PL-624-A-BX Equivalent & Substitute Parts

Part Overview

The PL-624-A-BX is an LED panel indicator manufactured by Littelfuse Inc., designed for 24V DC applications with amber illumination and quick connect termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The part features a round domed lens with 0.250" (6.3mm) quick connect terminals and a 0.55" (13.97mm) panel cutout diameter.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PL-624-A-BX is determined by the following critical parameters:

• Voltage rating: 24V DC operation
• Panel cutout diameter: 0.55" (13.97mm) round configuration
• Termination interface: Quick connect connector compatibility
• Lens style: Round domed top configuration
• Indicator color: Amber or orange spectrum illumination

The substitute part Q14P1CXXHO24E from APEM Inc. meets these core substitution criteria. While the lamp color shifts from amber to orange and the termination connector size differs (0.110" vs 0.250"), the electrical voltage requirement, panel mounting geometry, and functional indicator purpose remain aligned. The substitute maintains the same panel cutout dimensions and round domed lens style, enabling direct mechanical installation in existing panel layouts.

Engineering Selection Recommendations

The Q14P1CXXHO24E serves as the primary substitute for the obsolete PL-624-A-BX. Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status meet current regulatory requirements
• IP67 ingress protection rating provides enhanced environmental sealing compared to the original part
• Identical panel cutout dimensions (0.55" / 13.97mm) enable direct mechanical replacement without panel modification
• 24V DC voltage compatibility maintains electrical system integration
• Quick connect termination interface supports existing wiring harness configurations, though connector pin size differs (0.110" vs 0.250")

The shift from amber to orange lamp color represents a visual indicator change that must be evaluated within the context of the specific application's color-coding requirements. The substitute's 850mcd brightness rating and 20mA current specification provide quantified performance parameters absent from the original part documentation.

Frequently Asked Questions (FAQ)

Q: Can the Q14P1CXXHO24E be directly installed in the same panel cutout as the PL-624-A-BX?

A: Yes. Both parts share identical panel cutout dimensions of 0.55" (13.97mm) diameter with round domed lens styles, enabling mechanical installation without panel modification.

Q: What is the difference in termination connectors between these parts?

A: The PL-624-A-BX uses 0.250" (6.3mm) quick connect terminals, while the Q14P1CXXHO24E uses 0.110" (2.8mm) quick connect terminals. Wiring harness connectors must be verified for compatibility or adapted accordingly.

Q: Does the color change from amber to orange affect functionality?

A: The color shift represents a visual indicator change. System functionality depends on whether the application's color-coding scheme permits orange illumination as equivalent to amber. This determination must be made within the context of the specific equipment's operational requirements.

Q: What compliance advantages does the substitute provide?

A: The Q14P1CXXHO24E is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original PL-624-A-BX compliance status is not specified in available documentation.

Q: Is the substitute part actively manufactured?

A: Yes. The Q14P1CXXHO24E maintains active product status, ensuring supply availability and ongoing manufacturer support, unlike the obsolete PL-624-A-BX.

Q: What is the ingress protection rating of the substitute?

A: The Q14P1CXXHO24E carries an IP67 rating, providing protection against temporary immersion in water up to 1 meter depth. The original part's ingress protection specification is not documented.
