Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C10972_GT4-M is determined by the following parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Manufacturer: Ledil
• Series: GT4
• Type: Lens with Integrated Mount
• Lens Size: 35mm Dia
• Number of LEDs: 4
• Lens Style: Round with Flat Top
• Color: Clear
• Material: Acrylic
• Mounting Type: Adhesive
• Compliance: ROHS3 Compliant, REACH Unaffected

Variable Parameters (Allowable Differences):

• Optical Pattern: Medium to Wide
• Viewing Angle: 26°/28° to 36°/38°
• Lens Transparency: Diffused (maintained)
• Product Status: Obsolete to Active

The substitute part C10973_GT4-W maintains all fixed parameters while offering a wider optical pattern and increased viewing angles, making it suitable for applications requiring broader light distribution.

Parameter Comparison

Engineering Selection Recommendations

The C10973_GT4-W serves as the active equivalent for the obsolete C10972_GT4-M within the Ledil GT4 series. Both parts maintain identical mechanical and material specifications, ensuring direct physical compatibility in 4-LED applications with Lumileds and Nichia LED sources.

The primary difference is the optical pattern: C10973_GT4-W provides a wider viewing angle (36°/38°) compared to the medium pattern (26°/28°) of the original part. This wider distribution is suitable for applications requiring increased light spread while maintaining the same lens geometry and mounting interface.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The C10973_GT4-W is currently in active production status with confirmed inventory availability, whereas the C10972_GT4-M is obsolete. For new designs or component replenishment, the C10973_GT4-W is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can C10973_GT4-W be used as a direct replacement for C10972_GT4-M?

A: Yes, within the constraints of optical pattern requirements. Both parts share identical mechanical dimensions (35mm diameter), mounting method (adhesive), lens style (round with flat top), and material composition (acrylic). The C10973_GT4-W provides a wider viewing angle (36°/38° versus 26°/28°), which expands light distribution. Applications requiring the original medium pattern specification may need optical performance validation.

Q: What are the key compatibility factors between these parts?

A: Compatibility is determined by: Ledil manufacturer origin, GT4 series designation, 4-LED configuration, 35mm lens diameter, round flat-top geometry, clear diffused acrylic construction, and adhesive mounting. These parameters are identical between both parts.

Q: Are there compliance differences between the two parts?

A: No. Both C10972_GT4-M and C10973_GT4-W are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited). Regulatory compliance is equivalent.

Q: What is the primary functional difference?

A: The optical pattern differs: C10972_GT4-M is medium pattern (26°/28° viewing angle), while C10973_GT4-W is wide pattern (36°/38° viewing angle). This affects light distribution width but not lens size, mounting, or material properties.

Q: Is packaging different between these parts?

A: The main part C10972_GT4-M is listed with packaging designation "-" (not specified), while C10973_GT4-W is packaged in Bulk. Verify packaging requirements for your procurement process.

Q: Why is C10972_GT4-M classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The C10973_GT4-W remains in active production, making it the recommended selection for ongoing applications and new designs.
