GLLC04D Equivalent & Substitute Parts Reference

Part Overview

The GLLC04D is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) momentary contact device rated for 10A at 300V AC / 250V DC. The switch features a lever roller actuator, chassis mount configuration, and screw terminal termination with IP66 ingress protection.

The GLLC04D is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new design applications where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLLC04D is based on strict equivalence of the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT (MBB)
• Switch function: On-Momentary contact
• Current rating: 10A (AC/DC)
• Voltage rating: 300V AC / 250V DC minimum

Mechanical Equivalence Criteria:

• Actuator type: Lever with roller
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Ingress protection: IP66 minimum
• Operating temperature range: -10°C to 80°C minimum
• Mechanical life: 5,000,000 cycles minimum

Compliance Criteria:

• RoHS compliant
• MSL 1 rating

The GLLA04F meets all mandatory electrical and mechanical equivalence criteria and is classified as an active product, making it a direct substitute for the obsolete GLLC04D.

Parameter Comparison

Engineering Selection Recommendations

The GLLA04F is a direct electrical and mechanical equivalent to the GLLC04D. Both parts share identical ratings for current, voltage, circuit configuration, actuator type, mounting configuration, and termination style. Both parts maintain the same operating force, release force, operating temperature range, and mechanical life specifications.

The primary distinction is product status: GLLC04D is obsolete while GLLA04F is active. For applications currently using GLLC04D, the GLLA04F provides continuity of supply and function without design modification. Both parts carry RoHS compliance and MSL 1 ratings, ensuring compatibility with modern manufacturing and storage requirements.

The GLLA04F is suitable for direct replacement in existing designs and for new applications requiring SPDT momentary contact snap action switches with 10A / 300V AC specifications in a chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can GLLA04F be used as a direct replacement for GLLC04D?

A: Yes. The GLLA04F meets all electrical and mechanical specifications of the GLLC04D, including circuit configuration, current and voltage ratings, actuator type, mounting style, and termination method. Both parts are rated for identical operating force, release force, temperature range, and mechanical life.

Q: What is the primary reason to substitute GLLC04D?

A: The GLLC04D is classified as obsolete. The GLLA04F is an active product from the same manufacturer and series, providing continued availability for replacement and new design applications.

Q: Are there any differences in mechanical travel specifications?

A: The GLLC04D specifies operating position at 0.630" (16.0mm), pretravel at 0.138" (3.5mm), differential travel at 0.060" (1.5mm), and overtravel at 0.175" (4.5mm). The GLLA04F does not specify operating position but lists pretravel at 0.197" (5.0mm), differential travel at 0.080" (2.0mm), and overtravel at 0.197" (5.0mm). These variations fall within the functional envelope of the GLL series and do not affect substitution eligibility for standard SPDT momentary contact applications.

Q: Do both parts meet current compliance requirements?

A: Yes. Both GLLC04D and GLLA04F are RoHS compliant and carry MSL 1 (Unlimited) ratings, meeting current environmental and moisture sensitivity standards.

Q: What is the inventory status of the substitute part?

A: GLLA04F has 985 pieces in stock as new original inventory, ensuring availability for immediate procurement.
