Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1206J6300151KAT is determined by strict alignment of the following parameters:

• Capacitance value: 150 pF (exact match required)
• Voltage rating: 630V (minimum, equal or higher acceptable)
• Temperature coefficient: C0G/NP0 (required for stability)
• Package: 1206 (3216 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Compliance: AEC-Q200, ROHS3, REACH Unaffected

The identified substitute parts meet all mandatory electrical and mechanical parameters. Tolerance variations (±10% vs. ±5%) represent an upgrade in precision and do not prevent substitution in applications where the original tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the 1206J6300151KAT based on electrical and mechanical parameter alignment:

C1206C151JBGACAUTO (KEMET): This part offers improved tolerance (±5% vs. ±10%) and is designated for automotive applications within the SMD Auto C0G HV series. It maintains full AEC-Q200 compliance and ROHS3 certification. Thickness specification is 0.053" (1.35mm).

CGA5C4C0G2J151J060AA (TDK): This part from the CGA series provides ±5% tolerance with the thinnest profile at 0.030" (0.75mm), which may offer advantages in space-constrained designs. It maintains full AEC-Q200 compliance and ROHS3 certification.

Selection between these substitutes should be based on design requirements for tolerance precision, physical height constraints, and supplier availability. All three parts are active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can C1206C151JBGACAUTO replace 1206J6300151KAT directly? A: Yes. Both parts share identical capacitance (150 pF), voltage rating (630V), temperature coefficient (C0G/NP0), package (1206), and operating temperature range (-55°C to 125°C). The improved tolerance (±5%) is a specification upgrade that does not prevent substitution.

Q: What is the difference between ±10% and ±5% tolerance? A: Tolerance defines the allowable deviation from the nominal capacitance value. The ±5% tolerance in substitute parts represents tighter manufacturing control and is suitable for applications where the original ±10% tolerance is acceptable. No circuit redesign is required.

Q: Are all three parts automotive-qualified? A: Yes. All parts carry AEC-Q200 qualification and are designated for automotive applications.

Q: Does the thickness difference between parts affect compatibility? A: The 1206 package accommodates all three thickness specifications (0.063", 0.053", and 0.030"). Verify PCB footprint and assembly process requirements for your specific application. Thinner parts may offer advantages in height-constrained designs.

Q: Are all parts RoHS and REACH compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is MSL 1 rating? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. All three parts carry this rating, simplifying inventory and storage management.
