PCH125-DRG LED Circuit Board Indicator Equivalent & Substitute Parts
Part Overview
The PCH125-DRG is a LED Circuit Board Indicator manufactured by Visual Communications Company (VCC), featuring a dual-color configuration with green and red LEDs in a 3mm T-1 through-hole right-angle package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The part delivers 10mA operation for both color channels with diffused lens optics and 118° viewing angle.

Substitute Part Grouping Explanation
Substitution eligibility for the PCH125-DRG is determined by the following critical parameters:
Mechanical Compatibility:
- Lens size: 3mm, T-1 form factor
- Mounting configuration: Through-hole, right-angle orientation
- Lens style: Round with domed top
Electrical Compatibility:
- Dual-color configuration: Green and red LEDs in single package
- Current rating: 10mA operation for both channels
- Diffused lens type for uniform light distribution
Regulatory Compliance:
- RoHS3 compliance required
- ECCN and HTSUS classification alignment
The substitute part 5513009F from Dialight meets these core substitution criteria while maintaining active product status and full regulatory compliance.

Engineering Selection Recommendations
The 5513009F from Dialight qualifies as a direct substitute for the obsolete PCH125-DRG based on the following factors:
Mechanical Alignment: Both parts share identical 3mm T-1 through-hole right-angle mounting configurations, ensuring PCB footprint compatibility without layout modifications.
Electrical Functionality: Dual-color green and red LED configuration with 10mA current rating maintains circuit design parameters. The specified voltage ratings (2.1V green, 2V red) for the 5513009F provide defined operating parameters absent from the original part specification.
Regulatory Compliance: Both components maintain ROHS3 compliance and identical ECCN/HTSUS classifications, supporting supply chain and export documentation requirements.
Performance Considerations: The 5513009F delivers higher green luminous intensity (10mcd versus 3.7mcd) and comparable red output (4.7mcd versus 4.3mcd). The narrower viewing angle (50° versus 118°) represents a design trade-off requiring circuit-level evaluation based on application requirements.
Product Availability: The transition from obsolete to active product status ensures long-term procurement viability and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Can the 5513009F directly replace the PCH125-DRG without PCB modifications?
A: Yes. Both parts utilize identical 3mm T-1 through-hole right-angle mounting configurations. No PCB layout changes are required for mechanical installation.
Q: What are the key electrical differences between these parts?
A: The 5513009F provides explicit voltage ratings (2.1V green, 2V red) compared to the PCH125-DRG specification. Both operate at 10mA for each color channel. The 5513009F delivers higher green luminous intensity (10mcd versus 3.7mcd).
Q: Does the narrower viewing angle of the 5513009F affect circuit performance?
A: The 5513009F viewing angle is 50° compared to the PCH125-DRG at 118°. This narrower angle concentrates light output and requires evaluation based on specific application viewing geometry and indicator visibility requirements.
Q: Are both parts RoHS compliant?
A: Yes. Both the PCH125-DRG and 5513009F maintain ROHS3 compliance status.
Q: What is the packaging difference between these parts?
A: The PCH125-DRG is specified with standard packaging, while the 5513009F is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.
Q: Are there any supply chain advantages to using the 5513009F?
A: The 5513009F is an active product with 6735 units in stock, compared to the obsolete PCH125-DRG status. This ensures ongoing availability and supply chain reliability for future production runs.
Q: Do both parts share the same wavelength specifications?
A: Green wavelengths are closely matched (567nm versus 565nm). Red wavelengths are identical at 635nm for both parts.
