LED Replacement T-2 Telephone Slide 120PSBLS-NWW Equivalent & Substitute Parts

Part Overview

The 120PSBLS-NWW is an LED lamp replacement designed for T-2 telephone slide applications operating at 120V with a standard telephone slide base. This component is manufactured by Visual Communications Company (VCC) and is classified as Active product status with 909 units in current inventory. The 120PSBLS-NWW serves as a direct replacement for multiple T-2 telephone slide base lamps in general purpose lighting applications. Identifying equivalent and substitute parts is necessary to ensure supply chain continuity, optimize procurement options, and maintain compatibility across production environments where multiple equivalent part numbers may be acceptable for the same functional requirement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 120PSBLS-NWW is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Size / Dimension: T-2
• Voltage - Forward (Vf) (Typ): 120V
• Base Type: Telephone Slide Standard
• Color: White
• Configuration: Single
• Applications: General Purpose Lighting

The substitute part 120PSBL-NWW meets all mandatory matching parameters and is therefore classified as a parametric equivalent. Both parts are manufactured by VCC, operate at identical voltage specifications, utilize the same telephone slide standard base, and are designed for identical application contexts. The primary distinction between the main part and substitute lies in the series designation (120PSBLS versus 120PSBL), which reflects internal VCC product line organization without affecting functional compatibility or electrical performance in the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the 120PSBLS-NWW and 120PSBL-NWW are Active status products manufactured by VCC with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the following engineering considerations:

Inventory Availability: The substitute part 120PSBL-NWW maintains higher current inventory (992 units) compared to the main part 120PSBLS-NWW (909 units), which may influence procurement decisions for high-volume applications or extended lead time mitigation.

Compliance Certification: Both parts satisfy identical regulatory requirements including ROHS3 compliance, REACH unaffected status, and equivalent ECCN and HTSUS classifications, ensuring no compliance-related restrictions on substitution.

Functional Equivalence: The parametric alignment across all critical electrical, mechanical, and application-specific parameters confirms that either part number satisfies the functional requirements of T-2 telephone slide base lamp replacement applications at 120V operation.

Frequently Asked Questions (FAQ)

Q: Can the 120PSBL-NWW substitute for the 120PSBLS-NWW in all applications?

A: Yes. The 120PSBL-NWW is a parametric equivalent meeting all mandatory matching criteria: identical T-2 size, 120V voltage specification, telephone slide standard base type, white color, single configuration, and general purpose lighting application classification. Both parts are manufactured by VCC and carry identical compliance certifications.

Q: What is the difference between the 120PSBLS series and 120PSBL series?

A: The series designation reflects internal VCC product line organization. From an engineering and functional perspective, both series designations identify parts with identical electrical specifications, mechanical dimensions, base types, and application suitability. The series difference does not impact substitution eligibility or performance.

Q: Are there any voltage or base type restrictions when substituting these parts?

A: No. Both the main part and substitute operate at 120V and utilize the telephone slide standard base. Substitution is valid only when the application requires these exact specifications. Parts with different voltage ratings or base types are not interchangeable.

Q: What packaging format is available for these parts?

A: Both the 120PSBLS-NWW and 120PSBL-NWW are supplied in Bulk packaging format.

Q: Do these parts meet current environmental and regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, confirming compliance with current environmental and regulatory requirements applicable to electronic components.

Q: Which part should be selected if both are available?

A: Selection may be based on inventory availability, procurement lead times, or internal part number standardization requirements. From a technical and compliance perspective, both parts are functionally equivalent and interchangeable.
