Murata 82152C Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Murata 82152C is a 1.5 µH unshielded wirewound inductor rated for 1.4 A continuous current with a maximum DC resistance of 68 mOhm. This surface mount component in 1210 (3225 Metric) package is designed for applications requiring fixed inductance in compact form factors. The part is currently active in production and widely available. Substitute parts may be required due to inventory constraints, regional availability, or specific application performance requirements within the defined electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 82152C is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 1.5 µH (within ±20% tolerance specification)
• Shielding type: Unshielded
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 1.4 A minimum
• DC resistance: Substitute must not exceed 68 mOhm maximum
• Operating temperature range: Substitute must support minimum -40°C ~ 85°C
• Package dimensions: Physical compatibility with 1210 footprint or equivalent mechanical envelope

The Bourns SDR0302-1R5ML qualifies as a direct substitute based on matching inductance value, unshielded configuration, surface mount capability, and ROHS3 compliance. The substitute provides superior current rating (1.9 A vs. 1.4 A) and lower maximum DC resistance (70 mOhm vs. 68 mOhm), with extended operating temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 82152C and Bourns SDR0302-1R5ML are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts should be based on:

Murata 82152C: Primary choice when exact 1210 package footprint compliance is mandatory and current rating of 1.4 A is sufficient for the application.

Bourns SDR0302-1R5ML: Suitable alternative when higher current margin (1.9 A rating) provides design headroom or when extended operating temperature range (-40°C ~ 125°C) is required. Physical package dimensions must be verified for PCB layout compatibility due to nonstandard package classification.

Both parts maintain equivalent electrical performance within specified tolerances and regulatory compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0302-1R5ML be used as a direct replacement for the Murata 82152C?

A: Electrical substitution is valid based on matching inductance, tolerance, shielding, and compliance specifications. Physical package compatibility must be confirmed, as the Bourns part is classified as nonstandard package versus the standard 1210 (3225 Metric) footprint of the Murata part.

Q: What is the significance of the DC resistance difference (68 mOhm vs. 70 mOhm)?

A: The 2 mOhm difference falls within normal manufacturing variation for inductors in this category. Both values are acceptable for applications designed around the 68 mOhm maximum specification, with negligible impact on circuit performance.

Q: Does the higher current rating of the Bourns part affect circuit behavior?

A: No. The 1.9 A rating of the Bourns part provides additional design margin above the 1.4 A requirement. The inductor will perform identically in circuits designed for 1.4 A operation.

Q: Are there temperature-related considerations for substitution?

A: The Bourns part supports -40°C ~ 125°C operation versus -40°C ~ 85°C for the Murata part. For applications operating within -40°C ~ 85°C, both parts are equivalent. Applications requiring extended high-temperature operation benefit from the Bourns substitute.

Q: What packaging format is used for both parts?

A: Both parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes. Physical dimensions must be verified during PCB layout to ensure mechanical compatibility.
