Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4922-09L is determined by strict equivalence across the following critical parameters:

• Inductance value: 4.7 µH at 1 kHz test frequency
• Inductance tolerance: ±15%
• Current rating: 2.9 A minimum
• Saturation current (Isat): 2.9 A minimum
• DC resistance: 47 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Component type: Drum core, wirewound
• Mounting: Surface mount
• Physical dimensions: 0.505" L x 0.240" W (12.82 mm x 6.09 mm)
• Height seated maximum: 0.230" (5.84 mm)
• Operating temperature range: -55°C to 125°C
• Packaging format: Tape & Reel

The 4922R-09L meets all these criteria and qualifies as a direct substitute. Both parts belong to the API Delevan 4922 series family and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 4922R-09L is a qualified direct substitute for the 4922-09L based on complete electrical and mechanical parameter equivalence. Both components are active products from API Delevan and maintain identical specifications across inductance, current rating, DC resistance, core material, shielding, mounting configuration, and physical dimensions.

A key distinction exists in regulatory compliance: the 4922-09L is RoHS non-compliant, while the 4922R-09L achieves ROHS3 compliance. For applications subject to RoHS directives or environmental regulations requiring lead-free construction, the 4922R-09L is the appropriate selection. For legacy systems or applications without RoHS requirements, either part is functionally equivalent.

The 4922R-09L also offers superior inventory availability with 7185 pieces in stock compared to 969 pieces for the 4922-09L, providing better supply chain assurance for production planning.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-09L replace the 4922-09L in existing designs?

A: Yes. The 4922R-09L is electrically and mechanically identical to the 4922-09L. All critical parameters including inductance (4.7 µH), current rating (2.9 A), DC resistance (47 mOhm max), core material (ferrite), shielding (unshielded), and physical dimensions (0.505" L x 0.240" W, 0.230" height max) are equivalent. Direct substitution is possible without circuit redesign.

Q: What is the difference between the 4922-09L and 4922R-09L?

A: The primary difference is RoHS compliance status. The 4922-09L is RoHS non-compliant, while the 4922R-09L is ROHS3 compliant. All electrical and mechanical specifications are identical. The 4922R-09L also has higher inventory availability.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 4922-09L and 4922R-09L operate across -55°C to 125°C, making them interchangeable for temperature-dependent applications.

Q: Does the packaging format differ between these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging format, ensuring compatibility with standard pick-and-place assembly equipment.

Q: Which part should be selected for new designs?

A: For new designs, the 4922R-09L is recommended due to ROHS3 compliance, which aligns with current environmental regulations and provides better long-term supply chain sustainability. The higher inventory level also supports production scheduling.

Q: Are there any mechanical compatibility concerns when substituting?

A: No. Both parts share identical nonstandard package dimensions and mounting specifications, ensuring mechanical compatibility on PCB layouts designed for either component.
