Parameter Comparison

Engineering Selection Recommendations

The API Delevan 4922R-21L serves as a direct electrical and mechanical equivalent to the 4922-21L. Both components are manufactured by API Delevan Inc. and maintain identical specifications across all critical parameters: inductance value, current rating, DC resistance, core material, physical dimensions, and operating temperature range.

The primary distinction between these parts is regulatory compliance status. The 4922R-21L achieves ROHS3 compliance, whereas the 4922-21L is classified as RoHS non-compliant. For applications subject to RoHS directives or procurement policies requiring RoHS compliance, the 4922R-21L is the appropriate selection.

Both components share identical REACH and ECCN classifications, confirming equivalent regulatory treatment in these categories. The 4922R-21L also demonstrates superior inventory availability with 1294 pieces in stock compared to 852 pieces for the 4922-21L.

Selection between these parts should be based on compliance requirements specific to the application or procurement specification. From an electrical and mechanical standpoint, either part performs identically within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Are the 4922-21L and 4922R-21L electrically interchangeable?

A: Yes. Both components feature identical inductance values (47 µH), current ratings (1.04 A), DC resistance specifications (362 mOhm maximum), and operating temperature ranges (-55°C to 125°C). They are direct electrical equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 4922R-21L is ROHS3 compliant, while the 4922-21L is RoHS non-compliant. All other electrical, mechanical, and environmental specifications are identical.

Q: Can I use the 4922R-21L as a replacement for the 4922-21L in existing designs?

A: Yes. The 4922R-21L maintains identical physical dimensions (0.505" L x 0.240" W, height 0.230" maximum), mounting type (surface mount), and packaging format (Tape & Reel). No PCB layout or assembly process modifications are required.

Q: Are there any performance differences between these inductors?

A: No. Both parts are specified with identical inductance tolerance (±15%), saturation current (1.04 A), and core material (ferrite, unshielded drum core). Performance characteristics are equivalent.

Q: Which part should I specify for new designs?

A: Selection depends on compliance requirements. For applications requiring RoHS compliance, specify the 4922R-21L. For applications without RoHS requirements, either part is acceptable. The 4922R-21L offers the advantage of improved regulatory compliance and higher current inventory availability.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both the 4922-21L and 4922R-21L are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these parts have identical export classifications?

A: Yes. Both components share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications, confirming equivalent export and tariff treatment.
