VLWW9600 Equivalent & Substitute Parts

Part Overview

The VLWW9600 is a cool white LED indication component manufactured by Vishay Semiconductor Opto Division, designed for through-hole mounting applications. This discrete 4-DIP LED operates at 4.3V forward voltage with a 0.8mcd brightness rating and 60° viewing angle. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLWW9600 is determined by the following critical parameters:

Package Compatibility: The substitute part must use 4-DIP (0.200", 5.08mm) through-hole packaging to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Optical Characteristics: The part must be classified as white, cool color with clear lens transparency to maintain functional equivalence in indication applications.

Electrical Parameters: Forward voltage (Vf), test current, and brightness rating (millicandela) are secondary considerations that may vary within acceptable ranges for indication-class LEDs, provided the primary package and optical requirements are met.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to ensure environmental and moisture handling compatibility.

The R20WHT-5-0080 from Bivar Inc. meets all primary substitution criteria through identical package specification, matching optical classification, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The R20WHT-5-0080 is the designated substitute for the obsolete VLWW9600 based on package compatibility and regulatory alignment. Both components maintain ROHS3 compliance and MSL 1 rating, ensuring equivalent environmental handling and regulatory requirements.

The substitute part is currently in active production status with substantial inventory availability (25,423 pcs), providing supply chain continuity for replacement and new design applications. The identical 4-DIP package specification ensures direct mechanical and electrical compatibility with existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the R20WHT-5-0080 be used as a direct replacement for the VLWW9600?

A: Yes. Both components use identical 4-DIP (0.200", 5.08mm) through-hole packaging and share matching optical classification (white, cool, clear lens). The substitute part is mechanically and electrically compatible with existing PCB layouts and socket configurations designed for the VLWW9600.

Q: What are the electrical differences between these parts?

A: The R20WHT-5-0080 operates at 3.4V forward voltage compared to the VLWW9600's 4.3V, and uses a 20mA test current versus 50mA. The substitute part also provides significantly higher brightness (2000mcd versus 0.8mcd) and a wider viewing angle (80° versus 60°). Circuit designs must account for these parameter variations through appropriate current-limiting resistor selection.

Q: Are there compliance or regulatory differences?

A: No. Both parts maintain identical ROHS3 compliance status and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent regulatory and environmental handling requirements.

Q: Why is the VLWW9600 listed as obsolete?

A: The VLWW9600 is no longer manufactured by Vishay Semiconductor Opto Division. The R20WHT-5-0080 is the active substitute part available from Bivar Inc. for ongoing system support and new designs.

Q: What should be verified before implementing the R20WHT-5-0080 in an existing design?

A: Circuit designs must be reviewed for forward voltage and current requirements. The substitute part's lower forward voltage (3.4V) and test current (20mA) may require resistor value adjustments. The increased brightness (2000mcd) should be evaluated for the specific indication application to ensure it meets visibility requirements without excessive brightness.
