ISP814G Equivalent & Substitute Parts

Part Overview

The ISP814G is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This single-channel device provides galvanic isolation with AC/DC input capability and is housed in a 4-DIP package. The part is currently active in production with 1,075 units in stock. Alternative models may be required due to inventory constraints, supply chain considerations, or specific application requirements within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISP814G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

• Single-channel optoisolator configuration
• 7.5Vpk isolation voltage
• Current transfer ratio range: 20% to 300% @ 1mA
• Transistor output type with 35V maximum output voltage and 50mA per-channel current rating
• 4µs rise time and 3µs fall time characteristics
• AC/DC input capability
• 4-DIP through-hole package (0.400", 10.16mm)
• Operating temperature range: -30°C to 100°C
• ROHS3 compliance and REACH unaffected status

The ISP814XG meets all these criteria and is classified as a parametric equivalent within the ISP814 series.

Parameter Comparison

Engineering Selection Recommendations

Both the ISP814G and ISP814XG are active products manufactured by Isocom Components 2004 LTD with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The ISP814G currently maintains higher inventory (1,075 units) compared to the ISP814XG (981 units). Both parts are suitable for direct substitution in applications requiring single-channel optoisolation with the specified electrical characteristics and 4-DIP through-hole package configuration.

Frequently Asked Questions (FAQ)

Q: Can ISP814XG replace ISP814G in existing designs? A: Yes. The ISP814XG is a parametric equivalent with identical electrical specifications, isolation voltage, current transfer ratio, output characteristics, and package configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certifications? A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status, with matching moisture sensitivity levels (MSL 1 - Unlimited).

Q: What determines substitution eligibility for ISP814 series optoisolators? A: Substitution is determined by matching all critical parameters: single-channel configuration, 7.5Vpk isolation voltage, 20-300% current transfer ratio range, transistor output type, 35V maximum output voltage, 50mA per-channel current, 4-DIP through-hole package, and -30°C to 100°C operating temperature range.

Q: Are both parts suitable for AC and DC input applications? A: Yes. Both ISP814G and ISP814XG support AC and DC input types with identical rise and fall time characteristics (4µs and 3µs respectively).

Q: What is the package compatibility between these parts? A: Both parts use identical 4-DIP through-hole packages with 0.400" (10.16mm) spacing, ensuring mechanical and electrical compatibility on PCBs designed for either part number.
