Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5100H7LC is determined by compatibility across the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (0.25" round) must match to ensure physical fit in existing panel installations
• Lens style (round with domed top) provides consistent appearance and light distribution characteristics

Electrical Compatibility:

• Lamp color (yellow) at wavelength 585nm maintains functional equivalence for indicator applications
• Termination style (wire leads) allows direct connection to existing wiring harnesses
• Voltage and current ratings must be evaluated within the context of the application circuit

Regulatory Compliance:

• RoHS3 compliance and REACH unaffected status ensure environmental and regulatory alignment

The Dialight 5595701027F satisfies mechanical compatibility requirements through identical panel cutout dimensions and lens configuration. Electrical parameters differ in voltage (2.1V vs. 1.9V), current (20mA vs. 7mA), and brightness (140mcd vs. 2mcd), requiring circuit evaluation for application suitability.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 5100H7LC is classified as obsolete, while the 5595701027F is active production. For new designs and long-term availability, the active status of the Dialight component provides supply chain continuity.

Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in either selection.

Mechanical Fit: Both components feature identical 0.25" round panel cutout dimensions and round domed lens style, enabling direct mechanical substitution in existing panel installations without modification.

Electrical Circuit Evaluation: The 5595701027F operates at higher voltage (2.1V vs. 1.9V) and current (20mA vs. 7mA) with significantly increased brightness (140mcd vs. 2mcd). Circuit design must accommodate these electrical differences through appropriate series resistor adjustment and power supply capability assessment.

Lead Length Consideration: The 5595701027F provides 14" wire leads compared to 6" on the original component. Installation space and wiring routing must be evaluated for the extended lead length.

Frequently Asked Questions (FAQ)

Q: Can the 5595701027F directly replace the 5100H7LC without circuit modification?

A: Mechanical fit is compatible due to identical panel cutout dimensions. Electrical circuit modification is required due to differences in forward voltage (2.1V vs. 1.9V) and maximum current (20mA vs. 7mA). Series resistor values must be recalculated for the substitute component.

Q: What is the significance of the panel cutout dimension match?

A: The 0.25" (6.35mm) round panel cutout dimension is the primary mechanical compatibility criterion. Both components share this specification, allowing installation in existing panel openings without enlargement or modification.

Q: How do the brightness ratings compare?

A: The 5595701027F provides 140mcd compared to 2mcd for the 5100H7LC. This 70-fold increase in brightness may affect visual perception in the application. Circuit design and application requirements determine whether this difference is acceptable or requires additional optical filtering.

Q: Are there differences in wavelength between these components?

A: The wavelength difference is minimal (585nm vs. 583nm), both within the yellow spectrum. This difference is not significant for typical indicator applications.

Q: What is the impact of the extended wire lead length?

A: The 5595701027F provides 14" leads versus 6" on the original. Installation planning must account for the additional 8" of lead length in panel routing and component positioning.

Q: Do both components meet the same environmental and regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8541.41.0000). Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.
