Substitute Part Grouping Explanation

The API Delevan 4922R-53L qualifies as a direct substitute for the 4922-53L based on identical electrical specifications and mechanical compatibility. Substitution is determined by the following critical parameters:

• Inductance value: 22 mH with ±15% tolerance
• Current rating and saturation current: 50 mA
• DC resistance: 160 Ohm maximum
• Core material and shielding configuration: Ferrite, unshielded
• Operating temperature range: -55°C to 125°C
• Physical dimensions and mounting: Surface mount, nonstandard package with identical footprint (0.505" L x 0.240" W, 0.230" max height)
• Inductance test frequency: 1 kHz

Both parts are manufactured by API Delevan Inc. and maintain identical electrical performance and physical compatibility. The substitute part differs in product compliance status and series designation.

Parameter Comparison

Engineering Selection Recommendations

The 4922R-53L serves as a direct electrical and mechanical substitute for the 4922-53L. Both parts maintain identical inductance, current ratings, DC resistance, core material, temperature operating range, and physical dimensions. Selection between these parts should be based on compliance requirements and product status:

The 4922-53L is RoHS non-compliant, while the 4922R-53L achieves ROHS3 compliance. Applications subject to RoHS directives or requiring compliant component documentation should specify the 4922R-53L. Both parts carry active product status and unlimited moisture sensitivity rating (MSL 1), indicating no special storage or handling requirements. REACH and export classification (EAR99) are identical across both parts.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-53L replace the 4922-53L in existing designs?

A: Yes. The 4922R-53L is electrically and mechanically identical to the 4922-53L. Both parts feature 22 mH inductance at ±15% tolerance, 50 mA current rating, 160 Ohm maximum DC resistance, ferrite core construction, and identical physical dimensions (0.505" L x 0.240" W x 0.230" max height). Surface mount footprint and tape & reel packaging are identical.

Q: What is the primary difference between these two parts?

A: The 4922R-53L is ROHS3 compliant, while the 4922-53L is RoHS non-compliant. All electrical specifications and mechanical parameters are identical.

Q: Are there any temperature or current derating considerations?

A: Both parts operate across -55°C to 125°C with a 50 mA maximum current rating and 50 mA saturation current. No additional derating information is provided in the component specifications.

Q: What is the DC resistance specification, and how does it affect circuit design?

A: Both parts specify 160 Ohm maximum DC resistance. This parameter must be considered in circuit calculations where inductor resistance contributes to overall impedance and power dissipation.

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

A: Inductance is tested at 1 kHz. Self-resonant frequency data is not provided in the component specifications. Applications requiring operation at frequencies significantly above 1 kHz should be evaluated based on actual circuit performance requirements.

Q: What packaging and handling requirements apply to these inductors?

A: Both parts are supplied in Tape & Reel (TR) format with MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control or baking requirements during storage or assembly.
