Substitute Part Grouping Explanation

Substitute parts for the 6N136S(TA)-V are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Voltage - Isolation: 5000Vrms (exact match required)
• Number of Channels: 1 (single channel configuration)
• Output Type: Transistor with Base (identical output stage)
• Package / Case: 8-SMD, Gull Wing (mechanical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Input Type: DC (signal type compatibility)
• Voltage - Output (Max): 20V (output voltage rating)
• Current - Output / Channel: 8mA (output current capability)
• Voltage - Forward (Vf) (Typ): 1.45V (input LED forward voltage)
• Current - DC Forward (If) (Max): 25mA (input current rating)

Secondary Compatibility Parameters:

• Current Transfer Ratio range: 19% to 50% @ 16mA (transfer efficiency window)
• Operating Temperature: -55°C ~ 100°C (thermal operating range)
• RoHS Status: ROHS3 Compliant (environmental compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (handling requirements)

Substitute parts must match all primary criteria and operate within the secondary parameter ranges to ensure direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

6N136SDVM (onsemi) - Parametric Equivalent

The 6N136SDVM from onsemi matches all primary electrical and mechanical parameters with the 6N136S(TA)-V. This part demonstrates identical isolation voltage (5000Vrms), output configuration (transistor with base), channel count (1), and package specification (8-SMD, Gull Wing). The Current Transfer Ratio range (19% to 50% @ 16mA) is identical. The onsemi variant exhibits faster switching performance with Turn On/Turn Off times of 250ns and 260ns respectively, compared to 350ns and 300ns in the Everlight part. Operating temperature range is -40°C ~ 100°C, which covers the upper portion of the Everlight range. All compliance certifications (ROHS3, MSL 1) are matched. This part is suitable for direct substitution in applications where the narrower lower temperature limit (-40°C versus -55°C) is acceptable.

6N136SMT&R (Isocom) - Parametric Equivalent

The 6N136SMT&R from Isocom Components 2004 LTD provides full parametric equivalence to the 6N136S(TA)-V across all critical specifications. Isolation voltage (5000Vrms), output type (transistor with base), channel configuration (1), and package format (8-SMD, Gull Wing) are identical. Current Transfer Ratio range (19% to 50% @ 16mA) matches exactly. Operating temperature range (-55°C ~ 100°C) is identical to the Everlight part. Turn On/Turn Off times are specified as 150ns and 400ns, providing faster turn-on response compared to the Everlight part. All compliance requirements (ROHS3, MSL 1) are satisfied. This part is suitable for direct substitution without thermal or electrical derating considerations.

6N135SMT&R (Isocom) - Functional Equivalent with Parameter Variance

The 6N135SMT&R from Isocom Components 2004 LTD meets all primary mechanical and electrical isolation requirements (5000Vrms, 1 channel, transistor with base output, 8-SMD package). However, this part exhibits a lower minimum Current Transfer Ratio of 7% @ 16mA compared to 19% in the Everlight part, while maintaining the same maximum of 50% @ 16mA. This variance in the lower CTR specification may affect circuit performance in applications with tight transfer efficiency requirements. Operating temperature range (-55°C ~ 100°C) is identical. All compliance certifications match. This part is suitable for substitution in applications where the lower CTR minimum does not impact circuit function or where input drive current can be increased to compensate for lower transfer efficiency.

Frequently Asked Questions (FAQ)

Q: Can the 6N135SMT&R be used as a direct replacement for the 6N136S(TA)-V?

A: The 6N135SMT&R meets all mechanical packaging requirements (8-SMD, Gull Wing, surface mount) and electrical isolation specifications (5000Vrms, 1 channel, transistor with base output). However, the minimum Current Transfer Ratio is specified as 7% @ 16mA compared to 19% in the 6N136S(TA)-V. Direct substitution is possible if circuit design accommodates the lower minimum CTR specification or if input drive current is increased to achieve required output performance.

Q: What is the primary difference between the 6N136SDVM and 6N136SMT&R?

A: Both parts provide identical electrical isolation (5000Vrms), output configuration (transistor with base), and package format (8-SMD, Gull Wing). The 6N136SDVM from onsemi specifies an operating temperature range of -40°C ~ 100°C, while the 6N136SMT&R from Isocom specifies -55°C ~ 100°C. The 6N136SDVM exhibits faster switching times (250ns/260ns) compared to the 6N136SMT&R (150ns/400ns). Selection depends on the required lower operating temperature limit and switching speed requirements of the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 6N136S(TA)-V and all three substitute parts (6N135SMT&R, 6N136SDVM, 6N136SMT&R) are specified as ROHS3 compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What parameters must remain constant for substitution compatibility?

A: The following parameters must match exactly for functional substitution: Voltage - Isolation (5000Vrms), Number of Channels (1), Output Type (Transistor with Base), Package / Case (8-SMD, Gull Wing), Mounting Type (Surface Mount), Voltage - Output (Max) (20V), Current - Output / Channel (8mA), Voltage - Forward (Vf) (1.45V), and Current - DC Forward (If) (Max) (25mA). Current Transfer Ratio must fall within the 19% to 50% @ 16mA range for full equivalence, though lower minimums may be acceptable depending on circuit design.

Q: Can operating temperature range differences affect substitution decisions?

A: Yes. The 6N136S(TA)-V and 6N136SMT&R specify -55°C ~ 100°C, while the 6N136SDVM specifies -40°C ~ 100°C. If the application requires operation below -40°C, the 6N136SDVM is not suitable. The 6N136S(TA)-V and 6N136SMT&R are suitable for full temperature range applications. The 6N135SMT&R matches the full -55°C ~ 100°C range.

Q: How do switching time specifications affect part selection?

A: Switching times (Turn On/Turn Off) are provided for reference but do not prevent substitution if all primary electrical and mechanical parameters match. The 6N136S(TA)-V specifies 350ns/300ns, the 6N136SDVM specifies 250ns/260ns, and the 6N136SMT&R specifies 150ns/400ns. Applications with specific timing requirements should verify that substitute part switching characteristics are acceptable for the circuit design.
