Engineering Selection Recommendations

B82477G4683M000 as Substitute for CDRH127C/ANP-680MC:

The B82477G4683M000 qualifies as an electrical equivalent with the following considerations:

Advantages:

• Current rating of 2.1 A exceeds the 1.8 A requirement, providing operational margin
• Saturation current specification (2.45 A) is provided, enabling precise circuit analysis
• Extended operating temperature range (-55°C to 125°C) covers the original specification and provides additional low-temperature capability
• Both parts maintain Active product status and RoHS3 compliance
• Identical inductance value and tolerance (68 µH ±20%)
• Identical height (8.00 mm seated maximum)
• Identical MSL rating (1 - Unlimited)

Limitations:

• DC resistance maximum of 120 mOhm exceeds the original specification of 88.2 mOhm by 31.8 mOhm. This increase results in higher power dissipation and heat generation in the inductor. Circuit thermal analysis is required to confirm acceptability in the target application.
• Package footprint dimensions are 12.80 × 12.80 mm, compared to 12.50 × 12.50 mm for the original part. PCB layout verification is necessary to confirm fit within the allocated space.

Selection Criteria: The B82477G4683M000 is suitable for substitution when the application can tolerate the increased DC resistance and the PCB layout accommodates the slightly larger footprint dimensions. Both parts are manufactured by established suppliers with equivalent regulatory compliance and active product status.

Frequently Asked Questions (FAQ)

Q: Can the B82477G4683M000 be used as a direct replacement for the CDRH127C/ANP-680MC?

A: The B82477G4683M000 is electrically compatible for inductance and current rating. However, two factors require evaluation: (1) the DC resistance is 31.8 mOhm higher, which increases power dissipation; (2) the footprint is 0.30 mm larger in length and width. PCB layout and thermal analysis must confirm acceptability before substitution.

Q: What is the impact of the higher DC resistance in the B82477G4683M000?

A: The B82477G4683M000 has a maximum DC resistance of 120 mOhm compared to 88.2 mOhm in the original part. At the rated current of 1.8 A, this results in additional power dissipation of approximately 57.6 mW (calculated as I²R difference). The circuit design must accommodate this additional heat generation without exceeding component or board temperature limits.

Q: Are the package dimensions compatible?

A: The B82477G4683M000 measures 12.80 × 12.80 mm compared to 12.50 × 12.50 mm for the CDRH127C/ANP-680MC. The 0.30 mm increase in each dimension must be verified against PCB layout constraints and clearance requirements. The seated height of 8.00 mm is identical for both parts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CDRH127C/ANP-680MC and B82477G4683M000 are RoHS3 compliant, carry MSL rating 1 (Unlimited), and maintain Active product status. Both are packaged in Tape & Reel format suitable for automated assembly.

Q: What is the difference in core construction between these parts?

A: The CDRH127C/ANP-680MC uses a standard ferrite core construction. The B82477G4683M000 uses a drum core wirewound construction with ferrite material. Both are shielded and designed for surface mount applications. The different construction methods account for the variations in DC resistance and saturation current specifications.

Q: Is the extended temperature range of the B82477G4683M000 beneficial?

A: The B82477G4683M000 operates from -55°C to 125°C, compared to -40°C to 125°C for the original part. The extended low-temperature capability (-55°C versus -40°C) provides additional margin for applications requiring operation in cold environments. The upper temperature limit of 125°C is identical for both parts.

Q: What inventory considerations apply to these parts?

A: The CDRH127C/ANP-680MC has 854 pieces in stock, while the B82477G4683M000 has 1244 pieces available. The substitute part offers greater inventory availability, which may support supply chain continuity and reduce lead times.
