Substitute Part Grouping Explanation

Substitute parts for the 04021J1R1ABSTR are identified based on strict parametric equivalence. The substitution criteria are limited to the following parameters that must match exactly:

• Capacitance value: 1.1 pF
• Tolerance: ±0.05 pF
• Voltage rating: 100 V
• Package type: 0402 (1005 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• Compliance certifications: RoHS3, REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and are suitable for direct substitution without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Both the 04021J1R1ABSTR and 04021J1R1ABSTR\500 are active production parts from KYOCERA AVX with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and packaging configuration. The 04021J1R1ABSTR\500 variant currently has higher inventory levels (1695 pcs) compared to the standard 04021J1R1ABSTR (946 pcs). Both parts carry full RoHS3 compliance and REACH Unaffected status, meeting regulatory requirements for commercial and industrial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can 04021J1R1ABSTR\500 be used as a direct replacement for 04021J1R1ABSTR?

A: Yes. Both parts are parametric equivalents with identical capacitance (1.1 pF), tolerance (±0.05 pF), voltage rating (100 V), package type (0402), and operating temperature range (-55°C to 125°C). No circuit modifications or board layout changes are required.

Q: What does the "\500" designation indicate in the part number 04021J1R1ABSTR\500?
