TQ2SS-L-1.5V Equivalent & Substitute Parts

Part Overview

The TQ2SS-L-1.5V is an active telecom relay manufactured by Panasonic Electric Works, configured as a DPDT (2 Form C) surface mount component with 2A contact rating and 1.5VDC coil voltage. This relay is designed for telecommunications applications requiring latching, single-coil operation with gull wing termination. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component alternatives that maintain functional and electrical compatibility.

• Contact rating is equivalent at 2 A
• Mounting type is identical: Surface Mount
• Termination style matches: Gull Wing
• Coil type is identical: Latching, Single Coil
• Operating temperature range is identical: -40°C ~ 85°C
• Must operate voltage is identical: 1.13 VDC
• Relay type classification is identical: Telecom

These parameters define the functional and electrical compatibility boundaries for substitution within this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SS-L-1.5V and 5-1462037-1 maintain active product status with current manufacturing support. The TQ2SS-L-1.5V carries RoHS Compliant certification, while the 5-1462037-1 carries ROHS3 Compliant certification, indicating both parts meet current environmental compliance requirements. The substitute part 5-1462037-1 provides hermetically sealed construction with enhanced contact material composition (Palladium, Ruthenium, Gold), faster switching response (3 ms operate and release time versus 4 ms), and higher maximum switching voltage rating (250VAC versus 125VAC). Selection between these parts should be based on application-specific requirements for switching voltage, coil current tolerance, and packaging format (Tube versus Cut Tape).

Frequently Asked Questions (FAQ)

Q: Can 5-1462037-1 directly replace TQ2SS-L-1.5V in existing designs?

A: Yes, provided the application requirements fall within the specified parameters. Both parts share identical coil voltage (1.5VDC), contact form (DPDT), contact rating (2A), mounting type (Surface Mount), termination style (Gull Wing), operating temperature range (-40°C ~ 85°C), and must operate voltage (1.13VDC). Differences in coil current (46.9 mA versus 66.7 mA), coil resistance (32 Ohms versus 23 Ohms), and switching voltage ratings must be evaluated against circuit design specifications.

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

A: The primary differences are coil current draw (5-1462037-1 draws 66.7 mA versus 46.9 mA for TQ2SS-L-1.5V), switching voltage maximum rating (5-1462037-1 rated to 250VAC versus 125VAC), switching speed (5-1462037-1 operates and releases in 3 ms versus 4 ms), seal rating (5-1462037-1 is hermetically sealed), contact material composition, and packaging format (Cut Tape versus Tube).

Q: Are there packaging considerations for substitution?

A: Yes. The TQ2SS-L-1.5V is supplied in Tube packaging, while 5-1462037-1 is supplied in Cut Tape (CT) format. Assembly processes and component handling equipment must accommodate the applicable packaging format.

Q: Do both parts meet current compliance standards?

A: Yes. The TQ2SS-L-1.5V is RoHS Compliant, and 5-1462037-1 is ROHS3 Compliant. Both parts carry EAR99 ECCN classification and 8536.41.0020 HTSUS code.
