PL-624-B-BX LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The PL-624-B-BX is a pilot light LED panel indicator manufactured by Littelfuse Inc., designed for 24V DC applications with a blue LED and quick connect termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL-624-B-BX is determined by the following critical parameters:

• Voltage Rating: 24V DC operation is mandatory
• Lamp Color: Blue LED output
• Panel Cutout Dimensions: 0.55" (13.97mm) round opening compatibility
• Lens Style: Round with domed top configuration
• Termination Style: Quick connect interface for panel mounting

The substitute part Q14P1CXXB24E from APEM Inc. satisfies all mandatory substitution criteria. This part maintains identical voltage rating, lamp color, panel cutout dimensions, and lens style. The termination style differs in connector gauge (0.110" vs 0.250"), which represents a mechanical interface variation that must be evaluated during integration.

Parameter Comparison

Engineering Selection Recommendations

The Q14P1CXXB24E qualifies as a functional substitute for the obsolete PL-624-B-BX based on matching voltage rating, lamp color, panel cutout dimensions, and lens configuration. The substitute part carries active product status with ROHS3 compliance and REACH unaffected designation, supporting long-term availability and regulatory alignment.

The primary integration consideration is the termination connector gauge difference (0.110" vs 0.250"). This mechanical interface variation requires evaluation of existing harness and connector compatibility within the target application. The substitute part's enhanced specifications—including IP67 ingress protection, 540mcd brightness rating, and 100° viewing angle—provide additional performance characteristics not documented for the original part.

Frequently Asked Questions (FAQ)

Q: Can Q14P1CXXB24E directly replace PL-624-B-BX without modification?

A: Both parts share identical panel cutout dimensions (0.55" / 13.97mm), voltage rating (24V DC), lamp color (blue), and lens style (round with domed top). The termination connector gauge differs (0.110" vs 0.250"), requiring harness or connector adapter evaluation for direct installation.

Q: What is the current consumption of the substitute part?

A: The Q14P1CXXB24E operates at 20mA. The original PL-624-B-BX current rating is not specified in available documentation.

Q: Does the substitute part meet environmental compliance requirements?

A: The Q14P1CXXB24E is ROHS3 compliant and REACH unaffected, supporting compliance with current environmental regulations. Original part compliance status is not documented.

Q: What is the brightness difference between the parts?

A: The Q14P1CXXB24E provides 540mcd brightness with a 100° viewing angle and diffused lens transparency. The original part's brightness and viewing angle specifications are not documented.

Q: Is the substitute part suitable for sealed or wet environments?

A: The Q14P1CXXB24E carries IP67 ingress protection rating. The original part's ingress protection rating is not specified.
