Key Parameters

Substitute Part Grouping Explanation

The ISP827X qualifies as a parametric equivalent to the ISP827G based on the following critical parameters that determine substitutability:

• Number of Channels: Both parts feature 2 channels
• Voltage - Isolation: Both rated at 5300Vrms
• Current Transfer Ratio: Identical specifications (50% min, 600% max @ 5mA)
• Output Type: Both are transistor output devices
• Voltage - Output (Max): Both rated at 35V
• Current - Output / Channel: Both rated at 50mA
• Package / Case: Both use 8-DIP (0.300", 7.62mm) through-hole mounting
• Operating Temperature: Both operate across -30°C ~ 100°C
• Rise / Fall Time: Both specify 4µs rise, 3µs fall time
• Vce Saturation (Max): Both rated at 200mV maximum
• Voltage - Forward (Vf) (Typ): Both specify 1.2V typical
• Current - DC Forward (If) (Max): Both rated at 50mA maximum

Both parts share the same base product number (ISP827) and are manufactured by the same supplier, confirming their functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both ISP827G and ISP827X are active products manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: ISP827G has 1177 units in stock, while ISP827X has 1416 units available. Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The through-hole 8-DIP package is suitable for standard PCB assembly processes. Both devices support the full operating temperature range of -30°C to 100°C and meet moisture sensitivity level 1 requirements.

Frequently Asked Questions (FAQ)

Q: Can ISP827X be used as a direct replacement for ISP827G?

A: Yes. Both parts share identical electrical parameters including isolation voltage (5300Vrms), channel count (2), output type (transistor), maximum output voltage (35V), and output current per channel (50mA). The physical package (8-DIP through-hole) and operating temperature range are also identical.

Q: Are there any differences in the package or mounting between ISP827G and ISP827X?

A: No. Both parts use the same 8-DIP (0.300", 7.62mm) through-hole package and mounting type. PCB layout and assembly procedures remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ISP827G and ISP827X are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: What are the key electrical parameters that define substitutability?

A: The critical parameters are isolation voltage (5300Vrms), number of channels (2), current transfer ratio range (50% to 600% @ 5mA), maximum output voltage (35V), output current per channel (50mA), and operating temperature range (-30°C to 100°C). Both parts match on all these parameters.

Q: Is there a difference in current transfer ratio performance?

A: No. Both parts specify identical current transfer ratio characteristics: minimum 50% at 5mA input current and maximum 600% at 5mA input current.
