Key Parameters

Substitute Part Grouping Explanation

Substitution for the MPR3338S is determined by the following critical parameters:

• Mounting Type: Through Hole (Radial configuration)
• Application: LED Indication - Discrete
• Package Style: T-1 form factor
• Electrical compatibility: Forward voltage and current ratings
• Physical dimensions: Height and lens diameter constraints
• Regulatory compliance: REACH and RoHS status

The identified substitute SLR-343VRT32 from Rohm Semiconductor meets these substitution criteria as a through-hole LED with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SLR-343VRT32 serves as a direct substitute for the obsolete MPR3338S based on matching through-hole mounting architecture and discrete LED indication functionality. Both components share REACH compliance status, ensuring regulatory alignment for existing applications.

The SLR-343VRT32 carries ROHS3 compliance, providing enhanced environmental standards compared to the original part. Its MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Selection of the SLR-343VRT32 is appropriate for legacy system maintenance and component replacement scenarios where the original MPR3338S is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the SLR-343VRT32 directly replace the MPR3338S in existing designs?

A: Yes. Both components are through-hole mounted discrete LEDs with compatible form factors. Physical and electrical parameters align for direct substitution in legacy applications.

Q: What is the difference between "Obsolete" and "Not For New Designs" status?

A: Obsolete indicates the part is no longer manufactured or supported. Not For New Designs indicates the part remains available but is not recommended for new product development. The SLR-343VRT32 remains available for replacement purposes.

Q: Are there regulatory compliance differences between these parts?

A: Both parts maintain REACH Unaffected status. The SLR-343VRT32 additionally carries ROHS3 compliance, meeting current environmental standards.

Q: What packaging format is the SLR-343VRT32 supplied in?

A: The SLR-343VRT32 is supplied in Cut Tape (CT) packaging format, standard for through-hole discrete components.

Q: Is the SLR-343VRT32 currently in stock?

A: Yes. 4,377 pieces of new original stock are available, providing adequate supply for replacement and legacy support applications.
