Key Parameters

Substitute Part Grouping Explanation

The HCPL-901J-500E qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Isolation voltage: 2500Vrms (exact match required)
• Number of channels: 4 (exact match required)
• Data rate: 110MBd (exact match required)
• Common mode transient immunity: 15kV/µs (exact match required)
• Supply voltage range: 3V ~ 5.5V (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Package type: 16-SOIC (0.295", 7.50mm Width) (exact match required)
• Mounting type: Surface Mount (exact match required)

The HCPL-901J-500E maintains all specified electrical characteristics and physical form factor, enabling direct substitution in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-901J-500E is the direct substitute for the discontinued HCPL-901J-500. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility.

Key differentiation factors:

• Product Status: HCPL-901J-500 is discontinued; HCPL-901J-500E is active and available
• RoHS Compliance: HCPL-901J-500 is RoHS non-compliant; HCPL-901J-500E is ROHS3 compliant
• Packaging: HCPL-901J-500 is supplied in standard packaging; HCPL-901J-500E is supplied in Tape & Reel (TR) format
• Inventory: HCPL-901J-500E has higher availability (1013 Pcs vs 728 Pcs)

For new designs or component replenishment, HCPL-901J-500E is the appropriate selection due to active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can HCPL-901J-500E be used as a direct replacement for HCPL-901J-500?

A: Yes. Both parts are electrically and mechanically identical, with identical isolation voltage (2500Vrms), channel count (4), data rate (110MBd), CMTI (15kV/µs), supply voltage range (3V ~ 5.5V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package dimensions. Pin-for-pin substitution is valid.

Q: What is the difference between HCPL-901J-500 and HCPL-901J-500E?

A: The primary differences are product status, RoHS compliance, and packaging format. HCPL-901J-500 is discontinued and RoHS non-compliant, while HCPL-901J-500E is active, ROHS3 compliant, and supplied in Tape & Reel format.

Q: Are there packaging considerations when switching to HCPL-901J-500E?

A: HCPL-901J-500E is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. Both parts use the same 16-SOIC (0.295", 7.50mm Width) package case, so PCB footprints and assembly processes remain unchanged.

Q: What is the isolation voltage rating for these parts?

A: Both HCPL-901J-500 and HCPL-901J-500E provide 2500Vrms isolation voltage, suitable for high-voltage isolation applications.

Q: What is the maximum data rate for these digital isolators?

A: Both parts support 110MBd data rate with 15kV/µs common mode transient immunity.
