CDMC104NP-R56M Equivalent & Substitute Parts

Part Overview

The CDMC104NP-R56M is a 560 nH shielded inductor manufactured by Sumida America Components Inc., rated for 21 A continuous current with a DC resistance of 1.48 mOhm. This component features a metal composite core and is housed in a nonstandard surface mount package measuring 11.50mm × 10.00mm × 4.00mm. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and procurement requirements. Substitute parts must maintain electrical performance within the specified inductance tolerance and current handling capabilities while meeting RoHS3 compliance and MSL Level 1 requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDMC104NP-R56M is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 560 nH with ±20% tolerance
• Shielding: Shielded construction required
• Mounting type: Surface mount only
• Package dimensions: 11.50mm × 10.00mm footprint with 4.00mm maximum height
• RoHS3 compliance and MSL Level 1 rating

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 21 A continuous rating
• DC resistance: Substitute DCR must not exceed 1.48 mOhm nominal specification
• Operating temperature range: Substitute must cover minimum -40°C to 125°C
• Core material: Metal composite or metal core acceptable
• Saturation current: Substitute Isat must equal or exceed 22 A

The two identified substitute parts meet these criteria while offering active product status and improved availability compared to the obsolete CDMC104NP-R56M.

Parameter Comparison

Engineering Selection Recommendations

104CDMCCDS-R56MC (Sumida America Components Inc.)

This substitute maintains manufacturer continuity with the original CDMC104NP-R56M while offering active product status. The part exceeds the minimum current rating requirement (27 A vs. 21 A) and provides enhanced saturation current (40 A vs. 22 A). The DC resistance specification of 1.8 mOhm maximum represents a 0.32 mOhm increase from the original 1.48 mOhm, which remains within acceptable tolerance for most applications. Extended operating temperature range (-55°C to 125°C) provides additional thermal margin. Footprint compatibility is exact at 11.50mm × 10.00mm. Tape & Reel packaging supports high-volume production requirements. ROHS3 compliance and MSL Level 1 rating are maintained.

PA4342.561NLT (Pulse Electronics)

This substitute offers the highest inventory availability (5741 pieces) and active product status. Current rating of 25 A and saturation current of 40 A both exceed original specifications. DC resistance specification of 1.8 mOhm maximum is identical to the first substitute. Operating temperature range matches the original specification (-40°C to 125°C). Footprint width is 10.30mm, representing a 0.30mm increase from the original 10.00mm; height and length dimensions remain compatible. Tape & Reel packaging supports production scalability. ROHS3 compliance and MSL Level 1 rating are maintained. REACH Unaffected status is documented.

Both substitutes satisfy all mandatory electrical and mechanical criteria. Selection between them depends on specific application requirements regarding temperature range, footprint tolerance, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 104CDMCCDS-R56MC be used as a direct replacement for the CDMC104NP-R56M?

A: Yes. Both parts share identical inductance (560 nH ±20%), shielding configuration, operating temperature range (-40°C to 125°C), and package footprint (11.50mm × 10.00mm × 4.00mm). The substitute exceeds the original current rating and saturation current specifications. DC resistance increases from 1.48 mOhm to 1.8 mOhm maximum, which is within acceptable tolerance for most circuit designs.

Q: What is the primary difference between the two substitute parts?

A: The 104CDMCCDS-R56MC is manufactured by Sumida (original manufacturer) and offers an extended operating temperature range of -55°C to 125°C. The PA4342.561NLT is manufactured by Pulse Electronics and provides significantly higher inventory availability (5741 pieces vs. 880 pieces). Both parts meet all electrical specifications and have identical DC resistance maximums of 1.8 mOhm.

Q: Does the PA4342.561NLT footprint width of 10.30mm create compatibility issues?

A: The 0.30mm width increase from 10.00mm to 10.30mm is within typical PCB design tolerances for surface mount components. Verify that the target PCB pad layout accommodates this dimension before implementation. Length (11.50mm) and height (4.00mm) dimensions remain identical to the original part.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the 104CDMCCDS-R56MC and PA4342.561NLT are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original CDMC104NP-R56M specification.

Q: What is the impact of the increased DC resistance in the substitute parts?

A: DC resistance increases from 1.48 mOhm (original) to 1.8 mOhm maximum (both substitutes). At the rated 21 A current, this represents an additional power dissipation of approximately 0.0672 mW. For most applications, this increase is negligible; however, designs with strict thermal or efficiency requirements should evaluate this parameter against circuit specifications.

Q: Can either substitute part handle higher current than the original?

A: Yes. The 104CDMCCDS-R56MC is rated for 27 A continuous current with 40 A saturation current. The PA4342.561NLT is rated for 25 A continuous current with 40 A saturation current. Both exceed the original 21 A / 22 A specification and can be used in applications requiring higher current capacity.

Q: What packaging formats are available for these substitutes?

A: Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original CDMC104NP-R56M was available in Cut Tape (CT) & Digi-Reel® format. Verify that your assembly process supports Tape & Reel packaging.
