Key Parameters

Substitute Part Grouping Explanation

Substitution of the H1062 is determined by the following critical parameters:

• Transformer Type & Function: Both LAN and Isolation and Data Interface (Encapsulated) transformer types serve equivalent roles in Ethernet applications
• Turns Ratio: The primary and secondary turns ratios must match or be functionally equivalent (1CT:1CT equivalent to 1:1 Transmitter, 1:1 Receiver)
• Mounting Type: Surface mount configuration must be maintained for PCB compatibility
• Physical Dimensions: Footprint and height must align with existing PCB layouts (1.125" L x 0.480" W, 0.230" max height)
• Operating Temperature Range: 0°C ~ 70°C specification must be met or exceeded
• Moisture Sensitivity Level: MSL 4 classification must be maintained for handling and storage compatibility

The H1062NL meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The H1062NL is the qualified substitute for the H1062 based on the following engineering criteria:

Product Status & Availability: The H1062 is obsolete, while the H1062NL maintains active product status with confirmed inventory availability (2049 pcs), ensuring reliable supply for new production and design revisions.

Regulatory Compliance: The H1062NL achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The original H1062 is RoHS non-compliant, making the H1062NL the appropriate choice for designs requiring compliance with modern standards.

Functional Equivalence: Both parts maintain identical physical dimensions, mounting configuration, and operating temperature specifications. The turns ratio specifications are functionally equivalent for LAN transformer applications.

Packaging & Handling: Both parts share identical MSL 4 classification, ensuring compatibility with existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the H1062NL be used as a direct replacement for the H1062 in existing designs?

A: Yes. The H1062NL maintains identical physical dimensions (1.125" L x 0.480" W, 0.230" max height), mounting type (surface mount), and operating temperature range (0°C ~ 70°C). The turns ratio specifications are functionally equivalent for LAN applications.

Q: What is the primary difference between the H1062 and H1062NL?

A: The H1062NL is an active product with ROHS3 compliance, while the H1062 is obsolete and RoHS non-compliant. The H1062NL also specifies Isolation and Data Interface (Encapsulated) transformer type versus the H1062's LAN classification, though both serve equivalent functional roles in Ethernet applications.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL) 4 classification (72 Hours), requiring the same handling, storage, and reflow procedures.

Q: Why should I transition from the H1062 to the H1062NL?

A: The H1062 is obsolete and no longer in active production. The H1062NL provides design continuity with improved regulatory compliance (ROHS3), active product status, and confirmed inventory availability.

Q: Are the packaging formats compatible?

A: The H1062 is specified with "-" packaging notation, while the H1062NL is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.
