Engineering Selection Recommendations

The CDRH127/LDNP-561MC is the direct substitute for the obsolete CDRH127/LD-561MC. Selection of the substitute part is based on the following engineering factors:

Product Status: The main part CDRH127/LD-561MC carries obsolete status, making the active CDRH127/LDNP-561MC the appropriate replacement to ensure continued supply and design support.

Compliance & Certifications: The substitute part CDRH127/LDNP-561MC is ROHS3 compliant, whereas the main part is RoHS non-compliant. This compliance upgrade supports modern regulatory requirements and environmental standards.

Electrical & Mechanical Equivalence: All critical electrical parameters (inductance, current rating, DC resistance, shielding) and mechanical parameters (dimensions, mounting type, height) are identical between the main part and substitute, ensuring direct functional replacement without circuit redesign.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) packaging, which differs from the bulk packaging of the main part. This packaging format is standard for automated assembly processes and high-volume production environments.

Core Material: The substitute part specifies ferrite core material, providing documented material composition for quality assurance and traceability purposes.

Frequently Asked Questions (FAQ)

Q: Can CDRH127/LDNP-561MC be used as a direct replacement for CDRH127/LD-561MC in existing designs?

A: Yes. The CDRH127/LDNP-561MC is a direct electrical and mechanical equivalent. All specified inductance, current rating, DC resistance, shielding, dimensional, and environmental parameters are identical. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), packaging format (bulk vs. Tape & Reel), and documented core material (unspecified vs. ferrite). Electrical and mechanical performance are equivalent.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly. If your production process uses manual placement or bulk component handling, packaging format compatibility should be verified with your assembly partner or manufacturing process documentation.

Q: Does the ROHS3 compliance of the substitute part affect circuit performance?

A: No. ROHS3 compliance is a regulatory and environmental certification that does not alter electrical performance or functional characteristics. The substitute part maintains identical electrical specifications to the main part.

Q: Are there any temperature or frequency limitations when substituting this part?

A: No. Both parts operate across the identical temperature range (-40°C ~ 100°C) and are tested at the same inductance frequency (1 kHz). No operational limitations apply to the substitution.

Q: What is the moisture sensitivity level for this inductor?

A: Both the main part and substitute are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply.
