2474-33L Fixed Inductor - Equivalent & Substitute Parts

Part Overview

The 2474-33L is a 470 µH unshielded molded inductor manufactured by API Delevan Inc., designed for through-hole mounting in axial package configuration. This ferrite-core inductor features a 590 mA current rating and 1.03Ohm maximum DC resistance, operating across the temperature range of -55°C to 125°C. The part is currently in active production status. Finding equivalent and substitute parts becomes necessary when the primary variant requires RoHS3 compliance, alternative inventory availability, or engineering preference for validated alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 2474-33L is based strictly on electrical and mechanical parameter compatibility. The primary substitute identified is the 2474R-33L, which shares identical electrical specifications: 470 µH inductance at ±15% tolerance, 590 mA current rating, 1.03Ohm maximum DC resistance, and 290mA saturation current. Both parts utilize ferrite-core construction, unshielded configuration, and axial through-hole mounting with matching physical dimensions (0.240" Dia x 0.740" L / 6.10mm x 18.80mm).

The substitution is valid because the 2474R-33L maintains all critical electrical parameters within the same tolerances and operational envelope. The key compatibility parameters are:

• Inductance value and tolerance: 470 µH ±15%
• Current rating: 590 mA
• DC resistance: 1.03Ohm Max
• Saturation current: 290mA
• Core material and shielding: Ferrite, Unshielded
• Package and mounting: Axial Through Hole
• Physical dimensions: 0.240" Dia x 0.740" L

Engineering Selection Recommendations

2474R-33L as Primary Substitute: The 2474R-33L is the fully qualified substitute for the 2474-33L. This variant carries RoHS3 compliance status, making it mandatory for applications subject to RoHS3 regulatory requirements. Both parts maintain active product status from API Delevan Inc. and are available from current inventory. The 2474R-33L series provides superior compliance positioning while maintaining 100% electrical and mechanical parameter compatibility.

2474-33L Retention: The original 2474-33L remains suitable for applications where RoHS compliance is not a requirement and where non-compliant components are permitted by design specifications. This variant offers equivalent electrical performance and thermal characteristics.

Selection Criteria: Choose the 2474R-33L when RoHS3 compliance is required or preferred in design specifications. Select the 2474-33L only when explicitly permitted by application requirements and when RoHS exemption documentation is available.

Frequently Asked Questions (FAQ)

Q: Can I substitute 2474R-33L for 2474-33L in my circuit? A: Yes. The 2474R-33L provides identical electrical specifications, current rating, DC resistance, saturation characteristics, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two parts? A: The primary difference is RoHS compliance status. The 2474R-33L meets RoHS3 requirements, while the 2474-33L does not. All electrical parameters, inductance values, current ratings, and physical packaging are identical.

Q: Are the physical dimensions identical? A: Yes. Both the 2474-33L and 2474R-33L share identical axial package dimensions of 0.240" Dia x 0.740" L (6.10mm x 18.80mm), ensuring interchangeable through-hole mounting on PCBs.

Q: Does the RoHS3 compliance affect performance? A: No. RoHS3 compliance reflects material composition standards and does not alter electrical performance, inductance value, current rating, or operating temperature range. Both parts perform identically in circuit operation.

Q: Which part should I design into new products? A: For new designs, use the 2474R-33L (RoHS3 compliant variant) unless specific project constraints require the non-compliant 2474-33L. The compliant variant ensures regulatory flexibility and future supply chain alignment.

Q: Are both parts currently available? A: Yes. The 2474-33L has 683 pieces in inventory, while the 2474R-33L has 1647 pieces in inventory from original stock.
