Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 04025A2R4CAT2A are classified into two categories based on tolerance specifications:

Direct Equivalents (±0.25pF Tolerance): Parts with identical capacitance tolerance to the main part, ensuring equivalent performance in applications where ±0.25pF tolerance is acceptable. These parts are sourced from different manufacturers but maintain the same electrical and mechanical specifications.

Upgraded Alternatives (±0.1pF Tolerance): Parts with tighter tolerance specifications (±0.1pF) that provide enhanced precision. These parts are suitable for applications requiring stricter capacitance control and can be used as direct replacements with improved performance characteristics.

Key Parameters for Substitution:

• Capacitance value: 2.4 pF (exact match required)
• Voltage rating: 50V (minimum requirement)
• Temperature coefficient: C0G/NP0 (mandatory for temperature stability)
• Package: 0402 (1005 Metric) (physical compatibility requirement)
• Mounting type: Surface Mount, MLCC (assembly compatibility)
• Tolerance: ±0.25pF or tighter (electrical performance)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Tolerance): Select from 0402N2R4C500CT (Walsin), C0402C249C5GAC7867 (KEMET), CC0402CRNPO9BN2R4 (YAGEO), CL05C2R4CB5NNNC (Samsung), or CQ0402CRNPO9BN2R4 (YAGEO). All maintain ±0.25pF tolerance and are actively produced with full ROHS3 compliance and REACH unaffected status.

For Enhanced Precision: Select 04025A2R4BAT2A (KYOCERA AVX), CC0402BRNPO9BN2R4 (YAGEO), or CQ0402BRNPO9BN2R4 (YAGEO) for applications requiring ±0.1pF tolerance. These upgraded alternatives provide tighter capacitance control while maintaining all other electrical and mechanical specifications.

Avoid for New Designs: GRM1555C1H2R4CA01D (Murata) is marked "Not For New Designs" and should only be used for legacy system maintenance or repair applications.

Packaging Considerations: The main part 04025A2R4CAT2A is supplied in Tape & Reel format. Alternatives in Cut Tape format (04025A2R4BAT2A, CL05C2R4CB5NNNC) are suitable for lower-volume applications but may require different handling procedures.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±0.1pF tolerance in place of the original ±0.25pF part? A: Yes. Parts with ±0.1pF tolerance (04025A2R4BAT2A, CC0402BRNPO9BN2R4, CQ0402BRNPO9BN2R4) provide tighter tolerance and are fully compatible. They deliver improved precision without compromising circuit performance.

Q: Are all substitute parts in the same 0402 package? A: Yes. All listed substitutes use the 0402 (1005 Metric) surface mount package with identical dimensions (0.039" L x 0.020" W) and maximum thickness of 0.022" (0.55mm to 0.56mm), ensuring mechanical compatibility with the original design.

Q: What is the difference between C0G and NP0 temperature coefficients? A: C0G and NP0 designations are equivalent specifications for the same temperature coefficient characteristic. Both terms describe capacitors with negligible capacitance change across the -55°C to 125°C operating range. They are interchangeable in circuit applications.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance? A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical regardless of whether the part is supplied in Tape & Reel or Cut Tape format.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can I substitute GRM1555C1H2R4CA01D for new circuit designs? A: No. This part is marked "Not For New Designs" and should only be used for maintenance or repair of existing systems. For new designs, select from the actively produced alternatives listed in the Engineering Selection Recommendations section.
