Equivalent & Substitute Parts for 131A-303C

Part Overview

The 131A-303C is a lens cap assembly manufactured by Visual Communications Company (VCC), classified as an obsolete product. This clear panel mount threaded lens cap features a round domed top design with an 11.13mm diameter polycarbonate lens. The product is designed for single LED applications requiring panel-mounted threaded base installation.

Due to the obsolete status of the 131A-303C, identification of equivalent substitute parts is necessary for ongoing maintenance, repair, and new design applications where this component specification remains functionally required.

Substitute Part Grouping Explanation

Substitute part identification for the 131A-303C is based on the following allowed parameters:

Primary Matching Criteria:

• Mounting Type: Panel Mount with Threaded Base (required match)
• Type: Lens Cap (required match)
• Color: Clear (required match)
• Number of LEDs: 1 (required match)
• RoHS Status: ROHS3 Compliant (required match)
• MSL Rating: 1 (Unlimited) (required match)

Secondary Consideration:

• Lens Size: 11.13mm Dia (primary specification; substitutes may vary within mechanical envelope constraints)
• Material: Polycarbonate (preferred; alternatives acceptable if optical and mechanical properties align)

The substitute part 1280937003 (Dialight) satisfies the primary matching criteria. Variations in lens size (14.68mm vs. 11.13mm) and lens style (Stovepipe Top vs. Domed Top) represent mechanical differences that must be evaluated against specific application requirements and available panel mounting space.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Product Replacement:

The 131A-303C is classified as obsolete. The 1280937003 (Dialight) is an active product with equivalent regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification) and identical core functional parameters (panel mount threaded base, clear lens cap, single LED application).

Compliance Alignment:

Both parts maintain identical RoHS3 compliance status, MSL rating of 1 (Unlimited), and equivalent export classification. No regulatory barriers exist for substitution from a compliance perspective.

Physical Considerations:

The primary difference between these parts is lens diameter (11.13mm vs. 14.68mm) and lens profile (domed vs. stovepipe). These mechanical variations require verification against available panel mounting space and optical coverage requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1280937003 directly replace the 131A-303C in existing assemblies?

A: Direct replacement depends on panel mounting hole diameter and available space. The 1280937003 has a larger lens diameter (14.68mm vs. 11.13mm). Mechanical fit must be verified before implementation.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. MSL ratings are identical (1 - Unlimited). No regulatory barriers exist for substitution.

Q: What is the difference between domed and stovepipe lens styles?

A: Domed top (131A-303C) provides a convex lens profile. Stovepipe top (1280937003) provides a cylindrical profile. This affects light distribution and aesthetic appearance but does not alter the threaded panel mount interface.

Q: Is the 1280937003 available in the same packaging as the 131A-303C?

A: The 1280937003 is supplied in Bulk packaging. Original packaging specifications for the 131A-303C are not provided in available data. Packaging requirements should be confirmed with procurement specifications.

Q: What inventory status should be considered for procurement?

A: The 131A-303C shows 1003 pieces in stock (obsolete status). The 1280937003 shows 980 pieces in stock (active product). For new designs or long-term applications, the active product status of 1280937003 provides supply chain continuity.
