API Delevan 4922-48L Equivalent & Substitute Parts

Part Overview

The API Delevan 4922-48L is a fixed surface mount inductor featuring an 8.2 mH unshielded drum core wirewound design. This component is rated for 77 mA maximum current with a 66 Ohm maximum DC resistance and operates across the temperature range of -55°C to 125°C. The part is currently active in production and available in tape and reel packaging for automated assembly processes. Identifying equivalent substitute parts is necessary when primary inventory is unavailable or when design requirements mandate compliance with specific regulatory standards such as RoHS.

Substitute Part Grouping Explanation

The API Delevan 4922R-48L qualifies as a direct substitute for the 4922-48L based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria: inductance value of 8.2 mH with ±15% tolerance, current rating of 77 mA, DC resistance of 66 Ohm maximum, ferrite drum core construction, unshielded configuration, surface mount technology, nonstandard package dimensions, and operating temperature range of -55°C to 125°C.

The substitution is valid based on the following key parameters:

Inductance: 8.2 mH (identical)
Current Rating: 77 mA (identical)
DC Resistance: 66 Ohm Max (identical)
Core Type: Ferrite drum core, wirewound (identical)
Shielding: Unshielded (identical)
Physical Dimensions: 0.505" L x 0.240" W x 0.230" H max (identical)
Temperature Range: -55°C to 125°C (identical)
Mounting: Surface mount, tape and reel (identical)

Engineering Selection Recommendations

Both the 4922-48L and 4922R-48L are active production parts from API Delevan Inc. with identical electrical and mechanical specifications. The primary distinction between these parts is regulatory compliance status. The 4922-48L is RoHS non-compliant, while the 4922R-48L achieves ROHS3 compliance. Both parts maintain REACH Unaffected status and share the same ECCN and HTSUS classifications.

Selection between these parts should be based on design requirements for regulatory compliance. Applications requiring RoHS3 compliance must use the 4922R-48L. Applications without RoHS compliance mandates may use either part based on availability and supply chain considerations. Both parts are suitable for surface mount assembly in tape and reel format and deliver equivalent electrical performance across the specified operating temperature range.
