Key Parameters

Substitute Part Grouping Explanation

Substitution within the CNY17 family is determined by the following criteria:

Fixed Parameters (Must Match):

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Output type: Transistor with Base
• Package / Case: 6-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Input type: DC
• RoHS3 compliance

Variable Parameters (Differentiate Substitutes):

• Current Transfer Ratio (CTR) at 10mA: Ranges from 40%-320% depending on grade
• Maximum output voltage: 70V-80V
• Output current per channel: 150mA or unspecified
• Forward voltage (Vf): 1.4V-1.65V
• Operating temperature maximum: 100°C-110°C
• Turn-on/turn-off time specifications

The CNY17-3 is characterized by 100%-200% CTR at 10mA. Broadcom Limited manufactures equivalent variants (CNY17-1-000E, CNY17-2-000E, CNY17-3-000E, CNY17-4-000E) with different CTR grades and output voltage ratings, all maintaining the same 5000Vrms isolation and 6-DIP package configuration.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent: CNY17-3-000E (Broadcom Limited) is the direct equivalent to CNY17-3 (Everlight Electronics Co Ltd). Both parts share identical CTR specifications (100%-200% @ 10mA) and are RoHS3 compliant with MSL 1 rating. The Broadcom variant is available in Tube packaging with 9,859 units in stock.

Grade-Based Alternatives:

• CNY17-1-000E: Lower CTR grade (40%-80% @ 10mA). Use when lower current transfer is acceptable and cost optimization is required.
• CNY17-2-000E: Mid-range CTR grade (63%-125% @ 10mA). Use for applications requiring moderate current transfer characteristics.
• CNY17-4-000E: Higher CTR grade (160%-320% @ 10mA). Use when maximum current transfer and faster response are required.

All substitute parts maintain 5000Vrms isolation voltage, 6-DIP through-hole package, and RoHS3 compliance. All are Active status products. Operating temperature maximum for Broadcom variants is -55°C to 100°C, compared to -55°C to 110°C for the Everlight CNY17-3.

Frequently Asked Questions (FAQ)

Q: Can CNY17-3-000E directly replace CNY17-3? A: Yes. Both parts have identical Current Transfer Ratio specifications (100%-200% @ 10mA), matching isolation voltage (5000Vrms), identical package configuration (6-DIP through-hole), and equivalent compliance ratings (RoHS3, MSL 1). The primary difference is manufacturer (Broadcom vs. Everlight) and packaging format (Tube vs. unspecified).

Q: What is the difference between CNY17-1-000E, CNY17-2-000E, CNY17-3-000E, and CNY17-4-000E? A: These variants differ in Current Transfer Ratio grades at 10mA input current. CNY17-1-000E provides 40%-80% CTR, CNY17-2-000E provides 63%-125% CTR, CNY17-3-000E provides 100%-200% CTR, and CNY17-4-000E provides 160%-320% CTR. All other electrical and mechanical parameters remain constant across the family.

Q: Are there package differences between substitute parts? A: All substitute parts use the same 6-DIP (0.300", 7.62mm) through-hole package. The CNY17-3 (Everlight) packaging is unspecified, while Broadcom variants are supplied in Tube packaging. Both formats are compatible with standard through-hole PCB assembly processes.

Q: What is the maximum output voltage difference? A: The CNY17-3 (Everlight) has a maximum output voltage of 80V, while all Broadcom variants (CNY17-1-000E through CNY17-4-000E) have a maximum output voltage of 70V. Applications requiring output voltages above 70V must use the Everlight CNY17-3.

Q: Do all parts support the same operating temperature range? A: No. The CNY17-3 (Everlight) operates from -55°C to 110°C, while all Broadcom variants operate from -55°C to 100°C. Applications requiring operation above 100°C must use the Everlight CNY17-3.

Q: Are timing specifications available for all parts? A: The CNY17-3 (Everlight) provides turn-on/turn-off times (10µs/9µs typical) and rise/fall times (6µs/8µs typical). Broadcom variants provide only rise/fall time specifications (5µs/5µs typical). Turn-on/turn-off time data is not available for Broadcom parts.

Q: What is the current output capability per channel? A: The CNY17-3 (Everlight) does not specify maximum output current per channel. All Broadcom variants specify 150mA maximum output current per channel.
