Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDPH45D13FHF-100MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (±20% tolerance band)
• Inductance test frequency: 100 kHz
• Shielding type: Shielded construction
• Core material: Ferrite
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 105°C minimum

Secondary Compatibility Factors:

• Current rating must meet or exceed 1.1 A
• DC resistance must not exceed 264 mOhm
• RoHS3 compliance required
• MSL rating of 1 or better

The CDRH4D14LDNP-100MC meets all primary matching criteria and maintains compatibility within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The CDRH4D14LDNP-100MC is a direct functional equivalent for the obsolete CDPH45D13FHF-100MC. Both components share identical inductance specifications, tolerance bands, core material, shielding configuration, and operating temperature range. The substitute part maintains ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

The CDRH4D14LDNP-100MC offers superior electrical performance characteristics: DC resistance is reduced to 135 mOhm (compared to 264 mOhm maximum), resulting in lower power dissipation. Current rating of 1.08 A is within 1.8% of the original specification. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

Physical dimensions are nearly identical, with footprint differences of less than 0.1 mm in length and width. Height variation of 0.1 mm (1.50 mm versus 1.40 mm) is negligible for standard PCB assembly applications. Packaging format change from nonstandard to Tape & Reel (TR) improves handling efficiency in automated manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the CDRH4D14LDNP-100MC be used as a direct replacement for CDPH45D13FHF-100MC?

A: Yes. Both components meet the same inductance specification (10 µH ±20%), operate at identical test frequency (100 kHz), feature ferrite shielded construction, and maintain the same operating temperature range (-40°C to 105°C). Electrical and thermal performance are compatible within circuit design parameters.

Q: What is the impact of the lower saturation current in the substitute part?

A: The CDRH4D14LDNP-100MC has a saturation current of 520 mA compared to 1.04 A in the original part. This difference is relevant only if the circuit operates at current levels between 520 mA and 1.04 A. For applications operating below 520 mA or above 1.1 A, saturation characteristics do not affect substitution eligibility.

Q: Are there physical compatibility concerns with the 0.1 mm height difference?

A: No. The height difference of 0.1 mm (1.40 mm to 1.50 mm) is within standard PCB assembly tolerances and does not affect component placement, solder joint formation, or clearance requirements in typical surface mount applications.

Q: Does the change from nonstandard to Tape & Reel packaging affect circuit performance?

A: No. Packaging format affects manufacturing logistics and component handling only. Electrical and thermal performance of the component itself remains unchanged. Tape & Reel packaging improves automated assembly efficiency.

Q: Why is the substitute part's DC resistance lower?

A: The CDRH4D14LDNP-100MC exhibits 135 mOhm maximum DC resistance versus 264 mOhm in the original part. This represents improved conductor design and is a performance advantage, resulting in reduced power dissipation and lower operating temperature under load.

Q: Is the substitute part RoHS compliant?

A: Yes. The CDRH4D14LDNP-100MC is ROHS3 compliant, matching the regulatory status of the original CDPH45D13FHF-100MC.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both components can be stored and handled under standard warehouse conditions without special desiccant packaging or baking procedures.
