ACML-0805-260-T Ferrite Bead Equivalent & Substitute Parts

Part Overview

The ACML-0805-260-T is a ferrite bead manufactured by Abracon LLC, rated at 26 Ohms @ 100 MHz in a 0805 (2012 Metric) surface mount package. This component is designed for electromagnetic interference (EMI) suppression in single-line applications with a maximum current rating of 1.5A and DC resistance of 50mOhm. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across multiple suppliers while maintaining equivalent electrical and mechanical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ACML-0805-260-T is determined by the following critical parameters:

• Package / Case: All substitutes must be 0805 (2012 Metric) surface mount to ensure mechanical and electrical compatibility with existing PCB layouts
• Operating Temperature Range: All substitutes must support -55°C ~ 125°C minimum
• Impedance @ Frequency: Substitutes rated at 26 Ohms @ 100 MHz provide direct electrical equivalence; substitutes rated at 30-31 Ohms @ 100 MHz represent parametric alternatives within acceptable impedance tolerance bands for EMI suppression applications
• Current Rating (Max): Substitutes rated at 1.5A or higher maintain or exceed the current handling capability
• DC Resistance (DCR): Substitutes with 50mOhm or lower DCR maintain or improve power dissipation characteristics
• RoHS Status: All substitutes maintain ROHS3 compliance for regulatory consistency
• Moisture Sensitivity Level (MSL): All substitutes maintain MSL 1 (Unlimited) for storage and handling compatibility

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent (Impedance Match): No substitute parts are rated at exactly 26 Ohms @ 100 MHz. The ACML-0805-310-T from Abracon LLC provides the closest impedance match at 31 Ohms @ 100 MHz while maintaining identical current rating (1.5A) and DCR (50mOhm) specifications. This part remains in Active product status.

Parametric Equivalents (30 Ohms @ 100 MHz): The following parts are rated at 30 Ohms @ 100 MHz and represent parametric alternatives:

• MMZ2012R300AT000 and MMZ2012Y300BT000 (TDK Corporation) maintain the 1.5A current rating and 50mOhm DCR but carry Last Time Buy status, indicating discontinued product lines
• 2508053007Y3 (Fair-Rite Products Corp.), 74279206 (Würth Elektronik), and MH2029-300Y (Bourns Inc.) offer enhanced specifications with 3.0A current rating and reduced DCR (30mOhm or 25mOhm), providing superior performance margins while maintaining Active product status

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C ~ 125°C operating temperature range. Selection should prioritize Active status parts for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ACML-0805-310-T replace ACML-0805-260-T directly? A: Yes. Both parts share identical current rating (1.5A), DCR (50mOhm), package (0805 2012 Metric), and operating temperature range (-55°C ~ 125°C). The impedance difference of 5 Ohms (26 vs. 31 Ohms @ 100 MHz) represents a 19% variance and must be evaluated against circuit EMI suppression requirements.

Q: What is the difference between the TDK MMZ2012R300AT000 and MMZ2012Y300BT000? A: Both parts are electrically identical with 30 Ohms @ 100 MHz impedance, 1.5A current rating, and 50mOhm DCR. The primary difference is internal construction (R vs. Y series designation). Both carry Last Time Buy status.

Q: Why do some substitutes have higher current ratings (3.0A vs. 1.5A)? A: Parts such as 2508053007Y3, 74279206, and MH2029-300Y are designed for higher current applications. These parts provide additional performance margin and can be used in place of the 1.5A-rated ACML-0805-260-T without derating concerns.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory consistency with the original ACML-0805-260-T.

Q: Does package size vary among substitutes? A: No. All substitute parts use the 0805 (2012 Metric) surface mount package with compatible footprints. Height variations (1.05mm to 1.10mm maximum) and minor dimensional differences (width 1.20mm to 1.25mm) remain within standard PCB assembly tolerances.

Q: Which substitute offers the best long-term availability? A: Parts with Active product status (ACML-0805-310-T, 2508053007Y3, 74279206, MH2029-300Y) provide superior long-term supply chain stability compared to Last Time Buy parts (MMZ2012R300AT000, MMZ2012Y300BT000).
