Substitute Part Grouping Explanation

Substitute parts for the ASMT-SGB5-ZW7Y3 are identified based on strict electrical and mechanical parameter matching within the ASMT-SGB5 base product family. Substitution eligibility requires:

Identical dominant wavelength (525nm green)
Identical forward voltage (3.2V)
Identical test current (30mA)
Identical viewing angle (120°)
Identical package type (4-PLCC surface mount)
Identical physical dimensions (3.20mm L x 2.80mm W, 2.10mm max height)
Identical lens properties (colorless, clear, round with flat top)
Identical moisture sensitivity level (2A, 4 Weeks)
Identical regulatory compliance (REACH Unaffected, EAR99)

Two substitute parts meet these criteria: ASMT-SGB5-ZX3Y3 (MFR Recommended) and ASMT-SGB5-NW703 (Parametric Equivalent).

Engineering Selection Recommendations

Both ASMT-SGB5-ZX3Y3 and ASMT-SGB5-NW703 are active product alternatives to the obsolete ASMT-SGB5-ZW7Y3. Selection between these substitutes is determined by application requirements and supply chain considerations:

ASMT-SGB5-ZX3Y3 is designated as the manufacturer-recommended substitute. This part maintains identical electrical and mechanical specifications while offering increased luminous intensity (2675mcd versus 2125mcd). Both substitute parts carry ROHS3 compliance certification, providing regulatory advantage over the original part.

ASMT-SGB5-NW703 is a parametric equivalent maintaining the original 2125mcd luminous intensity specification. This part is supplied in Tape & Reel packaging format and maintains the highest current inventory availability (6300 units).

Both substitutes are manufactured by Broadcom Limited and share identical regulatory classification (REACH Unaffected, EAR99). Selection should prioritize active product status and supply availability for new production designs.

Frequently Asked Questions (FAQ)

Q: Can ASMT-SGB5-ZX3Y3 be used as a direct replacement for ASMT-SGB5-ZW7Y3?

A: Yes. ASMT-SGB5-ZX3Y3 meets all electrical and mechanical substitution criteria. The increased luminous intensity (2675mcd versus 2125mcd) represents enhanced performance within the same package and electrical operating parameters.

Q: What is the difference between ASMT-SGB5-ZX3Y3 and ASMT-SGB5-NW703?

A: Both parts are electrically and mechanically equivalent. ASMT-SGB5-ZX3Y3 delivers 2675mcd luminous intensity, while ASMT-SGB5-NW703 maintains the original 2125mcd specification. ASMT-SGB5-NW703 is supplied in Tape & Reel packaging; ASMT-SGB5-ZX3Y3 is supplied in bulk packaging.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ASMT-SGB5-ZX3Y3 and ASMT-SGB5-NW703 carry ROHS3 compliance certification.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging formats do not affect electrical or optical performance. Packaging selection is determined by assembly process requirements and inventory management.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts share identical 4-PLCC package dimensions (3.20mm L x 2.80mm W, 2.10mm max height) and footprint requirements. No PCB redesign is required.

Q: What is the moisture sensitivity level for these parts?

A: All parts carry MSL 2A rating with 4-week floor life. Standard moisture control procedures apply during storage and assembly.
