Bourns 5502-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5502-RC is a 10 µH unshielded drum core wirewound inductor rated for 9 A continuous current with a maximum DC resistance of 17 mOhm. Designed for through-hole radial mounting, this component operates across the temperature range of -55°C to 105°C. The 5502-RC carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the Bourns 5502-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 10 µH
• Current rating: 9 A minimum
• DC resistance: 17 mOhm maximum
• Mounting configuration: Through-hole radial, horizontal cylinder
• Physical dimensions: 0.630" diameter × 1.120" length
• Shielding classification: Unshielded
• Inductance measurement frequency: 1 kHz

The Hammond Manufacturing 1538M02 meets all substitution criteria. While the 1538M02 specifies a tighter tolerance of ±10% compared to the 5502-RC's ±20%, this represents an improvement in performance consistency and does not restrict compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M02 is a direct functional equivalent to the obsolete Bourns 5502-RC. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current production environments. The 1538M02 carries active product status, providing supply chain continuity and long-term availability.

The Hammond 1538M02 demonstrates superior tolerance specification (±10% versus ±20%), which enhances circuit performance predictability without introducing compatibility concerns. All electrical and mechanical parameters align precisely with the original 5502-RC specification.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M02 be used as a direct replacement for the Bourns 5502-RC in existing designs?

A: Yes. The 1538M02 matches all critical electrical parameters (inductance, current rating, DC resistance) and physical dimensions. Through-hole radial mounting configuration and package dimensions are identical, enabling direct PCB footprint compatibility.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: The Hammond 1538M02's tighter ±10% tolerance represents improved inductance value consistency. This does not restrict substitution; rather, it provides enhanced performance stability in applications sensitive to inductance variation.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. No regulatory barriers exist to substitution.

Q: Why is the Bourns 5502-RC listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Hammond 1538M02, with active product status, provides a supported alternative for ongoing design and production requirements.

Q: Are the physical dimensions truly identical?

A: Yes. Both components specify 0.630" diameter × 1.120" length (16.00mm × 28.45mm), ensuring identical PCB mounting footprint and spatial requirements.
