Substitute Part Grouping Explanation

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

Functional Classification: Both components serve interlock switching applications. The GKLE44L7A2 is categorized as an interlock safety switch, while the SG-B1-MA-G5 functions as an interlock solenoid release switch.

Compliance Alignment: Both parts maintain RoHS compliance (GKLE44L7A2: RoHS Compliant; SG-B1-MA-G5: ROHS3 Compliant) and share identical Moisture Sensitivity Level (MSL 1 - Unlimited).

Availability Status: The substitute part SG-B1-MA-G5 maintains Active product status with 954 units in current inventory, providing ongoing supply availability compared to the obsolete GKLE44L7A2.

Electrical Specifications: The SG-B1-MA-G5 provides defined electrical parameters including DPST-NC circuit configuration, 2A current rating (AC/DC), and dual voltage support (125VAC, 30VDC).

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Mitigation: The GKLE44L7A2 is classified as obsolete. For new designs or long-term system support, the SG-B1-MA-G5 provides an active product alternative with confirmed ongoing manufacturing and supply availability.

Compliance Continuity: Both components maintain equivalent RoHS compliance status and identical MSL ratings, ensuring regulatory and environmental compliance requirements are preserved during substitution.

Certification Coverage: The SG-B1-MA-G5 carries multiple international approvals (CE, cULus, TUV), providing broader certification coverage than the GKLE44L7A2 specifications provided.

Supply Chain Reliability: With 954 units in current inventory and active product status, the SG-B1-MA-G5 offers superior supply chain continuity compared to the obsolete GKLE44L7A2.

Frequently Asked Questions (FAQ)

Q: Can the SG-B1-MA-G5 directly replace the GKLE44L7A2 in existing applications?

A: Substitution feasibility depends on the specific electrical and mechanical requirements of the original application. The SG-B1-MA-G5 provides defined specifications (DPST-NC circuit, 2A rating, 125VAC/30VDC voltage support) that must be verified against the original GKLE44L7A2 application requirements. Mechanical mounting and termination compatibility must be confirmed through design documentation review.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 (Unlimited) indicates both components have unlimited shelf life and require no special moisture control during storage or handling. This classification ensures equivalent environmental stability between the original and substitute components.

Q: Why is the GKLE44L7A2 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The part remains available through existing inventory (633 units), but no future manufacturing is planned. For applications requiring long-term component availability, transition to active alternatives such as the SG-B1-MA-G5 is recommended.

Q: What certifications does the SG-B1-MA-G5 carry?

A: The SG-B1-MA-G5 holds CE, cULus, and TUV certifications, providing compliance for European, North American, and international regulatory requirements.

Q: How do the packaging specifications differ between these parts?

A: The GKLE44L7A2 packaging is not specified in available documentation. The SG-B1-MA-G5 is supplied in Bulk packaging. Specific packaging requirements for your application should be confirmed with the supplier.
