MV57123 LED Red Diffused Rectangular Through-Hole Equivalent & Substitute Parts

Part Overview

The MV57123 is a red diffused rectangular LED from onsemi designed for indication applications in through-hole mounting configurations. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The MV57123 features a 2mm x 5mm rectangular lens with diffused transparency, 4mcd brightness rating, and 2V forward voltage typical specification. Substitute parts must maintain compatibility across mounting type, lens geometry, color, and electrical characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MV57123 are qualified based on the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Lens Size: 5.00mm x 2.00mm (±0.06mm tolerance acceptable)
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA (primary test condition)
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) Typical: 1.9V to 2.0V range
• Millicandela Rating: 4.6mcd to 4.0mcd range
• Wavelength - Peak: 623nm to 635nm range
• Height (Max): 7.50mm to 8.00mm range

All qualified substitutes maintain the rectangular 2mm x 5mm diffused red lens geometry and through-hole radial mounting configuration. Variations in forward voltage, brightness, and wavelength fall within acceptable operational tolerances for indication applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

WP113IDT (Kingbright) and 5219499F (Dialight) provide the closest electrical and mechanical alignment to the MV57123. Both parts maintain 2V forward voltage, 4mcd and 3.7mcd brightness ratings respectively, identical lens geometry (5.00mm x 2.00mm), and 20mA test current. Both are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability.

Secondary Substitutes (Acceptable Compatibility):

HLMP-S201 and HLMP-S201-D0000 (Broadcom Limited) are active products with ROHS3 compliance. These parts feature slightly larger lens dimensions (5.06mm x 2.11mm) and reduced forward voltage (1.9V typical). The HLMP-S201-D0000 variant specifies 4.6mcd brightness. Both maintain 20mA test current and through-hole radial mounting. Height specification reaches 8.00mm maximum, representing a 0.20mm increase over the MV57123.

LTL-433HR (Lite-On Inc.) operates at 2V forward voltage with 3.7mcd brightness and maintains the exact 5.00mm x 2.00mm lens geometry. This part specifies 10mA test current and 140° viewing angle. Height is 7.50mm maximum. REACH status indicates affected substance classification, requiring compliance verification for specific applications.

Compliance Considerations:

All substitute parts carry MSL 1 (Unlimited) moisture sensitivity rating, matching the MV57123 specification. ROHS3 compliance is confirmed for WP113IDT, 5219499F, HLMP-S201, HLMP-S201-D0000, and LTL-433HR. All parts maintain EAR99 ECCN classification and 8541.41.0000 HTSUS code alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can HLMP-S201 substitute for MV57123 despite the 1.9V forward voltage difference?

A: Yes. The 1.9V forward voltage of HLMP-S201 falls within acceptable operational tolerance for indication applications. Circuit designs accommodating 2V forward voltage will operate reliably with 1.9V parts. The 0.1V difference does not compromise functional performance in standard LED indication circuits.

Q: Why does LTL-433HR specify 10mA test current while MV57123 specifies 20mA?

A: Test current specification indicates the measurement condition for brightness rating, not the required operating current. LTL-433HR achieves 3.7mcd brightness at 10mA test current, while MV57123 achieves 4mcd at 20mA. Both parts operate across standard LED current ranges (5mA to 20mA) for indication applications. Circuit design determines actual operating current independent of test specification.

Q: Are the lens dimension variations between MV57123 (5.00mm x 2.00mm) and HLMP-S201 (5.06mm x 2.11mm) significant?

A: The 0.06mm and 0.11mm dimensional increases fall within standard mechanical tolerance ranges for through-hole LED applications. PCB footprints designed for 5.00mm x 2.00mm rectangular lenses accommodate the HLMP-S201 geometry without modification. Visual appearance and light distribution characteristics remain consistent across this tolerance band.

Q: Which substitute offers the best long-term availability?

A: HLMP-S201 and HLMP-S201-D0000 (Broadcom Limited) demonstrate the highest inventory levels (21,257 and 15,378 units respectively) among active products. Both carry ROHS3 compliance and active product status, indicating sustained manufacturing commitment and supply chain stability.

Q: Does the 140° viewing angle of LTL-433HR affect compatibility with MV57123 applications?

A: No. The MV57123 specifies 100° viewing angle while LTL-433HR specifies 140°. Wider viewing angle represents an enhancement for indication applications, providing visibility across a broader angular range. Applications designed for 100° viewing angle will function correctly with 140° viewing angle parts.

Q: Are all substitute parts ROHS3 compliant?

A: WP113IDT, 5219499F, HLMP-S201, HLMP-S201-D0000, and LTL-433HR all carry ROHS3 compliance certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification, matching the MV57123 regulatory profile.
