TLWR9600 Equivalent & Substitute Parts

Part Overview

The TLWR9600 is a red LED indication component manufactured by Vishay Semiconductor Opto Division, part of the TELUX™ series. This through-hole mounted discrete LED operates at 2.2V forward voltage with a dominant wavelength of 615nm and provides a 60° viewing angle in a 4-DIP package format. The TLWR9600 is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. Substitute parts must maintain identical electrical characteristics, mechanical compatibility, and package specifications to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLWR9600 are qualified based on strict parameter matching across the following criteria:

Electrical Parameters: Forward voltage (2.2V), test current (70mA), and wavelength specifications (dominant 615nm or 618nm, peak 624nm) must remain constant to ensure circuit compatibility and visual consistency.

Mechanical Parameters: Package type (4-DIP 0.200" / 5.08mm), physical dimensions (7.62mm L x 7.62mm W, 6.40mm max height), and through-hole mounting configuration must be identical for PCB compatibility without layout modification.

Optical Parameters: Color (red), lens transparency (clear), lens style (round with domed top), and viewing angle (60°) must match to preserve intended indication functionality.

Compliance Parameters: RoHS3 compliance, MSL rating (1 - Unlimited), REACH unaffected status, and ECCN/HTSUS classifications must align with the original specification.

The TLWR7600 and TLWR8600 meet all substitution criteria. Both are active products in the TELUX™ series with identical electrical, mechanical, and compliance characteristics. The TLWR7600 features a dominant wavelength of 618nm (versus 615nm in the TLWR9600), representing a minor spectral variation within acceptable red LED indication parameters. The TLWR8600 matches the TLWR9600 wavelength specification exactly at 615nm dominant wavelength.

Parameter Comparison

Engineering Selection Recommendations

Both TLWR7600 and TLWR8600 are qualified substitutes for the obsolete TLWR9600. Selection between these alternatives is based on product availability and wavelength specification requirements:

TLWR8600 provides exact wavelength matching at 615nm dominant wavelength, making it the primary choice when spectral consistency with the original TLWR9600 design is required.

TLWR7600 operates at 618nm dominant wavelength, a 3nm variation within the red LED spectrum. This substitute is suitable when wavelength tolerance permits minor spectral deviation and when inventory availability favors this part number.

Both substitutes maintain full compliance with RoHS3, REACH, and MSL requirements. Active product status ensures long-term availability and supply chain continuity compared to the obsolete TLWR9600.

Frequently Asked Questions (FAQ)

Q: Can TLWR7600 and TLWR8600 be used interchangeably with TLWR9600?

A: Both parts are direct substitutes meeting all electrical, mechanical, and compliance parameters. The TLWR8600 matches the original wavelength specification exactly. The TLWR7600 introduces a 3nm wavelength variation (618nm vs. 615nm) but remains within red LED indication parameters.

Q: What is the significance of the wavelength difference between TLWR9600 (615nm) and TLWR7600 (618nm)?

A: Both wavelengths fall within the red LED spectrum with identical peak wavelength (624nm). The 3nm dominant wavelength difference produces a visually imperceptible color shift for indication applications. Selection depends on whether the original design specifies wavelength tolerance.

Q: Are the package dimensions identical across all three parts?

A: Yes. TLWR9600, TLWR7600, and TLWR8600 all use 4-DIP (0.200", 5.08mm) packaging with identical physical dimensions (7.62mm L x 7.62mm W, 6.40mm max height) and through-hole mounting configuration. No PCB layout modification is required for substitution.

Q: What is the product status difference, and why does it matter?

A: TLWR9600 is classified as obsolete, indicating discontinued production and limited future availability. TLWR7600 and TLWR8600 are active products, ensuring ongoing supply and long-term design support. Substitution to active parts is recommended for new designs and production continuity.

Q: Do all three parts meet current compliance requirements?

A: Yes. TLWR9600, TLWR7600, and TLWR8600 are all ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Compliance certifications are identical across all three parts.

Q: Which substitute should be selected for new designs?

A: TLWR8600 is recommended for new designs due to exact wavelength matching (615nm) and active product status. TLWR7600 is an alternative when inventory or supply considerations favor this part number, with the understanding that a minor 3nm wavelength variation exists.
