Engineering Selection Recommendations
For Direct PCB Replacement (8-SMD Surface Mount):
The 6N135-X017T and 6N136-X007T are the primary substitutes. Both are active products with ROHS3 compliance and identical 8-SMD, Gull Wing packaging. The 6N135-X017T maintains the 5300Vrms isolation rating and all critical electrical parameters. The 6N136-X007T offers higher current transfer ratio (19% @ 16mA vs. 7% @ 16mA) and faster switching times (200ns vs. 300ns), providing improved performance margins.
For Designs with 20V Output Requirement:
The Everlight 6N135S1(TA), 6N135S1(TB), and 6N135S1(TB)-V maintain the original 20V maximum output voltage specification. These parts are active products with ROHS3 compliance and 8-SMD surface mount packaging. Current transfer ratio ranges from 7% to 50% @ 16mA, providing wider operational flexibility.
For Through-Hole Applications:
The 6N135-X007 is available in 8-DIP through-hole package with 5300Vrms isolation rating and active product status. This option is suitable only for designs that can accommodate through-hole mounting.
Compliance Consideration:
All substitute parts listed are ROHS3 compliant, whereas the original HCPL-4562#320 is RoHS non-compliant. This represents an improvement in environmental compliance for new designs and production runs.
Frequently Asked Questions (FAQ)
Q: Can the 6N135-X017T directly replace the HCPL-4562#320 on existing PCBs?
A: Yes. Both parts use 8-SMD, Gull Wing surface mount packaging with identical pinout for transistor with base output configuration. Electrical parameters are compatible within design tolerances.
Q: What is the difference between 6N135 and 6N136 series optoisolators?
A: The primary difference is current transfer ratio. The 6N135 series has 7% minimum CTR @ 16mA, while the 6N136 series has 19% minimum CTR @ 16mA. The 6N136 provides faster switching times (200ns vs. 300ns). Selection depends on circuit requirements for gain and switching speed.
Q: Why do some substitutes have 5300Vrms isolation instead of 5000Vrms?
A: Higher isolation voltage ratings provide additional safety margin and are functionally compatible with designs specified for 5000Vrms. The 5300Vrms rating exceeds the original specification and does not create compatibility issues.
Q: Are the Everlight 6N135S1 variants suitable replacements?
A: Yes. The 6N135S1(TA), 6N135S1(TB), and 6N135S1(TB)-V maintain the original 5000Vrms isolation and 20V output voltage specifications. All are active products with ROHS3 compliance and 8-SMD surface mount packaging.
Q: What is the impact of different operating temperature ranges?
A: Substitute parts with -55°C ~ 100°C operating range exceed the original -40°C ~ 85°C specification. This provides wider operational margin and is compatible with designs specified for the narrower range.
Q: Can I use the 6N135-X007 (through-hole) as a substitute?
A: The 6N135-X007 is electrically compatible but requires PCB redesign due to different package type (8-DIP through-hole vs. 8-SMD surface mount). Use only if PCB layout can accommodate through-hole mounting.
Q: What is the significance of packaging variants (Tube, Cut Tape, Tape & Reel)?
A: Packaging variants affect order quantities and handling but do not impact electrical performance. Select based on production volume and assembly process requirements. The base part number (6N135-X017, 6N135-X017T) remains identical; packaging suffix (-X007, -X007T) indicates the distribution format.
