Substitute Part Grouping Explanation

Substitution of the LMK107BD7225MAHT is determined by strict equivalence across the following critical parameters:

Mandatory Match Criteria:

• Capacitance value: 2.2 µF (exact match required)
• Voltage rating: 10V (equal or higher acceptable)
• Temperature coefficient: X7T (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)
• Operating temperature range: -55°C ~ 125°C (equal or wider acceptable)

Acceptable Variation:

• Tolerance: ±20% or tighter (±10% is an acceptable upgrade)
• Ratings: AEC-Q200 compliance (required for automotive applications)
• RoHS and MSL status: Must maintain or exceed compliance level

The substitute part LMK107BD7225KAHT meets all mandatory criteria with an improved tolerance specification of ±10%, providing enhanced capacitance accuracy while maintaining all other electrical and mechanical characteristics.

The substitute part is available in higher inventory (8,134 pieces), supporting supply chain continuity. The tighter tolerance specification of the substitute part provides enhanced circuit performance without requiring any design modifications.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes. AEC-Q200 qualification is maintained across both parts, supporting automotive applications without additional qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can LMK107BD7225KAHT be used as a direct replacement for LMK107BD7225MAHT?

A: Yes. The LMK107BD7225KAHT is a direct substitute. Both parts share identical capacitance (2.2 µF), voltage rating (10V), temperature coefficient (X7T), package (0603), and operating temperature range (-55°C ~ 125°C). The substitute part features improved tolerance (±10% versus ±20%), which enhances circuit accuracy without requiring design changes.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal value. The LMK107BD7225MAHT allows capacitance to vary between 1.76 µF and 2.64 µF. The LMK107BD7225KAHT allows variation between 1.98 µF and 2.42 µF. Tighter tolerance (±10%) provides more predictable circuit behavior and is suitable for applications requiring higher capacitance accuracy.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the LMK107BD7225MAHT and LMK107BD7225KAHT carry AEC-Q200 automotive qualification, meeting automotive industry reliability and performance standards. Both parts are suitable for automotive and SMPS filtering applications.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts are packaged in 0603 (1608 Metric) surface mount format with identical physical dimensions (0.063" L x 0.031" W, 1.00mm maximum thickness). No PCB layout modifications are required for substitution.

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

A: This designation indicates that the manufacturer recommends evaluating alternative components for new product development. However, the part remains available for production support of existing designs. The substitute part LMK107BD7225KAHT carries the same status and is suitable for both existing and new applications.

Q: Are there any storage or handling differences between these parts?

A: No. Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling. Standard manufacturing and storage practices apply to both parts.

Q: What is the inventory status for these parts?

A: LMK107BD7225MAHT has 5,098 pieces in stock. LMK107BD7225KAHT has 8,134 pieces in stock. Both parts are available as new original components.
