Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLAD01A4J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 6A AC / 550mA DC
• Voltage rating: 120V AC / 125V DC

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary, Adjustable Rod
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 33gfm
• Mechanical life: 15,000,000 cycles
• Operating position and travel characteristics: 26° operating position, 26° pretravel, 12° differential travel, 59° overtravel

Environmental & Compliance Criteria:

• Ingress protection: IP67
• Operating temperature: -25°C to 85°C
• RoHS compliance
• MSL rating: 1

The GLAA01A4J meets all these criteria and is classified as an active substitute for the obsolete GLAD01A4J.

Parameter Comparison

Engineering Selection Recommendations

The GLAA01A4J is a direct functional equivalent to the obsolete GLAD01A4J. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the GLS series and share identical electrical, mechanical, and environmental specifications.

Primary Advantage of GLAA01A4J: The GLAA01A4J maintains active product status, ensuring ongoing availability and manufacturer support. This is the critical distinction between the two parts, as the GLAD01A4J is obsolete and subject to supply discontinuation.

Compliance Considerations: Both parts are RoHS compliant and carry MSL rating 1 (unlimited moisture sensitivity level), indicating no special storage or handling requirements. Both are rated for the same operating temperature range (-25°C to 85°C) and environmental protection (IP67).

Selection Basis: For new designs or system replacements, the GLAA01A4J is the appropriate selection due to its active status. For existing systems currently using GLAD01A4J, direct substitution with GLAA01A4J is electrically and mechanically valid without circuit modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can GLAA01A4J be used as a direct replacement for GLAD01A4J in existing applications?

A: Yes. The GLAA01A4J is electrically and mechanically equivalent to GLAD01A4J. All electrical ratings (6A AC at 120V, 550mA DC at 125V), circuit configuration (SPDT), actuator type (side rotary adjustable rod), mounting type (chassis mount), and termination style (screw terminal) are identical. No circuit modifications or mechanical redesign is required.

Q: What is the primary difference between GLAD01A4J and GLAA01A4J?

A: The primary difference is product status. GLAD01A4J is obsolete, while GLAA01A4J is active. Both components are from the same GLS series by Honeywell and share identical specifications. The GLAA01A4J is the recommended selection for new applications and replacements due to ongoing availability.

Q: Are there packaging differences between these parts?

A: Yes. GLAD01A4J is supplied in standard packaging, while GLAA01A4J is supplied in bulk packaging. This difference does not affect electrical or mechanical performance and is relevant only to procurement and inventory management.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both GLAD01A4J and GLAA01A4J are RoHS compliant and carry MSL rating 1 (unlimited), indicating no special moisture sensitivity handling is required.

Q: What is the mechanical life expectancy of these switches?

A: Both parts are rated for 15,000,000 mechanical cycles, indicating equivalent durability and operational lifespan under specified conditions.

Q: Are the operating force and travel characteristics identical?

A: Yes. Both parts have identical operating force (33gfm), operating position (26°), pretravel (26°), differential travel (12°), and overtravel (59°). These parameters determine the switch actuation behavior and are fully equivalent.

Q: What is the ingress protection rating for these switches?

A: Both parts carry IP67 rating, indicating dust-tight and waterproof protection suitable for harsh environmental applications.
