Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3650-12-82 is based on the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

• Coil voltage: 12VDC
• Contact form: 3PST-NO (3 Form A)
• Mounting type: Through Hole
• Termination style: PC Pin
• Coil type: Non Latching
• Operating temperature range: -20°C ~ 85°C
• Must operate voltage: 9 VDC minimum
• Must release voltage: 1 VDC maximum

Allowable Variation Parameters:

• Contact rating current: May increase from 250 mA to higher ratings
• Switching voltage: May increase from 150VAC/150VDC to higher ratings
• Coil current: May vary based on coil resistance changes
• Coil resistance: May vary inversely with coil current
• Operate and release times: May vary within acceptable switching performance windows
• Packaging format: May differ (tray versus other formats)
• Product status: Active substitutes preferred over obsolete

The Coto Technology 2333-12-000 meets all mandatory matching parameters while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Coto Technology 2333-12-000 serves as a direct functional substitute for the obsolete 3650-12-82 reed relay. Both components share identical coil voltage, contact form, mounting configuration, and operating voltage thresholds. The 2333-12-000 is currently in active production status with enhanced electrical performance specifications.

The substitute part provides increased contact current rating (500 mA versus 250 mA) and higher switching voltage capability (200VAC/200VDC versus 150VAC/150VDC), making it suitable for applications requiring the original 3650-12-82 specifications while offering additional performance margin. The 2333-12-000 incorporates hermetic sealing, providing enhanced environmental protection compared to the original part.

Both components maintain identical regulatory compliance status under RoHS and REACH requirements, with matching ECCN and HTSUS classifications. The substitute part operates within the same temperature range and maintains equivalent voltage threshold characteristics for reliable switching performance.

Frequently Asked Questions (FAQ)

Q: Can the 2333-12-000 directly replace the 3650-12-82 in existing circuit designs?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (3PST-NO), mounting type (through-hole), and termination style (PC pin). The substitute part maintains the same must-operate and must-release voltage thresholds, ensuring compatible switching behavior in existing applications.

Q: What are the differences in electrical performance between these two relays?

A: The 2333-12-000 provides higher contact current rating (500 mA versus 250 mA) and increased switching voltage capability (200VAC/200VDC versus 150VAC/150VDC). The substitute part operates with faster switching time (0.5 ms operate time versus 0.75 ms) and includes hermetic sealing for enhanced environmental protection.

Q: Are there packaging differences between the 3650-12-82 and 2333-12-000?

A: The 3650-12-82 packaging format is not specified in available documentation. The 2333-12-000 is supplied in tray packaging. Both components use identical through-hole PC pin termination suitable for standard PCB assembly processes.

Q: Do both relays meet current regulatory requirements?

A: Yes. The 3650-12-82 is RoHS Compliant and REACH Unaffected. The 2333-12-000 is ROHS3 Compliant and REACH Unaffected. Both components carry identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications.

Q: What is the coil current difference, and does it affect circuit design?

A: The 3650-12-82 requires 6 mA coil current with 2 kOhms coil resistance. The 2333-12-000 requires 12 mA coil current with 1 kOhms coil resistance. Circuit designs must accommodate the increased coil current draw of the substitute part through appropriate driver circuit sizing.

Q: Is the 2333-12-000 available in higher quantities than the 3650-12-82?

A: The 2333-12-000 is in active production status with 1488 pieces in current inventory. The 3650-12-82 is obsolete with limited remaining stock of 901 pieces.
