Equivalent & Substitute Parts for A2B-T Neon Lamp

Part Overview

The A2B-T is a neon lamp manufactured by Visual Communications Company (VCC) designed for indicator and display applications. This component is classified as Obsolete, indicating it is no longer in active production. The A2B-T features a clear neon lamp with a round domed top lens, rated for 65VAC and 90VDC operation, with R6.2mm wire terminal leads.

Due to its obsolete status, sourcing original inventory may present supply chain challenges. Identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for maintaining design continuity and ensuring component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A2B-T neon lamp are identified based on strict equivalence of the following critical parameters:

Electrical Compatibility:

• Voltage Rating: 65VAC, 90VDC (exact match required)
• Component Type: Neon Lamp

Mechanical Compatibility:

• Lens Size: R6.2mm (exact match required)
• Lens Style: Round with Domed Top (exact match required)
• Lead Style: Wire Terminal (exact match required)

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part A1B meets all specified electrical and mechanical parameters. Both parts are manufactured by VCC and share identical functional specifications. The primary distinction is product status: A1B is classified as "Not For New Designs," whereas A2B-T is "Obsolete."

Parameter Comparison

Engineering Selection Recommendations

A1B as Direct Substitute for A2B-T:

The A1B neon lamp is electrically and mechanically equivalent to the A2B-T. Both components share identical voltage ratings (65VAC, 90VDC), lens specifications (R6.2mm round domed top), lead configuration (wire terminal), and compliance certifications (ROHS3 Compliant, MSL 1).

Product Status Consideration:

The A2B-T is classified as Obsolete, indicating discontinued production and limited availability. The A1B is classified as "Not For New Designs," indicating it remains available but is not recommended for new product development. For existing designs or legacy system maintenance, A1B provides functional equivalence with superior inventory availability (2718 Pcs versus 1082 Pcs).

Compliance & Certification:

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can A1B be used as a direct replacement for A2B-T in existing applications?

A: Yes. The A1B and A2B-T are electrically and mechanically equivalent. Both operate at 65VAC and 90VDC, feature identical R6.2mm round domed top lenses, and use wire terminal leads. Functional performance in existing circuits is equivalent.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete status indicates the part is no longer manufactured and existing inventory is limited. "Not For New Designs" indicates the part is still available but manufacturers do not recommend its use in new product development. For legacy system support, "Not For New Designs" parts provide better availability than obsolete parts.

Q: Are there packaging differences between A2B-T and A1B?

A: Yes. A1B is supplied in Bag packaging, while A2B-T packaging is not specified in available documentation. Packaging differences do not affect electrical or mechanical compatibility; they relate only to handling and storage logistics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both A2B-T and A1B are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8539.29.4000) classifications.

Q: Which part should be selected for inventory planning?

A: A1B offers significantly higher inventory availability (2718 Pcs) compared to A2B-T (1082 Pcs). For applications requiring component sourcing, A1B provides superior supply chain reliability while maintaining complete electrical and mechanical equivalence.
