Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDRH74-102MC are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 1 mH (±20% tolerance)
• Current rating: minimum 180 mA
• DC resistance: within acceptable operating limits
• Shielding: shielded construction required
• Mounting: surface mount technology
• Package footprint: nonstandard 7.30mm class dimensions
• Operating temperature: minimum -40°C to 100°C range

Substitution Categories:

Direct Equivalent: Parts maintaining identical electrical specifications and packaging compatibility with the main part.

Similar Equivalent: Parts meeting core electrical requirements (inductance, current rating, shielding) with minor variations in DCR, current saturation characteristics, or temperature range that do not compromise circuit functionality within the specified operating envelope.

Engineering Selection Recommendations

CDRH74NP-102MC-B (Direct Equivalent - Recommended Primary Substitute)

The CDRH74NP-102MC-B is the preferred direct substitute for the obsolete CDRH74-102MC. Both parts are manufactured by Sumida America Components Inc. within the same CDRH74 series and maintain identical electrical specifications: 1 mH inductance, 180 mA current rating, 6 Ohm maximum DC resistance, and matching physical dimensions (7.30mm × 7.30mm × 4.50mm). The CDRH74NP-102MC-B is currently in active production status with 57,190 units in stock. The primary distinction is RoHS3 compliance of the substitute versus non-compliance of the original part. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly processes.

DR74-102-R (Similar Equivalent - Extended Performance)

The DR74-102-R from Eaton Electronics Division qualifies as a similar equivalent with enhanced electrical performance characteristics. This part maintains the 1 mH inductance specification and ferrite core construction but offers improved current handling at 270 mA (versus 180 mA) with lower DC resistance of 3.89 Ohm. The extended operating temperature range (-40°C to 125°C) provides additional thermal margin. Physical dimensions are slightly larger (7.60mm × 7.60mm × 4.35mm), requiring verification of PCB layout compatibility. This substitute is suitable for applications requiring higher current capacity or lower resistive losses. RoHS3 compliance and active product status are confirmed.

P1167.105NLT (Similar Equivalent - Compact Alternative)

The P1167.105NLT from Pulse Electronics represents an alternative substitute meeting core electrical requirements with minor parameter variations. Inductance and tolerance remain at 1 mH ±20%. Current rating of 190 mA exceeds the original 180 mA specification. DC resistance of 4.93 Ohm is lower than the 6 Ohm maximum of the original part. Physical footprint (7.54mm × 7.54mm × 4.50mm) is intermediate between the original and DR74-102-R. Operating temperature range extends to 130°C. This part is supplied in Tape & Reel packaging with RoHS3 compliance and active production status. Frequency-dependent characteristics (self-resonant frequency 1.8 MHz) are documented.

Compliance and Availability Considerations

All three substitute parts carry RoHS3 compliance certification, addressing regulatory requirements that the original obsolete part does not meet. Inventory availability is confirmed for all substitutes: CDRH74NP-102MC-B (57,190 units), DR74-102-R (2,000 units), and P1167.105NLT (2,900 units). Selection should prioritize CDRH74NP-102MC-B for direct replacement in existing designs, with DR74-102-R or P1167.105NLT considered for new designs where enhanced performance or alternative sourcing is beneficial.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-102MC-B be used as a direct replacement for CDRH74-102MC without circuit modification?

A: Yes. The CDRH74NP-102MC-B maintains identical electrical specifications (1 mH, 180 mA, 6 Ohm DCR) and physical dimensions (7.30mm × 7.30mm × 4.50mm). No circuit modifications are required. The primary difference is RoHS3 compliance of the substitute.

Q: What are the key differences between CDRH74NP-102MC-B and DR74-102-R?

A: Both parts maintain 1 mH inductance and ferrite core construction. DR74-102-R offers higher current rating (270 mA vs. 180 mA), lower DC resistance (3.89 Ohm vs. 6 Ohm), extended temperature range (-40°C to 125°C vs. -40°C to 100°C), and slightly larger footprint (7.60mm vs. 7.30mm). DR74-102-R is suitable for applications requiring higher current capacity or lower power dissipation.

Q: Is P1167.105NLT compatible with the original CDRH74-102MC footprint?

A: P1167.105NLT dimensions (7.54mm × 7.54mm × 4.50mm) are slightly larger than the original (7.30mm × 7.30mm × 4.50mm). PCB layout compatibility must be verified before substitution. The height remains identical at 4.50mm.

Q: Which substitute part should be selected for new product designs?

A: CDRH74NP-102MC-B is recommended for designs requiring direct compatibility with existing specifications. For new designs, DR74-102-R or P1167.105NLT may be preferred if their enhanced performance characteristics (higher current rating, lower DCR, extended temperature range) provide circuit benefits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CDRH74NP-102MC-B, DR74-102-R, and P1167.105NLT all carry RoHS3 compliance certification. The original CDRH74-102MC is RoHS non-compliant.

Q: What packaging formats are available for these substitute parts?

A: CDRH74NP-102MC-B and P1167.105NLT are supplied in Tape & Reel (TR) format. DR74-102-R is available in Cut Tape (CT) and Digi-Reel® format. Packaging selection should align with assembly process requirements.

Q: Can these inductors be used interchangeably in high-frequency applications?

A: Inductance value and tolerance are maintained across all substitutes. However, frequency-dependent characteristics vary. P1167.105NLT specifies self-resonant frequency at 1.8 MHz. For applications sensitive to frequency response, component-level testing or simulation is recommended to confirm performance equivalence.

Q: What is the current saturation rating for each substitute?

A: CDRH74-102MC and CDRH74NP-102MC-B do not specify saturation current. DR74-102-R specifies 310 mA saturation current. P1167.105NLT specifies 190 mA saturation current (equal to rated current). Applications requiring saturation margin should reference these specifications.
