Key Parameters

Substitute Part Grouping Explanation

The Q6F3BXXG12E qualifies as a functional substitute based on the following critical parameters:

Electrical Compatibility: Both components operate at 12V DC, ensuring direct voltage compatibility in existing circuits without modification.

Optical Function: Both provide green illumination for panel indication applications, maintaining the visual signaling function of the original design.

Mechanical Interface: The round panel cutout shape is preserved. While the cutout dimension changes from 0.33" (8.33mm) to 0.24" (6.10mm), this represents a reduction that accommodates existing panel openings designed for the larger original component.

Termination: Wire lead termination is maintained in both components, preserving connection methodology. Lead length differs slightly (8" vs. 7.87"), which is operationally insignificant for most panel-mounted applications.

Regulatory Compliance: Both components maintain ROHS3 compliance, ensuring environmental and regulatory alignment.

The primary distinction is the technology transition from incandescent to LED, which introduces improved current efficiency (20mA LED vs. unspecified incandescent current) and enhanced reliability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The Q6F3BXXG12E is suitable for applications requiring replacement of the obsolete PL-19-GC000. Selection should be based on the following engineering criteria:

Regulatory Compliance: Both components maintain ROHS3 compliance. The substitute additionally carries REACH Unaffected status and EAR99 ECCN classification, providing expanded regulatory coverage for international applications.

Product Availability: The original component is obsolete with limited remaining inventory (754 units). The substitute is active production with substantial inventory availability (7577 units), ensuring long-term supply chain continuity.

Mechanical Fit: The smaller panel cutout dimension of the substitute (0.24" vs. 0.33") requires verification that existing panel openings can accommodate the reduced size. In applications where the original larger opening cannot be modified, mechanical adaptation may be necessary.

Operational Characteristics: The LED technology of the substitute introduces defined current consumption (20mA) compared to the unspecified incandescent current, enabling precise circuit design and power budget calculations.

Frequently Asked Questions (FAQ)

Q: Can the Q6F3BXXG12E directly replace the PL-19-GC000 without circuit modification?

A: Electrical compatibility is direct at 12V DC. Mechanical compatibility requires verification that the panel cutout can accommodate the smaller 0.24" (6.10mm) dimension of the substitute. Wire lead termination and length are compatible with standard panel mounting practices.

Q: What is the primary functional difference between these components?

A: The original PL-19-GC000 uses incandescent technology, while the Q6F3BXXG12E uses LED technology. Both provide green illumination for 12V DC panel indication. The LED substitute offers improved reliability and defined current consumption characteristics.

Q: Are there any compliance differences between the original and substitute?

A: Both components are ROHS3 compliant. The substitute additionally carries REACH Unaffected designation and EAR99 ECCN classification, providing broader regulatory alignment for international markets.

Q: What is the impact of the panel cutout dimension change?

A: The substitute requires a 0.24" (6.10mm) round opening compared to the original 0.33" (8.33mm). Existing panels designed for the larger opening will accommodate the smaller component. Panels designed specifically for the smaller opening will not accept the original component.

Q: How do the wire lead lengths compare?

A: The original component provides 8" (203.20mm) leads, while the substitute provides 7.87" (200.00mm) leads. This 0.13" difference is operationally insignificant for standard panel-mounted applications and does not affect circuit routing or connection methodology.

Q: What ingress protection rating does each component provide?

A: The original component does not specify an ingress protection rating. The substitute provides IP67 protection, indicating suitability for applications requiring dust and moisture resistance.
