Substitute Part Grouping Explanation

Substitution of the GKLE44L9A2 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 substitutability:

Key Substitution Criteria:

• Functional classification: Interlock solenoid release mechanism
• Switch type: Safety-rated interlock control
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• RoHS compliance: Both meet RoHS standards (GKLE44L9A2 RoHS Compliant; SG-B1-MA-G5 ROHS3 Compliant)
• Environmental sealing: SG-B1-MA-G5 provides IP67 rating (dust tight, waterproof)
• Regulatory approvals: SG-B1-MA-G5 carries CE, cULus, and TUV certifications

The SG-B1-MA-G5 represents an active production alternative with enhanced specifications and current availability of 954 units in stock.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

Compliance Considerations:

Both components meet RoHS requirements. The SG-B1-MA-G5 carries ROHS3 Compliant status, representing the current regulatory standard. The substitute part holds CE, cULus, and TUV certifications, establishing compliance with international safety and performance standards applicable to interlock safety switches.

Availability and Supply Chain:

The SG-B1-MA-G5 is in active production status with 954 units currently in stock, providing superior long-term supply assurance compared to the obsolete GKLE44L9A2.

Environmental and Operational Specifications:

The SG-B1-MA-G5 specifies IP67 ingress protection, operating temperature range of -25°C to 70°C, and defined electrical ratings (2A AC/DC, 125VAC/30VDC). These specifications establish clear operational boundaries for component selection in specific application environments.

Frequently Asked Questions (FAQ)

Q: Why is the GKLE44L9A2 classified as obsolete?

A: The GKLE44L9A2 is no longer manufactured by Honeywell Sensing and Productivity Solutions. Obsolete classification indicates end-of-life status and unavailability of future production units beyond current inventory.

Q: What makes SG-B1-MA-G5 a suitable substitute for GKLE44L9A2?

A: Both components function as interlock safety switches with identical Moisture Sensitivity Level (MSL 1) and RoHS compliance. The SG-B1-MA-G5 is an active production component with enhanced specifications including IP67 environmental protection and current regulatory certifications (CE, cULus, TUV).

Q: Are there electrical parameter differences between these components?

A: The GKLE44L9A2 does not specify electrical parameters in available documentation. The SG-B1-MA-G5 specifies DPST-NC circuit configuration, 2A AC/DC current rating, 125VAC/30VDC voltage rating, and 24VDC supply voltage. Application-specific electrical requirements must be evaluated against these specifications.

Q: What is the packaging difference?

A: The GKLE44L9A2 packaging is not specified. The SG-B1-MA-G5 is supplied in Bulk packaging with Cable Leads termination style and includes manual override and panel disconnect actuator features.

Q: Does the SG-B1-MA-G5 provide better environmental protection?

A: Yes. The SG-B1-MA-G5 carries IP67 rating (dust tight, waterproof) with operating temperature range -25°C to 70°C. The GKLE44L9A2 environmental specifications are not documented.

Q: Are both components RoHS compliant?

A: Yes. The GKLE44L9A2 is RoHS Compliant. The SG-B1-MA-G5 is ROHS3 Compliant, representing the current RoHS standard.

Q: What regulatory approvals does the substitute part hold?

A: The SG-B1-MA-G5 holds CE, cULus, and TUV certifications, establishing compliance with European, North American, and international safety standards for interlock safety switches.
