Substitute Part Grouping Explanation

Substitution eligibility for the 2474-29L is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically to establish a valid substitute relationship:

• Inductance value: 220 µH
• Inductance tolerance: ±15%
• Current rating: 840 mA
• Saturation current: 430 mA
• DC resistance: 505 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
• Test frequency: 1 kHz

The 2474R-29L meets all substitution criteria as a direct equivalent part from the same manufacturer, with identical electrical performance and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 2474R-29L serves as a direct electrical and mechanical equivalent to the 2474-29L. Both parts are manufactured by API Delevan Inc. and maintain identical performance specifications across all critical parameters including inductance, current rating, DC resistance, and physical dimensions.

The primary distinction between these parts is regulatory compliance status. The 2474-29L is RoHS non-compliant, while the 2474R-29L is ROHS3 compliant. Selection between these parts should be based on the regulatory requirements of the target application and end-use market. Both parts maintain active production status and are available in adequate inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can the 2474R-29L be used as a direct replacement for the 2474-29L in existing designs?

A: Yes. The 2474R-29L is electrically and mechanically identical to the 2474-29L. All critical parameters including inductance value, current rating, DC resistance, core material, shielding configuration, mounting type, package type, and physical dimensions are equivalent. Direct substitution is valid from a performance standpoint.

Q: What is the difference between the 2474-29L and 2474R-29L?

A: The primary difference is RoHS compliance status. The 2474-29L is RoHS non-compliant, while the 2474R-29L is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any physical dimension differences between these parts?

A: No. Both the 2474-29L and 2474R-29L share identical physical dimensions of 0.240" diameter by 0.740" length (6.10mm x 18.80mm). Both are axial through-hole components suitable for identical PCB layouts.

Q: Do these parts have the same current handling capability?

A: Yes. Both parts are rated for 840 mA continuous current with a saturation current of 430 mA. DC resistance is specified at 505 mOhm maximum for both parts.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 2474R-29L is the appropriate choice. For applications without RoHS compliance requirements, either part is suitable based on availability and supply chain considerations.

Q: Are both parts available in adequate quantities?

A: Yes. The 2474-29L has 1084 pieces in current inventory, while the 2474R-29L has 1258 pieces available. Both parts maintain active production status.
