Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SL-1.5V-Z is determined by strict equivalence across the following critical parameters:

Coil voltage (1.5VDC), contact form (DPDT), contact current rating (2A), switching voltage specification (125VAC, 220VDC - Max), coil current (93.8 mA), non-latching coil type, surface mount configuration, gull wing termination, operating temperature range (-40°C ~ 85°C), coil resistance (16 Ohms), must-operate and must-release voltage thresholds, switching time specifications (4 ms operate/release), contact material composition (Silver Nickel/Gold), and telecom relay classification.

The TQ2SA-1.5V-Z qualifies as a parametric equivalent substitute based on complete alignment with all specified electrical and mechanical parameters within the TQ-SMD series.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-1.5V-Z and TQ2SA-1.5V-Z maintain active product status with RoHS compliance certification. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical differentiation. The TQ2SA-1.5V-Z currently maintains higher inventory levels (1125 pcs vs. 984 pcs), which may influence procurement decisions for high-volume applications. Both components are suitable for direct substitution in telecommunications relay applications requiring 1.5VDC coil voltage, DPDT switching configuration, and 2A contact rating.

Frequently Asked Questions (FAQ)

Q: Can the TQ2SA-1.5V-Z replace the TQ2SL-1.5V-Z in existing circuit designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, contact configuration, coil voltage, current ratings, switching characteristics, and operating temperature range. No circuit modifications are required.

Q: Are there differences in contact material or reliability between these substitutes?

A: No. Both parts use identical Silver Nickel (AgNi) and Gold (Au) contact materials, ensuring equivalent contact performance and longevity.

Q: Do both parts support the same mounting and packaging requirements?

A: Yes. Both the TQ2SL-1.5V-Z and TQ2SA-1.5V-Z feature surface mount configuration with gull wing termination and Tape & Reel packaging, enabling direct PCB assembly compatibility.

Q: What is the significance of the base product numbers (TQ2SL vs. TQ2SA)?

A: The base product numbers indicate different part variants within the TQ-SMD series. However, when all electrical and mechanical parameters are identical, these variants are functionally interchangeable for the specified application.

Q: Are both parts RoHS compliant?

A: Yes. Both the TQ2SL-1.5V-Z and TQ2SA-1.5V-Z carry RoHS compliance certification, meeting environmental and regulatory requirements for telecommunications applications.
