SC62CB-1R5 Equivalent & Substitute Parts

Part Overview

The SC62CB-1R5 is a 1.5 µH shielded inductor manufactured by Signal Transformer, rated for 4 A continuous current with a maximum DC resistance of 18 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is classified as Active product status. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design requirements permit alternative manufacturers meeting equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC62CB-1R5 is determined by the following critical parameters:

• Inductance Value: Must be 1.5 µH with ±30% tolerance
• Current Rating: Minimum 4 A continuous current capability
• DC Resistance: Maximum 18 mOhm to maintain equivalent power dissipation characteristics
• Shielding: Must be shielded to prevent electromagnetic interference
• Operating Temperature: Must support the full -40°C to 125°C range
• Mounting Type: Surface mount configuration required
• Compliance: ROHS3 compliance mandatory

The substitute part SLF7055T-1R5N4R0-3PF from TDK Corporation meets the core electrical requirements of inductance, current rating, and shielding. However, variations exist in DC resistance, saturation current, physical dimensions, and product lifecycle status that must be evaluated for specific application requirements.

Engineering Selection Recommendations

SC62CB-1R5 (Primary Component)

The SC62CB-1R5 maintains Active product status with 850 units in current inventory. This component is suitable for new designs and ongoing production. The part meets all ROHS3 and REACH compliance requirements with unlimited moisture sensitivity rating.

SLF7055T-1R5N4R0-3PF (Substitute Component)

The SLF7055T-1R5N4R0-3PF is classified as Not For New Designs. While this part meets the core electrical specifications (1.5 µH inductance, 4 A current rating, shielded configuration, ROHS3 compliance), its lifecycle status restricts application to legacy system support, repair, or replacement scenarios only. The higher saturation current (6.2 A vs. 2.83 A) and increased DC resistance (22.6 mOhm vs. 18 mOhm maximum) represent measurable deviations. The reduced operating temperature upper limit (105°C vs. 125°C) and larger physical footprint (7.00 x 7.00 x 5.80 mm vs. 6.30 x 6.20 x 2.50 mm) require PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can SLF7055T-1R5N4R0-3PF be used as a direct replacement for SC62CB-1R5?

A: Electrical substitution is possible based on matching inductance (1.5 µH), current rating (4 A), and shielding. However, the substitute part carries Not For New Designs status and exhibits higher DC resistance (22.6 mOhm vs. 18 mOhm maximum), lower maximum operating temperature (105°C vs. 125°C), and significantly larger physical dimensions. PCB layout compatibility must be confirmed before implementation.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by inductance value (1.5 µH ±30%), continuous current rating (minimum 4 A), shielded configuration, DC resistance specification (maximum 18 mOhm), operating temperature range (-40°C to 125°C), surface mount packaging, and ROHS3 compliance status.

Q: Does the increased DC resistance of the substitute part affect circuit performance?

A: The SLF7055T-1R5N4R0-3PF exhibits 22.6 mOhm maximum DC resistance compared to 18 mOhm maximum for the SC62CB-1R5. This 4.6 mOhm increase results in higher power dissipation and thermal generation. Circuit thermal analysis is required to determine acceptability for specific applications.

Q: Are there physical footprint compatibility concerns?

A: Yes. The substitute part measures 7.00 x 7.00 x 5.80 mm compared to the primary component's 6.30 x 6.20 x 2.50 mm. The larger footprint and significantly greater height require PCB layout verification to confirm clearance with adjacent components and assembly compatibility.

Q: What is the significance of the product status difference?

A: SC62CB-1R5 is Active and suitable for new designs with ongoing manufacturer support. SLF7055T-1R5N4R0-3PF is Not For New Designs, indicating the manufacturer no longer recommends this part for new applications. Use of the substitute is limited to legacy system maintenance, repair, or replacement of existing installations.
