Engineering Selection Recommendations

Coto Technology 8L02-12-00 (Direct Equivalent)

The 8L02-12-00 is the primary substitute for the obsolete 8002-12-00. Both components are manufactured by Coto Technology and share identical electrical specifications across all critical parameters: coil voltage, contact form, current rating, switching voltage, coil current, coil resistance, and timing characteristics. The 8L02-12-00 maintains the same operating temperature range and possesses active product status with ROHS3 compliance, providing long-term availability. This part is available in tube packaging with 1806 units in stock.

TE Connectivity V23100V4312B000 (Similar Alternative)

The V23100V4312B000 from TE Connectivity Potter & Brumfield Relays serves as a secondary substitute option. This component matches all mandatory electrical criteria and provides superior performance characteristics in several areas: lower must-operate voltage (8.4 VDC versus 9.6 VDC), faster release time (0.15 ms versus 0.5 ms), and extended operating temperature range (-40°C to 85°C versus -20°C to 85°C). The operate time is marginally longer at 0.75 ms, and the must-release voltage is higher at 1.8 VDC. Contact material is specified as Ruthenium, providing enhanced contact durability. This part is available in tube packaging with 864 units in stock and maintains active product status with RoHS compliance.

Both substitutes satisfy regulatory requirements (RoHS, REACH, EAR99 classification) and moisture sensitivity specifications identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can the 8L02-12-00 be used as a direct replacement for the 8002-12-00?

A: Yes. The 8L02-12-00 is a direct equivalent substitute. Both parts share identical coil voltage (12VDC), contact form (DPST-NO), current rating (500 mA), switching voltage (200VAC/200VDC), coil current (24 mA), coil resistance (500 Ohms), and timing specifications (0.5 ms operate and release times). The 8L02-12-00 is manufactured by the same supplier (Coto Technology) and maintains active product status.

Q: What are the differences between the 8L02-12-00 and V23100V4312B000?

A: Both parts satisfy the mandatory electrical requirements of the 8002-12-00. The V23100V4312B000 offers lower must-operate voltage (8.4 VDC versus 9.6 VDC), faster release time (0.15 ms versus 0.5 ms), and wider operating temperature range (-40°C to 85°C). The operate time is 0.75 ms (versus 0.5 ms), and must-release voltage is 1.8 VDC (versus 1 VDC). The V23100V4312B000 uses Ruthenium contact material and is manufactured by TE Connectivity.

Q: Are there packaging differences between these substitutes?

A: The 8002-12-00 original specification does not define packaging. Both substitute parts are supplied in tube packaging: the 8L02-12-00 with 1806 units in stock and the V23100V4312B000 with 864 units in stock.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. The 8002-12-00 is RoHS Compliant, the 8L02-12-00 is ROHS3 Compliant, and the V23100V4312B000 is RoHS Compliant. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Which substitute should be selected for new designs?

A: The 8L02-12-00 is recommended for direct replacement applications requiring identical performance characteristics and same-manufacturer sourcing. The V23100V4312B000 is suitable for applications that benefit from lower operating voltage threshold, faster release response, or extended temperature range operation.

Q: Are the coil resistance values identical across all three parts?

A: Yes. All three parts specify 500 Ohms coil resistance, ensuring equivalent drive circuit requirements and power consumption characteristics.

Q: What is the moisture sensitivity level for these relays?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
