Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP0300 is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Color: Red (optical output requirement)
• Lens Transparency: Diffused (light distribution characteristic)
• Mounting Type: Through Hole (assembly compatibility)
• Wavelength - Peak: 635nm (spectral compatibility)
• Package / Case: Radial (electrical configuration)

Secondary Compatibility Criteria:

• Voltage - Forward (Vf): Within acceptable circuit design tolerance
• Current - Test: 20mA operating point
• Height (Max): 8.00mm (physical clearance)
• Lens Style: Rectangle with Flat Top (form factor)

The substitute part SSL-LX25783ID meets all primary compatibility criteria and operates within acceptable parameters for the secondary criteria, enabling direct functional substitution in applications designed for the HLMP0300.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SSL-LX25783ID is a valid functional substitute for the obsolete HLMP0300 based on alignment of critical electrical and mechanical parameters. Both components share identical wavelength-peak specification (635nm), mounting type (through-hole radial), lens transparency (diffused), and maximum height (8.00mm).

Compliance and Regulatory Status:

Both the HLMP0300 and SSL-LX25783ID carry identical regulatory classifications: REACH Unaffected, ECCN EAR99, and HTSUS 8541.41.0000. The SSL-LX25783ID carries RoHS3 compliance certification, providing additional environmental compliance assurance for new designs.

Operational Differences:

The SSL-LX25783ID operates at 2V forward voltage compared to the HLMP0300's 2.1V specification, representing a 0.1V reduction. This difference is within typical circuit design tolerance for LED indication applications and requires no circuit modification.

The SSL-LX25783ID produces 9mcd brightness at 20mA test current, compared to 2.5mcd for the HLMP0300. This represents increased luminous intensity, which may require adjustment of current-limiting resistor values if brightness consistency is critical to the application.

The SSL-LX25783ID has an 80° viewing angle compared to the HLMP0300's 100° viewing angle. This represents a 20° reduction in light distribution width and should be evaluated against specific application visibility requirements.

Physical Dimensions:

Lens size differs slightly: SSL-LX25783ID measures 7.00mm x 2.30mm compared to HLMP0300's 7.24mm x 2.42mm. Both maintain 8.00mm maximum height. These minor dimensional variations are within typical manufacturing tolerance for rectangular LED packages and do not affect through-hole mounting compatibility.

Supply Availability:

The SSL-LX25783ID is in active production status with 2100 pieces in current inventory, compared to the HLMP0300's obsolete status with 815 pieces remaining. Selection of the SSL-LX25783ID ensures long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LX25783ID be used as a direct drop-in replacement for the HLMP0300?

A: The SSL-LX25783ID is mechanically and electrically compatible for through-hole PCB mounting. However, the increased brightness (9mcd vs 2.5mcd) and narrower viewing angle (80° vs 100°) require evaluation against specific application requirements. Current-limiting resistor values may require adjustment to maintain consistent brightness output.

Q: What is the significance of the 0.1V forward voltage difference?

A: The SSL-LX25783ID operates at 2V forward voltage compared to the HLMP0300's 2.1V. This 0.1V reduction is within standard tolerance for LED indication circuits and typically does not require circuit redesign. Existing current-limiting resistor calculations remain valid.

Q: How does the increased brightness of the SSL-LX25783ID affect circuit design?

A: The SSL-LX25783ID produces 9mcd at 20mA test current, compared to 2.5mcd for the HLMP0300. If brightness consistency is required, the current-limiting resistor should be recalculated to reduce test current proportionally, or the increased brightness should be accepted as an improvement to visibility.

Q: Are there physical clearance concerns with the SSL-LX25783ID?

A: Both components maintain 8.00mm maximum height. Lens dimensions vary slightly (7.00mm x 2.30mm vs 7.24mm x 2.42mm), but these differences are within typical manufacturing tolerance for rectangular LED packages and do not affect PCB layout or mechanical clearance.

Q: What is the impact of the 20° viewing angle reduction?

A: The SSL-LX25783ID has an 80° viewing angle compared to the HLMP0300's 100°. This represents a narrower light distribution pattern. Applications requiring wide-angle visibility should evaluate whether the reduced viewing angle meets visibility requirements at intended viewing positions.

Q: Are regulatory and compliance certifications equivalent?

A: Both components carry identical REACH Unaffected, ECCN EAR99, and HTSUS 8541.41.0000 classifications. The SSL-LX25783ID additionally carries RoHS3 compliance certification, providing enhanced environmental compliance for new designs and applications subject to RoHS requirements.

Q: What is the inventory status for each component?

A: The HLMP0300 is obsolete with 815 pieces remaining in stock. The SSL-LX25783ID is in active production status with 2100 pieces in current inventory, ensuring long-term supply availability for ongoing production requirements.

Q: Are there any packaging differences between the components?

A: The HLMP0300 is supplied in standard packaging, while the SSL-LX25783ID is supplied in bulk packaging. Both use radial package configuration suitable for through-hole assembly. Packaging format does not affect component functionality or electrical performance.
