EXC-ML45A910H Equivalent & Substitute Parts

Part Overview

The EXC-ML45A910H is a single-line ferrite bead manufactured by Panasonic Electronic Components, designed for signal line filtering applications. This component delivers 91 Ohms of impedance at 100 MHz with a maximum current rating of 3A and operates in a compact 1806 (4516 Metric) surface mount package. The product is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the EXC-ML45A910H is determined by the following critical parameters: impedance value at 100 MHz, current rating capability, DC resistance, package form factor, and filter type classification. Parts are grouped into two categories based on these criteria:

Direct Equivalent (Identical Impedance & Package): HI1806N910R-10 matches the primary electrical specification (91 Ohms @ 100 MHz) and maintains the same 1806 package footprint, enabling direct board-level substitution.

Functional Equivalent (Similar Impedance, Different Package): 742792113 provides comparable impedance performance (120 Ohms @ 100 MHz) within acceptable tolerance for signal line applications but uses a smaller 1206 package. This substitution requires PCB layout verification.

Similar Performance (Different Impedance & Package): MPZ2012S101AT000 operates at 100 Ohms @ 100 MHz in a 0805 package with higher current capability (4A). This part addresses applications where package size reduction is prioritized and impedance tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

HI1806N910R-10 is the primary substitute for direct replacement applications. This part maintains identical impedance (91 Ohms @ 100 MHz) and package geometry (1806), ensuring compatibility with existing PCB layouts. The component is active in production, ROHS3 compliant, and rated for -40°C to 125°C operation. The increased DC resistance (30 mOhm versus 16 mOhm) is acceptable for signal line filtering where power dissipation is minimal.

742792113 serves as a functional alternative when package size reduction is acceptable. Operating at 120 Ohms @ 100 MHz, this part provides slightly higher impedance suitable for signal line applications with broader tolerance margins. The 1206 package reduces board footprint by approximately 29% compared to the 1806 form factor. ROHS3 compliance and -55°C to 125°C temperature range support extended environmental specifications.

MPZ2012S101AT000 is suitable for space-constrained designs where impedance tolerance of ±10% is acceptable. The 0805 package offers maximum size reduction (56% smaller than 1806) and provides higher current capability (4A). However, this part is classified as a power line filter, requiring verification that power line filtering characteristics do not conflict with signal line application requirements.

Frequently Asked Questions (FAQ)

Q: Can HI1806N910R-10 replace EXC-ML45A910H without PCB modification? A: Yes. HI1806N910R-10 maintains identical impedance (91 Ohms @ 100 MHz) and 1806 package footprint, enabling direct substitution without PCB layout changes.

Q: What is the impedance tolerance difference between the main part and substitutes? A: The main part specifies 91 Ohms @ 100 MHz. HI1806N910R-10 matches this specification exactly. 742792113 operates at 120 Ohms (approximately +32% higher), and MPZ2012S101AT000 operates at 100 Ohms (approximately +10% higher). Impedance tolerance acceptance depends on circuit design margins.

Q: Why does HI1806N910R-10 have higher DC resistance (30 mOhm vs. 16 mOhm)? A: DC resistance variation is common across ferrite bead manufacturers and product lines. For signal line applications with 3A maximum current, the additional 14 mOhm resistance results in negligible power dissipation (approximately 0.126W at maximum current) and does not impact filtering performance.

Q: Is 742792113 suitable for high-frequency signal integrity applications? A: Yes. 742792113 is rated for signal line filtering with 120 Ohms impedance at 100 MHz. The higher impedance may provide improved attenuation for certain frequency ranges but requires circuit simulation to confirm compatibility with original design specifications.

Q: Can MPZ2012S101AT000 be used in place of the original part? A: MPZ2012S101AT000 is classified as a power line filter rather than a signal line filter. While impedance (100 Ohms @ 100 MHz) is comparable, the different filter classification and significantly smaller 0805 package require design verification before substitution.

Q: What are the compliance differences between substitute parts? A: All active substitutes (HI1806N910R-10, 742792113, MPZ2012S101AT000) are ROHS3 compliant and REACH unaffected. Operating temperature ranges vary: HI1806N910R-10 operates -40°C to 125°C, while 742792113 and MPZ2012S101AT000 extend to -55°C to 125°C, providing broader environmental support.

Q: Does package size reduction affect electrical performance? A: Package size does not directly affect impedance or filtering characteristics. However, smaller packages (1206 and 0805) may exhibit different parasitic inductance and capacitance, potentially affecting high-frequency response. Circuit-level testing is recommended for critical applications.
