CMLB063T-R36MS Equivalent & Substitute Parts

Part Overview

The CMLB063T-R36MS is a 360 nH shielded inductor manufactured by Delta Electronics/Cyntec, rated for 20 A continuous current with a maximum DC resistance of 3.8 mOhm. This component is designed for surface mount applications in high-current, low-inductance circuits requiring electromagnetic shielding. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-R36MS is determined by the following critical parameters:

Electrical Equivalence Criteria:

  • Inductance value must match 360 nH within the ±20% tolerance band
  • Inductance test frequency must be 100 kHz
  • DC resistance must not exceed 3.8 mOhm maximum
  • Current rating must support minimum 20 A continuous operation
  • Saturation current must meet or exceed 22 A

Mechanical & Environmental Criteria:

  • Shielding type must be Shielded
  • Mounting type must be Surface Mount
  • Operating temperature range must encompass -55°C to 125°C or be compatible with application limits
  • Package classification must be Nonstandard (same form factor category)
  • Height seated maximum must not exceed 0.118" (3.00mm)

Compliance Criteria:

  • RoHS3 compliance required
  • MSL rating of 1 (Unlimited) preferred for supply chain flexibility

The PA4341.361NLT qualifies as a direct substitute based on matching inductance, shielding, surface mount configuration, and compliance requirements, with documented inventory availability.

Engineering Selection Recommendations

The PA4341.361NLT is qualified as a direct substitute for the CMLB063T-R36MS based on matching inductance value, tolerance, shielding configuration, surface mount package, and compliance certifications. Both parts maintain ROHS3 compliance and MSL 1 rating.

Selection considerations based on provided specifications:

PA4341.361NLT Advantages:

  • Higher saturation current (32 A vs. 22 A) provides additional margin
  • AEC-Q200 automotive qualification available
  • Larger inventory availability (11,083 pcs vs. 712 pcs)

PA4341.361NLT Limitations:

  • Current rating 1 A lower (19 A vs. 20 A) — application must confirm 19 A adequacy
  • DC resistance 0.4 mOhm higher (4.2 mOhm vs. 3.8 mOhm) — thermal dissipation impact must be evaluated
  • Operating temperature minimum -40°C vs. -55°C — application must confirm lower temperature requirement not needed

Both parts are Active status products suitable for production use. Selection should be based on application-specific current and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can PA4341.361NLT replace CMLB063T-R36MS in all applications?

A: PA4341.361NLT is electrically and mechanically compatible for applications where the 19 A current rating and -40°C minimum operating temperature are acceptable. Applications requiring the full 20 A rating or -55°C operation must use the original CMLB063T-R36MS.

Q: What is the impact of the 0.4 mOhm higher DC resistance in PA4341.361NLT?

A: At 20 A operation, the PA4341.361NLT dissipates approximately 1.68 W (20² × 4.2 mOhm) compared to 1.52 W for CMLB063T-R36MS (20² × 3.8 mOhm). Thermal design must accommodate this 0.16 W additional dissipation.

Q: Are the physical dimensions compatible?

A: Both parts share identical height (0.118" / 3.00mm) and nonstandard package classification. Footprint dimensions differ slightly (CMLB063T-R36MS: 6.95mm × 6.60mm; PA4341.361NLT: 7.60mm × 6.90mm). PCB layout must accommodate the larger PA4341.361NLT footprint.

Q: What compliance certifications apply to each part?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating. PA4341.361NLT additionally carries AEC-Q200 automotive qualification. Both are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Why does PA4341.361NLT have higher saturation current?

A: Saturation current is determined by core material and design. PA4341.361NLT's 32 A saturation (vs. 22 A) indicates different core construction, providing additional headroom above the 20 A continuous rating for transient current events.
