ASLD3100-2 Equivalent & Substitute Parts

Part Overview

The ASLD3100-2 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 blocks, illumination sources, and lenses for complete assembly. The ASLD3100-2 is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new installations. Substitute parts must maintain identical electrical characteristics, mechanical compatibility, and panel cutout dimensions to ensure direct functional replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASLD3100-2 is based on the following critical parameters that must remain constant:

• Momentary operation type
• Illuminated selector switch configuration
• 30.5mm round panel cutout dimension
• IDEC manufacturer origin
• ROHS3 compliance requirement
• MSL 1 rating

The ASLD0310T8 qualifies as a functional equivalent because it maintains all critical electrical and mechanical parameters. The primary distinction is the series designation change from TWTD to TWND and the transition from obsolete to active product status, enabling continued supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The ASLD0310T8 is the designated substitute for the obsolete ASLD3100-2. Both parts maintain identical mechanical compatibility with 30.5mm round panel cutouts and equivalent electrical specifications for momentary illuminated selector operation. The ASLD0310T8 carries active product status with confirmed inventory availability (676 pcs), ensuring supply chain continuity. Both parts meet ROHS3 compliance and MSL 1 requirements. The series transition from TWTD to TWND reflects IDEC's product line evolution while preserving functional equivalence. Direct mechanical and electrical substitution is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can ASLD0310T8 directly replace ASLD3100-2 in existing installations?

A: Yes. Both parts share identical panel cutout dimensions (30.5mm round), momentary operation type, illuminated selector configuration, and electrical specifications. No mechanical redesign is required.

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

A: The series designation reflects IDEC's product line organization. The TWND series represents the active equivalent line, while TWTD is obsolete. Functional and mechanical compatibility remains unchanged.

Q: Are there packaging differences between these parts?

A: The ASLD3100-2 packaging is unspecified in available documentation. The ASLD0310T8 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts require the same accessory components?

A: Yes. Both parts require contact blocks, illumination sources, and lenses as separate components. Accessory compatibility is maintained across the substitution.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). The ASLD0310T8 carries ECCN EAR99 classification.
