SCRH62-330 Equivalent & Substitute Parts

Part Overview

The SCRH62-330 is a 33 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 840 mA continuous current with a maximum DC resistance of 450 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, shielding characteristics, and operating temperature ranges align with application requirements, enabling design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH62-330 is determined by the following critical parameters:

• Inductance value: 33 µH (±20% tolerance band)
• Shielding requirement: Shielded construction
• Current handling: Minimum 840 mA continuous rating
• DC resistance: Maximum 450 mOhm
• Mounting: Surface mount configuration
• Operating temperature: Minimum -40°C to 125°C range
• Compliance: RoHS3 and REACH status alignment

The VLCF5020T-330MR48 qualifies as a substitute based on matching inductance specification, shielded construction, and compliance certifications. However, current rating and temperature range parameters differ and must be evaluated against specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance with unlimited moisture sensitivity ratings, supporting long-term supply chain viability and manufacturing process compatibility.

The SCRH62-330 is suitable for applications requiring the full 840 mA current rating and extended upper temperature operation to 125°C. The VLCF5020T-330MR48 offers a more compact footprint (5.00mm × 5.00mm versus 7.10mm × 6.50mm) and lower profile (2.00mm versus 3.00mm), making it applicable to space-constrained designs where current requirements do not exceed 480 mA and operating temperature remains within -40°C to 105°C.

DC resistance differential (450 mOhm versus 522 mOhm) and saturation current variation must be evaluated against circuit performance specifications and thermal management requirements.

Frequently Asked Questions (FAQ)

Q: Can VLCF5020T-330MR48 replace SCRH62-330 in all applications?

A: Substitution is valid only when application current requirements do not exceed 480 mA continuous and maximum operating temperature does not exceed 105°C. The SCRH62-330 supports higher current (840 mA) and extended temperature range (-40°C to 125°C).

Q: What is the impact of DC resistance difference between these parts?

A: The VLCF5020T-330MR48 exhibits 522 mOhm maximum DCR compared to 450 mOhm for SCRH62-330. This 72 mOhm increase results in proportionally higher resistive losses and heat generation at equivalent current levels.

Q: Are package dimensions interchangeable?

A: No. SCRH62-330 measures 7.10mm × 6.50mm × 3.00mm while VLCF5020T-330MR48 measures 5.00mm × 5.00mm × 2.00mm. PCB layout and component placement must accommodate the specific footprint of the selected part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, supporting equivalent manufacturing and storage requirements.

Q: What determines saturation current selection?

A: Saturation current (Isat) defines the threshold at which inductance begins to degrade. SCRH62-330 saturates at 590 mA while VLCF5020T-330MR48 saturates at 480 mA. Circuit design must maintain operating current below saturation to preserve inductance stability.
