ISP814ASM Equivalent & Substitute Parts

Part Overview

The ISP814ASM is a single-channel optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation for AC and DC input signals with a maximum isolation voltage of 7.5Vpk and is designed for surface mount applications in 4-SMD gull wing packaging. The part is currently active in production with 753 units in stock. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The ISP814ASM has one parametric equivalent substitute: ISP814AXSM. This substitute relationship is established based on strict electrical and mechanical parameter matching across all critical specifications:

Key Parameters for Substitution Equivalence:

• Single channel optoisolator configuration
• Identical isolation voltage rating of 7.5Vpk
• Matching current transfer ratio range (50% to 150% @ 1mA)
• Identical rise and fall time characteristics (4µs, 3µs)
• Dual input type capability (AC, DC)
• Transistor output topology with 35V maximum output voltage
• 50mA per-channel output current rating
• Identical Vce saturation specification (200mV maximum)
• Matching operating temperature range (-30°C ~ 100°C)
• Identical surface mount 4-SMD gull wing package
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

Both parts belong to the ISP814 series and share identical functional and physical characteristics, making them direct parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both ISP814ASM and ISP814AXSM are active production parts from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts should be based on availability and procurement requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards. The ISP814AXSM currently has higher inventory availability (1132 units versus 753 units), which may influence procurement decisions for high-volume applications. Both parts are suitable for direct substitution in any application designed for the ISP814 series single-channel optoisolator.

Frequently Asked Questions (FAQ)

Q: Can ISP814AXSM be used as a direct replacement for ISP814ASM? A: Yes. Both parts are parametric equivalents with identical electrical specifications, isolation voltage, current transfer ratios, timing characteristics, output ratings, and operating temperature range. They share the same 4-SMD gull wing package and are both active production parts with equivalent compliance certifications.

Q: Are there any differences in the 4-SMD gull wing package between these parts? A: No. Both parts use identical 4-SMD gull wing surface mount packaging with the same physical dimensions and pin configuration, allowing direct PCB footprint compatibility.

Q: What determines substitution eligibility for ISP814 series optoisolators? A: Substitution eligibility is determined by matching the following parameters: number of channels (1), isolation voltage (7.5Vpk), current transfer ratio range (50-150% @ 1mA), rise/fall time (4µs, 3µs), input type (AC/DC), output type (transistor), maximum output voltage (35V), output current (50mA), Vce saturation (200mV), operating temperature range (-30°C to 100°C), and package type (4-SMD gull wing).

Q: Do both parts meet the same compliance standards? A: Yes. Both ISP814ASM and ISP814AXSM are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain considerations. The ISP814AXSM has higher current stock levels, which may provide supply chain advantages for production quantities.
