TQ2SS-9V Equivalent & Substitute Parts

Part Overview

The TQ2SS-9V 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 9VDC coil voltage. This relay is designed for telecommunications applications requiring dual-pole, dual-throw switching functionality. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

TQ2SA-9V (Parametric Equivalent): The TQ2SA-9V is a parametric equivalent to the TQ2SS-9V, manufactured by Panasonic Electric Works within the same TQ-SMD series. All critical electrical parameters match exactly, including coil voltage, contact configuration, current rating, and switching characteristics. The TQ2SA-9V carries ROHS3 compliance status, representing enhanced regulatory compliance compared to the base RoHS designation of the TQ2SS-9V. This part is suitable for direct substitution in applications where the TQ2SS-9V is specified.

IM05GR (Similar Equivalent): The IM05GR, manufactured by TE Connectivity Potter & Brumfield Relays, meets all critical electrical parameters required for substitution. Key differences include enhanced switching voltage capability (250VAC maximum versus 125VAC), faster switching response (3 ms operate/release time versus 4 ms), hermetic sealing, and alternative contact material composition. The IM05GR carries ROHS3 compliance and REACH Unaffected status. This part is suitable for applications where enhanced environmental protection and faster switching response are acceptable or beneficial.

Frequently Asked Questions (FAQ)

Q: Can TQ2SA-9V be used as a direct replacement for TQ2SS-9V? A: Yes. The TQ2SA-9V matches all critical electrical and mechanical parameters of the TQ2SS-9V, including coil voltage, contact form, current rating, switching characteristics, and operating temperature range. Both parts are manufactured by Panasonic Electric Works and are compatible with identical circuit designs.

Q: What are the key differences between TQ2SS-9V and IM05GR? A: The IM05GR provides higher switching voltage capability (250VAC versus 125VAC), faster switching response (3 ms versus 4 ms), and hermetic sealing. Contact material composition differs, with IM05GR using Palladium, Ruthenium, and Gold versus Silver Nickel and Gold in the TQ2SS-9V. All other critical parameters remain identical.

Q: Are there packaging differences between substitute parts? A: Yes. The TQ2SS-9V and TQ2SA-9V are supplied in Tube packaging, while the IM05GR is supplied in Cut Tape (CT) format. Both packaging formats are standard for surface mount components and do not affect electrical compatibility.

Q: Do all substitute parts meet RoHS compliance? A: The TQ2SS-9V is RoHS Compliant. Both TQ2SA-9V and IM05GR carry ROHS3 Compliant status, representing enhanced compliance standards. All parts are suitable for applications requiring RoHS compliance.

Q: Which substitute part should be selected for enhanced environmental protection? A: The IM05GR features hermetic sealing, providing enhanced protection against moisture and environmental contamination compared to the TQ2SS-9V and TQ2SA-9V. Selection depends on application environmental requirements.

Q: Are the coil resistance values identical across all parts? A: Yes. All three parts (TQ2SS-9V, TQ2SA-9V, and IM05GR) have identical coil resistance of 579 Ohms, ensuring equivalent circuit behavior and drive requirements.
