Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-090J is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 2500Vrms
• Channel count and configuration: 4 unidirectional channels
• Data rate: 110MBd
• Common mode transient immunity: 15kV/µs minimum
• Supply voltage range: 3V ~ 5.5V
• Package type: 16-SOIC (0.154", 3.90mm Width)
• Technology platform: GMR (Giant Magnetoresistive)
• Operating temperature range: -55°C ~ 125°C

The substitute part HCPL-090J-000E maintains identical electrical and mechanical specifications, differing only in RoHS compliance status and inventory availability. Both parts share the same base product number (HCPL-090) and are manufactured by Broadcom Limited.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-090J and HCPL-090J-000E are functionally equivalent and electrically interchangeable for all applications requiring 2500Vrms 4-channel digital isolation at 110MBd data rates.

Selection between these parts should be based on compliance requirements:

• HCPL-090J-000E is the preferred choice for applications subject to RoHS3 compliance mandates or procurement policies requiring lead-free manufacturing processes.
• HCPL-090J remains suitable for applications without RoHS compliance requirements.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility. Inventory availability differs, with HCPL-090J-000E offering higher stock levels (2300 pieces versus 1233 pieces).

Frequently Asked Questions (FAQ)

Q: Are HCPL-090J and HCPL-090J-000E pin-for-pin compatible?

A: Yes. Both parts use the 16-SOIC (0.154", 3.90mm Width) package with identical pinout and electrical characteristics. Direct substitution is possible without circuit modification.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. HCPL-090J-000E is ROHS3 compliant, while HCPL-090J is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use HCPL-090J-000E in place of HCPL-090J?

A: Yes. HCPL-090J-000E is a direct substitute with superior compliance certification. No design changes are required.

Q: Can I use HCPL-090J in place of HCPL-090J-000E?

A: Electrical substitution is possible; however, this may violate procurement policies or regulatory requirements if RoHS3 compliance is mandated for your application.

Q: What does the "-000E" suffix indicate?

A: The "-000E" suffix denotes a specific manufacturing variant with RoHS3 compliance certification. The base product number HCPL-090 remains consistent across both variants.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance, including isolation voltage, data rate, propagation delay, and common mode transient immunity specifications.

Q: What is the isolation voltage rating?

A: Both parts provide 2500Vrms galvanic isolation, suitable for high-voltage separation applications requiring robust noise immunity.

Q: What is the maximum data rate?

A: Both parts support 110MBd (megabits per second) data rate with 15ns maximum propagation delay.
