Parameter Comparison

Engineering Selection Recommendations

The PS2502-4-A serves as the direct electrical and mechanical equivalent to the obsolete PS2502-4. Both parts share identical electrical performance characteristics and physical packaging specifications. The primary distinction is product lifecycle status and RoHS compliance:

The PS2502-4 carries Obsolete status with RoHS non-compliance. The PS2502-4-A carries Not For New Designs status with ROHS3 compliance. For new design implementations or inventory replenishment, the PS2502-4-A is the appropriate selection when 4-channel, 5000Vrms isolated Darlington output functionality is required in a 16-DIP package configuration.

Both parts remain subject to REACH compliance requirements. Component selection should account for product lifecycle strategy and manufacturing compliance mandates specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can PS2502-4-A be used as a direct replacement for PS2502-4? A: Yes. The PS2502-4-A provides identical electrical and mechanical specifications. Direct substitution requires no circuit modification, trace routing adjustment, or firmware changes. The 16-DIP package pinout and all electrical operating parameters are equivalent.

Q: What is the difference between Obsolete and Not For New Designs status? A: Obsolete status indicates the part is no longer manufactured and existing inventory is limited. Not For New Designs status indicates the manufacturer will fulfill existing orders but discourages incorporation into new product designs. Both statuses reflect product lifecycle discontinuation.

Q: Are there differences in RoHS compliance between the parts? A: The PS2502-4 is RoHS non-compliant. The PS2502-4-A is ROHS3 compliant. If RoHS compliance is required for your application or market region, the PS2502-4-A must be selected. Both parts remain REACH Affected.

Q: Will the PS2502-4-A work in existing circuit boards designed for PS2502-4? A: Yes. Identical package configuration (16-DIP), pinout, and electrical parameters permit drop-in replacement without PCB redesign, component repositioning, or electrical circuit modification.

Q: What isolation voltage is provided by these parts? A: Both parts provide 5000Vrms isolation voltage, suitable for applications requiring galvanic isolation across high-potential boundaries.

Q: What is the maximum output current per channel? A: The maximum output current per channel is 160mA for both the PS2502-4 and PS2502-4-A, with a maximum output voltage rating of 40V.
