Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5595101803 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitutes:

Mandatory Matching Parameters:

• Lens color: Red
• Lens transparency: Diffused
• Peak wavelength: 650nm
• Forward voltage: 2.1V
• Maximum current: 25mA
• Millicandela rating: 34mcd
• Viewing angle: 50°
• Lens size: 5mm, T-1 3/4
• Lens style: Round with Domed Top
• Panel cutout shape: Round
• Panel cutout dimensions: 0.25" (6.35mm)
• Termination style: Wire Leads - 6" (152.40mm)
• Moisture sensitivity level: 1 (Unlimited)

All three substitute part numbers (5595101803F, 5595101003F, 5595101023F) meet these criteria and are classified as direct functional equivalents. The primary distinction between substitutes is product status and compliance certification level, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute part numbers provide complete functional equivalence to the obsolete 5595101803. Selection between active alternatives should be based on the following factors:

Product Status: Parts 5595101803F, 5595101003F, and 5595101023F all carry active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part number.

Compliance Certification: All substitute parts meet ROHS3 compliance requirements, whereas the main part number 5595101803 is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, any of the three substitutes satisfy current compliance standards.

Inventory Availability: Part 5595101003F offers the highest current inventory level at 1225 pieces, followed by 5595101803F at 1179 pieces and 5595101023F at 841 pieces. Inventory considerations may influence selection for high-volume procurement requirements.

Electrical and Mechanical Compatibility: All substitutes maintain identical electrical ratings (2.1V, 25mA), optical characteristics (650nm, 34mcd, 50° viewing angle), and mechanical form factors (5mm T-1 3/4 lens, 0.25" panel cutout, 6" wire leads). Direct pin-for-pin and form-factor replacement is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can 5595101803F, 5595101003F, and 5595101023F be used interchangeably with 5595101803?

A: Yes. All three substitute parts maintain identical electrical specifications (2.1V forward voltage, 25mA maximum current), optical performance (650nm wavelength, 34mcd brightness, 50° viewing angle), and mechanical dimensions (5mm T-1 3/4 lens, 0.25" panel cutout, 6" wire leads). Direct substitution is supported without circuit redesign or mechanical modification.

Q: What is the primary reason for substituting 5595101803?

A: The main part number 5595101803 carries an obsolete product status, limiting future availability. The three active substitute parts ensure continued supply chain access while maintaining complete functional equivalence.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The main part 5595101803 is RoHS non-compliant, while all three substitutes (5595101803F, 5595101003F, 5595101023F) are ROHS3 compliant. For applications requiring RoHS compliance, any substitute part satisfies regulatory requirements.

Q: Do the substitute parts differ in packaging or delivery format?

A: The main part number 5595101803 does not specify packaging format. All three substitute parts are supplied in bulk packaging. Packaging specifications should be confirmed with the supplier for specific procurement requirements.

Q: Which substitute part should be selected for new designs?

A: Any of the three substitute parts (5595101803F, 5595101003F, 5595101023F) are suitable for new designs. Selection may be based on inventory availability, supplier preference, or internal part numbering standards. All three maintain identical electrical and mechanical performance.

Q: Are the wire lead lengths identical across all parts?

A: Yes. All parts, including the main number and all substitutes, feature 6" (152.40mm) wire leads. Panel mounting depth and lead routing will be identical across all variants.

Q: What is the moisture sensitivity level for these LED indicators?

A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
