Equivalent & Substitute Parts for Bourns 4626-RC

Part Overview

The Bourns 4626-RC is a 24 µH unshielded drum core wirewound inductor rated for 800 mA with a maximum DC resistance of 340 mOhm. This component is designed for through-hole axial mounting applications requiring fixed inductance in the 24 µH range. The 4626-RC is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 4626-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 24 µH
• Current rating: 800 mA minimum
• DC resistance: 340 mOhm maximum
• Shielding configuration: Unshielded
• Mounting type: Through hole axial
• Physical form factor: 0.290" diameter x 0.875" length

The Hammond Manufacturing 1532C meets all these core electrical and mechanical requirements, establishing it as a direct functional equivalent for the obsolete Bourns 4626-RC.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1532C is the qualified substitute for the Bourns 4626-RC based on electrical and mechanical parameter equivalence. The 1532C is an active product with current manufacturing support, addressing the obsolescence status of the original component. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The primary difference is inductance tolerance: the 4626-RC specifies ±5% while the 1532C specifies ±10%. Applications requiring tighter tolerance control must evaluate whether the ±10% specification of the 1532C remains acceptable for circuit performance. All other electrical parameters, including current rating, DC resistance, Q factor, and self-resonant frequency, are equivalent or identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1532C directly replace the Bourns 4626-RC in existing designs?

A: Yes, the Hammond 1532C meets all core electrical and mechanical specifications. The primary consideration is the inductance tolerance difference (±10% versus ±5%). Designs that do not require the tighter tolerance of the original part can proceed with direct substitution.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical axial form factors: 0.290" diameter x 0.875" length (7.37mm x 22.22mm). Through-hole PCB mounting compatibility is maintained.

Q: What is the significance of the inductance tolerance difference?

A: The Bourns 4626-RC specifies ±5% tolerance while the Hammond 1532C specifies ±10%. In circuits where inductance value directly affects performance (resonant frequency, filtering characteristics, impedance matching), the wider tolerance of the 1532C may introduce measurable variation. Circuit analysis should confirm acceptable performance across the ±10% range.

Q: Are compliance certifications equivalent?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for environmental and hazardous substance requirements.

Q: Why is the Bourns 4626-RC obsolete?

A: The 4626-RC is classified as obsolete by the manufacturer. The Hammond 1532C is an active product with ongoing production and supply availability, making it the recommended path for new designs and ongoing procurement.
