Key Parameters

Substitute Part Grouping Explanation

Substitution for the OP32B683K201CT is determined by the following critical parameters:

• Package Size: 1210 (3.2mm × 1.6mm) — physical compatibility with PCB footprints
• Dielectric Material: X7R — ensures stable capacitance across the operating temperature range (-55°C to 125°C)
• Tolerance: ±10% — acceptable variation in capacitance value
• Capacitance Value: 0.068 µF (68 nF) — functional requirement for the circuit
• Voltage Rating: Minimum 200V — electrical safety and performance margin
• RoHS Compliance: ROHS3 Compliant — regulatory requirement
• Moisture Sensitivity: MSL 1 — handling and storage compatibility

The substitute part C1206F683K2RAC7800 from KEMET meets all these criteria and is classified as an active product with current availability.

Engineering Selection Recommendations

The C1206F683K2RAC7800 from KEMET is a direct functional substitute for the OP32B683K201CT. Selection is based on the following factors:

• Product Status: The KEMET part is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete Walsin component.
• Regulatory Compliance: Both parts are ROHS3 compliant and carry identical moisture sensitivity ratings, eliminating compliance concerns during substitution.
• Electrical Equivalence: Matching capacitance (0.068 µF), tolerance (±10%), dielectric type (X7R), and voltage rating (200V) ensure functional compatibility in the circuit.
• Physical Compatibility: Both components use standard 1210/1206 package footprints, which are mechanically interchangeable on PCBs designed for this form factor.

Frequently Asked Questions (FAQ)

Q: Can the C1206F683K2RAC7800 be used as a direct replacement for the OP32B683K201CT?

A: Yes. Both parts share identical electrical specifications (0.068 µF, ±10%, X7R, 200V) and are physically compatible in 1210/1206 package footprints. The KEMET part is actively manufactured and available.

Q: What is the difference between 1210 and 1206 package designations?

A: 1210 and 1206 refer to the same physical dimensions (3.2mm × 1.6mm) using different naming conventions. 1210 is the imperial designation, while 1206 is the metric equivalent (3216 Metric). These packages are mechanically and electrically interchangeable.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 ratings, and are suitable for identical applications. The KEMET part includes documented operating temperature specifications (-55°C to 125°C), which aligns with standard X7R dielectric performance.

Q: Why is the original part obsolete?

A: The OP32B683K201CT is no longer manufactured by Walsin Technology Corporation. The KEMET C1206F683K2RAC7800 provides equivalent functionality with the advantage of active production status and established supply chain availability.

Q: What should be considered when implementing this substitution in production?

A: Verify PCB footprint compatibility with the 1210/1206 package size. Confirm that the 200V rating meets or exceeds circuit voltage requirements. Both parts are MSL 1, so standard moisture control procedures apply during storage and assembly.
