Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5503012F are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Identical color configuration (Green/Red dual color)
• Matching wavelength specifications (565nm Green, 660nm Red)
• Equivalent current rating (20mA)
• Matching voltage specifications (2.1V Green, 1.8V Red)
• Identical millicandela ratings (40mcd Green, 90mcd Red)
• Same viewing angle (60°)
• Identical lens type and style (Diffused, Round with Domed Top)
• Matching lens size (5mm, T-1 3/4)
• Same mounting configuration (Through Hole, Right Angle)
• Equivalent compliance certifications (ROHS3, REACH Unaffected)

All identified substitutes maintain these parameters without deviation, ensuring direct functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5503012F, 5503005F, and 5503007010F—are functionally equivalent and mechanically interchangeable. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Supply chain logistics and procurement preferences
• Base product number designation within the 550 series (5503012, 5503005, or 5503007)
• All parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications requiring environmental compliance certification

Frequently Asked Questions (FAQ)

Q: Can 5503005F or 5503007010F be used as direct replacements for 5503012F?

A: Yes. Both parts are direct substitutes. All electrical parameters (voltage, current, wavelength, brightness) and mechanical specifications (lens size, mounting type, viewing angle) are identical, enabling direct board-level substitution without circuit modification.

Q: Are there any differences in optical performance between these parts?

A: No. All three parts specify identical wavelength (565nm Green, 660nm Red), millicandela ratings (40mcd Green, 90mcd Red), viewing angle (60°), and lens characteristics (diffused, round domed top, 5mm).

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level), ensuring equivalent regulatory and environmental compliance.

Q: What is the difference between the base product numbers (5503012, 5503005, 5503007)?

A: The base product numbers represent different product lines within the 550 series. The suffix "F" and additional designators (such as "010" in 5503007010F) indicate packaging or variant specifications. All three maintain identical electrical and mechanical performance for this application.

Q: Can these parts be mixed in the same circuit board assembly?

A: Yes. Since all parameters are equivalent, these parts can be used interchangeably within the same design without affecting circuit performance or visual indication characteristics.

Q: Which part should be selected for new designs?

A: Selection should be based on current availability, supplier preference, and procurement lead times. All parts are active products with equivalent long-term support and availability within the Dialight 550 series.
