Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTL-16KEE is determined by strict alignment of the following parameters:

• Color: Red
• Lens Transparency: Clear
• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 5.20mm
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these core mechanical and environmental specifications. Electrical parameters (forward voltage, test current, wavelength characteristics) and optical parameters (millicandela rating, viewing angle) vary within the active product portfolio but remain within the functional envelope of red LED indication components.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as active products with current manufacturing status, providing supply continuity for the obsolete LTL-16KEE. Selection among LTL-1CHEE, SSL-LX305D4IT, and WP132XIT should be based on application-specific requirements for optical intensity and viewing angle characteristics.

LTL-1CHEE maintains manufacturer continuity as a Lite-On Inc. product and is available in high inventory volume (56,990 units). This part is RoHS3 compliant and REACH affected.

SSL-LX305D4IT, manufactured by Lumex Opto/Components Inc., offers the highest millicandela rating (50mcd) among the substitutes and is RoHS3 compliant with REACH unaffected status.

WP132XIT, manufactured by Kingbright, provides the widest viewing angle (50°) and is available in substantial inventory (10,628 units). This part is RoHS3 compliant with REACH unaffected status.

All substitute parts share identical mechanical envelope specifications, MSL rating, and forward voltage/test current characteristics, ensuring direct functional substitution within the through-hole radial LED indicator category.

Frequently Asked Questions (FAQ)

Q: Can LTL-1CHEE, SSL-LX305D4IT, and WP132XIT be used interchangeably with LTL-16KEE?

A: Yes, within the constraints of application-specific optical requirements. All three parts maintain identical mechanical form factor (3mm T-1 radial through-hole), height (5.20mm maximum), lens style (round with domed top), and environmental rating (MSL 1). Differences in millicandela rating and viewing angle must be evaluated against circuit design specifications.

Q: What are the key mechanical compatibility factors?

A: The critical mechanical parameters are lens size (3mm T-1), mounting type (through-hole radial), package configuration (radial), and maximum height (5.20mm). All substitute parts conform to these specifications, ensuring PCB footprint and mechanical assembly compatibility.

Q: How do the optical characteristics differ among the substitutes?

A: LTL-1CHEE provides 19mcd at 45° viewing angle. SSL-LX305D4IT provides 50mcd at 30° viewing angle. WP132XIT provides 20mcd at 50° viewing angle. Selection depends on required brightness and angular light distribution for the specific application.

Q: Are there compliance differences among the substitute parts?

A: All substitute parts are RoHS3 compliant and carry MSL 1 rating. LTL-1CHEE is REACH affected, while SSL-LX305D4IT and WP132XIT are REACH unaffected. Regulatory requirements for the end application should guide selection.

Q: What is the electrical compatibility?

A: All substitute parts operate at 2V forward voltage with 20mA test current, matching standard red LED indicator circuit design parameters. The LTL-16KEE electrical specifications were not provided, but the substitute parts represent the standard electrical envelope for this component category.
