Substitute Part Grouping Explanation

Substitution eligibility for the 6N135S(TB) is determined by the following mandatory parameters:

Primary Matching Criteria:

• Voltage - Isolation: 5000Vrms (exact match required)
• Output Type: Transistor with Base (exact match required)
• Package / Case: 8-SMD, Gull Wing (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Input Type: DC (exact match required)

Secondary Compatibility Parameters:

• Voltage - Output (Max): 20V or greater
• Current - Output / Channel: 8mA or greater
• Voltage - Forward (Vf) (Typ): 1.45V
• Current - DC Forward (If) (Max): 25mA or greater

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)

The following parts meet all primary and secondary criteria for direct substitution with the 6N135S(TB):

1. 6N136SDVM (onsemi) - Similar manufacturer part with enhanced current transfer ratio performance
2. 6N136SMT&R (Isocom Components 2004 LTD) - Similar manufacturer part with improved switching speed
3. 6N135SMT&R (Isocom Components 2004 LTD) - Parametric equivalent from alternative manufacturer

Parameter Comparison

Engineering Selection Recommendations

6N136SDVM (onsemi)

This substitute provides improved current transfer ratio minimum specification (19% versus 7%) and faster turn-off time (260ns versus 500ns). The operating temperature range is -40°C to 100°C, which is narrower than the main part. This part is suitable for applications where the lower temperature limit of -40°C is acceptable and where improved current transfer characteristics provide design margin. RoHS3 compliance and unlimited MSL rating are maintained.

6N136SMT&R (Isocom Components 2004 LTD)

This substitute offers the fastest turn-on time (150ns) among all listed options while maintaining the same maximum turn-off time specification. Current transfer ratio minimum is 19%, providing improved performance over the main part. Operating temperature range matches the main part (-55°C to 100°C). RoHS3 compliance and unlimited MSL rating are maintained. Tape & Reel packaging is specified.

6N135SMT&R (Isocom Components 2004 LTD)

This parametric equivalent maintains identical current transfer ratio specifications (7% minimum, 50% maximum) as the main part. Operating temperature range matches the main part (-55°C to 100°C). Turn-on and turn-off times are not specified for this variant. RoHS3 compliance and unlimited MSL rating are maintained. Tape & Reel packaging is specified.

All three substitute parts maintain the critical 5000Vrms isolation voltage, single-channel configuration, transistor with base output type, and 8-SMD gull wing package format. Selection among substitutes depends on specific application requirements for switching speed and current transfer ratio performance.

Frequently Asked Questions (FAQ)

Q: Can 6N136SDVM be used as a direct replacement for 6N135S(TB)?

A: Yes, 6N136SDVM meets all primary matching criteria for substitution. The part maintains 5000Vrms isolation, transistor with base output, 8-SMD gull wing package, and DC input type. The operating temperature range is -40°C to 100°C, which is narrower than the original part's -55°C to 100°C range. Verify that your application does not require operation below -40°C before selection.

Q: What is the difference between 6N136SMT&R and 6N135SMT&R?

A: Both parts are manufactured by Isocom Components 2004 LTD and meet substitution criteria. The primary difference is current transfer ratio minimum specification: 6N136SMT&R specifies 19% minimum while 6N135SMT&R specifies 7% minimum. The 6N136SMT&R also provides faster turn-on time (150ns versus unspecified). Both maintain identical isolation voltage, output type, and package configuration.

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

A: The main part 6N135S(TB) packaging is not explicitly specified as Tape & Reel. The substitute parts 6N136SDVM and 6N136SMT&R are specified as Tape & Reel (TR) packaging. The 6N135SMT&R is also specified as Tape & Reel. Confirm packaging requirements for your procurement and assembly process before final selection.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes, all three substitute parts are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Compliance certifications are maintained across all options.

Q: Which substitute part offers the best switching performance?

A: The 6N136SMT&R provides the fastest turn-on time at 150ns. The 6N136SDVM provides the fastest turn-off time at 260ns. Selection depends on whether your application prioritizes input-to-output delay or output settling time.

Q: Can I use 6N136SDVM in applications requiring -55°C operation?

A: No. The 6N136SDVM operating temperature range is -40°C to 100°C. For applications requiring operation at -55°C, use either 6N136SMT&R or 6N135SMT&R, both of which specify -55°C to 100°C operating range.
