Engineering Selection Recommendations

The CDEP105NP-1R4MC-88 is the direct substitute for the obsolete CDEP105-1R4MC-88. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts is determined by the following factors:

Product Status: The CDEP105-1R4MC-88 is classified as obsolete. The CDEP105NP-1R4MC-88 maintains active product status with 9,456 units in stock, compared to 740 units of the obsolete variant. For new designs and ongoing production, the active part number is the appropriate choice.

Regulatory Compliance: The CDEP105NP-1R4MC-88 is ROHS3 compliant, while the CDEP105-1R4MC-88 is RoHS non-compliant. Applications subject to RoHS directives or customer requirements for RoHS compliance must use the CDEP105NP-1R4MC-88.

Packaging Format: The CDEP105-1R4MC-88 is supplied in bulk packaging. The CDEP105NP-1R4MC-88 is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Selection depends on manufacturing process requirements and volume considerations.

Electrical and Mechanical Equivalence: Both parts share identical electrical specifications (1.4 µH inductance, 13 A rating, 4.1 mOhm DCR) and mechanical dimensions (10.00 mm × 10.00 mm × 5.60 mm). Direct substitution is valid without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the CDEP105NP-1R4MC-88 be used as a direct replacement for the CDEP105-1R4MC-88?

A: Yes. Both parts are electrically and mechanically equivalent. The CDEP105NP-1R4MC-88 is the active production equivalent with identical inductance (1.4 µH), current rating (13 A), DC resistance (4.1 mOhm), and physical dimensions. No circuit modifications are required.

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

A: The primary differences are product status, packaging format, and RoHS compliance. The CDEP105-1R4MC-88 is obsolete and supplied in bulk. The CDEP105NP-1R4MC-88 is active, supplied in Tape & Reel format, and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Which part should be specified for new designs?

A: The CDEP105NP-1R4MC-88 should be specified for new designs. It is the active production part with superior availability (9,456 units in stock) and meets current RoHS3 compliance requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical footprints (10.00 mm × 10.00 mm) and maximum seated height (5.60 mm). PCB layout and component placement are fully compatible.

Q: What is the saturation current specification?

A: Both parts have a saturation current (Isat) of 12 A. The continuous current rating is 13 A. Design margins must account for the 1 A difference between continuous and saturation ratings.
