Substitute Part Grouping Explanation

Substitution eligibility for the 04021J0R9PBSTR is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.9 pF (exact match required)
• Capacitance tolerance: ±0.02 pF (exact match required)
• Voltage rating: 100 V (minimum requirement; higher ratings acceptable)
• Package / Case: 0402 (1005 Metric) (exact match required for PCB compatibility)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 125°C (minimum requirement; wider ranges acceptable)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Only parts meeting all these criteria without deviation are considered parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

The 04021J0R9PBSTR maintains Active product status with full regulatory compliance across RoHS3 and REACH designations. Selection of equivalent parts should prioritize components with identical Active status to ensure long-term supply chain stability and manufacturing consistency.

All substitute candidates must maintain ROHS3 compliance and MSL 1 rating to preserve environmental and manufacturing process compatibility. The Accu-P® series designation indicates optimized RF performance characteristics; substitutes from this series are preferred to maintain circuit performance specifications.

Frequently Asked Questions (FAQ)

Q: What makes a part a true substitute for the 04021J0R9PBSTR?

A: A substitute must match the exact capacitance value (0.9 pF), tolerance (±0.02 pF), voltage rating (100 V), package type (0402 / 1005 Metric), and operating temperature range (-55°C to 125°C). All electrical and mechanical parameters must align without deviation.

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Yes. A capacitor rated for 100 V or higher voltage can function as a substitute, provided all other parameters remain identical. Higher voltage ratings do not compromise circuit functionality.

Q: Is the 0402 package size critical for substitution?

A: Yes. The 0402 (1005 Metric) package is a physical requirement for PCB assembly compatibility. Substitutes must use the identical package footprint.

Q: Does the Accu-P® series designation affect substitution eligibility?

A: The Accu-P® series indicates RF-optimized performance with high Q and low loss characteristics. While not a strict substitution requirement, maintaining this series designation ensures consistent RF performance in applications where these features are specified.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. This simplifies storage and handling compared to higher MSL ratings and should be maintained in substitute selection.
