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

Part Overview

The LSTD-2 is a configurable switch lamp component manufactured by IDEC in the HW series. This LED indicator lamp operates at 24V and features white light output. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and component sourcing in applications where the original part is no longer readily available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

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

• Manufacturer Compatibility: Parts must be from IDEC and compatible with the HW series
• Component Type: LED indicator lamp configuration
• Voltage Rating: 24V operation requirement
• Electrical Function: Configurable switch lamp functionality
• Regulatory Compliance: ROHS3 compliance status

The LSRD-2 qualifies as a substitute based on matching manufacturer (IDEC), compatible series designation (HW), identical voltage rating (24V), equivalent component type (LED), and equivalent regulatory compliance (ROHS3). While the LSRD-2 features green LED output rather than white, both parts operate within the same electrical and mechanical framework of the HW series configurable switch lamp platform.

Parameter Comparison

Engineering Selection Recommendations

The LSRD-2 is available as an active product with current manufacturing status and documented inventory, whereas the LSTD-2 is obsolete. Both parts maintain ROHS3 compliance and operate at identical 24V specifications within the IDEC HW series framework. Selection between these parts should be based on application requirements regarding LED color output (white versus green) and current availability through distribution channels. The LSRD-2 represents the active equivalent within the product line.

Frequently Asked Questions (FAQ)

Q: Can the LSRD-2 directly replace the LSTD-2 in existing installations?

A: Both parts share identical voltage ratings (24V), manufacturer (IDEC), series designation (HW), and component type (LED). The primary difference is LED color output. Direct substitution is electrically and mechanically compatible within the HW series framework. Application-specific requirements regarding indicator color must be evaluated.

Q: What is the significance of the product status difference?

A: The LSTD-2 is classified as obsolete, indicating discontinued manufacturing. The LSRD-2 maintains active product status with current production and documented inventory availability, making it the recommended sourcing option for new applications and ongoing component requirements.

Q: Are both parts RoHS compliant?

A: Both the LSTD-2 and LSRD-2 are ROHS3 compliant, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What packaging options are available?

A: The LSRD-2 is supplied in bulk packaging. Packaging specifications for the LSTD-2 were not provided in the technical documentation.
