CDRH62NP-151MC Equivalent & Substitute Parts

Part Overview

The CDRH62NP-151MC is a 150 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is rated for 280 mA continuous current with a maximum DC resistance of 2.33 Ohm and operates across the temperature range of -40°C to 100°C. The component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the CDRH62NP-151MC is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 150 µH (matching tolerance ±20%)
• Inductance test frequency: 1 kHz
• Current rating: minimum 280 mA
• DC resistance: maximum 2.33 Ohm
• Mounting type: Surface Mount
• Package dimensions: 6.60 mm × 6.20 mm (L × W), height maximum 3.00 mm
• Operating temperature range: minimum -40°C to 100°C coverage
• RoHS3 compliance
• Moisture Sensitivity Level: 1

The SPD62R-154M meets all primary substitution criteria. While this substitute exhibits improved electrical characteristics (lower DCR at 1.8 Ohm, higher current rating at 370 mA, and shielded construction), it maintains identical inductance, tolerance, package footprint, and compliance certifications. The enhanced performance parameters do not preclude substitution in applications designed for the CDRH62NP-151MC.

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-154M is a direct functional substitute for the obsolete CDRH62NP-151MC. Both components maintain identical inductance specifications, tolerance bands, and physical footprints, ensuring PCB-level compatibility without layout modifications.

Compliance and Certification Alignment: Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited shelf life), meeting regulatory requirements for current manufacturing standards.

Active Product Status: The SPD62R-154M is classified as an active product with current manufacturing support from API Delevan Inc., providing supply chain continuity and long-term availability compared to the obsolete CDRH62NP-151MC.

Performance Enhancement: The substitute part delivers improved electrical performance through reduced DC resistance (1.8 Ohm versus 2.33 Ohm maximum) and increased current saturation rating (370 mA versus 280 mA), resulting in lower power dissipation and enhanced thermal margin in the application circuit. The addition of shielding in the SPD62R-154M provides electromagnetic interference mitigation without compromising form factor or mounting compatibility.

Temperature Range Extension: The SPD62R-154M extends the operating temperature range to -55°C to 125°C, providing broader environmental coverage than the original specification of -40°C to 100°C.

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-154M be used as a direct replacement for CDRH62NP-151MC without PCB modifications?

A: Yes. Both inductors share identical package dimensions (6.60 mm × 6.20 mm footprint, 3.00 mm maximum height) and surface mount configuration, enabling direct substitution without PCB layout changes.

Q: What is the significance of the shielded construction in the SPD62R-154M compared to the unshielded CDRH62NP-151MC?

A: Shielding reduces electromagnetic field radiation and susceptibility to external interference. In applications where EMI performance is critical, the shielded SPD62R-154M provides superior noise isolation. In applications where shielding is not required, the substitute remains functionally compatible.

Q: Does the lower DC resistance of the SPD62R-154M (1.8 Ohm) affect circuit operation?

A: Lower DC resistance reduces resistive losses and heat generation. This improvement is beneficial in all applications and does not introduce compatibility issues. Circuits designed for the 2.33 Ohm maximum specification will operate within acceptable parameters with the lower resistance substitute.

Q: Are both parts available in the same packaging format?

A: The CDRH62NP-151MC is supplied in standard packaging. The SPD62R-154M is available in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. Both formats are compatible with automated pick-and-place equipment.

Q: What is the impact of the extended temperature range in the SPD62R-154M?

A: The SPD62R-154M operates from -55°C to 125°C, compared to -40°C to 100°C for the original part. This extended range provides additional margin for applications operating in extreme thermal environments and ensures compliance with broader industrial and military specifications.

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

A: Both parts are ROHS3 compliant and carry identical Moisture Sensitivity Level 1 ratings. No compliance gaps exist between the original and substitute components.
