Key Parameters

Substitute Part Grouping Explanation

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

Primary Compatibility Criteria:

• Mounting Type: Panel Mount with Threaded Base (mechanical interface requirement)
• Color: Amber (optical and application-specific requirement)
• Lens Transparency: Clear (optical performance requirement)
• Number of LEDs: 1 (functional requirement)
• Type: Lens Cap (functional category)

Secondary Compliance Criteria:

• RoHS3 Compliance (regulatory requirement)
• REACH Unaffected status (regulatory requirement)
• MSL Rating 1 (environmental stability requirement)

The substitute part 1280933003 from Dialight satisfies all primary compatibility criteria and secondary compliance requirements. Variations in lens style (domed top versus stovepipe top) and lens diameter (11.13mm versus 14.68mm) represent design differences that may affect optical characteristics and mechanical fit within specific panel mount applications.

Parameter Comparison

Engineering Selection Recommendations

The 1280933003 (Dialight) is an active substitute for the obsolete 131A-303A. Both components meet ROHS3 compliance and REACH regulatory requirements, ensuring suitability for current manufacturing and supply chain requirements.

Selection between these components depends on mechanical fit within the panel mount assembly. The 131A-303A features an 11.13mm diameter lens with domed top geometry, while the 1280933003 features a 14.68mm diameter lens with stovepipe top geometry. These dimensional and stylistic differences may affect:

• Panel cutout diameter requirements
• Visual appearance and light distribution characteristics
• Mechanical clearance in confined panel spaces

Verify panel mount hole diameter and available clearance space before final component selection. The active product status of 1280933003 ensures ongoing availability and supply chain continuity compared to the obsolete 131A-303A.

Frequently Asked Questions (FAQ)

Q: Can the 1280933003 directly replace the 131A-303A in existing assemblies?

A: Direct replacement depends on panel mount hole diameter. The 131A-303A has an 11.13mm lens diameter, while the 1280933003 has a 14.68mm lens diameter. Verify that the panel cutout accommodates the larger diameter before installation.

Q: Are there compliance differences between these components?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1. No compliance barriers exist for substitution.

Q: What is the primary reason for seeking a substitute for the 131A-303A?

A: The 131A-303A is classified as obsolete. The 1280933003 is an active product with confirmed inventory availability, ensuring long-term supply chain viability.

Q: Do these components have different optical characteristics?

A: Both components feature amber color with clear lens transparency for single LED applications. The lens style difference (domed versus stovepipe top) may produce different light distribution patterns depending on the specific LED and optical design requirements.

Q: What packaging format is available for the 1280933003?

A: The 1280933003 is supplied in bulk packaging format.
