Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4922-29L is determined by strict equivalence across the following critical parameters:

• Inductance value: 220 µH with ±15% tolerance
• Current rating: 500 mA continuous, 500 mA saturation current
• DC resistance: 1.58 Ohm maximum
• Core material and type: Ferrite, drum core wirewound construction
• Shielding configuration: Unshielded
• Physical dimensions: 0.505" L x 0.240" W x 0.230" H maximum
• Mounting technology: Surface mount
• Operating temperature range: -55°C ~ 125°C
• Packaging format: Tape & Reel

The API Delevan 4922R-29L qualifies as a direct substitute based on identical electrical performance, mechanical compatibility, and package specifications. The primary distinction between the main part and substitute relates to regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 4922-29L and 4922R-29L maintain Active product status and are manufactured by API Delevan Inc. with identical electrical and mechanical specifications. The 4922R-29L is ROHS3 compliant, whereas the 4922-29L is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For designs subject to RoHS3 directives or equivalent environmental compliance standards, the 4922R-29L is the appropriate selection. For applications without RoHS compliance mandates, either part satisfies the electrical and mechanical requirements. Both components maintain REACH Unaffected status and are suitable for the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-29L be used as a direct replacement for the 4922-29L in existing designs?

A: Yes. The 4922R-29L is electrically and mechanically equivalent to the 4922-29L. Both components feature identical inductance (220 µH ±15%), current rating (500 mA), DC resistance (1.58 Ohm max), core material (ferrite), physical dimensions (0.505" L x 0.240" W x 0.230" H max), and operating temperature range (-55°C ~ 125°C). The primary difference is RoHS compliance status.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 4922R-29L is ROHS3 compliant, while the 4922-29L is RoHS non-compliant. RoHS3 compliance indicates the component meets restrictions on hazardous substances as defined by applicable environmental regulations. Selection depends on whether the end application or market requires RoHS compliance certification.

Q: Are the physical dimensions and mounting characteristics identical?

A: Yes. Both parts are surface mount inductors with nonstandard package specifications. Dimensions are 0.505" L x 0.240" W with a maximum seated height of 0.230" (12.82mm x 6.09mm x 5.84mm). Both are supplied in Tape & Reel packaging and are compatible with standard surface mount assembly processes.

Q: Do these parts have different thermal or frequency characteristics?

A: No. Both components operate across the same temperature range (-55°C ~ 125°C) and are tested at 1 kHz inductance frequency. No differences in thermal performance or frequency response are specified.

Q: What inventory considerations apply to these substitute parts?

A: The 4922-29L has 688 pieces in stock, while the 4922R-29L has 4420 pieces in stock. Availability may influence component selection for high-volume production requirements.
