Key Parameters

Substitute Part Grouping Explanation

Substitution of the TN2-L2-9V is determined by the following critical parameters:

• Coil Voltage: Must be 9VDC to maintain circuit compatibility
• Contact Form: Must be DPDT (2 Form C) for equivalent switching functionality
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct board connection
• Coil Type: Must be Latching, Dual Coil to preserve control logic
• Must Operate Voltage: Must be 6.75 VDC or lower to ensure reliable operation across the specified voltage range

The V23079B1206B301 meets all these critical substitution criteria. While the substitute part offers enhanced specifications in contact rating (2A vs 1A), switching voltage (250VAC/220VDC vs 125VAC/110VDC), and operating temperature range (-40°C ~ 85°C vs -40°C ~ 70°C), these represent improvements that maintain backward compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The V23079B1206B301 is the qualified substitute for the obsolete TN2-L2-9V. Selection is based on the following factors:

Product Status: The TN2-L2-9V is obsolete, while the V23079B1206B301 is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Compliance: Both parts carry identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency. The V23079B1206B301 is RoHS Compliant, providing additional environmental compliance assurance.

Functional Equivalence: Both relays share identical coil voltage (9VDC), contact form (DPDT), coil type (Latching, Dual Coil), must operate voltage (6.75 VDC), mounting type (Through Hole), and termination style (PC Pin). These parameters ensure direct functional substitution in existing circuit designs.

Enhanced Specifications: The substitute part provides superior performance characteristics including higher contact rating (2A vs 1A), increased switching voltage capability (250VAC/220VDC vs 125VAC/110VDC), lower coil current draw (15.6 mA vs 22.2 mA), and extended operating temperature range (-40°C ~ 85°C vs -40°C ~ 70°C). These enhancements represent improvements over the original design without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the V23079B1206B301 directly replace the TN2-L2-9V in existing designs?

A: Yes. Both relays share identical coil voltage, contact form, coil type, must operate voltage, mounting type, and termination style. Direct substitution is functionally equivalent.

Q: What are the key differences between these two relays?

A: The primary differences are contact rating (2A vs 1A), switching voltage (250VAC/220VAC vs 125VAC/110VDC), coil current (15.6 mA vs 22.2 mA), operating temperature range (-40°C ~ 85°C vs -40°C ~ 70°C), and coil resistance (578 Ohms vs 405 Ohms). The substitute part offers enhanced performance specifications.

Q: Are there any compatibility concerns with the higher contact rating of the substitute?

A: No. A higher contact rating indicates the substitute can safely handle greater current loads. This represents a capability improvement and does not create incompatibility with circuits designed for the original 1A rating.

Q: Does the substitute part have the same packaging?

A: The TN2-L2-9V uses standard through-hole packaging, while the V23079B1206B301 is supplied in tube packaging. Both use identical PC pin termination and through-hole mounting, ensuring PCB compatibility.

Q: What is the impact of the lower coil current in the substitute part?

A: The V23079B1206B301 requires 15.6 mA compared to the original 22.2 mA. This represents reduced power consumption in the coil circuit, which is a beneficial characteristic that does not affect functional compatibility.

Q: Are both parts classified under the same regulatory categories?

A: Yes. Both relays share identical ECCN (EAR99) and HTSUS (8536.41.0020) classifications. The substitute part is additionally RoHS Compliant.
