PL-624-G LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PL-624-G is a pilot light LED panel indicator manufactured by Littelfuse Inc., designed for 24V DC applications with a green LED and quick connect termination. This component is classified as obsolete, making it necessary to identify active equivalent parts for ongoing system maintenance and new designs. The PL-624-G features a round domed lens style with a 0.55" (13.87mm) panel cutout, suitable for standard indicator light applications requiring green illumination at 24V DC.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL-624-G is determined by strict alignment of the following critical parameters:

• Voltage Rating: 24V DC operation is mandatory for direct replacement
• Lamp Color: Green LED output must be maintained
• Panel Cutout Dimensions: 0.55" (13.87mm) round cutout ensures mechanical fit
• Lens Style: Round domed top configuration for consistent appearance and light distribution
• Termination Style: Quick connect interface for electrical connection compatibility
• Type: LED technology requirement
• Ratings: DC operation specification

The Q14P1CXXG24E from APEM Inc. meets all these critical substitution criteria. Additional parameters such as current rating, lens transparency, viewing angle, and ingress protection represent enhanced or differing specifications that do not prevent substitution but may affect performance characteristics in specific applications.

Parameter Comparison

Engineering Selection Recommendations

The Q14P1CXXG24E is the manufacturer-recommended substitute for the obsolete PL-624-G. Both components maintain ROHS3 compliance and are rated for 24V DC operation with green LED illumination. The substitute part is currently in active production status with 2420 units in stock, ensuring availability for replacement and new applications.

The Q14P1CXXG24E provides additional specifications including a defined current rating of 20mA, diffused lens transparency, 100° viewing angle, and IP67 ingress protection. These enhanced characteristics do not compromise compatibility with the original PL-624-G application requirements and may provide improved performance in environmental conditions requiring sealed operation.

Panel cutout dimensions are nominally equivalent (0.55" / 13.87mm vs. 13.97mm), supporting direct mechanical installation. The termination style differs in connector gauge (0.250" vs. 0.110"), requiring verification of mating connector compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Q14P1CXXG24E directly replace the PL-624-G without modification?

A: The Q14P1CXXG24E meets the critical substitution parameters: 24V DC voltage, green LED color, round domed lens, and compatible panel cutout dimensions. However, the quick connect termination gauge differs (0.110" vs. 0.250"), requiring verification that mating connectors in your application are compatible with the substitute part's connector specification.

Q: What is the current consumption of the Q14P1CXXG24E?

A: The substitute part is rated at 20mA. The original PL-624-G current specification was not provided in the available documentation.

Q: Does the Q14P1CXXG24E offer improved environmental protection?

A: Yes. The Q14P1CXXG24E includes IP67 ingress protection, whereas the original PL-624-G ingress protection rating was not specified. This enhancement provides sealed operation suitable for applications exposed to moisture or dust.

Q: Are both parts RoHS compliant?

A: Both the PL-624-G and Q14P1CXXG24E are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What is the viewing angle of the substitute part?

A: The Q14P1CXXG24E provides a 100° viewing angle with diffused lens transparency, enabling visibility across a wider angular range compared to the original part specification.
