Key Parameters

Substitute Part Grouping Explanation

The WL-OCDA series optoisolators 141815142000, 141815143000, and 141815144000 are parametric equivalents based on the following criteria:

Identical Electrical Parameters:

• Voltage isolation: 5000Vrms
• Number of channels: 1
• Output type: Darlington
• Current transfer ratio: 600% to 7500% @ 1mA
• Maximum output voltage: 40V
• Maximum output current per channel: 80mA
• Vce saturation: 1V maximum
• Operating temperature range: -55°C to 110°C
• Input type: DC
• Rise/Fall time: 95µs, 84µs

Differentiation Factor: The three parts differ only in their supplier device package designation, which reflects variations in lead frame and tape reel specifications while maintaining identical electrical performance and mechanical compatibility for surface mount assembly.

Parameter Comparison

Engineering Selection Recommendations

All three parts within the WL-OCDA series maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between 141815142000, 141815143000, and 141815144000 is determined by packaging and supply chain requirements rather than electrical performance.

The 141815142000 (4-DIP-S package) is suitable for standard surface mount applications. The 141815143000 (4-DIP-SL package) and 141815144000 (4-DIP-SLM package) provide alternative packaging configurations for specific manufacturing or inventory requirements.

All parts are manufactured by Würth Elektronik and carry identical electrical specifications, operating temperature ranges, and regulatory compliance certifications. Component selection should be based on available inventory, tape reel specifications, and manufacturing process compatibility.

Frequently Asked Questions (FAQ)

Q: Can 141815143000 be used as a direct replacement for 141815142000?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, isolation voltage, output current capability, and operating temperature range. The difference is limited to the supplier device package designation (4-DIP-SL versus 4-DIP-S), which relates to tape reel and lead frame specifications.

Q: What is the difference between the 4-DIP-S, 4-DIP-SL, and 4-DIP-SLM packages designations?

A: These designations indicate variations in the supplier device package configuration, including lead frame geometry and tape reel specifications. All three maintain identical 4-SMD Gull Wing mechanical compatibility for surface mount assembly and identical electrical performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts (141815142000, 141815143000, and 141815144000) are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the maximum isolation voltage for these optoisolators?

A: The maximum isolation voltage is 5000Vrms for all three parts in the WL-OCDA series.

Q: Can these parts operate at temperatures below -55°C or above 110°C?

A: No. The specified operating temperature range for all three parts is -55°C to 110°C. Operation outside this range is not supported.

Q: What is the current transfer ratio specification?

A: The current transfer ratio ranges from 600% minimum to 7500% maximum, measured at 1mA input current, for all three equivalent parts.

Q: Are these parts suitable for high-speed switching applications?

A: The rise and fall times are specified as 95µs and 84µs respectively. These timing characteristics apply uniformly across all three equivalent parts.
