CDRH62NP-181MC Equivalent & Substitute Parts

Part Overview

The CDRH62NP-181MC is a 180 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This component is rated for 250 mA maximum current with a DC resistance of 3.2Ohm maximum and operates across the temperature range of -40°C to 100°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain the same inductance value, tolerance, mounting type, and physical dimensions while meeting or exceeding the electrical performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDRH62NP-181MC are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Inductance value: 180 µH (±20% tolerance)
• Mounting type: Surface Mount
• Physical dimensions: 0.260" L x 0.244" W (6.60mm x 6.20mm) footprint
• Height - Seated (Max): 0.118" (3.00mm)
• Inductance test frequency: 1 kHz

Performance Parameters (Equal or Superior):

• Current rating: minimum 250 mA
• DC resistance: maximum 3.2Ohm
• Operating temperature range: must encompass -40°C to 100°C or provide equivalent thermal performance
• RoHS3 compliance and MSL rating

The SPD62R-184M meets all critical matching parameters and exceeds electrical performance specifications with higher current rating (350 mA) and lower DC resistance (2.1Ohm maximum).

Parameter Comparison

Engineering Selection Recommendations

The SPD62R-184M is a direct functional substitute for the obsolete CDRH62NP-181MC. Both components maintain identical inductance specifications (180 µH ±20%), matching footprint dimensions (6.60mm x 6.20mm), and identical height profile (3.00mm maximum seated height). Both parts are RoHS3 compliant with MSL rating of 1 (Unlimited).

The SPD62R-184M provides superior electrical performance with a current rating of 350 mA (versus 250 mA) and reduced DC resistance of 2.1Ohm maximum (versus 3.2Ohm maximum). The substitute operates across an extended temperature range of -55°C to 125°C, encompassing the original part's -40°C to 100°C specification. The SPD62R-184M features shielded construction with ferrite drum core and wirewound design, compared to the unshielded construction of the original part.

The substitute part is currently in active production status with confirmed inventory availability (814 pieces), ensuring long-term procurement viability. The SPD62R-184M is supplied in standard Tape & Reel packaging, facilitating automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SPD62R-184M directly replace the CDRH62NP-181MC in existing designs?

A: Yes. Both parts share identical inductance values (180 µH ±20%), matching surface mount footprints (6.60mm x 6.20mm), and identical maximum seated heights (3.00mm). The SPD62R-184M meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two inductors?

A: The SPD62R-184M provides higher current rating (350 mA versus 250 mA), lower DC resistance (2.1Ohm maximum versus 3.2Ohm maximum), extended operating temperature range (-55°C to 125°C versus -40°C to 100°C), and shielded construction with ferrite drum core design. The original CDRH62NP-181MC is unshielded.

Q: Does the shielded design of the SPD62R-184M affect circuit performance?

A: Shielded construction reduces electromagnetic interference emission and susceptibility. This characteristic is beneficial in most applications and does not degrade performance relative to the unshielded original part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CDRH62NP-181MC and SPD62R-184M are RoHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the packaging difference?

A: The CDRH62NP-181MC packaging is listed as nonstandard. The SPD62R-184M is supplied in standard Tape & Reel (TR) packaging, which is compatible with automated pick-and-place assembly equipment.

Q: Is the SPD62R-184M currently available?

A: Yes. The SPD62R-184M is in active production status with 814 pieces confirmed in stock as new original inventory.

Q: Can I use the SPD62R-184M in applications requiring the lower current rating of the original part?

A: Yes. The SPD62R-184M's 350 mA current rating exceeds the 250 mA requirement of the original part, making it suitable for all applications designed for the CDRH62NP-181MC.
