Murata Power Solutions 30101AC Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 30101AC is a 97 nH shielded wirewound inductor rated for 36 A continuous current with a maximum DC resistance of 0.35 mOhm. This component is designed for surface mount applications requiring low inductance values with high current handling capability. The part is currently active in production and widely available in inventory.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting the same functional requirements for the application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30101AC is determined by the following critical parameters:

• Inductance value within ±20% tolerance (acceptable range: 77.6 nH to 116.4 nH)
• Current rating minimum of 36 A continuous
• DC resistance not exceeding 0.35 mOhm
• Surface mount package configuration
• Operating temperature range covering -40°C to 130°C
• RoHS3 compliance and MSL 1 rating

The TDK Corporation VLB7050HT-R09M meets these substitution criteria with a 90 nH inductance value (within the ±20% tolerance band), 36 A current rating, 0.27 mOhm DCR, and equivalent environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TDK VLB7050HT-R09M is qualified as a substitute for the Murata 30101AC based on the following factors:

Both components maintain ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and handling requirements. The substitute part delivers superior DC resistance performance at 0.27 mOhm compared to the 0.35 mOhm maximum of the original part, reducing resistive losses in the circuit. Saturation current performance is also enhanced at 64 A versus 41 A.

The primary design consideration is the shielding difference: the original part is shielded while the substitute is unshielded. Applications requiring electromagnetic shielding for noise immunity or regulatory compliance must account for this distinction. The operating temperature upper limit of the substitute is 125°C compared to 130°C for the original part; applications operating continuously above 125°C require the original Murata component.

Both parts are surface mount compatible with equivalent footprint dimensions and MSL handling requirements, supporting direct board-level substitution where shielding and temperature constraints are not limiting factors.

Frequently Asked Questions (FAQ)

Q: Can the TDK VLB7050HT-R09M be used as a direct replacement for the Murata 30101AC?

A: Direct substitution is possible when the application does not require electromagnetic shielding and operates within the -40°C to 125°C temperature range. The substitute part provides equivalent current handling and superior DC resistance performance.

Q: What is the inductance tolerance range for both parts?

A: Both the Murata 30101AC and TDK VLB7050HT-R09M carry ±20% inductance tolerance. The 30101AC nominal value of 97 nH produces an acceptable range of 77.6 nH to 116.4 nH. The substitute's 90 nH nominal value falls within this tolerance band.

Q: How does the shielding difference affect circuit performance?

A: The Murata 30101AC shielded design reduces electromagnetic radiation and susceptibility to external magnetic fields. The unshielded TDK substitute may exhibit increased EMI coupling in sensitive analog circuits or applications requiring FCC/CE compliance verification. Circuit-level testing is necessary to confirm performance equivalence in shielding-critical applications.

Q: Are the physical package dimensions compatible?

A: The Murata 30101AC measures 7.00 × 7.00 × 4.96 mm while the TDK VLB7050HT-R09M measures 6.80 × 6.70 × 5.00 mm. Both are surface mount 2-SMD packages with compatible footprints for standard PCB layouts, though the slight dimensional variation should be verified against specific board design constraints.

Q: What is the DC resistance advantage of the substitute part?

A: The TDK VLB7050HT-R09M provides 0.27 mOhm maximum DCR compared to 0.35 mOhm for the Murata part, representing a 23% reduction in resistive losses. This translates to lower heat generation and improved efficiency in high-current applications.

Q: Do both parts meet the same compliance standards?

A: Both components are ROHS3 compliant with MSL 1 (Unlimited) ratings and REACH unaffected status. Compliance certifications are equivalent, supporting use in regulated applications without additional qualification.
