CDEP134-1R8MC-H Equivalent & Substitute Parts

Part Overview

The CDEP134-1R8MC-H is a 1.8 µH shielded wirewound inductor manufactured by Sumida America Components Inc., rated for 10.5 A continuous current with a maximum DC resistance of 6.6 mOhm. This surface mount component operates across the temperature range of -40°C to 100°C and is designed for applications requiring controlled inductance with low DC resistance characteristics.

The CDEP134-1R8MC-H carries an obsolete product status. Locating equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for legacy systems or redesign initiatives.

Substitute Part Grouping Explanation

Substitute parts for the CDEP134-1R8MC-H are identified based on strict electrical and mechanical parameter matching within the CDEP134 series. The substitution criteria are:

Electrical Parameters (Must Match):

• Inductance value: 1.8 µH
• Inductance tolerance: ±20%
• Current rating: 10.5 A
• Saturation current: 17.6 A
• DC resistance: 6.6 mOhm maximum
• Shielding: Shielded configuration

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Physical footprint: 13.50 mm × 13.50 mm
• Height: 5.00 mm maximum seated height
• Package classification: Nonstandard

Environmental Parameters (Must Match):

• Moisture sensitivity level: 1 (Unlimited)
• Inductance test frequency: 100 kHz

Substitute parts may differ in product status, packaging format, core material composition, and compliance certifications, provided all electrical and mechanical parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

The CDEP134NP-1R8MC-H is a direct electrical and mechanical equivalent to the obsolete CDEP134-1R8MC-H. All critical inductance, current, resistance, and dimensional specifications are identical. The substitute part is manufactured by the same supplier and belongs to the same CDEP134 series.

Key Advantages of CDEP134NP-1R8MC-H:

The substitute part carries active product status, ensuring ongoing availability and supply chain support. The CDEP134NP-1R8MC-H achieves ROHS3 compliance, whereas the original part is non-compliant. The operating temperature range extends to 125°C, providing a 25°C margin above the original specification of 100°C maximum. The substitute is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly processes.

Compatibility Considerations:

Both parts share identical electrical performance at the specified 100 kHz test frequency. The physical footprint and height are unchanged, ensuring direct PCB layout compatibility. The ferrite core material specified in the substitute part maintains the shielded wirewound inductor characteristics required for the application.

The substitute part is suitable for direct replacement in new production runs, redesign initiatives, or legacy system support where the original CDEP134-1R8MC-H is no longer available.

Frequently Asked Questions (FAQ)

Q: Can CDEP134NP-1R8MC-H be used as a direct replacement for CDEP134-1R8MC-H?

A: Yes. Both parts have identical inductance (1.8 µH), current rating (10.5 A), DC resistance (6.6 mOhm maximum), physical dimensions (13.50 × 13.50 mm), and height (5.00 mm). All critical electrical and mechanical parameters match specification.

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

A: The primary differences are product status and packaging. CDEP134-1R8MC-H is obsolete with nonstandard packaging, while CDEP134NP-1R8MC-H is active with Tape & Reel (TR) packaging. The substitute also includes ferrite core material specification and ROHS3 compliance.

Q: Does the extended temperature range of CDEP134NP-1R8MC-H affect circuit performance?

A: No. The extended operating range (-40 to 125°C versus -40 to 100°C) provides additional margin without changing electrical characteristics within the original specification limits.

Q: Are there any compliance differences between the two parts?

A: Yes. CDEP134NP-1R8MC-H is ROHS3 compliant, while CDEP134-1R8MC-H is non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Is the packaging format change from nonstandard to Tape & Reel significant?

A: The Tape & Reel (TR) format of CDEP134NP-1R8MC-H is standard for automated surface mount assembly. This improves handling efficiency and supply chain compatibility compared to nonstandard packaging.

Q: What is the saturation current specification, and why is it important?

A: Both parts have a saturation current (Isat) of 17.6 A. This represents the current level at which the inductor begins to lose inductance due to core saturation. The 10.5 A continuous rating provides a 1.68× safety margin below saturation.

Q: Are there any restrictions on using CDEP134NP-1R8MC-H in legacy designs?

A: No electrical or mechanical restrictions exist. The substitute part is fully compatible with designs originally specified for CDEP134-1R8MC-H. Verify that ROHS3 compliance is acceptable for your application requirements.
