Panasonic TN2-L2-6V General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The Panasonic TN2-L2-6V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 1A at 6VDC coil voltage. This is a through-hole mounted component with latching dual coil design and sealed construction. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the Panasonic TN2-L2-6V is determined by the following critical parameters:

• Coil voltage matching at 6VDC
• Contact form configuration as DPDT (2 Form C)
• Through-hole mounting with PC pin termination
• Latching dual coil operation
• Must operate voltage threshold of 4.5 VDC minimum

The TE Connectivity Potter & Brumfield V23079B1202B301 meets these core substitution criteria. While the substitute part offers higher contact current rating (2A vs 1A) and extended temperature range, these represent performance enhancements rather than deviations from the functional requirements of the original component.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity V23079B1202B301 is a direct functional substitute for the obsolete Panasonic TN2-L2-6V. Both components share identical coil voltage, contact configuration, mounting method, and operational thresholds. The substitute part is currently in active production status with RoHS compliance certification, providing supply chain continuity for legacy system support.

The V23079B1202B301 provides enhanced electrical performance through higher contact current rating and switching voltage capability, along with extended operating temperature range. These characteristics ensure compatibility with the original application while offering improved reliability margins. The slightly higher coil resistance and marginally longer switching times remain within acceptable operational parameters for general purpose relay applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity V23079B1202B301 directly replace the Panasonic TN2-L2-6V in existing PCB assemblies?

A: Yes. Both components use identical through-hole PC pin termination and share the same footprint configuration. No PCB modifications are required for substitution.

Q: What is the significance of the higher contact current rating (2A vs 1A) in the substitute part?

A: The substitute part is rated for twice the contact current capacity. This provides additional safety margin in applications operating at or near the original 1A specification. The substitute will not cause issues in circuits designed for 1A operation.

Q: Are there differences in coil drive requirements between these two relays?

A: The substitute part requires 23.3 mA coil current compared to 33.3 mA for the original. This represents a 30% reduction in coil power consumption. Existing drive circuits designed for the Panasonic part will operate the TE Connectivity substitute without modification, though with lower power draw.

Q: How do the switching time differences affect system performance?

A: The substitute part has 1 ms longer operate and release times (4 ms vs 3 ms). For general purpose relay applications, this difference is negligible and does not impact system functionality in standard switching circuits.

Q: What is the packaging difference between these parts?

A: The Panasonic TN2-L2-6V uses standard through-hole packaging. The TE Connectivity V23079B1202B301 is supplied in tube packaging. Both are suitable for manual or automated assembly processes.

Q: Is the RoHS compliance status relevant for substitution decisions?

A: The substitute part carries RoHS Compliant certification, meeting current environmental and regulatory requirements. This is advantageous for new designs and systems requiring compliance documentation.
