Substitute Part Grouping Explanation

The SRR5028-2R6Y by Bourns Inc. qualifies as a substitute for the SPD62R-242M based on the following substitution criteria:

Allowed Parameter Variance:

• Inductance: 2.6 µH (nominal) versus 2.4 µH (nominal) — within acceptable tolerance range accounting for the ±20% specification of the primary part and ±30% specification of the substitute
• Current Rating: 3 A versus 2.8 A — substitute exceeds the primary part requirement
• DC Resistance: 30 mOhm Max versus 100 mOhm Max — substitute provides superior performance with lower resistance
• Shielding: Both parts are shielded drum core wirewound inductors
• Core Material: Both utilize ferrite core construction
• Mounting: Both are Surface Mount components
• Environmental Compliance: Both achieve ROHS3 compliance

The substitute maintains electrical function within the design margins while offering improved current handling and reduced resistive losses.

Parameter Comparison

Engineering Selection Recommendations

Both the SPD62R-242M and SRR5028-2R6Y are Active production parts with full ROHS3 compliance and unlimited moisture sensitivity ratings. The SRR5028-2R6Y offers operational advantages through superior DC resistance (30 mOhm versus 100 mOhm) and higher current rating (3 A versus 2.8 A), while maintaining compatible inductance values within specified tolerances. Board layout considerations must account for the dimensional difference: the Bourns component is smaller in footprint (5.80mm x 5.80mm versus 6.60mm x 6.20mm). The lower operating temperature minimum of the substitute (-40°C versus -55°C) may impose constraints in applications requiring extended cold-temperature operation below -40°C.

Frequently Asked Questions (FAQ)

Q: What are the primary electrical parameters that determine substitution compatibility?

A: Inductance value, current rating, DC resistance, and shielding type are the critical parameters. The SRR5028-2R6Y maintains inductance within acceptable tolerance variance while exceeding current and resistance specifications of the SPD62R-242M.

Q: Are there mechanical constraints when substituting the SRR5028-2R6Y for the SPD62R-242M?

A: Both components share identical height (3.00mm), but the Bourns part has a smaller footprint (5.80mm x 5.80mm versus 6.60mm x 6.20mm). Board layout and trace routing must accommodate this dimensional difference.

Q: What temperature range limitations apply to the substitute part?

A: The SRR5028-2R6Y operates from -40°C to 125°C, compared to -55°C to 125°C for the original part. Applications requiring operation below -40°C must retain the SPD62R-242M.

Q: Do both parts meet regulatory compliance requirements?

A: Both components are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity ratings (MSL 1), meeting equivalent regulatory standards.

Q: How does the DC resistance difference affect circuit performance?

A: The substitute's lower DC resistance (30 mOhm versus 100 mOhm) reduces power dissipation and heat generation, potentially improving thermal performance in current-limited applications.
