Substitute Part Grouping Explanation

Substitute parts for the CDRH62B-331MC are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Inductance: 330 µH (exact match required)
• Current Rating: 190 mA (minimum requirement)
• DC Resistance: ≤4.94 Ohm Max (equal or lower acceptable)
• Shielding: Shielded (required)
• Mounting Type: Surface Mount (required)
• Operating Temperature Range: Must encompass -40°C to 100°C minimum
• Tolerance: ±20% (standard for this category)

Secondary Considerations:

• Physical dimensions must accommodate PCB layout constraints (6.60mm × 6.20mm footprint, 3.00mm max height)
• Packaging format (Tape & Reel preferred for production continuity)
• Product status (Active status preferred for long-term availability)
• Compliance certifications (RoHS3 compliance preferred for new designs)

Engineering Selection Recommendations

CDRH62BNP-331MC-B (Sumida America Components Inc.)

This part is the primary substitute for the obsolete CDRH62B-331MC. It maintains identical electrical specifications (330 µH inductance, 190 mA current rating, 4.94 Ohm max DCR) and mechanical dimensions (6.60mm × 6.20mm × 3.00mm). The CDRH62BNP-331MC-B is classified as Active product status, ensuring long-term availability. It is supplied in Tape & Reel packaging, suitable for automated assembly processes. The part achieves ROHS3 compliance, meeting modern regulatory requirements. This substitute provides direct compatibility with existing PCB layouts and assembly procedures.

PF0601.334NLT (Pulse Electronics)

This part qualifies as a secondary substitute based on matching electrical parameters and mechanical compatibility. It provides 330 µH inductance at 190 mA current rating with a lower DC resistance of 3.3 Ohm Max, representing an improvement over the original specification. The PF0601.334NLT operates across an extended temperature range (-40°C to 130°C), exceeding the original requirement. Physical dimensions (6.90mm × 6.50mm × 3.00mm) are slightly larger but remain compatible with standard PCB layouts. The part is Active status and ROHS3 compliant. The wirewound construction type differs from the ferrite core of the original part. Selection of this substitute requires verification that the increased footprint dimensions and alternative core material do not conflict with circuit design constraints.

Frequently Asked Questions (FAQ)

Q: Can CDRH62BNP-331MC-B be used as a direct replacement for CDRH62B-331MC?

A: Yes. The CDRH62BNP-331MC-B maintains identical inductance (330 µH), current rating (190 mA), DC resistance (4.94 Ohm max), operating temperature range (-40°C to 100°C), and physical dimensions (6.60mm × 6.20mm × 3.00mm). The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit redesign is required.

Q: What are the key differences between CDRH62BNP-331MC-B and PF0601.334NLT?

A: Both parts meet the core electrical requirements (330 µH, 190 mA, shielded, surface mount). The CDRH62BNP-331MC-B uses ferrite core material with 4.94 Ohm max DCR, while PF0601.334NLT uses wirewound construction with 3.3 Ohm max DCR. Physical dimensions differ slightly (6.60mm × 6.20mm vs. 6.90mm × 6.50mm). The PF0601.334NLT operates to 130°C versus 100°C for the Sumida part. Both are Active status and ROHS3 compliant.

Q: Why is the CDRH62B-331MC classified as obsolete?

A: The CDRH62B-331MC is marked obsolete by the manufacturer. The CDRH62BNP-331MC-B represents the active production equivalent with identical specifications and improved compliance status.

Q: Are there packaging differences between the substitute parts?

A: The CDRH62BNP-331MC-B is supplied in Tape & Reel (TR) packaging, optimized for automated assembly. The PF0601.334NLT packaging format is not specified in the provided data. Tape & Reel packaging is standard for high-volume production environments.

Q: Can PF0601.334NLT be used in applications requiring the exact ferrite core material?

A: No. The PF0601.334NLT uses wirewound construction, which differs from the ferrite core of the original CDRH62B-331MC. If ferrite core material is a design requirement, the CDRH62BNP-331MC-B is the appropriate substitute.

Q: What is the impact of lower DC resistance in PF0601.334NLT?

A: The PF0601.334NLT provides 3.3 Ohm max DCR compared to 4.94 Ohm max in the original part. Lower DC resistance reduces power dissipation and heat generation in the inductor. This represents an electrical improvement but requires verification that the alternative core material and construction type are compatible with the circuit design.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CDRH62BNP-331MC-B and PF0601.334NLT are ROHS3 compliant. The original CDRH62B-331MC is RoHS non-compliant. For new designs or applications requiring RoHS compliance, either substitute part is acceptable.
