Parameter Comparison

Engineering Selection Recommendations

6N136G (Isocom Components 2004 LTD) - Parametric Equivalent:

The 6N136G is a parametric equivalent to the 6N136M. Both components share identical electrical specifications including 5000Vrms isolation voltage, 19-50% current transfer ratio at 16mA, 1.45V forward voltage, and 25mA maximum DC forward current. Both operate across the -55°C to 100°C temperature range and utilize identical 8-DIP (0.400", 10.16mm) through-hole packaging. Both are RoHS3 compliant with MSL 1 rating and Active product status. This part is suitable for direct substitution in applications where the 6N136M is specified.

HCPL-4562-000E (Broadcom Limited) - Similar Substitute:

The HCPL-4562-000E is a similar substitute with the following considerations. The isolation voltage is 3750Vrms, which is lower than the 6N136M specification of 5000Vrms. The operating temperature range is -40°C to 85°C, narrower than the 6N136M range of -55°C to 100°C. The maximum DC forward current is 12mA, lower than the 6N136M specification of 25mA. The package footprint is 8-DIP (0.300", 7.62mm), which differs from the 6N136M 8-DIP (0.400", 10.16mm) form factor. Both components share identical output voltage maximum of 20V, output current of 8mA per channel, and are RoHS3 compliant with MSL 1 rating and Active product status. This part is suitable for substitution only in applications where the lower isolation voltage, narrower temperature range, and reduced forward current specifications are acceptable, and where the smaller package footprint is compatible with PCB layout.

Frequently Asked Questions (FAQ)

Q1: Can the 6N136G be used as a direct replacement for the 6N136M?

A: Yes. The 6N136G is a parametric equivalent with identical electrical and thermal specifications. Both components feature 5000Vrms isolation, 19-50% current transfer ratio, -55°C to 100°C operating temperature, and identical 8-DIP (0.400", 10.16mm) through-hole packaging. Both are RoHS3 compliant and Active status. Direct substitution is supported without design modification.

Q2: What are the limitations of using HCPL-4562-000E as a substitute for 6N136M?

A: The HCPL-4562-000E has three key limitations. First, isolation voltage is 3750Vrms versus 5000Vrms for the 6N136M, reducing isolation performance. Second, operating temperature range is -40°C to 85°C versus -55°C to 100°C, limiting operation in extreme temperature environments. Third, maximum DC forward current is 12mA versus 25mA, reducing input drive capability. Additionally, the package footprint is 8-DIP (0.300", 7.62mm) versus 8-DIP (0.400", 10.16mm), requiring PCB layout verification for compatibility.

Q3: Are all substitute parts RoHS3 compliant?

A: Yes. Both the 6N136G and HCPL-4562-000E are RoHS3 compliant, matching the 6N136M compliance status. All three parts carry MSL 1 (Unlimited) moisture sensitivity level rating.

Q4: What is the difference in package dimensions between the main part and substitutes?

A: The 6N136M and 6N136G both use 8-DIP (0.400", 10.16mm) packaging. The HCPL-4562-000E uses 8-DIP (0.300", 7.62mm) packaging, which is a smaller form factor. PCB footprint compatibility must be verified before substitution.

Q5: Which substitute part maintains the widest operating temperature range?

A: Both the 6N136M and 6N136G maintain the widest operating temperature range of -55°C to 100°C. The HCPL-4562-000E operates within -40°C to 85°C, a narrower range.

Q6: Can HCPL-4562-000E be used in high-isolation applications?

A: The HCPL-4562-000E provides 3750Vrms isolation, which is lower than the 6N136M specification of 5000Vrms. Applications requiring 5000Vrms isolation must use either the 6N136M or 6N136G.
