Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDEP134-0R4NC is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part CDEP134NP-0R4NC maintains identical specifications for inductance value, current rating, saturation current, DC resistance, core material, shielding configuration, mounting type, physical dimensions, and operating temperature range. The primary distinction between the main part and its substitute is packaging format and product lifecycle status. Substitution is valid when all parameters listed in the Key Parameters table remain unchanged between the original and replacement component.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-0R4NC is the direct equivalent substitute for the obsolete CDEP134-0R4NC. Selection of the substitute part is supported by three primary factors: (1) Complete electrical parameter equivalence across inductance, current rating, saturation current, and DC resistance specifications; (2) Identical mechanical compatibility including surface mount configuration, nonstandard package type, and physical dimensions; (3) Active product status with ROHS3 compliance certification, providing superior supply chain availability and regulatory alignment compared to the obsolete original part.

The substitute part is supplied in Tape & Reel (TR) packaging format, which differs from the bulk packaging of the original part. This packaging difference does not affect electrical or mechanical performance and is standard for active production components. Organizations transitioning from CDEP134-0R4NC to CDEP134NP-0R4NC require no circuit redesign, PCB layout modification, or thermal management adjustment.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-0R4NC be used as a direct replacement for CDEP134-0R4NC in existing designs?

A: Yes. All electrical parameters including inductance value, current rating, saturation current, and DC resistance are identical. Physical dimensions and mounting type are unchanged. No circuit or layout modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product lifecycle status and packaging format. CDEP134-0R4NC is obsolete and supplied in bulk packaging. CDEP134NP-0R4NC is active production and supplied in Tape & Reel format. The "NP" designation indicates the newer packaging configuration. Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a supply and handling format only. It does not alter the electrical characteristics, thermal performance, or mechanical properties of the inductor. The component itself remains unchanged.

Q: Is CDEP134NP-0R4NC RoHS compliant?

A: Yes. CDEP134NP-0R4NC is ROHS3 compliant. The original CDEP134-0R4NC is RoHS non-compliant. If RoHS compliance is required for your application, CDEP134NP-0R4NC is the appropriate selection.

Q: Are there any other substitute options for CDEP134-0R4NC?

A: Based on the provided specifications, CDEP134NP-0R4NC is the only listed direct equivalent. This part maintains all critical electrical and mechanical parameters required for substitution.

Q: What is the current inventory status?

A: CDEP134-0R4NC has 1137 pieces in stock (obsolete status). CDEP134NP-0R4NC has 825 pieces in stock (active status). For new designs and long-term supply assurance, CDEP134NP-0R4NC is the recommended selection.
