Key Parameters

Substitute Part Grouping Explanation

The SRR5028-331Y qualifies as a substitute based on the following critical parameters:

Inductance value matches at 330 µH, falling within acceptable tolerance ranges for both parts (±20% for SPD62R-334M and ±30% for SRR5028-331Y). Both components utilize ferrite core material with shielding and are rated for surface mount applications. Operating temperature ranges overlap sufficiently (-40°C to 125°C for SRR5028-331Y versus -55°C to 125°C for SPD62R-334M). Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited). Current rating differential (220 mA versus 200 mA) and DC resistance variation (3.3Ohm versus 2Ohm) represent acceptable trade-offs within the nonstandard package classification where exact mechanical and electrical matching is not required.

Parameter Comparison

Engineering Selection Recommendations

Both SPD62R-334M and SRR5028-331Y maintain active product status with full ROHS3 and REACH compliance. Selection between these parts should be based on application-specific current requirements and thermal performance needs. The SPD62R-334M supports higher saturation current (220 mA) and operates across a wider temperature minimum (-55°C versus -40°C). The SRR5028-331Y offers lower DC resistance (2Ohm versus 3.3Ohm), reducing power dissipation in applications where this characteristic is beneficial. Both components are available in production quantities and meet identical regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can SRR5028-331Y replace SPD62R-334M in all applications?

A: Substitution is valid where the application current requirement does not exceed 200 mA and the minimum operating temperature does not fall below -40°C. The lower saturation current of the SRR5028-331Y must be evaluated against circuit requirements.

Q: What is the significance of the DC resistance difference?

A: The SPD62R-334M has 3.3Ohm maximum DC resistance compared to 2Ohm maximum for SRR5028-331Y. Lower resistance reduces I²R losses. Applications sensitive to power dissipation or thermal performance may benefit from the lower resistance characteristic of the substitute part.

Q: Are the physical dimensions compatible?

A: Both parts share identical seated height (0.118" / 3.00mm). Footprint dimensions differ slightly: SPD62R-334M measures 0.260" x 0.244" (6.60mm x 6.20mm) while SRR5028-331Y measures 0.228" x 0.228" (5.80mm x 5.80mm). PCB layout verification is required to confirm mechanical fit.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SPD62R-334M and SRR5028-331Y are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What inductance tolerance should be expected?

A: SPD62R-334M carries ±20% tolerance while SRR5028-331Y carries ±30% tolerance. Both parts are specified at 330 µH nominal, with the wider tolerance of the substitute part requiring circuit validation if inductance precision is critical.
