• Mounting Type: Through Hole
• Voltage - Forward (Vf): 2.1V
• Millicandela Rating: 16mcd
• Lens Style: Round with Domed Top
• Lens Size: 3.10mm Dia (±0.10mm tolerance acceptable)
• Current - Test: 10mA nominal
• Viewing Angle: 40° minimum
• Height (Max): 5.40mm to 5.60mm range

Substitute Classification:

Direct Manufacturer Equivalent: SLR-343MGT32 maintains identical electrical characteristics (2.1V, 16mcd, 10mA test current, 40° viewing angle) and mechanical form factor (3.10mm lens, 5.60mm height). Packaging differs (Cut Tape vs. Tape & Box) and product status is Active. Wavelength specification remains consistent at 563nm peak.

Parametric Equivalent: SLR-342MGT32 shares the same base series and electrical parameters (2.1V, 16mcd, 10mA test current, 40° viewing angle) with identical lens dimensions (3.10mm). Height matches at 5.40mm. Wavelength differs at 572nm dominant specification. Packaging is Cut Tape. Product status is Not For New Designs.

Similar Substitute: MT240-G-A from Marktech Optoelectronics maintains core electrical compatibility (2.1V forward voltage, 16mcd brightness, green diffused lens, 3.0mm round domed form factor). Test current is 20mA and viewing angle is 60°, representing functional enhancements. Height is 5.80mm. Wavelength is 572nm dominant with 567nm peak. Packaging is Bulk. Product status is Active.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): SLR-343MGT32 is the primary substitute. It maintains identical electrical performance (2.1V, 16mcd, 10mA, 40° viewing angle) and mechanical compatibility (3.10mm lens, 5.60mm height). The part carries Active product status, ensuring long-term availability. Packaging format changes from Tape & Box to Cut Tape. Both parts are ROHS3 compliant with MSL 1 rating.

For Parametric Compatibility: SLR-342MGT32 provides equivalent electrical and optical characteristics within the same Rohm Semiconductor SLR-342 series. Wavelength specification differs (572nm dominant vs. 563nm peak), which may affect color perception in specific applications. Product status is Not For New Designs, matching the original part. This option is suitable when packaging format (Cut Tape) is acceptable.

For Active Product Status with Enhanced Performance: MT240-G-A from Marktech Optoelectronics offers Active product status with improved specifications. Test current is 20mA and viewing angle is 60°, providing greater brightness and wider visibility. Lens size is 3.00mm (0.10mm smaller) and height is 5.80mm (0.40mm taller). Wavelength is 572nm dominant with 567nm peak. MSL rating is 2 (1 Year) versus MSL 1 (Unlimited). Bulk packaging requires handling considerations. This option is recommended for new designs requiring long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can SLR-343MGT32 be used as a direct drop-in replacement for SLR-342MGTC7?

A: Yes. SLR-343MGT32 maintains identical electrical parameters (2.1V forward voltage, 16mcd brightness, 10mA test current, 40° viewing angle) and mechanical form factor (3.10mm round domed lens, 5.60mm maximum height). The primary difference is packaging format (Cut Tape versus Tape & Box) and Active product status. Circuit-level compatibility is confirmed.

Q: What is the significance of the wavelength difference between SLR-342MGTC7 (563nm peak) and SLR-342MGT32 (572nm dominant)?

A: Both wavelengths fall within the green spectrum and are visually indistinguishable to the human eye in typical indication applications. The 563nm specification represents peak wavelength measurement, while 572nm represents dominant wavelength. Selection depends on application-specific color matching requirements. For general indication purposes, both are functionally equivalent.

Q: Is MT240-G-A suitable for applications requiring the exact 40° viewing angle of SLR-342MGTC7?

A: No. MT240-G-A specifies a 60° viewing angle, which is wider than the original 40° specification. This wider angle may affect application performance in designs requiring narrow-angle indication. MT240-G-A is suitable only when the wider viewing angle is acceptable or beneficial.

Q: What are the packaging implications when substituting SLR-342MGTC7 (Tape & Box) with SLR-343MGT32 (Cut Tape)?

A: Cut Tape packaging requires different handling and storage procedures compared to Tape & Box. Cut Tape is supplied in individual tape segments without the protective box, necessitating alternative storage and protection measures. Procurement and inventory management processes may require adjustment. Electrical and mechanical performance remains identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SLR-342MGTC7, SLR-343MGT32, SLR-342MGT32, and MT240-G-A are all ROHS3 compliant. All parts are REACH Unaffected and classified as EAR99 for export purposes.

Q: What is the difference in moisture sensitivity between the substitute parts?

A: SLR-342MGTC7, SLR-343MGT32, and SLR-342MGT32 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. MT240-G-A carries MSL 2 (1 Year) rating, requiring controlled storage conditions and limiting shelf life to one year from manufacturing date. This difference may impact long-term inventory management for MT240-G-A.
