Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5506407F is determined by the following critical parameters:

• Electrical Compatibility: Voltage rating (2V) and current rating (20mA) must match or be compatible with circuit design
• Mounting Configuration: Through-hole, right-angle orientation is required for PCB layout compatibility
• Color and Optical Properties: Red color specification with diffused lens type for consistent visual indication
• Single Configuration: Single LED element requirement for direct functional replacement
• Compliance and Availability: Active product status with current manufacturing support and regulatory compliance

The substitute part 5510409808F meets these core substitution criteria while offering enhanced specifications in certain parameters.

Parameter Comparison

Engineering Selection Recommendations

The 5510409808F serves as a direct functional substitute for the obsolete 5506407F based on matching electrical parameters (2V, 20mA) and identical mounting configuration (through-hole, right-angle). Both components maintain equivalent moisture sensitivity ratings and regulatory compliance status.

The substitute part offers the advantage of active product status with current manufacturing support and ROHS3 compliance certification. The 5510409808F delivers slightly higher brightness output (10mcd versus 8.7mcd), which provides improved visibility margin in circuit board indicator applications.

Physical differences exist in lens geometry: the 5506407F features a 4mm flat top diffused lens, while the 5510409808F uses a 3mm round domed top with tinted diffusion. The 5510409808F has a narrower viewing angle (45° versus 145°), which may affect visibility characteristics depending on application requirements and mounting orientation.

Frequently Asked Questions (FAQ)

Q: Can the 5510409808F directly replace the 5506407F without circuit modification?

A: Yes, from an electrical standpoint. Both components operate at 2V with 20mA current rating and use identical through-hole, right-angle mounting. However, the physical lens geometry differs (4mm flat top versus 3mm round domed top), which may require PCB layout verification to confirm mechanical fit within existing mounting holes and clearance envelopes.

Q: What is the impact of the narrower viewing angle on the substitute part?

A: The 5510409808F has a 45° viewing angle compared to the 5506407F's 145° viewing angle. This narrower angle concentrates light output in a more focused direction. Applications requiring wide-angle visibility may experience reduced indicator visibility from off-axis viewing positions.

Q: Does the higher millicandela rating of the substitute part affect circuit operation?

A: No. The 10mcd output of the 5510409808F versus 8.7mcd of the 5506407F represents increased brightness at identical electrical operating conditions. This provides improved visibility without requiring circuit current adjustments.

Q: Are there packaging or inventory considerations for this substitution?

A: The 5510409808F is available in bulk packaging with active product status and 868 pieces in current stock. The 5506407F is obsolete with limited remaining inventory (735 pieces). For new designs or long-term production requirements, the 5510409808F is the recommended selection.

Q: What compliance certifications apply to both parts?

A: Both components maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity ratings. The 5510409808F additionally carries ROHS3 compliance certification, providing enhanced regulatory alignment for modern manufacturing environments.
