0805J0100333KXR Equivalent & Substitute Parts

Part Overview

The 0805J0100333KXR is a 0.033 µF ceramic capacitor manufactured by Knowles Syfer, rated at 10V with X7R temperature coefficient in 0805 (2012 Metric) surface mount package. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Alternative equivalent parts may be required due to inventory availability, lead time optimization, or application-specific voltage margin requirements while maintaining identical capacitance and tolerance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J0100333KXR is determined by the following critical parameters:

• Capacitance Value: Must be 0.033 µF (exact match required)
• Tolerance: Must be ±10% (exact match required)
• Temperature Coefficient: Must be X7R (exact match required)
• Package / Case: Must be 0805 (2012 Metric) (exact match required)
• Mounting Type: Must be Surface Mount, MLCC (exact match required)
• Operating Temperature Range: Must support -55°C ~ 125°C (exact match required)
• Voltage Rating: May exceed 10V (uprating permitted for enhanced margin)
• RoHS & Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part KGM21NR71H333KM from KYOCERA AVX meets all mandatory parameters with an upgraded voltage rating of 50V, providing additional design margin while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J0100333KXR and KGM21NR71H333KM are Active product status components with full ROHS3 compliance and MSL 1 rating. The primary distinction is the voltage rating differential: the substitute part provides 50V rating versus the original 10V specification. This uprating is electrically compatible and does not introduce any functional degradation. Both components maintain identical capacitance, tolerance, temperature coefficient, and operating temperature range. The substitute part exhibits reduced maximum thickness (1.00mm versus 1.30mm), which may provide layout advantages in space-constrained applications. Selection between these parts should be based on inventory availability, lead time requirements, and application voltage margin preferences.

Frequently Asked Questions (FAQ)

Q: Can KGM21NR71H333KM be used as a direct replacement for 0805J0100333KXR?

A: Yes. Both parts share identical capacitance (0.033 µF), tolerance (±10%), temperature coefficient (X7R), package (0805), and operating temperature range (-55°C ~ 125°C). The substitute part features a higher voltage rating (50V versus 10V), which is compatible with applications designed for 10V operation.

Q: What is the significance of the voltage rating difference?

A: The 50V rating on KGM21NR71H333KM provides additional voltage margin compared to the 10V specification of 0805J0100333KXR. This uprating does not affect capacitance or tolerance performance and is suitable for circuits operating at or below 10V.

Q: Are there any physical compatibility concerns?

A: Both parts use the 0805 (2012 Metric) package with nearly identical length and width (2.00mm x 1.25mm versus 2.01mm x 1.25mm). The substitute part is thinner (1.00mm versus 1.30mm maximum thickness), which may provide layout benefits without introducing any mounting or assembly issues.

Q: Do both parts meet the same compliance standards?

A: Yes. Both 0805J0100333KXR and KGM21NR71H333KM are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring equivalent environmental and regulatory compliance.

Q: What packaging formats are available for the substitute part?

A: KGM21NR71H333KM is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
