Murata Power Solutions 82102C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 82102C is a 1 µH unshielded wirewound inductor rated for 2 A continuous current with a maximum DC resistance of 58mOhm. This surface mount component in 1210 (3225 Metric) package is designed for applications requiring low inductance values with moderate current handling capability. The part is active in production and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Murata 82102C is determined by the following critical parameters:

• Inductance Value: Must be 1 µH with ±20% tolerance
• Current Rating: Minimum 2 A continuous current capability
• DC Resistance: Maximum 58mOhm to maintain thermal and efficiency characteristics
• Shielding Configuration: Unshielded construction
• Mounting Type: Surface mount technology
• Operating Temperature: Minimum range of -40°C to 85°C
• Compliance: ROHS3 compliant status

The Bourns SDR0302-1R0ML meets these substitution criteria with equivalent inductance, superior current rating (2.1 A), comparable DC resistance (60mOhm max), and extended operating temperature range (-40°C to 125°C). Both parts are unshielded wirewound inductors with surface mount configuration and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 82102C and Bourns SDR0302-1R0ML are active production components with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The Bourns substitute provides equivalent electrical performance with a higher current saturation rating (2.7 A) and extended maximum operating temperature to 125°C, offering additional design margin for thermal applications. DC resistance values are within acceptable tolerance (58mOhm vs 60mOhm max). Selection between these parts should be based on availability, cost, and specific thermal or current margin requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0302-1R0ML directly replace the Murata 82102C in existing designs?

A: Yes. Both parts share identical inductance (1 µH ±20%), equivalent current ratings (2 A minimum), comparable DC resistance specifications, and surface mount configuration. The Bourns part offers higher current capability and extended temperature range, making it functionally compatible.

Q: What are the package differences between these parts?

A: The Murata 82102C uses standard 1210 (3225 Metric) packaging with dimensions 3.20mm L × 2.50mm W × 2.30mm H. The Bourns SDR0302-1R0ML uses a nonstandard package with dimensions 3.00mm L × 2.80mm W × 2.80mm H. Physical footprint differences require PCB layout verification before substitution.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity levels are identical (MSL 1 - Unlimited). No compliance barriers exist for substitution.

Q: How do the DC resistance specifications compare?

A: The Murata part specifies 58mOhm maximum, while the Bourns substitute specifies 60mOhm maximum. This 2mOhm difference is within acceptable tolerance for most applications and does not significantly impact thermal performance or efficiency.

Q: What is the temperature operating range difference?

A: The Murata 82102C operates from -40°C to 85°C, while the Bourns SDR0302-1R0ML extends to -40°C to 125°C. The Bourns part provides additional thermal margin for high-temperature applications.
