PMC0805-601 Equivalent & Substitute Parts

Part Overview

The PMC0805-601 is a ferrite bead component manufactured by Bourns Inc., designed for electromagnetic interference (EMI) suppression in single-line applications. This component operates at 600 Ohms impedance at 100 MHz with a maximum current rating of 100mA and 1 Ohm DC resistance. The PMC0805-601 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Active alternatives from Bourns Inc. provide enhanced specifications while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the PMC0805-601 is determined by the following critical parameters:

Mandatory Matching Parameters:

Impedance @ 100 MHz: 600 Ohms
Package / Case: 0805 (2012 Metric)
Number of Lines: 1
Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
Mounting Type: Surface Mount

Allowable Parameter Variations:

Current Rating (Max): Substitute parts must equal or exceed 100mA
DC Resistance (Max): Substitute parts must not exceed 1 Ohm (lower values are acceptable)
Product Status: Active alternatives are preferred over obsolete parts
RoHS Compliance: ROHS3 compliant alternatives are preferred

All three substitute parts (MH2029-601Y, MZ2029-601T, MZ2029-601Y) meet the mandatory matching parameters and are therefore valid equivalents for the PMC0805-601.

Engineering Selection Recommendations

MH2029-601Y is the primary substitute for PMC0805-601. This part is active, ROHS3 compliant, and provides superior electrical performance with 1A current rating and 200mOhm DC resistance. The enhanced current capacity and reduced DC resistance make this the optimal choice for new designs. Packaging is available in Cut Tape and Digi-Reel formats.

MZ2029-601T and MZ2029-601Y are secondary substitutes, both active and ROHS3 compliant. MZ2029-601T supports 200mA current rating with 400mOhm DC resistance, while MZ2029-601Y matches the original 100mA current rating with 400mOhm DC resistance. Both are supplied in Tape & Reel packaging. These alternatives are suitable when MH2029-601Y availability is constrained or when specific packaging requirements necessitate the MZ series.

All three substitutes exceed or match the original PMC0805-601 specifications while offering active product status and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MH2029-601Y, MZ2029-601T, or MZ2029-601Y be used as direct replacements for PMC0805-601?

A: Yes. All three parts maintain identical impedance (600 Ohms @ 100 MHz), package format (0805 / 2012 Metric), operating temperature range (-55°C ~ 125°C), and single-line configuration. The substitute parts meet or exceed the original current and DC resistance specifications.

Q: What are the key differences between the three substitute options?

A: MH2029-601Y provides the highest current rating (1A) with the lowest DC resistance (200mOhm). MZ2029-601T supports 200mA with 400mOhm DC resistance. MZ2029-601Y matches the original 100mA current rating with 400mOhm DC resistance. Selection depends on application current requirements and available packaging formats.

Q: Are there height or dimensional differences that affect PCB layout?

A: The PMC0805-601 has a maximum height of 0.035" (0.90mm), while all three substitutes have a maximum height of 0.043" (1.10mm). Width dimensions are also slightly reduced in the substitutes (0.047" vs. 0.049"). These minor variations are within standard 0805 package tolerances and do not typically require PCB layout modifications.

Q: What is the regulatory compliance status of the substitute parts?

A: All three substitute parts are ROHS3 compliant, whereas the PMC0805-601 is RoHS non-compliant. This compliance improvement is significant for applications subject to RoHS regulations.

Q: Which packaging format should be selected?

A: MH2029-601Y is available in Cut Tape (CT) and Digi-Reel formats, suitable for both manual and automated assembly. MZ2029-601T and MZ2029-601Y are supplied in Tape & Reel (TR) format, optimized for high-volume automated production.
