Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDMC6D28NP-R20MC are qualified based on the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 200 nH (exact match required)
• Inductance tolerance: ±20% or tighter
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 125°C minimum
• Packaging: Tape & Reel (TR)
• RoHS3 Compliance: Required

Secondary Compatibility Parameters:

• Current rating: Equal to or greater than 17.4 A
• DC resistance: 2.5 mOhm or lower
• Saturation current (Isat): Equal to or greater than 21.7 A

Parameter Comparison

Engineering Selection Recommendations

PA4341.201NLT (Pulse Electronics): This substitute provides equivalent inductance at 200 nH with enhanced current rating of 24 A and saturation current of 41 A. DC resistance matches the main part at 2.5 mOhm maximum. The part carries AEC-Q200 qualification, indicating automotive-grade reliability. Inductance tolerance is ±30%, which is wider than the main part's ±20%. Physical dimensions are slightly larger (7.60 x 6.90 mm vs. 7.25 x 6.50 mm), and height remains at 3.00 mm maximum. ROHS3 compliance and MSL 1 rating are maintained. Product status is Active with 10,013 units in stock.

SRP7030-R20M (Bourns Inc.): This substitute maintains 200 nH inductance with ±20% tolerance matching the main part. Current rating and saturation current both exceed requirements at 24 A and 36 A respectively. DC resistance is 3 mOhm maximum, representing a 0.5 mOhm increase over the main part specification. The iron core construction differs from the metal composite core of the main part. Physical dimensions are slightly larger (7.80 x 7.00 mm), and seated height is 3.20 mm maximum. ROHS3 compliance and MSL 1 rating are maintained. Product status is Active with 2,151 units in stock.

Both substitutes maintain full compliance with operating temperature range, shielding requirements, surface mount configuration, and tape & reel packaging. Selection between substitutes depends on specific application requirements regarding DC resistance tolerance and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can PA4341.201NLT replace CDMC6D28NP-R20MC in all applications?

A: PA4341.201NLT meets the core electrical requirements of 200 nH inductance, 2.5 mOhm maximum DC resistance, and exceeds current handling specifications. The ±30% inductance tolerance is wider than the main part's ±20%. Physical dimensions are slightly larger. Compatibility depends on application tolerance requirements and available PCB space.

Q: What is the difference in DC resistance between the main part and SRP7030-R20M?

A: The main part CDMC6D28NP-R20MC specifies 2.5 mOhm maximum DC resistance, while SRP7030-R20M specifies 3 mOhm maximum. This 0.5 mOhm difference may be significant in high-current applications where resistive losses are critical.

Q: Are all three parts available in the same packaging format?

A: All three parts are supplied in Tape & Reel (TR) packaging for surface mount assembly. Physical dimensions vary slightly: CDMC6D28NP-R20MC is 7.25 x 6.50 mm, PA4341.201NLT is 7.60 x 6.90 mm, and SRP7030-R20M is 7.80 x 7.00 mm. Seated heights are 3.00 mm for the first two parts and 3.20 mm for SRP7030-R20M.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes, all three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of AEC-Q200 qualification on PA4341.201NLT?

A: AEC-Q200 is an automotive electronics qualification standard. PA4341.201NLT carries this qualification, indicating it meets automotive-grade reliability and testing requirements. The main part and SRP7030-R20M do not list this qualification.

Q: Can I use these parts interchangeably on the same PCB layout?

A: Physical dimensions differ between all three parts. CDMC6D28NP-R20MC and PA4341.201NLT have identical seated heights of 3.00 mm, while SRP7030-R20M is 3.20 mm. Footprint dimensions vary, requiring PCB layout verification before substitution.

Q: Which substitute has the highest current handling capability?

A: PA4341.201NLT provides the highest saturation current at 41 A, compared to 36 A for SRP7030-R20M and 21.7 A for the main part CDMC6D28NP-R20MC.
