Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the B82422T1122J000 are qualified based on the following critical parameters:

• Inductance value of 1.2 µH within specified tolerance
• Current rating of 390 mA minimum
• DC resistance not exceeding 750mOhm (allowing for minor variation from the 700mOhm specification)
• Ferrite drum core construction
• 1210 (3225 Metric) package footprint
• Surface mount configuration
• Operating temperature range of -55°C to 125°C
• ROHS3 compliance

The CMH322522-1R2KL from Bourns Inc. meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the B82422T1122J000 and CMH322522-1R2KL are active production components with ROHS3 compliance and MSL Level 1 rating. The B82422T1122J000 carries AEC-Q200 qualification, indicating automotive-grade reliability. The CMH322522-1R2KL provides shielded construction, which may offer advantages in applications requiring reduced electromagnetic interference, while maintaining the same inductance value and current rating. The height difference of 0.011" (0.30mm) between seated positions should be evaluated for PCB layout constraints. Both parts are suitable for -55°C to 125°C operating environments and meet industrial compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CMH322522-1R2KL replace the B82422T1122J000 in all applications?

A: The CMH322522-1R2KL is electrically compatible with the same inductance value and current rating. The primary differences are the shielded versus unshielded core construction and a 0.011" increase in seated height. Applications requiring unshielded operation or with strict height constraints should retain the original B82422T1122J000.

Q: What is the significance of the inductance tolerance difference (±5% vs ±10%)?

A: The B82422T1122J000 offers tighter inductance tolerance at ±5%, while the CMH322522-1R2KL specifies ±10%. Applications requiring precise inductance values should account for this tolerance variation in circuit design.

Q: Are both parts suitable for automotive applications?

A: The B82422T1122J000 carries AEC-Q200 qualification for automotive use. The CMH322522-1R2KL does not list AEC-Q200 certification in the provided specifications. Automotive applications should verify compliance requirements with the manufacturer.

Q: What is the difference between shielded and unshielded construction?

A: The B82422T1122J000 is unshielded, while the CMH322522-1R2KL is shielded. Shielded inductors reduce electromagnetic field radiation and susceptibility to external interference. Selection depends on circuit layout and EMI requirements.

Q: Do both parts have the same PCB footprint?

A: Both parts use the 1210 (3225 Metric) package with identical length and width dimensions (0.126" x 0.098"). The seated height differs by 0.011" (0.30mm), which may affect clearance in space-constrained designs.
