ASLD3100-1 Equivalent & Substitute Parts

Part Overview

The ASLD3100-1 is a configurable switch operator from IDEC's TWTD series, designed as an illuminated selector switch body component. This part functions as an accessory switch operator requiring separate contact block(s), illumination source, and lens for complete assembly. The ASLD3100-1 is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new installations where TWTD series compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASLD3100-1 is based on the following critical parameters that must remain consistent:

• Manufacturer & Compatible Series: Both parts are IDEC products within compatible configurable switch component families
• Actuator Type & Function: Selector switch with momentary operation
• Illumination Requirement: Illuminated operator configuration
• Panel Cutout Dimensions: 30.5mm round cutout ensures mechanical compatibility
• Environmental Compliance: ROHS3 compliance and MSL 1 rating maintained across substitutes
• Component Architecture: Both require separate contact block(s), illumination source, and lens

The ASLD0314T8 qualifies as a substitute because it maintains these core parameters while transitioning from the obsolete TWTD series to the active TWND series within IDEC's configurable switch product line.

Parameter Comparison

Engineering Selection Recommendations

The ASLD0314T8 is the designated substitute for the obsolete ASLD3100-1. Selection is based on:

• Product Status: The ASLD3100-1 is obsolete; the ASLD0314T8 is active and currently manufactured
• Compliance Continuity: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental performance parity
• Functional Equivalence: Identical mechanical interface (30.5mm round panel cutout), actuator type (selector), operation mode (momentary), and illumination configuration
• Series Transition: The TWND series (ASLD0314T8) represents the active product line continuation within IDEC's configurable switch component portfolio

Frequently Asked Questions (FAQ)

Q: Why is the ASLD3100-1 being replaced? A: The ASLD3100-1 is classified as obsolete. The ASLD0314T8 from the active TWND series provides functional and mechanical equivalence for new designs and system maintenance.

Q: Are the panel cutout dimensions identical? A: Yes. Both the ASLD3100-1 and ASLD0314T8 require a 30.5mm round panel cutout, ensuring direct mechanical compatibility in existing panel installations.

Q: Do both parts require the same auxiliary components? A: Yes. Both parts require separate contact block(s), illumination source, and lens for complete assembly. Compatibility of these auxiliary components should be verified against the TWND series specifications.

Q: Is there a difference in environmental rating? A: No. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, indicating identical environmental performance characteristics.

Q: What is the difference between the TWTD and TWND series? A: The TWTD series (ASLD3100-1) is obsolete. The TWND series (ASLD0314T8) is the active product line. Both series share identical core parameters for selector switch operators with illumination, but TWND represents the current manufacturing standard.

Q: Can I use ASLD0314T8 as a direct replacement in existing systems? A: The ASLD0314T8 maintains mechanical and functional equivalence with the ASLD3100-1. Verification of contact block and illumination source compatibility with the TWND series is required for specific system applications.
