ASLD200 Equivalent & Substitute Parts

Part Overview

The ASLD200 is a configurable switch operator from IDEC's TWTD series, designed as an illuminated selector switch body component. This maintained-type actuator requires separate contact blocks, illumination sources, and lenses for complete assembly. The ASLD200 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

The ASLD0201T8 qualifies as a functional equivalent based on the following critical parameters:

• Manufacturer: Both parts are manufactured by IDEC
• Category: Both are configurable switch components
• Actuator Type: Both are selector-type actuators
• Type: Both are maintained-type switches
• Illumination: Both are illuminated
• Panel Cutout Dimensions: Both require 30.5mm round panel cutouts
• RoHS Compliance: Both meet ROHS3 requirements
• Moisture Sensitivity Level: Both are MSL 1 (Unlimited)
• Required Components: Both require contact blocks, illumination sources, and lenses

The primary difference is the series designation: ASLD200 belongs to the TWTD series, while ASLD0201T8 belongs to the TWND series. Both series share identical mechanical and electrical interface specifications for the switch operator body.

Parameter Comparison

Engineering Selection Recommendations

The ASLD0201T8 is the direct functional equivalent for ASLD200 applications. Selection should be based on the following factors:

Product Status: The ASLD200 is obsolete, while ASLD0201T8 is active. For new designs or system replacements, ASLD0201T8 is the appropriate choice to ensure long-term component availability and supply chain continuity.

Compliance: Both parts meet ROHS3 requirements and carry identical moisture sensitivity ratings, ensuring regulatory compliance across both options.

Mechanical Compatibility: Identical panel cutout dimensions (30.5mm round) ensure direct mechanical substitution without panel modifications.

Series Compatibility: While the parts belong to different series (TWTD versus TWND), the switch operator body specifications are functionally equivalent. Contact block, illumination source, and lens requirements remain consistent between series.

Frequently Asked Questions (FAQ)

Q: Can ASLD0201T8 directly replace ASLD200 in existing installations?

A: Yes. Both parts share identical mechanical interface dimensions (30.5mm round panel cutout), electrical characteristics (maintained selector illuminated actuator), and component requirements (contact blocks, illumination sources, lenses). The series designation change from TWTD to TWND does not affect operator body compatibility.

Q: What is the significance of the series change from TWTD to TWND?

A: The series designation reflects product line evolution within IDEC's configurable switch portfolio. The TWND series represents the active production equivalent of the obsolete TWTD series. Functional specifications for the switch operator body remain unchanged.

Q: Are there packaging differences between these parts?

A: ASLD200 packaging is not specified in available documentation. ASLD0201T8 is supplied in bulk packaging. Packaging format does not affect functional compatibility or performance.

Q: Do both parts require the same contact blocks and illumination components?

A: Yes. Both ASLD200 and ASLD0201T8 require separate contact blocks, illumination sources, and lenses. Compatibility with these components is maintained across both part numbers.

Q: What is the inventory status for these parts?

A: ASLD200 is obsolete with no active inventory. ASLD0201T8 is active with 864 pieces in stock, confirming availability for immediate procurement.
