Key Parameters

Substitute Part Grouping Explanation

Substitution of the C10974_GT4-WW is determined by the following critical parameters:

Mechanical Compatibility:

• Lens size (35mm Dia)
• Lens style (Round with Flat Top)
• Mounting type (Adhesive)
• Number of LEDs (4)

Optical Characteristics:

• Viewing angle range
• Lens transparency (Diffused)
• Optical pattern (Wide)

Material & Environmental:

• Material composition (Acrylic)
• RoHS compliance status
• MSL rating

The substitute part C10973_GT4-W shares the same series designation (GT4), mechanical form factor, material composition, and mounting methodology. Both parts are designed for 4-LED configurations with 35mm diameter acrylic lenses and adhesive mounting. The primary difference lies in the viewing angle specification: C10973_GT4-W provides 36°/38° viewing angle versus the 60°/62° of the main part.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The C10974_GT4-WW is classified as obsolete. The C10973_GT4-W is an active product within the same GT4 series and maintains full mechanical and material compatibility. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

Optical Angle Consideration:

The primary technical distinction between these parts is the viewing angle specification. The C10974_GT4-WW delivers 60°/62° wide angle distribution, while the C10973_GT4-W provides 36°/38° viewing angle. Selection between these parts must be based on the specific optical requirements of the application. Narrower viewing angles concentrate light intensity over a smaller area; wider angles distribute light over a broader field.

Inventory & Availability:

The C10973_GT4-W maintains active product status with 758 units in stock, whereas the C10974_GT4-WW is obsolete with limited remaining inventory (981 units). For new designs or long-term production requirements, the active substitute part is the appropriate selection.

Compliance & Environmental:

Both parts carry identical environmental ratings (MSL 1 - Unlimited) and regulatory certifications, permitting direct substitution from a compliance perspective.

Frequently Asked Questions (FAQ)

Q: Can the C10973_GT4-W directly replace the C10974_GT4-WW in existing assemblies?

A: Mechanical and material compatibility is confirmed. Both parts share identical lens diameter (35mm), mounting type (adhesive), material (acrylic), and LED count (4). The viewing angle differs: C10973_GT4-W provides 36°/38° versus C10974_GT4-WW's 60°/62°. Substitution is valid only if the optical angle specification of your application permits the narrower viewing angle of the substitute part.

Q: What is the significance of the viewing angle difference?

A: Viewing angle determines the light distribution pattern. The 60°/62° angle of the main part creates a wider light spread, while the 36°/38° angle of the substitute concentrates light over a narrower field. Application-specific optical requirements must be evaluated before substitution.

Q: Are there packaging differences between these parts?

A: The C10974_GT4-WW is specified with "-" packaging notation, while the C10973_GT4-W is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts support the same LED manufacturers?

A: Yes. Both the C10974_GT4-WW and C10973_GT4-W are compatible with Lumileds and Nichia LED sources.

Q: What is the product status implication for long-term supply?

A: The C10974_GT4-WW is obsolete, indicating discontinued production. The C10973_GT4-W maintains active status with ongoing availability. For designs requiring long-term component supply, the active substitute is the recommended selection.

Q: Are environmental and compliance ratings identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry MSL rating 1 (Unlimited), and share identical ECCN and HTSUS classifications.
