SC3316F-331 Equivalent & Substitute Parts

Part Overview

The SC3316F-331 is a 330 µH unshielded wirewound surface mount inductor manufactured by Signal Transformer. Rated for 680 mA continuous current with a maximum DC resistance of 1.02Ohm, this component is designed for applications requiring fixed inductance in compact form factors. The part is currently active in production and ROHS3 compliant. Substitute parts may be required due to inventory availability, lead time constraints, or specific application requirements within the defined electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the SC3316F-331 is determined by strict equivalence across the following critical parameters:

• Inductance value: 330 µH (±20% tolerance maintained)
• DC Resistance: 1.02Ohm maximum
• Current Rating: minimum 680 mA continuous
• Current Saturation: minimum 600 mA
• Shielding configuration: Unshielded
• Component type: Wirewound
• Mounting: Surface Mount
• Inductance test frequency: 100 kHz
• Compliance: ROHS3 compliant

The P0752.334NLT from Pulse Electronics meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the SC3316F-331 and P0752.334NLT are active production components with ROHS3 compliance and REACH unaffected status. The P0752.334NLT substitute offers an extended operating temperature range (-40°C to 130°C versus -40°C to 125°C) and slightly reduced physical dimensions. The substitute part carries a lower continuous current rating of 600 mA compared to the original 680 mA; however, both parts share identical saturation current specifications of 600 mA, making the substitute suitable for applications where the saturation point is the limiting factor. Selection between these parts should be based on application current requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the P0752.334NLT replace the SC3316F-331 in all applications?

A: The P0752.334NLT is electrically equivalent for inductance, tolerance, DC resistance, and saturation current. The substitute has a lower continuous current rating (600 mA vs 680 mA). Applications operating below 600 mA continuous current are fully compatible. Applications requiring continuous current between 600 mA and 680 mA must evaluate thermal and performance requirements.

Q: Are there physical mounting differences?

A: Both parts are surface mount wirewound inductors in nonstandard packages. The P0752.334NLT is slightly smaller (0.510" x 0.370" vs 0.530" x 0.390") with marginally greater height (0.215" vs 0.205"). These dimensional differences are minimal and typically accommodate standard PCB layouts designed for either part.

Q: Do compliance certifications differ?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.

Q: What is the operating temperature consideration?

A: The P0752.334NLT operates across -40°C to 130°C, providing a 5°C wider upper temperature range than the SC3316F-331 (-40°C to 125°C). This extended range may provide additional design margin in thermally demanding applications.

Q: Are inductance test frequencies the same?

A: Yes, both parts are tested at 100 kHz inductance frequency, ensuring measurement consistency and direct parameter comparison.
