Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDRH62NP-271MC is determined by the following critical parameters:

Inductance Value: Both the main part and substitute must maintain 270 µH inductance at 1 kHz test frequency with ±20% tolerance.

Current Rating: The substitute must support the application's current requirements. The CDRH62NP-271MC is rated for 200 mA; substitutes with equal or higher current ratings are acceptable.

DC Resistance: The substitute's DCR must not exceed the maximum allowable value for the application circuit. Lower DCR values reduce power dissipation and heat generation.

Physical Dimensions: Surface mount package dimensions must match or be compatible with existing PCB layouts. The CDRH62NP-271MC uses a nonstandard 6.60mm x 6.20mm x 3.00mm footprint.

Mounting Type: Both parts must be surface mount compatible.

Compliance Requirements: RoHS3 compliance and MSL 1 rating are mandatory for supply chain and manufacturing process compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-274M from API Delevan Inc. is an active product substitute for the obsolete CDRH62NP-271MC. Both components share identical inductance values, tolerance specifications, physical dimensions, and mounting compatibility.

The SPD62R-274M provides superior electrical performance characteristics: 290 mA current rating exceeds the original 200 mA specification, and 3 Ohm maximum DCR is lower than the original 4.89 Ohm specification, resulting in reduced power dissipation. The substitute operates across an extended temperature range of -55°C to 125°C compared to the original -40°C to 100°C range.

Both parts maintain RoHS3 compliance and MSL 1 moisture sensitivity ratings, ensuring compatibility with current manufacturing and supply chain requirements. The SPD62R-274M is available in standard Tape & Reel packaging, supporting automated assembly processes.

The primary design consideration is the shielding difference: the SPD62R-274M features shielding with ferrite drum core construction, while the CDRH62NP-271MC is unshielded. Shielded construction reduces electromagnetic interference emission and susceptibility, which may alter circuit behavior in sensitive applications. Circuit validation is required to confirm functional equivalence in the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-274M directly replace the CDRH62NP-271MC in existing designs?

A: Physical footprint and electrical specifications are compatible. However, the shielded construction of the SPD62R-274M differs from the unshielded CDRH62NP-271MC. Applications sensitive to electromagnetic field characteristics require circuit validation before implementation.

Q: What is the significance of the lower DC resistance in the SPD62R-274M?

A: The SPD62R-274M DCR of 3 Ohm maximum is lower than the CDRH62NP-271MC DCR of 4.89 Ohm maximum. Lower DCR reduces resistive power loss (I²R losses), resulting in lower heat generation and improved efficiency. This is a beneficial characteristic for most applications.

Q: Does the higher current rating of the SPD62R-274M affect compatibility?

A: The SPD62R-274M 290 mA current rating exceeds the CDRH62NP-271MC 200 mA rating. Higher current ratings indicate greater saturation margin and thermal capability. This provides additional design margin and does not create compatibility issues for applications operating at or below 200 mA.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CDRH62NP-271MC and SPD62R-274M are RoHS3 compliant with MSL 1 moisture sensitivity ratings, meeting current regulatory and manufacturing requirements.

Q: What packaging formats are available?

A: The CDRH62NP-271MC uses nonstandard packaging. The SPD62R-274M is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly processes and provides improved supply chain availability.

Q: How do the operating temperature ranges compare?

A: The CDRH62NP-271MC operates from -40°C to 100°C. The SPD62R-274M operates from -55°C to 125°C, providing extended low-temperature and high-temperature capability. Applications operating within the original temperature range are fully compatible.
