Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDRH74-150MC are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Matching Parameters:

• Inductance value: 15 µH
• Inductance tolerance: ±20%
• Shielding requirement: Shielded
• Mounting type: Surface Mount
• Operating temperature range compatibility
• Physical dimensions and height compatibility
• MSL rating: 1 (Unlimited)

Secondary Compatibility Parameters:

• Current rating must meet or exceed 1.47 A
• DC resistance must not exceed 81 mOhm Max
• Core material: Ferrite or equivalent shielded construction
• Package classification: Nonstandard

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Electrical Specifications): Parts that match all critical electrical parameters and physical dimensions with the main part.

Similar Substitutes (Enhanced Specifications): Parts that exceed the main part's electrical ratings while maintaining physical compatibility and core functional requirements.

Engineering Selection Recommendations

CDRH74NP-150MC-B (Direct Substitute - Recommended Primary Choice)

The CDRH74NP-150MC-B is the direct electrical and mechanical equivalent of the CDRH74-150MC. Both parts are manufactured by Sumida America Components Inc. within the same CDRH74 series. This substitute maintains identical inductance (15 µH), current rating (1.47 A), DC resistance (81 mOhm Max), operating temperature range (-40°C ~ 100°C), and physical dimensions (7.30 mm x 7.30 mm x 4.50 mm). The primary difference is product status: CDRH74NP-150MC-B is active production, whereas the main part is obsolete. CDRH74NP-150MC-B is ROHS3 compliant, providing regulatory advantage over the non-compliant main part. Packaging differs (Tape & Reel vs. Cut Tape), with significantly higher inventory availability (8142 Pcs vs. 746 Pcs).

P1167.153NLT (Similar Substitute - Enhanced Performance)

The P1167.153NLT manufactured by Pulse Electronics is a similar substitute with enhanced electrical specifications. It maintains the 15 µH inductance and ±20% tolerance. Current rating is increased to 1.7 A (exceeding the 1.47 A requirement), and DC resistance is reduced to 66 mOhm Max (lower than the 81 mOhm Max specification). Physical dimensions are slightly larger (7.54 mm x 7.54 mm) but height remains compatible at 4.50 mm. Operating temperature range extends to -40°C ~ 130°C, providing wider thermal operating margin. This part is ROHS3 compliant and active production with 4560 Pcs inventory availability.

DR74-150-R (Similar Substitute - Maximum Performance)

The DR74-150-R manufactured by Eaton - Electronics Division is a similar substitute with the highest electrical performance. It maintains 15 µH inductance and ±20% tolerance. Current rating reaches 2.11 A with saturation current of 2.48 A, significantly exceeding the 1.47 A requirement. DC resistance is 63.7 mOhm, the lowest among all substitutes. Physical dimensions are 7.60 mm x 7.60 mm with height of 4.35 mm (slightly lower than main part). Operating temperature range is -40°C ~ 125°C. This part is ROHS3 compliant, active production, with 1290 Pcs inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-150MC-B be used as a direct replacement for CDRH74-150MC?

A: Yes. CDRH74NP-150MC-B is a direct electrical and mechanical equivalent. Both parts share identical inductance (15 µH), current rating (1.47 A), DC resistance (81 mOhm Max), operating temperature range (-40°C ~ 100°C), and physical dimensions (7.30 mm x 7.30 mm x 4.50 mm). The substitute is active production with higher inventory availability and ROHS3 compliance.

Q: What are the differences between the three substitute options?

A: CDRH74NP-150MC-B is a direct equivalent with identical specifications. P1167.153NLT and DR74-150-R are similar substitutes with enhanced current ratings (1.7 A and 2.11 A respectively) and lower DC resistance values (66 mOhm and 63.7 mOhm respectively). All three maintain the 15 µH inductance requirement and are physically compatible with the main part.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The main part CDRH74-150MC is supplied in Cut Tape (CT) packaging. All three substitutes are supplied in Tape & Reel (TR) packaging. This difference affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do the substitute parts meet RoHS compliance requirements?

A: The main part CDRH74-150MC is RoHS non-compliant. All three substitutes (CDRH74NP-150MC-B, P1167.153NLT, and DR74-150-R) are ROHS3 compliant, providing regulatory advantage for new designs and applications with RoHS requirements.

Q: Can P1167.153NLT or DR74-150-R be used in applications designed for CDRH74-150MC?

A: Yes. Both P1167.153NLT and DR74-150-R maintain the 15 µH inductance and ±20% tolerance. Their enhanced current ratings and lower DC resistance values are compatible with applications designed for the lower-rated main part. Physical dimensions are slightly larger but height remains within acceptable limits. Operating temperature ranges are extended, providing additional margin.

Q: What is the inventory status for each substitute?

A: CDRH74NP-150MC-B has the highest availability with 8142 Pcs in stock. P1167.153NLT has 4560 Pcs available. DR74-150-R has 1290 Pcs available. The main part CDRH74-150MC has 746 Pcs in stock but is obsolete production.

Q: Are there differences in inductance test frequency between parts?

A: Yes. The main part CDRH74-150MC and CDRH74NP-150MC-B use 1 kHz test frequency. P1167.153NLT and DR74-150-R use 100 kHz test frequency. Both frequencies are standard industry practices and do not affect substitution compatibility for the specified 15 µH inductance value.

Q: What is the maximum operating temperature for each part?

A: CDRH74-150MC and CDRH74NP-150MC-B are rated to 100°C. P1167.153NLT extends to 130°C. DR74-150-R extends to 125°C. Applications requiring operation above 100°C should use P1167.153NLT or DR74-150-R.
