Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Matching Criteria:

• Capacitance value: 3 pF (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Temperature Coefficient: C0G or NP0 (equivalent designations)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Voltage Rating: Equal to or greater than 16V
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Tolerance Consideration: Substitute parts with tolerance of ±0.1pF or ±0.25pF are acceptable, as both meet or exceed the precision of the original part.

Voltage Upgrade Path: All identified substitutes are rated at 50V, providing voltage margin above the original 16V specification. This upgrade path maintains full backward compatibility while improving circuit reliability margins.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

For new designs and production applications, select from parts with Active product status:

• 04025A3R0BAT2A (KYOCERA AVX) — Same manufacturer as original, ±0.1pF tolerance, 50V rating
• 04025A3R0CAT2A (KYOCERA AVX) — Same manufacturer as original, ±0.25pF tolerance, 50V rating
• C0402C309C5GAC7867 (KEMET) — Active status, ±0.25pF tolerance, 50V rating
• CC0402CRNPO9BN3R0 (YAGEO) — Active status, ±0.25pF tolerance, 50V rating
• CQ0402BRNPO9BN3R0 (YAGEO) — Active status, ±0.1pF tolerance, 50V rating
• C1005NP01H030C050BA (TDK Corporation) — Active status, extended operating temperature to 150°C

Conditional Substitutes (Not For New Designs / Obsolete):

The following parts meet all electrical and mechanical parameters but carry product status restrictions:

• C1005C0G1H030B050BA (TDK Corporation) — Not For New Designs status
• C1005C0G1H030C050BA (TDK Corporation) — Not For New Designs status
• GRM1555C1H3R0CA01D (Murata Electronics) — Not For New Designs status
• CL05C030CB5NNNC (Samsung Electro-Mechanics) — Obsolete status

These parts are suitable for legacy system maintenance and repair applications only.

Compliance Verification:

All substitute parts listed maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original part's regulatory and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 16V original part?

A: Yes. The 50V rating provides additional voltage margin and is fully backward compatible. The circuit will operate identically, with improved reliability margins. All substitute parts identified are rated at 50V.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. Both terms describe capacitors with negligible capacitance change across the operating temperature range. They are interchangeable.

Q: Are there tolerance differences between ±0.1pF and ±0.25pF substitutes?

A: Yes. Parts with ±0.1pF tolerance provide tighter capacitance control than ±0.25pF parts. Both tolerances are acceptable substitutes for the original ±0.25pF part. Select ±0.1pF variants when circuit design requires higher precision.

Q: Why are some substitute parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status are still electrically and mechanically compatible but are being phased out by manufacturers. Use these parts only for maintenance of existing systems. For new designs, select from parts with Active product status.

Q: Is the 0402 package dimension critical for substitution?

A: Yes. The 0402 (1005 Metric) package dimension is mandatory for substitution. All identified substitutes use this identical package form factor and are directly interchangeable on the PCB without layout modification.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored indefinitely without special humidity control and do not require baking before soldering.

Q: Can I substitute parts from different manufacturers?

A: Yes. All substitute parts listed meet identical electrical specifications (3 pF, 50V, C0G/NP0, 0402 package) and are fully interchangeable regardless of manufacturer. Cross-manufacturer substitution is standard practice when product status and compliance requirements are met.
