Engineering Selection Recommendations

Primary Selection Criteria:

The 4922R-31L serves as the direct substitute for the 4922-31L based on complete electrical and mechanical equivalence. Both parts are manufactured by API Delevan Inc. and maintain identical specifications across all critical parameters including inductance, current rating, DC resistance, physical dimensions, and operating temperature range.

Compliance Consideration:

The 4922R-31L offers ROHS3 compliance status, whereas the 4922-31L is classified as RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 4922R-31L is the appropriate selection. For applications without RoHS compliance requirements, either part is functionally equivalent.

Inventory Availability:

The 4922R-31L currently maintains higher inventory availability at 2541 pieces compared to 1161 pieces for the 4922-31L. This inventory differential may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Functional Equivalence:

Both parts are classified as active products with identical product status. No functional or performance differentiation exists between the 4922-31L and 4922R-31L for applications requiring 330 µH inductance at 390 mA current rating with 2.51 Ohm maximum DC resistance in surface mount nonstandard packaging.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-31L be used as a direct replacement for the 4922-31L in existing designs?
