Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPD62R-104M is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 100 µH (core electrical function)
• Core type: Ferrite drum core, wirewound (magnetic performance)
• Shielding: Shielded configuration (EMI containment)
• Mounting: Surface mount, nonstandard package (PCB integration)

Secondary Compatibility Criteria:

• Current rating: Minimum 410 mA saturation current
• DC resistance: Maximum 1.6 Ohm (thermal and efficiency constraints)
• Operating temperature: Overlap with -55°C to 125°C range
• RoHS3 compliance and MSL rating (regulatory and reliability)

The SRR5028-101Y manufactured by Bourns Inc. qualifies as a substitute based on matching inductance, core material, shielding type, and surface mount configuration. Variations in current rating, DC resistance, tolerance, and temperature range are within acceptable engineering substitution parameters for this component category.

Engineering Selection Recommendations

SPD62R-104M (Primary Component):

• Active product status with established supply chain (971 pcs in stock)
• RoHS3 compliant and REACH unaffected
• Suitable for applications requiring -55°C minimum operating temperature
• Lower DC resistance (1.6 Ohm) appropriate for higher power dissipation tolerance

SRR5028-101Y (Substitute Component):

• Active product status with higher inventory availability (5000 pcs in stock)
• RoHS3 compliant and REACH unaffected
• Operating temperature minimum of -40°C; suitable for standard industrial and commercial applications
• Superior current handling (450 mA vs 410 mA) and significantly lower DC resistance (480 mOhm vs 1.6 Ohm)
• Smaller footprint (5.80mm x 5.80mm vs 6.60mm x 6.20mm) may provide PCB layout advantages
• Wider inductance tolerance (±30%) requires verification in tolerance-sensitive circuits

Both components meet regulatory compliance requirements. Selection between primary and substitute should be based on application-specific requirements for operating temperature range, DC resistance performance, and PCB space constraints.

Frequently Asked Questions (FAQ)

Q: Can SRR5028-101Y replace SPD62R-104M in all applications?

A: Substitution is valid for applications operating at -40°C or above. Applications requiring -55°C minimum temperature operation must use the SPD62R-104M. Both components provide identical 100 µH inductance and shielded ferrite drum core construction.

Q: What is the significance of the DC resistance difference (1.6 Ohm vs 480 mOhm)?

A: DC resistance affects power dissipation and thermal performance. The SRR5028-101Y exhibits significantly lower resistance, resulting in reduced heat generation at equivalent current levels. Applications sensitive to inductor heating may benefit from the substitute part.

Q: Does the package size difference affect PCB compatibility?

A: The SRR5028-101Y is physically smaller (5.80mm x 6.20mm vs 6.60mm x 6.20mm) with identical height (3.00mm). PCB footprint compatibility must be verified against the specific circuit board design. Smaller size may allow improved layout density.

Q: How do inductance tolerances affect circuit performance?

A: SPD62R-104M specifies ±20% tolerance while SRR5028-101Y specifies ±30%. In circuits where inductance value precision is critical (resonant circuits, filters), the tighter tolerance of the primary component may be required. Standard applications typically accommodate ±30% variation.

Q: Are both components suitable for high-reliability applications?

A: Both components carry RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. Both are classified as Active products. Component selection for high-reliability applications should include assessment of manufacturer qualification, supply chain stability, and application-specific environmental requirements.

Q: What is the difference in current rating significance?

A: SPD62R-104M is rated for 410 mA saturation current; SRR5028-101Y is rated for 450 mA. The substitute provides 40 mA additional current capacity. Applications operating near the 410 mA limit may benefit from the higher-rated substitute component.
