Substitute Part Grouping Explanation

Substitution of the Murata Power Solutions 84154C is permissible when the replacement component meets the following criteria:

Critical Electrical Parameters:

• Inductance value of 150 µH with ±10% tolerance
• Current rating equal to or greater than 250 mA
• DC resistance not exceeding 3.2Ohm maximum
• Unshielded configuration
• Operating temperature range of -40°C ~ 125°C or broader

Mechanical & Compliance Parameters:

• Surface mount package type
• Nonstandard package classification
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

The Bourns Inc. SDR0403-151KL meets these substitution criteria with equivalent inductance, higher current rating capability, and compatible thermal and compliance specifications.

Engineering Selection Recommendations

The Bourns Inc. SDR0403-151KL is qualified as a direct substitute for the Murata Power Solutions 84154C based on the following engineering criteria:

Electrical Compatibility: Both components provide 150 µH inductance with identical ±10% tolerance specifications. The Bourns substitute offers a current rating of 260 mA, which exceeds the 250 mA requirement of the primary part. DC resistance of 3.4Ohm maximum is within acceptable limits for applications designed for the 3.2Ohm specification.

Compliance & Certification: Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage protocols.

Thermal Performance: Identical operating temperature range of -40°C ~ 125°C ensures equivalent thermal performance across specified application environments.

Mechanical Compatibility: Both components utilize surface mount technology with nonstandard package configurations, maintaining footprint and assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0403-151KL be used as a direct replacement for the Murata 84154C in existing designs?

A: Yes. The substitute part meets all critical electrical parameters including inductance value, tolerance, current rating, and DC resistance specifications. Both components share identical operating temperature ranges and compliance certifications.

Q: What is the difference in DC resistance between the two parts?

A: The Murata 84154C specifies a maximum DC resistance of 3.2Ohm, while the Bourns SDR0403-151KL specifies 3.4Ohm maximum. This 0.2Ohm difference is within acceptable substitution limits for most applications and does not compromise electrical performance.

Q: Are there any package or footprint differences between these inductors?

A: Both components are classified as nonstandard packages and are designed for surface mount assembly. The Murata part measures 0.177" L x 0.130" W x 0.114" H (4.50mm x 3.30mm x 2.90mm), while the Bourns part measures 0.177" L x 0.157" W x 0.138" H (4.50mm x 4.00mm x 4.60mm). Length is identical; width and height differ slightly. Physical layout verification is required for space-constrained applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Murata 84154C and Bourns SDR0403-151KL are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) ratings, ensuring equivalent compliance with industry standards and manufacturing requirements.

Q: What is the current rating difference, and does it affect substitution?

A: The Murata part is rated for 250 mA, while the Bourns substitute is rated for 260 mA. The higher rating of the substitute part provides additional design margin and does not restrict substitution in applications designed for the primary component.
