EMI8043MUTAG Equivalent & Substitute Parts

Part Overview

The EMI8043MUTAG is a 6-line common mode choke (CMC) surface mount component manufactured by onsemi, designed for signal line filtering with integrated TVS diode ESD protection. This part operates at 100mA maximum current with 6Ohm typical DC resistance and is rated for -40°C to 85°C operating temperature. The component is ROHS3 compliant and maintains active product status. Substitute parts may be required due to inventory constraints, design optimization for different line configurations, or package size considerations while maintaining equivalent electrical performance.

Substitute Part Grouping Explanation

Substitution of the EMI8043MUTAG is determined by the following critical parameters:

Electrical Equivalence Criteria:

Current Rating (Max): 100mA
DC Resistance (DCR) (Max): 6Ohm (Typ)
Operating Temperature: -40°C ~ 85°C
Features: TVS Diode ESD Protection
Filter Type: Signal Line

Mechanical Compatibility Criteria:

Mounting Type: Surface Mount
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Compliance Criteria:

RoHS Status: ROHS3 Compliant
Product Status: Active

Substitute parts are grouped by number of lines (2-line, 4-line, or 6-line configurations) and series designation (EMI80 or EMI81). Parts with identical electrical parameters but different line counts or package dimensions are considered parametric equivalents. Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical substitution but may impact procurement and handling.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting the regulatory requirements of the original EMI8043MUTAG. Selection between EMI80 and EMI81 series parts with matching line counts (EMI8043MUTAG to EMI8133MUTAG or EMI8143MUTAG) is based on available inventory and PCB layout constraints, as both series provide identical electrical performance at 100mA, 6Ohm DCR, and -40°C to 85°C operating range.

For applications requiring different line configurations, EMI8042MUTAG (4-line) and EMI8041MUTAG (2-line) from the EMI80 series, or EMI8142MUTAG and EMI8131MUTAG/EMI8141MUTAG from the EMI81 series, maintain electrical equivalence while reducing package footprint. Package dimensions vary between series; EMI80 series parts are slightly larger than EMI81 equivalents for the same line count.

Packaging format differences (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical performance. EMI8141MUTAG offers the highest inventory availability (36,856 pcs) among 2-line configurations.

Frequently Asked Questions (FAQ)

Q: Can EMI8043MUTAG be replaced with a different line count part?

A: Line count substitution is application-dependent. EMI8043MUTAG is a 6-line device. Substitution with 2-line (EMI8041MUTAG, EMI8131MUTAG, EMI8141MUTAG) or 4-line (EMI8042MUTAG, EMI8142MUTAG) parts requires circuit redesign to accommodate the reduced number of filtered lines. All maintain identical electrical parameters (100mA, 6Ohm DCR, -40°C to 85°C).

Q: What is the difference between EMI80 and EMI81 series parts?

A: EMI80 and EMI81 series parts are electrically equivalent across all specified parameters. Primary differences are package dimensions and inventory availability. EMI81 series parts are generally more compact. Both series are ROHS3 compliant and active products.

Q: Are EMI8133MUTAG and EMI8143MUTAG interchangeable with EMI8043MUTAG?

A: Yes. EMI8133MUTAG and EMI8143MUTAG are 6-line common mode chokes with identical electrical specifications (100mA, 6Ohm DCR, -40°C to 85°C, TVS Diode ESD Protection). Both are ROHS3 compliant and active products. Package dimensions differ slightly between series, requiring PCB layout verification.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format is a procurement and handling consideration only. EMI8141MUTAG (Cut Tape & Digi-Reel) and EMI8131MUTAG (Tape & Reel) are electrically identical 2-line devices with the same electrical specifications.

Q: Which substitute part has the best availability?

A: EMI8141MUTAG (2-line, EMI81 series, Cut Tape & Digi-Reel packaging) has the highest inventory at 36,856 pcs. For 6-line equivalents, EMI8133MUTAG offers 11,048 pcs availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (EMI8041MUTAG, EMI8042MUTAG, EMI8131MUTAG, EMI8133MUTAG, EMI8141MUTAG, EMI8142MUTAG, EMI8143MUTAG) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
