Substitute Part Grouping Explanation

Substitute parts for the MSASE042SCG040CWNA01 are identified based on strict electrical and mechanical parameter matching. The substitution logic requires exact alignment across the following critical parameters:

Electrical Parameters:

• Capacitance value: 4 pF (exact match required)
• Tolerance: ±0.25pF (exact match required)
• Voltage rating: 16V (minimum requirement; higher ratings acceptable)
• Temperature coefficient: C0G/NP0 (exact match required for stability)
• Operating temperature range: -55°C to 125°C (exact match required)

Mechanical Parameters:

• Package designation: 01005 (0402 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm) (exact match required)
• Maximum thickness: 0.009" (0.22mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (required)
• REACH Status: REACH Unaffected (required)

Substitute parts must satisfy all critical parameters to ensure direct interchangeability in circuit design and PCB assembly without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can KGU02ACG1C4R0CH be used as a direct replacement for MSASE042SCG040CWNA01 without circuit redesign?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical capacitance (4 pF), tolerance (±0.25pF), voltage rating (16V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package dimensions (01005/0402 Metric). Direct substitution is possible without circuit modification.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts conform to the 01005 (0402 Metric) package standard with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum thickness of 0.009" (0.22mm). PCB footprints and assembly processes are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MSASE042SCG040CWNA01 and KGU02ACG1C4R0CH are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance requirements are satisfied by both parts.

Q: What is the difference between these two equivalent parts?

A: The parts differ only in manufacturer (Taiyo Yuden versus KYOCERA AVX) and internal series designation (MSAS versus CU). All electrical parameters, mechanical specifications, package dimensions, and compliance certifications are identical.

Q: Can I mix these parts in the same production batch?

A: Yes. Both parts are surface-mount MLCCs with identical package specifications, tape and reel packaging, and handling requirements. They can be used interchangeably in the same assembly process.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate across the identical temperature range (-55°C to 125°C) and carry the same 16V voltage rating. Derating curves and operational limits are equivalent.

Q: What is the significance of the C0G/NP0 temperature coefficient for substitution?

A: C0G/NP0 designation indicates negligible capacitance change across the operating temperature range. Both parts maintain this specification, ensuring stable circuit performance across environmental conditions. This parameter is critical for substitution compatibility.

Q: Are the tolerance specifications identical?

A: Yes. Both parts carry ±0.25pF tolerance on the 4 pF capacitance value. This tolerance specification is identical and ensures equivalent circuit performance and predictability.
