Bourns 4632-RC Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 4632-RC is a 100 µH unshielded drum core wirewound inductor rated for 400 mA with a maximum DC resistance of 3Ohm. Designed for through-hole axial mounting, this component operates across a temperature range of -55°C to 105°C and is compliant with RoHS3 and REACH standards.

The 4632-RC is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this inductance value and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 4632-RC is determined by the following critical parameters:

• Inductance Value: 100 µH (exact match required)
• Current Rating: 400 mA minimum
• DC Resistance: 3Ohm maximum
• Mounting Configuration: Through-hole axial package
• Physical Dimensions: 0.290" Dia x 0.875" L (7.37mm x 22.22mm)
• Shielding Type: Unshielded
• Self-Resonant Frequency: 12 MHz
• Regulatory Compliance: RoHS3 and REACH compliance

The Hammond Manufacturing 1532H meets all critical electrical and mechanical parameters required for direct substitution. Tolerance variation (±10% vs ±5%) remains within acceptable limits for most applications where the 4632-RC is deployed.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 1532H is a direct electrical and mechanical substitute for the obsolete Bourns 4632-RC. Both components satisfy identical inductance, current, and resistance specifications. The Hammond part maintains active product status, ensuring ongoing availability and supply chain stability.

Both parts carry ROHS3 and REACH compliance certifications, meeting regulatory requirements for modern electronics manufacturing. The tolerance difference (±10% vs ±5%) does not preclude substitution in applications where the original 4632-RC was specified, as the Hammond part operates within the same functional envelope.

Physical compatibility is confirmed through identical axial package dimensions and through-hole mounting configuration, allowing direct board-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Hammond 1532H replace the Bourns 4632-RC in existing designs?

A: Yes. The Hammond 1532H matches all critical electrical parameters (inductance, current rating, DC resistance) and physical dimensions. Direct substitution is supported without circuit redesign.

Q: Does the tolerance difference (±10% vs ±5%) affect compatibility?

A: The Hammond part's ±10% tolerance remains within acceptable operating margins for applications originally designed around the 4632-RC. Circuit performance is maintained across the specified tolerance band.

Q: Are there any compliance or certification differences?

A: Both parts carry identical RoHS3 and REACH compliance status. No regulatory barriers exist to substitution.

Q: Will the Hammond 1532H fit the same PCB footprint?

A: Yes. Both components share identical axial package dimensions (0.290" Dia x 0.875" L) and through-hole mounting configuration. No board layout changes are required.

Q: What is the availability status of each part?

A: The Bourns 4632-RC is obsolete. The Hammond 1532H maintains active product status with confirmed inventory availability, making it the recommended choice for new procurement and design continuity.
