API Delevan 4922-07L Equivalent & Substitute Parts

Part Overview

The API Delevan 4922-07L is a fixed unshielded drum core wirewound inductor rated at 3.3 µH with a maximum saturation current of 3.23 A and DC resistance of 38 mOhm maximum. This surface mount component operates across the temperature range of -55°C to 125°C and is specified for 1 kHz inductance testing. The part is currently in active production status with 1007 pieces available in new original inventory. Substitute parts are identified when electrical specifications, mechanical dimensions, and thermal ratings remain identical while offering improved compliance certifications or enhanced availability.

Substitute Part Grouping Explanation

Substitution of the API Delevan 4922-07L is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical inductance value (3.3 µH), inductance tolerance (±15%), current rating (3.23 A), saturation current (3.23 A), and DC resistance (38 mOhm maximum). Mechanical compatibility requires matching surface mount package dimensions (12.82 mm length × 6.09 mm width × 5.84 mm maximum seated height) and tape & reel packaging format. Thermal performance must span the full operating range of -55°C to 125°C. The core material (ferrite), shielding configuration (unshielded), and drum core wirewound construction type must remain unchanged. Substitution is permitted when these parameters are fully satisfied, regardless of differences in series designation or compliance certifications, provided the substitute part maintains active product status and equivalent availability.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 4922R-07L serves as a direct electrical and mechanical equivalent to the 4922-07L. Both parts satisfy identical inductance, current, resistance, and thermal specifications. The primary distinction is regulatory compliance: the 4922R-07L achieves ROHS3 compliance, whereas the 4922-07L is RoHS non-compliant. Selection between these parts depends on application requirements and regulatory constraints. For applications subject to RoHS3 requirements, the 4922R-07L is the appropriate choice. For applications without RoHS3 mandates, either part is electrically and mechanically interchangeable. The 4922R-07L offers higher inventory availability (1754 pieces versus 1007 pieces), which may influence procurement decisions for high-volume production. Both parts maintain active product status and identical moisture sensitivity classification (MSL 1, Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the 4922R-07L replace the 4922-07L in all applications?

A: The 4922R-07L is electrically and mechanically equivalent to the 4922-07L across all specified parameters: inductance (3.3 µH), current rating (3.23 A), DC resistance (38 mOhm), dimensions (12.82 × 6.09 × 5.84 mm), and operating temperature range (-55°C to 125°C). Substitution is valid for all applications where these electrical and mechanical specifications are required. The difference in RoHS compliance status does not affect electrical performance.

Q: What is the significance of the RoHS3 compliance difference?

A: The 4922R-07L is ROHS3 compliant, while the 4922-07L is RoHS non-compliant. This distinction is regulatory, not functional. Applications subject to RoHS3 requirements must use the 4922R-07L. Applications without RoHS3 mandates may use either part without electrical or mechanical impact.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the 4922-07L and 4922R-07L share identical surface mount package dimensions: 12.82 mm length × 6.09 mm width × 5.84 mm maximum seated height. Both are supplied in tape & reel packaging. PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the inductance tolerance for these parts?

A: Both parts carry an inductance tolerance of ±15%. This tolerance applies to the 3.3 µH nominal inductance value, resulting in an acceptable range of 2.805 µH to 3.795 µH at 1 kHz test frequency.

Q: Are there any thermal performance differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C. Thermal performance, current derating, and DC resistance characteristics are equivalent.

Q: Which part should be selected for new designs?

A: For new designs, the 4922R-07L is the preferred selection due to ROHS3 compliance, which aligns with current regulatory standards and provides future compatibility. Higher inventory availability (1754 pieces) also supports production planning. The 4922-07L remains suitable for legacy designs or applications without RoHS3 requirements.
