Parameter Comparison

Engineering Selection Recommendations

6N135SMT&R (Isocom Components 2004 LTD): This substitute maintains full electrical compatibility with the 6N136S(TB)-V across all critical parameters. The Current Transfer Ratio minimum of 7% is lower than the primary part's 19%, representing the only electrical variance. This part is Active status, ROHS3 compliant, and MSL 1 rated. Selection is appropriate for applications where the lower CTR minimum does not impose circuit performance constraints. Inventory availability is 1967 units.

6N136SDVM (onsemi): This substitute provides parametric equivalence with identical Current Transfer Ratio specifications (19% min, 50% max). The onsemi variant exhibits faster turn-on time (250ns vs. 350ns) and comparable turn-off time (260ns vs. 300ns). Operating temperature minimum is -40°C, which is 15°C higher than the primary part. This part is Active status, ROHS3 compliant, REACH Unaffected, and MSL 1 rated. Selection is appropriate for applications operating within the -40°C to 100°C range. Inventory availability is 1969 units.

6N136SMT&R (Isocom Components 2004 LTD): This substitute provides full parametric equivalence with identical Current Transfer Ratio specifications (19% min, 50% max) and operating temperature range (-55°C to 100°C). Turn-on time is faster (150ns vs. 350ns) while turn-off time is slower (400ns vs. 300ns). This part is Active status, ROHS3 compliant, REACH Unaffected, and MSL 1 rated. Selection is appropriate for applications where faster input response is beneficial. Inventory availability is 2188 units.

Frequently Asked Questions (FAQ)

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

A: The 6N135SMT&R is electrically compatible with the 6N136S(TB)-V across all mandatory parameters including isolation voltage, channel count, output type, and package configuration. The Current Transfer Ratio minimum specification is 7% compared to 19% for the primary part. Direct substitution is permissible provided the application circuit design accommodates the lower CTR minimum value.

Q: What is the primary difference between the onsemi 6N136SDVM and the Everlight 6N136S(TB)-V?

A: The 6N136SDVM maintains identical Current Transfer Ratio specifications and output characteristics. The primary difference is the operating temperature minimum of -40°C versus -55°C for the primary part. The onsemi variant also exhibits faster switching times (250ns turn-on vs. 350ns). Selection depends on whether the application requires operation below -40°C.

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

A: All substitute parts listed are supplied in 8-SMD, Gull Wing surface mount packages with Tape & Reel (TR) packaging. PCB footprint and reflow soldering parameters are identical across all variants.

Q: Do all substitute parts meet RoHS compliance requirements?

A: All substitute parts listed are ROHS3 compliant. The 6N136SDVM and 6N136SMT&R are additionally REACH Unaffected. Compliance documentation is available from respective manufacturers.

Q: What is the significance of the MSL 1 (Unlimited) rating across all parts?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and do not require moisture bake-out procedures prior to assembly. This classification applies uniformly to the primary part and all substitutes.

Q: How do switching times affect circuit performance in substitution scenarios?

A: Turn-on and turn-off times determine the optoisolator response speed to input signal transitions. The 6N136SMT&R offers the fastest turn-on (150ns) while the 6N136SDVM provides intermediate speed (250ns). The primary part specifies 350ns turn-on. Selection should align with circuit timing requirements and signal frequency specifications.

Q: Is the lower Current Transfer Ratio minimum of the 6N135SMT&R a limiting factor?

A: The 6N135SMT&R specifies a 7% CTR minimum compared to 19% for other variants. This affects the output current magnitude for a given input current. Circuit designs must verify that the lower CTR minimum does not reduce output current below required thresholds for proper circuit operation.
