EX2024NLT Equivalent & Substitute Parts

Part Overview

The EX2024NLT is an isolation and data interface pulse transformer manufactured by Pulse Electronics, designed for 10BASE-T LAN applications. It features a 1CT:2.5CT transmitter configuration and 1CT:1CT receiver configuration with 350µH inductance in a surface mount package. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when packaging or operational temperature requirements differ.

Substitute Part Grouping Explanation

The EX2024FNLT is identified as a direct substitute for the EX2024NLT based on the following substitution criteria:

Matching Parameters:

• Identical manufacturer (Pulse Electronics)
• Identical base product number (EX2024)
• Identical turns ratio configuration (1CT:2.5CT Transmitter, 1CT:1CT Receiver)
• Identical mounting type (Surface Mount)
• Identical RoHS3 compliance status
• Identical MSL rating (1 - Unlimited)
• Identical REACH status (REACH Unaffected)

Allowable Variations:

• Inductance: EX2024FNLT specifies 35µH, 200µH versus EX2024NLT at 350µH. This variation reflects different circuit design requirements within the LAN 10BASE-T transformer family.
• Operating Temperature: EX2024FNLT operates at -40°C ~ 85°C, providing extended temperature range compared to EX2024NLT at 0°C ~ 70°C.
• Packaging: EX2024FNLT is supplied in Cut Tape (CT) versus EX2024NLT in Tape & Reel (TR).
• Physical Dimensions: Minor dimensional differences (0.498" L x 0.350" W versus 0.500" L x 0.285" W) and height (0.200" versus 0.210").

Parameter Comparison

Engineering Selection Recommendations

Both the EX2024NLT and EX2024FNLT are active products with full RoHS3 compliance and REACH unaffected status, making them suitable for current production applications. Selection between these parts should be based on specific application requirements:

The EX2024NLT is the primary choice when the operating temperature range of 0°C ~ 70°C is sufficient and Tape & Reel packaging is required for automated assembly processes.

The EX2024FNLT provides an alternative when extended operating temperature range (-40°C ~ 85°C) is required or when Cut Tape packaging is acceptable for manual or semi-automated assembly. The dimensional variations are minimal and should be evaluated against specific PCB layout constraints.

Both parts maintain identical electrical characteristics in terms of turns ratio configuration and isolation function, with inductance variations reflecting different circuit implementations within the LAN 10BASE-T transformer product family.

Frequently Asked Questions (FAQ)

Q: Can EX2024FNLT be used as a direct replacement for EX2024NLT in all applications?

A: The EX2024FNLT shares the same turns ratio configuration and isolation function as the EX2024NLT. However, the inductance specification differs (35µH, 200µH versus 350µH), which may affect circuit performance depending on the application design. Verify that the substitute part's inductance value is compatible with your circuit requirements before implementation.

Q: What are the key differences in packaging between these parts?

A: The EX2024NLT is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly. The EX2024FNLT is supplied in Cut Tape (CT) format, suitable for lower-volume or manual assembly processes. Packaging selection should align with your production assembly capabilities.

Q: Does the extended operating temperature range of EX2024FNLT affect reliability?

A: The EX2024FNLT operates across -40°C ~ 85°C compared to the EX2024NLT at 0°C ~ 70°C. Both parts maintain identical RoHS3 compliance and MSL ratings. The extended temperature capability of the substitute part does not introduce reliability concerns; it simply provides broader operational flexibility for applications requiring wider temperature ranges.

Q: Are there physical space constraints I should consider when substituting these parts?

A: Minor dimensional differences exist between the parts. The EX2024NLT measures 0.500" L x 0.285" W x 0.210" H, while the EX2024FNLT measures 0.498" L x 0.350" W x 0.200" H. Evaluate these dimensions against your PCB layout to ensure the substitute part fits within allocated component space.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the EX2024NLT and EX2024FNLT are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Both parts are classified under ECCN EAR99 and HTSUS 8504.31.2000.
