Substitute Part Grouping Explanation

Substitute parts for the CDRH62B-271MC are identified based on strict electrical and mechanical parameter matching within acceptable tolerances for this product category. The following criteria determine substitution eligibility:

Primary Matching Criteria:

• Inductance value: 270 µH (±20% tolerance band)
• Current rating: 220 mA minimum
• DC resistance: Maximum 4.38 Ohm (or lower)
• Shielding: Shielded construction required
• Mounting type: Surface Mount
• Physical dimensions: Compatible with 6.60 x 6.20 mm footprint and 3.00 mm maximum height
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Considerations:

• Operating temperature range must encompass or exceed the original specification
• RoHS and REACH compliance status
• Product status and availability

Substitute parts are grouped into direct equivalents where all electrical parameters match within specification, and the physical package accommodates the original mounting footprint.

Parameter Comparison

Engineering Selection Recommendations

CDRH62BNP-271MC-B (Sumida America Components Inc.)

This part is the direct equivalent to the CDRH62B-271MC within the same manufacturer series. Electrical parameters are identical: 270 µH inductance, 220 mA current rating, and 4.38 Ohm maximum DC resistance. Physical dimensions and height are identical. The CDRH62BNP-271MC-B is currently in active production status with 884 units in stock, providing supply continuity. The operating temperature range extends to -40°C, providing improved low-temperature performance. This part achieves ROHS3 compliance, whereas the original part is non-compliant. Packaging is specified as Tape & Reel (TR), supporting automated assembly processes.

PF0601.274NLT (Pulse Electronics)

This part meets all critical electrical substitution criteria: 270 µH inductance, 220 mA current rating, and shielded surface mount construction. The DC resistance is 3.0 Ohm maximum, which is lower than the original 4.38 Ohm specification, providing improved efficiency characteristics. Physical dimensions are 6.90 x 6.50 mm, representing a 0.30 mm increase in length and 0.30 mm increase in width compared to the original footprint; height remains at 3.00 mm maximum. The operating temperature range extends to -40°C to 130°C, exceeding the original specification. This part is wirewound construction with a self-resonant frequency of 5.8 MHz and is tested at 100 kHz. ROHS3 compliance is achieved. Current inventory is 1060 units.

Both substitute parts satisfy the core electrical requirements and physical constraints. Selection between them depends on specific application requirements regarding DC resistance performance, physical footprint tolerance, and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can CDRH62BNP-271MC-B be used as a direct replacement for CDRH62B-271MC?

A: Yes. Both parts are from the Sumida CDRH62 series with identical electrical specifications: 270 µH inductance, 220 mA current rating, 4.38 Ohm maximum DC resistance, and shielded ferrite core construction. Physical dimensions and mounting footprint are identical. The primary difference is product status (active vs. obsolete) and RoHS compliance level.

Q: What are the physical footprint differences between the substitute parts?

A: The CDRH62BNP-271MC-B maintains the original 6.60 x 6.20 mm footprint. The PF0601.274NLT has dimensions of 6.90 x 6.50 mm, representing a 0.30 mm increase in both length and width. All three parts share the same 3.00 mm maximum height. Verify PCB layout clearances before selecting the Pulse Electronics part.

Q: How do DC resistance values affect substitution?

A: The CDRH62B-271MC and CDRH62BNP-271MC-B both specify 4.38 Ohm maximum DC resistance. The PF0601.274NLT specifies 3.0 Ohm maximum, which is lower. Lower DC resistance reduces power dissipation and heat generation in the inductor. This is generally beneficial but may affect circuit tuning or impedance matching if the original design relied on the higher resistance value.

Q: Are there temperature range considerations for substitution?

A: The original CDRH62B-271MC operates from -30°C to 100°C. The CDRH62BNP-271MC-B extends the lower limit to -40°C. The PF0601.274NLT extends both limits to -40°C to 130°C. If the application requires operation below -30°C or above 100°C, the substitute parts provide extended capability. Verify that other circuit components support the extended temperature range.

Q: What is the significance of the inductance test frequency difference?

A: The CDRH62B-271MC and CDRH62BNP-271MC-B are tested at 1 kHz, while the PF0601.274NLT is tested at 100 kHz. Inductance values can vary with frequency due to core material properties. The 270 µH specification applies at the stated test frequency. For applications operating at frequencies significantly different from the test frequency, verify that inductance variation remains acceptable.

Q: Does RoHS compliance affect functional substitution?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional parameter. The CDRH62B-271MC is RoHS non-compliant. Both substitute parts achieve ROHS3 compliance. If the application or end-market requires RoHS compliance, the substitute parts satisfy this requirement. Functional performance is not affected by RoHS status.

Q: Can the PF0601.274NLT be used in space-constrained applications?

A: The PF0601.274NLT has a slightly larger footprint (6.90 x 6.50 mm vs. 6.60 x 6.20 mm). If the PCB layout has tight spacing constraints, verify that the additional 0.30 mm in length and width can be accommodated. The height remains identical at 3.00 mm maximum.
