LSTD-1W Equivalent & Substitute Parts

Part Overview

The LSTD-1W is a Configurable Switch Lamp LED manufactured by IDEC, classified as a configurable switch component. This part is designated as Obsolete and is no longer in active production. With 782 pieces currently in stock, the LSTD-1W remains available through existing inventory channels. Due to its obsolete status, identification of active equivalent components is necessary to ensure continued availability and support for new designs or replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSTD-1W is based on functional equivalence within the IDEC configurable switch component family. The primary substitute, LSRD-1, maintains compatibility through the following criteria:

Key Substitution Parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Category: Configurable Switch Components (identical functional classification)
• Component Type: LED-based configurable switch lamp
• Compatible Series: IDEC, HW (ensures mechanical and electrical fit within existing switch assemblies)
• Product Status: Active (LSRD-1 is in active production, addressing obsolescence of LSTD-1W)

The LSRD-1 is the manufacturer-recommended substitute and represents the active-production equivalent within the IDEC configurable switch lamp product line.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Replacement Applications:

The LSRD-1 is the designated manufacturer-recommended substitute for the obsolete LSTD-1W. Selection of the LSRD-1 is appropriate for applications requiring:

• Active production support and long-term availability
• Integration with IDEC HW series switch assemblies
• 12V LED-based configurable switch lamp functionality
• Green LED indication

For Existing Inventory Management:

The LSTD-1W remains available through existing stock (782 pieces). Continued use of LSTD-1W inventory is permissible in applications where the component is already integrated and no design changes are planned. However, for new procurement or design revisions, transition to the LSRD-1 is necessary due to the obsolete status of the LSTD-1W.

Both components share identical Moisture Sensitivity Level classification (Not Applicable) and are manufactured by IDEC, ensuring consistency in supply chain management and technical support.

Frequently Asked Questions (FAQ)

Q: Why is the LSTD-1W listed as obsolete?

A: The LSTD-1W has been discontinued by IDEC and replaced by the active-production LSRD-1 model. Obsolete designation indicates the part is no longer manufactured and will not receive design updates or extended production runs.

Q: Is the LSRD-1 a direct replacement for the LSTD-1W?

A: The LSRD-1 is the manufacturer-recommended substitute and is functionally equivalent within the IDEC configurable switch component family. Both components are designed for use in IDEC HW series switch assemblies.

Q: What are the key differences between LSTD-1W and LSRD-1?

A: The LSRD-1 specifies 12V operation and green LED color, whereas the LSTD-1W does not include these specifications in available documentation. The LSRD-1 is in active production status, while the LSTD-1W is obsolete.

Q: Can I use LSTD-1W and LSRD-1 interchangeably in existing assemblies?

A: Both components are classified as Configurable Switch Components within the IDEC product line and are compatible with IDEC HW series switch assemblies. Mechanical and electrical compatibility is maintained across the substitution.

Q: What packaging options are available for the LSRD-1?

A: The LSRD-1 is supplied in Bulk packaging. The LSTD-1W packaging specification is not documented in available records.

Q: How long will LSTD-1W inventory remain available?

A: Current inventory of 782 pieces is available through existing stock channels. Once inventory is depleted, the LSRD-1 becomes the only available option for new procurement.

Q: Are there any compliance or certification differences between these parts?

A: Both components share identical Moisture Sensitivity Level classification (Not Applicable). No additional compliance or certification differences are documented.
