CDRH74-120MC Equivalent & Substitute Parts

Part Overview

The CDRH74-120MC is a 12 µH shielded inductor manufactured by Sumida America Components Inc., rated for 1.71 A with a maximum DC resistance of 58 mOhm. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design support and procurement continuity. The part features a ferrite core, surface mount configuration, and nonstandard package dimensions of 7.30mm × 7.30mm × 4.50mm (seated height). Due to its obsolete status, direct replacements and functionally equivalent alternatives are required for system maintenance and new production applications.

Substitute Part Grouping Explanation

Substitute parts for the CDRH74-120MC are classified based on strict electrical and mechanical parameter alignment:

Direct Manufacturer Substitute (Same Manufacturer): The CDRH74NP-120MC-B is a direct equivalent from Sumida America Components Inc. This part maintains identical electrical specifications: 12 µH inductance, 1.71 A current rating, 58 mOhm maximum DC resistance, shielded ferrite core construction, and identical physical dimensions. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). This part is RoHS3 compliant, whereas the original is RoHS non-compliant.

Cross-Manufacturer Substitute (Functionally Equivalent): The P1167.123NLT from Pulse Electronics is classified as a similar substitute based on the following parameter alignment:

• Inductance: 12 µH (exact match)
• Current Rating: 1.9 A (exceeds minimum 1.71 A requirement)
• DC Resistance: 57 mOhm Max (within acceptable tolerance, 1 mOhm lower than original)
• Shielding: Shielded (meets requirement)
• Mounting Type: Surface Mount (compatible)
• Operating Temperature: -40°C ~ 130°C (exceeds original -40°C ~ 100°C range)
• Tolerance: ±20% (matches original)

Differences in the P1167.123NLT include wirewound construction type, slightly larger physical dimensions (7.54mm × 7.54mm), and different inductance test frequency (100 kHz versus 1 kHz). These differences do not preclude substitution when circuit design accommodates the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The CDRH74NP-120MC-B is the recommended substitute when component availability and form factor are primary considerations. This part is manufactured by the original equipment supplier, maintains identical electrical and mechanical specifications, and is currently in active production status. The transition from RoHS non-compliant to RoHS3 compliant status aligns with current regulatory requirements. Packaging format change from bulk to Tape & Reel (TR) may require procurement process adjustment but does not affect electrical performance or PCB assembly compatibility.

For Cross-Manufacturer Substitution: The P1167.123NLT from Pulse Electronics is acceptable when the CDRH74NP-120MC-B is unavailable. This part exceeds the minimum current rating (1.9 A versus 1.71 A) and provides an extended operating temperature range (-40°C ~ 130°C versus -40°C ~ 100°C). The 1 mOhm reduction in DC resistance (57 mOhm versus 58 mOhm) is within acceptable engineering tolerance. Physical dimensions increase by 0.24mm in length and width (7.54mm versus 7.30mm); PCB layout verification is required to confirm footprint compatibility. Both substitute parts maintain RoHS3 compliance and MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can the CDRH74NP-120MC-B be used as a direct replacement for the CDRH74-120MC?

A: Yes. The CDRH74NP-120MC-B is electrically and mechanically identical to the CDRH74-120MC. Both parts specify 12 µH inductance, 1.71 A current rating, 58 mOhm maximum DC resistance, shielded ferrite core, and identical physical dimensions (7.30mm × 7.30mm × 4.50mm). The primary difference is product status (Active versus Obsolete) and packaging format (Tape & Reel versus bulk). RoHS3 compliance of the substitute part represents an improvement over the original non-compliant status.

Q: What are the key differences between the CDRH74NP-120MC-B and the P1167.123NLT?

A: Both parts meet the 12 µH inductance and shielded surface mount requirements. The P1167.123NLT provides higher current rating (1.9 A versus 1.71 A), lower DC resistance (57 mOhm versus 58 mOhm), and extended temperature range (-40°C ~ 130°C versus -40°C ~ 100°C). Physical dimensions differ slightly (7.54mm × 7.54mm versus 7.30mm × 7.30mm). The P1167.123NLT uses wirewound construction, whereas the CDRH74 series uses ferrite core construction. Both are RoHS3 compliant.

Q: Is the 0.24mm increase in footprint dimensions for the P1167.123NLT a concern?

A: Footprint compatibility depends on specific PCB layout constraints. The P1167.123NLT dimensions are 7.54mm × 7.54mm compared to 7.30mm × 7.30mm for the original part. Seated height remains identical at 4.50mm maximum. PCB layout review is required to confirm that the larger footprint does not violate spacing requirements, trace routing, or component placement constraints in the target application.

Q: Are there packaging considerations when substituting the CDRH74-120MC?

A: The CDRH74NP-120MC-B is supplied in Tape & Reel (TR) format, whereas the original CDRH74-120MC packaging format is not specified. Tape & Reel packaging is standard for automated PCB assembly processes. If the original application used bulk packaging, procurement and assembly processes may require adjustment. The P1167.123NLT is also supplied in Tape & Reel format. Both substitute parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating, requiring no special storage or handling modifications.

Q: Can the P1167.123NLT be used in applications requiring the exact -40°C ~ 100°C temperature range?

A: Yes. The P1167.123NLT operating temperature range of -40°C ~ 130°C encompasses the original -40°C ~ 100°C specification. The extended upper temperature limit provides additional thermal margin and does not create incompatibility with applications designed for the narrower original range.

Q: What is the significance of the different inductance test frequencies (1 kHz versus 100 kHz)?

A: The CDRH74-120MC specifies inductance measurement at 1 kHz, while the P1167.123NLT specifies measurement at 100 kHz. Both parts are rated at 12 µH with ±20% tolerance. The test frequency difference reflects different measurement standards between manufacturers but does not affect the nominal inductance value or circuit performance when both parts are specified at 12 µH.

Q: Are there compliance differences between the substitute parts?

A: The CDRH74-120MC is RoHS non-compliant. Both substitute parts (CDRH74NP-120MC-B and P1167.123NLT) are RoHS3 compliant. All three parts are REACH Unaffected and classified as EAR99 for export control purposes. The transition to RoHS3 compliance represents a regulatory improvement and aligns with current environmental standards.
