API Delevan 4922-22L Fixed Inductor Equivalent & Substitute Parts

Part Overview

The API Delevan 4922-22L is a fixed unshielded drum core wirewound inductor rated at 56 µH with 1 A current capacity and 397 mOhm maximum DC resistance. This surface mount component operates across the temperature range of -55°C to 125°C and is designed for applications requiring stable inductance values in compact nonstandard packages.

The 4922-22L is classified as an active product with 627 pieces currently in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative sourcing, compliance status, or inventory availability necessitates component substitution.

Substitute Part Grouping Explanation

Substitution of the API Delevan 4922-22L is permissible with the 4922R-22L based on strict electrical and mechanical equivalence. The substitution logic is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 56 µH
• Inductance tolerance: ±15%
• Current rating: 1 A
• Saturation current: 1 A
• DC resistance: 397 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package type: Nonstandard
• Physical dimensions: 0.505" L × 0.240" W (12.82 mm × 6.09 mm)
• Maximum seated height: 0.230" (5.84 mm)
• Packaging format: Tape & Reel (TR)

Operating Conditions (Must Match):

• Temperature range: -55°C to 125°C
• Inductance test frequency: 1 kHz

The 4922R-22L maintains complete electrical and mechanical equivalence to the 4922-22L, differing only in product series designation and compliance certifications.

Engineering Selection Recommendations

Primary Selection (4922-22L): The 4922-22L is the original specified component and remains the primary selection for applications where RoHS non-compliance is acceptable or where legacy component qualification is required. Current inventory of 627 pieces supports immediate procurement.

Substitute Selection (4922R-22L): The 4922R-22L is a direct electrical and mechanical equivalent that provides ROHS3 compliance, addressing regulatory requirements for applications subject to RoHS directives. The 4922R-22L is preferred for new designs or applications requiring RoHS3 certification. Significantly higher inventory availability (4144 pieces) ensures supply continuity and reduces lead time risk.

Both components are classified as active products from API Delevan Inc. and maintain identical electrical performance, thermal characteristics, and mechanical compatibility. Selection between these parts is determined by compliance requirements and inventory availability rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-22L replace the 4922-22L in existing designs?

A: Yes. The 4922R-22L is electrically and mechanically equivalent to the 4922-22L. All critical parameters including inductance (56 µH), current rating (1 A), DC resistance (397 mOhm maximum), core material (ferrite), physical dimensions (0.505" × 0.240" × 0.230" maximum height), and operating temperature range (-55°C to 125°C) are identical. The components are interchangeable at the circuit level.

Q: What is the primary difference between these two parts?

A: The 4922R-22L is ROHS3 compliant, while the 4922-22L is RoHS non-compliant. Both parts are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications. The series designation differs (4922 versus 4922R), and inventory levels vary.

Q: Are there any package or mounting differences?

A: No. Both components use identical nonstandard packages, surface mount configuration, and Tape & Reel (TR) packaging format. Physical dimensions, seated height, and all mechanical parameters are identical.

Q: Which part should be selected for new product designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 4922R-22L is the appropriate choice. For applications without RoHS requirements, either part is suitable. Both are active products with stable supply.

Q: Are the inductance tolerances identical?

A: Yes. Both the 4922-22L and 4922R-22L maintain ±15% inductance tolerance at 1 kHz test frequency.

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

A: Both components are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any thermal performance differences?

A: No. Both components operate across the identical temperature range of -55°C to 125°C with no performance degradation differences.
