GLAA07C Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The GLAA07C is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, classified as SPDT (Single Pole Double Throw) with On-Momentary function. This chassis-mounted switch features a roller plunger actuator and screw terminal connections, rated for 100mA at 50V AC/DC with IP67 ingress protection.

The GLAA07C is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLAA07C is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Actuator type (Roller Plunger)
• Mounting type (Chassis Mount)
• Termination style (Screw Terminal)
• Ingress protection rating (IP67 minimum)

Electrical Compatibility Criteria:

• Current rating must equal or exceed 100mA
• Voltage ratings must support 50V AC and 50V DC operation
• RoHS compliance required

Mechanical Compatibility Criteria:

• Operating force within acceptable tolerance of 1632gf
• Operating position, pretravel, differential travel, and overtravel must accommodate existing mechanical interfaces

The GLAA07C has two identified substitutes: GLAB07C (Honeywell, same series) and D4A-3110N and D4A-3310N (Omron, different series). These parts meet the core electrical and mechanical requirements for substitution.

Parameter Comparison

Engineering Selection Recommendations

GLAB07C (Honeywell) - Primary Substitute

The GLAB07C is the preferred substitute for the obsolete GLAA07C. Both parts are from the Honeywell GLS series and share identical electrical and mechanical specifications. The GLAB07C is currently in active production status with 1086 units in stock. This substitute requires no design modifications and provides direct functional equivalence. Both parts are RoHS compliant with MSL 1 rating.

D4A-3110N and D4A-3310N (Omron) - Secondary Substitutes

The Omron D4A series parts (D4A-3110N and D4A-3310N) function as secondary substitutes. These parts share the same circuit configuration (SPDT), switch function (On-Momentary), actuator type (Roller Plunger), mounting type (Chassis Mount), termination style (Screw Terminal), and ingress protection rating (IP67). Both are currently in active production status.

Key differences exist in electrical ratings and mechanical dimensions. The D4A series supports higher current ratings (10A AC / 6A DC) and higher AC voltage (125V) compared to the GLAA07C (100mA, 50V). Operating position differs (2.205" vs 1.890"), and pretravel/differential travel values are reduced. Operating temperature range for D4A-3110N extends to 100°C; D4A-3310N operates to 80°C. Both parts are RoHS compliant with MSL 1 rating.

Substitution with D4A series parts is valid where mechanical envelope and electrical parameter differences are accommodated by the application design.

Frequently Asked Questions (FAQ)

Q: Why is the GLAA07C listed as obsolete?

A: The GLAA07C is no longer in active production. The GLAB07C serves as the active production equivalent within the Honeywell GLS series, offering identical specifications and direct functional replacement.

Q: Can GLAB07C directly replace GLAA07C without design changes?

A: Yes. The GLAB07C is electrically and mechanically identical to the GLAA07C. Both parts share the same circuit configuration, current and voltage ratings, actuator type, mounting method, termination style, operating force, and mechanical dimensions. No design modifications are required.

Q: What are the key differences between GLAA07C and the Omron D4A series substitutes?

A: The primary differences are current rating (100mA vs 10A AC / 6A DC), voltage rating (50V vs 125V AC / 30V DC), operating position (1.890" vs 2.205"), pretravel (0.100" vs 0.063"), and differential travel (0.035" vs 0.016"). Operating temperature ranges also differ. These differences require mechanical and electrical design verification before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. The GLAB07C, D4A-3110N, and D4A-3310N are all RoHS compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the difference between D4A-3110N and D4A-3310N?

A: Both parts share identical electrical and mechanical specifications. The D4A-3310N includes a status indicator feature and operates within a narrower temperature range (-10°C to 80°C) compared to D4A-3110N (-20°C to 100°C). The D4A-3110N is packaged in bulk; D4A-3310N packaging is also bulk.

Q: Can I use D4A series parts in applications designed for GLAA07C?

A: Substitution is valid only if the application design accommodates the differences in operating position, pretravel, differential travel, and electrical ratings. The higher current and voltage ratings of D4A series parts do not prevent substitution in lower-demand applications, but mechanical envelope differences must be verified against the specific application requirements.

Q: What inventory levels are available for each substitute?

A: GLAB07C has 1086 units in stock, D4A-3110N has 797 units in stock, and D4A-3310N has 889 units in stock. The original GLAA07C has 1089 units listed as new original in stock.
