Engineering Selection Recommendations

Primary Selection: ELW136

The ELW136 is the primary component specification with Active product status and 1113 units in current inventory. This part maintains full ROHS3 compliance and Moisture Sensitivity Level 1 rating, supporting unlimited shelf life storage conditions.

Substitute Selection: 6N136G

The 6N136G qualifies as a direct parametric substitute with equivalent electrical performance across all specified parameters. This component is manufactured by Isocom Components 2004 LTD and maintains Active product status with 1042 units in inventory. The 6N136G is ROHS3 compliant with identical Moisture Sensitivity Level 1 classification and REACH Unaffected status.

Both components support identical circuit implementations without modification to PCB layout, component footprint, or electrical interface design. Selection between these parts is determined by availability, supply chain logistics, and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 6N136G replace the ELW136 in existing circuit designs?

A: Yes. The 6N136G provides electrical and mechanical equivalence across all specified parameters. Both components feature identical isolation voltage (5000Vrms), output configuration (transistor with base), current transfer ratio range (19-50% @ 16mA), and 8-DIP through-hole package format. No circuit modifications are required.

Q: Are there differences in switching speed between the ELW136 and 6N136G?

A: The ELW136 specifies turn-on and turn-off times of 320ns and 250ns respectively. The 6N136G does not provide specified turn-on/turn-off time values in the available data. Applications with critical timing requirements should reference detailed manufacturer datasheets for switching performance verification.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the ELW136 and 6N136G are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) classification. Both carry EAR99 ECCN designation and HTSUS code 8541.49.8000. The 6N136G additionally carries REACH Unaffected status.

Q: What is the maximum operating temperature for these optoisolators?

A: Both the ELW136 and 6N136G operate across the temperature range of -55°C to 100°C. This range supports industrial and commercial applications with standard thermal management.

Q: Are these components suitable for high-speed digital isolation applications?

A: Both components feature DC input type and transistor with base output configuration. The ELW136 specifies switching times of 320ns turn-on and 250ns turn-off. Applications requiring high-speed digital isolation should evaluate these timing specifications against circuit requirements.

Q: What is the current transfer ratio specification, and how does it affect circuit design?

A: Both parts specify a current transfer ratio range of 19% to 50% at 16mA input current. This parameter defines the ratio of output current to input current and directly affects LED drive current requirements and output transistor saturation characteristics. Circuit design must account for the minimum 19% ratio to ensure reliable operation across component tolerance ranges.

Q: Can these optoisolators be used in applications requiring 5000Vrms isolation?

A: Yes. Both the ELW136 and 6N136G are rated for 5000Vrms isolation voltage, supporting high-voltage isolation requirements in industrial power conversion, motor control, and utility applications.

Q: What is the maximum output current per channel?

A: Both components provide 8mA maximum output current per channel with a maximum output voltage rating of 20V. Circuit design must ensure load impedance and external pull-up resistor values do not exceed these specifications.
