PMC0603-101 Equivalent & Substitute Parts

Part Overview

The PMC0603-101 is a ferrite bead manufactured by Bourns Inc., rated at 100 Ohms @ 100 MHz with a maximum current rating of 200mA and DC resistance of 300mOhm. This component is designed for single-line EMI suppression in 0603 (1608 Metric) surface mount applications. The PMC0603-101 is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution for the PMC0603-101 is determined by the following critical parameters:

Impedance @ Frequency: 100 Ohms @ 100 MHz (primary electrical specification)
Package / Case: 0603 (1608 Metric) (physical compatibility requirement)
Number of Lines: 1 (functional requirement)
Operating Temperature Range: -55°C ~ 125°C (environmental compatibility)
Mounting Type: Surface Mount (assembly compatibility)

Direct substitutes maintain identical impedance and current ratings. Parametric equivalents provide the same impedance at 100 MHz but may vary in current rating or DC resistance, requiring circuit-level validation. Alternative impedance values (80 Ohm, 120 Ohm) are listed as parametric equivalents for applications where impedance tolerance permits substitution.

Engineering Selection Recommendations

Direct Substitutes (100 Ohms @ 100 MHz, 200mA):

MG1608-101Y and ACML-0603-101-T are direct functional equivalents with active product status and ROHS3 compliance. MG1608-101Y offers lower DC resistance (250mOhm vs. 300mOhm), while ACML-0603-101-T provides the lowest DC resistance (200mOhm). Both are suitable for direct replacement in new designs.

MH1608-101Y provides superior performance with 3A current rating and 40mOhm DC resistance, supporting higher current applications while maintaining 100 Ohms impedance. This part is recommended for designs requiring increased current capacity.

Parametric Equivalents (100 Ohms @ 100 MHz, Higher Current):

2506031017Y0 (Fair-Rite) supports 400mA current rating with 150mOhm DC resistance, providing enhanced current handling and lower losses compared to the original specification.

Alternative Impedance Values (80 Ohm or 120 Ohm @ 100 MHz):

MG1608-121Y, MG1608-800Y, 2506031217Y0, 2506038007Y0, 74279261, and ACML-0603-800-T are available for applications where impedance tolerance permits deviation from 100 Ohms. These parts maintain 0603 package compatibility and operating temperature range.

All substitute parts listed are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance for new production.

Frequently Asked Questions (FAQ)

Q: Can MH1608-101Y replace PMC0603-101 directly?

A: Yes. MH1608-101Y maintains identical impedance (100 Ohms @ 100 MHz) and package (0603), with superior electrical performance (3A vs. 200mA current rating, 40mOhm vs. 300mOhm DCR). It is a direct functional replacement suitable for all applications requiring the original specification.

Q: What is the difference between direct substitutes and parametric equivalents?

A: Direct substitutes (MG1608-101Y, ACML-0603-101-T) match the original impedance and current rating exactly. Parametric equivalents (2506031017Y0, MG1608-121Y, MG1608-800Y) maintain the same impedance at 100 MHz but differ in current rating or DC resistance, requiring circuit validation before use.

Q: Are all substitute parts available in the same packaging?

A: All listed substitutes use 0603 (1608 Metric) surface mount packaging. Packaging format varies: most are supplied in Tape & Reel (TR), while ACML-0603-800-T is available in Cut Tape (CT). Verify packaging requirements with your procurement process.

Q: Why is the PMC0603-101 obsolete?

A: The PMC0603-101 is classified as obsolete by Bourns Inc. Active alternatives from Bourns (MG1608-101Y, MH1608-101Y) and other manufacturers provide equivalent or superior performance with current product status and regulatory compliance.

Q: Can I use an 80 Ohm or 120 Ohm ferrite bead instead of 100 Ohm?

A: Substitution with alternative impedance values (80 Ohm or 120 Ohm) is possible only if circuit design permits impedance tolerance. Verify EMI suppression performance requirements before selecting parts with different impedance ratings.

Q: What is the significance of RoHS3 compliance?

A: ROHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. The original PMC0603-101 is RoHS non-compliant. All active substitutes listed are ROHS3 compliant, meeting modern regulatory requirements for new designs and production.
