Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6N136M is determined by the following critical parameters:

• Isolation Voltage: 5000Vrms minimum (parts with lower isolation voltage are not suitable)
• Output Configuration: Transistor with base output (required for circuit compatibility)
• Package Type: 8-DIP through-hole (physical and electrical interface requirement)
• Number of Channels: Single channel (functional requirement)
• Current Transfer Ratio Range: Minimum 19% @ 16mA (performance specification)
• Maximum Output Current: 8mA per channel (load capability)
• Maximum Output Voltage: 20V (voltage rating)

Substitute parts are grouped into two categories based on isolation voltage compliance:

Category A - Full 5000Vrms Isolation: 6N136G, 6N135G, HCNW136-000E, HCNW4562-000E

Category B - Reduced Isolation (3750Vrms): HCPL-4562-000E (suitable only for applications not requiring full 5000Vrms isolation)

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (5000Vrms Isolation, 8-DIP 0.400" Package)

6N136G and 6N135G from Isocom Components 2004 LTD maintain full electrical compatibility with the 6N136M. Both parts are ROHS3 compliant and offer extended operating temperature ranges (-55°C ~ 100°C). The 6N136G provides identical current transfer ratio specifications (19% to 50% @ 16mA), while 6N135G features a lower minimum CTR (7% @ 16mA). Both are suitable for direct substitution in applications requiring the full 5000Vrms isolation specification.

HCNW136-000E from Broadcom Limited is a 5000Vrms equivalent with ROHS3 compliance and REACH unaffected status. This part specifies a 15% minimum current transfer ratio and operates across -55°C ~ 85°C. It is suitable for applications where Broadcom component qualification is required.

HCNW4562-000E from Broadcom Limited maintains 5000Vrms isolation with ROHS3 compliance and REACH unaffected status. Operating temperature range is -40°C ~ 85°C, matching the 6N136M specification. This part is suitable for direct substitution where Broadcom sourcing is preferred.

Reduced Isolation Alternative (3750Vrms Isolation, 8-DIP 0.300" Package)

HCPL-4562-000E from Broadcom Limited provides 3750Vrms isolation in an 8-DIP package with reduced pitch (0.300" vs. 0.400"). This part is ROHS3 compliant with REACH unaffected status. The reduced isolation voltage and different package dimensions make this suitable only for applications not requiring full 5000Vrms isolation and where PCB layout accommodates the smaller package footprint.

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the 6N136M.

Frequently Asked Questions (FAQ)

Q: Can 6N135G be used as a direct replacement for 6N136M?

A: 6N135G is electrically compatible with 6N136M in terms of isolation voltage (5000Vrms), output configuration (transistor with base), package type (8-DIP 0.400"), and output ratings (20V max, 8mA per channel). The primary difference is the minimum current transfer ratio specification (7% vs. 19%), which may affect circuit performance in applications with tight CTR requirements. Verify circuit design margins before substitution.

Q: What is the key difference between HCNW4562-000E and HCPL-4562-000E?

A: Both parts are Broadcom optoisolators with transistor base output. The critical difference is isolation voltage: HCNW4562-000E provides 5000Vrms isolation, while HCPL-4562-000E provides 3750Vrms isolation. Additionally, HCPL-4562-000E uses an 8-DIP package with 0.300" pitch compared to the standard 0.400" pitch, requiring different PCB footprints. Select based on isolation voltage requirements and available PCB layout space.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all substitute parts listed (6N136G, 6N135G, HCNW136-000E, HCNW4562-000E, HCPL-4562-000E) are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the 6N136M compliance profile.

Q: Can HCPL-4562-000E be used in a 5000Vrms isolation application?

A: No. HCPL-4562-000E provides only 3750Vrms isolation, which is insufficient for applications requiring 5000Vrms isolation. Use this part only in applications where the lower isolation voltage meets design requirements. Additionally, the different package pitch (0.300" vs. 0.400") requires PCB layout modification.

Q: Which substitute offers the widest operating temperature range?

A: Both 6N136G and 6N135G from Isocom Components 2004 LTD offer the widest operating temperature range of -55°C ~ 100°C, compared to the 6N136M specification of -40°C ~ 85°C. These parts are suitable for applications requiring extended temperature operation.

Q: What is the significance of current transfer ratio (CTR) differences between substitutes?

A: Current transfer ratio determines the output current relative to input current. The 6N136M specifies 19% to 50% CTR @ 16mA. Substitutes with lower minimum CTR (such as 6N135G at 7%) may produce lower output currents for the same input, potentially affecting circuit gain and switching characteristics. Verify circuit design accommodates the CTR specification of the selected substitute.

Q: Are Broadcom parts (HCNW series, HCPL series) pin-compatible with Lite-On 6N136M?

A: Yes, all listed Broadcom parts maintain the same 8-DIP through-hole package configuration and pin assignment as the 6N136M, with the exception of HCPL-4562-000E, which uses a different package pitch (0.300" vs. 0.400"). Verify PCB footprint compatibility before substitution.
