Electrical Parameters (Must Match Exactly):

• Capacitance: 2 pF
• Tolerance: ±0.25pF
• Voltage Rating: 25V
• Temperature Coefficient: C0G/NP0

Mechanical Parameters (Must Match Exactly):

• Package / Case: 01005 (0402 Metric)
• Physical Dimensions: 0.016" L x 0.008" W (0.40mm x 0.20mm)
• Thickness (Max): 0.009" (0.22mm)
• Mounting Type: Surface Mount, MLCC

Compliance Parameters (Must Match):

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

All identified substitute parts meet these criteria across different manufacturers, enabling direct functional and physical interchangeability in circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MSAST042SCG020CWNA01, KGM02ACG1E2R0CH, and KGU02ACG1E2R0CH—are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability, supply chain considerations, and manufacturer preference.

MSAST042SCG020CWNA01 (Taiyo Yuden): Primary part with 985 units in stock. Suitable for applications requiring Taiyo Yuden sourcing or existing supply agreements.

KGM02ACG1E2R0CH (KYOCERA AVX): Direct parametric equivalent with 19,270 units in stock. Designated for general purpose applications with equivalent performance characteristics.

KGU02ACG1E2R0CH (KYOCERA AVX): Direct parametric equivalent with 40,436 units in stock. Specified for RF, microwave, and high frequency applications with high Q and low loss characteristics. Highest inventory availability.

All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating. Selection should be based on application requirements, supply chain logistics, and inventory availability rather than electrical performance, as all three parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can KGM02ACG1E2R0CH or KGU02ACG1E2R0CH be used as direct replacements for MSAST042SCG020CWNA01?

A: Yes. Both KYOCERA AVX parts are direct substitutes. They match all electrical parameters (2 pF capacitance, ±0.25pF tolerance, 25V rating, C0G/NP0 temperature coefficient), mechanical specifications (01005 package, identical dimensions and thickness), and compliance certifications (ROHS3, REACH unaffected, MSL 1).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: capacitance value (2 pF), tolerance (±0.25pF), voltage rating (25V), temperature coefficient (C0G/NP0), operating temperature range (-55°C ~ 125°C), package type (01005/0402 Metric), physical dimensions (0.016" L x 0.008" W), maximum thickness (0.009"), and compliance status (ROHS3, REACH unaffected, MSL 1).

Q: Are there differences in application suitability between the substitute parts?

A: KGU02ACG1E2R0CH is specified for RF, microwave, and high frequency applications with high Q and low loss characteristics. KGM02ACG1E2R0CH and MSAST042SCG020CWNA01 are designated for general purpose applications. However, all three parts meet identical electrical and mechanical specifications, allowing use across application categories based on design requirements.

Q: Does package compatibility affect substitution?

A: No. All three parts use the identical 01005 (0402 Metric) package with matching physical dimensions (0.016" L x 0.008" W) and maximum thickness (0.009"). PCB footprints and reflow profiles are interchangeable.

Q: What is the significance of MSL 1 rating for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All three parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: How do compliance certifications affect part selection?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronics manufacturing in regulated markets. Compliance status is identical across all substitute options.
