Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TN2-L-5V are identified based on the following critical parameters that must align for functional compatibility:

• Coil Voltage: 5VDC (exact match required)
• Contact Form: DPDT (2 Form C) (exact match required)
• Coil Current: 20 mA (exact match required)
• Coil Resistance: 250 Ohms (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Style: PC Pin (exact match required)
• Must Operate Voltage: 3.75 VDC (exact match required)

The substitute part 2-1462038-1 meets all critical electrical and mechanical parameters. While the contact rating is higher (2A versus 1A) and the switching voltage specification is elevated, these represent enhanced capabilities that maintain backward compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The 2-1462038-1 substitute part is suitable for applications currently using the TN2-L-5V. The substitute maintains all critical electrical parameters including coil voltage, coil current, coil resistance, and switching timing characteristics. The substitute part carries Active product status, ensuring continued availability and supply chain support.

The substitute part is RoHS3 compliant, providing regulatory advantage over the original obsolete component. Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance consistency.

The enhanced contact rating (2A versus 1A) and higher switching voltage specification of the substitute part provide additional operational margin without introducing incompatibility. The hermetic seal rating of the substitute part exceeds the fully sealed specification of the original component, offering improved environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the 2-1462038-1 directly replace the TN2-L-5V in existing designs?

A: Yes. The substitute part maintains identical coil voltage (5VDC), coil current (20 mA), coil resistance (250 Ohms), contact form (DPDT), mounting type (through hole), and termination style (PC pin). Switching timing (3 ms operate and release) and must-operate voltage (3.75 VDC) are identical.

Q: What are the differences between the two parts?

A: The 2-1462038-1 features a higher contact rating (2A versus 1A), elevated switching voltage specification (250VAC/220VDC versus 125VAC/110VDC), hermetic sealing versus full sealing, and an extended operating temperature range (-40°C to 85°C versus -40°C to 70°C). The substitute part is Active status with RoHS3 compliance.

Q: Are there packaging considerations for substitution?

A: The TN2-L-5V is packaged in standard through-hole format with PC pin termination. The 2-1462038-1 substitute uses identical through-hole mounting and PC pin termination, ensuring mechanical compatibility with existing PCB layouts.

Q: Does the higher contact rating of the substitute part affect circuit design?

A: No. The higher contact rating (2A) of the substitute part represents enhanced capability. Applications designed for 1A operation remain fully compatible, as the substitute part operates within the original design parameters.

Q: What compliance advantages does the substitute part offer?

A: The 2-1462038-1 is RoHS3 compliant, providing regulatory advantage for new designs and ongoing system support. Both parts maintain identical REACH and ECCN classifications.
