Key Parameters

Substitute Part Grouping Explanation

Substitution of the Z0805C750ASMST is determined by the following critical parameters:

Physical Compatibility:

• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount
• Height (Max): 0.041" (1.05mm)
• Size / Dimension: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Electrical Compatibility:

• Number of Lines: 1 (single signal line)
• Current Rating (Max): 1A
• Operating Temperature: -55°C ~ 125°C
• DC Resistance (DCR) (Max): 100mOhm

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must match all physical and regulatory parameters. Impedance values at 100 MHz may vary within the range of 60 to 80 Ohms while maintaining electrical functionality in signal line filtering applications. All identified substitutes are active products or available through last-time-buy inventory, providing viable alternatives to the obsolete Z0805C750ASMST.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The Abracon LLC ACML series ferrite beads (ACML-0805-600-T, ACML-0805-700-T, ACML-0805-800-T) are recommended as primary substitutes. All three variants are active products with full ROHS3 compliance and MSL 1 rating. The ACML-0805-700-T provides impedance closest to the original 75 Ohm specification at 70 Ohms @ 100 MHz. The ACML-0805-800-T matches the original DC resistance specification at 100mOhm maximum. All Abracon variants maintain identical physical dimensions, current ratings, and operating temperature ranges.

Secondary Substitutes (Last Time Buy Status):

The TDK Corporation MMZ series ferrite beads (MMZ2012R600AT000 and MMZ2012Y600BT000) are available through last-time-buy inventory. Both parts provide 60 Ohms @ 100 MHz impedance with 100mOhm maximum DC resistance, matching the original part's electrical performance characteristics. These components maintain full ROHS3 compliance and MSL 1 rating. Last-time-buy status indicates limited availability; procurement planning should account for inventory depletion.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing manufacturing and storage protocols. All parts are rated for the same operating temperature range (-55°C to 125°C) and current capacity (1A maximum).

Frequently Asked Questions (FAQ)

Q: Can ACML-0805-600-T be used as a direct replacement for Z0805C750ASMST?

A: The ACML-0805-600-T is physically and electrically compatible. It matches all package dimensions, current rating, operating temperature, and compliance requirements. The impedance is 60 Ohms @ 100 MHz compared to the original 75 Ohms @ 100 MHz. DC resistance is 50mOhm maximum, lower than the original 100mOhm maximum. Selection depends on circuit impedance matching requirements.

Q: What is the difference between ACML-0805-700-T and ACML-0805-800-T?

A: Both parts are physically identical and meet all package and compliance specifications. ACML-0805-700-T provides 70 Ohms @ 100 MHz impedance with 80mOhm maximum DC resistance. ACML-0805-800-T provides 80 Ohms @ 100 MHz impedance with 100mOhm maximum DC resistance, matching the original part's DC resistance specification. Selection depends on the required impedance value for the application.

Q: Are TDK MMZ2012R600AT000 and MMZ2012Y600BT000 interchangeable?

A: Both TDK parts are physically and electrically identical, providing 60 Ohms @ 100 MHz impedance with 100mOhm maximum DC resistance. Both maintain full ROHS3 compliance and MSL 1 rating. The parts are interchangeable from an engineering standpoint. Availability differences may exist due to last-time-buy status.

Q: Does packaging format affect substitution compatibility?

A: The Z0805C750ASMST is supplied in Cut Tape (CT) format. Substitute parts are available in both Cut Tape (CT) and Tape & Reel (TR) formats. Physical component specifications remain identical regardless of packaging format. Procurement and handling procedures may differ based on packaging selection.

Q: What is the significance of "Last Time Buy" status for TDK parts?

A: Last Time Buy status indicates that TDK has announced end-of-life for these components. Inventory is available but will not be replenished after current stock is depleted. For long-term production requirements, Abracon LLC active products are recommended to ensure sustained availability.

Q: Can impedance variation affect circuit performance?

A: Ferrite beads function as frequency-dependent impedance elements in signal line filtering applications. Impedance values ranging from 60 to 80 Ohms @ 100 MHz provide similar filtering characteristics for most common applications. Circuit-specific requirements should be evaluated to determine acceptable impedance tolerance.

Q: Are all substitute parts RoHS3 compliant?

A: All identified substitute parts (Abracon ACML series and TDK MMZ series) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original Z0805C750ASMST specifications.
