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

Part Overview

The PL-624-R is a pilot light LED panel indicator manufactured by Littelfuse Inc., designed for 24V DC applications with red lamp color and quick connect termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The PL-624-R features a round panel cutout of 0.55" (13.87mm) with a domed top lens style and quick connect 0.250" (6.3mm) termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL-624-R is determined by the following critical parameters that must align between the original and substitute component:

Voltage Rating: Both the original and substitute must operate at 24V DC to ensure direct compatibility with existing power supply circuits.

Panel Cutout Dimensions: The substitute must accommodate the 0.55" (13.87mm) round panel cutout to fit within the existing mechanical mounting interface without requiring panel modification.

Lamp Color: Red lamp color must be maintained to preserve visual indication consistency within the system.

Lens Style: Round domed top configuration ensures optical performance and aesthetic consistency.

Termination Style: Quick connect termination allows for direct connection compatibility, though connector pin dimensions may vary (0.250" vs. 0.110").

RoHS Compliance: Both components must meet ROHS3 compliance requirements for regulatory alignment.

The Q14P1CXXHR24E from APEM Inc. satisfies all substitution criteria while offering enhanced specifications including defined current rating (20mA), improved brightness (2800mcd), diffused lens transparency, and IP67 ingress protection.

Parameter Comparison

Engineering Selection Recommendations

The Q14P1CXXHR24E is the manufacturer-recommended substitute for the obsolete PL-624-R. Both components maintain ROHS3 compliance and operate at identical 24V DC voltage ratings. The substitute component is currently in active production status, ensuring long-term availability and supply chain continuity.

The Q14P1CXXHR24E provides enhanced specifications including defined electrical parameters (20mA current rating), improved optical performance (2800mcd brightness), and superior environmental protection (IP67 ingress rating). The panel cutout dimensions are functionally equivalent (0.55" nominal), accommodating direct mechanical installation in existing mounting interfaces.

Termination connector pin dimensions differ between the original (0.250") and substitute (0.110"), requiring connector interface verification during integration. Both components utilize quick connect termination technology, maintaining the rapid connection/disconnection capability of the original design.

Frequently Asked Questions (FAQ)

Q: Can the Q14P1CXXHR24E directly replace the PL-624-R without panel modification?

A: Yes. Both components feature 0.55" round panel cutout dimensions, enabling direct mechanical installation in existing panel interfaces without modification.

Q: What is the significance of the different termination pin sizes (0.250" vs. 0.110")?

A: The termination pin diameter differs between the two components. The original PL-624-R uses 0.250" (6.3mm) quick connect pins, while the Q14P1CXXHR24E uses 0.110" (2.8mm) pins. Connector compatibility must be verified during integration to ensure proper electrical connection.

Q: Why is the PL-624-R classified as obsolete?

A: The PL-624-R is no longer in active production. The Q14P1CXXHR24E represents the current active alternative from the manufacturer's recommended substitute list.

Q: Are both components RoHS compliant?

A: Yes. Both the PL-624-R and Q14P1CXXHR24E meet ROHS3 compliance requirements.

Q: What are the key electrical differences between these components?

A: The Q14P1CXXHR24E specifies a 20mA current rating and 2800mcd brightness output, while the PL-624-R does not provide these detailed electrical specifications. Both operate at 24V DC.

Q: Does the Q14P1CXXHR24E offer improved environmental protection?

A: Yes. The Q14P1CXXHR24E features IP67 ingress protection, providing enhanced sealing against dust and moisture compared to the unspecified ingress protection of the original PL-624-R.

Q: What packaging format is available for the Q14P1CXXHR24E?

A: The Q14P1CXXHR24E is supplied in tray packaging format.
