Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 04023J2R2QBSTR is determined by the following critical parameters:

• Capacitance value: 2.2 pF (exact match required)
• Voltage rating: 25 V (minimum requirement)
• Package / Case: 0402 (1005 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount (assembly process compatibility)
• Operating temperature range: -55°C to 125°C (environmental compatibility)
• Series: Accu-P® (product line consistency)
• RoHS3 compliance (regulatory requirement)
• Moisture Sensitivity Level: 1 (handling and storage compatibility)

The substitute part 04023J2R2BBSTR meets all critical electrical and mechanical parameters, with the exception of tolerance specification, which differs from the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the 04023J2R2QBSTR and 04023J2R2BBSTR are active products manufactured by KYOCERA AVX within the Accu-P® series. Both parts maintain RoHS3 compliance and identical electrical ratings for voltage, capacitance value, and operating temperature range. The primary distinction is the tolerance specification: the main part features ±0.03 pF tolerance, while the substitute features ±0.1 pF tolerance. Selection between these parts should be based on the tolerance requirements of the specific application circuit. Both parts are suitable for RF and high-frequency applications requiring low loss and high Q performance in 0402 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can 04023J2R2BBSTR be used as a direct replacement for 04023J2R2QBSTR?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical capacitance (2.2 pF), voltage rating (25 V), package (0402), temperature range (-55°C to 125°C), and mounting type. The tolerance difference (±0.03 pF vs. ±0.1 pF) must be evaluated against circuit requirements.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable deviation from the nominal capacitance value. The 04023J2R2QBSTR offers tighter tolerance (±0.03 pF), suitable for precision RF circuits. The 04023J2R2BBSTR offers wider tolerance (±0.1 pF), acceptable for applications with less stringent capacitance accuracy requirements.

Q: Are both parts suitable for RF applications?

A: Yes. Both parts are specified with RF, High Q, and Low Loss features, making them suitable for RF and high-frequency circuit applications.

Q: Do both parts have the same physical dimensions?

A: Yes. Both parts are packaged in 0402 (1005 Metric) with identical dimensions: 0.039" L x 0.022" W (1.00mm x 0.55mm) and maximum seated height of 0.020" (0.50mm).

Q: Are there any compliance or regulatory differences?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
