Engineering Selection Recommendations
Direct Replacement (Identical Electrical Specifications): CNY117-4, CNY117-4X001, and CNY17-4X001 are parametric equivalents manufactured by Vishay Semiconductor Opto Division with Active product status. These parts maintain identical current transfer ratio, output current, saturation voltage, and operating temperature range. All three are ROHS3 compliant and REACH unaffected.
Enhanced Performance Alternative: CNY17-4 from Lite-On Inc. provides higher output current capability (150mA vs 50mA) and lower saturation voltage (300mV vs 400mV) while maintaining the same 160% to 320% current transfer ratio. This part is Active status and suitable for new designs. The trade-off is slightly slower rise/fall time (5µs vs 2µs) and reduced maximum operating temperature (100°C vs 110°C).
Lower Current Transfer Ratio Variants: CNY17-1 series parts (Lite-On Inc., Broadcom Limited variants) operate with 40% to 80% current transfer ratio, representing reduced optical coupling efficiency. These are suitable only when circuit design accommodates lower CTR specifications. All variants are Active status and ROHS3 compliant.
Package Consideration: CNY17-1-W00E uses 0.400" DIP spacing versus the standard 0.300" spacing of CNY17-4. This variant is mechanically incompatible with standard 0.300" DIP footprints.
Frequently Asked Questions (FAQ)
Q: Can CNY17-4 be replaced with CNY17-1? A: Only if circuit design accommodates the reduced current transfer ratio of 40% to 80% @ 10mA versus the CNY17-4 specification of 160% to 320% @ 10mA. The lower CTR affects optical coupling efficiency and may require circuit redesign.
Q: What is the difference between CNY117-4 and CNY17-4? A: CNY117-4 and CNY17-4X001 are parametric equivalents to the original CNY17-4 with identical electrical performance. The CNY117 designation represents a product line variant from Vishay. Both maintain 160% to 320% CTR, 50mA output current, and -55°C to 110°C operating range.
Q: Is the Lite-On CNY17-4 a direct replacement? A: The Lite-On CNY17-4 maintains the same 160% to 320% current transfer ratio and 5000Vrms isolation voltage. However, it provides higher output current (150mA vs 50mA) and lower saturation voltage (300mV vs 400mV). The operating temperature maximum is reduced to 100°C. Verify circuit requirements before substitution.
Q: Why does CNY17-1-W00E have different DIP spacing? A: CNY17-1-W00E uses 0.400" (10.16mm) DIP spacing versus the standard 0.300" (7.62mm) spacing. This variant is not mechanically compatible with standard 0.300" DIP sockets or PCB footprints.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original CNY17-4 certification.
Q: What is the inventory status of active alternatives? A: CNY17-4 (Lite-On Inc.) has 89,800 pcs in stock. CNY117-4 has 7,754 pcs. CNY17-1 variants from Lite-On and Broadcom have 48,700 and 4,250 to 20,900 pcs respectively. CNY17-4X001 and CNY117-4X001 have lower inventory at 827 and 1,850 pcs.
