Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5514207 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Configuration: Single LED
• Mounting Type: Through Hole, Right Angle
• Lens Size: 3mm, T-1
• Current Rating: 20mA
• Color: Green
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Criteria:

• Voltage Rating: 4.6V nominal (tolerance range acceptable)
• Wavelength - Peak: 525nm nominal (green spectrum range acceptable)
• Viewing Angle: 30° minimum
• Millicandela Rating: 3.4mcd minimum

Substitute parts must maintain compatibility across all primary criteria. Secondary criteria allow for minor variations within acceptable engineering tolerances for LED circuit board indicator applications.

Engineering Selection Recommendations

5514207F (Dialight - Direct Substitute)

The 5514207F is the primary substitute for the obsolete 5514207. Both parts share identical electrical specifications: 4.6V voltage rating, 20mA current, 525nm wavelength, 3.4mcd brightness, and 30° viewing angle. The 5514207F maintains the same through-hole, right-angle mounting configuration and clear lens type. The 5514207F carries Active product status with ROHS3 compliance, providing long-term availability and regulatory alignment. This part is the recommended first choice for direct replacement.

SSF-LXH103GD (Lumex Opto/Components Inc. - Similar Substitute)

The SSF-LXH103GD is a cross-manufacturer alternative that maintains core compatibility: single green LED, 20mA current rating, 3mm T-1 lens size, through-hole right-angle mounting, and unlimited moisture sensitivity. However, this part introduces parameter variations: 2.1V voltage rating (lower than 5514207), 565nm wavelength (longer than 5514207), 30mcd brightness (higher than 5514207), and 60° viewing angle (wider than 5514207). The SSF-LXH103GD features a diffused, tinted lens versus the clear lens of the original part. This part is suitable only when circuit design accommodates the lower voltage requirement and when the increased brightness and wider viewing angle do not conflict with application requirements. The SSF-LXH103GD carries Active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5514207F be used as a direct replacement for the 5514207?

A: Yes. The 5514207F is a direct substitute with identical electrical and mechanical specifications. Both parts feature 4.6V rating, 20mA current, 525nm wavelength, 3.4mcd brightness, 30° viewing angle, clear lens, and through-hole right-angle mounting. The 5514207F is the recommended replacement for the obsolete 5514207.

Q: What are the key differences between the 5514207 and SSF-LXH103GD?

A: The SSF-LXH103GD differs in four parameters: voltage rating (2.1V vs. 4.6V), wavelength (565nm vs. 525nm), brightness (30mcd vs. 3.4mcd), and viewing angle (60° vs. 30°). The lens is also diffused and tinted rather than clear. These differences require circuit design verification before substitution.

Q: Is the SSF-LXH103GD compatible with designs using the 5514207?

A: Compatibility depends on circuit design. The lower 2.1V voltage rating requires verification that the application circuit can operate at this reduced voltage. The higher brightness and wider viewing angle may be acceptable or beneficial depending on application requirements. The diffused lens will produce different light distribution compared to the clear lens of the original part.

Q: What mounting configurations are available for these substitutes?

A: All three parts—5514207, 5514207F, and SSF-LXH103GD—feature through-hole, right-angle mounting with 3mm lens size (T-1 package). Mounting compatibility is maintained across all substitutes.

Q: Are these parts RoHS compliant?

A: The 5514207F and SSF-LXH103GD are both ROHS3 compliant. The original 5514207 does not specify RoHS status. Both active substitutes meet current regulatory requirements.

Q: What is the inventory status for these parts?

A: The 5514207 (obsolete) has 1031 pcs in stock. The 5514207F (active) has 975 pcs in stock. The SSF-LXH103GD (active) has 19351 pcs in stock. Availability should be confirmed at time of procurement.
