LSTD-1 Configurable Switch Lamp LED Red 12V - Equivalent & Substitute Parts

Part Overview

The LSTD-1 is a configurable switch lamp component manufactured by IDEC in the HW series, designed for 12V LED applications with red indicator output. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The LSTD-1 serves as a visual indicator component within configurable switch assemblies and requires direct functional replacement when unavailable from original inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSTD-1 is determined by the following critical parameters:

• Manufacturer compatibility: IDEC brand
• Compatible series: HW series
• Voltage rating: 12V operation
• Component type: LED indicator lamp
• Packaging format: Configurable switch component assembly
• Regulatory compliance: ROHS3 Compliant status

The LSRD-1 qualifies as a substitute based on matching manufacturer (IDEC), compatible series designation (HW), identical voltage specification (12V), and equivalent component category (Configurable Switch Components). Both parts maintain ROHS3 compliance and are designed for integration within the same switch assembly platform.

Parameter Comparison

Engineering Selection Recommendations

The LSRD-1 is the designated substitute for the obsolete LSTD-1 based on manufacturer specification and series compatibility. The LSRD-1 maintains active product status with confirmed inventory availability (1001 pcs), ensuring supply chain continuity. Both components meet ROHS3 compliance requirements and operate at identical 12V specifications, supporting direct functional replacement within HW series switch assemblies. Selection of the LSRD-1 eliminates obsolescence risk while preserving electrical and mechanical compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: Can the LSRD-1 directly replace the LSTD-1 in existing assemblies? A: Yes. Both components are IDEC HW series configurable switch lamps rated for 12V operation with ROHS3 compliance. Mechanical and electrical compatibility is maintained across the substitution.

Q: What is the primary difference between LSTD-1 and LSRD-1? A: The LSTD-1 is classified as obsolete with no active manufacturing, while the LSRD-1 maintains active product status with current inventory availability. Both share identical voltage specifications and series designation.

Q: Are there packaging considerations for the LSRD-1 substitute? A: The LSRD-1 is supplied in bulk packaging format, consistent with standard configurable switch component distribution for the HW series.

Q: Does the LSRD-1 require any design modifications for integration? A: No design modifications are required. The LSRD-1 is engineered as a direct functional equivalent within the IDEC HW series platform.

Q: What compliance certifications apply to the LSRD-1? A: The LSRD-1 maintains ROHS3 compliance, matching the regulatory status of the original LSTD-1 component.
