Substitute Part Grouping Explanation

The Vishay Cera-Mite 561R10TCCQ15 qualifies as a direct substitute based on the following critical parameters:

• Capacitance value: 15 pF (identical)
• Voltage rating: 1000V (1kV) (identical)
• Tolerance: ±5% (identical)
• Mounting type: Through Hole (identical)
• Package configuration: Radial, Disc (identical)
• Lead spacing: 0.252" (6.40mm) (identical)
• Physical dimensions: 0.252" Dia (6.40mm) (identical)
• Operating temperature range: -55°C to 105°C (identical)
• RoHS compliance: ROHS3 Compliant (identical)

The primary distinction is the temperature coefficient specification: the substitute part uses C0G/NP0 instead of N1500. Both temperature coefficients are within acceptable parameters for general-purpose applications and maintain the same operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Cera-Mite 561R10TCCQ15 is the recommended substitute for the obsolete 561R1DF0Q15. Both parts maintain identical electrical ratings, physical dimensions, and mounting characteristics. The substitute part offers the advantage of active product status with higher inventory availability (2981 pcs vs. 1112 pcs). Both parts are ROHS3 compliant and carry the same ECCN and HTSUS classifications, ensuring regulatory and compliance continuity. The temperature coefficient difference (C0G/NP0 vs. N1500) does not affect functional compatibility within the specified operating temperature range for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the 561R10TCCQ15 be used as a direct replacement for the 561R1DF0Q15?

A: Yes. Both parts share identical capacitance (15 pF), voltage rating (1000V), tolerance (±5%), operating temperature range (-55°C to 105°C), physical dimensions (0.252" diameter), lead spacing (0.252"), and mounting configuration (through-hole radial disc). The parts are electrically and mechanically interchangeable.

Q: What is the difference between N1500 and C0G/NP0 temperature coefficients?

A: Both are temperature coefficient classifications for ceramic capacitors. N1500 specifies a capacitance change of ±1500 ppm over the operating temperature range. C0G/NP0 specifies a capacitance change of 0 ±30 ppm over the operating temperature range. For general-purpose applications, both coefficients maintain stable performance across the -55°C to 105°C operating range.

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

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8532.24.0060) classifications, and are manufactured by the same supplier (Vishay Cera-Mite). The substitute part is REACH Unaffected while the original is REACH Affected, which may provide additional regulatory advantages.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts are radial disc capacitors with identical lead spacing (0.252" / 6.40mm) and physical diameter (0.252" / 6.40mm). No PCB layout modifications are required.

Q: Why is the original part obsolete?

A: The 561R1DF0Q15 has been discontinued by the manufacturer. The 561R10TCCQ15 represents the active equivalent within the Vishay Cera-Mite 561R series, ensuring continued availability and supply chain reliability.
