Substitute Part Grouping Explanation

The API Delevan 2474R-25L qualifies as a direct substitute for the 2474-25L based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Inductance value: 100 µH with ±15% tolerance
• Current rating: 1.3 A minimum
• Saturation current: 640 mA minimum
• DC resistance: 208 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package type: Axial
• Physical dimensions: 0.240" Dia x 0.740" L (6.10mm x 18.80mm)
• Operating temperature range: -55°C to 125°C

The 2474R-25L maintains all specified electrical performance characteristics and physical form factor, making it functionally equivalent for circuit applications requiring these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 2474-25L and 2474R-25L are Active status products from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 2474R-25L achieves ROHS3 compliance, while the 2474-25L is RoHS non-compliant. Selection between these parts should be based on applicable regulatory requirements for your application. Both parts maintain REACH Unaffected status and EAR99 export classification. Inventory availability may also influence selection, with the 2474R-25L currently showing higher stock levels (4327 pcs vs. 1125 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 2474R-25L replace the 2474-25L in existing designs?

A: Yes. The 2474R-25L is electrically and mechanically identical to the 2474-25L. All critical parameters including inductance, current rating, DC resistance, core material, shielding, mounting type, package configuration, and operating temperature range are equivalent. Direct substitution is valid for circuit applications.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 2474R-25L is ROHS3 compliant, while the 2474-25L is RoHS non-compliant. All other specifications are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share the same axial package dimensions of 0.240" diameter by 0.740" length (6.10mm x 18.80mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do these inductors have the same temperature operating range?

A: Yes. Both the 2474-25L and 2474R-25L operate across -55°C to 125°C, providing equivalent thermal performance for industrial applications.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 2474R-25L. For applications without RoHS compliance mandates, either part is functionally suitable. Verify your specific design and regulatory requirements before final selection.
