Substitute Part Grouping Explanation

Substitution of the GKRG46MXA2-F21 is based on the following critical parameters:

Functional Classification: Interlock safety switching mechanism Circuit Configuration: Safety-rated switching topology Compliance Requirements: RoHS compliance and regulatory certifications Environmental Rating: Moisture sensitivity level compatibility (MSL 1) Mechanical Interface: Physical form factor and actuator compatibility

The identified substitute part SG-B1-MA-G5 from Panasonic Industrial Automation Sales fulfills the interlock switching function with documented electrical and mechanical specifications. This substitute maintains RoHS3 compliance and operates within equivalent environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The GKRG46MXA2-F21 is classified as obsolete. The SG-B1-MA-G5 represents an active production alternative with documented electrical specifications and current regulatory certifications (CE, cULus, TUV). Both components maintain MSL 1 rating and RoHS compliance status.

Compliance Considerations: The substitute part carries ROHS3 compliance, which supersedes the RoHS compliance of the original part. The SG-B1-MA-G5 includes third-party certifications (CE, cULus, TUV) that provide additional assurance for safety-critical applications.

Environmental Suitability: The SG-B1-MA-G5 specifies IP67 ingress protection and an operating temperature range of -25°C to 70°C. These parameters should be verified against the original application requirements.

Electrical Parameters: The substitute part is rated for 2A (AC/DC) at 125VAC or 30VDC, with 24VDC supply voltage. Verify these ratings align with the original circuit design requirements.

Frequently Asked Questions (FAQ)
