Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

• Color configuration (Green/Yellow bidirectional requirement)
• Forward voltage specifications (2.1V Green, 2.1V Yellow)
• Test current rating (20mA)
• Mounting type (Through Hole, Radial)
• Lens transparency (Diffused)
• Package classification (T-1 or 3mm equivalent)
• RoHS compliance status

The LTL-14CDJN qualifies as a parametric equivalent with identical electrical and mechanical specifications. The Dialight 5219478F provides functional substitution with matching voltage, current, and viewing angle parameters, though with reduced brightness ratings and increased height. The Dialight 5219628F and 5219768F represent color-variant alternatives with different LED color combinations but compatible mounting and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

LTL-14CDJN (Parametric Equivalent): Direct replacement with identical specifications. Both parts maintain Active product status, ROHS3 compliance, and matching electrical/mechanical parameters. Selection between LTL-14CDJ and LTL-14CDJN depends on inventory availability and lead time requirements.

5219478F (Dialight): Functionally compatible for green/yellow bidirectional applications with matching forward voltage and test current. Brightness output is reduced by 50% for both colors. Height increases from 4.45mm to 5.70mm, requiring PCB layout verification. Moisture sensitivity level improves from 2A to 1 (Unlimited). ROHS3 compliant and Active status maintained.

5219628F (Dialight): Suitable only for applications requiring green/red color combination. Electrical parameters are not fully specified. Height is 5.70mm. Not recommended as substitute for green/yellow applications.

5219768F (Dialight): Applicable for red/yellow bidirectional applications only. Forward voltage for red is 2V (versus 2.1V standard). Brightness ratings are significantly reduced. Height is 5.70mm. Not recommended as substitute for green/yellow applications.

Frequently Asked Questions (FAQ)

Q: Can LTL-14CDJN replace LTL-14CDJ directly? A: Yes. LTL-14CDJN is a parametric equivalent with identical electrical specifications, forward voltage, test current, brightness ratings, viewing angle, and physical dimensions. Both parts are Active status and ROHS3 compliant.

Q: Is the Dialight 5219478F a direct replacement? A: The 5219478F is functionally compatible for green/yellow bidirectional LED indication. Electrical parameters match (2.1V forward voltage, 20mA test current, 80° viewing angle). However, brightness output is 50% lower for both colors, and physical height increases from 4.45mm to 5.70mm. PCB layout must accommodate the increased height.

Q: Can I use 5219628F or 5219768F as substitutes? A: No. These parts feature different color combinations (green/red and red/yellow respectively) and are not suitable for applications requiring green/yellow indication. Selection should be based on the specific color requirement of the circuit design.

Q: What are the key parameters that determine substitution compatibility? A: Critical parameters include color configuration, forward voltage (2.1V for green and yellow), test current (20mA), mounting type (through hole radial), lens transparency (diffused), and package size (3mm T-1). Brightness ratings and physical height should be verified against PCB layout constraints.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed parts including LTL-14CDJ, LTL-14CDJN, 5219478F, 5219628F, and 5219768F maintain ROHS3 compliance status.
