ISP847B Equivalent & Substitute Parts

Part Overview

The ISP847B 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, with each channel capable of delivering 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 and switching performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP847B are identified within the ISP847 series based on parametric equivalence. All substitute candidates maintain identical specifications across the following critical parameters: 4-channel configuration, 5300Vrms isolation voltage, 130%-260% current transfer ratio at 5mA, 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, ROHS3 compliance, and MSL Level 1 rating. Substitution is valid when all electrical characteristics and physical packaging remain unchanged. The identified substitute part numbers are ISP847XB, ISP847XBG, and ISP847XBSM, each representing variant designations within the same parametric family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts ISP847XB, ISP847XBG, and ISP847XBSM maintain Active product status with full ROHS3 compliance and REACH unaffected designation, matching the ISP847B baseline. Selection among these equivalents may be based on inventory availability: ISP847XBSM (1098 pcs), ISP847XB (956 pcs), and ISP847XBG (707 pcs) are all available in stock. Since all parts share identical electrical specifications, mechanical packaging, and regulatory compliance, any of these substitute part numbers can be selected for direct replacement in existing ISP847B applications without circuit modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ISP847XB, ISP847XBG, and ISP847XBSM be used interchangeably with ISP847B?

A: Yes. All three substitute parts maintain identical electrical parameters including 5300Vrms isolation, 130%-260% current transfer ratio, 50mA output current per channel, and 35V maximum output voltage. Physical packaging is identical 16-DIP through-hole configuration. Direct substitution is valid.

Q: What determines if a part is a valid substitute for ISP847B?

A: Substitution validity is determined by matching all critical parameters: channel count (4), isolation voltage (5300Vrms), current transfer ratio range (130%-260% @ 5mA), output type (transistor), maximum output voltage (35V), per-channel current (50mA), saturation voltage (200mV), switching times (4µs/3µs), operating temperature range (-30°C to 100°C), package type (16-DIP), and compliance certifications (ROHS3, MSL Level 1).

Q: Are there any differences in the suffix designations (B, XB, XBG, XBSM)?

A: The provided data indicates all parts belong to the ISP847 series with identical parametric specifications. Suffix variations represent internal manufacturer designations but do not reflect differences in electrical performance or physical characteristics relevant to circuit design.

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

A: The operating temperature range is -30°C to 100°C for ISP847B and all substitute parts.

Q: Are these parts RoHS compliant?

A: Yes. ISP847B and all substitute parts (ISP847XB, ISP847XBG, ISP847XBSM) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
