The identical X7R temperature coefficient, 100V voltage rating, and 0805 package footprint enable direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the CGA4F2X7R2A222M085AE replace the HMJ212KB7222MDHT in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The CGA4F2X7R2A222M085AE is a direct substitute with identical capacitance (2200 pF), voltage rating (100V), temperature coefficient (X7R), package dimensions (0805), and compliance certifications (AEC-Q200, ROHS3).

Q: What is the significance of the "Not For New Designs" status on the HMJ212KB7222MDHT?

A: This designation indicates the Taiyo Yuden part has been superseded and is no longer recommended for new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. The CGA4F2X7R2A222M085AE with Active status is the recommended alternative for new designs.

Q: Are there any PCB layout or assembly considerations when substituting these parts?

A: No. Both parts share identical 0805 (2012 Metric) package dimensions, soft termination features, and surface mount characteristics. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the HMJ212KB7222MDHT and CGA4F2X7R2A222M085AE carry AEC-Q200 certification, qualifying them for automotive applications. Both maintain MSL 1 moisture sensitivity rating and ROHS3 compliance.

Q: What is the tolerance specification for these capacitors?

A: Both parts are specified with ±20% capacitance tolerance. This tolerance applies across the operating temperature range of -55°C to 125°C under X7R temperature coefficient characteristics.

Q: Are there inventory differences between these parts?

A: Current inventory shows 1049 pieces of HMJ212KB7222MDHT and 1047 pieces of CGA4F2X7R2A222M085AE available. Inventory levels are subject to change based on supply and demand conditions.
