Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2150A3 neon panel indicator is determined by strict alignment across the following critical parameters:

Electrical Compatibility:

• Neon lamp type (AC-rated technology)
• Amber lamp color output
• 105V to 125V AC voltage rating

Mechanical Compatibility:

• Round panel cutout shape with 0.31" (7.87mm) diameter
• Round flat-top lens styling
• Wire lead termination at 4.6" (116.84mm) length

Regulatory & Environmental Compliance:

• ROHS3 Compliant status
• REACH Unaffected classification
• Moisture Sensitivity Level 1 (Unlimited)

The 2110A3 meets all specified parameters identically across electrical ratings, mechanical form factor, and regulatory certifications, establishing it as a parametric equivalent substitute for the 2150A3.

Parameter Comparison

Engineering Selection Recommendations

2110A3 as Direct Substitute:

The 2110A3 is a parametric equivalent to the 2150A3 across all specified electrical, mechanical, and regulatory parameters. Both components are classified as "Not For New Designs," reflecting their legacy status within the neon indicator lamp category. Selection between these parts should be based on inventory availability and application continuity requirements rather than technical differentiation.

Current inventory status shows 5,915 units of the 2110A3 available against 1,291 units of the 2150A3, providing supply flexibility for ongoing maintenance and repair operations. Both parts maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment in existing installations.

For applications currently operating with the 2150A3, direct substitution with the 2110A3 requires no circuit modifications, panel cutout alterations, or lead length adjustments. The identical 0.31" (7.87mm) round panel cutout and 4.6" (116.84mm) wire lead configuration ensure mechanical fit without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 2110A3 replace the 2150A3 in existing equipment without modification?

A: Yes. The 2110A3 is a parametric equivalent with identical electrical ratings (105V ~ 125V AC), mechanical form factor (0.31" round cutout, 4.6" wire leads), and lens configuration (amber, clear, round flat-top). No circuit, panel, or wiring modifications are required.

Q: Are there any compliance differences between the 2150A3 and 2110A3?

A: No. Both parts carry identical ROHS3 Compliant and REACH Unaffected certifications. Moisture Sensitivity Level is 1 (Unlimited) for both components.

Q: What determines whether a neon panel indicator can substitute for the 2150A3?

A: Substitution requires matching across: neon lamp type, amber color output, 105V ~ 125V AC voltage rating, round 0.31" (7.87mm) panel cutout, round flat-top lens style, and 4.6" (116.84mm) wire lead termination. Regulatory compliance (ROHS3, REACH) must also align.

Q: Why are both the 2150A3 and 2110A3 marked "Not For New Designs"?

A: This designation indicates both components represent legacy neon indicator technology. They remain available for field replacement and maintenance of existing installations but are not recommended for new product development.

Q: How do I verify mechanical compatibility when substituting the 2110A3 for the 2150A3?

A: Confirm that your panel cutout is round with a 0.31" (7.87mm) diameter and that the 4.6" (116.84mm) wire lead length accommodates your wiring configuration. Both parameters are identical between parts, eliminating compatibility concerns.
