• Inductance tolerance: ±15%
• Current rating: 2.51 A minimum
• Current saturation (Isat): 2.51 A minimum
• DC resistance: 63 mOhm maximum

Mechanical Equivalence Requirements:

• Core type: Ferrite drum core, wirewound
• Shielding configuration: Unshielded
• Mounting type: Surface mount
• Package dimensions: 0.505" L x 0.240" W (12.82 mm x 6.09 mm)
• Height seated maximum: 0.230" (5.84 mm)
• Packaging format: Tape & Reel

Environmental Equivalence Requirements:

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

The 4922R-12L meets all electrical, mechanical, and environmental equivalence criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

4922-12L Selection Criteria: The 4922-12L is suitable for applications where RoHS non-compliant components are acceptable within the design and regulatory framework. This part maintains active production status and is available in high inventory quantities (747 pcs).

4922R-12L Selection Criteria: The 4922R-12L is the preferred selection for applications requiring ROHS3 compliance. All electrical and mechanical specifications are identical to the 4922-12L. The 4922R-12L maintains active production status with significantly higher inventory availability (4992 pcs), providing superior supply chain reliability.

Both parts are manufactured by API Delevan Inc. and carry identical REACH Unaffected and EAR99 ECCN classifications. Selection between these parts should be based on regulatory compliance requirements specific to the end application and target market.

Frequently Asked Questions (FAQ)

Q: Can the 4922R-12L directly replace the 4922-12L in existing designs?

A: Yes. The 4922R-12L is electrically and mechanically identical to the 4922-12L across all specified parameters including inductance, current rating, DC resistance, core material, dimensions, and operating temperature range. PCB layout and component placement require no modification.

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

A: The primary difference is RoHS compliance status. The 4922-12L is RoHS non-compliant, while the 4922R-12L is ROHS3 compliant. All other electrical and mechanical specifications are identical.

Q: Are the package dimensions identical?

A: Yes. Both parts share identical nonstandard package dimensions of 0.505" L x 0.240" W (12.82 mm x 6.09 mm) with a maximum seated height of 0.230" (5.84 mm). Both are supplied in Tape & Reel packaging format.

Q: Do these parts have the same current handling capability?

A: Yes. Both the 4922-12L and 4922R-12L are rated for 2.51 A continuous current with identical saturation current (Isat) of 2.51 A and maximum DC resistance of 63 mOhm.

Q: What is the inductance tolerance for both parts?

A: Both parts carry an inductance tolerance of ±15% at the 1 kHz test frequency, with a nominal inductance value of 8.2 µH.

Q: Are both parts suitable for the full -55°C to 125°C temperature range?

A: Yes. Both the 4922-12L and 4922R-12L are rated for operation across the complete -55°C to 125°C temperature range with identical moisture sensitivity level (MSL) of 1 (Unlimited).

Q: Which part should be selected for new designs?

A: For new designs, the 4922R-12L is recommended due to ROHS3 compliance and higher inventory availability (4992 pcs versus 747 pcs). The 4922-12L remains suitable for applications where RoHS compliance is not a requirement.
