API Delevan 4922-23L Fixed Inductor Equivalent & Substitute Parts

Part Overview

The API Delevan 4922-23L is a 68 µH unshielded drum core wirewound inductor rated for 970 mA continuous current with a maximum DC resistance of 418 mOhm. This surface mount component operates across the industrial temperature range of -55°C to 125°C and is specified for 1 kHz inductance testing. The part is currently active in production. Substitute parts are identified to address packaging format availability, compliance requirements, and inventory considerations while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The 4922R-23L is identified as a direct substitute for the 4922-23L based on matching electrical and mechanical parameters. Substitution is valid where the following criteria are met:

• Inductance value: 68 µH with ±15% tolerance
• Current rating: 970 mA continuous and saturation current
• DC resistance: 418 mOhm maximum
• Core type: Ferrite drum core, unshielded
• Operating temperature: -55°C to 125°C
• Physical dimensions: 0.505" L x 0.240" W x 0.230" H maximum
• Mounting: Surface mount, nonstandard package
• Test frequency: 1 kHz

The primary distinction between these parts is packaging format and RoHS compliance status. The 4922-23L is supplied in Tape & Reel (TR) format and is RoHS non-compliant. The 4922R-23L is available in Cut Tape (CT) and Digi-Reel® formats with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the 4922-23L and 4922R-23L are active production parts with identical electrical performance and mechanical compatibility. Selection between these parts should be based on the following factors:

The 4922R-23L offers ROHS3 compliance, making it suitable for applications subject to RoHS Directive requirements. The 4922-23L remains available for applications where RoHS compliance is not mandated.

Packaging format differs between the two parts. The 4922-23L is supplied in Tape & Reel (TR) format, while the 4922R-23L is available in Cut Tape (CT) and Digi-Reel® formats. Selection should align with assembly equipment capabilities and procurement workflows.

Both parts maintain REACH Unaffected status and carry EAR99 export classification. Moisture sensitivity level 1 (Unlimited) applies to both, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-23L replace the 4922-23L in existing designs?

A: Yes. The 4922R-23L is electrically and mechanically identical to the 4922-23L. All specified parameters including inductance, current rating, DC resistance, temperature range, and physical dimensions are equivalent. Substitution is valid for direct component replacement.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) is a continuous reel format used for high-volume automated assembly. Cut Tape (CT) consists of individual component segments cut from the reel, suitable for lower-volume orders or manual assembly. Digi-Reel® is a proprietary packaging format. Selection depends on assembly volume and equipment compatibility.

Q: Does the 4922R-23L RoHS3 compliance affect electrical performance?

A: No. RoHS3 compliance is a material composition requirement that does not alter the electrical specifications, inductance value, current rating, or DC resistance of the component. Performance remains identical to the non-compliant 4922-23L.

Q: Are there any temperature or frequency limitations when substituting these parts?

A: No. Both parts operate identically across the -55°C to 125°C temperature range and are specified for 1 kHz inductance testing. No additional limitations apply to substitution.

Q: What is the moisture sensitivity level for these inductors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. Standard storage and handling practices apply without special environmental controls.
