Parameter Comparison

Engineering Selection Recommendations

The DI2220V301R-10 is the direct active equivalent for the obsolete DI2220V301R-00. Selection of the substitute part is based on the following engineering criteria:

Product Status: The DI2220V301R-10 maintains Active product status, ensuring continued availability and manufacturer support. The original DI2220V301R-00 is classified as Obsolete, creating supply chain risk for ongoing production and field replacements.

Compliance & Certifications: The DI2220V301R-10 is ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets. The original part is RoHS non-compliant, which may restrict its use in new designs subject to RoHS directives.

Electrical & Mechanical Equivalence: All critical electrical parameters (inductance, current rating, DC resistance, core material, shielding) and mechanical parameters (footprint, mounting type, operating temperature range) are identical between the two parts.

Packaging Consideration: The DI2220V301R-10 is supplied in standard Tape & Reel (TR) packaging, compared to the nonstandard packaging of the original part. This facilitates automated assembly processes and improves supply chain efficiency.

Physical Dimension Variance: The seated height differs by 0.26 mm (3.60 mm vs. 3.86 mm). This minor variation must be evaluated against specific PCB layout and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the DI2220V301R-10 be used as a direct replacement for the DI2220V301R-00 in existing designs?

A: Yes, the DI2220V301R-10 is electrically and mechanically equivalent. All critical parameters including inductance, current rating, DC resistance, core material, and physical footprint are identical. The 0.26 mm difference in seated height must be verified against PCB clearance specifications.

Q: What is the primary reason for substituting the DI2220V301R-00?

A: The DI2220V301R-00 is classified as Obsolete, creating supply chain discontinuity. The DI2220V301R-10 is an Active product with identical electrical specifications and improved compliance status (ROHS3).

Q: Are there any compliance differences between these parts?

A: Yes. The DI2220V301R-10 is ROHS3 compliant, while the DI2220V301R-00 is RoHS non-compliant. For applications subject to RoHS regulations, the DI2220V301R-10 is the required choice.

Q: How do the packaging formats differ?

A: The DI2220V301R-00 uses nonstandard packaging, while the DI2220V301R-10 is supplied in standard Tape & Reel (TR) format. Standard packaging improves compatibility with automated assembly equipment and supply chain logistics.

Q: Is the height difference between the two parts significant?

A: The DI2220V301R-10 has a maximum seated height of 0.152" (3.86 mm) compared to 0.142" (3.60 mm) for the DI2220V301R-00, a difference of 0.26 mm. This must be evaluated against specific PCB layout, component clearance, and enclosure height constraints in the target application.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts are 300 nH inductors with ±10% tolerance, 8 A current rating, 10 mOhm maximum DC resistance, ferrite core material, unshielded configuration, and 25 MHz test frequency. Operating temperature range is identical at -40°C to 125°C.

Q: What inventory status should be considered for procurement?

A: The DI2220V301R-00 has 24,100 pieces in stock (obsolete status), while the DI2220V301R-10 has 17,400 pieces in stock (active status). For new designs and long-term production, the DI2220V301R-10 is the appropriate selection due to active product status and continued manufacturer support.
