Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRH124NP-101MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 100 µH (fixed requirement)
• Inductance tolerance: ±20% (fixed requirement)
• Current rating: minimum 1.2 A
• DC resistance: maximum 308mOhm
• Mounting type: Surface Mount (fixed requirement)
• Inductance test frequency: 100 kHz (fixed requirement)
• RoHS3 compliance (fixed requirement)
• Moisture sensitivity level: 1 (Unlimited) (fixed requirement)

Secondary Compatibility Factors:

• Operating temperature range: minimum -40°C to 100°C
• Shielding configuration: Shielded (preferred for EMI-sensitive applications)
• Package dimensions: Nonstandard (physical fit verification required)
• Packaging format: Tape & Reel (TR)

Substitute parts are classified as direct equivalents when all primary matching criteria are met. Parts meeting primary criteria with variations in secondary factors are classified as compatible alternatives suitable for applications where the secondary parameter variation does not impact circuit performance.

Parameter Comparison

Engineering Selection Recommendations

P1168.104NLT (Pulse Electronics)

This part meets all primary matching criteria with equivalent current rating and lower DC resistance (270mOhm vs. 308mOhm maximum). The shielded wirewound construction provides EMI performance equivalent to the main part. Extended operating temperature range to 130°C provides additional thermal margin. Self-resonant frequency of 6MHz and saturation current of 1.2A are specified. RoHS3 compliance and MSL 1 rating match the main part. This part is suitable as a direct equivalent for applications requiring shielded performance within the specified temperature range.

SRR1240-101M (Bourns Inc.)

This part satisfies all primary matching criteria with slightly elevated current rating (1.25A vs. 1.2A) and DC resistance within specification (300mOhm vs. 308mOhm maximum). The ferrite drum core wirewound construction provides shielded performance. Operating temperature range extends to 125°C. Q factor of 14 at 796kHz and self-resonant frequency of 8MHz are specified. RoHS3 compliance and MSL 1 rating are confirmed. This part is suitable as a direct equivalent for applications where the elevated current rating and extended temperature range provide design benefits.

DRA124-101-R (Eaton - Electronics Division)

This part meets all primary matching criteria with current rating of 1.199A and DC resistance of 296mOhm, both within specification. The shielded wirewound construction matches the main part's EMI performance. Operating temperature range extends to 165°C, providing significant thermal margin. AEC-Q200 automotive qualification is specified. RoHS3 compliance and MSL 1 rating are confirmed. This part is suitable as a direct equivalent for applications requiring extended temperature operation and automotive-grade reliability.

UP2B-101-R (Eaton - Electronics Division)

This part meets all primary matching criteria with equivalent current rating (1.2A) and lower DC resistance (270.7mOhm vs. 308mOhm maximum). However, this part features unshielded construction, which differs from the main part's shielded design. The ferrite drum core wirewound type is specified. Operating temperature range is limited to -40°C to 85°C, which is below the main part's 100°C maximum. This part is suitable as a compatible alternative only for applications where EMI shielding is not required and operating temperature does not exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can P1168.104NLT be used as a direct replacement for CDRH124NP-101MC?

A: Yes. P1168.104NLT meets all primary matching criteria: 100 µH inductance with ±20% tolerance, 1.2 A current rating, DC resistance of 270mOhm (within the 308mOhm maximum), shielded construction, surface mount configuration, 100 kHz test frequency, RoHS3 compliance, and MSL 1 rating. The lower DC resistance provides improved efficiency. Extended operating temperature to 130°C provides additional thermal margin.

Q: What is the key difference between SRR1240-101M and the main part CDRH124NP-101MC?

A: Both parts meet all primary matching criteria. SRR1240-101M features a ferrite drum core wirewound construction versus the main part's ferrite core design. Current rating is slightly higher (1.25A vs. 1.2A), and DC resistance is 300mOhm versus 308mOhm maximum. Operating temperature extends to 125°C. These differences represent performance enhancements suitable for applications requiring higher current margin or extended thermal operation.

Q: Why is UP2B-101-R classified as a compatible alternative rather than a direct equivalent?

A: UP2B-101-R features unshielded construction, whereas CDRH124NP-101MC is shielded. This difference is significant for applications requiring EMI suppression or operating in electromagnetically noisy environments. Additionally, the operating temperature range of UP2B-101-R is limited to -40°C to 85°C, below the main part's 100°C maximum. UP2B-101-R is suitable only for applications where shielding is not required and operating temperature remains below 85°C.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging format, matching the main part's packaging specification.

Q: Do all substitute parts comply with RoHS3 and MSL 1 requirements?

A: Yes. All substitute parts are RoHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity level), matching the main part's environmental compliance specifications.

Q: What is the significance of DC resistance differences among the substitute parts?

A: DC resistance directly impacts power dissipation and thermal performance. Lower DC resistance reduces I²R losses. P1168.104NLT and UP2B-101-R both feature 270-270.7mOhm (approximately 12% lower than the main part's 308mOhm maximum), resulting in reduced heat generation. SRR1240-101M at 300mOhm and DRA124-101-R at 296mOhm provide intermediate performance. Selection should consider circuit current levels and thermal budget requirements.

Q: Can DRA124-101-R be used in automotive applications?

A: Yes. DRA124-101-R carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The extended operating temperature range to 165°C supports automotive thermal requirements. Other substitute parts do not carry automotive qualification ratings.

Q: What physical dimension considerations apply when selecting a substitute?

A: All parts are classified as Nonstandard package type. Physical dimensions vary slightly: CDRH124NP-101MC is 12.00mm × 12.00mm × 4.50mm; P1168.104NLT is 12.24mm × 12.24mm × 4.50mm; SRR1240-101M is 12.50mm × 12.50mm × 4.50mm; DRA124-101-R is 12.50mm × 12.50mm × 4.50mm; UP2B-101-R is 13.97mm × 10.41mm × 6.00mm. PCB layout and clearance verification is required before substitution.
