Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTCB0805F-751M is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: 0805 (2012 Metric) surface mount form factor
• Impedance @ Frequency: 750 Ohms @ 100 MHz (exact match required for primary substitutes)
• Current Rating (Max): 200mA minimum
• DC Resistance (DCR) (Max): 500mOhm maximum
• Operating Temperature: -40°C ~ 125°C compatibility
• RoHS3 Compliance

Secondary Substitution Criteria:

• Impedance @ Frequency: 600 Ohms @ 100 MHz (alternative impedance value for applications with relaxed impedance tolerance)
• Current Rating (Max): 300mA (higher current capability acceptable for derating scenarios)
• DC Resistance (DCR) (Max): 400mOhm (lower DCR acceptable for improved performance)

Substitute parts are grouped into two categories: exact impedance matches (750 Ohms @ 100 MHz) and alternative impedance matches (600 Ohms @ 100 MHz). All substitute parts maintain the 0805 package form factor and surface mount mounting type.

Engineering Selection Recommendations

Primary Substitute: MLS0805-4S4-751 (Ferroxcube)

The MLS0805-4S4-751 is the direct equivalent to the CTCB0805F-751M. This part maintains identical electrical specifications: 750 Ohms @ 100 MHz impedance, 200mA current rating, and 500mOhm DC resistance. The component is manufactured by Ferroxcube, an active supplier with 844 pieces in current inventory. The MLS0805-4S4-751 is ROHS3 compliant and operates across the same temperature range (-40°C ~ 125°C). This substitute provides seamless design compatibility without circuit modification.

Secondary Substitutes: MLN0805-601 and MLS0805-4S7-601 (Ferroxcube)

The MLN0805-601 and MLS0805-4S7-601 are alternative impedance substitutes with 600 Ohms @ 100 MHz. These parts are suitable for applications where impedance tolerance permits a 150 Ohm reduction from the original specification. Both parts are manufactured by Ferroxcube and are ROHS3 compliant.

The MLN0805-601 maintains the original 200mA current rating and 500mOhm DC resistance, providing a direct electrical substitute with alternative impedance.

The MLS0805-4S7-601 offers enhanced performance characteristics with 300mA current rating and 400mOhm DC resistance, enabling operation at higher current levels and reduced insertion loss. This part is suitable for applications requiring improved thermal performance or higher current capacity.

All substitute parts are available from active suppliers and maintain the 0805 (2012 Metric) surface mount package form factor.

Frequently Asked Questions (FAQ)

Q: Can the MLS0805-4S4-751 be used as a direct replacement for the CTCB0805F-751M?

A: Yes. The MLS0805-4S4-751 is a direct equivalent with identical impedance (750 Ohms @ 100 MHz), current rating (200mA), DC resistance (500mOhm), package form factor (0805), and operating temperature range (-40°C ~ 125°C). No circuit modification is required.

Q: What is the difference between the 750 Ohm and 600 Ohm ferrite bead substitutes?

A: The primary difference is impedance at 100 MHz. The MLS0805-4S4-751 provides 750 Ohms @ 100 MHz, matching the original specification. The MLN0805-601 and MLS0805-4S7-601 provide 600 Ohms @ 100 MHz. Selection depends on circuit impedance requirements and EMI suppression specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The CTCB0805F-751M and all listed substitute parts (MLS0805-4S4-751, MLN0805-601, MLS0805-4S7-601) are ROHS3 compliant.

Q: What is the difference between MLN0805-601 and MLS0805-4S7-601?

A: Both parts provide 600 Ohms @ 100 MHz impedance. The MLN0805-601 has a 200mA current rating and 500mOhm DC resistance. The MLS0805-4S7-601 has a higher 300mA current rating and lower 400mOhm DC resistance, providing enhanced performance for higher current applications.

Q: Can the 0805 package parts be used interchangeably on the same PCB?

A: Yes. All listed parts use the 0805 (2012 Metric) surface mount package form factor with identical footprint dimensions (0.079" L x 0.047" W minimum). Physical placement on PCB is interchangeable.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate across -40°C to 125°C, matching the original CTCB0805F-751M specification.

Q: Is the MLS0805-4S7-601 suitable for applications requiring higher current capacity?

A: Yes. The MLS0805-4S7-601 supports 300mA maximum current, compared to 200mA for the original part and other substitutes. This part is suitable for applications requiring higher current operation or thermal derating scenarios.
