Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-901J is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 2500Vrms
• Channel configuration: 4 channels, unidirectional
• Data rate: 110MBd
• Common mode transient immunity: 15kV/µs minimum
• Supply voltage range: 3V ~ 5.5V
• Operating temperature range: -55°C ~ 125°C
• Package type: 16-SOIC (0.295", 7.50mm Width)
• Technology platform: GMR (Giant Magnetoresistive)

The HCPL-901J-000E meets all electrical and mechanical requirements for direct substitution. Both parts share identical base product number (HCPL-901) and maintain full parameter compatibility across isolation performance, signal integrity, thermal range, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-901J and HCPL-901J-000E are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on compliance and regulatory status:

The HCPL-901J carries RoHS non-compliant status, while the HCPL-901J-000E is ROHS3 compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the HCPL-901J-000E is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Current inventory availability: HCPL-901J (715 units), HCPL-901J-000E (1155 units).

Frequently Asked Questions (FAQ)

Q: Are HCPL-901J and HCPL-901J-000E electrically interchangeable?

A: Yes. Both parts maintain identical isolation voltage (2500Vrms), channel configuration (4-channel unidirectional), data rate (110MBd), common mode transient immunity (15kV/µs), supply voltage range (3V ~ 5.5V), and operating temperature range (-55°C ~ 125°C). All timing parameters including propagation delay, pulse width distortion, and rise/fall times are identical.

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

A: The primary difference is RoHS compliance status. HCPL-901J-000E is ROHS3 compliant, while HCPL-901J is RoHS non-compliant. All electrical performance and mechanical specifications are equivalent.

Q: Can I use HCPL-901J-000E as a direct replacement for HCPL-901J in existing designs?

A: Yes. The parts are pin-compatible, package-identical (16-SOIC), and electrically equivalent across all specified parameters. No circuit modifications are required.

Q: Are there any package differences between these parts?

A: No. Both parts use the same 16-SOIC (0.295", 7.50mm Width) surface mount package. The supplier device package designation differs slightly (16-SO W versus 16-SOIC), but this reflects documentation variation only and does not affect physical or electrical compatibility.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, specify HCPL-901J-000E. Both parts are in active production with stable availability.
