Key Parameters

Substitute Part Grouping Explanation

Substitution for the PC957L0YIP0F is determined by the following critical parameters:

• Isolation voltage rating of 5000Vrms or higher
• Single-channel configuration
• Transistor output topology
• DC input type
• 8-SMD surface mount package
• Current transfer ratio minimum of 19% @ 16mA
• Output current capability of 8mA per channel
• Operating temperature range encompassing -55°C to 85°C
• Moisture sensitivity level MSL 1

The substitute part 6N136-X017T from Vishay Semiconductor Opto Division meets these criteria with an isolation voltage of 5300Vrms, matching current transfer ratio specifications, compatible output current rating, and equivalent surface mount packaging. The 6N136-X017T features transistor output with base connection, providing enhanced design flexibility while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 6N136-X017T is the qualified substitute for PC957L0YIP0F applications. Selection is based on the following factors:

The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. The 6N136-X017T exceeds the isolation voltage requirement with 5300Vrms versus the original 5000Vrms specification. Current transfer ratio specifications are identical at 19% minimum @ 16mA, ensuring equivalent signal transfer characteristics. Output current capability matches at 8mA per channel.

The 6N136-X017T features transistor output with base connection, providing additional design flexibility compared to the standard transistor output of the original part. The extended operating temperature range of -55°C to 100°C encompasses the original -55°C to 85°C specification. Both parts maintain MSL 1 moisture sensitivity rating and equivalent surface mount packaging.

The 6N136-X017T is RoHS3 compliant, meeting current environmental and regulatory requirements. Turn-on time remains at 200ns; turn-off time improves to 200ns from the original 400ns specification.

Frequently Asked Questions (FAQ)

Q: Can the 6N136-X017T directly replace the PC957L0YIP0F in existing designs?

A: The 6N136-X017T is functionally compatible as a substitute. Both parts share identical channel count, current transfer ratio specifications, output current rating, and 8-SMD surface mount packaging. The substitute features higher isolation voltage (5300Vrms vs 5000Vrms) and improved turn-off time (200ns vs 400ns). The base connection on the 6N136-X017T output transistor provides additional design flexibility. Verify that the 15V maximum output voltage of the substitute meets your application requirements, as it is lower than the original 20V specification.

Q: What are the key differences between these parts?

A: The primary differences are: (1) Product status—the original is obsolete while the substitute is active; (2) Output type—the substitute includes a base connection on the transistor output; (3) Maximum output voltage—15V for the substitute versus 20V for the original; (4) Turn-off time—200ns for the substitute versus 400ns for the original; (5) Operating temperature range—the substitute extends to 100°C versus 85°C for the original.

Q: Are there any packaging considerations when switching to the 6N136-X017T?

A: Both parts use 8-SMD surface mount packaging with identical pin configurations. The 6N136-X017T is specified as 8-SMD Gull Wing, which is compatible with standard surface mount assembly processes. No PCB layout modifications are required for package compatibility.

Q: What compliance certifications apply to the substitute part?

A: The 6N136-X017T is RoHS3 compliant, meeting current environmental regulations. Both the original and substitute parts carry ECCN EAR99 and HTSUS 8541.49.8000 classifications.

Q: How do the electrical specifications compare for signal integrity?

A: Current transfer ratio specifications are identical at 19% minimum @ 16mA, ensuring equivalent signal transfer performance. The substitute's improved turn-off time of 200ns (versus 400ns) provides faster switching response. Input and output types remain DC-to-transistor configuration. Forward voltage differs slightly (1.33V for substitute versus 1.7V for original), which may affect input circuit design but does not impact isolation or output functionality.
