Substitute Part Grouping Explanation

Substitution for the Dialight 5595201807 is based on strict electrical and mechanical parameter matching within the 559 series green LED indicator family. The following criteria determine substitutability:

Primary Matching Criteria:

• Lamp color: Green
• Lens transparency: Diffused
• Lens size: 5mm, T-1 3/4
• Panel cutout shape and dimensions: Round, 0.25" (6.35mm)
• Wavelength - peak: 563nm
• Viewing angle: 50°
• Termination style: Wire leads - 14" (355.60mm)
• Forward voltage: 2.2V

Secondary Consideration:

• Maximum current rating: 25mA (main part) vs. 20mA (5595201027F) - represents a reduced current specification that maintains compatibility in applications operating below the original 25mA rating

The substitute parts 5595201807F, 5595201017F, and 5595201027F maintain all primary matching criteria. The 5595201027F variant operates at 20mA maximum current, which is a subset of the original 25mA specification and remains compatible for circuits designed to operate within this lower current envelope.

Parameter Comparison

Engineering Selection Recommendations

5595201807F - Direct manufacturer equivalent with active product status. Maintains identical electrical and mechanical specifications to the obsolete 5595201807. Offers ROHS3 compliance, addressing regulatory requirements for new designs and production runs.

5595201017F - Parametric equivalent with active product status. Identical specifications to 5595201807F. Provides ROHS3 compliance and represents an alternative active source within the 559 series.

5595201027F - Parametric equivalent with reduced maximum current rating (20mA vs. 25mA). Active product status with ROHS3 compliance. Suitable for applications where circuit design operates at or below 20mA. Highest inventory availability (1785 pcs) among substitute options.

All substitute parts are ROHS3 compliant, addressing environmental and regulatory compliance requirements that the obsolete 5595201807 does not meet. Selection between active equivalents should be based on application current requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 5595201027F replace 5595201807 in all applications? A: 5595201027F is compatible with applications designed to operate at 20mA maximum current or below. Applications requiring the full 25mA rating must use 5595201807F or 5595201017F.

Q: What is the difference between 5595201807F and 5595201017F? A: Both parts are parametric equivalents with identical electrical and mechanical specifications. Both maintain 25mA maximum current rating and ROHS3 compliance. Selection may be based on inventory availability or supplier preference.

Q: Why is the original 5595201807 obsolete? A: The part is classified as obsolete. Active equivalents 5595201807F, 5595201017F, and 5595201027F provide continued availability with improved regulatory compliance (ROHS3).

Q: Are all substitute parts mechanically compatible with existing panel cutouts? A: Yes. All substitute parts maintain the identical 0.25" (6.35mm) round panel cutout dimension and 5mm T-1 3/4 lens form factor, ensuring direct mechanical compatibility.

Q: What is the impact of the 20mA vs. 25mA current difference? A: The 20mA maximum rating on 5595201027F represents a reduced current specification. This part is suitable for circuits operating within the 20mA envelope. Circuits requiring 25mA operation must use 5595201807F or 5595201017F.

Q: Are all substitute parts RoHS compliant? A: Yes. All three substitute parts (5595201807F, 5595201017F, 5595201027F) are ROHS3 compliant, whereas the original 5595201807 is RoHS non-compliant.
