Engineering Selection Recommendations

The LTW-010DCG is the primary substitute for the obsolete LTW-010DCG-S1. Selection is based on the following factors:

Product Status: The LTW-010DCG-S1 is classified as obsolete, while the LTW-010DCG maintains active product status with 45,100 units in stock, ensuring supply chain continuity and long-term availability.

Compliance & Certifications: The LTW-010DCG carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components in regulated markets.

Electrical Compatibility: The forward voltage increase from 3.1V to 3.3V (+0.2V) and brightness increase from 2200mcd to 2250mcd (+50mcd) remain within standard engineering tolerances for LED indication applications. Circuit designs accommodating the original 3.1V specification will function with the 3.3V substitute without performance degradation.

Mechanical & Packaging Compatibility: Identical package configuration, physical dimensions, and mounting characteristics ensure direct PCB-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LTW-010DCG directly replace the LTW-010DCG-S1 without circuit modification?

A: Yes. The LTW-010DCG is mechanically and electrically compatible. The 0.2V forward voltage increase and 50mcd brightness increase fall within standard LED tolerance ranges and do not require circuit redesign for indication applications.

Q: What is the significance of the product status change from obsolete to active?

A: The LTW-010DCG-S1 is no longer manufactured. The LTW-010DCG is the active equivalent with confirmed supply availability (45,100 units in stock), ensuring component procurement for production and field replacement applications.

Q: Are there compliance differences between the two parts?

A: The LTW-010DCG includes RoHS3 compliance and REACH unaffected certification, meeting current regulatory standards. The LTW-010DCG-S1 compliance status is not specified in available documentation.

Q: Do the physical dimensions match exactly?

A: Yes. Both parts share identical dimensions: 3.70mm length, 0.90mm width, and 0.43mm maximum height. PCB footprints and mounting requirements are identical.

Q: What is the packaging difference between the two parts?

A: The LTW-010DCG-S1 packaging is not specified. The LTW-010DCG is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual and automated assembly processes.

Q: Are the viewing angles identical?

A: Yes. Both parts maintain a 115° viewing angle, ensuring equivalent light distribution characteristics in indication applications.
