Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 131A-303G is determined by the following critical parameters:

Primary Compatibility Criteria:

• Mounting Type: Panel Mount with Threaded Base
• Color: Green
• Lens Transparency: Clear
• Number of LEDs: 1
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Secondary Consideration:

• Lens Size: Physical dimensions affect panel cutout compatibility and optical performance

The substitute part 1280932003 (Dialight) satisfies the primary compatibility criteria. However, the lens size differs (14.68mm versus 11.13mm), which represents a mechanical variance that must be evaluated against specific panel mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The 1280932003 (Dialight) is an active substitute for the obsolete 131A-303G. Both components maintain identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected) and share core functional parameters including green color, clear lens transparency, single LED configuration, and panel mount threaded base mounting.

The primary engineering consideration is the lens diameter variance: 14.68mm (1280932003) versus 11.13mm (131A-303G). This 3.55mm difference requires verification against panel cutout specifications and mechanical assembly constraints in the target application.

Both components carry MSL Rating 1 (Unlimited moisture sensitivity), indicating equivalent environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1280932003 directly replace the 131A-303G in existing assemblies?

A: Direct replacement depends on panel cutout dimensions. The 1280932003 has a larger lens diameter (14.68mm versus 11.13mm). Panel mounting holes and cutouts must accommodate this size difference. Threaded base compatibility is equivalent.

Q: Are there regulatory compliance differences between these parts?

A: No. Both components are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements.

Q: What is the significance of the different lens styles (Domed Top versus Stovepipe Top)?

A: Lens style affects optical appearance and light diffusion characteristics. The domed top (131A-303G) provides a convex profile, while the stovepipe top (1280932003) provides a cylindrical profile. Selection depends on aesthetic and optical requirements specific to the application.

Q: Is the 1280932003 available in sufficient quantity?

A: Yes. The 1280932003 is listed as Active product status with 980 pieces in stock, compared to 898 pieces for the obsolete 131A-303G.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both components carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
