SC62LCB-330 Equivalent & Substitute Parts

Part Overview

The SC62LCB-330 is a 33 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring 800 mA current handling capability. This component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and current rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC62LCB-330 is determined by the following critical parameters:

• Inductance Value: 33 µH with ±20% tolerance
• Current Rating: Minimum 800 mA continuous current handling
• Saturation Current (Isat): Minimum 630 mA
• DC Resistance (DCR): Maximum 460 mOhm
• Shielding: Shielded construction required
• Mounting Type: Surface mount configuration
• Operating Temperature: -40°C minimum to 125°C maximum
• Compliance: RoHS3 compliant, MSL 1

The substitute part VLCF5020T-330MR48 meets the inductance and shielding requirements but operates within a reduced current rating envelope (480 mA vs. 800 mA) and elevated operating temperature ceiling (105°C vs. 125°C). This part is suitable only for applications where the actual circuit current demand does not exceed 480 mA and thermal environment remains below 105°C.

Parameter Comparison

Engineering Selection Recommendations

Selection between SC62LCB-330 and VLCF5020T-330MR48 must be based on circuit current requirements and thermal operating conditions:

SC62LCB-330 is the primary selection for applications requiring:

• Continuous current operation at 800 mA or higher
• Operating environments up to 125°C
• Maximum DC resistance specification of 460 mOhm

VLCF5020T-330MR48 is acceptable only when:

• Circuit current demand does not exceed 480 mA continuous operation
• Operating temperature environment remains below 105°C
• The 62 mOhm increase in DC resistance (460 mOhm to 522 mOhm) is acceptable for the application
• Smaller physical footprint (5.00mm x 5.00mm vs. 6.30mm x 6.20mm) provides design advantage

Both parts maintain Active product status, RoHS3 compliance, and MSL 1 rating. Packaging format differs: SC62LCB-330 uses standard packaging while VLCF5020T-330MR48 is supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can VLCF5020T-330MR48 be used as a direct replacement for SC62LCB-330 in all applications?

A: No. The substitute part has reduced current rating (480 mA vs. 800 mA) and lower maximum operating temperature (105°C vs. 125°C). Substitution is valid only when circuit design operates within these lower limits.

Q: What is the impact of the 62 mOhm increase in DC resistance?

A: The VLCF5020T-330MR48 has maximum DCR of 522 mOhm compared to 460 mOhm for SC62LCB-330. This 14.6% increase results in higher power dissipation and heat generation. Verify thermal budget and current levels before substitution.

Q: Are the physical dimensions compatible on the PCB?

A: Both parts have identical seated height (2.00mm). However, VLCF5020T-330MR48 has smaller footprint (5.00mm x 5.00mm vs. 6.30mm x 6.20mm). PCB layout designed for SC62LCB-330 can accommodate the smaller substitute, but reverse substitution requires layout modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SC62LCB-330 and VLCF5020T-330MR48 are RoHS3 compliant, REACH unaffected, and carry MSL 1 rating with unlimited moisture sensitivity protection.

Q: What is the saturation current difference and why does it matter?

A: SC62LCB-330 has Isat of 630 mA while VLCF5020T-330MR48 has Isat of 480 mA. Saturation current defines the point where inductance begins to degrade. Operating above saturation current causes inductance loss and potential circuit malfunction. Ensure circuit peak current remains below the selected part's Isat rating.
