Engineering Selection Recommendations

BLM03BX182SN1D is a direct parametric equivalent with identical impedance (1.8 kOhms @ 100 MHz) and package specifications. This substitute offers enhanced current handling capacity (140mA versus 100mA) and reduced DC resistance (2.5Ohm versus 3.8Ohm). Both parts maintain Active product status, ROHS3 compliance, and REACH unaffected designation. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel), which does not affect electrical performance or board-level compatibility.

BLM03HD152FN1D shares the same base product number (BLM03HD) and package specifications but operates at a lower impedance (1.5 kOhms @ 100 MHz). This part is not a direct substitute for applications requiring 1.8 kOhms impedance specification. Selection of this part requires circuit-level impedance compatibility verification.

Frequently Asked Questions (FAQ)

Q: Can BLM03BX182SN1D replace BLM03HD182FN1D in production?

A: Yes. Both parts deliver identical impedance (1.8 kOhms @ 100 MHz) and operate within the same 0201 package envelope. The BLM03BX182SN1D provides superior electrical performance with higher current rating and lower DC resistance. Packaging format differs (Tape & Reel versus Cut Tape & Digi-Reel) but does not affect circuit functionality or PCB assembly compatibility.

Q: Is BLM03HD152FN1D compatible with BLM03HD182FN1D applications?

A: No. The BLM03HD152FN1D operates at 1.5 kOhms impedance, which differs from the 1.8 kOhms specification of the BLM03HD182FN1D. Impedance is a primary electrical parameter that determines filtering characteristics. Substitution requires circuit-level analysis to confirm impedance tolerance acceptance.

Q: What are the key parameters that determine substitution eligibility?

A: Impedance @ 100 MHz, package type (0201), filter type (Signal Line), number of lines (1), and operating temperature range (-55°C ~ 125°C) must remain constant. Current rating and DC resistance may improve in substitute parts. Compliance certifications (RoHS3, REACH) must match.

Q: Does packaging format (Cut Tape versus Tape & Reel) affect electrical performance?

A: No. Packaging format is a supply and handling specification only. Both Cut Tape (CT) & Digi-Reel and Tape & Reel (TR) formats contain identical components with identical electrical characteristics. Format selection depends on assembly process requirements and inventory management.

Q: Are all substitute parts manufactured by Murata Electronics?

A: Yes. All parts listed are Murata Electronics ferrite beads within the BLM series, ensuring consistent manufacturing standards and quality control.
