Voltage Rating: 10V (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)

Mechanical Parameters:

Package Type: 0603 (1608 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Physical Dimensions: 0.063" L x 0.031" W; Thickness 0.035" max (exact match required)

Engineering Selection Recommendations

Parametric Equivalent (Same Manufacturer): The LMK107B7225KA-TR is a parametric equivalent manufactured by Taiyo Yuden with identical electrical and mechanical specifications. The only difference is packaging format (Tape & Reel vs. Cut Tape). This part carries the same "Not For New Designs" status as the primary part.

Active Alternatives (Recommended for New Designs): All remaining substitute parts are manufactured by active component suppliers (TDK Corporation, Samsung Electro-Mechanics, and Murata Electronics) and carry "Active" product status. These parts are suitable for new design implementations and provide long-term availability assurance.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing manufacturing and storage protocols.

Inventory Availability: GRM188R71A225KE15J (Murata Electronics) offers the highest inventory level at 1,930,873 pieces, followed by CL10B225KP8NNNC (Samsung Electro-Mechanics) at 15,473 pieces. These options provide supply chain resilience for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LMK107B7225KA-T with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical capacitance (2.2 µF), tolerance (±10%), voltage rating (10V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package type (0603), and physical dimensions. Direct substitution is permissible at the component level without circuit modification.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are packaging and delivery formats only. They do not affect electrical performance, mechanical fit, or circuit compatibility. Cut Tape is suitable for manual assembly and small-quantity orders. Tape & Reel is optimized for automated pick-and-place assembly and high-volume production. Selection depends on manufacturing process requirements, not component functionality.

Q: Why is the LMK107B7225KA-T marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status with the manufacturer. While existing inventory remains available, Taiyo Yuden does not recommend this part for new product development. For new designs, select from the "Active" status alternatives: C1608X7R1A225K080AC (TDK), CL10B225KP8NFNC or CL10B225KP8NNNC (Samsung), or GRM188R71A225KE15D or GRM188R71A225KE15J (Murata).

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the primary part. This ensures compatibility with environmental regulations and procurement requirements across all markets.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under normal storage conditions. No special moisture-control packaging or baking procedures are required prior to assembly. All listed parts share this MSL rating.

Q: Can I use these parts interchangeably in existing production?

A: Yes. All substitute parts meet identical electrical, mechanical, and compliance specifications. They are suitable for direct substitution in existing bill-of-materials (BOM) entries. Packaging format selection (Cut Tape vs. Tape & Reel) should align with your assembly equipment and production volume requirements.

Q: Which substitute part offers the best long-term availability?

A: GRM188R71A225KE15J (Murata Electronics) offers the highest inventory level and active product status, providing the strongest long-term supply assurance. This part is recommended for designs requiring extended production lifecycles or high-volume requirements.
