TQ2SL-9V Equivalent & Substitute Parts

Part Overview

The TQ2SL-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 in compact surface mount packages. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TQ2SL-9V are identified based on strict electrical and mechanical parameter alignment. The critical parameters determining substitutability are:

• Coil voltage: 9VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A minimum
• Coil current: 15.5 mA
• Coil resistance: 579 Ohms
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Operating temperature range: -40°C ~ 85°C minimum
• Coil type: Non Latching

Two substitute parts meet these criteria:

TQ2SA-9V (Panasonic Electric Works) — Parametric equivalent with identical electrical specifications and coil characteristics. Differs only in base product number and RoHS certification level (ROHS3 vs. RoHS Compliant).

IM05GR (TE Connectivity Potter & Brumfield Relays) — Similar substitute with matching core electrical parameters. Operates at faster switching speeds (3 ms vs. 4 ms) and includes hermetic sealing. Maximum switching voltage is higher (250VAC vs. 125VAC). Contact material composition differs (Palladium/Ruthenium/Gold vs. Silver Nickel/Gold).

Parameter Comparison

Engineering Selection Recommendations

TQ2SA-9V is the primary parametric equivalent for direct replacement. Both parts are manufactured by Panasonic Electric Works with identical electrical and mechanical specifications. TQ2SA-9V carries ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory alignment for applications requiring stricter environmental standards.

IM05GR serves as an alternative substitute when enhanced switching performance or higher AC voltage capability is required. The 1 ms faster switching response (3 ms vs. 4 ms) and hermetic sealing provide advantages in noise-sensitive or harsh environment applications. The higher maximum AC switching voltage (250VAC vs. 125VAC) accommodates designs with elevated AC load requirements. Selection of IM05GR requires confirmation that the different contact material composition (Palladium/Ruthenium/Gold) is compatible with the intended load characteristics.

All three parts maintain active product status and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can TQ2SA-9V replace TQ2SL-9V in existing designs?

A: Yes. TQ2SA-9V is a parametric equivalent with identical coil voltage, contact form, current rating, coil current, coil resistance, and switching characteristics. Both parts are surface mount with gull wing termination and operate across the same temperature range.

Q: What are the key differences between TQ2SL-9V and IM05GR?

A: IM05GR operates 1 ms faster in both operate and release times (3 ms vs. 4 ms). It supports higher maximum AC switching voltage (250VAC vs. 125VAC) and includes hermetic sealing. Contact material differs: IM05GR uses Palladium/Ruthenium/Gold versus TQ2SL-9V's Silver Nickel/Gold composition. All other electrical parameters remain equivalent.

Q: Does packaging format affect substitutability?

A: Packaging format (Tube vs. Cut Tape) does not affect electrical or mechanical substitutability. Selection depends on assembly process requirements and inventory management practices. TQ2SL-9V and TQ2SA-9V are supplied in Tube packaging; IM05GR is supplied in Cut Tape format.

Q: Are all substitute parts RoHS compliant?

A: Yes. TQ2SL-9V is RoHS Compliant. TQ2SA-9V and IM05GR are both ROHS3 Compliant, meeting the most current RoHS standards.

Q: Which substitute should be selected for high-speed switching applications?

A: IM05GR is the appropriate choice for applications requiring faster switching response. Its 3 ms operate and release times provide 1 ms improvement over both TQ2SL-9V and TQ2SA-9V.
