Substitute Part Grouping Explanation

The SPD62R-184M qualifies as a direct substitute for the SPD62-184M based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are maintained across both components:

• Inductance value: 180 µH at 1 kHz test frequency
• Inductance tolerance: ±20%
• Current rating: 350 mA
• Saturation current (Isat): 350 mA
• DC resistance: 2.1 Ohm maximum
• Core material: Ferrite with shielding
• Operating temperature range: -55°C ~ 125°C
• Physical dimensions: 0.260" L x 0.244" W (6.60mm x 6.20mm), 0.118" (3.00mm) height maximum
• Mounting configuration: Surface mount

All identified substitutes maintain these parameters without deviation, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-184M is the recommended active substitute for the obsolete SPD62-184M. Both components demonstrate identical electrical performance and physical characteristics, ensuring drop-in compatibility in surface mount applications.

The primary distinction between the two parts is product status and regulatory compliance. The SPD62-184M is classified as obsolete and carries RoHS non-compliant status, while the SPD62R-184M is an active production component with ROHS3 compliance. For new designs or long-term production requirements, the SPD62R-184M is the appropriate selection to ensure supply chain continuity and regulatory alignment.

Both components share equivalent REACH unaffected and EAR99 export classification designations. Packaging differs between the two options: the SPD62-184M utilizes nonstandard packaging, while the SPD62R-184M is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Can SPD62R-184M replace SPD62-184M in existing designs? Yes. The SPD62R-184M is a direct functional equivalent with identical electrical specifications (180 µH inductance, 350 mA current rating, 2.1 Ohm DCR maximum) and mechanical dimensions. Substitution requires no circuit modifications.

What is the primary reason to transition from SPD62-184M to SPD62R-184M? The SPD62-184M is obsolete with limited remaining inventory. The SPD62R-184M is actively manufactured and provides supply chain reliability for both new and ongoing production designs.

Are there compliance differences between these parts? The SPD62-184M is RoHS non-compliant, while SPD62R-184M is ROHS3 compliant. Both maintain REACH unaffected status. Applications subject to RoHS requirements must transition to the SPD62R-184M.

Does packaging affect part selection? SPD62-184M is supplied in nonstandard packaging, while SPD62R-184M is supplied in Tape & Reel (TR) format. The TR format is standard for high-volume automated assembly and reduces component handling time. Mechanical and electrical performance remains identical regardless of packaging format.

Are the physical dimensions identical? Yes. Both components maintain 0.260" L x 0.244" W (6.60mm x 6.20mm) lateral dimensions and 0.118" (3.00mm) maximum seated height, enabling direct PCB footprint compatibility.

What is the operating temperature range for these inductors? Both components operate across -55°C to 125°C, supporting applications in industrial, automotive, and extended-temperature environments.
