Parameter Comparison

Engineering Selection Recommendations

The HMK105CG120JV-F serves as a direct parametric equivalent to the MSASH105SCG120JFNA01 for applications requiring identical electrical and mechanical specifications. Both parts are manufactured by Taiyo Yuden and maintain full compliance with ROHS3 and REACH requirements.

For Active Production and New Designs: The MSASH105SCG120JFNA01 is the preferred selection due to its Active product status, ensuring long-term availability and continued manufacturer support. This part is suitable for new circuit designs and production programs requiring component longevity assurance.

For Existing Designs and Inventory Management: The HMK105CG120JV-F is functionally equivalent and may be utilized as a substitute when the primary part is unavailable. However, this part carries a "Not For New Designs" designation, indicating it is in a mature or transitional phase of its product lifecycle. Use of this substitute is appropriate for legacy system maintenance, repair operations, or temporary supply chain solutions where electrical and mechanical compatibility is the primary requirement.

Both parts are suitable for general-purpose applications and maintain identical performance characteristics across the specified operating temperature range. Selection between these parts should be based on availability, supply chain strategy, and product lifecycle requirements rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can HMK105CG120JV-F be used as a direct replacement for MSASH105SCG120JFNA01 in existing circuit designs?

A: Yes. The HMK105CG120JV-F is a parametric equivalent with identical capacitance (12 pF), tolerance (±5%), voltage rating (100V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package dimensions (0402/1005 Metric). No circuit modifications or PCB layout changes are required for substitution.

Q: What is the significance of the "Not For New Designs" status on the HMK105CG120JV-F?

A: This designation indicates the part is in a mature phase of its product lifecycle and may have limited future availability or manufacturer support. For new product development, the MSASH105SCG120JFNA01 (Active status) is the recommended choice. The HMK105CG120JV-F remains suitable for repair, maintenance, and legacy system applications.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts share identical physical dimensions: 0.039" length x 0.020" width (1.00mm x 0.50mm) with a maximum thickness of 0.022" (0.55mm). They are both 0402 (1005 Metric) package designations and are fully compatible with the same PCB footprints and assembly processes.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the MSASH105SCG120JFNA01 and HMK105CG120JV-F are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). They meet the same environmental and regulatory standards for electronic component use.

Q: What is the difference in available inventory between these parts?

A: The MSASH105SCG120JFNA01 has 659 units in stock, while the HMK105CG120JV-F has 38,842 units available. Inventory levels may influence sourcing decisions when supply constraints exist, though both parts are currently available from stock.

Q: Can these parts be used interchangeably in high-reliability or aerospace applications?

A: Interchangeability is determined by the specific application requirements and qualification standards. Both parts meet identical electrical and mechanical specifications and carry the same compliance certifications. Application-specific qualification requirements should be evaluated based on the relevant industry standards and design specifications for the intended use.
