Key Parameters

Substitute Part Grouping Explanation

The B82462G4154M000 from EPCOS - TDK Electronics qualifies as a direct substitute based on the following critical parameters:

Inductance value matches at 150 µH with identical ±20% tolerance. Both parts maintain shielded construction for electromagnetic interference mitigation. Surface mount packaging and nonstandard case dimensions ensure mechanical compatibility. The substitute part exceeds the original current rating specification at 380 mA versus 350 mA, providing operational margin. DC resistance of 1.05Ohm Max is lower than the original 1.68Ohm Max, resulting in reduced power dissipation. Both components comply with ROHS3 and maintain MSL 1 rating. The substitute part carries active product status with AEC-Q200 automotive qualification and an extended operating temperature range of -55°C to 150°C.

Parameter Comparison

Engineering Selection Recommendations

The B82462G4154M000 is suitable for applications currently using the SCRH64B-151. The substitute part's active product status ensures long-term availability and supply chain continuity. Both components maintain identical inductance specifications and tolerance bands, supporting direct functional replacement in existing circuit designs. The substitute part's lower DC resistance reduces thermal dissipation in the inductor, which may improve overall circuit efficiency. Extended temperature range capability of the substitute part provides additional operational margin for demanding environments. Both parts carry equivalent compliance certifications (ROHS3, MSL 1), supporting regulatory requirements without modification.

Frequently Asked Questions (FAQ)

Q: Can the B82462G4154M000 directly replace the SCRH64B-151 in existing designs?

A: Yes. Both inductors share identical 150 µH inductance values with ±20% tolerance, shielded construction, surface mount packaging, and equivalent compliance ratings. The substitute part's higher current rating and lower DC resistance provide operational advantages.

Q: What are the key differences between these two inductors?

A: The primary differences are product status (obsolete versus active), DC resistance (1.68Ohm versus 1.05Ohm), current rating (350 mA versus 380 mA), and operating temperature range (-40°C to 125°C versus -55°C to 150°C). The substitute part includes AEC-Q200 automotive qualification.

Q: Are there any package or footprint compatibility concerns?

A: Both parts use nonstandard surface mount packages with similar physical dimensions. The original measures 0.256" L x 0.252" W x 0.205" H, while the substitute measures 0.248" L x 0.248" W x 0.118" H. Verify PCB layout compatibility before implementation.

Q: Does the lower DC resistance of the substitute part affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation in the inductor. This generally improves circuit efficiency and thermal performance without affecting inductance value or functional behavior in the circuit.

Q: Are both parts suitable for automotive applications?

A: The substitute part B82462G4154M000 carries AEC-Q200 qualification for automotive use. The original SCRH64B-151 does not list automotive certification in the provided specifications.
