Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6N136-X019T are classified into two categories based on parametric equivalence and manufacturer recommendation status:

Parametric Equivalents share identical or near-identical electrical and mechanical specifications with the main part:

• Same isolation voltage (5300Vrms)
• Same number of channels (1)
• Same output type (Transistor with Base)
• Same current transfer ratio minimum (19% @ 16mA)
• Same switching times (200ns typical)
• Same package format (8-SMD, Gull Wing)
• Same operating temperature range (-55°C ~ 100°C)
• Same mounting type (Surface Mount)

Manufacturer Recommended Substitutes meet functional requirements but may have variations in isolation voltage, current transfer ratio range, switching characteristics, or operating temperature range. These parts are suitable for applications where the specified parameter variations are acceptable.

The key parameters determining substitution eligibility are: isolation voltage rating, number of channels, output type, current transfer ratio, switching speed, output voltage rating, and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents (Preferred for Pin-Compatible Replacement):

The parts 6N136-X007T and 6N136-X009T are direct parametric equivalents to the 6N136-X019T. All three parts share identical electrical specifications and are manufactured by Vishay Semiconductor Opto Division. The primary difference is packaging format: 6N136-X019T is supplied in Tape & Reel (TR), while 6N136-X007T and 6N136-X009T are supplied in Cut Tape (CT) & Digi-Reel® format. These parts are suitable for direct substitution in applications where the specified packaging format is acceptable.

Manufacturer Recommended Substitutes (Functional Equivalents with Parameter Variations):

The 6N136SDVM (onsemi) and 6N136SMT&R (Isocom) maintain the same isolation voltage class (5000Vrms, compared to 5300Vrms for the main part) and identical current transfer ratio minimum (19% @ 16mA). Both are ROHS3 compliant and support the full operating temperature range of -55°C to 100°C. The 6N136SDVM exhibits slightly longer switching times (250ns/260ns versus 200ns/200ns), while 6N136SMT&R shows asymmetric switching times (150ns/400ns). These parts are suitable for applications where the 300Vrms reduction in isolation voltage is acceptable.

The 6N135SMT&R (Isocom) provides 5000Vrms isolation but has a lower current transfer ratio minimum (7% @ 16mA) and lacks specified switching time data. This part is suitable only for applications with less stringent current transfer ratio requirements.

Limited Compatibility Substitutes (Reduced Isolation Voltage):

The HCPL-4504#300 (Broadcom) and HCPL-4562-500E (Broadcom) provide only 3750Vrms isolation, representing a 1550Vrms reduction from the main part specification. The HCPL-4504#300 is not ROHS3 compliant. The HCPL-4562-500E operates at a reduced temperature range (-40°C to 85°C). These parts are suitable only for applications where lower isolation voltage is acceptable and compliance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can I use 6N136-X007T or 6N136-X009T as a direct replacement for 6N136-X019T?

A: Yes. Both parts are parametric equivalents with identical electrical specifications. The only difference is packaging format: 6N136-X019T uses Tape & Reel (TR) packaging, while 6N136-X007T and 6N136-X009T use Cut Tape (CT) & Digi-Reel® packaging. If your assembly process accepts either packaging format, these parts are fully compatible.

Q: What is the difference between the Vishay parts (6N136-X019T, 6N136-X007T, 6N136-X009T) and the Isocom/onsemi alternatives?

A: The Vishay parts provide 5300Vrms isolation, while the Isocom 6N136SMT&R and onsemi 6N136SDVM provide 5000Vrms isolation. All maintain the same 19% minimum current transfer ratio and 8-SMD package format. The Isocom 6N135SMT&R has a lower current transfer ratio minimum (7%). If your application requires the full 5300Vrms isolation specification, use only the Vishay parts.

Q: Can I substitute HCPL-4504#300 or HCPL-4562-500E for the 6N136-X019T?

A: These Broadcom parts provide only 3750Vrms isolation, which is 1550Vrms lower than the 6N136-X019T specification. Substitution is only acceptable if your application does not require the full 5300Vrms isolation rating. Additionally, HCPL-4504#300 is not ROHS3 compliant, and HCPL-4562-500E operates at a reduced temperature range (-40°C to 85°C versus -55°C to 100°C).

Q: What does "Current Transfer Ratio (CTR)" mean, and why does it matter for substitution?

A: Current Transfer Ratio is the ratio of output current to input current, expressed as a percentage at a specified input current (16mA in this case). The 6N136-X019T specifies a minimum CTR of 19%. Parts with lower CTR minimums (such as 6N135SMT&R at 7%) may not provide sufficient output current for your circuit. Parts with higher CTR minimums or ranges provide better performance margin.

Q: Are all substitute parts ROHS3 compliant?

A: No. The HCPL-4504#300 is listed as RoHS non-compliant. All other parts listed are ROHS3 compliant. If RoHS3 compliance is required for your application, do not use HCPL-4504#300.

Q: What is the difference between "Transistor" and "Transistor with Base" output types?

A: Both output types use a transistor for isolation switching. The "Transistor with Base" variant includes an accessible base connection, allowing external control of the transistor saturation characteristics. The standard "Transistor" output does not provide base access. The 6N136-X019T includes base access, as do most of its substitutes, except HCPL-4504#300 which provides standard transistor output only.

Q: Can I use parts with different operating temperature ranges?

A: The 6N136-X019T operates from -55°C to 100°C. The 6N136SDVM and HCPL-4562-500E operate from -40°C to 85°C, which is a narrower range. Substitution is acceptable only if your application does not require operation below -40°C or above 85°C.
