ISP847CSM Equivalent & Substitute Parts

Part Overview

The ISP847CSM 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 part is classified as Active status and is ROHS3 compliant. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the ISP847 series variants, ensuring direct functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP847CSM are identified within the ISP847 series based on parametric equivalence. The substitution criteria are strictly defined by the following parameters that must remain identical:

• Number of Channels: 4
• Voltage - Isolation: 5300Vrms
• Current Transfer Ratio: 200% (Min) @ 5mA, 400% (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
• RoHS Status: ROHS3 Compliant

All substitute parts maintain these exact specifications, differing only in packaging designation (tube) and inventory levels. The ISP847 series variants (ISP847XC, ISP847XCG, ISP847XCSM) are direct parametric equivalents suitable for one-to-one replacement.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed (ISP847XC, ISP847XCG, ISP847XCSM) are parametrically equivalent to the ISP847CSM and maintain Active product status. Each variant is ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements. Selection among these equivalents may be based on inventory availability: ISP847CSM (1113 pcs), ISP847XCG (958 pcs), ISP847XCSM (738 pcs), and ISP847XC (917 pcs). All parts are supplied in tube packaging and are suitable for direct substitution in applications requiring quad-channel optoisolation with 5300Vrms isolation voltage and transistor output configuration.

Frequently Asked Questions (FAQ)

Q: Can ISP847XC, ISP847XCG, and ISP847XCSM be used interchangeably with ISP847CSM?

A: Yes. All parts maintain identical electrical specifications including isolation voltage (5300Vrms), channel count (4), current transfer ratio (200-400% @ 5mA), output current (50mA per channel), and package configuration (16-DIP through-hole). They are direct parametric equivalents.

Q: What determines substitution eligibility for ISP847 series optoisolators?

A: Substitution is determined by matching the following critical parameters: number of channels, isolation voltage rating, current transfer ratio range, maximum output voltage, output current per channel, saturation voltage, switching times, operating temperature range, and physical package dimensions. All listed substitutes maintain these specifications identically.

Q: Are there any differences in compliance or certifications between these parts?

A: No. All parts carry identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (unlimited moisture sensitivity), and Active product status. Regulatory and environmental certifications are equivalent across all variants.

Q: Does packaging designation affect functional compatibility?

A: No. All parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging. The packaging designation (tube) is a supply format only and does not affect electrical performance or circuit compatibility.

Q: What is the significance of the part number suffix variations (CSM, XC, XCG, XCSM)?

A: The suffixes indicate internal manufacturing or distribution variants within the ISP847 series. These designations do not reflect electrical or mechanical differences; all variants maintain identical specifications for isolation voltage, channel configuration, output characteristics, and package format.
