Key Parameters

Substitute Part Grouping Explanation

The PS2501-1LG qualifies for substitution with parts that maintain identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Current Transfer Ratio: 200% (Min) to 400% (Max) @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 300mV
• Operating Temperature Range: -30°C ~ 100°C
• Package / Case: 4-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both PS2501-1LG and PS2501-1XLG are active production components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and are suitable for applications requiring 5300Vrms isolation with single-channel transistor output in 4-DIP through-hole packages. The PS2501-1XLG offers higher inventory availability at 1016 units compared to 624 units for the PS2501-1LG.

Frequently Asked Questions (FAQ)

Q: Can PS2501-1XLG be used as a direct replacement for PS2501-1LG?

A: Yes. Both parts are parametric equivalents with identical isolation voltage, current transfer ratio, output characteristics, temperature range, and 4-DIP package specifications. They are interchangeable in circuit design and PCB layout.

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

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications.

Q: What determines substitution eligibility for PS2501-1LG?

A: Substitution eligibility is determined by matching all critical parameters: 5300Vrms isolation voltage, single channel configuration, 200-400% current transfer ratio at 5mA, 80V maximum output voltage, 50mA output current, 300mV maximum Vce saturation, -30°C to 100°C operating temperature, and 4-DIP through-hole package format.

Q: Can parts from different manufacturers substitute for PS2501-1LG?

A: Substitution with parts from other manufacturers is not addressed in this reference. Only Isocom Components 2004 LTD parts meeting the specified parameters are documented as equivalents.

Q: Are there packaging or lead-form variations between PS2501-1LG and PS2501-1XLG?

A: No. Both parts use identical 4-DIP (0.400", 10.16mm) through-hole packaging with the same physical and electrical interface specifications.
