LSTD-2 Configurable Switch Lamp LED Red 24V - Equivalent & Substitute Parts

Part Overview

The LSTD-2 is a configurable switch lamp component manufactured by IDEC in the HW series. This LED lamp unit is designed for 24V operation with red light output and is classified as an obsolete product. The LSTD-2 serves as a visual indicator component within configurable switch assemblies. Due to its obsolete status, identification of functionally compatible substitute components is necessary for system maintenance, repair, and redesign applications where continued availability cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSTD-2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Manufacturer: IDEC
• Compatible Series: HW
• Voltage Rating: 24V
• Component Type: LED
• Packaging Format: Bulk

The substitute part LSRD-2 maintains compatibility with the LSTD-2 through shared manufacturer origin (IDEC), series designation (HW), and identical voltage specification (24V). Both components are LED-type configurable switch lamps designed for 24V applications within the same product family. The LSRD-2 is classified as an active product, providing continued availability and supply chain reliability compared to the obsolete LSTD-2.

Parameter Comparison

Engineering Selection Recommendations

For LSTD-2 Replacement Applications:

The LSRD-2 is the designated manufacturer substitute for the obsolete LSTD-2. Both components share identical voltage specifications (24V), manufacturer origin (IDEC), series classification (HW), and component category (Configurable Switch Components). The LSRD-2 maintains active product status, ensuring supply chain continuity and availability for new production and field replacement scenarios.

Compliance Considerations:

The LSTD-2 is certified as ROHS3 compliant. The LSRD-2 substitute maintains compatibility within the same IDEC HW series platform. Both components carry identical ECCN classification (EAR99) and are subject to the same regulatory framework for export and distribution.

Inventory and Availability:

Current inventory status shows 1110 pieces of LSTD-2 available as new original stock. The LSRD-2 substitute maintains 895 pieces in active inventory, supporting both immediate replacement needs and long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Why is the LSTD-2 listed as obsolete?

A: The LSTD-2 has reached end-of-life status within IDEC's product portfolio. The LSRD-2 represents the active continuation within the same HW series, maintaining functional compatibility for 24V LED lamp applications.

Q: Are LSTD-2 and LSRD-2 mechanically interchangeable?

A: Both components are classified as configurable switch lamps within the IDEC HW series with identical 24V voltage specifications and bulk packaging format. Mechanical compatibility is determined by the shared series designation and component category.

Q: What is the voltage requirement for both components?

A: Both the LSTD-2 and LSRD-2 operate at 24V. This identical voltage specification is a primary substitution criterion.

Q: Are there RoHS compliance differences between these parts?

A: The LSTD-2 is explicitly ROHS3 compliant. RoHS compliance status for the LSRD-2 is not specified in the available technical data. Verification with IDEC is recommended for applications requiring documented RoHS certification.

Q: What is the base product number for these components?

A: The base product number is LSTD-2, with LSRD-2 designated as the active substitute within the same product family.

Q: Are both components available in bulk packaging?

A: Yes. Both the LSTD-2 and LSRD-2 are supplied in bulk packaging format, suitable for production assembly and field service applications.
