Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0770.683NLT is determined by the following criteria:

• Inductance value must equal 68 µH
• Current rating must meet or exceed 400 mA
• DC resistance must not exceed 860mOhm
• Shielding configuration must be unshielded
• Mounting type must be surface mount
• Operating temperature range must encompass or match -40°C ~ 130°C
• RoHS3 compliance is required

The SDR0603-680KL from Bourns Inc. satisfies all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the P0770.683NLT and SDR0603-680KL are Active products with ROHS3 compliance and REACH unaffected status. The SDR0603-680KL provides improved electrical performance with lower DC resistance (720mOhm vs. 860mOhm), tighter inductance tolerance (±10% vs. ±20%), and higher current saturation rating (540mA vs. 400mA). The operating temperature range of the SDR0603-680KL extends to 125°C, which is 5°C lower than the P0770.683NLT maximum. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification and are suitable for identical surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the SDR0603-680KL replace the P0770.683NLT in all applications?

A: Yes, provided the application does not require operation above 125°C. The SDR0603-680KL meets or exceeds all critical electrical parameters including current rating, DC resistance, and inductance value.

Q: What is the significance of the lower DC resistance in the SDR0603-680KL?

A: Lower DC resistance (720mOhm vs. 860mOhm) reduces power dissipation and heat generation during operation, improving overall circuit efficiency.

Q: Are there physical size differences between these components?

A: Yes. The P0770.683NLT measures 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm), while the SDR0603-680KL measures 0.228" L x 0.228" W x 0.154" H (5.80mm x 5.80mm x 3.90mm). PCB layout and clearance requirements must be verified before substitution.

Q: Do both components require the same handling and storage conditions?

A: Yes. Both components are classified as MSL 1 (Unlimited), requiring no special moisture control during storage or handling.

Q: What is the difference in inductance tolerance between these parts?

A: The P0770.683NLT has ±20% tolerance, while the SDR0603-680KL has ±10% tolerance. The tighter tolerance of the SDR0603-680KL may provide improved circuit performance in applications sensitive to inductance variation.
