MV64531 LED Green Diffused T-1 3/4 Through Hole - Equivalent & Substitute Parts

Part Overview

The onsemi MV64531 is a green diffused LED indicator in T-1 3/4 through-hole package, rated at 2.2V forward voltage with 20mcd brightness. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with through-hole mounting, green wavelength specification, and similar electrical characteristics to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts are grouped based on the following critical parameters that determine functional equivalence:

Primary Compatibility Criteria:

Lens size: 5mm, T-1 3/4 form factor
Mounting type: Through hole, radial package
Color: Green
Lens transparency: Diffused
Forward voltage range: 2.1V to 2.2V (low-voltage group)
Wavelength: 562nm to 573nm (green spectrum)

Secondary Considerations:

Millicandela rating: 4.2mcd to 20mcd acceptable for indicator applications
Viewing angle: 40° to 75° suitable for general indication
Current rating: 10mA to 20mA test current
Product status: Active preferred; obsolete acceptable if specifications match

Excluded from Direct Substitution:

4302H5-12V and 4302H5-5V: Higher forward voltage (12V, 5V) requires circuit redesign; not pin-compatible with 2.2V designs
HLMP-3680: 5V forward voltage; different electrical requirements

Engineering Selection Recommendations

Primary Recommendation: HLMP-3507 Series (Broadcom Limited)

The HLMP-3507 family provides the most direct electrical compatibility with MV64531. Forward voltage of 2.1V matches the original design intent, and the 10mA test current allows operation within existing circuit parameters. Multiple packaging options (HLMP-3507 bulk, HLMP-3507-D0001 tape & reel, HLMP-3507-D0002 cut tape) accommodate different procurement and assembly workflows. All variants carry active product status with ROHS3 compliance and unlimited moisture sensitivity rating.

Secondary Recommendation: 151051VS04000 (Würth Elektronik)

This part maintains 2.1V forward voltage and 20mA test current matching the original MV64531 specification. Higher millicandela rating (140mcd vs. 20mcd) provides increased brightness margin for indicator applications. Narrower viewing angle (40° vs. 75°) may require circuit layout verification. Active product status and ROHS3 compliance ensure long-term availability.

Alternative for Brightness-Critical Applications: HLMP-3507-EF000 (Broadcom Limited)

This obsolete variant offers 13.9mcd brightness, closer to the original 20mcd specification than standard HLMP-3507 (4.2mcd). Electrical parameters remain identical (2.1V, 10mA). Extensive inventory (41,842 pcs) supports high-volume requirements. Suitable only when brightness performance is critical and standard HLMP-3507 is insufficient.

Not Recommended for Direct Substitution:

4302H5-12V and 4302H5-5V operate at significantly higher forward voltages (12V and 5V respectively) and require complete circuit redesign. These parts are not pin-compatible with 2.2V designs without additional current-limiting modifications.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3507 directly replace MV64531 without circuit modification?

A: Yes. Both parts operate at 2.1V to 2.2V forward voltage with compatible through-hole radial packages. The 10mA test current of HLMP-3507 versus 20mA for MV64531 represents a design margin; existing current-limiting resistors will function correctly. Verify brightness requirements, as HLMP-3507 provides 4.2mcd versus MV64531's 20mcd.

Q: What is the difference between HLMP-3507, HLMP-3507-D0001, and HLMP-3507-D0002?

A: These are identical electrical and mechanical parts with different packaging formats. HLMP-3507 is supplied in bulk; HLMP-3507-D0001 in tape & reel format; HLMP-3507-D0002 in cut tape format. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Why is 151051VS04000 brighter (140mcd) than MV64531 (20mcd)?

A: Millicandela rating depends on LED die efficiency and optical design. Higher brightness does not affect electrical compatibility. Verify that increased brightness does not cause visual glare or exceed application requirements.

Q: Can I use 4302H5-5V as a substitute?

A: No. The 4302H5-5V operates at 5V forward voltage, requiring a completely different circuit design with modified current-limiting resistors. This part is not electrically compatible with 2.2V designs.

Q: What does "Obsolete" product status mean for MV64531?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but long-term supply is not guaranteed. Active-status substitutes (HLMP-3507 series, 151051VS04000) are recommended for new designs to ensure sustained availability.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. HLMP-3507 series and 151051VS04000 all carry ROHS3 compliance certification, meeting environmental and regulatory requirements for current manufacturing standards.
