0805J2001P50CUT Equivalent & Substitute Parts

Part Overview

The 0805J2001P50CUT is a 1.5 pF ceramic capacitor manufactured by Knowles Syfer, designed for high-frequency applications including RF and microwave circuits. This surface-mount multilayer ceramic capacitor (MLCC) operates across a temperature range of -55°C to 125°C with a rated voltage of 200V and C0G/NP0 temperature coefficient characteristics. The part is currently active in production with 664 units in stock. Substitute parts are identified when design requirements allow for higher voltage ratings or improved tolerance specifications while maintaining identical capacitance values and package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J2001P50CUT is determined by the following critical parameters:

• Capacitance Value: Must remain 1.5 pF (exact match required)
• Temperature Coefficient: Must be C0G or NP0 (interchangeable designations for the same characteristic)
• Package / Case: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Physical Dimensions: Must match 0.079" L x 0.049" W (2.00mm x 1.25mm) and 0.051" (1.30mm) maximum thickness

Substitute parts may differ in:

• Voltage Rating: Higher voltage ratings are acceptable as they provide design margin without affecting circuit performance at lower operating voltages
• Tolerance: Tighter tolerance specifications are acceptable as they improve precision without compromising functionality
• Packaging Format: Different packaging configurations (e.g., Tape & Reel vs. Cut Tape) are acceptable for procurement flexibility

Parameter Comparison

Engineering Selection Recommendations

The 0805J2501P50HUT qualifies as a direct substitute for the 0805J2001P50CUT based on electrical and mechanical compatibility. Both parts are manufactured by Knowles Syfer, maintain identical capacitance values and package dimensions, and share the same C0G/NP0 temperature coefficient specification. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level).

The substitute part offers a 250V rated voltage compared to the 200V rating of the main part, providing increased voltage margin in applications where higher transient voltages may occur. The substitute also provides tighter tolerance (±0.05pF versus ±0.25pF), which may be beneficial in precision RF and microwave circuits requiring closer capacitance control.

Selection between these parts should be based on circuit voltage requirements, tolerance specifications, and packaging availability. Both parts support the full -55°C to 125°C operating temperature range and are suitable for RF, microwave, and high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the 0805J2501P50HUT replace the 0805J2001P50CUT in existing designs?

A: Yes. The substitute part maintains identical capacitance (1.5 pF), temperature coefficient (C0G/NP0), package dimensions (0805/2012 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (250V vs. 200V) and tighter tolerance (±0.05pF vs. ±0.25pF) are compatible with applications designed for the original part.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (250V substitute vs. 200V main part) and tolerance specification (±0.05pF substitute vs. ±0.25pF main part). All other electrical and mechanical parameters remain identical.

Q: Are there any packaging differences between these parts?

A: The main part is supplied in Cut Tape (CUT) format, while the substitute is supplied in Tape & Reel (TR) format. Both formats contain the same component and are suitable for different procurement and assembly workflows.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0805J2001P50CUT and 0805J2501P50HUT are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited). Both parts are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Which part should be selected for high-voltage applications?

A: The 0805J2501P50HUT with its 250V rating is appropriate for circuits operating at or near 200V. The 0805J2001P50CUT with 200V rating is suitable for applications with lower voltage requirements and adequate design margin below 200V.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum thickness of 0.051" (1.30mm). Both are 0805 (2012 Metric) package format and are mechanically interchangeable on PCBs designed for this package.
