Bourns 5514-RC Equivalent & Substitute Parts

Part Overview

The Bourns 5514-RC is a 150 µH unshielded drum core wirewound inductor rated for 6.3 A with a maximum DC resistance of 46 mOhm. This through-hole component is designed for radial, horizontal cylinder mounting in applications requiring fixed inductance values with moderate current handling capability. The 5514-RC is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5514-RC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 150 µH (exact match required)
• Current Rating: 6.3 A (minimum threshold)
• DC Resistance: 46 mOhm maximum (electrical performance constraint)
• Mounting Configuration: Through-hole, radial, horizontal cylinder (mechanical compatibility)
• Physical Dimensions: 0.880" Dia x 1.620" L (PCB layout constraint)
• Shielding Type: Unshielded (electromagnetic environment requirement)
• Test Frequency: 1 kHz (measurement standard)

The Hammond Manufacturing 1538M14 meets all substitution criteria across these parameters, establishing it as a direct functional equivalent for the obsolete Bourns 5514-RC.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1538M14 is the qualified substitute for the obsolete Bourns 5514-RC. Both components maintain identical electrical specifications (150 µH inductance, 6.3 A current rating, 46 mOhm DC resistance) and mechanical form factors (0.880" Dia x 1.620" L radial horizontal cylinder). The Hammond part offers improved tolerance performance (±10% versus ±20%), providing tighter inductance control without compromising compatibility.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements. The Hammond 1538M14 is currently in active production with confirmed inventory availability (950 pcs), ensuring long-term procurement viability compared to the obsolete Bourns part.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1538M14 be used as a direct replacement for the Bourns 5514-RC in existing designs?

A: Yes. The Hammond 1538M14 matches all critical electrical and mechanical parameters: 150 µH inductance, 6.3 A current rating, 46 mOhm maximum DC resistance, and identical physical dimensions (0.880" Dia x 1.620" L). Through-hole radial mounting is identical, requiring no PCB layout modifications.

Q: What is the difference in tolerance between these parts?

A: The Bourns 5514-RC specifies ±20% inductance tolerance, while the Hammond 1538M14 specifies ±10%. The Hammond part provides tighter inductance control, which may improve circuit performance in applications sensitive to inductance variation.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory status is equivalent.

Q: Why is the Bourns 5514-RC listed as obsolete?

A: The Bourns 5514-RC belongs to the discontinued 5500 series. The Hammond 1538M14 from the active 1538 series provides functional continuity for applications requiring 150 µH unshielded wirewound inductors in this current and resistance class.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.880" diameter by 1.620" length (22.35mm x 41.15mm), ensuring identical PCB footprint and mounting compatibility.
