Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMS322T2V1-GS08 is determined by the following critical parameters:

• Package compatibility: 4-PLCC surface mount only
• Physical dimensions: 3.20mm L × 2.80mm W × 2.10mm H maximum
• Color: Red indication LEDs
• Mounting type: Surface mount
• Viewing angle: 120°
• Compliance: ROHS3 compliant

The substitute parts listed below maintain identical or compatible package geometry, mounting characteristics, and compliance certifications. Variations in forward voltage (Vf), wavelength, and luminous intensity are within acceptable ranges for red LED indication applications and do not preclude direct substitution in standard circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are manufactured by Broadcom Limited and maintain active product status, ensuring long-term availability and supply chain stability. Each substitute meets ROHS3 compliance requirements identical to the original VLMS322T2V1-GS08.

HSMJ-A401-T40M1 and HSMJ-A401-U40M1 operate at 2.2V forward voltage with 615nm dominant wavelength, representing a 15nm shift from the original 630nm specification. HSMJ-A401-U40M1 provides increased luminous intensity at 787.5mcd compared to the original 450mcd rating.

HSMZ-A400-V30M1 maintains the original 630nm dominant wavelength but operates at 2.8V forward voltage, a 0.7V increase from the VLMS322T2V1-GS08. This part requires circuit design verification to confirm voltage compatibility.

All substitute parts share identical 4-PLCC package geometry, surface mount mounting type, 120° viewing angle, and physical dimensions, enabling direct footprint compatibility on existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can HSMJ-A401-T40M1 and HSMJ-A401-U40M1 be used interchangeably with VLMS322T2V1-GS08?

A: Both Broadcom parts maintain 4-PLCC package compatibility, identical physical dimensions, and 120° viewing angle. The 615nm wavelength differs from the original 630nm, but both fall within the red LED spectrum. Forward voltage increases from 2.1V to 2.2V. Circuit designs must accommodate the 0.1V increase and verify wavelength acceptability for the application.

Q: What is the primary difference between HSMJ-A401-T40M1 and HSMJ-A401-U40M1?

A: Both parts share identical electrical and physical specifications except for luminous intensity. HSMJ-A401-T40M1 delivers 500mcd while HSMJ-A401-U40M1 delivers 787.5mcd at 50mA test current. Selection depends on required brightness for the indication application.

Q: Is HSMZ-A400-V30M1 suitable for direct replacement?

A: HSMZ-A400-V30M1 maintains 4-PLCC package compatibility and the original 630nm wavelength. However, forward voltage increases to 2.8V compared to 2.1V in the original part. Circuit design verification is required to confirm the voltage increase does not exceed current-limiting resistor or power supply constraints.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. HSMJ-A401-T40M1, HSMJ-A401-U40M1, and HSMZ-A400-V30M1 are supplied in Tape & Reel (TR) packaging, differing from the original Cut Tape (CT) format. Tape & Reel packaging is standard for high-volume production and automated assembly processes.

Q: Do all parts meet the same compliance standards?

A: All substitute parts are ROHS3 compliant and REACH unaffected, matching the original VLMS322T2V1-GS08 compliance profile. Moisture sensitivity levels vary: the original part is MSL 2 (1 Year), while all substitutes are MSL 2A (4 Weeks), requiring appropriate storage and handling protocols.
