Key Parameters

Substitute Part Grouping Explanation

The Coto Technology 2333-05-000 serves as a functionally compatible substitute for the 3660-05-82 based on the following critical electrical parameters:

Equivalent Parameters:

• Identical coil voltage (5VDC)
• Identical contact form (3PST-NO with 3 Form A configuration)
• Identical mounting type (Through Hole)
• Identical termination style (PC Pin)
• Identical operating temperature range (-20°C ~ 85°C)
• Compatible control voltage thresholds (Must Operate: 3.8 VDC; Must Release: 0.4 VDC)

Enhanced Capabilities: The 2333-05-000 offers increased contact current rating (500 mA vs. 250 mA) and elevated maximum switching voltage (200VAC/200VDC vs. 150VAC/150VDC), enabling substitution in applications where the original part is no longer available. The substitute part remains from the same manufacturer, ensuring design consistency and reliability.

Parameter Comparison

Engineering Selection Recommendations

The 2333-05-000 is the designated active substitute for the obsolete 3660-05-82. Both parts are manufactured by Coto Technology and maintain RoHS and REACH compliance. The substitute part carries active product status with improved availability (2181 pcs in stock vs. 683 pcs for the obsolete part).

The 2333-05-000 includes hermetic sealing, providing enhanced environmental protection. This substitution is suitable for new designs and production continuity where the original part is unavailable. The increased contact current rating and switching voltage rating of the substitute provide additional safety margin in switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 2333-05-000 replace the 3660-05-82 in existing designs? A: Yes. Both parts share identical coil voltage, contact configuration, operating temperature range, and control voltage thresholds. The substitute part is electrically compatible for applications within the original part's current and voltage specifications.

Q: What are the main differences between these parts? A: The 2333-05-000 offers doubled contact current capacity (500 mA vs. 250 mA), higher maximum switching voltage (200VAC/200VDC vs. 150VAC/150VDC), hermetic sealing, and faster operation time (0.5 ms vs. 0.75 ms). The substitute requires doubled coil current (28.6 mA vs. 14.3 mA).

Q: Are there packaging differences? A: The 3660-05-82 uses standard packaging, while the 2333-05-000 is supplied in Tray packaging. Both share identical Through Hole mounting and PC Pin termination styles.

Q: What is the impact of the lower coil resistance on circuit design? A: The 2333-05-000 has half the coil resistance (175 Ohms vs. 350 Ohms) at the same 5VDC voltage, resulting in doubled coil current draw (28.6 mA vs. 14.3 mA). Circuit power supply and control circuitry must accommodate this increased current requirement.

Q: Does the hermetic sealing affect electrical performance? A: Hermetic sealing on the 2333-05-000 enhances environmental protection and contact reliability in humid or corrosive atmospheres. This does not degrade electrical performance compared to the unsealed original part.
