MID400SV Equivalent & Substitute Parts

Part Overview

The MID400SV is an optoisolator AC line monitor manufactured by onsemi, designed for applications requiring galvanic isolation up to 2500Vrms with a single channel configuration. This component integrates an LED input stage with an open collector output, suitable for AC and DC input monitoring in industrial and power management applications.

The MID400SV carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MID400SV is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 2500Vrms
• Channel configuration: Single channel
• Input capability: AC and DC compatible
• Output current specification: 20mA per channel
• Propagation delay characteristics: 1ms maximum
• Package form factor: 8-SMD, Gull Wing surface mount
• Electrical characteristics: Forward voltage 1.5V typical, 30mA maximum forward current
• Supply voltage: 7V
• Temperature operating range: -40°C to 85°C
• Regulatory compliance: UR and VDE approval

The MID400SVM qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MID400SVM is the direct substitute for the MID400SV. Both components share identical electrical specifications, isolation ratings, channel configuration, and regulatory certifications (UR, VDE approval). Both maintain ROHS3 compliance and REACH unaffected status.

The primary advantage of selecting MID400SVM is its active product status, ensuring ongoing availability and manufacturing support. The MID400SV, classified as obsolete, presents supply chain risk for new production or long-term inventory requirements.

Packaging format differs between the two parts: MID400SV is supplied in tape and reel format, while MID400SVM is supplied in tube format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MID400SVM be used as a direct replacement for MID400SV in existing designs?

A: Yes. The MID400SVM provides identical electrical performance, isolation voltage, channel configuration, output current, propagation delay, and operating temperature range. Both components use the same 8-SMD, Gull Wing package and meet UR and VDE regulatory requirements.

Q: What is the difference between the two parts?

A: The MID400SV is obsolete, while MID400SVM is active. MID400SV is supplied in tape and reel packaging; MID400SVM is supplied in tube packaging. Electrical specifications and performance characteristics are identical.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (tape and reel versus tube) affects only handling, storage, and assembly logistics. Electrical performance and functional characteristics remain unchanged.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both MID400SV and MID400SVM are ROHS3 compliant, REACH unaffected, and carry UR and VDE approvals.

Q: Which part should be selected for new designs?

A: MID400SVM should be selected for new designs due to its active product status and assured long-term availability.
