G2-DB01-SR Equivalent & Substitute Parts

Part Overview

The G2-DB01-SR is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NC (1 Form B) dual-channel device in 8-SMD surface mount packaging. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The G2-DB01-SR operates with a 1.2VDC input, supports load voltages from 0V to 350V, and handles a maximum load current of 170mA with an on-state resistance of 20 ohms maximum.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G2-DB01-SR is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPST-NC (1 Form B) x 2 dual-channel topology
• Package type: 8-SMD (0.300", 7.62mm) with gull wing termination
• Output capability: AC and DC load support
• Mounting method: Surface mount

Allowable Parameter Variations:

• Input voltage: Substitute must operate at or below the original 1.2VDC specification
• Load voltage range: Substitute must support the full 0V to 350V range or higher
• Load current: Substitute must handle the 170mA requirement or higher
• On-state resistance: Substitute must not exceed 20 ohms maximum

The AQW454A and AQW454AZ from Panasonic Electric Works meet all critical matching parameters. Both devices feature identical SPST-NC dual-channel configuration, 8-SMD gull wing packaging, and AC/DC output capability. The AQW454 series operates at 1.14VDC input (within tolerance), supports 0V to 400V load voltage (exceeds requirement), and handles 120mA load current with 16 ohms maximum on-state resistance. These specifications satisfy the substitution criteria for the obsolete G2-DB01-SR.

Parameter Comparison

Engineering Selection Recommendations

Both AQW454A and AQW454AZ are active production components from Panasonic Electric Works, providing long-term supply continuity compared to the obsolete G2-DB01-SR. The AQW454A is supplied in tube packaging, while the AQW454AZ is supplied in tape and reel format. Selection between these two variants depends on procurement and assembly requirements rather than electrical performance, as both devices are electrically identical.

The AQW454 series demonstrates superior compliance status. Both variants are RoHS compliant, whereas the original G2-DB01-SR compliance information is not specified. The Panasonic devices carry REACH Unaffected status matching the original part.

Load current capacity represents the primary electrical difference: the G2-DB01-SR supports 170mA while the AQW454 series supports 120mA. Applications requiring the full 170mA load current cannot use these substitutes. For applications operating below 120mA, the AQW454 series provides direct functional replacement with improved on-state resistance (16 ohms versus 20 ohms) and extended load voltage range (400V versus 350V).

Frequently Asked Questions (FAQ)

Q: Can the AQW454A or AQW454AZ directly replace the G2-DB01-SR in all applications?

A: Direct replacement is possible only in applications where the load current does not exceed 120mA. The G2-DB01-SR supports 170mA maximum load current, while the AQW454 series supports 120mA. Verify your application's actual load current requirement before substitution.

Q: What is the difference between AQW454A and AQW454AZ?

A: Both devices are electrically identical. The AQW454A is supplied in tube packaging, while the AQW454AZ is supplied in tape and reel format. Selection depends on your assembly process and procurement workflow.

Q: Are the package dimensions identical between the G2-DB01-SR and AQW454 series?

A: Yes. Both the original and substitute parts use 8-SMD (0.300", 7.62mm) packaging with gull wing termination. PCB footprints are compatible without modification.

Q: Does the AQW454 series support the same input voltage as the G2-DB01-SR?

A: The G2-DB01-SR operates at 1.2VDC input, while the AQW454 series operates at 1.14VDC input. This 0.06VDC difference is within typical circuit tolerance and does not affect functional compatibility in standard applications.

Q: What is the load voltage range difference?

A: The G2-DB01-SR supports 0V to 350V load voltage, while the AQW454 series supports 0V to 400V. The substitute provides extended voltage capability, making it suitable for all applications within the original specification range.

Q: Are there any compliance or regulatory differences?

A: The AQW454 series is RoHS compliant, providing improved environmental compliance compared to the original G2-DB01-SR. Both the original and substitute parts maintain REACH Unaffected status.
