Equivalent & Substitute Parts for TF2-5V

Part Overview

The Panasonic Electric Works TF2-5V is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 1A at 5VDC coil voltage. This through-hole mounted relay is designed for general switching applications with sealed construction and silver/gold contact materials. The TF2-5V is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TF2-5V is determined by the following critical parameters:

Mandatory Matching Parameters:

• Contact Form: DPDT (2 Form C)
• Contact Rating (Current): 1 A
• Coil Voltage: 5VDC
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -40°C ~ 70°C
• Switching Voltage: 125VAC, 110VDC - Max

Compatible Substitute Parts:

The TQ2-5V qualifies as a direct substitute. Both parts share identical electrical specifications for coil voltage (5VDC), contact form (DPDT), current rating (1A), switching voltage limits, operating temperature range, and through-hole PC pin termination. The TQ2-5V is manufactured by the same supplier (Panasonic Electric Works) and maintains functional equivalence for circuit-level replacement.

The TQ2-12V does not qualify as a substitute due to different coil voltage specification (12VDC vs. 5VDC), which would require circuit redesign and different power supply requirements.

Parameter Comparison

Engineering Selection Recommendations

The TQ2-5V is the qualified substitute for the obsolete TF2-5V. Both relays maintain electrical and mechanical compatibility across all critical parameters: identical coil voltage (5VDC), contact configuration (DPDT 1A), switching voltage ratings, operating temperature range, and through-hole PC pin termination.

The TQ2-5V offers the advantage of active product status, ensuring continued availability and supply chain reliability. The TQ2-5V is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the TF2-5V compliance status is not specified.

Performance differences exist in coil current (28.1 mA vs. 16 mA) and switching speed (3 ms vs. 4 ms for both operate and release times). These differences do not affect functional substitution in standard switching applications but should be evaluated in designs with specific power budget or timing-critical requirements.

Frequently Asked Questions (FAQ)

Q: Can the TQ2-5V directly replace the TF2-5V in existing circuit boards?

A: Yes. The TQ2-5V maintains identical coil voltage (5VDC), contact form (DPDT), current rating (1A), switching voltage limits, operating temperature range, and through-hole PC pin termination. No circuit modifications are required for functional replacement.

Q: What are the differences between the TF2-5V and TQ2-5V?

A: The primary differences are product classification (General Purpose vs. Telecom relay), coil current draw (16 mA vs. 28.1 mA), switching speed (4 ms vs. 3 ms), and product status (Obsolete vs. Active). The TQ2-5V is ROHS3 compliant. All critical electrical and mechanical parameters remain identical.

Q: Why is the TQ2-12V not a suitable substitute?

A: The TQ2-12V operates at 12VDC coil voltage, whereas the TF2-5V requires 5VDC. This fundamental difference requires circuit redesign and different power supply configuration. Coil voltage is a non-negotiable substitution parameter.

Q: What is the packaging difference between substitute parts?

A: The TF2-5V packaging is specified as "-" (not detailed). The TQ2-5V is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are there compliance or regulatory considerations for substitution?

A: The TQ2-5V is ROHS3 compliant and REACH unaffected. The TF2-5V compliance status is not specified. If your application requires documented ROHS3 compliance, the TQ2-5V meets this requirement.
