The 5248-RC variant meets all electrical and mechanical specifications required for direct substitution. Differences in product status and compliance certifications do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 5248-RC is a direct functional equivalent to the Bourns 5248. Both components share identical electrical specifications and physical dimensions, ensuring pin-for-pin and form-factor compatibility.

The 5248-RC offers the advantage of active product status, ensuring ongoing availability and supply chain support. Additionally, the 5248-RC meets ROHS3 compliance requirements, whereas the original 5248 is RoHS non-compliant. For new designs or applications requiring regulatory compliance, the 5248-RC is the appropriate selection.

The bulk packaging option of the 5248-RC accommodates high-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 5248-RC be used as a direct replacement for the Bourns 5248?

A: Yes. The 5248-RC meets all electrical and mechanical specifications of the 5248, including inductance value, current rating, DC resistance, core material, shielding configuration, mounting type, package style, and physical dimensions. Direct substitution is functionally equivalent.

Q: What is the difference between the Bourns 5248 and 5248-RC?

A: The primary differences are product status, RoHS compliance, and packaging format. The 5248 is obsolete and RoHS non-compliant, while the 5248-RC is an active product with ROHS3 compliance. Both components are electrically and mechanically identical.

Q: Are there packaging considerations when switching from the 5248 to the 5248-RC?

A: The 5248-RC is supplied in bulk packaging, whereas the 5248 uses standard packaging. This difference affects procurement and handling but does not impact component performance or board-level integration.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both the 5248 and 5248-RC deliver identical inductance, current handling, and frequency characteristics.

Q: What are the critical parameters for substitution compatibility?

A: Inductance value (68 µH), inductance tolerance (±20%), current rating (5 A), DC resistance (54 mOhm max), core material (ferrite), shielding (unshielded), mounting type (through hole), package style (axial), and physical dimensions (0.560" Dia x 1.250" L) must remain constant for functional equivalence.
