Key Parameters

Substitute Part Grouping Explanation

Substitution of the GKLA2K3S4 is based on the following criteria derived from the provided parameters:

Primary Substitution Basis:

• Functional classification as an interlock safety switching device
• RoHS compliance requirement (RoHS Compliant status)
• Moisture sensitivity level compatibility (MSL 1)
• Active product status of the substitute component

Identified Substitute: The SG-B1-MA-G5 manufactured by Panasonic Industrial Automation Sales qualifies as a substitute based on:

• Interlock solenoid release functionality with DPST-NC circuit configuration
• RoHS3 Compliant certification (meets or exceeds RoHS requirements)
• MSL 1 rating (Unlimited moisture sensitivity level)
• Active product status ensuring ongoing availability and support

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement:

The SG-B1-MA-G5 is the designated substitute for the GKLA2K3S4 based on functional equivalence and compliance alignment. The substitute component maintains RoHS compliance through RoHS3 certification and preserves the MSL 1 rating of the original part.

Compliance Considerations:

Both components meet RoHS requirements. The SG-B1-MA-G5 carries additional third-party certifications (CE, cULus, TUV) and achieves IP67 ingress protection, providing enhanced environmental robustness compared to the original specification.

Availability:

The GKLA2K3S4 is obsolete with limited remaining inventory (946 pcs). The SG-B1-MA-G5 is an active product with current inventory availability (954 pcs), ensuring long-term supply chain continuity.

Technical Specifications:

The SG-B1-MA-G5 provides defined electrical parameters (2A AC/DC, 125VAC/30VDC) and operating conditions (-25°C ~ 70°C) that were not specified for the original GKLA2K3S4. These specifications should be verified against application requirements prior to implementation.

Frequently Asked Questions (FAQ)

Q: Why is the GKLA2K3S4 being discontinued?

A: The GKLA2K3S4 has reached obsolete status in the manufacturer's product lifecycle. Honeywell Sensing and Productivity Solutions has transitioned this interlock safety switch to end-of-life status.

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

A: The SG-B1-MA-G5 functions as an interlock solenoid release switch with equivalent safety switching capability. Both components share RoHS compliance and MSL 1 moisture sensitivity ratings, meeting the core substitution criteria for interlock safety applications.

Q: Are there packaging differences between the GKLA2K3S4 and SG-B1-MA-G5?

A: The GKLA2K3S4 packaging is not specified in the available data. The SG-B1-MA-G5 is supplied in Bulk packaging with Cable Leads termination style and Panel Disconnect actuator type.

Q: What certifications does the substitute component carry?

A: The SG-B1-MA-G5 holds CE, cULus, and TUV approvals, providing international compliance documentation for industrial automation applications.

Q: Is the SG-B1-MA-G5 rated for the same voltage and current as the original part?

A: The GKLA2K3S4 voltage and current ratings are not provided in the available documentation. The SG-B1-MA-G5 is rated for 2A (AC/DC) at 125VAC or 30VDC with 24VDC supply voltage. Application requirements must be verified against these specifications.

Q: What is the operating temperature range of the substitute?

A: The SG-B1-MA-G5 operates across -25°C to 70°C. The original GKLA2K3S4 operating temperature range is not specified.

Q: Does the substitute offer improved environmental protection?

A: Yes. The SG-B1-MA-G5 provides IP67 ingress protection (dust tight, waterproof), which exceeds the environmental specifications available for the GKLA2K3S4.
