Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LTL-1CHG (Lite-On Inc.)

LTL-1CHG is the manufacturer-recommended substitute from Lite-On Inc., maintaining product line continuity. This part is active, RoHS3 compliant, and carries REACH Affected status. It provides 12.6mcd brightness at 2.1V forward voltage with 20mA test current.

Alternative Substitutes: SSL-LX305D4GD and WP132XGD

Both SSL-LX305D4GD (Lumex Opto/Components Inc.) and WP132XGD (Kingbright) are active, RoHS3 compliant alternatives with identical mechanical form factors. SSL-LX305D4GD operates at 2.2V with 15mcd brightness. WP132XGD operates at 2.2V with 25mcd brightness and carries REACH Unaffected status.

All three substitute parts maintain mechanical compatibility with the LTL-16KG through identical lens dimensions, mounting type, package configuration, and maximum height specifications. Selection among substitutes should be based on circuit voltage requirements, brightness specifications, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can LTL-1CHG directly replace LTL-16KG in existing designs?

A: Yes. LTL-1CHG maintains identical mechanical dimensions (3mm T-1 lens, 5.20mm height, radial through-hole package) and electrical characteristics (green diffused lens, standard configuration). The primary difference is active product status and specified electrical parameters (2.1V forward voltage, 20mA test current, 12.6mcd brightness).

Q: What are the key differences between the three substitute parts?

A: All three substitutes share identical mechanical form factors. Electrical differences include: LTL-1CHG operates at 2.1V with 12.6mcd; SSL-LX305D4GD operates at 2.2V with 15mcd; WP132XGD operates at 2.2V with 25mcd. Compliance differences include REACH status variation between manufacturers.

Q: Are there lens size variations among substitutes?

A: LTL-1CHG specifies 3.10mm diameter, while SSL-LX305D4GD and WP132XGD specify 3mm T-1 form factor. These variations remain within standard T-1 LED specifications and maintain mechanical compatibility with LTL-16KG PCB footprints.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. LTL-1CHG, SSL-LX305D4GD, and WP132XGD are all RoHS3 compliant. REACH status differs: LTL-1CHG is REACH Affected; SSL-LX305D4GD and WP132XGD are REACH Unaffected.

Q: What is the MSL rating for all parts?

A: All parts, including the original LTL-16KG and all three substitutes, carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
