MSASH105SCG090DFNA01 Equivalent & Substitute Parts

Part Overview

The MSASH105SCG090DFNA01 is a 9 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 100V with C0G/NP0 temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 0402 package format is designed for general-purpose applications requiring stable capacitance across temperature variations. The part is currently in Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when primary inventory is unavailable, when design revisions require alternative sourcing, or when supply chain optimization requires qualified alternatives from the same manufacturer.

Substitute Part Grouping Explanation

Substitution of the MSASH105SCG090DFNA01 is based on strict electrical and mechanical parameter matching. The following parameters must remain identical across all qualified substitutes:

• Capacitance Value: 9 pF (exact match required)
• Capacitance Tolerance: ±0.5pF (exact match required)
• Voltage Rating: 100V (minimum acceptable rating)
• Temperature Coefficient: C0G/NP0 (ensures frequency and temperature stability)
• Package Format: 0402 (1005 Metric) (physical footprint compatibility)
• Mounting Technology: Surface Mount MLCC (assembly compatibility)
• Operating Temperature Range: -55°C ~ 125°C (environmental specification)
• Regulatory Compliance: RoHS3 Compliant (mandatory for regulated applications)

The HMK105CG090DV-F qualifies as a parametric equivalent substitute because it matches all critical electrical specifications and physical requirements. The primary distinction is product status: the MSASH105SCG090DFNA01 is Active, while the HMK105CG090DV-F is designated Not For New Designs, indicating it remains available for existing designs but should not be selected for new development.

Parameter Comparison

Engineering Selection Recommendations

For Active Development and New Designs: The MSASH105SCG090DFNA01 is the primary selection. This part carries Active product status, indicating full manufacturer support, continued availability, and suitability for new circuit designs. Current inventory of 669 pieces supports production requirements.

For Existing Design Maintenance and Replacement: The HMK105CG090DV-F qualifies as a direct parametric substitute for the MSASH105SCG090DFNA01 in applications where the original part becomes unavailable. Despite Not For New Designs status, this part maintains identical electrical and mechanical specifications, RoHS3 compliance, and REACH unaffected status. The 978-piece inventory provides adequate supply for legacy system support and field replacements.

Compliance Verification: Both parts satisfy RoHS3 compliance requirements and carry REACH unaffected status, making them suitable for regulated markets and applications with environmental compliance mandates. MSL 1 rating (Unlimited) eliminates moisture sensitivity concerns during storage and handling.

Substitution Constraints: Substitution is valid only when all parameters listed in the Key Parameters table remain unchanged. Any deviation in capacitance value, tolerance, voltage rating, temperature coefficient, or package format invalidates the substitution relationship.

Frequently Asked Questions (FAQ)

Q: Can the HMK105CG090DV-F be used as a direct replacement for the MSASH105SCG090DFNA01 in existing circuit boards?

A: Yes. The HMK105CG090DV-F is a parametric equivalent with identical capacitance (9 pF), tolerance (±0.5pF), voltage rating (100V), temperature coefficient (C0G/NP0), package format (0402), and operating temperature range (-55°C ~ 125°C). Physical dimensions and mounting characteristics are identical, enabling direct substitution in existing PCB layouts without design modification.

Q: Why is the HMK105CG090DV-F marked as "Not For New Designs" if it is electrically equivalent?

A: Product status reflects manufacturer lifecycle management and long-term availability strategy. "Not For New Designs" indicates the part remains available for existing applications and field replacements but should not be selected for new circuit development. The MSASH105SCG090DFNA01, with Active status, is the recommended choice for new designs to ensure extended product lifecycle support.

Q: Are there any differences in reliability or failure rate between these two parts?

A: Both parts are manufactured by Taiyo Yuden and share identical electrical specifications, temperature coefficients, and compliance certifications. No failure rate data is provided in the technical specifications for either part. Reliability characteristics are determined by application conditions, thermal cycling, voltage stress, and manufacturing process consistency rather than part number designation.

Q: What is the significance of the 0402 package format for substitution purposes?

A: The 0402 (1005 Metric) package format is a critical substitution parameter. This designation specifies the physical footprint (0.039" L x 0.020" W / 1.00mm x 0.50mm), maximum thickness (0.022" / 0.55mm), and surface-mount pad configuration. Both substitute parts maintain identical 0402 specifications, ensuring compatibility with existing PCB designs, pick-and-place equipment programming, and reflow soldering profiles without modification.

Q: How does the C0G/NP0 temperature coefficient affect substitution decisions?

A: C0G (Ceramic 0 ppm/°C) and NP0 (Negative-Positive 0 ppm/°C) are equivalent designations for temperature-stable ceramic capacitors with minimal capacitance drift across the -55°C ~ 125°C operating range. This specification is critical for frequency-determining circuits, timing applications, and RF tuning networks. Both the main part and substitute maintain this specification, ensuring circuit performance stability across temperature variations.

Q: What is MSL 1 (Unlimited) and why does it matter for component substitution?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This eliminates the need for dry-pack storage, desiccant bags, or bake-out procedures before assembly. Both the MSASH105SCG090DFNA01 and HMK105CG090DV-F carry MSL 1 rating, making them interchangeable from a moisture management perspective.

Q: Are both parts RoHS3 compliant and suitable for regulated markets?

A: Yes. Both the MSASH105SCG090DFNA01 and HMK105CG090DV-F are ROHS3 Compliant and carry REACH Unaffected status. This certification confirms compliance with European Union Restriction of Hazardous Substances directives and indicates no restricted substances are present. Both parts are suitable for applications requiring environmental compliance in regulated markets including automotive, medical, and industrial sectors.
