Substitute Part Grouping Explanation

Substitute parts for the ISP847BSM are identified within the ISP847 series based on strict parametric equivalence. The following electrical and mechanical parameters must remain identical for substitution validity:

• Number of Channels: 4
• Voltage - Isolation: 5300Vrms
• Current Transfer Ratio (Min/Max): 130% / 260% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 35V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Rise / Fall Time (Typ): 4µs, 3µs
• Operating Temperature: -30°C ~ 100°C
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts maintain identical performance specifications and are manufactured by the same supplier, ensuring direct functional replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—ISP847XB, ISP847XBG, and ISP847XBSM—are functionally equivalent to the ISP847BSM and maintain Active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. Selection among these equivalents may be based on inventory availability and packaging preferences, as all electrical and mechanical specifications are identical. The ISP847XBSM variant currently maintains the highest inventory level at 1098 pieces, followed by ISP847XB at 956 pieces and ISP847XBG at 707 pieces.

Frequently Asked Questions (FAQ)

Q: Can ISP847XB, ISP847XBG, and ISP847XBSM be used interchangeably with ISP847BSM?

A: Yes. All parts share identical electrical specifications including isolation voltage, current transfer ratio, output voltage, output current, and switching characteristics. The 16-DIP through-hole package is consistent across all variants, enabling direct socket substitution without circuit modification.

Q: What determines substitution eligibility for ISP847 series optoisolators?

A: Substitution is valid when the following parameters remain constant: number of channels (4), isolation voltage (5300Vrms), current transfer ratio range (130–260% @ 5mA), output type (transistor), maximum output voltage (35V), maximum output current per channel (50mA), maximum Vce saturation (200mV), rise/fall times (4µs, 3µs), operating temperature range (-30°C to 100°C), and package type (16-DIP through-hole).

Q: Are there differences in packaging or handling between these substitute parts?

A: All parts are supplied in tube packaging with identical moisture sensitivity level (MSL 1, unlimited shelf life). Handling and storage requirements are equivalent across all variants.

Q: What is the significance of the suffix variations (BSM, XB, XBG, XBSM)?

A: Suffix variations indicate different manufacturing batches or packaging configurations within the ISP847 series. These designations do not affect electrical performance or functional compatibility. All variants maintain identical parametric specifications for circuit application purposes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ISP847BSM, ISP847XB, ISP847XBG, and ISP847XBSM are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for use in restricted substance-controlled applications.
