Substitute Part Grouping Explanation

Substitution of the CDEP134-0R3NC-H is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 300 nH at 100 kHz test frequency
• Inductance tolerance: ±30%
• Current rating: 18.5 A minimum
• Saturation current: 35 A minimum
• DC resistance: 1.9 mOhm maximum
• Core material: Ferrite
• Shielding: Shielded configuration

Mechanical Equivalence Requirements:

• Mounting type: Surface mount
• Package dimensions: 13.50 mm x 13.50 mm x 5.00 mm maximum
• Core type: Drum core wirewound
• Operating temperature range: -40°C to 125°C minimum

The CDEP134NP-0R3NC-H meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute for the obsolete CDEP134-0R3NC-H.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-0R3NC-H is the qualified substitute for the obsolete CDEP134-0R3NC-H based on complete electrical and mechanical parameter equivalence. All critical specifications including inductance, current rating, saturation current, DC resistance, core material, shielding, dimensions, and operating temperature range are identical between the two parts.

The substitute part offers additional advantages:

Product Status: The CDEP134NP-0R3NC-H maintains active product status with Sumida America Components Inc., ensuring continued availability and supply chain reliability compared to the obsolete main part.

Regulatory Compliance: The substitute part is ROHS3 compliant, meeting current environmental and regulatory requirements. The main part is RoHS non-compliant and may present compliance challenges in new designs or applications subject to RoHS directives.

Packaging Format: The substitute is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The main part was supplied in bulk format. This packaging difference does not affect electrical or mechanical performance and is compatible with standard pick-and-place equipment.

Inventory Availability: The substitute part has 868 pieces in new original stock, providing immediate availability for production requirements.

For applications requiring the CDEP134-0R3NC-H, direct substitution with CDEP134NP-0R3NC-H is appropriate without circuit redesign or performance compromise.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-0R3NC-H be used as a direct replacement for CDEP134-0R3NC-H?

A: Yes. The CDEP134NP-0R3NC-H is a direct substitute. All electrical parameters (inductance, current rating, saturation current, DC resistance) and mechanical specifications (dimensions, core material, shielding, mounting type) are identical. No circuit modifications are required.

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

A: The primary differences are product status and packaging format. The CDEP134-0R3NC-H is obsolete and supplied in bulk packaging. The CDEP134NP-0R3NC-H is an active product supplied in Tape & Reel format and is ROHS3 compliant. The "NP" designation in the substitute part number indicates the updated packaging and compliance status.

Q: Are there any performance differences between these parts?

A: No. Both parts are manufactured by Sumida America Components Inc. from the same CDEP134 series and deliver identical electrical performance. The inductance value, current handling capability, DC resistance, and frequency response are equivalent.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the industry standard for automated surface mount assembly. It is compatible with standard pick-and-place equipment and reflow soldering processes. If your process requires bulk packaging, the substitute part can be manually loaded or transferred to bulk containers.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. RoHS3 compliance is a regulatory advantage and does not affect electrical or mechanical compatibility. If your application or end market requires RoHS compliance, the substitute part meets this requirement while the main part does not.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling. Standard component storage practices are sufficient.

Q: Can I mix inventory of both parts in production?

A: Yes. Since the parts are electrically and mechanically identical, they can be used interchangeably in the same circuit. However, for traceability and compliance documentation, it is recommended to track which part number is used in each production batch.
