Engineering Selection Recommendations

Parametric Equivalents (Broadcom Limited):

HCPL-4504-500E and HCPL-4504-560E are direct parametric equivalents with identical isolation voltage, current transfer ratio, switching times, and output specifications. Both are ROHS3 compliant and active products. Selection between these two depends on packaging preference: HCPL-4504-500E is supplied in Cut Tape & Digi-Reel format, while HCPL-4504-560E is supplied in Tape & Reel format. Both accommodate 8-DIP Gull Wing packages suitable for surface mount applications.

Manufacturer-Recommended Alternatives (Vishay & Everlight):

The Vishay 6N135 and 6N136 series, along with Everlight 6N135S1 variants, provide higher isolation voltage ratings (5000Vrms to 5300Vrms) and are ROHS3 compliant. These parts feature transistor with base output configuration, which provides additional design flexibility. The 6N136-X007 offers the fastest switching performance (200ns turn-on/off time) among alternatives. Everlight 6N135S1 variants match the original 20V output maximum and 60% maximum current transfer ratio, making them suitable for applications requiring higher performance margins.

All substitute parts maintain the 8mA output current, -55°C to 100°C operating temperature range, and single-channel configuration of the original part.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4504-500E or HCPL-4504-560E directly replace HCPL-4504#560?

A: Yes. Both parts are parametric equivalents with identical electrical specifications: 3750Vrms isolation, 25-60% current transfer ratio, 200ns/300ns switching times, and 20V maximum output. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and RoHS3 compliance status. Verify PCB footprint compatibility with the 8-DIP Gull Wing package.

Q: What are the key differences between Broadcom HCPL-4504 variants and Vishay 6N135/6N136 alternatives?

A: Broadcom HCPL-4504 parts provide 3750Vrms isolation with transistor-only output. Vishay 6N135/6N136 parts provide higher isolation (5300Vrms) with transistor-with-base output, enabling additional circuit design options. Switching performance varies: HCPL-4504 offers 200ns turn-on time, while 6N135 offers 300ns and 6N136 offers 200ns. Current transfer ratio differs: HCPL-4504 minimum is 25%, while 6N135/6N136 minimum is 7-19%.

Q: Are Everlight 6N135S1 variants suitable replacements?

A: Yes, for applications requiring 5000Vrms isolation and 20V maximum output. Everlight 6N135S1 variants match the original 60% maximum current transfer ratio and 20V output specification. Switching times are slower (350ns/500ns vs. 200ns/300ns), which may impact high-frequency applications. All variants are ROHS3 compliant and available in 8-SMD Gull Wing packaging.

Q: What packaging considerations apply when selecting substitutes?

A: The original HCPL-4504#560 uses 8-SMD Gull Wing surface mount packaging. Direct replacements HCPL-4504-500E and HCPL-4504-560E use 8-DIP Gull Wing format, requiring PCB footprint verification. Vishay 6N135-X007T, 6N135-X017, 6N135-X017T, and all Everlight 6N135S1 variants use 8-SMD Gull Wing packaging, matching the original form factor. Vishay 6N135-X007 uses 8-DIP through-hole packaging and is not suitable for surface mount applications.

Q: Which substitute offers the best performance match for high-speed applications?

A: Vishay 6N136-X007 provides the fastest switching performance with 200ns turn-on and turn-off times, matching the original HCPL-4504#560. It maintains 8-SMD Gull Wing surface mount packaging and ROHS3 compliance. Current transfer ratio is 19% minimum, which is lower than the original 25% minimum but sufficient for most applications.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original HCPL-4504#560 is RoHS non-compliant. If RoHS compliance is required for your application, select from HCPL-4504-500E, HCPL-4504-560E, or any Vishay or Everlight alternative.
