AOFD-400 Equivalent & Substitute Parts Reference

Part Overview

The AOFD-400 is a configurable switch operator manufactured by IDEC, designed as a pushbutton actuator with round non-illuminated construction for the TWTD series. This component functions as an accessory switch body requiring compatible contact block(s) for complete assembly. The AOFD-400 is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new installations where TWTD series components are specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AOFD-400 is determined by the following critical parameters that must remain consistent:

• Actuator Type: Pushbutton, Round configuration
• Illumination: Non-Illuminated
• Type: Maintained operation
• Panel Cutout Dimensions: 30.5mm (Round)
• Manufacturer: IDEC
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The AOFD-400T qualifies as a direct substitute because it maintains all critical mechanical and electrical parameters. The transition from TWTD series to TWND series represents a product line evolution within IDEC's configurable switch portfolio, with the AOFD-400T offering active product status and equivalent functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The AOFD-400T is the appropriate substitute for the obsolete AOFD-400. Both components maintain identical mechanical interface specifications (30.5mm round panel cutout) and electrical characteristics (maintained pushbutton, non-illuminated, round actuator). The AOFD-400T carries active product status, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance requirements and share equivalent moisture sensitivity ratings. The series transition from TWTD to TWND reflects IDEC's product line consolidation while preserving functional compatibility for switch operator applications requiring contact block integration.

Frequently Asked Questions (FAQ)

Q: Can AOFD-400T directly replace AOFD-400 in existing assemblies?

A: Yes. The AOFD-400T maintains all critical mechanical and electrical parameters: identical 30.5mm round panel cutout, maintained pushbutton operation, non-illuminated configuration, and equivalent contact block interface requirements. Series designation change (TWTD to TWND) reflects product line evolution, not functional incompatibility.

Q: What is the significance of the product status change from Obsolete to Active?

A: The AOFD-400T's active status ensures ongoing manufacturing, availability, and supply chain support. The AOFD-400, classified as obsolete, may face sourcing constraints and limited inventory replenishment. Transition to AOFD-400T provides long-term component availability for new installations and system maintenance.

Q: Are there packaging differences between these parts?

A: The AOFD-400 packaging is not specified in available documentation. The AOFD-400T is supplied in bulk packaging. Packaging format does not affect functional compatibility or mechanical interface specifications.

Q: Do both parts require the same contact block configuration?

A: Yes. Both AOFD-400 and AOFD-400T are configurable switch operators requiring compatible contact block(s) for complete functional assembly. Contact block selection is independent of operator model designation.

Q: Are RoHS and MSL ratings identical?

A: Yes. Both parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental compliance and handling requirements.
