Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34682C is determined by the following critical parameters:

• Inductance value must be 6.8 µH within ±30% tolerance
• Shielding requirement must be maintained (shielded construction)
• Operating temperature range must encompass -40°C to 125°C
• Surface mount package configuration required
• RoHS3 compliance mandatory
• Moisture sensitivity level 1 acceptable

The substitute part SRR4018-6R8Y meets these core substitution criteria. While the substitute exhibits improved electrical characteristics (lower DCR, higher current rating), these enhancements do not disqualify it from substitution. The substitute maintains identical inductance specification, shielding type, temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 34682C and SRR4018-6R8Y maintain Active product status with full RoHS3 compliance and REACH unaffected classification. The substitute part SRR4018-6R8Y provides equivalent inductance and temperature performance with enhanced electrical characteristics. The lower DC resistance (100 mOhm vs. 150 mOhm) and higher current rating (1.5 A vs. 1 A) of the substitute represent operational improvements without compromising the original design intent. Physical package dimensions differ between the two parts, requiring PCB layout verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can SRR4018-6R8Y directly replace 34682C in all applications?

A: Electrical substitution is valid based on matching inductance, tolerance, shielding, and temperature specifications. Physical package dimensions differ (0.205" × 0.205" vs. 0.189" × 0.189"), requiring PCB footprint compatibility assessment.

Q: What are the key differences between these inductors?

A: The substitute offers lower DC resistance (100 mOhm vs. 150 mOhm) and higher current saturation capability (1.5 A vs. 1 A). Both maintain identical inductance values, shielding, temperature range, and compliance certifications.

Q: Are both parts suitable for high-temperature applications?

A: Both parts operate across -40°C to 125°C, meeting industrial temperature requirements identically.

Q: What packaging formats are available?

A: The 34682C is supplied in Tape & Reel format. The SRR4018-6R8Y is available in Cut Tape and Digi-Reel packaging options.

Q: Do both parts meet RoHS requirements?
