Key Parameters

Substitute Part Grouping Explanation

The 2333-05-000 qualifies as a substitute for the 3660-05-72 based on the following matched parameters:

• Coil Voltage: Both operate at 5VDC
• Contact Form: Both are 3PST-NO (3 Form A) configuration
• Mounting Type: Both are through-hole mounted
• Termination Style: Both use PC pin termination
• Must Operate Voltage: Both require 3.8 VDC minimum
• Operating Temperature Range: Both rated -20°C ~ 85°C
• Compliance: Both are RoHS Compliant and REACH Unaffected

The 2333-05-000 provides enhanced specifications with higher current rating (500 mA vs. 250 mA) and increased switching voltage capability (200VAC/200VDC vs. 150VAC/150VDC), making it functionally compatible for equivalent or less demanding circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 2333-05-000 is the recommended substitute for the obsolete 3660-05-72. The substitute maintains identical coil voltage, contact configuration, mounting type, and temperature operating range. Both parts are RoHS and REACH compliant, with the 2333-05-000 meeting ROHS3 standards and offering active product status ensuring long-term availability.

The 2333-05-000 provides enhanced performance specifications: doubled contact current rating (500 mA vs. 250 mA), increased switching voltage (200VAC/200VDC vs. 150VAC/150VDC), and improved operate time (0.5 ms vs. 0.75 ms). These enhancements make the 2333-05-000 suitable for direct substitution in legacy applications designed for the 3660-05-72.

Frequently Asked Questions (FAQ)

Q: Can the 2333-05-000 replace the 3660-05-72 in existing designs? A: Yes. The 2333-05-000 maintains identical coil voltage (5VDC), contact form (3PST-NO), mounting type (through-hole), and termination style (PC pin). Enhanced specifications provide additional performance margin.

Q: What are the main differences between these parts? A: The 2333-05-000 offers higher current capacity (500 mA vs. 250 mA), increased switching voltage (200VAC/200VDC vs. 150VAC/150VDC), faster operate time (0.5 ms vs. 0.75 ms), and active product status versus obsolete status.

Q: Are there packaging differences? A: The 3660-05-72 specifies standard packaging, while the 2333-05-000 is available in Tray packaging. Both use identical PC pin termination.

Q: Why is the coil resistance different between the two parts? A: The 2333-05-000 operates at 28.6 mA coil current (versus 14.3 mA for the 3660-05-72), requiring proportionally lower coil resistance (175 Ohms vs. 350 Ohms) to achieve the same 5VDC activation voltage.

Q: Are both parts RoHS compliant? A: Yes. The 3660-05-72 is RoHS Compliant. The 2333-05-000 is ROHS3 Compliant, representing updated compliance standards.
