Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF2E-L2-DC6V is determined by the following critical parameters:

• Coil Voltage: Must be 6VDC to ensure direct compatibility with existing power supply circuits
• Contact Form: Must be DPDT (2 Form C) to maintain switching functionality
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Termination Style: Must be PC Pin for direct connection to printed circuit boards
• Coil Type: Must be latching, dual coil to preserve operational behavior

The V23079B1202B301 from TE Connectivity Potter & Brumfield Relays meets all critical substitution criteria. While this substitute exhibits higher contact rating (2A versus 1A) and improved switching voltage specifications, these enhancements provide additional design margin without compromising compatibility with the original application requirements.

Engineering Selection Recommendations

The V23079B1202B301 is the qualified substitute for the DF2E-L2-DC6V. Selection rationale is based on the following factors:

• Product Status: The DF2E-L2-DC6V is obsolete, while the V23079B1202B301 maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance: The V23079B1202B301 is RoHS compliant, meeting current regulatory requirements for electronic component manufacturing and distribution
• Functional Compatibility: Both relays share identical coil voltage, contact form, mounting type, and termination style, enabling direct substitution without circuit redesign
• Enhanced Specifications: The substitute provides superior contact rating (2A), switching voltage capability (250VAC/220VDC), and extended operating temperature range (-40°C ~ 85°C), offering improved performance margins for the application

Frequently Asked Questions (FAQ)

Q: Can the V23079B1202B301 be used as a direct replacement for the DF2E-L2-DC6V?

A: Yes. Both relays operate at 6VDC, feature DPDT contact configuration, utilize through-hole mounting with PC pin termination, and employ latching dual-coil design. Direct substitution is possible without circuit modification.

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

A: The V23079B1202B301 provides higher contact current rating (2A versus 1A), increased switching voltage capability (250VAC/220VDC versus 125VAC/60VDC), lower coil current draw (23.3mA versus 33.3mA), and extended operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C). These differences represent performance enhancements rather than compatibility issues.

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

A: No. A relay with higher contact rating can safely handle lower current applications. The 2A rating of the V23079B1202B301 is fully compatible with circuits designed for the 1A DF2E-L2-DC6V.

Q: Are there packaging differences between these relays?

A: The DF2E-L2-DC6V uses standard through-hole packaging, while the V23079B1202B301 is supplied in tube packaging. Both maintain identical form factor and pin configuration for PCB mounting.

Q: Why is the substitute relay more efficient in terms of coil current?

A: The V23079B1202B301 has higher coil resistance (257 Ohms versus 180 Ohms), resulting in lower coil current draw (23.3mA versus 33.3mA) at the same 6VDC operating voltage. This represents improved power efficiency without affecting switching performance.

Q: Is the substitute suitable for applications requiring the full -40°C ~ 70°C temperature range?

A: Yes. The V23079B1202B301 operates across -40°C ~ 85°C, which encompasses the original specification range and provides additional thermal margin for demanding environments.
