Parameter Comparison

Engineering Selection Recommendations

LTL-307P (Lite-On Inc.): Active product status with ROHS3 compliance. Forward voltage of 2.1V requires circuit adjustment from the original 1.9V specification. Brightness rating of 5.6mcd is lower than the original 11.3mcd. Viewing angle reduced to 50° from 60°. Suitable for applications where lower brightness is acceptable and circuit design permits higher forward voltage operation.

SSL-LX507F3HD (Lumex Opto/Components Inc.): Active product status with ROHS3 compliance and REACH unaffected designation. Forward voltage of 2V and 10mA test current closely match original specifications. Brightness rating of 10mcd is comparable to the original 11.3mcd. Reduced height of 7.20mm may benefit space-constrained designs. Maintains 60° viewing angle.

SSL-LX507F3ID (Lumex Opto/Components Inc.): Active product status with ROHS3 compliance. Forward voltage of 2V and 60° viewing angle align with design requirements. Brightness rating of 40mcd exceeds original specification, suitable for applications requiring higher visibility. Reduced height of 7.20mm provides layout flexibility.

SSL-LX509F3ID (Lumex Opto/Components Inc.): Active product status with ROHS3 compliance. Forward voltage of 2V and 60° viewing angle maintain compatibility. Brightness rating of 40mcd provides increased visibility. Height of 8.60mm is closer to original dimension. Wavelength peak of 635nm matches original specification.

SSL-LX509F3SID (Lumex Opto/Components Inc.): Active product status with ROHS3 compliance. Forward voltage of 2V and 60° viewing angle maintain compatibility. Brightness rating of 700mcd significantly exceeds original specification, suitable for high-visibility indication applications. Height of 8.60mm is comparable to original. Wavelength peak of 636nm closely matches original specification.

Frequently Asked Questions (FAQ)

Q: Can I directly replace HLMP-3301-FG000 with any of these substitute parts?

A: Direct replacement requires verification of circuit design compatibility. The primary consideration is forward voltage variation (1.9V original to 2V or 2.1V substitutes). Circuits designed for 1.9V operation may require resistor adjustment to accommodate higher forward voltages. Brightness requirements must also be evaluated against application needs.

Q: What is the impact of forward voltage differences?

A: The original HLMP-3301-FG000 operates at 1.9V typical. Substitute parts operate at 2V or 2.1V. In series resistor circuits, this 0.1V to 0.2V increase reduces current flow through the LED. For constant-current driver circuits, this difference is negligible. Circuit redesign may be necessary for voltage-sensitive applications.

Q: How do brightness ratings affect substitution?

A: The original part provides 11.3mcd. Substitute options range from 5.6mcd to 700mcd. Lower brightness (LTL-307P at 5.6mcd) suits applications where reduced visibility is acceptable. Higher brightness options (SSL-LX507F3ID, SSL-LX509F3ID, SSL-LX509F3SID) provide increased visibility for demanding indication requirements. Application requirements determine the appropriate brightness level.

Q: Are all substitute parts mechanically compatible?

A: All substitute parts maintain the 5mm T-1 3/4 lens size and radial through-hole package. Height variations range from 7.20mm to 9.19mm. Designs with height constraints should prioritize SSL-LX507F3HD or SSL-LX507F3ID at 7.20mm maximum height. Designs with standard clearance can accommodate any substitute.

Q: What compliance certifications apply to all parts?

A: All parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. SSL-LX507F3HD and SSL-LX507F3ID are REACH unaffected. LTL-307P is REACH affected. Regulatory requirements may influence selection based on end-market compliance obligations.

Q: Can I use SSL-LX509F3SID as a direct replacement for general indication?

A: SSL-LX509F3SID operates at 700mcd brightness, significantly exceeding the original 11.3mcd specification. This part is suitable only for applications requiring high-visibility indication. Standard indication applications should use SSL-LX507F3HD or SSL-LX509F3ID for closer brightness matching.

Q: What viewing angle considerations apply?

A: The original part provides 60° viewing angle. LTL-307P reduces this to 50°, affecting visibility from wider angles. All Lumex substitutes maintain 60° viewing angle, preserving the original viewing characteristics. Applications requiring wide-angle visibility should avoid LTL-307P.
