Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CNY17-3-V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor with Base (mandatory match)
• Package / Case: 6-DIP (0.300", 7.62mm) (mandatory match)
• Mounting Type: Through Hole (mandatory match)
• Input Type: DC (mandatory match)

Secondary Performance Parameters:

• Current Transfer Ratio range compatibility
• Turn On / Turn Off Time specifications
• Rise / Fall Time characteristics
• Voltage - Output (Max) rating
• Vce Saturation (Max) rating
• Operating Temperature range
• Forward voltage characteristics

All identified substitute parts maintain the mandatory primary compatibility criteria. Variations in secondary performance parameters reflect different manufacturer specifications within the CNY17 optoisolator family.

Parameter Comparison

Engineering Selection Recommendations

CNY17-1 (Lite-On Inc.)

The CNY17-1 maintains full compatibility with the CNY17-3-V across all mandatory parameters. This substitute features a lower current transfer ratio range (40-80% @ 10mA) compared to the CNY17-3-V (100-200% @ 10mA), resulting in different input current requirements for equivalent output performance. The CNY17-1 supports 150mA output current and operates across -55°C to 100°C. All regulatory certifications match the primary part. High inventory availability (48700 pieces) supports supply chain continuity.

CNY17-1X001 (Vishay Semiconductor Opto Division)

The CNY17-1X001 provides full compatibility with mandatory parameters and extends the operating temperature range to 110°C, matching the CNY17-3-V upper limit. This part features the fastest switching characteristics (3µs turn-on, 2.3µs turn-off) and rise/fall times (2µs each) among all substitutes. Output current is limited to 50mA. Vce saturation is specified at 400mV, 100mV higher than the primary part. REACH compliance is documented. Moderate inventory availability (3108 pieces) supports standard procurement.

CNY17-3 (Quality Technologies)

The CNY17-3 maintains mandatory compatibility parameters with packaging specified as Box rather than Tube. Limited technical specifications are provided for this part. Current transfer ratio maximum is specified at 100% @ 10mA. Highest inventory availability (94700 pieces) among all substitutes. All regulatory certifications are current.

CNY17-4 (Lite-On Inc.)

The CNY17-4 maintains full compatibility with mandatory parameters and features the highest current transfer ratio range (160-320% @ 10mA) among all substitutes. This characteristic requires lower input current for equivalent output performance. The CNY17-4 supports 150mA output current and operates across -55°C to 100°C. All regulatory certifications match the primary part. High inventory availability (89800 pieces) supports supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: What are the mandatory compatibility requirements for substituting the CNY17-3-V?

A: Substitute parts must maintain the following parameters: 5000Vrms isolation voltage, single channel configuration, transistor with base output type, 6-DIP through-hole package, and DC input type. All identified substitutes meet these requirements.

Q: How do current transfer ratio differences affect circuit design?

A: Current transfer ratio determines the relationship between input LED current and output transistor current. The CNY17-3-V specifies 100-200% @ 10mA, while substitutes range from 40-320% @ 10mA. Lower ratios require higher input current for equivalent output; higher ratios require lower input current. Circuit input current calculations must be adjusted accordingly.

Q: Are there temperature range limitations when substituting?

A: The CNY17-3-V operates from -55°C to 110°C. The CNY17-1 and CNY17-4 (Lite-On) are limited to -55°C to 100°C. The CNY17-1X001 (Vishay) matches the full -55°C to 110°C range. Applications requiring operation above 100°C must use the CNY17-3-V or CNY17-1X001.

Q: What is the significance of switching time differences?

A: Turn-on/turn-off times and rise/fall times affect circuit response speed. The CNY17-1X001 provides the fastest switching (3µs turn-on, 2.3µs turn-off, 2µs rise/fall). The CNY17-3-V specifies 10µs turn-on and 9µs turn-off. Applications with strict timing requirements must verify switching characteristics against circuit specifications.

Q: Can the CNY17-3-V be replaced with CNY17-3 from Quality Technologies?

A: The CNY17-3 maintains mandatory compatibility parameters. However, limited technical specifications are provided for this part, including isolation voltage, switching times, and output current ratings. Verification against application requirements is necessary before substitution.

Q: What is the difference between Tube and Box packaging?

A: Tube packaging is standard for component reels used in automated assembly. Box packaging typically indicates alternative packaging for manual assembly or special handling. The CNY17-3 (Quality Technologies) is specified with Box packaging; all other substitutes use Tube packaging. Procurement and assembly processes may require adjustment.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitutes, including the primary CNY17-3-V, are ROHS3 compliant. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special moisture handling requirements during storage or assembly.

Q: Which substitute offers the best inventory availability?

A: The CNY17-3 (Quality Technologies) provides the highest inventory availability at 94700 pieces. The CNY17-4 (Lite-On) offers 89800 pieces, and the CNY17-1 (Lite-On) provides 48700 pieces. The CNY17-1X001 (Vishay) has the lowest availability at 3108 pieces.
