CDMC104NP-R36M Equivalent & Substitute Parts

Part Overview

The CDMC104NP-R36M is a 360 nH shielded inductor manufactured by Sumida America Components Inc., rated for 25 A continuous current with 1.1 mOhm DC resistance. This surface mount component features a metal composite core and is designed for high-current applications requiring low DC resistance and electromagnetic shielding. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Substitute Part Grouping Explanation

Substitution of the CDMC104NP-R36M is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Inductance value: 360 nH with ±20% tolerance
• Shielding requirement: Shielded construction
• Mounting type: Surface Mount
• Package dimensions: Nonstandard form factor (11.50 mm × 10.00 mm footprint, 4.00 mm maximum height)
• RoHS3 compliance and MSL 1 rating

Current and Resistance Considerations: Substitute parts must maintain current ratings and DC resistance values within acceptable operating margins. The original part specifies 25 A continuous current with 1.1 mOhm DCR. Substitutes with higher current ratings and comparable or lower DCR values are acceptable for direct replacement, as they provide equal or superior performance in the same application context.

Temperature and Frequency Parameters: All substitutes operate within the -40°C to 125°C range. Test frequency variations (1 MHz vs. 100 kHz) do not preclude substitution, as inductance value remains constant across the specified frequency range.

Engineering Selection Recommendations

104CDMCCDS-R36MC (Sumida America Components Inc.)

This substitute is manufactured by the same supplier as the original part and maintains identical inductance, tolerance, and package footprint dimensions. The part features an extended operating temperature range (-55°C to 125°C) and higher current ratings (32 A continuous, 52 A saturation) compared to the original. DC resistance is specified at 1.2 mOhm maximum, representing a 0.1 mOhm increase from the original 1.1 mOhm specification. This part is active in production with substantial inventory availability (18,139 pcs). Packaging is provided in Tape & Reel format. ROHS3 compliance and MSL 1 rating are maintained.

PA4342.361NLT (Pulse Electronics)

This substitute provides equivalent electrical performance with 31 A continuous current rating and 60 A saturation current. The package width is 10.30 mm, representing a 0.30 mm increase from the original 10.00 mm width. All other dimensions remain within specification. DC resistance is 1.2 mOhm maximum. The part is active in production with 985 pcs available inventory. ROHS3 compliance, MSL 1 rating, and REACH unaffected status are confirmed. Operating temperature range matches the original specification (-40°C to 125°C).

Both substitutes satisfy the core electrical requirements and maintain mechanical compatibility within the specified nonstandard package envelope. Selection between these alternatives depends on PCB layout constraints and supplier preference.

Frequently Asked Questions (FAQ)

Q: Can the 104CDMCCDS-R36MC replace the CDMC104NP-R36M in existing designs?

A: Yes. Both parts share identical inductance (360 nH ±20%), shielding, and package footprint (11.50 mm × 10.00 mm × 4.00 mm). The substitute provides higher current ratings (32 A vs. 25 A) and extended temperature range (-55°C to 125°C vs. -40°C to 125°C), making it suitable for direct substitution. DC resistance increases from 1.1 mOhm to 1.2 mOhm maximum, which is acceptable for most applications.

Q: What is the difference between the PA4342.361NLT and the Sumida substitute?

A: Both parts meet the core electrical specification (360 nH, ±20%, shielded, surface mount). The PA4342.361NLT has a slightly wider package (10.30 mm vs. 10.00 mm) and is manufactured by Pulse Electronics rather than Sumida. Current ratings are comparable (31 A vs. 32 A). Selection depends on PCB layout tolerance and supplier availability.

Q: Are there any package dimension concerns with the PA4342.361NLT?

A: The PA4342.361NLT width is 10.30 mm compared to the original 10.00 mm specification. This 0.30 mm difference must be evaluated against PCB layout constraints and component spacing requirements. Length (11.50 mm) and height (4.00 mm maximum) remain identical to the original part.

Q: Do all three parts meet RoHS3 compliance?

A: Yes. The original CDMC104NP-R36M and both substitutes (104CDMCCDS-R36MC and PA4342.361NLT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the product status change from Obsolete to Active?

A: The original CDMC104NP-R36M is classified as obsolete, meaning it is no longer manufactured and existing inventory will eventually deplete. Both substitute parts are active in production, ensuring long-term availability for new designs and ongoing production requirements.

Q: How do the DC resistance specifications compare?

A: The original part specifies 1.1 mOhm DCR. Both substitutes specify 1.2 mOhm maximum DCR, representing a 0.1 mOhm increase. This difference is negligible in most power delivery and filtering applications and does not preclude substitution.

Q: Can the higher saturation current ratings of the substitutes affect circuit performance?

A: No. Higher saturation current ratings (52 A for 104CDMCCDS-R36MC and 60 A for PA4342.361NLT compared to 28 A for the original) indicate improved performance margin. These parts will not saturate at lower current levels and provide equal or superior performance in the same application context.
