ISP847GR Equivalent & Substitute Parts

Part Overview

The ISP847GR is a quad-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin DIP component provides 5300Vrms isolation voltage and is designed for DC input applications requiring galvanic isolation with transistor-based switching outputs. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified within the ISP847 series where electrical and mechanical parameters remain identical across packaging and suffix variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP847GR are identified based on strict parametric equivalence within the ISP847 series. All substitute parts maintain identical electrical specifications across the following critical parameters: 4-channel configuration, 5300Vrms isolation voltage, 50% to 600% current transfer ratio at 5mA, 4µs and 3µs rise/fall times, 35V maximum output voltage, 50mA per-channel output current, 200mV maximum Vce saturation, and -30°C to 100°C operating temperature range. All substitute parts use the same 16-DIP through-hole package with 0.300" (7.62mm) pitch. Substitution differences are limited to suffix designations (X, XG, XGR, XGRG, XGRSM) which indicate packaging variants or manufacturing date codes but do not alter functional or electrical performance. All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts within the ISP847 series are functionally equivalent to the ISP847GR and are suitable for direct replacement in applications requiring quad-channel optoisolation with 5300Vrms isolation voltage and transistor output switching. Selection among available substitutes should be based on inventory availability and delivery requirements, as all parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The ISP847X variant offers the highest current inventory at 5680 pieces. The ISP847XGR, ISP847XGRG, and ISP847XGRSM variants provide alternative sourcing options with comparable stock levels ranging from 747 to 1149 pieces. All parts are active products with confirmed ROHS3 compliance and REACH unaffected status, suitable for applications requiring regulatory compliance in industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Can ISP847X be used as a direct replacement for ISP847GR? A: Yes. The ISP847X is a parametric equivalent with identical electrical specifications, isolation voltage, channel count, output current rating, and operating temperature range. The difference in part number suffix does not affect functional performance or pin compatibility.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All substitute parts use the 16-DIP through-hole package with 0.300" (7.62mm) pitch. PCB layouts designed for ISP847GR are directly compatible with ISP847X, ISP847XG, ISP847XGR, ISP847XGRG, and ISP847XGRSM without modification.

Q: What is the difference between ISP847GR and ISP847XGRSM? A: The electrical and mechanical specifications are identical. Suffix variations (GR versus XGRSM) indicate packaging designations or manufacturing date codes but do not alter isolation voltage, current transfer ratio, output current capability, or operating temperature range.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). Regulatory compliance is consistent across the entire ISP847 series.

Q: Which substitute part should be selected for new designs? A: Selection should be based on availability and lead time. From an engineering perspective, all parts are equivalent. ISP847X offers the highest inventory availability at 5680 pieces, while ISP847XGR, ISP847XGRG, and ISP847XGRSM provide alternative sourcing with comparable specifications.

Q: Is the 5300Vrms isolation voltage maintained across all substitute parts? A: Yes. All substitute parts maintain 5300Vrms isolation voltage. This specification is consistent across ISP847GR, ISP847X, ISP847XG, ISP847XGR, ISP847XGRG, and ISP847XGRSM.
