API Delevan 4922-18L Fixed Inductor Equivalent & Substitute Parts

Part Overview

The API Delevan 4922-18L is a 27 µH unshielded drum core wirewound inductor rated for 1.48 A with a maximum DC resistance of 179 mOhm. This surface mount component operates across the temperature range of -55°C to 125°C and is packaged in a nonstandard case measuring 0.505" L x 0.240" W (12.82mm x 6.09mm). The part is currently active in production. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the 4922-18L are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Inductance value: 27 µH with ±15% tolerance
• Current rating and saturation current: 1.48 A minimum
• DC resistance: 179 mOhm maximum
• Core material and type: Ferrite, drum core, wirewound construction
• Shielding configuration: Unshielded
• Physical dimensions: 0.505" L x 0.240" W (12.82mm x 6.09mm), height 0.230" (5.84mm) maximum
• Mounting type: Surface mount
• Operating temperature range: -55°C to 125°C
• Packaging: Tape & Reel (TR)

Only parts meeting all of these parameters are classified as direct substitutes. Variations in any parameter disqualify a part from this equivalence group.

Parameter Comparison

Engineering Selection Recommendations

Both the 4922-18L and 4922R-18L are active production parts from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction is regulatory compliance status. The 4922R-18L is ROHS3 compliant, while the 4922-18L is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99.

Selection between these parts depends on application requirements and regulatory obligations. Applications subject to RoHS directives should specify the 4922R-18L. Applications without RoHS requirements may use either part. Both parts maintain identical performance characteristics across all electrical parameters, physical dimensions, and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-18L replace the 4922-18L in all applications?

A: Yes, from an electrical and mechanical standpoint. The 4922R-18L is electrically and physically identical to the 4922-18L. The difference is RoHS compliance status. If your application or region does not mandate RoHS compliance, either part is functionally equivalent. If RoHS compliance is required, the 4922R-18L must be used.

Q: What is the difference between the 4922 and 4922R series designations?

A: The series designation reflects manufacturing and compliance variations. Both series produce the same electrical and mechanical specifications for the 27 µH inductor. The "R" designation in 4922R indicates ROHS3 compliance.

Q: Are the physical dimensions identical between 4922-18L and 4922R-18L?

A: Yes. Both parts measure 0.505" L x 0.240" W (12.82mm x 6.09mm) with a maximum seated height of 0.230" (5.84mm). They are packaged identically in Tape & Reel format and mount identically on PCBs.

Q: What is the inductance tolerance for these parts?

A: Both parts have an inductance tolerance of ±15% at the 1 kHz test frequency. This tolerance applies to the 27 µH nominal value.

Q: Can these inductors be used in high-temperature applications?

A: Yes. Both the 4922-18L and 4922R-18L are rated for operation across -55°C to 125°C. This temperature range supports most industrial and commercial applications.

Q: What is the saturation current specification?

A: The saturation current (Isat) for both parts is 1.48 A, matching the current rating. This indicates the inductor reaches saturation at its rated current level.

Q: Is shielding available for these inductors?

A: No. Both the 4922-18L and 4922R-18L are unshielded drum core inductors. If shielding is required, alternative part numbers must be evaluated.
