HC50-8401SM Equivalent & Substitute Parts

Part Overview

The HC50-8401SM is an 8.4 µH shielded toroidal inductor manufactured by Gowanda Electronics, designed for surface mount applications requiring high current handling and low DC resistance. This component is classified as Active product status with 1110 units in current inventory. Substitute parts become necessary when addressing specific application requirements such as inductance value optimization, shielding configuration changes, packaging format preferences, or supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HC50-8401SM is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Inductance value: 8.4 µH (±20% tolerance band acceptable)
• Current rating: minimum 10.4 A
• DC resistance: 8.3 mOhm maximum
• Mounting type: Surface Mount
• Package footprint: 0.740" x 0.740" (18.80mm x 18.80mm)
• Operating temperature range: must encompass -30°C to 130°C minimum

Allowable Variations:

• Shielding configuration (shielded or unshielded)
• Packaging format (Tape & Reel or Tube)
• Height dimension (within nonstandard package tolerance)
• Self-resonant frequency (when not specified as critical)

The PE-53682NL from Pulse Electronics is identified as a substitute part. However, this part exhibits a significant inductance deviation (4.7 µH versus 8.4 µH), representing a 44% reduction from the main part specification. This inductance difference places the PE-53682NL outside the acceptable substitution range for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Based on provided specifications and compliance data:

The PE-53682NL does not qualify as a direct substitute for the HC50-8401SM due to inductance value mismatch. The 4.7 µH inductance of the PE-53682NL deviates significantly from the 8.4 µH specification of the HC50-8401SM, exceeding acceptable tolerance bands for direct replacement.

The PE-53682NL may be considered only in applications where circuit design permits inductance value modification or where a lower inductance value is functionally acceptable. Such applications require circuit re-analysis and validation.

For applications requiring strict adherence to 8.4 µH inductance specification with shielded configuration, the HC50-8401SM remains the appropriate selection. The part maintains Active product status with adequate inventory availability (1110 units).

The PE-53682NL offers ROHS3 compliance, which may be relevant for specific regulatory requirements, but this compliance advantage does not override the inductance incompatibility for direct substitution purposes.

Frequently Asked Questions (FAQ)

Q: Can PE-53682NL replace HC50-8401SM in my circuit?

A: Direct replacement is not supported. The PE-53682NL inductance value (4.7 µH) differs substantially from the HC50-8401SM specification (8.4 µH). Substitution requires circuit redesign and validation.

Q: What are the critical parameters for substitution?

A: Inductance value, current rating, DC resistance, mounting type, and package footprint are the primary determinants. The PE-53682NL fails the inductance criterion.

Q: Does the unshielded configuration of PE-53682NL affect compatibility?

A: Shielding configuration differences are allowable variations in substitution analysis. However, the inductance mismatch is the limiting factor for this part pair.

Q: Are there packaging format differences between these parts?

A: Yes. HC50-8401SM is supplied in Tape & Reel format, while PE-53682NL is supplied in Tube format. Both formats are standard for surface mount components and do not prevent substitution if other parameters align.

Q: What is the operating temperature range compatibility?

A: PE-53682NL operating range (-40°C to 130°C) encompasses the HC50-8401SM range (-30°C to 130°C), making temperature specifications compatible.

Q: How do the physical dimensions compare?

A: Both parts share identical footprint dimensions (0.740" x 0.740" or 18.80mm x 18.80mm). Height differs by 0.010" (0.25mm), which is negligible for surface mount applications.
