Equivalent & Substitute Parts for Murata 50513AC Common Mode Choke

Part Overview

The Murata 50513AC is a 4-line common mode choke (CMC) designed for signal line filtering applications. This surface mount toroid component provides 51 µH inductance at 100 kHz with an 800 mA current rating and 168 mOhm maximum DC resistance. The part is actively manufactured and widely used in EMI suppression circuits for multi-conductor signal paths. Substitute parts are identified when identical electrical and mechanical specifications are maintained across the same product series.

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 50513AC is determined by strict equivalence across the following critical parameters:

• Inductance value: 51 µH @ 100 kHz
• Current rating: 800 mA maximum
• DC resistance: 168 mOhm maximum
• Number of lines: 4-line configuration
• Filter type: Signal line
• Mounting type: Surface mount
• Physical package: Horizontal, 4 gull wing
• Footprint dimensions: 6.00 mm x 7.10 mm length and width
• Height: 5.00 mm maximum
• Operating temperature range: -40°C to 125°C
• Series classification: 5000A

The Murata 50503AC meets all these criteria and is classified as a parametric equivalent within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 50513AC and 50503AC are active products manufactured by Murata Power Solutions Inc. within the 5000A series. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts may be based on inventory availability or procurement lead times, as they are functionally interchangeable for applications requiring 51 µH, 4-line common mode chokes with 800 mA current handling capability in surface mount horizontal gull wing packages. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 50503AC be used as a direct replacement for the 50513AC?

A: Yes. Both parts are parametric equivalents with identical inductance (51 µH @ 100 kHz), current rating (800 mA), DC resistance (168 mOhm), physical dimensions (6.00 mm x 7.10 mm x 5.00 mm), and package configuration (horizontal, 4 gull wing surface mount). They are interchangeable at the circuit level.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical ROHS3 compliance status, REACH unaffected designation, and MSL 1 moisture sensitivity rating. Both are actively manufactured.

Q: What determines substitution eligibility for this common mode choke?

A: Substitution is based on matching inductance value, current rating, DC resistance, number of lines (4), filter type (signal line), mounting method (surface mount), package style (horizontal gull wing), and physical footprint dimensions. All these parameters must remain constant.

Q: Can parts from other manufacturers substitute for the Murata 50513AC?

A: Substitution from other manufacturers would require verification that all electrical and mechanical parameters match exactly. The provided substitute list includes only Murata parts meeting these criteria.

Q: What is the significance of the 5000A series designation?

A: The 5000A series classification indicates the product family within Murata's common mode choke portfolio. Both substitute parts belong to this same series, confirming their design compatibility.
