TQ2SL-L-1.5V Equivalent & Substitute Parts

Part Overview

The TQ2SL-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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SL-L-1.5V is determined by the following critical parameters:

• Coil voltage matching at 1.5VDC
• Contact form configuration as DPDT (2 Form C)
• Contact current rating of 2 A minimum
• Surface mount mounting type with gull wing termination
• Operating temperature range of -40°C ~ 85°C
• Must operate voltage of 1.13 VDC or lower
• Latching, single-coil operation

The substitute part 5-1462037-1 (TE Connectivity Potter & Brumfield Relays) satisfies all critical substitution criteria. Both parts operate at identical coil voltage, contact form, current rating, mounting configuration, and temperature specifications. Functional equivalence is established through matching electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-L-1.5V and 5-1462037-1 maintain active product status with current manufacturing support. The TQ2SL-L-1.5V is RoHS Compliant, while the 5-1462037-1 is ROHS3 Compliant, indicating both parts meet current environmental and regulatory requirements. Both parts carry EAR99 ECCN classification and identical HTSUS codes (8536.41.0020).

The 5-1462037-1 offers higher switching voltage capability (250VAC versus 125VAC) and faster switching times (3 ms operate/release versus 4 ms), with hermetic sealing providing enhanced environmental protection. The TQ2SL-L-1.5V features lower coil current consumption (46.9 mA versus 66.7 mA), which may be advantageous in power-constrained applications.

Selection between these parts should be based on specific application requirements regarding switching voltage, coil power consumption, switching speed, and environmental sealing needs. Both parts are functionally equivalent for standard telecom relay applications operating within the specified parameters.
