• Inductance Tolerance: -15%, +20%
• Current Rating: 850 mA
• DC Resistance: 400mOhm Max
• Shielding: Shielded
• Frequency - Self Resonant: 5.55 MHz

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Surface Mount
• Size / Dimension: 12.60mm L x 11.60mm W
• Height - Seated (Max): 5.90mm

Series Compatibility:

• Series: CDR125

The CDR125NP-151MC qualifies as a direct equivalent substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between the main part and substitute relates to product status classification and packaging configuration, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

CDR125NP-151MC is the qualified equivalent substitute for CDR125-151MC based on the following engineering criteria:

Product Status: The CDR125NP-151MC carries Active product status, ensuring continued manufacturer support, availability, and supply chain stability. The original CDR125-151MC is classified as Obsolete, creating long-term sourcing risk.

Compliance Certifications: The CDR125NP-151MC is ROHS3 Compliant, meeting current regulatory requirements for electronic component manufacturing and distribution. The CDR125-151MC is RoHS non-compliant, which may restrict use in applications subject to RoHS directives.

Packaging Configuration: The CDR125NP-151MC is supplied in Tape & Reel (TR) packaging, standard for automated assembly processes. The original part is supplied in bulk packaging. This difference does not affect electrical or mechanical performance but impacts manufacturing workflow compatibility.

Operating Temperature Range: The CDR125NP-151MC supports -40°C ~ 100°C operation, providing extended temperature coverage compared to the original part's -25°C ~ 70°C range. This expanded range offers design flexibility for applications requiring broader thermal performance.

Electrical and Mechanical Equivalence: All critical electrical parameters (inductance, current rating, DC resistance, shielding, self-resonant frequency) and mechanical parameters (mounting type, physical dimensions, height) are identical between both parts, confirming functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CDR125NP-151MC be used as a direct replacement for CDR125-151MC in existing designs?

A: Yes. The CDR125NP-151MC is electrically and mechanically equivalent to CDR125-151MC. All critical specifications including inductance (150 µH), current rating (850 mA), DC resistance (400mOhm Max), shielding, physical dimensions (12.60 x 11.60 x 5.90 mm), and mounting type (Surface Mount) are identical. The substitute part is suitable for direct PCB layout and schematic replacement without design modification.

Q: What is the primary reason to transition from CDR125-151MC to CDR125NP-151MC?

A: The CDR125-151MC is classified as Obsolete product status, indicating discontinued manufacturing and declining inventory availability. The CDR125NP-151MC is Active status, ensuring reliable long-term supply, manufacturer technical support, and compliance with current regulatory standards. Transitioning to the active equivalent part mitigates supply chain risk and ensures design sustainability.

Q: Are there packaging differences between these parts, and do they affect circuit performance?

A: Yes, packaging differs. CDR125-151MC is supplied in bulk packaging, while CDR125NP-151MC is supplied in Tape & Reel (TR) format. This difference affects manufacturing logistics and automated assembly compatibility but does not impact electrical performance, inductance value, current rating, or any functional characteristic. Component performance is identical regardless of packaging format.

Q: Does the expanded operating temperature range of CDR125NP-151MC affect compatibility?

A: No. The CDR125NP-151MC supports -40°C ~ 100°C operation, compared to CDR125-151MC's -25°C ~ 70°C range. The substitute part's broader temperature specification is a superset of the original part's range, ensuring full compatibility. Applications operating within the original temperature range will function identically with the substitute part.

Q: What compliance advantages does CDR125NP-151MC provide?

A: The CDR125NP-151MC is ROHS3 Compliant, meeting current European Union Restriction of Hazardous Substances directives. The original CDR125-151MC is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the substitute part satisfies these regulatory obligations.

Q: Are the electrical characteristics identical between both parts?

A: Yes. Inductance (150 µH), inductance tolerance (-15%, +20%), current rating (850 mA), DC resistance (400mOhm Max), shielding (Shielded), self-resonant frequency (5.55 MHz), and inductance test frequency (1 kHz) are identical. Both parts are manufactured by Sumida America Components Inc. within the CDR125 series and deliver equivalent electrical performance.
