TQ2SL-L-9V Equivalent & Substitute Parts

Part Overview

The TQ2SL-L-9V is an active telecom relay manufactured by Panasonic Electric Works, designed for surface mount applications requiring DPDT (2 Form C) switching functionality at 9VDC coil voltage. This component is a latching, single-coil relay with 2A contact rating, suitable for telecommunications and industrial control circuits. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives that maintain equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The TQ2SL-L-9V can be substituted with TE Connectivity Potter & Brumfield Relays part number 6-1462037-4 based on the following critical parameters that determine functional equivalence:

• Coil voltage: Both operate at 9VDC with identical must-operate voltage of 6.75 VDC
• Contact configuration: Both provide DPDT (2 Form C) switching
• Contact rating: Both rated for 2 A continuous current
• Mounting technology: Both are surface mount with gull wing termination
• Coil type: Both are latching, single-coil designs
• Operating temperature: Both function across -40°C to 85°C
• Relay classification: Both are telecom-grade relays
• Regulatory compliance: Both are RoHS compliant

Differences in coil current, coil resistance, switching voltage maximum, operate/release time, contact material composition, and seal rating do not prevent substitution when the application requirements fall within the specified operating parameters of both components.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-L-9V and 6-1462037-4 are active products with current manufacturing status and full regulatory compliance. The TQ2SL-L-9V is RoHS compliant, while the 6-1462037-4 meets the more stringent ROHS3 standard. Both components carry EAR99 export classification and identical HTSUS codes, confirming their functional equivalence for tariff and regulatory purposes.

Selection between these parts should be based on packaging requirements and inventory availability. The TQ2SL-L-9V is supplied in tube packaging, while the 6-1462037-4 is supplied in tape and reel format. The 6-1462037-4 features hermetic sealing, which provides enhanced environmental protection compared to the TQ2SL-L-9V. The TE Connectivity part exhibits faster switching response (3 ms operate and release time versus 4 ms), which may be advantageous in time-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 6-1462037-4 directly replace the TQ2SL-L-9V in existing designs?

A: Yes. Both relays share identical coil voltage (9VDC), contact configuration (DPDT), current rating (2A), mounting technology (surface mount gull wing), and operating temperature range (-40°C to 85°C). The electrical and mechanical interfaces are compatible.

Q: What is the difference in coil current between these parts?

A: The TQ2SL-L-9V draws 7.8 mA while the 6-1462037-4 draws 11.1 mA. This difference reflects different coil resistance values (1.16 kOhms versus 810 Ohms). Circuit designs must accommodate the higher current draw of the TE Connectivity part.

Q: Does the faster switching time of the 6-1462037-4 affect compatibility?

A: The 6-1462037-4 operates and releases in 3 ms compared to 4 ms for the TQ2SL-L-9V. This faster response is not a compatibility issue; it represents improved performance. Applications designed for 4 ms switching will function correctly with 3 ms switching.

Q: What is the significance of the hermetic seal on the 6-1462037-4?

A: Hermetic sealing provides protection against moisture ingress and environmental contamination. This feature enhances reliability in humid or corrosive environments but is not required for standard indoor applications.

Q: How do the packaging formats affect component selection?

A: The TQ2SL-L-9V is supplied in tube packaging suitable for manual assembly or small-volume production. The 6-1462037-4 is supplied in tape and reel format optimized for automated pick-and-place assembly. Selection depends on manufacturing process requirements and volume.

Q: Are both parts RoHS compliant?

A: Yes. The TQ2SL-L-9V is RoHS compliant. The 6-1462037-4 meets ROHS3, which is a more recent and stringent standard. Both are suitable for applications requiring RoHS compliance.

Q: What is the maximum switching voltage for each part?

A: The TQ2SL-L-9V is rated for 125VAC and 220VDC maximum switching voltage. The 6-1462037-4 is rated for 250VAC and 220VDC maximum. The TE Connectivity part provides higher AC voltage capability.
