Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDEP149NP-1R0MC-H is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 1 µH within ±20% tolerance
• Continuous current rating of 30 A or greater
• DC resistance not exceeding 1.6 mOhm
• Saturation current (Isat) sufficient to support 30 A operation

Mechanical & Environmental Criteria:

• Surface mount package configuration
• Operating temperature range compatible with -40°C to 100°C minimum
• Nonstandard package dimensions
• Moisture sensitivity level MSL 1 (Unlimited)

Compliance Criteria:

• ROHS3 compliance required
• ECCN EAR99 classification
• HTSUS 8504.50.4000 tariff code

The substitute part PG0926.102NL meets these criteria with equivalent inductance, current rating, and compliance status, though with differences in shielding configuration and DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CDEP149NP-1R0MC-H and PG0926.102NL are Active status components with ROHS3 compliance and identical ECCN/HTSUS classifications, establishing regulatory equivalence.

Electrical Performance: The PG0926.102NL provides superior saturation current (34 A versus 26 A) and lower DC resistance (1.2 mOhm versus 1.6 mOhm maximum), resulting in reduced power dissipation and improved current handling margin.

Thermal Characteristics: The substitute part operates to 130°C, exceeding the main part's 100°C maximum, providing extended thermal headroom for applications requiring higher operating temperatures.

Physical Considerations: The PG0926.102NL occupies a smaller footprint (13.40mm x 13.40mm versus 15.20mm x 15.20mm) and lower profile (8.00mm versus 10.00mm), enabling space-constrained designs.

Shielding Difference: The main part is shielded while the substitute is unshielded. Applications requiring electromagnetic shielding for noise immunity must retain the CDEP149NP-1R0MC-H.

Frequently Asked Questions (FAQ)

Q: Can PG0926.102NL replace CDEP149NP-1R0MC-H in all applications?

A: Substitution is valid for applications where unshielded inductor operation is acceptable. If electromagnetic shielding is required for circuit performance or EMI suppression, the shielded CDEP149NP-1R0MC-H must be retained.

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

A: The PG0926.102NL has lower DC resistance (1.2 mOhm versus 1.6 mOhm maximum), resulting in reduced resistive losses and lower heat generation at rated current. This is a performance advantage in power delivery applications.

Q: Are the physical dimensions compatible?

A: The PG0926.102NL is smaller in both footprint and height. PCB layout modifications may be required if the original design was optimized for the larger CDEP149NP-1R0MC-H dimensions. Verify mechanical clearances and thermal management provisions.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, classified as EAR99, and assigned HTSUS code 8504.50.4000. Regulatory equivalence is established.

Q: What is the saturation current significance?

A: Saturation current (Isat) defines the current level at which inductance begins to degrade. The PG0926.102NL (34 A Isat) provides greater margin above the 30 A rating compared to the CDEP149NP-1R0MC-H (26 A Isat), offering improved performance stability under transient current conditions.

Q: Can the extended temperature range of PG0926.102NL be utilized?

A: The PG0926.102NL operates to 130°C, but system-level thermal limits must be observed. The extended range provides design flexibility for applications with elevated ambient or self-heating conditions, provided other circuit components support the higher temperature.
