ISP847BLSM Equivalent & Substitute Parts

Part Overview

The ISP847BLSM is a quad-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin DIP component provides galvanic isolation up to 5300Vrms across four independent channels, each capable of delivering 50mA output current. The device is classified as Active status and is suitable for applications requiring high-voltage isolation with DC input control and transistor switching output. Substitute parts are identified based on identical electrical specifications and mechanical compatibility within the ISP847 series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP847BLSM are identified within the ISP847 series based on identical electrical and mechanical parameters. The substitution criteria are strictly defined by the following parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 4
• Current Transfer Ratio: 200% (Min) @ 5mA, 600% (Max) @ 5mA
• Rise / Fall Time: 4µs, 3µs
• Output Type: Transistor
• Voltage - Output (Max): 35V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Operating Temperature: -30°C ~ 100°C
• Package / Case: 16-DIP (0.300", 7.62mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts maintain identical specifications across these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—ISP847XBL, ISP847XBLG, and ISP847XBLSM—are parametrically equivalent to the ISP847BLSM and maintain Active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use. Selection among these equivalents may be based on inventory availability and lead time considerations, as all parts are functionally and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ISP847XBL, ISP847XBLG, and ISP847XBLSM be used as direct replacements for ISP847BLSM?

A: Yes. All three substitute parts are parametrically equivalent to the ISP847BLSM across all electrical and mechanical specifications, including isolation voltage, channel count, current transfer ratio, output characteristics, and package dimensions. Direct substitution is supported without circuit modification.

Q: Are there differences in isolation voltage or output current between the main part and substitutes?

A: No. All parts maintain identical isolation voltage (5300Vrms), output current per channel (50mA), and maximum output voltage (35V). Substitution does not affect circuit performance in these critical parameters.

Q: Do all parts use the same 16-DIP package?

A: Yes. The ISP847BLSM and all substitute parts use the 16-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical compatibility on PCBs designed for any of these part numbers.

Q: Are there compliance or regulatory differences between these parts?

A: No. All parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. Regulatory status is uniform across the group.

Q: What is the operating temperature range for these optoisolators?

A: All parts operate across the temperature range of -30°C to 100°C, providing consistent thermal performance across the substitute group.
