Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24180C is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 18 µH (exact match required)
• Current rating: minimum 1.25 A (24180C rated at 1.26 A)
• DC resistance: 150mOhm maximum (no increase permitted)
• Shielding configuration: unshielded
• Surface mount package: nonstandard form factor
• Operating temperature range: minimum -40°C to 85°C coverage
• RoHS3 compliance: mandatory for equivalent substitution

The Bourns Inc. SDR0604-180YL meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 24180C and SDR0604-180YL maintain active product status and full RoHS3 compliance. The SDR0604-180YL provides an extended operating temperature range to 125°C compared to the 24180C maximum of 85°C, offering additional thermal margin in applications requiring higher temperature operation. Current ratings are equivalent within 0.01 A tolerance. DC resistance specifications are identical at 150mOhm maximum. Selection between these parts should be based on packaging availability, lead time requirements, and thermal operating conditions specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-180YL directly replace the 24180C in all applications?

A: Yes, within the specified electrical and mechanical parameters. Both components share identical inductance (18 µH), DC resistance (150mOhm max), and current ratings (1.25–1.26 A). The SDR0604-180YL offers extended temperature operation to 125°C versus 85°C for the 24180C.

Q: What are the physical dimension differences between these parts?

A: The 24180C measures 0.228" L × 0.205" W × 0.177" H (5.80mm × 5.20mm × 4.50mm). The SDR0604-180YL measures 0.228" L × 0.228" W × 0.189" H (5.80mm × 5.80mm × 4.80mm). Width and height differ slightly; verify PCB layout compatibility before substitution.

Q: Are there packaging differences between these inductors?

A: The 24180C is supplied in Tape & Reel (TR) packaging. The SDR0604-180YL is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are surface mount compatible with identical mounting type specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 24180C and SDR0604-180YL are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8504.50.4000. Moisture sensitivity level is 1 (unlimited) for both components.

Q: What is the difference in self-resonant frequency between these parts?

A: The 24180C has a self-resonant frequency of 20 MHz, while the SDR0604-180YL is rated at 18 MHz. This 2 MHz difference may be relevant in high-frequency filtering applications near these frequency ranges.
