Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6N136-X016 is determined by the following critical parameters:

Primary Substitution Criteria:

• Isolation voltage rating (minimum 5300Vrms required)
• Output type (transistor with base connection)
• Number of channels (single channel)
• Package type (8-DIP through-hole)
• Input type (DC)
• Current transfer ratio performance (minimum 19% @ 16mA)
• Operating temperature range (-55°C ~ 100°C)

Substitute Categories:

Category 1: Direct Parametric Equivalent The 6N136-X006 from Vishay Semiconductor Opto Division matches all electrical and mechanical parameters identically to the 6N136-X016. This part is active status and represents the direct replacement.

Category 2: Manufacturer Recommended Alternatives The 6N135G and 6N136G from Isocom Components 2004 LTD provide equivalent functionality with isolation voltage of 5000Vrms (slightly lower than 5300Vrms) and higher maximum output voltage (20V vs 15V). These parts maintain the same package, channel count, and output type configuration.

Category 3: Broadcom HCPL-4562 Series The HCPL-4562-020E provides 5000Vrms isolation voltage matching the higher-voltage requirement subset. The HCPL-4562, HCPL-4562-000E, and HCPL-4562-060E variants provide 3750Vrms isolation voltage, which is lower than the 6N136-X016 specification and suitable only for applications with reduced isolation requirements. All HCPL-4562 variants use a smaller 8-DIP package (0.300", 7.62mm) compared to the 6N136-X016 (0.400", 10.16mm).

Parameter Comparison

Engineering Selection Recommendations

First Priority: 6N136-X006

The 6N136-X006 is the recommended direct replacement for the obsolete 6N136-X016. This part is manufactured by the same supplier (Vishay Semiconductor Opto Division), maintains identical electrical specifications including 5300Vrms isolation voltage and 19% minimum current transfer ratio, and uses the same 8-DIP (0.400", 10.16mm) package. The 6N136-X006 is active status with 1401 units in stock. ROHS3 compliance and MSL 1 rating match the original part exactly.

Second Priority: 6N136G (Isocom Components)

The 6N136G provides equivalent performance with 5000Vrms isolation voltage (300V lower than the original specification) and maintains the 19% minimum current transfer ratio. This part uses the same 8-DIP (0.400", 10.16mm) package and supports the full -55°C ~ 100°C operating temperature range. The 6N136G is active status with 1042 units in stock and ROHS3 compliance. Selection of this part is appropriate when the 300V reduction in isolation voltage is acceptable for the application.

Third Priority: 6N135G (Isocom Components)

The 6N135G offers 5000Vrms isolation voltage with a lower 7% minimum current transfer ratio specification. This part maintains package compatibility and full temperature range support. The 6N135G is suitable for applications where the reduced current transfer ratio specification is acceptable and isolation voltage of 5000Vrms meets requirements.

Lower Priority: HCPL-4562-020E (Broadcom)

The HCPL-4562-020E provides 5000Vrms isolation voltage matching the Isocom alternatives. However, this part uses a smaller 8-DIP (0.300", 7.62mm) package, which may require PCB layout modifications. Operating temperature range is reduced to -40°C ~ 85°C. Selection requires verification of package footprint compatibility and temperature range suitability.

Not Recommended: HCPL-4562, HCPL-4562-000E, HCPL-4562-060E

These variants provide only 3750Vrms isolation voltage, which is 1550V below the 6N136-X016 specification. These parts are suitable only for applications with significantly reduced isolation requirements and should not be selected as direct replacements.

Frequently Asked Questions (FAQ)

Q: Can the 6N136-X006 be used as a direct replacement for the 6N136-X016?

A: Yes. The 6N136-X006 is the direct parametric equivalent. Both parts are manufactured by Vishay Semiconductor Opto Division and share identical electrical specifications including 5300Vrms isolation voltage, 19% minimum current transfer ratio, 200ns switching times, and -55°C ~ 100°C operating temperature range. Both use the same 8-DIP (0.400", 10.16mm) package. The 6N136-X006 is active status, making it the recommended replacement for the obsolete 6N136-X016.

Q: What is the difference between the 6N136-X016 and the Isocom 6N136G?

A: The primary difference is isolation voltage. The 6N136-X016 provides 5300Vrms isolation, while the 6N136G provides 5000Vrms isolation. Both parts maintain the same 19% minimum current transfer ratio, 8mA output current, and -55°C ~ 100°C operating temperature range. Both use the 8-DIP (0.400", 10.16mm) package. The 6N136G is suitable for applications where 5000Vrms isolation voltage is sufficient.

Q: Why do the HCPL-4562 variants have a smaller package size?

A: The HCPL-4562 series uses an 8-DIP (0.300", 7.62mm) package, which is physically smaller than the 6N136-X016 8-DIP (0.400", 10.16mm) package. This difference requires PCB layout verification before substitution. The smaller package may not be compatible with existing board designs without modification.

Q: Can I use HCPL-4562-000E or HCPL-4562-060E as replacements?

A: These parts provide only 3750Vrms isolation voltage, which is 1550V below the 6N136-X016 specification. They are not suitable as direct replacements unless your application requirements have been reduced to 3750Vrms isolation voltage or lower. Verify isolation voltage requirements before selecting these variants.

Q: What is the impact of the reduced operating temperature range in Broadcom parts?

A: The HCPL-4562 series supports -40°C ~ 85°C operating temperature, compared to the 6N136-X016 range of -55°C ~ 100°C. If your application requires operation below -40°C or above 85°C, the Broadcom parts are not suitable. Verify your application's temperature requirements before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (6N136-X006, 6N135G, 6N136G, HCPL-4562-020E, HCPL-4562-000E, HCPL-4562-060E) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original 6N136-X016 compliance status.

Q: What is the current transfer ratio and why does it matter?

A: Current transfer ratio (CTR) is the ratio of output collector current to input LED current, expressed as a percentage. The 6N136-X016 specifies a minimum of 19% at 16mA input current. The 6N135G specifies 7% minimum, which is lower. Higher CTR values indicate more efficient signal transfer. Verify that substitute parts meet your circuit's current transfer requirements.

Q: Can I substitute based on package compatibility alone?

A: No. Package compatibility is necessary but not sufficient for substitution. Electrical parameters including isolation voltage, current transfer ratio, output voltage rating, and operating temperature range must also be verified. The HCPL-4562 series, for example, has package compatibility issues (smaller DIP size) and reduced isolation voltage (3750Vrms vs 5300Vrms).
