Substitute Part Grouping Explanation

Substitute parts for the CDEP134-3R6MC are identified based on strict electrical and mechanical parameter matching within the CDEP134 series. The substitution criteria are:

Electrical Parameters (Must Match):

• Inductance value: 3.6 µH
• Inductance tolerance: ±20%
• Current rating: 8 A
• Current saturation (Isat): 10.9 A
• DC resistance (DCR): 10.8 mOhm Max
• Shielding: Shielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Package / Case: Nonstandard
• Size / Dimension: 0.531" L x 0.531" W (13.50 mm x 13.50 mm)
• Height - Seated (Max): 0.197" (5.00 mm)

Test Conditions (Must Match):

• Inductance frequency test: 100 kHz

Environmental Parameters (Must Match or Exceed):

• Operating temperature range: -40°C ~ 100°C minimum
• Moisture sensitivity level: 1 (Unlimited)

The CDEP134NP-3R6MC qualifies as a direct substitute because it maintains all critical electrical specifications, identical physical dimensions, and compatible environmental ratings while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-3R6MC is the direct substitute for the obsolete CDEP134-3R6MC based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters are identical, including inductance value (3.6 µH), current rating (8 A), saturation current (10.9 A), and DC resistance (10.8 mOhm Max). Both components are shielded and tested at 100 kHz.

Mechanical Compatibility: Physical dimensions and mounting characteristics are identical. Both components feature the same nonstandard package configuration with dimensions of 0.531" L x 0.531" W (13.50 mm x 13.50 mm) and maximum seated height of 0.197" (5.00 mm). Surface mount compatibility is maintained.

Environmental Performance: The CDEP134NP-3R6MC extends the operating temperature range to -40°C ~ 125°C, providing enhanced thermal capability compared to the original -40°C ~ 100°C specification. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating.

Product Status and Compliance: The CDEP134NP-3R6MC holds active product status with ROHS3 compliance, addressing regulatory requirements and ensuring long-term supply chain availability. The original CDEP134-3R6MC is obsolete and RoHS non-compliant.

Supply Availability: The substitute part maintains significantly higher inventory levels (2200 Pcs vs. 775 Pcs), supporting production continuity and reducing procurement risk.

Frequently Asked Questions (FAQ)

Q: Can the CDEP134NP-3R6MC be used as a direct replacement for the CDEP134-3R6MC in existing designs?

A: Yes. The CDEP134NP-3R6MC is electrically and mechanically equivalent to the CDEP134-3R6MC. All critical specifications including inductance (3.6 µH), current rating (8 A), DC resistance (10.8 mOhm Max), and physical dimensions (0.531" x 0.531" x 0.197" max height) are identical. The substitute part is compatible with existing PCB layouts and circuit designs.

Q: What is the difference between the core materials of these two inductors?

A: The CDEP134-3R6MC core material is not specified in the available documentation. The CDEP134NP-3R6MC uses a ferrite drum core construction. Despite this construction difference, both components deliver identical electrical performance at the specified test frequency of 100 kHz and maintain the same DC resistance and current ratings.

Q: Does the extended operating temperature range of the CDEP134NP-3R6MC affect compatibility?

A: No. The CDEP134NP-3R6MC extends the operating temperature range to -40°C ~ 125°C, which encompasses the original specification of -40°C ~ 100°C. This enhancement provides additional thermal margin and does not compromise compatibility with designs specified for the original temperature range.

Q: What packaging format is available for the substitute part?

A: The CDEP134NP-3R6MC is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. The original CDEP134-3R6MC packaging format is not specified in the available data.

Q: Are there any compliance differences between these parts?

A: Yes. The CDEP134NP-3R6MC is ROHS3 compliant, while the CDEP134-3R6MC is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the CDEP134NP-3R6MC is the appropriate selection.

Q: How do the inductance tolerance specifications compare?

A: Both components share identical inductance tolerance of ±20%, ensuring equivalent circuit performance and design margin in applications requiring this specification.

Q: Is the saturation current specification the same for both parts?

A: Yes. Both the CDEP134-3R6MC and CDEP134NP-3R6MC have a saturation current (Isat) of 10.9 A, providing identical current handling capability and design headroom above the 8 A continuous rating.
