Substitute Part Grouping Explanation

Substitute parts for the ISP825X-3 are identified based on strict equivalence across the following critical parameters:

  • Isolation Voltage: 5300Vrms (primary isolation specification)
  • Channel Configuration: 2 channels (functional requirement)
  • Output Type: Darlington (output stage topology)
  • Package Type: 8-DIP through-hole (mechanical and electrical interface)
  • Input Type: DC (signal input specification)
  • Current Transfer Ratio Range: 600% to 7500% @ 1mA (transfer characteristic)
  • Maximum Output Voltage: 35V (output rating)
  • Maximum Output Current per Channel: 80mA (current capacity)
  • Operating Temperature Range: -30°C ~ 100°C (thermal specification)
  • Compliance Standards: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The ISP825X (without the "-3" suffix) meets all these criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

Both the ISP825X-3 and ISP825X are active production components from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

The ISP825X-3 currently maintains 745 units in stock inventory. The ISP825X substitute maintains 884 units in stock inventory, providing an alternative source when primary part availability is constrained.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The through-hole 8-DIP package ensures direct mechanical and electrical compatibility in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ISP825X be used as a direct replacement for ISP825X-3?

A: Yes. The ISP825X meets all electrical and mechanical specifications of the ISP825X-3. Both components provide identical isolation voltage (5300Vrms), dual-channel Darlington output configuration, current transfer ratio range (600% to 7500% @ 1mA), output voltage rating (35V maximum), output current capacity (80mA per channel), and operating temperature range (-30°C to 100°C). Package type, mounting method, and compliance certifications are identical.

Q: Are there any differences in the part numbers that affect compatibility?

A: The ISP825X-3 and ISP825X differ only in the suffix designation. This suffix does not reflect differences in electrical performance, isolation rating, channel count, output type, or package configuration. Both parts are manufactured by Isocom Components 2004 LTD and share the same base product number (ISP825).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: isolation voltage (5300Vrms), number of channels (2), output type (Darlington), package type (8-DIP through-hole), current transfer ratio range (600% to 7500% @ 1mA), maximum output voltage (35V), maximum output current per channel (80mA), and operating temperature range (-30°C to 100°C).

Q: Do both parts have the same compliance certifications?

A: Yes. Both ISP825X-3 and ISP825X are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for component selection in regulated industries.

Q: Is there a difference in packaging or shipping format?

A: Both parts are supplied in tube packaging. Inventory availability differs: ISP825X-3 has 745 units in stock, while ISP825X has 884 units in stock.
