H5014NLT Equivalent & Substitute Parts

Part Overview

The H5014NLT is an Isolation and Data Interface (Encapsulated) Pulse Transformer manufactured by Pulse Electronics, designed for gigabit 2-port applications. This surface mount component operates across the 0°C to 70°C temperature range and is RoHS compliant with unlimited moisture sensitivity level (MSL 1). The part is currently in active production status with 1700 units available in inventory. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility is required within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The H5014FNLT qualifies as a substitute for the H5014NLT based on the following critical parameters:

Matching Parameters:

• Manufacturer: Pulse Electronics (same manufacturer ensures design compatibility)
• Turns Ratio: 1CT:1CT configuration (primary and secondary winding ratios are identical)
• Mounting Type: Surface Mount (identical PCB integration method)
• Packaging: Tape & Reel (TR) (same supply format)
• Operating Temperature Range: 0°C ~ 70°C (identical thermal operating window)
• RoHS Status: RoHS Compliant (equivalent regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)
• Product Status: Active (both parts in current production)

Distinguishing Characteristics: The H5014FNLT incorporates LAN 10/100/1000 Base-T transformer specifications with defined inductance (350µH) and explicit transmitter/receiver winding configuration, whereas the H5014NLT is specified as a general Isolation and Data Interface transformer. Both parts maintain identical electrical interface characteristics (1CT:1CT) and mechanical mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the H5014NLT and H5014FNLT maintain active production status with full RoHS compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8504.31.2000). Selection between these parts depends on application-specific requirements:

The H5014NLT serves general isolation and data interface applications with unspecified inductance characteristics. The H5014FNLT is specified for LAN 10/100/1000 Base-T applications with defined 350µH inductance and explicit transmitter/receiver winding designations. Both parts support identical 1CT:1CT turns ratios and operate within the same temperature envelope (0°C ~ 70°C).

Dimensional differences exist: the H5014FNLT has a wider footprint (0.590" versus 0.480") but slightly lower seated height (0.285" versus 0.295"). PCB layout compatibility must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can the H5014FNLT directly replace the H5014NLT in existing designs?

A: Substitution is possible when the application requirements align with LAN 10/100/1000 Base-T specifications and the PCB layout accommodates the H5014FNLT's wider footprint (0.590" W versus 0.480" W). The identical turns ratio (1CT:1CT), operating temperature range (0°C ~ 70°C), and mounting type (Surface Mount) support functional compatibility.

Q: What are the key differences between these two transformer models?

A: The H5014NLT is specified as a general Isolation and Data Interface transformer without defined inductance parameters. The H5014FNLT is specifically rated for LAN 10/100/1000 Base-T applications with 350µH inductance and explicit transmitter/receiver winding configuration. Both maintain identical electrical interface characteristics and regulatory compliance.

Q: Are there packaging or handling differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level 1 (Unlimited) ratings, requiring no special storage or handling precautions. The parts are interchangeable from a supply chain perspective.

Q: What compliance certifications apply to both parts?

A: Both the H5014NLT and H5014FNLT are RoHS Compliant, REACH Unaffected, classified as EAR99 for export control purposes, and assigned HTSUS code 8504.31.2000 for tariff classification.

Q: How do the physical dimensions affect PCB design compatibility?

A: The H5014NLT measures 1.095" L x 0.480" W with 0.295" maximum seated height. The H5014FNLT measures 1.095" L x 0.590" W with 0.285" maximum seated height. The length remains constant, but the width difference of 0.110" (2.80mm) requires PCB footprint verification before substitution.
