ISP817XC Equivalent & Substitute Parts

Part Overview

The ISP817XC is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This single-channel device provides galvanic isolation rated at 5300Vrms and is housed in a 4-DIP package for through-hole mounting. The part is currently active in production with 1048 units in stock. Equivalent substitute parts are necessary when primary inventory is depleted, when alternative sourcing is required for supply chain continuity, or when design flexibility permits selection from the ISP817 series variants.

Substitute Part Grouping Explanation

The ISP817XC has three parametric equivalents within the ISP817 series: ISP817XA, ISP817XB, and ISP817XD. These parts are direct substitutes based on the following criteria:

All substitute parts share identical electrical specifications:

Isolation voltage: 5300Vrms
Current transfer ratio range: 50% to 600% @ 5mA
Output voltage maximum: 80V
Output current per channel: 50mA
Vce saturation: 200mV maximum
Rise and fall times: 4µs and 3µs respectively
Operating temperature range: -55°C to 110°C

All substitute parts share identical mechanical specifications:

Package type: 4-DIP (0.300", 7.62mm)
Mounting type: Through Hole
Input type: DC
Single channel configuration

All substitute parts maintain identical compliance and regulatory status:

RoHS3 Compliant
REACH Unaffected
ECCN: EAR99
HTSUS: 8541.49.8000
Moisture Sensitivity Level: 1 (Unlimited)

Substitution is valid across all variants because no electrical, mechanical, or functional parameters differ between the main part and substitute parts.

Engineering Selection Recommendations

All four parts—ISP817XC, ISP817XA, ISP817XB, and ISP817XD—are active products with identical electrical and mechanical specifications. Selection among these variants is based on inventory availability and supply chain requirements rather than functional differences.

ISP817XD offers the highest inventory level at 22,400 units, providing the greatest availability for high-volume applications. ISP817XA and ISP817XB maintain intermediate inventory levels of 1280 and 1225 units respectively. ISP817XC has the lowest inventory at 1048 units.

All parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Frequently Asked Questions (FAQ)

Q: Can ISP817XA, ISP817XB, and ISP817XD be used interchangeably with ISP817XC?

A: Yes. All four parts are parametric equivalents with identical electrical specifications, output characteristics, isolation voltage, current transfer ratios, and operating temperature ranges. They share the same 4-DIP package and through-hole mounting configuration.

Q: Are there any differences in isolation voltage or current ratings between these parts?

A: No. All variants maintain 5300Vrms isolation voltage, 50mA maximum output current per channel, and identical current transfer ratio specifications of 50% to 600% @ 5mA.

Q: Do all substitute parts have the same package dimensions?

A: Yes. All parts use the 4-DIP (0.300", 7.62mm) package with through-hole mounting, ensuring identical PCB layout compatibility.

Q: Which part should be selected for new designs?

A: Any of the four parts is suitable for new designs. Selection may be based on current inventory availability, supplier lead times, or established procurement preferences within your supply chain.

Q: Are there compliance or regulatory differences between the variants?

A: No. All parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.
