Key Parameters

Substitute Part Grouping Explanation

Substitution of the AX211030 is based on strict equivalence of the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain SPST-NO contact arrangement to preserve circuit logic and control functionality.

Switching Characteristics: The substitute must support the required switching current and voltage specifications. The AX211030 operates at 500mA DC and 100V DC within a 10VA power envelope.

Physical Form Factor: Through Hole mounting with Axial termination style ensures mechanical and electrical compatibility with existing printed circuit board layouts and assembly processes.

Temporal Performance: Operate time of 0.6 ms and Release time of 0.1 ms define the switching speed characteristics required for system timing and control response.

Environmental Compliance: RoHS3 compliance and MSL Level 1 rating ensure regulatory conformance and reliability in standard storage and handling conditions.

Thermal Operating Range: The -40°C to 125°C operating temperature range must be maintained or exceeded to ensure functionality across the intended application environment.

The substitute part SW GP560/20-25 AT from Standex-Meder Electronics meets all these critical parameters while offering enhanced current-carrying capacity and active product status.

Engineering Selection Recommendations

The SW GP560/20-25 AT from Standex-Meder Electronics is a direct functional substitute for the obsolete AX211030. Selection of this substitute is supported by the following engineering criteria:

Electrical Equivalence: All critical electrical parameters including switching voltage (100V DC), power rating (10VA), and switching timing characteristics (0.6 ms operate, 0.1 ms release) are identical. The substitute's enhanced current rating (1A versus 500mA) and AC/DC capability provide additional operational margin without introducing incompatibility.

Physical Compatibility: Identical physical dimensions, mounting type (Through Hole), and termination style (Axial) ensure direct replacement capability in existing circuit board layouts without modification to PCB artwork or assembly procedures.

Regulatory Compliance: Both components maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and reliability requirements for standard industrial and commercial applications.

Product Availability: The substitute part is classified as Active product status with substantial inventory availability (18,387 pieces), ensuring reliable supply for both immediate replacement needs and future production requirements.

Certification Status: The substitute carries REACH Unaffected status and EAR99 ECCN classification, confirming compliance with international trade and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the SW GP560/20-25 AT directly replace the AX211030 without circuit modification?

A: Yes. The SW GP560/20-25 AT is a direct pin-compatible and functionally equivalent substitute. Identical physical dimensions, mounting type, termination style, and all critical electrical parameters (switching voltage, power rating, timing characteristics) eliminate the need for circuit or PCB modifications.

Q: What is the significance of the higher current rating on the substitute part?

A: The SW GP560/20-25 AT is rated for 1A switching current compared to the AX211030's 500mA rating. This represents a 2x current margin and does not create incompatibility. The substitute operates safely at the original 500mA switching requirement while providing additional capacity for future design flexibility or higher-current applications.

Q: Are there any temperature or environmental limitations when substituting?

A: No. Both components operate across the identical temperature range (-40°C to 125°C) and maintain equivalent MSL Level 1 ratings. Environmental performance characteristics are equivalent.

Q: Why is the AX211030 listed as Obsolete?

A: The AX211030 is no longer in active production by Celduc Inc. The SW GP560/20-25 AT from Standex-Meder Electronics represents the current-production equivalent that fulfills the same functional and electrical requirements.

Q: Does the substitute support both AC and DC switching?

A: The SW GP560/20-25 AT is rated for AC/DC switching at 1A, whereas the AX211030 is specified for DC switching at 500mA. For applications requiring only DC operation at 500mA or less, the substitute's AC/DC capability introduces no incompatibility and provides additional operational flexibility.

Q: What is the packaging difference between these parts?

A: The AX211030 information does not specify packaging details. The SW GP560/20-25 AT is supplied in Bulk packaging. Confirm packaging requirements with your procurement or supply chain department for order specification.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant with MSL Level 1 ratings. The substitute additionally carries REACH Unaffected status and EAR99 ECCN classification, confirming full compliance with international environmental and trade regulations.
