8002-12-01 Equivalent & Substitute Parts

Part Overview

The Coto Technology 8002-12-01 is a reed relay with DPST-NO (2 Form A) contact configuration, rated for 500 mA at 12VDC coil voltage. This part is classified as Obsolete, making it necessary to identify active alternative models that maintain electrical and mechanical compatibility for seamless integration into existing designs or new applications requiring equivalent performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 8002-12-01 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: Must be 12VDC
• Contact Form: Must maintain DPST-NO (2 Form A) configuration
• Contact Rating (Current): Must be 500 mA minimum
• Switching Voltage: Must support 200VAC, 200VDC maximum
• Mounting Type: Must be Through Hole with PC Pin termination
• Coil Current and Resistance: Must remain 24 mA and 500 Ohms respectively
• Operating Temperature Range: Must cover -20°C ~ 85°C

The 8L02-12-01 meets all these critical parameters and is classified as Active with current inventory availability. The 8L01-12-011, while manufactured by Coto Technology with matching electrical characteristics, features a SPST-NO (1 Form A) contact form, reducing its contact channels from two to one and limiting its functional equivalence for applications requiring dual independent switching paths.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 8L02-12-01

The 8L02-12-01 is the direct functional equivalent for the obsolete 8002-12-01. Both parts maintain identical DPST-NO contact configuration, electrical ratings, and operational parameters. The 8L02-12-01 carries Active product status with superior inventory availability (3801 units in stock), ROHS3 compliance, and belongs to the 8L series representing the current manufacturing generation.

Secondary Option: 8L01-12-011

The 8L01-12-011 is a single-pole variant (SPST-NO) suitable only for applications requiring single independent switching path. This part is not a direct substitute for dual-channel applications but maintains all other electrical and thermal characteristics, including coil voltage, contact rating, switching voltage, and operating temperature range. The choice of this part requires circuit redesign to accommodate reduced contact channels.

Both substitute parts satisfy regulatory requirements (RoHS, REACH, EAR99 classification) and share the same termination methodology (PC Pin through-hole mounting), enabling mechanical compatibility with printed circuit board layouts designed for the 8002-12-01.

Frequently Asked Questions (FAQ)

Q: Can the 8L02-12-01 directly replace the 8002-12-01 in existing designs?

A: Yes. The 8L02-12-01 is a direct electrical and mechanical substitute. Both parts feature identical 12VDC coil voltage, 500 mA contact rating, DPST-NO contact form, 200VAC/200VDC switching voltage, PC Pin through-hole mounting, and identical operating temperature range. No circuit modifications are required.

Q: What is the primary difference between the 8L01-12-011 and the 8L02-12-01?

A: The 8L01-12-011 is a single-pole relay (SPST-NO) with one independent contact pair, while the 8L02-12-01 is a double-pole relay (DPST-NO) with two independent contact pairs. Both operate at identical coil voltage and current ratings. Selection depends on whether the application requires one or two independent switching paths.

Q: Are there packaging differences between substitute parts?

A: The 8002-12-01 uses dash packaging, while both 8L01-12-011 and 8L02-12-01 are supplied in Tube packaging. The functional and electrical characteristics remain unchanged; packaging differences affect only supply chain and handling procedures.

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

A: Yes. Both substitute parts (8L01-12-011 and 8L02-12-01) are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99. Compliance standards are equivalent or enhanced compared to the RoHS Compliant classification of the main part.

Q: What is the inventory status of these parts?

A: The 8002-12-01 (Obsolete) has 751 units in stock. The 8L01-12-011 (Active) has 1041 units available. The 8L02-12-01 (Active) has 3801 units available, providing the most secure long-term supply for new designs.

Q: Are there timing differences between the substitute parts?

A: The 8002-12-01 has a 1 ms release time, while both substitute parts (8L01-12-011 and 8L02-12-01) have 0.5 ms release time, representing faster contact recovery. Operate time remains constant at 0.5 ms across all three parts.
