Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6N136S(TA) is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor with Base
• Package / Case: 8-SMD, Gull Wing
• Mounting Type: Surface Mount
• Input Type: DC

Allowable Parameter Ranges:

• Current Transfer Ratio (Min): 7% to 19% @ 16mA
• Current Transfer Ratio (Max): 50% @ 16mA
• Voltage - Output (Max): 20V
• Current - Output / Channel: 8mA
• Voltage - Forward (Vf) (Typ): 1.45V
• Current - DC Forward (If) (Max): 25mA
• Operating Temperature: -40°C to -55°C minimum, 100°C maximum

Three substitute parts meet these criteria and are classified as follows:

Similar Manufacturer Part: 6N135SMT&R (Isocom Components 2004 LTD) - Matches all mandatory parameters with Current Transfer Ratio (Min) of 7% @ 16mA.

Similar Manufacturer Part: 6N136SDVM (onsemi) - Matches all mandatory parameters with identical Current Transfer Ratio specifications and improved switching times.

Parametric Equivalent: 6N136SMT&R (Isocom Components 2004 LTD) - Matches all mandatory parameters with identical electrical specifications and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - 6N136SDVM (onsemi): The 6N136SDVM is the closest functional equivalent to the 6N136S(TA). Both parts share identical Current Transfer Ratio specifications (19% minimum, 50% maximum @ 16mA) and matching isolation voltage. The onsemi variant demonstrates improved switching performance with Turn On Time of 250ns and Turn Off Time of 260ns compared to the Everlight original. The 6N136SDVM operates across -40°C to 100°C, which covers the majority of industrial temperature applications. ROHS3 compliance and MSL 1 rating confirm environmental and moisture handling equivalence. Current inventory of 1,969 units supports production requirements.

Secondary Selection - 6N136SMT&R (Isocom Components 2004 LTD): The 6N136SMT&R provides parametric equivalence with identical electrical specifications and extended operating temperature range (-55°C to 100°C). This part matches the original 6N136S(TA) across all critical parameters including Current Transfer Ratio and isolation voltage. The Isocom variant offers the fastest Turn On Time at 150ns, beneficial for high-speed switching applications. ROHS3 compliance and MSL 1 rating confirm regulatory alignment. Inventory of 2,188 units ensures availability.

Tertiary Selection - 6N135SMT&R (Isocom Components 2004 LTD): The 6N135SMT&R functions as a substitute with reduced Current Transfer Ratio minimum specification (7% @ 16mA versus 19%). This part maintains all mandatory parameters including 5000Vrms isolation, single-channel transistor output, and 8-SMD surface mount packaging. Selection of this part requires circuit design confirmation that the lower minimum CTR does not impact system performance. ROHS3 compliance and MSL 1 rating confirm environmental standards. Inventory of 1,967 units is available.

All substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, confirming regulatory and manufacturing process equivalence to the original 6N136S(TA).

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 6N136S(TA)?

A: Substitution requires matching isolation voltage (5000Vrms), single-channel configuration, transistor with base output type, and 8-SMD surface mount package. Current Transfer Ratio must fall within the allowable range (minimum 7% to 19%, maximum 50% @ 16mA). Operating temperature range must encompass the application requirements within the -55°C to 100°C envelope.

Q: Can the 6N135SMT&R replace the 6N136S(TA) in all applications?

A: The 6N135SMT&R is functionally compatible for applications where the circuit design accommodates a Current Transfer Ratio minimum of 7% @ 16mA. The original 6N136S(TA) specifies 19% minimum CTR. Circuit performance must be evaluated if the lower CTR affects output current or switching characteristics in the specific application.

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

A: Both parts provide identical Current Transfer Ratio specifications (19% minimum, 50% maximum @ 16mA). The 6N136SDVM (onsemi) operates across -40°C to 100°C with Turn On/Off times of 250ns/260ns. The 6N136SMT&R (Isocom) operates across -55°C to 100°C with Turn On/Off times of 150ns/400ns. Selection depends on temperature range requirements and switching speed priorities.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 6N136S(TA), 6N135SMT&R, 6N136SDVM, and 6N136SMT&R all carry ROHS3 Compliant status. All parts have Moisture Sensitivity Level 1 (Unlimited), confirming equivalent environmental handling requirements.

Q: What inventory levels are available for each substitute?

A: Current inventory includes 6N136S(TA) with 14,655 units, 6N135SMT&R with 1,967 units, 6N136SDVM with 1,969 units, and 6N136SMT&R with 2,188 units. All parts are listed as Active product status with new original stock.

Q: Can switching time differences affect circuit performance?

A: Switching time specifications vary across substitutes. The 6N136S(TA) specifies 350ns Turn On and 300ns Turn Off. The 6N136SDVM offers 250ns/260ns, while the 6N136SMT&R provides 150ns/400ns. Applications with timing-critical requirements must confirm that substitute switching characteristics align with circuit design specifications.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All substitute parts use 8-SMD Gull Wing surface mount packaging with Tape & Reel (TR) delivery format, matching the original 6N136S(TA) mechanical specifications for PCB assembly compatibility.
