Engineering Selection Recommendations
Primary Recommendation: HCPL-4562-500E
The HCPL-4562-500E is the direct Broadcom equivalent to the discontinued HCPL-4562#500. This part maintains identical electrical specifications including 3750Vrms isolation voltage, 20V maximum output voltage, 8mA output current, and 1.3V typical forward voltage. The HCPL-4562-500E is in active production status with ROHS3 compliance, addressing both availability and regulatory requirements. Packaging is 8-SMD, Gull Wing, matching the original part footprint. This substitution requires no circuit redesign.
Secondary Recommendations: Vishay 6N135 and 6N136 Series
The Vishay 6N135-X007T, 6N135-X017, 6N135-X017T, 6N136-X007, and 6N136-X007T optoisolators provide higher isolation voltage ratings (5300Vrms) with identical single-channel transistor output configuration and 8-SMD surface-mount packaging. These parts are in active production with ROHS3 compliance. The 6N135 series offers 7% minimum current transfer ratio at 16mA, while the 6N136 series provides 19% minimum current transfer ratio. Operating temperature range extends to -55°C ~ 100°C. Maximum output voltage is 15V, which is lower than the original 20V specification but remains suitable for most applications. Forward voltage is 1.33V typical.
Tertiary Recommendations: Everlight 6N135S1 Series
The Everlight 6N135S1(TA), 6N135S1(TB), and 6N135S1(TB)-V optoisolators provide 5000Vrms isolation voltage with 8-SMD surface-mount packaging. These parts maintain 20V maximum output voltage matching the original specification and offer 7% to 50% current transfer ratio range at 16mA. Operating temperature range is -55°C ~ 100°C. All variants are in active production with ROHS3 compliance. Forward voltage is 1.45V typical.
All recommended substitutes maintain the mandatory single-channel transistor output configuration, DC input type, 8mA output current capability, and surface-mount 8-SMD package format required for direct replacement.
Frequently Asked Questions (FAQ)
Q: Can HCPL-4562-500E be used as a direct drop-in replacement for HCPL-4562#500?
A: Yes. The HCPL-4562-500E maintains identical electrical specifications and package configuration. The primary difference is product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.
Q: What is the key difference between 6N135 and 6N136 optoisolators?
A: The 6N136 series provides higher current transfer ratio (19% minimum at 16mA) compared to the 6N135 series (7% minimum at 16mA). Both maintain identical isolation voltage, output type, and package configuration. Selection depends on circuit requirements for output current amplification.
Q: Are Vishay 6N135-X007 and 6N135-X007T interchangeable?
A: Both parts are electrically identical. The primary difference is packaging format: 6N135-X007 is supplied in Tube packaging (through-hole 8-DIP), while 6N135-X007T is supplied in Cut Tape & Digi-Reel format (surface-mount 8-SMD). For surface-mount applications matching the original HCPL-4562#500, use 6N135-X007T.
Q: What is the significance of higher isolation voltage ratings in substitute parts?
A: Substitute parts with 5000Vrms or 5300Vrms isolation ratings exceed the original 3750Vrms specification. Higher isolation voltage provides additional safety margin and is fully compatible with circuits designed for 3750Vrms isolation. No derating or circuit modification is required.
Q: Can I use 6N135-X007 (8-DIP through-hole) in place of HCPL-4562#500 (8-SMD surface-mount)?
A: No. The 6N135-X007 uses through-hole 8-DIP package configuration, which is mechanically incompatible with surface-mount PCB layouts designed for 8-SMD components. Use 6N135-X007T (8-SMD surface-mount) for direct footprint compatibility.
Q: What is the impact of lower maximum output voltage in Vishay parts (15V vs. 20V)?
A: Vishay 6N135 and 6N136 series have 15V maximum output voltage compared to the original 20V specification. This is acceptable for most applications but must be verified against circuit requirements. If the application requires output voltages exceeding 15V, use Everlight 6N135S1 series (20V maximum) or Broadcom HCPL-4562-500E (20V maximum).
Q: Are all substitute parts RoHS compliant?
A: The original HCPL-4562#500 is RoHS non-compliant. All recommended substitutes (HCPL-4562-500E, Vishay 6N135/6N136 series, and Everlight 6N135S1 series) are ROHS3 compliant, meeting current regulatory requirements.
Q: What is the difference between Everlight 6N135S1(TA), 6N135S1(TB), and 6N135S1(TB)-V?
A: All three variants maintain identical electrical specifications including 5000Vrms isolation voltage, 20V maximum output voltage, and 8-SMD surface-mount package. Differences are designated by suffix codes (TA, TB, TB-V) which indicate manufacturing or packaging variations. Electrical performance is equivalent across all three variants.
