Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 8002-05-00 are identified based on strict electrical and mechanical parameter matching. The following parameters establish substitution eligibility:

Core Electrical Requirements:

• Coil Voltage: 5VDC
• Contact Form: DPST-NO (2 Form A)
• Contact Rating: 500 mA minimum
• Switching Voltage: 200VAC, 200VDC maximum or greater
• Coil Current: 25 mA
• Coil Type: Non Latching

Core Mechanical Requirements:

• Mounting Type: Through Hole
• Termination Style: PC Pin

Operational Requirements:

• Must Operate Voltage: 3.8 VDC or lower
• Must Release Voltage: 0.5 VDC or higher
• Operate and Release Times: Compatible with 0.5 ms or faster response requirements

Two active substitute parts meet these criteria with documented parameter compatibility.

Parameter Comparison

Engineering Selection Recommendations

Coto Technology 8L02-05-00 is the preferred direct substitute for the obsolete 8002-05-00. This part maintains identical electrical characteristics and coil parameters, with the same operating and release time specifications. The 8L02-05-00 is currently in active production status with ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and production continuity.

TE Connectivity V23100V4305B000 serves as a cross-manufacturer alternative with equivalent functional capacity. This part meets all core electrical and mechanical requirements with extended temperature operating range (-40°C to 85°C versus -20°C to 85°C). Minor timing variations exist: the V23100V4305B000 exhibits 0.75 ms operate time and 0.15 ms release time compared to the 0.5 ms specifications of the original design. The V23100V4305B000 carries RoHS Compliant status and represents an active product line option for applications tolerant of these timing characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 8L02-05-00 be used as a direct replacement for the 8002-05-00? A: Yes. The 8L02-05-00 shares identical coil voltage, contact rating, contact form, coil current, and operating/release timing specifications. The primary difference is product status (active versus obsolete) and RoHS certification revision level.

Q: What are the key differences between the Coto 8L02-05-00 and the TE Connectivity V23100V4305B000? A: Both parts satisfy the core electrical requirements of 5VDC coil voltage, 500 mA contact rating, and DPST switching form. The V23100V4305B000 operates at a lower must-operate voltage (3.5 VDC versus 3.8 VDC), exhibits slower operate time (0.75 ms versus 0.5 ms), but provides faster release time (0.15 ms versus 0.5 ms) and extended low-temperature operation (-40°C versus -20°C minimum).

Q: Are packaging differences relevant for PCB assembly compatibility? A: Both substitute parts utilize through-hole PC pin termination compatible with the original design. The 8L02-05-00 is packaged in tube form, matching standard Coto relay distribution. The V23100V4305B000 is packaged in tube form consistent with TE Connectivity standards. Mechanical footprint and lead spacing remain compatible with the original design.

Q: What compliance certifications apply to the substitute parts? A: The 8L02-05-00 carries ROHS3 Compliant designation. The V23100V4305B000 carries RoHS Compliant designation. Both parts are REACH Unaffected and carry EAR99 export classification, maintaining regulatory alignment with the original 8002-05-00.

Q: Which substitute should be selected for a new design? A: The 8L02-05-00 is the recommended choice for designs requiring timing specifications identical to the original 8002-05-00. The V23100V4305B000 is suitable for applications where the slightly slower operate time and faster release time can be accommodated, particularly when extended low-temperature operation is beneficial.
