Bourns 5522-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5522-RC is a 10 µH unshielded drum core wirewound inductor rated for 20 A continuous current with a maximum DC resistance of 6 mOhm. This through-hole component operates across the temperature range of -55°C to 105°C and is designed for radial, horizontal cylinder mounting. The 5522-RC carries an Obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The Hammond Manufacturing 1538M22 qualifies as a direct substitute for the Bourns 5522-RC based on the following critical electrical and mechanical parameters:

• Inductance value: 10 µH (identical)
• Current rating: 20 A (identical)
• DC resistance: 6 mOhm Max (identical)
• Shielding configuration: Unshielded (identical)
• Mounting type: Through Hole (identical)
• Package / Case: Radial, Horizontal Cylinder (identical)
• Physical dimensions: 0.720" Dia x 1.690" L (18.29mm x 42.93mm) (equivalent within tolerance)
• Inductance test frequency: 1 kHz (identical)

Both components are wirewound inductors with ferrite or equivalent core construction, meeting the electrical performance requirements for direct substitution in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M22 is the qualified substitute for the obsolete Bourns 5522-RC. Selection is based on:

• Electrical equivalence: Identical inductance, current rating, and DC resistance specifications
• Mechanical compatibility: Matching through-hole radial horizontal cylinder package with equivalent physical dimensions
• Regulatory compliance: Both components maintain ROHS3 and REACH compliance status
• Product availability: The 1538M22 maintains Active product status, ensuring procurement continuity and long-term supply chain stability

The Hammond 1538M22 offers improved inductance tolerance (±10% versus ±20%), providing tighter performance characteristics in applications where inductance precision is critical.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M22 be used as a direct replacement for the Bourns 5522-RC in existing designs?

A: Yes. Both components share identical electrical specifications (10 µH, 20 A, 6 mOhm DCR) and mechanical packaging (radial, horizontal cylinder through-hole). Physical dimensions are equivalent within manufacturing tolerance.

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

A: The Hammond 1538M22 provides tighter inductance tolerance (±10%) compared to the Bourns 5522-RC (±20%). Both meet identical current and resistance requirements.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status.

Q: Why is the Bourns 5522-RC listed as Obsolete?

A: The Bourns 5522-RC has reached end-of-life status. The Hammond 1538M22 remains in active production and is the recommended alternative for new designs and ongoing procurement.

Q: Will the Hammond 1538M22 fit the same PCB footprint as the Bourns 5522-RC?

A: Yes. Both components use identical through-hole radial horizontal cylinder packaging with equivalent dimensions (0.720" diameter x 1.690" length), ensuring direct mechanical compatibility on existing PCB layouts.
