Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPD62R-823M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 82 µH (exact match required)
• Shielding type: Shielded drum core configuration
• Core material: Ferrite
• Mounting type: Surface Mount (SMD)
• Package type: Nonstandard drum core form factor

Secondary Compatibility Criteria:

• Current rating: Minimum 500 mA (equal or greater acceptable)
• DC resistance: Lower values preferred for reduced losses
• Operating temperature range: Minimum -55°C ~ 125°C coverage
• Compliance: ROHS3 and REACH status alignment

The substitute part SRR5028-820Y from Bourns Inc. meets all primary matching criteria with 82 µH inductance, shielded ferrite drum core construction, and surface mount configuration. Secondary parameters show acceptable variance within engineering tolerances for this component category.

Engineering Selection Recommendations

SPD62R-823M Selection Criteria:

• Applications requiring operating temperature range of -55°C to 125°C
• Designs with inductance tolerance specification of ±20% or tighter
• Circuits where DC resistance of 1.45 Ohm maximum is specified
• PCB layouts accommodating 6.60mm x 6.20mm footprint

SRR5028-820Y Selection Criteria:

• Applications operating within -40°C to 125°C temperature range
• Designs benefiting from lower DC resistance (430 mOhm) for reduced power dissipation
• Space-constrained layouts where 5.80mm x 5.80mm footprint provides advantage
• Current ratings up to 520 mA acceptable for application requirements
• Inductance tolerance of ±30% acceptable for circuit design

Both parts maintain Active product status and full ROHS3 and REACH compliance, ensuring long-term availability and regulatory alignment. Selection between these components depends on specific thermal, spatial, and electrical loss requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can SRR5028-820Y directly replace SPD62R-823M in all applications?

A: Direct replacement is possible when the application tolerates the following parameter differences: operating temperature minimum of -40°C (versus -55°C), inductance tolerance of ±30% (versus ±20%), and reduced DC resistance of 430 mOhm (versus 1.45 Ohm). The smaller footprint (5.80mm x 5.80mm versus 6.60mm x 6.20mm) must be verified against PCB layout constraints.

Q: What is the impact of the lower DC resistance in SRR5028-820Y?

A: Lower DC resistance reduces resistive losses and heat generation in the inductor. For applications where power dissipation is a concern, SRR5028-820Y provides improved efficiency. However, this parameter difference does not affect inductance value or current handling capability.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging and are classified as Nonstandard package types. Height when seated is identical at 3.00mm maximum. The primary difference is the planar footprint dimension.

Q: What compliance certifications apply to both parts?

A: Both SPD62R-823M and SRR5028-820Y are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: How do inductance tolerances affect circuit performance?

A: SPD62R-823M specifies ±20% tolerance while SRR5028-820Y specifies ±30% tolerance. In applications where inductance value directly affects circuit frequency response, filtering characteristics, or impedance matching, the tighter tolerance of SPD62R-823M may be required. Verify circuit design specifications before substitution.

Q: Is the current saturation rating identical between these parts?

A: Yes, both parts specify 500 mA saturation current (Isat). This parameter represents the current level at which inductance begins to degrade due to core saturation and is identical for both components.
