Key Parameters

Substitute Part Grouping Explanation

Substitution for the 04021JR55PBSTR is determined by the following critical parameters:

• Capacitance Value: 0.55 pF with tolerance ±0.02 pF
• Voltage Rating: Minimum 100 V
• Package: 0402 (1005 Metric) surface mount only
• Dielectric Type: Thin film construction for RF performance
• Temperature Range: -55°C to 125°C minimum
• Compliance: RoHS3 compliant, MSL 1 rated

Only components matching all these parameters across electrical and mechanical specifications qualify as direct substitutes. The thin film dielectric and RF characteristics are non-negotiable for circuit performance in the intended application.

Engineering Selection Recommendations

Component selection for the 04021JR55PBSTR should prioritize:

• Product Status Alignment: Both main and substitute parts maintain Active status, ensuring continued manufacturing support and supply chain stability.
• Compliance Verification: RoHS3 compliance and REACH Unaffected status are maintained across all equivalent options, meeting regulatory requirements for industrial and commercial applications.
• Certification Consistency: MSL 1 rating ensures unlimited shelf life and handling flexibility without moisture bake-out requirements.
• Electrical Performance: Thin film construction with RF, High Q, and Low Loss characteristics must be preserved to maintain circuit performance specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute a different capacitance value for the 04021JR55PBSTR?

A: No. The 0.55 pF capacitance value with ±0.02 pF tolerance is a critical specification. Alternative capacitance values will alter circuit performance and are not acceptable substitutes.

Q: Are different package sizes compatible with the 04021JR55PBSTR?

A: No. The 0402 (1005 Metric) package is the only acceptable form factor. Different package sizes will not fit the PCB footprint and are not compatible.

Q: Can I use a ceramic capacitor instead of this thin film capacitor?

A: No. The thin film dielectric type is essential for RF performance, high Q factor, and low loss characteristics. Ceramic capacitors have different electrical properties and are not suitable substitutes.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited moisture sensitivity, meaning the component does not require moisture bake-out before soldering and can be stored indefinitely under normal conditions without special handling.

Q: Does the operating temperature range affect substitution compatibility?

A: Yes. Any substitute must support the full -55°C to 125°C operating temperature range. Components with narrower temperature ranges are not acceptable.

Q: Is the Accu-P® series designation important for substitution?

A: Yes. The Accu-P® series designation indicates specific RF performance characteristics and construction standards. Substitutes must be from the same series to ensure equivalent electrical behavior.
