Bourns 5516 10µH 16A Wirewound Inductor - Equivalent & Substitute Parts

Part Overview

The Bourns 5516 is a 10µH unshielded drum core wirewound inductor rated for 16A continuous current with 8mOhm maximum DC resistance. This through-hole radial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors. The 5516 is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support.

Substitute Part Grouping Explanation

Substitution for the Bourns 5516 is based on strict electrical and mechanical compatibility criteria:

Primary Substitution Criteria (Non-Negotiable):

• Inductance value: 10 µH (exact match)
• Current rating: 16 A minimum
• Mounting type: Through hole
• Package style: Radial, horizontal cylinder configuration
• Shielding: Unshielded

Secondary Compatibility Factors:

• DC resistance: 8 mOhm maximum preferred; values up to 12 mOhm acceptable if current rating and thermal performance are maintained
• Tolerance: ±20% or tighter
• Operating temperature range: Must cover -55°C to 105°C minimum
• Core material: Ferrite drum core construction

The Vishay Dale IH10EB100K meets all primary criteria and maintains electrical performance within acceptable parameters for direct substitution.

Engineering Selection Recommendations

Primary Recommendation: Vishay Dale IH10EB100K

The IH10EB100K is the direct functional equivalent for the obsolete Bourns 5516. Selection is based on the following engineering factors:

• Electrical Equivalence: Identical inductance (10 µH) and current rating (16 A) ensure drop-in compatibility for circuit performance.
• Thermal Performance: Extended operating temperature range (-55°C to 125°C) provides margin beyond the original specification.
• Compliance Status: ROHS3 compliance meets current regulatory requirements, whereas the 5516 is non-compliant.
• Production Status: Active manufacturing status ensures long-term availability and supply chain stability.
• Physical Compatibility: Matching radial horizontal cylinder package and through-hole mounting enable direct PCB layout reuse.
• Resistance Tolerance: The 4 mOhm increase in maximum DCR (8 mOhm to 12 mOhm) is within acceptable limits for most power distribution and filtering applications. Verify thermal dissipation if operating at maximum current continuously.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale IH10EB100K replace the Bourns 5516 directly on the PCB?

A: Yes. Both components use identical through-hole radial horizontal cylinder packaging. Physical footprint and lead spacing are compatible for direct substitution without PCB redesign.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The IH10EB100K has 12 mOhm maximum DCR compared to 8 mOhm for the 5516. At 16A continuous current, this results in approximately 0.768W additional power dissipation (I²R loss). Verify thermal management in your application, particularly in high-ambient-temperature environments.

Q: Does the tighter tolerance of the IH10EB100K affect circuit performance?

A: The substitute's ±10% tolerance is tighter than the original ±20% specification. This provides improved inductance consistency and may enhance circuit stability. No negative effects are expected.

Q: Is the extended temperature range of the substitute beneficial?

A: The IH10EB100K operates to 125°C versus 105°C for the 5516. This provides additional thermal margin and is beneficial for applications in elevated-temperature environments or with limited thermal management.

Q: Why is RoHS compliance important for this substitution?

A: The 5516 is RoHS non-compliant, while the IH10EB100K is ROHS3 compliant. Modern manufacturing, procurement, and export regulations increasingly require RoHS compliance. The substitute meets these requirements without performance compromise.

Q: Are there any electrical performance differences I should test?

A: Both components are unshielded drum core wirewound inductors with identical core material and inductance. Electrical behavior is equivalent. Standard circuit validation procedures apply.
