Substitute Part Grouping Explanation

Substitute parts for the Würth Elektronik 782963820 are qualified based on the following critical parameters:

• Package compatibility: 1806 (4516 Metric) surface mount form factor
• Single signal line configuration
• Current handling capability: 4.6A maximum
• Operating temperature range: -55°C ~ 125°C
• AEC-Q200 automotive qualification
• Impedance range at 100 MHz: 75–82 Ohms
• DC resistance: 15–20mOhm maximum

The Murata Electronics BLM41PG750SH1L meets these substitution criteria with a 75 Ohm impedance specification, which falls within acceptable tolerance for signal line ferrite bead applications in this package class.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 782963820 and Murata Electronics BLM41PG750SH1L are active products with AEC-Q200 qualification, ROHS3 compliance, and identical MSL ratings. The primary difference is impedance specification: 82 Ohms versus 75 Ohms at 100 MHz. The Murata part offers lower DC resistance (15mOhm versus 20mOhm), which reduces insertion loss in signal line applications. Both parts share identical current ratings, package dimensions, and operating temperature ranges, confirming mechanical and thermal compatibility. Selection between these parts depends on the specific impedance requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the Murata BLM41PG750SH1L directly replace the Würth Elektronik 782963820?

A: Yes, for applications where 75 Ohm impedance is acceptable. Both parts are housed in the 1806 (4516 Metric) package with identical footprints and mounting requirements. Verify that your circuit design tolerates the 7 Ohm impedance difference at 100 MHz.

Q: Are there differences in current handling between these parts?

A: No. Both parts are rated for 4.6A maximum current. The Murata part features lower DC resistance (15mOhm versus 20mOhm), which results in reduced power dissipation at rated current.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the Würth Elektronik 782963820 and Murata Electronics BLM41PG750SH1L carry AEC-Q200 qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to 125°C.

Q: Are there packaging or moisture sensitivity concerns?

A: No. Both parts are supplied in Tape & Reel (TR) packaging with MSL rating 1 (Unlimited), indicating no moisture sensitivity limitations during storage or handling.

Q: What is the impedance tolerance between these substitute parts?

A: The Würth part specifies 82 Ohms at 100 MHz, while the Murata part specifies 75 Ohms at 100 MHz. This 7 Ohm difference represents approximately 8.5% variation. Confirm that your application circuit design accommodates this impedance range.
