MV7844 LED Red Clear T-1 T/H Equivalent & Substitute Parts

Part Overview

The MV7844 is a red LED indicator in T-1 through-hole packaging manufactured by onsemi. This discrete 2.1V radial LED is designed for indication applications with a 3mm domed lens and 375mcd brightness rating. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and design updates. Identifying compatible alternatives ensures continuity in applications requiring red LED indication with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MV7844 is determined by strict alignment of the following critical parameters:

• Color: Red
• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Lens Transparency: Clear
• Voltage - Forward (Vf) (Typ): 2.1V
• Current - Test: 20mA
• Viewing Angle: 60°
• Mounting Type: Through Hole
• Package / Case: Radial
• Height (Max): 6.30mm

The MV7044 qualifies as a parametric equivalent based on matching all critical electrical and mechanical parameters. Wavelength variations within the red spectrum (630nm vs. 645nm) remain within acceptable tolerance for indication applications where specific wavelength is not a design constraint. Additional cross-reference parts (WP710A10SURCK, OVLBR4C7, XLM2ACR11W, HLMA-KH00-J0000, WP710A10SECK/J3) are listed as recognized alternatives in the component ecosystem.

Parameter Comparison

Engineering Selection Recommendations

The MV7044 is a direct parametric equivalent to the MV7844 based on matching electrical characteristics, mechanical dimensions, and regulatory compliance. Both parts are obsolete products from onsemi with identical MSL ratings and REACH status, making them functionally interchangeable in through-hole red LED indication circuits.

When MV7044 availability is limited, the cross-reference alternatives (WP710A10SURCK, OVLBR4C7, XLM2ACR11W, HLMA-KH00-J0000, WP710A10SECK/J3) provide additional sourcing options within the red LED T-1 category. Selection among these alternatives should be based on inventory availability, lead time, and cost considerations specific to your supply chain.

Frequently Asked Questions (FAQ)

Q: Can MV7044 be used as a direct replacement for MV7844? A: Yes. The MV7044 matches all critical parameters including forward voltage, test current, viewing angle, lens dimensions, and mounting type. Both are onsemi products with identical MSL and REACH compliance.

Q: What is the difference between the 630nm and 645nm wavelengths? A: Both wavelengths fall within the red spectrum. The 630nm (MV7844) produces a slightly deeper red, while 645nm (MV7044) produces a slightly orange-red appearance. For indication applications where specific wavelength is not a design requirement, both are functionally equivalent.

Q: Are the cross-reference parts (WP710A10SURCK, OVLBR4C7, etc.) direct substitutes? A: These parts are recognized alternatives in the red LED T-1 category. Compatibility should be verified against your specific circuit requirements and mechanical constraints before implementation.

Q: What does "Obsolete" product status mean for substitution? A: Both the MV7844 and MV7044 are obsolete, meaning they are no longer in active production. Substitution is necessary for new designs or ongoing production. Inventory availability may be limited; sourcing should begin early in the design cycle.

Q: Are there any compliance concerns when substituting these parts? A: No. Both parts carry identical REACH Unaffected status and MSL 1 (Unlimited) ratings, ensuring equivalent compliance and handling requirements.
