Key Parameters

Substitute Part Grouping Explanation

Substitution of the 41331C is determined by the following critical parameters:

• Inductance value: 330 µH (exact match required)
• Toroidal core type with unshielded configuration
• Surface mount package with nonstandard dimensions
• Current rating capability: minimum 830 mA
• DC resistance within acceptable operating limits
• 10 kHz inductance test frequency alignment
• RoHS compliance and environmental certifications

The Amgis, LLC SH50S-0.9-330 meets these substitution criteria with compatible electrical characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The SH50S-0.9-330 serves as a direct functional substitute for the obsolete 41331C. Both components share identical inductance values and toroidal unshielded configurations. The substitute part offers superior current rating capability (900 mA versus 830 mA) and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The substitute maintains RoHS compliance through ROHS3 certification and is currently in active production status, ensuring long-term availability. Physical dimensions differ slightly between the two parts; the SH50S-0.9-330 measures 0.701" L x 0.669" W x 0.451" H compared to the 41331C at 0.690" L x 0.660" W x 0.390" H. DC resistance of the substitute is higher at 740mOhm maximum, which must be evaluated against circuit requirements. The substitute is supplied in Tape & Reel packaging, providing production-ready format.

Frequently Asked Questions (FAQ)

Q: Can the SH50S-0.9-330 directly replace the 41331C in existing designs?

A: The SH50S-0.9-330 matches the critical electrical parameters: 330 µH inductance, toroidal unshielded type, and surface mount configuration. Physical dimensions differ slightly, requiring PCB layout verification. The higher DC resistance (740mOhm versus 462mOhm) must be evaluated for thermal and efficiency impacts in the specific application circuit.

Q: What is the significance of the higher current rating on the substitute part?

A: The SH50S-0.9-330 is rated for 900 mA compared to the 41331C at 830 mA. This provides additional design margin and does not create compatibility issues when substituting into circuits designed for the lower-rated original part.

Q: Are there packaging differences between these parts?

A: The 41331C uses nonstandard packaging, while the SH50S-0.9-330 is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact electrical performance or PCB mounting compatibility.

Q: How do the operating temperature ranges compare?

A: The 41331C operates from -40°C to 85°C, while the SH50S-0.9-330 extends to -40°C to 125°C. The substitute part provides wider temperature coverage, beneficial for applications requiring extended thermal performance.

Q: What compliance certifications apply to the substitute part?

A: The SH50S-0.9-330 is ROHS3 compliant and REACH unaffected, matching the regulatory requirements of the original 41331C. Both parts carry EAR99 ECCN classification and 8504.50.4000 HTSUS code.
