Substitute Part Grouping Explanation

Substitution of the GKLE44L6A2 is based on functional equivalence within the interlock safety switch category. The identified substitute part SG-B1-MA-G5 shares the following critical parameters that establish substitution validity:

Key Substitution Criteria:

• Functional classification: Interlock switching mechanism
• Safety switch application category
• RoHS compliance status (both parts meet regulatory requirements)
• Moisture sensitivity level: MSL 1 (Unlimited) for both components
• Environmental sealing capability (IP67 rating on substitute)
• Electrical switching circuit type: DPST configuration

The SG-B1-MA-G5 manufactured by Panasonic Industrial Automation Sales is an active product with current production status, providing long-term availability and supply chain continuity for applications requiring interlock safety switching functionality.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The GKLE44L6A2 is classified as obsolete. The SG-B1-MA-G5 serves as the designated substitute component. Selection of the substitute is justified by:

1. Product Status Alignment: The substitute maintains active production status, ensuring continued availability and supply chain reliability.

2. Regulatory Compliance: Both components meet RoHS requirements. The substitute achieves ROHS3 compliance, representing current regulatory standards.

3. Certification Coverage: The SG-B1-MA-G5 carries CE, cULus, and TUV approvals, providing comprehensive international safety certification for interlock applications.

4. Moisture Protection: Both components share MSL 1 rating. The substitute provides IP67 ingress protection, suitable for harsh environmental conditions.

5. Functional Equivalence: Both components are classified within the interlock safety switch category with DPST switching configuration.

Implementation Consideration:

When transitioning from GKLE44L6A2 to SG-B1-MA-G5, verify that the electrical specifications of the substitute (2A AC/DC rating, 125VAC/30VDC voltage rating, 24VDC supply) align with the application circuit requirements. The substitute's solenoid release mechanism with manual override feature and panel disconnect actuator type should be evaluated against the original system design parameters.

Frequently Asked Questions (FAQ)

Q: Why is the GKLE44L6A2 listed as obsolete?

A: The GKLE44L6A2 has reached end-of-life status with the manufacturer. Honeywell Sensing and Productivity Solutions no longer produces this component. Current inventory of 1051 units represents remaining stock from prior production runs.

Q: What makes SG-B1-MA-G5 a valid substitute for GKLE44L6A2?

A: Both components function as interlock safety switches with DPST circuit configuration. Both maintain RoHS compliance and MSL 1 moisture sensitivity rating. The substitute is an active product with current manufacturing support, addressing the obsolescence issue of the original part.

Q: Are there electrical compatibility concerns when substituting?

A: The SG-B1-MA-G5 provides specified electrical parameters: 2A AC/DC current rating, 125VAC/30VDC voltage rating, and 24VDC supply voltage. Verify these specifications align with your application circuit before implementation. The original GKLE44L6A2 electrical specifications are not provided in available documentation.

Q: What is the difference between the packaging formats?

A: Both components are supplied in bulk packaging format. No special packaging considerations differentiate these parts.

Q: Does the substitute provide environmental protection?

A: The SG-B1-MA-G5 includes IP67 ingress protection rating, providing dust-tight and waterproof sealing. This exceeds the environmental specifications documented for the original GKLE44L6A2.

Q: What certifications does the substitute carry?

A: The SG-B1-MA-G5 holds CE, cULus, and TUV approvals, providing comprehensive international safety certification suitable for interlock applications across multiple regulatory jurisdictions.

Q: Is the substitute available in current inventory?

A: Yes. The SG-B1-MA-G5 maintains active production status with 954 units currently in stock, ensuring supply availability for immediate implementation.
