ISP847BLG Equivalent & Substitute Parts

Part Overview

The ISP847BLG 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 50mA output current. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the ISP847 series, enabling direct replacement in applications requiring equivalent isolation performance and switching characteristics.

• Voltage - Isolation: 5300Vrms
• Number of Channels: 4
• Current Transfer Ratio: 200% (Min) to 600% (Max) @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 35V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 200mV
• Rise / Fall Time: 4µs, 3µs
• Operating Temperature: -30°C ~ 100°C
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Product Status: Active
• RoHS Status: RoHS3 Compliant
• REACH Status: REACH Unaffected

All identified substitute parts maintain identical specifications across these parameters, ensuring direct functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts identified—ISP847XBL, ISP847XBLG, and ISP847XBLSM—maintain full parametric equivalence with the ISP847BLG across all electrical and mechanical specifications. Selection among these parts is based on availability and compliance requirements:

• All parts carry Active product status, confirming ongoing manufacturer support and availability.
• All parts maintain RoHS3 compliance and REACH unaffected designation, meeting environmental and regulatory requirements.
• Moisture Sensitivity Level (MSL) is rated 1 (Unlimited) across all variants, indicating no special moisture handling requirements during storage or assembly.
• Through-hole 16-DIP packaging ensures compatibility with standard PCB assembly processes and existing board layouts designed for the ISP847BLG.

Component selection should prioritize inventory availability and lead time requirements, as all parts are functionally interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ISP847XBL, ISP847XBLG, and ISP847XBLSM be used as direct replacements for ISP847BLG?

A: Yes. All three parts are parametric equivalents with identical electrical specifications, isolation voltage, channel configuration, output characteristics, and package dimensions. Direct substitution is supported without circuit modification.

Q: What determines whether a part qualifies as a substitute for ISP847BLG?

A: Substitution is based on matching all critical parameters: 5300Vrms isolation voltage, 4-channel configuration, 200-600% current transfer ratio, 35V maximum output voltage, 50mA per-channel output current, 200mV maximum Vce saturation, 4µs/3µs rise/fall times, -30°C to 100°C operating temperature range, 16-DIP through-hole package, and Active product status with RoHS3 compliance.

Q: Are there any differences in packaging or handling between ISP847BLG and its substitutes?

A: No. All parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging with MSL rating of 1 (Unlimited), requiring no special moisture control measures. PCB footprints and assembly processes remain unchanged.

Q: What is the significance of the part number suffix variations (BLG, XBL, XBLG, XBLSM)?

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 meet identical specifications for isolation, switching speed, output current, and temperature range.

Q: Can these parts be used interchangeably in high-reliability applications?

A: All identified substitutes carry Active product status and full RoHS3 compliance. Selection should be based on specific application requirements, compliance certifications needed, and component availability. No technical limitations prevent interchangeable use within the specified operating parameters.
