Substitute Part Grouping Explanation

Substitution eligibility for the CDEP134CNP-1R2MC-75 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance value: 1.2 µH
• Inductance tolerance: ±20%
• Current rating: 15 A minimum
• Saturation current (Isat): 21 A minimum
• DC resistance (DCR): 3.7 mOhm maximum
• Core material: Ferrite
• Operating temperature range: -40°C to 125°C minimum

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Physical footprint: 13.50 mm × 13.50 mm
• Height seated maximum: 4.90 mm or less
• Package classification: Nonstandard

Compliance Criteria:

• RoHS3 compliance required
• Moisture sensitivity level: MSL 1 (Unlimited)

The substitute part CDEP134NP-1R2MC-H meets all electrical and mechanical equivalence criteria. The primary distinction is the transition from unshielded to shielded construction and from obsolete to active product status, with packaging available in Tape & Reel format.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-1R2MC-H is a direct functional equivalent to the obsolete CDEP134CNP-1R2MC-75. Both components share identical electrical specifications across inductance, current rating, saturation current, and DC resistance parameters. The physical footprint and mounting type are equivalent, with the substitute part exhibiting a seated height of 5.00 mm compared to 4.90 mm for the original part—a 0.10 mm difference that remains within typical PCB design tolerances for surface mount applications.

The CDEP134NP-1R2MC-H is manufactured by the same supplier and maintains full RoHS3 compliance and MSL 1 rating. The transition from unshielded to shielded construction represents an enhancement in electromagnetic isolation characteristics. The substitute part is actively produced and available in standard Tape & Reel packaging, eliminating supply chain constraints associated with the obsolete original part.

Selection of the CDEP134NP-1R2MC-H is supported by product status transition from obsolete to active, maintained compliance certifications, and verified electrical and mechanical parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can the CDEP134NP-1R2MC-H replace the CDEP134CNP-1R2MC-75 in existing designs?

A: Yes. The substitute part meets all critical electrical parameters: 1.2 µH inductance, 15 A current rating, 21 A saturation current, and 3.7 mOhm maximum DC resistance. Physical dimensions are equivalent at 13.50 mm × 13.50 mm footprint. The seated height difference of 0.10 mm (5.00 mm versus 4.90 mm) is within standard PCB design clearance tolerances for surface mount applications.

Q: What is the primary difference between these two parts?

A: The CDEP134CNP-1R2MC-75 is unshielded and obsolete. The CDEP134NP-1R2MC-H is shielded and actively produced. Both share identical electrical specifications and core material composition. Shielding provides enhanced electromagnetic isolation in applications where EMI/RFI performance is relevant.

Q: Is the shielded construction of the substitute part compatible with my application?

A: Shielded construction is functionally compatible with applications designed for unshielded inductors. Shielding reduces electromagnetic field radiation and improves EMI performance. No design modification is required for direct substitution.

Q: What packaging formats are available for the substitute part?

A: The CDEP134NP-1R2MC-H is supplied in Tape & Reel (TR) packaging, the standard format for surface mount production environments. The original part packaging format is not specified in available documentation.

Q: Are both parts RoHS compliant?

A: Yes. Both the CDEP134CNP-1R2MC-75 and CDEP134NP-1R2MC-H are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the original part listed as obsolete?

A: The CDEP134CNP-1R2MC-75 is classified as obsolete by the manufacturer. The CDEP134NP-1R2MC-H represents the active production equivalent, ensuring continued supply availability and manufacturer support.
