LMK107BJ105KAHT Equivalent & Substitute Parts

Part Overview

The LMK107BJ105KAHT is a 1 µF ±10% 10V ceramic capacitor manufactured by Taiyo Yuden in the 0603 (1608 Metric) surface mount package with X5R temperature coefficient. This component is rated for automotive applications under AEC-Q200 and operates across -55°C to 85°C. The part carries a "Not For New Designs" product status, necessitating identification of equivalent and substitute components for ongoing production and new design implementations.

Substitute Part Grouping Explanation

Substitution of the LMK107BJ105KAHT is determined by strict equivalence in the following parameters: capacitance (1 µF), tolerance (±10%), temperature coefficient (X5R), package format (0603/1608 Metric), mounting type (Surface Mount MLCC), operating temperature range (-55°C ~ 85°C), and automotive compliance (AEC-Q200).

Voltage rating serves as the primary differentiator among substitute parts. The main part operates at 10V rated voltage. Substitute parts with equal or higher voltage ratings (10V, 16V, 25V, 35V, 50V) are electrically compatible for applications requiring 10V or lower operating conditions. Parts with lower voltage ratings are not suitable substitutes.

Manufacturer variations between Taiyo Yuden and TDK Corporation are acceptable provided all electrical and mechanical parameters remain equivalent. Product status (Active vs. Not For New Designs) and packaging format variations (Tape & Reel vs. Cut Tape) do not affect functional substitutability but may impact procurement and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage rated capacitor as a substitute for the LMK107BJ105KAHT?

A: Yes. A capacitor rated at 16V, 25V, 35V, or 50V is electrically compatible in applications requiring 10V or lower operating voltage. The higher voltage rating provides additional safety margin and does not degrade performance in lower voltage applications.

Q: What is the difference between Taiyo Yuden and TDK Corporation parts in this list?

A: Both manufacturers produce equivalent 1 µF ±10% X5R 0603 ceramic capacitors with identical electrical and mechanical specifications. The primary differences are manufacturer identity and product status. TDK Corporation parts listed carry Active status, while many Taiyo Yuden alternatives carry Not For New Designs status.

Q: Are MCASL168SB5105KTNA01 and CGA3E2X5R1A105K080AA true direct replacements?

A: Yes. Both parts match the LMK107BJ105KAHT in all critical parameters: 1 µF capacitance, ±10% tolerance, 10V voltage rating, X5R temperature coefficient, 0603 package, and AEC-Q200 automotive compliance. MCASL168SB5105KTNA01 is from Taiyo Yuden with Active status. CGA3E2X5R1A105K080AA is from TDK Corporation with Active status.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect component performance?

A: No. Packaging format affects only procurement and handling logistics, not electrical or mechanical performance. Both Tape & Reel and Cut Tape & Digi-Reel formats deliver identical components with the same specifications.

Q: Why is the LMK107BJ105KAHT marked "Not For New Designs"?

A: This product status indicates the part is in mature or end-of-life phase. For new design implementations, select Active status alternatives such as MCASL168SB5105KTNA01 (Taiyo Yuden) or CGA3E2X5R1A105K080AA (TDK Corporation) at the same 10V rating, or any of the Active status parts at higher voltage ratings.

Q: Can I substitute a 10V rated part with the LMK107BJ105KAHT?

A: Yes, provided the substitute maintains all other specifications: 1 µF capacitance, ±10% tolerance, X5R temperature coefficient, 0603 package, and AEC-Q200 compliance. MCASL168SB5105KTNA01 and CGA3E2X5R1A105K080AA are direct 10V equivalents.

Q: What certifications and compliance standards apply to all listed parts?

A: All parts listed are AEC-Q200 rated for automotive applications, ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. ECCN classification is EAR99 for all parts.
