Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4554R-2R2M is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 2.2 µH
• Tolerance: ±20%
• Current rating: 6.5 A
• DC resistance: 21 mOhm maximum
• Q factor: 20 @ 7.96 MHz

Mechanical Parameters (Must Match):

• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Shielding: Unshielded

Compliance Parameters (Must Match):

• RoHS3 compliance
• REACH unaffected status

The substitute part RLB9012-2R2ML from Bourns Inc. meets all critical electrical and mechanical requirements. Variations in physical dimensions, operating temperature range, self-resonant frequency, and inductance test frequency do not affect functional substitution within the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 4554R-2R2M and RLB9012-2R2ML are active production components with full ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications. Selection between these parts is based on availability and packaging preference:

The 4554R-2R2M is supplied in bulk packaging with 683 pieces currently in stock. The RLB9012-2R2ML is supplied in tray packaging with 1119 pieces in stock, offering higher inventory availability. Both parts satisfy identical electrical and mechanical specifications for through-hole PCB assembly applications requiring 2.2 µH inductance at 6.5 A current rating.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-2R2ML replace the 4554R-2R2M in existing designs?

A: Yes. Both parts meet identical electrical specifications (2.2 µH, ±20% tolerance, 6.5 A, 21 mOhm DCR) and mechanical requirements (through-hole, radial vertical cylinder package). Physical dimensions differ slightly but do not affect PCB layout compatibility for standard through-hole mounting.

Q: What is the difference between bulk and tray packaging?

A: Bulk packaging is supplied without individual component trays, while tray packaging organizes components in segmented trays for automated assembly. Both packaging types contain the same electrical component. Selection depends on assembly process requirements and handling procedures.

Q: Are there temperature range differences between these parts?

A: The 4554R-2R2M operates from -40°C to 85°C, while the RLB9012-2R2ML operates from -55°C to 125°C. For applications within the -40°C to 85°C range, both parts are functionally equivalent. Applications requiring extended temperature operation should specify the RLB9012-2R2ML.

Q: Do these inductors have identical self-resonant frequencies?

A: No. The 4554R-2R2M has a self-resonant frequency of 100 MHz, while the RLB9012-2R2ML has 90 MHz. For applications operating below 90 MHz, both parts are suitable. Applications requiring operation near or above 90 MHz should verify frequency-dependent performance characteristics.

Q: What inductance test frequency is used for these parts?

A: The 4554R-2R2M is tested at 7.96 MHz, while the RLB9012-2R2ML is tested at 1 kHz. Both achieve the specified 2.2 µH inductance value within ±20% tolerance at their respective test frequencies.
