Key Parameters

Substitute Part Grouping Explanation

The IS4N46G has one parametric equivalent within the IS4N45 series: IS4N46XG. Substitution is valid based on the following criteria:

• Identical isolation voltage rating (5300Vrms)
• Matching current transfer ratio specification (500% @ 1mA minimum)
• Identical output configuration (Darlington with Base)
• Same maximum output voltage (55V) and channel current (150mA)
• Identical saturation voltage (1.2V)
• Matching operating temperature range (-25°C ~ 100°C)
• Identical package and pinout (6-DIP, 0.400" / 10.16mm)
• Same mounting technology (Through Hole)
• Equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99)

Parameter Comparison

Engineering Selection Recommendations

Both IS4N46G and IS4N46XG are active production parts from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: IS4N46G has 775 units in stock, while IS4N46XG has 1153 units available. Both parts meet ROHS3 compliance requirements and carry equivalent regulatory classifications (REACH Unaffected, EAR99). Direct substitution is permissible in all applications where the IS4N46G is specified, provided the 6-DIP through-hole package and isolation voltage requirements are compatible with the circuit design.

Frequently Asked Questions (FAQ)

Q: Can IS4N46XG replace IS4N46G in existing designs? A: Yes. Both parts share identical electrical parameters, isolation ratings, output characteristics, and package specifications. Direct substitution is valid without circuit modification.

Q: Are there differences in isolation voltage between these parts? A: No. Both IS4N46G and IS4N46XG provide 5300Vrms isolation voltage with identical current transfer ratio performance (500% @ 1mA minimum).

Q: Do these parts have the same pinout and package dimensions? A: Yes. Both use the 6-DIP package with 0.400" (10.16mm) body width and are mounted through-hole. Pinout is identical.

Q: What is the maximum output current for these optoisolators? A: Both parts support 150mA maximum output current per channel with a single-channel Darlington configuration.

Q: Are both parts RoHS compliant? A: Yes. Both IS4N46G and IS4N46XG are ROHS3 compliant and REACH unaffected.

Q: What operating temperature range do these parts support? A: Both parts operate across -25°C to 100°C, with identical saturation voltage characteristics (1.2V maximum Vce).
