• Lamp type: Neon
• Lamp color: White

Mechanical Compatibility:

• Panel cutout shape: Round
• Panel cutout dimensions: 0.31" (7.87mm)
• Lens style: Round with Flat Top
• Termination style: Wire Leads - 4.6" (116.84mm)

Regulatory & Environmental Compliance:

• RoHS3 Compliance
• Moisture Sensitivity Level 1

The substitute part 2120A4 maintains identical electrical and mechanical specifications across all parameters listed above, confirming direct substitutability within the 2120A series.

Parameter Comparison

Engineering Selection Recommendations

The 2120A4 is a direct functional equivalent to the 2120AX4 across all electrical, mechanical, and regulatory parameters. Both components are manufactured by VCC within the same 2120A series and maintain identical specifications for voltage, lamp type, color, panel cutout dimensions, lens configuration, and termination style.

Product Status Consideration: The 2120AX4 is classified as Obsolete, while the 2120A4 is classified as Not For New Designs. This distinction indicates that 2120A4 remains available in inventory (1284 Pcs) but is not recommended for new design implementations. For existing systems requiring the 2120AX4, the 2120A4 provides functional continuity during the transition period.

Compliance Status: Both parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with current regulatory requirements and environmental handling standards.

Packaging Difference: The 2120A4 is supplied in Bag packaging, whereas the 2120AX4 packaging specification is not provided. This represents the only documented difference between the two parts and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 2120A4 be used as a direct replacement for the 2120AX4?

A: Yes. The 2120A4 is electrically and mechanically identical to the 2120AX4. Both components operate at 105V ~ 125V AC, feature white neon lamps, and share identical panel cutout dimensions (0.31" / 7.87mm), lens style (round with flat top), and wire lead termination (4.6" / 116.84mm). All regulatory certifications and environmental ratings are equivalent.

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

A: Obsolete status indicates the 2120AX4 is no longer manufactured and has reached end-of-life. Not For New Designs status for the 2120A4 indicates the part is still available but should not be incorporated into new product designs. For maintenance and repair of existing systems, the 2120A4 provides functional continuity.

Q: Does packaging affect the substitution decision?

A: Packaging does not affect electrical or mechanical performance. The 2120A4 is supplied in Bag packaging. If specific packaging requirements exist for your application, this should be confirmed with your procurement process, but it does not impact component functionality.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2120AX4 and 2120A4 are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), confirming compatibility with current environmental and regulatory standards.

Q: What parameters must match for substitution eligibility?

A: Substitution requires matching across voltage rating (105V ~ 125V AC), lamp type (Neon), lamp color (White), panel cutout shape and dimensions (Round, 0.31" / 7.87mm), lens style (Round with Flat Top), and termination style (Wire Leads - 4.6" / 116.84mm). The 2120A4 meets all these criteria.
