CNY75CG Equivalent & Substitute Parts

Part Overview

The CNY75CG is a single-channel optoisolator with transistor output and base connection, manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms and is designed for DC input applications requiring transistor-based output control. The part is currently in active production status with 1093 units available in stock. Alternative models become necessary when specific inventory constraints, packaging preferences, or supply chain requirements necessitate component substitution while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CNY75CG is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5300Vrms (primary isolation specification)
• Number of Channels: 1 (single-channel configuration)
• Output Type: Transistor with Base (functional output architecture)
• Current Transfer Ratio Range: 160% to 320% @ 10mA (transfer efficiency specification)
• Package Type: 6-DIP (0.400", 10.16mm) (mechanical and pin compatibility)
• Input Type: DC (signal input specification)
• Maximum Output Voltage: 90V (output rating)
• Maximum Output Current: 50mA per channel (current capacity)

The CNY75CXG meets all these criteria and is classified as a parametric equivalent. Both parts belong to the CNY75C series and share identical electrical specifications and mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both CNY75CG and CNY75CXG are active production components manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements:

• CNY75CG: 1093 units in stock. Primary selection when inventory availability is the determining factor.
• CNY75CXG: 745 units in stock. Alternative selection when CNY75CG stock is depleted or when supply chain diversification is required.

Both parts carry ROHS3 compliance and are REACH unaffected, meeting current regulatory requirements for electronic component procurement. The identical parameter sets ensure direct functional interchangeability in circuit applications without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can CNY75CXG be used as a direct replacement for CNY75CG in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, current transfer ratios, isolation voltage, output characteristics, and 6-DIP packaging. No circuit modifications are required.

Q: Are there any differences in pin configuration between CNY75CG and CNY75CXG?

A: No. Both parts use the same 6-DIP (0.400", 10.16mm) package with identical pin assignments. PCB layouts and socket compatibility are unchanged.

Q: What determines whether a part qualifies as a substitute for CNY75CG?

A: Substitution requires matching across all critical parameters: 5300Vrms isolation voltage, single-channel configuration, transistor-with-base output type, 160-320% current transfer ratio range, 90V maximum output voltage, 50mA maximum output current, DC input type, and 6-DIP package format.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CNY75CG and CNY75CXG are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain strategy. Both parts are in active production status.
