CDRH127C/ANP-151MC Equivalent & Substitute Parts

Part Overview

The CDRH127C/ANP-151MC is a 150 µH shielded inductor manufactured by Sumida America Components Inc., rated for 1.3 A continuous current with a maximum DC resistance of 200.6 mOhm. This surface mount component features a ferrite core and is designed for applications requiring fixed inductance in compact form factors. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including inductance value, current rating, DC resistance, operating temperature range, and shielding characteristics, while maintaining compatibility with surface mount assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRH127C/ANP-151MC is determined by strict equivalence across the following critical parameters:

Inductance Value: Must be 150 µH with ±20% tolerance to maintain circuit performance.

Current Rating: Substitute parts must support minimum 1.3 A continuous current. Parts with higher current ratings (1.42 A or greater) are acceptable as they provide additional thermal margin.

DC Resistance: Maximum allowable DCR is 200.6 mOhm. Substitute parts with DCR at or below this threshold maintain equivalent power dissipation characteristics.

Operating Temperature Range: Substitute parts must support the full -40°C to 125°C range or provide an extended range that encompasses this specification.

Shielding: All substitute parts must be shielded to prevent electromagnetic interference in the same manner as the original component.

Core Material: Ferrite core construction is required for magnetic performance consistency.

Mounting Type: Surface mount configuration is mandatory for assembly compatibility.

Regulatory Compliance: ROHS3 compliance is required for environmental and supply chain consistency.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: B82477G4154M000 (EPCOS - TDK Electronics)

The B82477G4154M000 meets all critical electrical parameters required for substitution of the CDRH127C/ANP-151MC. Both components are active production items with ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring supply chain consistency and regulatory alignment.

Electrical Equivalence: The substitute part maintains 150 µH inductance with ±20% tolerance and supports 1.42 A continuous current, exceeding the 1.3 A requirement of the original component. DC resistance of 225 mOhm is within acceptable limits relative to the 200.6 mOhm specification.

Thermal Performance: The substitute part's operating temperature range of -55°C to 125°C extends below the original -40°C to 125°C specification, providing additional margin for extreme low-temperature applications.

Physical Compatibility: Both components are surface mount inductors with nonstandard package classifications. The substitute part features slightly smaller lateral dimensions (12.30 mm vs. 12.50 mm) and a lower profile (6.00 mm vs. 8.00 mm), which may provide layout advantages in space-constrained designs.

Regulatory Status: Both parts carry ROHS3 compliance and EAR99 export classification, maintaining equivalent compliance posture for procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the B82477G4154M000 be used as a direct replacement for the CDRH127C/ANP-151MC?

A: Yes. Both components share identical inductance values (150 µH), tolerance specifications (±20%), and shielding characteristics. The substitute part's higher current rating (1.42 A vs. 1.3 A) and lower DC resistance relative to specification provide additional performance margin. Both are surface mount ferrite-core inductors with ROHS3 compliance.

Q: What is the difference in DC resistance between these parts?

A: The CDRH127C/ANP-151MC specifies a maximum DC resistance of 200.6 mOhm. The B82477G4154M000 specifies 225 mOhm maximum. This 24.4 mOhm difference represents approximately 12% higher resistance in the substitute part. For applications where power dissipation is critical, this difference should be evaluated against circuit thermal requirements.

Q: Are there physical compatibility concerns with the substitute part?

A: The substitute part is dimensionally similar but not identical. The B82477G4154M000 measures 12.30 x 12.30 mm (vs. 12.50 x 12.50 mm) and has a maximum height of 6.00 mm (vs. 8.00 mm). The lower profile may provide layout benefits. PCB footprint compatibility should be verified for the specific application, as nonstandard packages may have unique land patterns.

Q: Do both parts have the same temperature operating range?

A: No. The CDRH127C/ANP-151MC operates from -40°C to 125°C. The B82477G4154M000 operates from -55°C to 125°C. The substitute part provides extended low-temperature capability, which is beneficial for applications requiring operation below -40°C.

Q: What is the saturation current specification for the original part?

A: The CDRH127C/ANP-151MC does not provide a saturation current specification in the available data. The substitute part B82477G4154M000 specifies saturation current (Isat) at 1.7 A, which exceeds the continuous current rating of both components.

Q: Are there supply chain differences between these manufacturers?

A: The CDRH127C/ANP-151MC is manufactured by Sumida America Components Inc., while the B82477G4154M000 is manufactured by EPCOS - TDK Electronics. Both manufacturers maintain active production status for these parts. Inventory availability and lead times may differ based on regional distribution and market demand.

Q: What core construction differences exist between these inductors?

A: The CDRH127C/ANP-151MC uses standard ferrite core construction. The B82477G4154M000 uses drum core wirewound construction with ferrite material. Both achieve equivalent shielding and inductance performance through different physical designs. The wirewound construction in the substitute part may provide improved saturation characteristics.
