Substitute Part Grouping Explanation

Substitute parts for the CDRH127-271MC are identified based on strict electrical and mechanical parameter matching within the CDRH127 series. The substitution criteria are:

Primary Matching Parameters:

  • Inductance value: 270 µH
  • Inductance tolerance: ±20%
  • Current rating: 1.06 A
  • DC resistance: 560mOhm Max
  • Shielding type: Shielded
  • Mounting type: Surface Mount
  • Physical dimensions: 12.00mm x 12.00mm x 8.00mm (Max)
  • Operating temperature range: -40°C ~ 100°C
  • Test frequency: 1 kHz

The CDRH127NP-271MC qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status and packaging configuration, not functional performance parameters.

Engineering Selection Recommendations

CDRH127NP-271MC is the direct substitute for CDRH127-271MC based on the following engineering criteria:

  1. Electrical Equivalence: All electrical parameters are identical, including inductance value, tolerance, current rating, and DC resistance specifications.

  2. Mechanical Compatibility: Physical dimensions and mounting characteristics are identical, ensuring direct PCB footprint compatibility without layout modifications.

  3. Product Status: CDRH127NP-271MC maintains active product status with current manufacturing availability, addressing the obsolescence of the original CDRH127-271MC.

  4. Compliance Improvement: CDRH127NP-271MC is ROHS3 compliant, whereas the original part is RoHS non-compliant. This provides enhanced regulatory alignment for new designs and procurement cycles.

  5. Packaging Configuration: CDRH127NP-271MC is supplied in Tape & Reel (TR) format, which is standard for automated assembly operations, compared to bulk packaging of the original part.

Selection of CDRH127NP-271MC requires no circuit redesign, thermal analysis revision, or performance re-qualification based on provided electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can CDRH127NP-271MC be used as a direct replacement for CDRH127-271MC in existing designs?

A: Yes. Both parts share identical inductance (270 µH), current rating (1.06 A), DC resistance (560mOhm Max), physical dimensions (12.00mm x 12.00mm x 8.00mm), and operating temperature range (-40°C ~ 100°C). No circuit modifications are required.

Q: What is the difference between CDRH127-271MC and CDRH127NP-271MC?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of CDRH127NP-271MC affect compatibility?

A: No. Tape & Reel packaging is a supply format that does not affect component electrical performance or PCB mounting compatibility. The component itself is identical.

Q: Is RoHS3 compliance of CDRH127NP-271MC a requirement for substitution?

A: RoHS3 compliance is an advantage for regulatory alignment and future procurement cycles. However, substitution is based on electrical and mechanical parameter equivalence. Compliance status should be evaluated against specific application and regional requirements.

Q: Are there any thermal or frequency performance differences between these parts?

A: No thermal or frequency performance parameters are provided in the component specifications. Both parts are tested at 1 kHz and operate within the same temperature range (-40°C ~ 100°C). Substitution is valid based on provided specifications.

Q: What is the inventory status for CDRH127NP-271MC?

A: CDRH127NP-271MC has 838 pieces in new original stock. Inventory levels should be verified with the supplier for current availability and lead time requirements.
