Substitute Part Grouping Explanation

The substitute part SG-B1-MA-G5 is identified as a functionally equivalent alternative based on the following substitution criteria:

Functional Classification: Both components serve interlock switching applications within safety-critical systems.

Compliance Alignment: The substitute part maintains RoHS compliance (ROHS3 Compliant) and carries the same unlimited moisture sensitivity level (MSL 1), ensuring compatibility with environmental and regulatory requirements.

Certification Status: The SG-B1-MA-G5 holds active product status with recognized approval agencies (CE, cULus, TUV), providing documented safety and performance validation.

Switching Functionality: The substitute operates as a solenoid release interlock switch with DPST-NC circuit configuration, delivering the core safety switching function required in interlock applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The GKLE44L7T4 is classified as obsolete. The SG-B1-MA-G5 maintains active product status with current manufacturing support and documented availability (954 Pcs in stock).

Compliance Framework: Both components satisfy RoHS compliance requirements. The SG-B1-MA-G5 carries ROHS3 Compliant designation with recognized third-party certifications (CE, cULus, TUV), providing documented conformance to international safety and electromagnetic compatibility standards.

Regulatory and Export Classification: The substitute part is classified under ECCN EAR99, which differs from the obsolete classification of the original component. This classification should be verified against specific end-use requirements and export control regulations applicable to the deployment region.

Moisture and Environmental Stability: Both components feature MSL 1 (Unlimited), indicating equivalent performance in moisture-sensitive applications and unrestricted storage conditions.

Functional Equivalence: The SG-B1-MA-G5 provides documented electrical specifications (2A AC/DC, 125VAC/30VDC rating, 24VDC supply) and environmental protection (IP67 rating), establishing clear functional parameters for interlock safety switching applications.

Frequently Asked Questions (FAQ)

Q: Why is the GKLE44L7T4 classified as obsolete?

A: The GKLE44L7T4 has reached end-of-life status and is no longer manufactured by Honeywell Sensing and Productivity Solutions. Obsolete classification indicates discontinued production and the absence of ongoing technical support or design updates.

Q: What makes SG-B1-MA-G5 a suitable substitute?

A: The SG-B1-MA-G5 is functionally equivalent based on shared interlock safety switching classification, identical moisture sensitivity level (MSL 1), equivalent RoHS compliance status, and active product status with documented certifications from recognized approval agencies.

Q: Are there electrical specification differences between these components?

A: The GKLE44L7T4 does not provide detailed electrical specifications in available documentation. The SG-B1-MA-G5 specifies 2A AC/DC current rating, 125VAC/30VDC voltage rating, and 24VDC supply voltage. Electrical compatibility must be verified against specific circuit requirements before implementation.

Q: What is the significance of the IP67 rating on the substitute part?

A: IP67 classification indicates dust-tight and waterproof protection, providing environmental robustness suitable for industrial interlock applications. This specification is not documented for the original component.

Q: How do the approval certifications compare?

A: The SG-B1-MA-G5 carries CE, cULus, and TUV certifications, establishing compliance with European, North American, and international safety standards. The original component's certification status is not specified in available documentation.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate RoHS compliance. ROHS3 represents the current iteration of the RoHS Directive (2011/65/EU as amended). Both components meet hazardous substance restriction requirements.

Q: Should packaging differences affect substitution decisions?

A: Both components are supplied in bulk packaging. Packaging format does not affect functional substitution; however, procurement quantities and handling procedures may require adjustment based on supplier packaging standards.

Q: What is ECCN classification and why does it differ?

A: ECCN (Export Control Classification Number) designates export control status. The substitute part's EAR99 classification should be verified against applicable export regulations for the intended deployment region and end-use application.
