Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPD62R-683M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value of 68 µH (tolerance variations acceptable within design margin)
• Shielded drum core wirewound construction
• Ferrite core material
• Surface mount package configuration
• Current rating sufficient for 560 mA operation
• Operating temperature range compatibility (-55°C to 125°C minimum)
• ROHS3 compliance and REACH unaffected status

Secondary Compatibility Factors:

• DC resistance characteristics (lower DCR values provide improved efficiency)
• Physical dimensions permitting board layout accommodation
• Saturation current rating at or above 560 mA

The SRR5028-680Y from Bourns Inc. meets these substitution criteria through equivalent inductance specification, matching shielding and core material, compatible current handling, and identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

SPD62R-683M Selection Criteria:

• Applications requiring extended low-temperature operation below -40°C
• Designs where larger footprint (6.60mm x 6.20mm) is acceptable
• Circuits tolerating higher DC resistance (1.2 Ohm maximum)
• Supply chain preference for API Delevan inventory

SRR5028-680Y Selection Criteria:

• Applications prioritizing reduced power dissipation through lower DC resistance (350 mOhm)
• Designs with space constraints benefiting from smaller footprint (5.80mm x 5.80mm)
• Higher current margin applications (620 mA rating vs. 560 mA requirement)
• Supply chain preference for Bourns inventory

Both components maintain Active product status, ROHS3 compliance, and REACH unaffected classification, ensuring regulatory and environmental compatibility for current and future manufacturing requirements.

Frequently Asked Questions (FAQ)

Q: Can SRR5028-680Y directly replace SPD62R-683M in existing designs?

A: Direct substitution is functionally viable for circuits operating within -40°C to 125°C temperature range. The SRR5028-680Y provides superior DC resistance characteristics (350 mOhm vs. 1.2 Ohm), reducing power dissipation. Physical footprint difference (5.80mm x 5.80mm vs. 6.60mm x 6.20mm) requires PCB layout verification. Inductance tolerance widening (±30% vs. ±20%) must be evaluated against circuit performance margins.

Q: What are the DC resistance implications for circuit performance?

A: The SRR5028-680Y exhibits significantly lower DC resistance (350 mOhm maximum) compared to SPD62R-683M (1.2 Ohm maximum). This 3.4x reduction decreases resistive losses and heat generation, improving efficiency in current-limited applications. Circuits designed with the higher resistance value will experience improved performance with the substitute part.

Q: Are there temperature range limitations for substitution?

A: SPD62R-683M operates from -55°C to 125°C, while SRR5028-680Y operates from -40°C to 125°C. Substitution is restricted for applications requiring operation below -40°C. Both components maintain performance within the overlapping -40°C to 125°C range.

Q: How do inductance tolerance differences affect circuit design?

A: SPD62R-683M specifies ±20% tolerance while SRR5028-680Y specifies ±30% tolerance. Circuits with tight inductance requirements must account for the wider tolerance band of the substitute part. Both components meet the 68 µH nominal specification within their respective tolerance windows.

Q: What packaging and inventory considerations apply?

A: Both components are supplied in Tape & Reel (TR) packaging suitable for automated assembly. SPD62R-683M inventory: 2275 pieces. SRR5028-680Y inventory: 1138 pieces. Component selection should consider supply availability and lead time requirements.

Q: Are compliance certifications equivalent between parts?

A: Both SPD62R-683M and SRR5028-680Y maintain identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited), and ECCN EAR99 classification. Regulatory and environmental requirements are satisfied by either component.
