MOC217R1VM Equivalent & Substitute Parts

Part Overview

The MOC217R1VM is an optoisolator transistor with base output rated for 2500Vrms isolation voltage in an 8-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement. The MOC217R1VM provides galvanic isolation with a single transistor output channel suitable for DC input applications requiring 150mA output current capability.

Substitute Part Grouping Explanation

Substitute parts for the MOC217R1VM are classified into two categories based on electrical parameter alignment:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: 2500Vrms isolation voltage, 100% current transfer ratio at 10mA, 150mA output current, 30V maximum output voltage, identical switching times (7.5µs turn-on, 5.7µs turn-off), and 8-SOIC package compatibility. These parts differ only in product status (active vs. obsolete) and packaging format (tape & reel or bulk).

Similar Parts share the same 8-SOIC package footprint and transistor output configuration but operate at higher isolation voltage (4000Vrms) with different current transfer ratio specifications. These parts are suitable when higher isolation voltage is acceptable or required by system design.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

MOC217R2M and MOC217R2VM are parametric equivalents to the MOC217R1VM with active product status. Both maintain identical electrical performance across isolation voltage, current transfer ratio, switching characteristics, and output specifications. MOC217R2M is supplied in tape & reel packaging and carries RoHS3 compliance certification. MOC217R2VM is supplied in bulk packaging. Both parts are suitable for direct substitution in designs currently using the obsolete MOC217R1VM.

For Higher Isolation Voltage Applications:

IL215AT and IL216AT are active optoisolators from Vishay Semiconductor Opto Division rated for 4000Vrms isolation voltage. These parts maintain the same 8-SOIC package footprint and transistor output configuration. IL215AT specifies 20% current transfer ratio at 1mA, while IL216AT specifies 50% current transfer ratio at 1mA. Both parts feature faster switching times (3µs turn-on and turn-off) and extended operating temperature range (-55°C to 100°C). These parts are suitable for applications where higher isolation voltage is required or where improved temperature performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can MOC217R2M or MOC217R2VM be used as direct replacements for MOC217R1VM?

A: Yes. MOC217R2M and MOC217R2VM are parametric equivalents with identical electrical specifications including 2500Vrms isolation voltage, 100% current transfer ratio at 10mA, 150mA output current capability, and 30V maximum output voltage. The primary differences are product status (active vs. obsolete) and packaging format. Both are suitable for direct substitution.

Q: What are the key differences between MOC217R2M and MOC217R2VM?

A: Both parts are parametric equivalents with identical electrical performance. MOC217R2M is supplied in tape & reel packaging and carries RoHS3 compliance certification. MOC217R2VM is supplied in bulk packaging. Selection depends on procurement requirements and packaging preferences.

Q: When should IL215AT or IL216AT be used instead of MOC217R2M/MOC217R2VM?

A: IL215AT and IL216AT operate at 4000Vrms isolation voltage compared to 2500Vrms for the MOC217 series. These parts are suitable when system design requires higher isolation voltage or when extended temperature range (-55°C to 100°C) is necessary.
