ISP847XD Equivalent & Substitute Parts

Part Overview

The ISP847XD is a quad-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin DIP component provides galvanic isolation up to 5300Vrms across four independent channels, each capable of 50mA output current. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when identical electrical specifications, mechanical packaging, and compliance certifications are maintained across the ISP847 series.

Substitute Part Grouping Explanation

Substitute parts for the ISP847XD are identified within the ISP847 series based on strict parametric equivalence. The following electrical and mechanical parameters must remain identical for substitution validity:

• Voltage isolation rating: 5300Vrms
• Number of channels: 4
• Current transfer ratio range: 300% to 600% @ 5mA
• Output type: Transistor
• Maximum output voltage: 35V
• Output current per channel: 50mA
• Vce saturation: 200mV maximum
• Rise/fall time: 4µs and 3µs
• Operating temperature range: -30°C to 100°C
• Package type: 16-DIP (0.300", 7.62mm)
• Mounting: Through Hole
• Compliance: RoHS3 Compliant, REACH Unaffected

All substitute parts maintain identical specifications across these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ISP847XD, ISP847XDG, and ISP847XDSM—are functionally equivalent optoisolators within the ISP847 series. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

Current inventory levels are as follows: ISP847XD (1087 pcs), ISP847XDG (736 pcs), and ISP847XDSM (757 pcs). All parts maintain Active product status with identical RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance across all three options.

For applications requiring galvanic isolation in industrial control, power management, or signal conditioning circuits, any of these three part numbers provide equivalent electrical performance and mechanical compatibility. PCB layout and component placement remain unchanged when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can ISP847XDG be used as a direct replacement for ISP847XD?

A: Yes. ISP847XDG maintains identical electrical specifications, isolation voltage, output current rating, and 16-DIP package configuration. No circuit modifications are required.

Q: Are there differences in isolation voltage between ISP847XD and ISP847XDSM?

A: No. Both parts provide 5300Vrms isolation rating. All electrical parameters remain identical across the ISP847 series variants.

Q: What is the significance of the different part number suffixes (XD, XDG, XDSM)?

A: The suffixes indicate manufacturing or packaging variants within the ISP847 series. All variants maintain identical electrical and mechanical specifications as defined in this reference.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts use the 16-DIP (0.300", 7.62mm) through-hole package with identical pin configuration and electrical characteristics. No PCB redesign is necessary.

Q: Are all three parts RoHS3 compliant?

A: Yes. ISP847XD, ISP847XDG, and ISP847XDSM are all RoHS3 compliant with REACH unaffected status.

Q: What is the maximum output current per channel?

A: Each of the four channels supports a maximum output current of 50mA at 35V maximum output voltage.

Q: What operating temperature range applies to all variants?

A: All three parts operate across -30°C to 100°C temperature range.
