Key Parameters

Substitute Part Grouping Explanation

The PA4343.222NLT from Pulse Electronics is listed as a direct substitute based on the following criteria:

The substitution relationship is established through alignment of core electrical parameters within acceptable tolerances. Both parts feature shielded construction, surface mount configuration, and identical inductance tolerance of ±20%. Both components operate across overlapping temperature ranges and maintain ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

However, critical differences exist in current handling capacity and DC resistance. The PA4343.222NLT exhibits significantly higher current rating (22 A versus 7 A) and substantially lower DC resistance (4.2 mOhm versus 39 Ohm). These differences indicate the substitute part is suitable only for applications where the CMLB136T-220MS current and resistance specifications exceed actual circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection between CMLB136T-220MS and PA4343.222NLT must be based on circuit current requirements and DC resistance specifications. The CMLB136T-220MS is the primary component with specified ratings of 7 A continuous current and 39 Ohm maximum DC resistance. The PA4343.222NLT presents different electrical characteristics: 22 A current rating and 4.2 mOhm DC resistance, with a notably different inductance value of 2.2 µH.

Both components maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). The PA4343.222NLT includes AEC-Q200 automotive qualification, which the CMLB136T-220MS does not specify. Temperature operating range differs slightly, with the CMLB136T-220MS supporting extended low-temperature operation to -55°C compared to -40°C for the PA4343.222NLT.

Component selection must verify that circuit design parameters align with the specific electrical ratings of the chosen part, particularly regarding current handling and resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can PA4343.222NLT directly replace CMLB136T-220MS in all applications?

A: No. While both parts share shielded surface mount construction and identical inductance tolerance, the PA4343.222NLT has different inductance (2.2 µH vs. 22 µH), higher current rating (22 A vs. 7 A), and significantly lower DC resistance (4.2 mOhm vs. 39 Ohm). Substitution is valid only when circuit requirements fall within the PA4343.222NLT specifications.

Q: What are the key electrical differences between these parts?

A: The primary differences are inductance value (10:1 ratio), current handling capacity (3.1:1 ratio), and DC resistance (9,286:1 ratio). These differences reflect different design objectives and core materials. The PA4343.222NLT uses molded construction while the CMLB136T-220MS uses metal core construction.

Q: Are both parts RoHS compliant?

A: Yes. Both CMLB136T-220MS and PA4343.222NLT are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Both are REACH unaffected and classified as EAR99 for export control purposes.

Q: What is the temperature operating range difference?

A: CMLB136T-220MS operates from -55°C to 125°C, while PA4343.222NLT operates from -40°C to 125°C. The CMLB136T-220MS supports 15°C lower minimum temperature operation.

Q: Does the PA4343.222NLT have additional certifications?

A: Yes. The PA4343.222NLT includes AEC-Q200 automotive qualification, which is not specified for the CMLB136T-220MS. This certification indicates suitability for automotive applications with defined reliability standards.

Q: How do package dimensions compare?

A: Both parts use nonstandard surface mount packages with similar footprints. CMLB136T-220MS measures 13.45mm × 12.60mm × 6.00mm (max height). PA4343.222NLT measures 14.00mm × 12.80mm × 6.50mm (max height). Dimensional differences are minimal and typically accommodate standard PCB layouts.
