Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6N135S(TB)-V are classified based on strict electrical and mechanical parameter alignment. The substitution logic is determined by the following critical parameters:

Isolation Voltage: All substitute parts maintain 5000Vrms isolation, matching the primary component specification.

Channel Configuration: All alternatives provide single-channel operation identical to the main part.

Output Configuration: All substitutes feature transistor with base output topology.

Package Specification: All alternatives use 8-SMD, Gull Wing surface mount packaging, ensuring PCB compatibility.

Voltage and Current Ratings: Output voltage maximum (20V) and output current per channel (8mA) are consistent across all parts.

Operating Temperature Range: Substitute parts operate within -55°C to 100°C or -40°C to 100°C ranges, with the main part and certain substitutes supporting the full -55°C specification.

Compliance: All parts are ROHS3 compliant and carry EAR99 ECCN classification.

The 6N136SDVM and 6N136SMT&R are classified as direct substitutes with enhanced current transfer ratio minimums (19% @ 16mA versus 7% @ 16mA). The 6N135SMT&R is a parametric equivalent maintaining the original current transfer ratio specification of the main part.

Parameter Comparison

Engineering Selection Recommendations

6N136SDVM (onsemi): This part is suitable for applications where enhanced current transfer ratio performance (19% minimum) is beneficial. The onsemi device offers faster turn-on time (250ns) compared to the primary part. Operating temperature range is -40°C to 100°C, which is narrower than the main part. Selection of this substitute requires confirmation that the application does not require operation below -40°C. All compliance certifications match the primary component.

6N136SMT&R (Isocom Components 2004 LTD): This substitute provides the same enhanced current transfer ratio minimum (19%) as the onsemi alternative with the fastest turn-on time specification (150ns). The full operating temperature range (-55°C to 100°C) matches the primary part. This part is available in Tape & Reel packaging. REACH Unaffected status is documented. This substitute is suitable for direct replacement in applications requiring the full temperature range.

6N135SMT&R (Isocom Components 2004 LTD): This parametric equivalent maintains the original current transfer ratio specification (7% minimum) of the primary part. Operating temperature range is -55°C to 100°C, matching the main component. This part is available in Tape & Reel packaging. REACH Unaffected status is documented. This substitute is appropriate for applications requiring identical electrical characteristics to the original specification.

All substitute parts are Active product status with ROHS3 compliance and EAR99 ECCN classification, matching the regulatory and compliance profile of the primary component.

Frequently Asked Questions (FAQ)

Q: Can the 6N136SDVM replace the 6N135S(TB)-V in all applications?

A: The 6N136SDVM is electrically compatible for most applications due to matching isolation voltage, channel configuration, output type, and package specification. However, the operating temperature range is limited to -40°C to 100°C. Applications requiring operation below -40°C must use the primary part or the 6N136SMT&R or 6N135SMT&R alternatives.

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

A: Both parts share identical electrical specifications including 5000Vrms isolation, 19% minimum current transfer ratio, and 8-SMD Gull Wing packaging. The primary differences are manufacturer (onsemi versus Isocom), packaging format (Tape & Reel for both), and operating temperature range (6N136SDVM: -40°C to 100°C; 6N136SMT&R: -55°C to 100°C). The 6N136SMT&R supports the full temperature range of the original part.

Q: When should I use the 6N135SMT&R instead of the 6N136 variants?

A: The 6N135SMT&R maintains the original current transfer ratio specification (7% minimum @ 16mA) of the primary part. Use this substitute when the application circuit is designed for the lower current transfer ratio minimum. The 6N136 variants with 19% minimum current transfer ratio may not be suitable if the circuit requires the lower specification.

Q: Are all substitute parts available in the same packaging as the primary component?

A: All substitute parts use 8-SMD, Gull Wing surface mount packaging, ensuring PCB footprint compatibility. Packaging format variations (Tape & Reel versus other formats) do not affect electrical or mechanical compatibility on the PCB.

Q: Do all parts meet the same compliance requirements?

A: All parts are ROHS3 compliant with EAR99 ECCN classification. Moisture Sensitivity Level is 1 (Unlimited) for all parts. The 6N136SDVM, 6N136SMT&R, and 6N135SMT&R have documented REACH Unaffected status.

Q: What are the switching speed differences between the substitutes?

A: Turn-on times vary: 6N135S(TB)-V (350ns), 6N136SDVM (250ns), 6N136SMT&R (150ns). Turn-off times also differ: 6N135S(TB)-V (500ns), 6N136SDVM (260ns), 6N136SMT&R (400ns). Applications with timing-critical circuits should account for these variations.
