Engineering Selection Recommendations

The 5725-RC is the appropriate selection for applications currently specified with the Bourns 5725. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The 5725-RC offers the advantage of active product status, ensuring long-term availability and supply chain continuity. Additionally, the 5725-RC achieves ROHS3 compliance, whereas the original 5725 is non-compliant with RoHS regulations. For new designs or redesigns of existing applications, the 5725-RC is the specified equivalent part number.

Frequently Asked Questions (FAQ)

Q: Can the 5725-RC be used as a direct replacement for the 5725?

A: Yes. The 5725-RC is electrically and mechanically equivalent to the 5725 across all specified parameters, including inductance, current rating, DC resistance, core material, shielding, mounting type, and operating temperature range.

Q: What is the primary difference between the 5725 and 5725-RC?

A: The 5725-RC is an active product with ROHS3 compliance, whereas the 5725 is obsolete and RoHS non-compliant. The 5725-RC is supplied in bulk packaging.

Q: Are there any physical dimension differences between these parts?

A: The parts differ in overall dimensions. The 5725 measures 0.875" diameter by 0.437" width (22.22mm x 11.10mm), while the 5725-RC measures 2.125" diameter by 0.937" width (53.97mm x 23.80mm). PCB layout and mounting clearance must be verified for the larger 5725-RC footprint.

Q: What compliance certifications apply to the 5725-RC?

A: The 5725-RC is ROHS3 compliant and REACH unaffected. Both parts carry the same ECCN (EAR99) and HTSUS (8504.50.4000 for the 5725-RC) classifications.

Q: Is the 5725-RC suitable for applications requiring RoHS compliance?

A: Yes. The 5725-RC meets ROHS3 compliance requirements, making it suitable for applications with RoHS mandates.
