LTL-14AWJ Equivalent & Substitute Parts

Part Overview

The LTL-14AWJ is a bidirectional LED indicator manufactured by Lite-On Inc., featuring green and red light emission in a T-1 through-hole radial package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts become necessary when the primary part experiences supply constraints, inventory depletion, or when design requirements permit alternative configurations that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTL-14AWJ are qualified based on the following electrical and mechanical parameters:

• Color configuration: Green and Red dual-color capability
• Bidirectional or compatible configuration
• Forward voltage: 2.1V Green, 1.8V Red
• Test current: 20mA for both colors
• Mounting type: Through Hole radial package
• Lens transparency: Diffused
• Package classification: T-1 or 3mm equivalent
• RoHS3 compliance

The identified substitutes meet these core criteria while maintaining functional equivalence for LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

4301F1/5 (Visual Communications Company - VCC): This substitute matches the LTL-14AWJ in electrical specifications (2.1V Green, 1.8V Red forward voltage; 20mA test current) and mechanical configuration (T-1 bidirectional radial package). However, the product status is classified as "Not For New Designs," which restricts its use to legacy system maintenance or replacement applications only. ROHS3 compliance is maintained.

5219628F (Dialight 521 Series): This substitute provides functional equivalence through matching color configuration, test current (20mA), diffused lens transparency, and through-hole radial mounting. The device package is specified as 3mm rather than T-1, representing a mechanical variant. Product status is Active, supporting both new designs and ongoing production. ROHS3 compliance is maintained. Forward voltage specifications are not provided in the available data.

Frequently Asked Questions (FAQ)

Q: Can the 4301F1/5 be used in new designs? A: No. The 4301F1/5 is classified as "Not For New Designs" and is restricted to replacement or legacy applications only.

Q: What is the primary difference between the LTL-14AWJ and 5219628F? A: The primary difference is the package designation: LTL-14AWJ uses T-1 package, while 5219628F uses 3mm package. Both are through-hole radial configurations with equivalent electrical specifications for green and red LED indication.

Q: Are all three parts ROHS3 compliant? A: Yes. The LTL-14AWJ, 4301F1/5, and 5219628F are all ROHS3 compliant.

Q: What are the critical electrical parameters for substitution? A: Forward voltage (2.1V Green, 1.8V Red) and test current (20mA for both colors) are the primary electrical parameters determining substitution compatibility.

Q: Can the 5219628F be used as a direct replacement for the LTL-14AWJ? A: The 5219628F is electrically compatible but uses a 3mm package instead of T-1. Physical board layout and mounting hole spacing must be verified for mechanical compatibility.
