Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP620-2 are qualified based on strict parametric equivalence across the following critical criteria:

• Isolation Voltage: 5300Vrms minimum
• Channel Configuration: Dual-channel (2 channels)
• Output Stage: Transistor output topology
• Current Transfer Ratio: 50% minimum and 600% maximum at 5mA
• Rise / Fall Time: 4µs rise, 3µs fall
• Input Capability: AC and DC input support
• Maximum Output Voltage: 55V
• Output Current per Channel: 50mA
• Saturation Voltage: 400mV maximum
• Operating Temperature Range: -30°C to 100°C
• Package: 8-DIP through-hole form factor
• Compliance: ROHS3 compliant, REACH unaffected

All identified substitutes maintain these parameters without deviation, ensuring functional and electrical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TLP620-2, ISP620-2X, and TLP620-2X—are active products from Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on packaging format (tube vs. standard) and current inventory availability. The TLP620-2X variant offers the highest stock level at 2365 units. All parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. Through-hole 8-DIP packaging ensures compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ISP620-2X and TLP620-2X be used interchangeably with TLP620-2?

A: Yes. All three parts maintain identical electrical parameters including isolation voltage, channel configuration, current transfer ratio, output characteristics, and operating temperature range. The 8-DIP through-hole package is identical across all variants, enabling direct pin-for-pin substitution.

Q: What is the difference between TLP620-2 and TLP620-2X?

A: The primary difference is packaging format. TLP620-2 is supplied in standard packaging, while TLP620-2X is supplied in tube packaging. Electrical specifications and performance characteristics are identical.

Q: Are there packaging considerations when substituting these parts?

A: No. All parts use the same 8-DIP (0.300", 7.62mm) through-hole package. PCB footprints and assembly processes remain unchanged regardless of which variant is selected.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. TLP620-2, ISP620-2X, and TLP620-2X are all ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What parameters must remain constant for substitution?

A: Substitution is valid when the following parameters are maintained: 5300Vrms isolation voltage, dual-channel configuration, transistor output, 50-600% current transfer ratio at 5mA, 4µs/3µs rise/fall time, AC/DC input capability, 55V maximum output voltage, 50mA per-channel output current, 400mV maximum saturation voltage, -30°C to 100°C operating range, and 8-DIP through-hole package.
