change across the operating temperature range of -55°C to 125°C. All substitute parts maintain this specification, ensuring stable capacitance performance in temperature-sensitive applications.

Q: Are all substitute parts mechanically compatible with PCB layouts designed for the CL31C271JGFNNNF?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical footprint dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Physical thickness varies between 0.030" and 0.055", but all values are within standard 1206 package constraints and compatible with typical PCB assembly processes.

Q: What is the difference between ±5% and ±2% tolerance?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 270 pF value. ±5% tolerance allows deviation from 256.5 pF to 283.5 pF. ±2% tolerance (KGM31VCG2H271GU) allows deviation from 264.6 pF to 275.4 pF, providing tighter capacitance accuracy. Tighter tolerance is acceptable as a substitute for ±5% specifications.

Q: Why is C3216C0G2J271J060AA marked as Last Time Buy?

A: Last Time Buy status indicates that TDK Corporation has announced end-of-life for this part number. While currently available in inventory (4820 Pcs), future availability is limited. For long-term supply chain planning, GRM31A5C2J271JW01D (Murata) or KGM31VCG2H271GU (KYOCERA AVX) with Active status are recommended.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 Compliant, meeting environmental and hazardous substance restrictions. MSL rating of 1 (Unlimited) is maintained across all parts, indicating no moisture sensitivity limitations during storage and handling.

Q: Can I mix different substitute parts in the same production batch?

A: All substitute parts are electrically and mechanically equivalent for the 270 pF 500V C0G/NP0 1206 application. However, manufacturing best practices recommend using a single part number per production batch to maintain consistency in component sourcing and traceability documentation.
