MLASH105SCG090DFNA01 Equivalent & Substitute Parts

Part Overview

The MLASH105SCG090DFNA01 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) is packaged in 0402 (1005 Metric) form factor and is designated for medical and non-critical applications. The part maintains Active product status with 1108 units currently in stock.

Substitute parts become necessary when primary inventory is depleted, when supply chain constraints affect availability, or when design requirements permit selection from qualified alternative manufacturers. The HMK105CG090DV-F represents a parametrically equivalent alternative, though it carries a Not For New Designs status and is intended for general purpose applications rather than medical use.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLASH105SCG090DFNA01 is determined by strict alignment with the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Capacitance value: 9 pF
• Capacitance tolerance: ±0.5pF
• Voltage rating: 100V (minimum)
• Temperature coefficient: C0G/NP0
• Operating temperature range: -55°C to 125°C
• Package designation: 0402 (1005 Metric)
• Mounting type: Surface Mount MLCC

Compliance Requirements:

• RoHS3 compliance status
• Moisture Sensitivity Level 1 or better
• REACH unaffected status

The HMK105CG090DV-F meets all mandatory electrical and mechanical parameters. Both parts share identical capacitance, tolerance, voltage rating, temperature coefficient, operating temperature range, package form factor, and mounting type. Both maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status. The primary distinction lies in product lifecycle status and application classification.

Engineering Selection Recommendations

Primary Selection: MLASH105SCG090DFNA01

The MLASH105SCG090DFNA01 is the recommended selection for new designs and ongoing production. This part carries Active product status, indicating full manufacturer support and continued availability. It is specifically qualified for medical and non-critical applications, making it suitable for designs requiring medical-grade component certification. Current inventory of 1108 units supports immediate procurement requirements.

Alternative Selection: HMK105CG090DV-F

The HMK105CG090DV-F is electrically and mechanically equivalent to the primary part and maintains full compliance with RoHS3, REACH, and MSL requirements. However, this part carries Not For New Designs status, indicating the manufacturer has discontinued active development and support for this model. The HMK105CG090DV-F is classified for general purpose applications rather than medical use.

Selection of HMK105CG090DV-F is appropriate only in the following circumstances:

• Existing designs currently utilizing this part number require continued supply
• Application requirements do not mandate medical-grade qualification
• Design specifications explicitly permit general purpose component classification
• Inventory availability of the primary part is insufficient for project timelines

Both parts are manufactured by Taiyo Yuden and share identical electrical performance, mechanical dimensions, and regulatory compliance certifications. The choice between them is determined by product lifecycle requirements and application classification rather than technical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can HMK105CG090DV-F be used as a direct replacement for MLASH105SCG090DFNA01 in existing assemblies?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (9 pF), tolerance (±0.5pF), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and 0402 package dimensions. However, the HMK105CG090DV-F carries Not For New Designs status and is classified for general purpose rather than medical applications. Substitution is permissible only if the application does not require medical-grade component qualification.

Q: What does "Not For New Designs" status mean for the HMK105CG090DV-F?

A: This designation indicates that Taiyo Yuden has discontinued active development and support for this part number. The manufacturer no longer recommends this part for incorporation into new product designs. Existing designs currently using this part may continue to receive supply, but new designs should utilize the MLASH105SCG090DFNA01, which carries Active status.

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

A: Yes. Both parts are packaged in 0402 (1005 Metric) form factor with dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum thickness of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts designed for 0402 surface mount components.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both MLASH105SCG090DFNA01 and HMK105CG090DV-F are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). They meet identical regulatory and environmental requirements.

Q: What is the difference in application classification between these parts?

A: The MLASH105SCG090DFNA01 is qualified for medical and non-critical applications, indicating it meets medical-grade component standards. The HMK105CG090DV-F is classified for general purpose applications. If your design requires medical-grade component certification, the MLASH105SCG090DFNA01 is the appropriate selection.

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Substitution with a higher voltage rating is permissible from an electrical standpoint, as the part will operate safely at lower voltages. However, higher voltage rated capacitors typically have different physical dimensions or different capacitance values. Any substitute must maintain the identical 9 pF capacitance value, ±0.5pF tolerance, 0402 package form factor, and C0G/NP0 temperature coefficient to ensure circuit performance and PCB compatibility.

Q: What inventory status should I consider when selecting between these parts?

A: The MLASH105SCG090DFNA01 currently has 1108 units in stock, providing substantial availability for immediate procurement. The HMK105CG090DV-F has 978 units available. For time-sensitive projects, either part offers adequate inventory. For long-term supply planning, the MLASH105SCG090DFNA01 is preferable due to its Active product status.
