- Package / Case: 0805 (2012 Metric)
- Mounting Type: Surface Mount
- Number of Lines: 1
- RoHS Status: ROHS3 Compliant
- Product Status: Active
Secondary Compatibility Parameters:
- Current Rating (Max): 2A or higher
- DC Resistance (DCR) (Max): 80mOhm or lower

Frequently Asked Questions (FAQ)
Q: Can 2176487-1 or 742792031 be used as direct replacements for MLP0805-301?
A: Yes. Both parts provide 300 Ohms impedance at 100 MHz in the 0805 package with active product status and ROHS3 compliance. The enhanced current rating (3A versus 2A) and reduced DC resistance (50mOhm versus 80mOhm) represent improved electrical performance. The extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 125°C) provides broader environmental coverage.
Q: What is the difference between power line and signal line filter types?
A: Filter type designation is provided in the input data. MLP0805-301 is designated as a power line filter. Substitute parts 2176487-1 and 742792031 are designated as signal line filters. The functional impedance and frequency characteristics remain equivalent at 300 Ohms @ 100 MHz. Application-specific requirements determine whether filter type designation is a critical selection criterion.
Q: Are 330 Ohm ferrite beads suitable substitutes for the 300 Ohm MLP0805-301?
A: Parts with 330 Ohms impedance (742792037, BBPY00201209331Y00, BBUP00201209331Y00, CTCB0805F-331P) represent near-equivalent alternatives. The 30 Ohm impedance difference (10% variance) may be acceptable depending on application-specific filtering requirements and impedance tolerance specifications. Circuit design validation is necessary to confirm suitability in the target application.
Q: What is the significance of the 320 Ohm part (74279220321)?
A: The 74279220321 provides 320 Ohms impedance at 100 MHz, representing a 20 Ohm difference (6.7% variance) from the MLP0805-301 specification. This part offers enhanced current rating (2.5A) and reduced DC resistance (50mOhm). The 320 Ohm impedance value falls between the 300 Ohm and 330 Ohm options and may serve as a compromise selection where intermediate impedance is acceptable.
Q: How do operating temperature ranges affect substitution decisions?
A: MLP0805-301 operates from -40°C to 125°C. Most substitute parts extend the lower temperature limit to -55°C, providing broader environmental coverage. CTCB0805F-301P, CTCB0805F-301S, and CTCB0805F-331P maintain the -40°C lower limit matching the original part. Selection depends on the target application's thermal requirements.
Q: What packaging formats are available for these ferrite beads?
A: All substitute parts are available in 0805 (2012 Metric) surface mount packages, matching the MLP0805-301 format. Packaging options include Tape & Reel (TR) and Cut Tape (CT) formats. Specific packaging requirements should be confirmed with procurement specifications.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of MLP0805-301. This ensures regulatory alignment for applications requiring ROHS3 certification.
Q: What is the inventory status of substitute parts?
A: Inventory levels vary across manufacturers and part numbers. TE Connectivity 2176487-1 has 47,973 pieces in stock. Würth Elektronik 742792031 has 51,961 pieces in stock. Pulse Electronics BBPY00201209301Y00 has 69,203 pieces in stock. Central Technologies CTCB0805F-301P has 8,658 pieces in stock. Specific inventory requirements should be confirmed with component suppliers.
