Key Parameters

Substitute Part Grouping Explanation

Substitution of the VJ1206Y392MXCMP is determined by strict equivalence in the following parameters:

• Capacitance value: 3900 pF
• Tolerance: ±20%
• Voltage rating: 200V minimum
• Temperature coefficient: X7R
• Package footprint: 1206 (3216 Metric)
• Mounting technology: Surface Mount, MLCC
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The substitute part C1206C392M2RAC7800 from KEMET meets all these criteria. Physical dimensions and electrical performance remain compatible within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the VJ1206Y392MXCMP and C1206C392M2RAC7800 are active production components with ROHS3 compliance and MSL 1 rating, suitable for direct substitution in applications requiring 3900 pF at 200V with X7R stability. The KEMET substitute offers reduced thickness (0.88mm vs 1.70mm), which may provide design flexibility in space-constrained layouts. The Vishay part maintains a higher maximum operating temperature of 150°C compared to the KEMET substitute at 125°C; this difference is relevant only for applications requiring sustained operation above 125°C. Both components are available in active inventory and meet identical electrical and mechanical specifications for standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can C1206C392M2RAC7800 be used as a direct replacement for VJ1206Y392MXCMP?

A: Yes. Both parts share identical capacitance (3900 pF), tolerance (±20%), voltage rating (200V), temperature coefficient (X7R), and package footprint (1206). Electrical performance and PCB layout compatibility are equivalent.

Q: What is the difference in operating temperature range between these parts?

A: The VJ1206Y392MXCMP operates from -55°C to 150°C, while the C1206C392M2RAC7800 operates from -55°C to 125°C. For applications requiring sustained operation above 125°C, the Vishay part is specified. For standard operating ranges below 125°C, both parts are functionally equivalent.

Q: Does the thickness difference affect PCB assembly?

A: The KEMET substitute is thinner (0.88mm vs 1.70mm). This does not affect electrical compatibility but may provide layout advantages in height-constrained designs. Both parts use identical 1206 footprints and are compatible with standard surface mount assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both VJ1206Y392MXCMP and C1206C392M2RAC7800 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available?

A: VJ1206Y392MXCMP is supplied in Tape & Reel (TR) format. C1206C392M2RAC7800 is supplied in Cut Tape (CT) format. Packaging selection depends on assembly volume and handling requirements.
