Key Parameters

Substitute Part Grouping Explanation

Substitution for the Dialight 5503004 is determined by strict equivalence across the following critical parameters:

• Dual-color configuration: Green and red LEDs in single package
• Electrical specifications: 20mA current, 2.1V green and 1.8V red voltage ratings
• Optical characteristics: 565nm green and 660nm red wavelengths, 40mcd and 90mcd intensities respectively, 60° viewing angle
• Physical form factor: 5mm T-1 3/4 through-hole package with diffused round domed lens
• Environmental compliance: REACH Unaffected, MSL 1 rating

The substitute parts 5503004F and 5503004010F maintain identical electrical and optical performance while differing in product status and packaging configuration. Both are active products from the same manufacturer and series, ensuring functional interchangeability in circuit board applications.

Parameter Comparison

Engineering Selection Recommendations

5503004F is the primary substitute for the obsolete 5503004. Both parts are manufactured by Dialight within the 550 series and maintain identical electrical, optical, and mechanical specifications. The 5503004F carries active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment for new designs and production runs.

5503004010F provides an alternative substitute with identical performance characteristics. This variant differs in packaging configuration (bulk packaging) and maintains the same active product status and ROHS3 compliance. Selection between 5503004F and 5503004010F depends on packaging and procurement requirements rather than functional performance.

Both substitute parts are direct functional equivalents suitable for drop-in replacement in applications currently using the 5503004, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can 5503004F and 5503004010F be used interchangeably with the obsolete 5503004?

A: Yes. Both substitute parts maintain identical electrical specifications (20mA current, 2.1V green and 1.8V red voltage), optical output (40mcd green, 90mcd red at 565nm and 660nm respectively), and physical form factor (5mm through-hole with diffused domed lens). No circuit design changes are required.

Q: What is the difference between 5503004F and 5503004010F?

A: The primary difference is packaging configuration. 5503004F is supplied in bulk packaging, while 5503004010F is also supplied in bulk packaging. Both parts are functionally identical and carry active product status with ROHS3 compliance.

Q: Why is the original 5503004 marked as obsolete?

A: The 5503004 has been superseded by active product variants within the Dialight 550 series. The substitute parts 5503004F and 5503004010F provide equivalent performance with confirmed long-term availability and regulatory compliance.

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

A: The substitute parts 5503004F and 5503004010F carry ROHS3 compliance certification, while the obsolete 5503004 does not specify RoHS status. All three parts maintain REACH Unaffected status and MSL 1 rating. For applications requiring RoHS compliance, the substitute parts are the appropriate selection.

Q: Can these parts be used in new product designs?

A: Yes. The active substitute parts 5503004F and 5503004010F are suitable for new designs. Their active product status ensures ongoing manufacturing support and component availability throughout the product lifecycle.
