Key Parameters

Substitute Part Grouping Explanation

Substitution of the GLLC03A3B is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration must be SPDT (BBM)
• Switch function must be On-Mom (momentary operation)
• Current rating must be 10A (AC/DC)
• Voltage ratings must be 300V AC and 250V DC minimum

Mechanical Equivalence Criteria:

• Actuator type must be side rotary with roller
• Mounting type must be chassis mount
• Termination style must be screw terminal
• Ingress protection must be IP66

Environmental & Compliance Criteria:

• Operating temperature range must be -10°C to 80°C
• Mechanical life must be 5,000,000 cycles
• RoHS compliance status must match

Substitute parts meeting all these parameters are functionally and mechanically interchangeable with the GLLC03A3B in the same application context.

Parameter Comparison

Engineering Selection Recommendations

The GLLC03A1B is a direct functional and mechanical equivalent to the GLLC03A3B. All electrical parameters, mechanical specifications, actuator characteristics, and environmental ratings are identical between the two parts.

The primary distinction is product status: GLLC03A3B is obsolete, while GLLC03A1B is active. For new designs, maintenance applications, or ongoing production requiring this switch type, GLLC03A1B is the appropriate selection. Both parts are RoHS compliant and carry identical compliance certifications (ECCN: EAR99; HTSUS: 8536.50.9055).

The GLLC03A1B maintains full backward compatibility with applications originally designed for GLLC03A3B, with no modifications to circuit design, mounting, or electrical specifications required.

Frequently Asked Questions (FAQ)
