Substitute Part Grouping Explanation

Substitution of the LSTD-6A is based on functional equivalence within the configurable switch lamp LED component category. The primary substitute part is identified as the LSRD-6, which maintains the same manufacturer (IDEC) and product category classification.

The substitution logic is determined by the following key parameters:

• Manufacturer: Both parts are manufactured by IDEC, ensuring design compatibility within the IDEC product ecosystem
• Category: Both parts belong to the Configurable Switch Components category, confirming functional equivalence
• Component Type: Both parts are LED-based lamp elements for configurable switch applications
• Voltage Rating: The LSRD-6 operates at 6V, which aligns with the voltage class of the original LSTD-6A design
• Product Status: The LSRD-6 maintains active production status, providing reliable long-term availability

Parameter Comparison

Engineering Selection Recommendations

The LSRD-6 is the designated manufacturer-recommended substitute for the obsolete LSTD-6A. This substitution is supported by the following engineering considerations:

Product Status Alignment: The LSRD-6 maintains active production status with IDEC, ensuring continued availability and manufacturing support. The LSTD-6A, classified as obsolete, no longer receives production or technical support from the manufacturer.

Functional Equivalence: Both parts operate within the configurable switch lamp LED component category and are designed for identical application contexts within IDEC control panel systems.

Compliance and Certification: Both parts carry identical Moisture Sensitivity Level (MSL) classification of Not Applicable, indicating equivalent environmental handling requirements.

Inventory Availability: The LSRD-6 maintains active inventory levels (1110 Pcs New Original In Stock) compared to the limited remaining stock of the LSTD-6A (853 Pcs New Original In Stock), providing superior long-term supply chain security.

Frequently Asked Questions (FAQ)

Q: Why is the LSTD-6A classified as obsolete?

A: The LSTD-6A has reached end-of-life status within IDEC's product portfolio. Obsolete classification indicates that the manufacturer no longer produces this component and provides no ongoing technical support.

Q: Is the LSRD-6 a direct replacement for the LSTD-6A?

A: The LSRD-6 is the manufacturer-recommended substitute for the LSTD-6A. Both parts function as configurable switch lamp LED components within the IDEC product family and share the same operational voltage class (6V).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by manufacturer (IDEC), product category (Configurable Switch Components), component type (LED lamp), and voltage rating (6V). The LSRD-6 satisfies all these parameters.

Q: Does the LSRD-6 require different packaging or handling procedures?

A: The LSRD-6 is supplied in Bulk packaging. Both the LSTD-6A and LSRD-6 carry identical Moisture Sensitivity Level (MSL) classification of Not Applicable, indicating equivalent environmental handling requirements.

Q: Can I use remaining LSTD-6A inventory alongside LSRD-6 components in new designs?

A: New designs should specify the LSRD-6 to ensure long-term supply chain continuity and manufacturer support. Existing LSTD-6A inventory may be used for maintenance and repair of legacy systems until depletion.

Q: What is the voltage specification for the LSRD-6?

A: The LSRD-6 operates at 6V, which aligns with the voltage class of the original LSTD-6A design.
