Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6N137A-X007T is determined by the following critical parameters:

• Isolation Voltage: Minimum 5000Vrms required
• Data Rate: Minimum 10MBd capability
• Number of Channels: Single channel (1 channel)
• Output Configuration: Open collector or open drain topology
• Maximum Output Current: Minimum 50 mA per channel
• Package Type: 8-SMD, Gull Wing surface mount
• Supply Voltage Compatibility: Must support 4.5V ~ 5.5V operation or broader range including this band
• RoHS Compliance: ROHS3 Compliant

The VOH260A-X007T meets these substitution criteria while offering enhanced performance characteristics in specific areas, including higher common mode transient immunity and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The VOH260A-X007T is the manufacturer-recommended substitute for the 6N137A-X007T. Both devices maintain identical isolation voltage, data rate, output current capability, and package configuration. The substitute part is currently in Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

The VOH260A-X007T provides enhanced common mode transient immunity (15kV/µs versus 1kV/µs), extended operating temperature range (-40°C ~ 110°C versus -40°C ~ 85°C), and dual supply voltage band support (2.7V ~ 3.6V and 4.5V ~ 5.5V). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

The primary design consideration is the output topology difference: the original part features open collector output while the substitute uses open drain output. This distinction requires verification of pull-up resistor configuration and load impedance in the receiving circuit to ensure functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the VOH260A-X007T directly replace the 6N137A-X007T in existing designs?

A: Direct replacement is possible when the receiving circuit accommodates open drain output topology. The open collector (6N137A-X007T) and open drain (VOH260A-X007T) configurations differ in internal transistor structure but function similarly with appropriate external pull-up resistor networks. Verify pull-up voltage and impedance compatibility with your specific application.

Q: What is the significance of the Last Time Buy status for the 6N137A-X007T?

A: Last Time Buy status indicates the manufacturer will no longer accept new orders after a specified date. Existing inventory will be depleted without replenishment. Transition to the VOH260A-X007T is recommended for new designs and long-term production planning.

Q: Are both parts suitable for the same isolation voltage applications?

A: Yes. Both the 6N137A-X007T and VOH260A-X007T provide 5000Vrms isolation voltage, meeting identical isolation requirements across industrial and medical applications.

Q: How does the common mode transient immunity difference affect substitution?

A: The VOH260A-X007T offers 15kV/µs CMTI compared to 1kV/µs for the original part. This enhanced specification provides superior noise immunity in high-speed switching environments. Applications with lower CMTI requirements will function with either part; applications requiring higher CMTI benefit from the substitute.

Q: Is the 8-SMD package identical between both parts?

A: Yes. Both parts use 8-SMD, Gull Wing surface mount packaging with identical footprint and land pattern compatibility. PCB layout modifications are not required for package accommodation.

Q: What supply voltage considerations apply when substituting?

A: The 6N137A-X007T operates at 4.5V ~ 5.5V. The VOH260A-X007T supports both 2.7V ~ 3.6V and 4.5V ~ 5.5V bands. If your design uses 5V supply, both parts are compatible. If 3.3V supply is required, only the VOH260A-X007T is suitable.
