Parameter Comparison

Engineering Selection Recommendations

Both the 4922-37L and 4922R-37L are active production parts from API Delevan Inc. The primary distinction between these parts is their regulatory compliance status. The 4922-37L is RoHS non-compliant, while the 4922R-37L is RoHS3 compliant. Both parts maintain REACH Unaffected status and carry the same ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

For applications requiring RoHS3 compliance, the 4922R-37L is the appropriate selection. For applications without RoHS compliance requirements, either part may be used based on availability and supply chain considerations. The 4922R-37L currently maintains higher inventory levels (12,539 pcs) compared to the 4922-37L (952 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 4922R-37L replace the 4922-37L in existing designs?

A: Yes. The 4922R-37L is electrically and mechanically equivalent to the 4922-37L. All critical parameters including inductance, current rating, DC resistance, physical dimensions, and operating temperature range are identical. Direct substitution is valid at the board level.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The 4922-37L is RoHS non-compliant, while the 4922R-37L is RoHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical?

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

Q: Do these parts have the same current handling capability?

A: Yes. Both parts are rated for 240 mA continuous current with a saturation current (Isat) of 240 mA. DC resistance is specified at 6.9 Ohm maximum for both parts.

Q: Which part should I select for new designs?

A: For new designs, the 4922R-37L is recommended due to its RoHS3 compliance status, which aligns with current regulatory requirements and supply chain standards. Both parts are active in production.
