Engineering Selection Recommendations

Primary Selection - 4922-15L: The 4922-15L is suitable for applications where RoHS non-compliant components are acceptable or where legacy design requirements specify this exact part number. Current inventory of 663 pieces supports immediate availability for production requirements.

Alternative Selection - 4922R-15L: The 4922R-15L provides identical electrical and mechanical performance with the addition of ROHS3 compliance. This variant is recommended for new designs, applications subject to environmental regulations, or supply chain strategies requiring RoHS-compliant components. Inventory of 3490 pieces provides enhanced supply security.

Both parts are classified as active products from API Delevan Inc. and are suitable for direct substitution based on electrical specifications, physical dimensions, and thermal operating range. Selection between these parts depends on compliance requirements and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-15L replace the 4922-15L in existing designs?

A: Yes. The 4922R-15L is electrically and mechanically equivalent to the 4922-15L. All critical parameters including inductance value, current rating, DC resistance, core material, dimensions, and operating temperature range are identical. The primary difference is RoHS3 compliance status.

Q: What is the difference between the 4922-15L and 4922R-15L?

A: The 4922R-15L is RoHS3 compliant, while the 4922-15L is RoHS non-compliant. All other specifications—inductance, current rating, DC resistance, physical dimensions, and thermal range—are identical between the two parts.

Q: Are these parts pin-compatible?

A: Both parts use surface mount technology with identical physical dimensions (0.505" L × 0.240" W × 0.230" H maximum). They are footprint-compatible and can be used interchangeably on the same PCB layout.

Q: What does the ±15% inductance tolerance mean?

A: The inductance value of 15 µH can vary between 12.75 µH and 17.25 µH across the production range. This tolerance is measured at 1 kHz test frequency and applies to both the 4922-15L and 4922R-15L.

Q: Can these inductors handle 2.11 A continuously?

A: Yes. Both the 4922-15L and 4922R-15L are rated for 2.11 A continuous current. The saturation current (Isat) is also 2.11 A, indicating the current level at which inductance begins to degrade significantly.

Q: What is the DC resistance specification?

A: The maximum DC resistance (DCR) is 89 mOhm for both parts. This specification represents the resistive losses in the wire windings and affects power dissipation in the inductor.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both inductors operate across the temperature range of -55°C to 125°C, making them suitable for industrial and automotive applications requiring extended thermal operating ranges.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. "Unlimited" means these components can be stored indefinitely without special moisture control measures, simplifying inventory management and logistics.

Q: Are these parts available in other package formats?

A: Both the 4922-15L and 4922R-15L are supplied in Tape & Reel (TR) packaging format. The nonstandard package type refers to the physical form factor rather than the delivery format.
