Engineering Selection Recommendations
Primary Recommendation: HCPL-4562-520E
HCPL-4562-520E is the direct successor to HCPL-4562#520, manufactured by Broadcom Limited with identical electrical specifications and 8-SMD Gull Wing packaging. This part is currently active in production and ROHS3 compliant, enabling direct PCB substitution without design modification. Inventory availability is 782 units.
Secondary Recommendation (8-SMD Surface Mount, Active Status):
The 6N135-X017T and 6N135-X017 from Vishay Semiconductor Opto Division provide 5300Vrms isolation voltage (exceeding the 5000Vrms requirement) with identical 8-SMD Gull Wing packaging. Both are ROHS3 compliant and active in production. The 6N135-X017T variant in Tape & Reel packaging offers 2944 units in stock. Output voltage maximum is 15V (lower than the original 20V specification) and forward voltage is 1.33V (within acceptable tolerance of the original 1.3V).
Alternative Recommendation (8-SMD Surface Mount, Matched Isolation Voltage):
The 6N135S1(TA), 6N135S1(TB), and 6N135S1(TB)-V from Everlight Electronics Co Ltd match the original 5000Vrms isolation voltage and 20V maximum output voltage. All three variants are ROHS3 compliant, active in production, and available in 8-SMD Gull Wing packaging. Forward voltage is 1.45V (slightly higher than original 1.3V). Operating temperature range extends to -55°C ~ 100°C, exceeding the original -40°C ~ 85°C specification.
Functional Equivalent (Through-Hole Packaging):
The 6N135-X007 from Vishay Semiconductor Opto Division provides 5300Vrms isolation with 8-DIP through-hole packaging. This part requires PCB layout redesign and is not pin-compatible with the original surface mount footprint. It is ROHS3 compliant and active in production with 2171 units in stock.
Frequently Asked Questions (FAQ)
Q: Can HCPL-4562-520E be used as a direct replacement for HCPL-4562#520?
A: Yes. HCPL-4562-520E is the active production equivalent with identical electrical specifications, isolation voltage (5000Vrms), output type (transistor with base), and 8-SMD Gull Wing packaging. The primary difference is RoHS compliance status (ROHS3 compliant versus non-compliant). Direct PCB substitution is possible without layout modification.
Q: What is the difference between 6N135-X017 and 6N135-X017T?
A: Both parts are electrically identical with 5300Vrms isolation voltage and 8-SMD Gull Wing packaging. The difference is packaging format: 6N135-X017 is supplied in Tube packaging, while 6N135-X017T is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly process requirements and inventory management.
Q: Why do some substitutes have 15V maximum output voltage instead of 20V?
A: The Vishay 6N135 and 6N136 series specify 15V maximum output voltage, while the original HCPL-4562#520 and Everlight 6N135S1 variants specify 20V. This parameter difference must be evaluated against circuit requirements. If the application requires output voltages exceeding 15V, the Everlight 6N135S1 variants or HCPL-4562-520E are appropriate selections.
Q: Are all substitute parts RoHS compliant?
A: HCPL-4562-520E, all Vishay 6N135 and 6N136 variants, and all Everlight 6N135S1 variants are ROHS3 compliant. The original HCPL-4562#520 is RoHS non-compliant. If RoHS compliance is a design requirement, select from the active production alternatives listed above.
Q: What is the significance of isolation voltage differences (5000Vrms vs 5300Vrms)?
A: The original HCPL-4562#520 specifies 5000Vrms isolation. Vishay 6N135 and 6N136 series specify 5300Vrms, providing higher isolation margin. This is a beneficial parameter difference for high-voltage isolation applications. Everlight 6N135S1 variants match the original 5000Vrms specification.
Q: Can 6N135-X007 (8-DIP through-hole) be used instead of the surface mount alternatives?
A: 6N135-X007 is functionally equivalent with 5300Vrms isolation and transistor with base output. However, 8-DIP through-hole packaging requires PCB layout redesign and is not pin-compatible with the original 8-SMD surface mount footprint. Use this part only if PCB redesign is acceptable or if through-hole mounting is a design requirement.
Q: What are the operating temperature range differences?
A: The original HCPL-4562#520 operates from -40°C to 85°C. Vishay 6N135 and 6N136 variants, and Everlight 6N135S1 variants, operate from -55°C to 100°C, providing extended temperature range capability. This is beneficial for applications requiring operation at lower or higher temperatures than the original specification.
