Key Parameters

Substitute Part Grouping Explanation

The GM-FA-10J from Banner Engineering Corporation qualifies as a functional substitute based on the following critical parameters:

• Contact Form Match: Both parts provide DPST-NO (2 Form A) configuration, ensuring identical switching topology
• Coil Voltage Compatibility: The GM-FA-10J accepts 24VAC/DC input, which encompasses the SR231A00's 24VDC requirement
• DIN Rail Mounting: Both components use DIN Rail mounting, enabling direct mechanical replacement
• Screw Terminal Termination: Identical termination style allows direct wiring compatibility
• Lighted Indicator Feature: Both include lighted indicator functionality
• Contact Rating Sufficiency: The GM-FA-10J provides 6A contact rating, exceeding the SR231A00's 1.5A requirement, ensuring adequate current handling capacity

The GM-FA-10J represents an active product with current manufacturing status and enhanced electrical specifications compared to the obsolete SR231A00.

Parameter Comparison

Engineering Selection Recommendations

The GM-FA-10J is suitable for applications requiring SR231A00 replacement based on the following factors:

• Active Product Status: The GM-FA-10J maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The GM-FA-10J carries ROHS3 compliance certification, meeting current environmental and regulatory requirements
• Electrical Specification Enhancement: The 6A contact rating and 250VAC switching capability provide operational margin beyond the original SR231A00 specifications
• Mechanical Compatibility: Identical DIN Rail mounting and screw terminal configuration enable direct installation without mechanical redesign
• Operating Temperature Consideration: The GM-FA-10J operates within 0°C ~ 50°C range, which overlaps substantially with the SR231A00's -10°C ~ 55°C range; applications requiring operation below 0°C or above 50°C require alternative evaluation

Frequently Asked Questions (FAQ)

Q: Can the GM-FA-10J directly replace the SR231A00 in existing installations?

A: Yes. Both components share identical contact form (DPST-NO), mounting type (DIN Rail), termination style (Screw Terminal), and coil voltage compatibility (24VDC operation). Direct mechanical and electrical substitution is possible without circuit modification.

Q: What is the significance of the higher 6A contact rating on the GM-FA-10J compared to the SR231A00's 1.5A rating?

A: The GM-FA-10J's 6A rating exceeds the SR231A00's 1.5A requirement, providing additional current-handling capacity. This represents a specification enhancement that maintains backward compatibility with lower-current applications while enabling use in higher-current switching scenarios.

Q: Are there operating temperature limitations when substituting the GM-FA-10J for the SR231A00?

A: The GM-FA-10J operates within 0°C ~ 50°C, while the SR231A00 operates within -10°C ~ 55°C. Applications requiring operation below 0°C or above 50°C should be evaluated against the GM-FA-10J's temperature specifications before substitution.

Q: What is the significance of ROHS3 compliance on the GM-FA-10J?

A: ROHS3 compliance indicates the GM-FA-10J meets current environmental and hazardous substance restrictions applicable to electrical and electronic equipment. This certification is relevant for applications subject to regulatory compliance requirements.

Q: Does the GM-FA-10J's 24VAC/DC coil voltage specification affect compatibility with 24VDC circuits?

A: No. The GM-FA-10J's 24VAC/DC specification indicates the coil accepts both 24VAC and 24VDC input. The SR231A00 operates on 24VDC, which falls within the GM-FA-10J's acceptable input range, ensuring full compatibility.

Q: What is the operate time specification for the GM-FA-10J?

A: The GM-FA-10J has an operate time of 35 milliseconds, representing the response time from coil energization to contact closure.
