Substitute Part Grouping Explanation

Substitute parts for TQ2SS-3V-Y are grouped strictly by identical electrical, mechanical, and operational parameters:

• Surface mount type and gull wing termination
• DPDT (2 Form C) contact configuration
• 3VDC coil voltage, 46.7 mA coil current, and 64.3 Ohms coil resistance
• 2A contact rating and maximum switching voltages (125VAC, 220VDC)
• Identical operate and release times of 4 ms
• Matching operating temperature range (-40°C ~ 85°C)
• Silver Nickel (AgNi), Gold (Au) contact material

Only parts meeting these criteria, as provided, can be considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

When selecting between TQ2SS-3V-Y and TQ2SA-3V-Z, reference the provided product status (active for both) and compliance data. TQ2SA-3V-Z is explicitly listed as ROHS3 compliant and REACH unaffected. Both are suitable for surface mount applications requiring gull wing termination, DPDT relay configuration, and identical electrical ratings.

The only mechanical distinction is packaging: TQ2SS-3V-Y is supplied in bulk, whereas TQ2SA-3V-Z is supplied in tape & reel format, advantageous for automated assembly processes without affecting the functional equivalence or electrical rating.

Frequently Asked Questions (FAQ)

Q1: Are TQ2SS-3V-Y and TQ2SA-3V-Z directly interchangeable in circuit design?
A1: Yes. Both parts share identical electrical, mechanical, and operational parameters, with only packaging differences.

Q2: What are the main differences in packaging and why does it matter?
A2: TQ2SS-3V-Y is available in bulk packaging. TQ2SA-3V-Z is supplied in tape & reel, suited to automated pick-and-place assembly lines.

Q3: Does the RoHS/REACH status impact component selection?
A3: TQ2SA-3V-Z is RoHS3-compliant and REACH-unaffected. TQ2SS-3V-Y does not specify status in the provided parameters. Choose based on regulatory compliance requirements.

Q4: Do both relays meet the same performance and reliability standards?
A4: Both relays are listed as active and have approval agency recognition (CSA, UR for TQ2SS-3V-Y). All specified operational ratings are matched.

Q5: Can inventory decisions be made solely on these substitution criteria?
A5: Yes. Electrical and mechanical equivalence is fully supported by the provided parameters. Packaging may be a consideration for production logistics.
