Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-L-3V-Z and 5-1462037-4 are active products with current manufacturing status. The TQ2SL-L-3V-Z carries RoHS compliance certification, while the 5-1462037-4 carries ROHS3 compliance and REACH unaffected status. Both parts meet the mandatory electrical and mechanical parameters required for telecom relay applications with 3VDC coil voltage, DPDT contact configuration, and 2A contact rating.

The 5-1462037-4 offers hermetically sealed construction with enhanced switching voltage capability (250VAC maximum versus 125VAC), faster switching times (3 ms operate and release versus 4 ms), and higher coil current draw (33.3 mA versus 23.3 mA). The TQ2SL-L-3V-Z provides lower coil current consumption and higher coil resistance (129 Ohms versus 90 Ohms).

Selection between these parts depends on specific application requirements regarding power consumption, switching speed, and environmental sealing needs, with both meeting the core functional and compliance criteria for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5-1462037-4 directly replace the TQ2SL-L-3V-Z in existing designs?

A: Yes. Both parts share identical coil voltage (3VDC), contact form (DPDT), contact rating (2A), mounting type (surface mount), coil type (latching, single coil), termination style (gull wing), operating temperature range (-40°C to 85°C), and must operate voltage (2.25VDC). These parameters determine functional compatibility for telecom relay applications.

Q: What are the differences in switching performance between these parts?

A: The 5-1462037-4 operates and releases 1 millisecond faster than the TQ2SL-L-3V-Z (3 ms versus 4 ms). This difference may be significant in time-critical switching applications.

Q: How do the coil current specifications differ?

A: The TQ2SL-L-3V-Z draws 23.3 mA coil current, while the 5-1462037-4 draws 33.3 mA. Applications with strict power budget constraints should account for this 10 mA difference in design calculations.

Q: What packaging options are available for each part?

A: The TQ2SL-L-3V-Z is supplied in tape & reel (TR) packaging. The 5-1462037-4 is available in cut tape (CT) and Digi-Reel® packaging. Packaging selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Are there compliance differences between these parts?

A: The TQ2SL-L-3V-Z is RoHS compliant. The 5-1462037-4 is ROHS3 compliant and carries REACH unaffected status. Both meet current environmental compliance standards for their respective markets.

Q: What is the difference in contact material composition?

A: The TQ2SL-L-3V-Z uses silver nickel (AgNi) and gold (Au) contact materials. The 5-1462037-4 uses palladium (Pd), ruthenium (Ru), and gold (Au). Contact material selection affects long-term reliability in specific chemical and environmental conditions.

Q: Does the hermetic sealing of the 5-1462037-4 provide advantages?

A: The 5-1462037-4 is hermetically sealed, providing enhanced protection against moisture and environmental contamination. The TQ2SL-L-3V-Z seal rating is not specified. Hermetic sealing is beneficial for applications requiring extended operational life in harsh or humid environments.
