Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TQ2SL-4.5V-X is determined by strict equivalence across the following critical parameters:

Coil voltage specification (4.5VDC), contact configuration (DPDT with 2 Form C), current rating (2A), switching voltage capability (125VAC, 220VDC maximum), coil current draw (31 mA), surface mount packaging with gull wing termination, operating temperature range (-40°C to 85°C), and coil resistance (145 Ohms). All substitute parts must maintain identical values across these parameters to ensure functional compatibility without circuit redesign or validation testing.

Parameter Comparison

Engineering Selection Recommendations

Both the TQ2SL-4.5V-X and TQ2SA-4.5V-Z maintain active product status with full regulatory compliance. The TQ2SA-4.5V-Z carries ROHS3 compliance certification and REACH unaffected status, providing enhanced environmental and regulatory documentation. Selection between these parts should be based on inventory availability and specific compliance documentation requirements for the end application. Both parts are functionally equivalent for telecom relay applications requiring DPDT switching at 4.5VDC with 2A contact rating.

Frequently Asked Questions (FAQ)

Q: Can TQ2SA-4.5V-Z directly replace TQ2SL-4.5V-X in existing designs?

A: Yes. Both parts maintain identical electrical specifications including coil voltage, contact configuration, current rating, switching voltage, and operating temperature range. Surface mount gull wing termination is identical, enabling direct PCB placement without modification.

Q: What are the key differences between these substitute parts?

A: The primary differences are the base product numbers (TQ2SL versus TQ2SA) and regulatory compliance documentation. TQ2SA-4.5V-Z carries ROHS3 compliance and REACH unaffected status, while TQ2SL-4.5V-X is RoHS compliant. All electrical and mechanical parameters are equivalent.

Q: Are there packaging differences between these relays?

A: Both parts are supplied in Tape & Reel (TR) packaging for surface mount assembly. Termination style, mounting type, and footprint are identical.

Q: What parameters must remain constant for substitution eligibility?

A: Coil voltage (4.5VDC), contact form (DPDT), current rating (2A), switching voltage (125VAC/220VDC), coil current (31 mA), mounting type (surface mount), termination style (gull wing), operating temperature range (-40°C to 85°C), and coil resistance (145 Ohms) must all match exactly.
