Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKLA2A2S4 is based on the following critical parameters:

Functional Category: Both the main part and substitute must operate as interlock safety switching devices.

RoHS Compliance: The GKLA2A2S4 is RoHS Compliant. The substitute part SG-B1-MA-G5 is ROHS3 Compliant, maintaining regulatory alignment.

Moisture Sensitivity Level: The GKLA2A2S4 carries MSL 1 (Unlimited). The substitute SG-B1-MA-G5 also carries MSL 1 (Unlimited), ensuring equivalent handling and storage requirements.

Product Status Consideration: While the GKLA2A2S4 is obsolete, the substitute SG-B1-MA-G5 maintains Active product status, ensuring continued availability and manufacturer support.

Certification and Approval: The substitute part carries CE, cULus, and TUV approvals, providing international regulatory recognition suitable for safety-critical applications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The SG-B1-MA-G5 serves as the designated substitute for the GKLA2A2S4. The substitute maintains equivalent moisture sensitivity classification and RoHS compliance status, satisfying regulatory requirements for both original and replacement applications.

Compliance Verification: The SG-B1-MA-G5 carries active certifications (CE, cULus, TUV) appropriate for safety interlock applications. These certifications provide assurance for deployment in regulated environments where the obsolete GKLA2A2S4 may no longer receive manufacturer support.

Inventory Continuity: With 954 units of SG-B1-MA-G5 in current stock, this substitute ensures supply chain continuity for applications previously dependent on the GKLA2A2S4.

ECCN Consideration: The GKLA2A2S4 carries an OBSOLETE ECCN designation. The substitute SG-B1-MA-G5 is classified as EAR99, which is the standard export classification for commercial electronic components and does not impose additional export restrictions.

Frequently Asked Questions (FAQ)

Q: Can the SG-B1-MA-G5 directly replace the GKLA2A2S4 in existing applications?

A: The SG-B1-MA-G5 is designated as the substitute for the GKLA2A2S4 based on functional interlock safety switching capability and equivalent moisture sensitivity classification. Both parts carry MSL 1 (Unlimited) and maintain RoHS compliance. Physical mounting, electrical interface, and circuit configuration must be verified against application-specific requirements.

Q: What is the significance of the obsolete status of the GKLA2A2S4?

A: Obsolete status indicates that the GKLA2A2S4 is no longer manufactured or supported by Honeywell Sensing and Productivity Solutions. Existing inventory (687 units) represents the final available supply. For new designs or long-term system support, transition to an active substitute such as the SG-B1-MA-G5 is necessary.

Q: Are there differences in regulatory compliance between the two parts?

A: The GKLA2A2S4 is RoHS Compliant. The SG-B1-MA-G5 is ROHS3 Compliant, representing a more recent iteration of the RoHS directive. Both classifications satisfy current regulatory requirements for hazardous substance restriction. The SG-B1-MA-G5 additionally carries CE, cULus, and TUV certifications.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the GKLA2A2S4 and SG-B1-MA-G5 carry this classification, ensuring equivalent storage and logistics requirements.

Q: What is the difference between ECCN OBSOLETE and EAR99?

A: ECCN OBSOLETE indicates that the GKLA2A2S4 no longer has an active export classification due to its discontinued status. EAR99 is the standard classification for commercial electronic components with no specific export restrictions. The SG-B1-MA-G5 classification as EAR99 permits standard commercial export procedures.
