Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF2E-L2-DC9V is determined by the following critical parameters:

• Coil voltage: 9VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pin (exact match required)
• Coil type: Latching, Dual Coil (exact match required)

Substitute parts must maintain compatibility across these core electrical and mechanical specifications. Contact rating, switching voltage, and operating temperature may vary within acceptable engineering tolerances, provided the substitute meets or exceeds the original part's performance envelope.

Parameter Comparison

Engineering Selection Recommendations

TQ2-L2-9V is the primary direct substitute for the DF2E-L2-DC9V. Both parts are manufactured by Panasonic Electric Works and share identical electrical specifications including coil voltage, contact form, contact rating, coil current, and coil resistance. The TQ2-L2-9V is classified as active product status, ensuring long-term availability and supply chain continuity. This part maintains the same operating temperature range and MSL rating as the original.

V23079B1206B301 is a compatible alternative manufactured by TE Connectivity Potter & Brumfield Relays. This part exceeds the original specifications in contact rating (2A versus 1A), switching voltage (250VAC/220VDC versus 125VAC/60VDC), and operating temperature range (-40°C to 85°C versus -40°C to 70°C). The V23079B1206B301 features lower coil current (15.6 mA versus 22.2 mA) and higher coil resistance (578 Ohms versus 405 Ohms), which may require circuit evaluation for drive compatibility. This part is RoHS compliant and active in production.

Selection between TQ2-L2-9V and V23079B1206B301 depends on circuit requirements. For direct replacement with minimal design changes, TQ2-L2-9V is preferred. For applications requiring enhanced contact rating or extended temperature operation, V23079B1206B301 provides additional performance margin.

Frequently Asked Questions (FAQ)

Q: Can the TQ2-L2-9V directly replace the DF2E-L2-DC9V without circuit modifications?

A: Yes. The TQ2-L2-9V maintains identical coil voltage, contact form, contact rating, coil current, and coil resistance specifications. No circuit modifications are required for direct substitution.

Q: What are the key differences between TQ2-L2-9V and V23079B1206B301?

A: The TQ2-L2-9V is a direct electrical equivalent with identical specifications. The V23079B1206B301 offers higher contact rating (2A), higher switching voltage capability (250VAC/220VDC), extended operating temperature range (-40°C to 85°C), and lower coil current (15.6 mA). The V23079B1206B301 has higher coil resistance (578 Ohms), which may affect drive circuit compatibility.

Q: Is the V23079B1206B301 suitable for applications requiring the original 1A contact rating?

A: Yes. The V23079B1206B301 contact rating of 2A exceeds the 1A requirement, providing additional safety margin. The part is suitable for applications designed for 1A operation.

Q: What is the impact of different coil resistance values on circuit design?

A: The DF2E-L2-DC9V and TQ2-L2-9V both have 405 Ohms coil resistance. The V23079B1206B301 has 578 Ohms coil resistance, resulting in lower coil current draw (15.6 mA versus 22.2 mA). Existing drive circuits designed for 22.2 mA may require evaluation to confirm adequate drive capability for the higher resistance coil.

Q: Are all substitute parts available in the same packaging format?

A: The DF2E-L2-DC9V packaging is not specified in available data. The TQ2-L2-9V is supplied in tube packaging. The V23079B1206B301 is supplied in tube packaging. Verify packaging requirements for your procurement process.

Q: What compliance certifications apply to these parts?

A: All three parts carry ECCN EAR99 classification and MSL 1 (Unlimited) rating. The TQ2-L2-9V and DF2E-L2-DC9V are REACH Unaffected. The V23079B1206B301 is RoHS compliant.
