Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment for production environments.

HLMA-KH00-J0000 (Broadcom Limited) and SSL-LX3044SIC (Lumex Opto/Components Inc.) provide the closest electrical match to the MV7042, with forward voltages of 1.9V and 2.1V respectively. Both maintain the 3mm T-1 package and through-hole radial configuration. The Broadcom part offers the lowest forward voltage and compact 4.70mm height, while the Lumex part matches the MV7042 forward voltage exactly at 2.1V.

WP710A10SURCK (Kingbright) aligns precisely with the MV7042 peak wavelength at 645nm and maintains compatible electrical characteristics at 1.95V forward voltage. This part is suitable for applications requiring wavelength consistency.

WP710A10SECK/J3 (Kingbright) and XLM2ACR11W (SunLED) both operate at 2.2V forward voltage with 1600mcd and 2390mcd ratings respectively, offering increased brightness for indication applications requiring higher visibility.

151033RS03000 (Würth Elektronik) and OVLBR4C7 (TT Electronics/Optek Technology) deliver significantly higher millicandela ratings (2600mcd and 3700mcd) at 2V and 2V forward voltages, suitable for applications requiring enhanced luminous intensity.

Selection should prioritize forward voltage compatibility with existing circuit designs and millicandela rating alignment with intended indication brightness requirements.

Frequently Asked Questions (FAQ)

Q: Can the MV7042 be directly replaced with any of these substitute parts?

A: Yes. All listed substitute parts share the same core mechanical and electrical characteristics: 3mm T-1 through-hole radial package, red color with clear domed lens, 20mA test current, and forward voltages within 0.3V of the MV7042 nominal 2.1V. Direct pin-compatible substitution is supported without circuit modification.

Q: What is the significance of the millicandela rating differences?

A: Millicandela (mcd) rating indicates luminous intensity. The MV7042 operates at 150mcd, while substitutes range from 200mcd to 3700mcd. Higher mcd ratings produce brighter indication. Selection depends on the required visibility level in the target application. Brighter substitutes may require circuit current limiting adjustment if the application is brightness-sensitive.

Q: How do viewing angle variations affect substitution?

A: The MV7042 features a 60° viewing angle, the widest among all listed substitutes (30° to 45°). Narrower viewing angles concentrate light intensity in a smaller cone, increasing brightness perception in the forward direction but reducing visibility from off-axis positions. Application requirements determine acceptable viewing angle ranges.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed carry RoHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and use in regulated markets.

Q: What is the impact of forward voltage variation on circuit design?

A: Forward voltage differences of 0.1V to 0.3V are typical across LED manufacturers and production batches. The MV7042 operates at 2.1V nominal; substitutes range from 1.9V to 2.2V. Existing current-limiting resistor designs accommodate this variation. Verify circuit current limiting resistor values support the selected substitute's forward voltage to maintain proper 20mA test current operation.

Q: Which substitute offers the closest physical and electrical match?

A: HLMA-KH00-J0000 (Broadcom) and SSL-LX3044SIC (Lumex) provide the closest matches. Broadcom's part operates at 1.9V with 200mcd in a 4.70mm height package. Lumex's part matches the MV7042 forward voltage exactly at 2.1V with 1800mcd in a 4.60mm height package. Both maintain full T-1 3mm package compatibility.

Q: Is wavelength matching critical for substitution?

A: Wavelength affects perceived color consistency. The MV7042 peak wavelength is 645nm (deep red). Substitutes range from 621nm to 645nm, all within the red spectrum. For applications where color consistency is critical, WP710A10SURCK (645nm) provides exact wavelength matching. For general indication purposes, wavelength variation within the red spectrum is acceptable.

Q: What inventory considerations apply to these substitutes?

A: All substitute parts are currently in active production with substantial inventory availability. The MV7042 is obsolete with limited remaining stock (686 pcs). For new designs or production continuity, selection from active substitute parts ensures long-term supply chain stability.
