ASD3300-1 Equivalent & Substitute Parts Reference

Part Overview

The ASD3300-1 is a configurable switch body selector component manufactured by IDEC within the TWTD series. This non-illuminated momentary switch is designed for applications requiring selector-type actuation with a 30.5mm round panel cutout. The part is classified as obsolete, necessitating identification of active equivalent components to maintain system functionality and ensure continued availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3300-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: IDEC
• Actuator Type: Selector
• Type: Momentary
• Illumination: Non-Illuminated
• Panel Cutout Dimensions: 30.5mm (Round)
• Requires: Contact Block(s)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Series Compatibility: The ASD3300-1 operates within the TWTD series. Substitute components may operate within compatible IDEC series (such as TWND) provided all electrical and mechanical parameters remain equivalent.

The ASD0335T8 satisfies all mandatory matching parameters while maintaining active product status, making it a valid substitute for the obsolete ASD3300-1.

Parameter Comparison

Engineering Selection Recommendations

The ASD0335T8 is the designated substitute for the obsolete ASD3300-1. Selection is based on the following engineering criteria:

Compliance & Certification: Both components maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL) ratings, ensuring regulatory and environmental compatibility across applications.

Product Status: The ASD3300-1 is obsolete with no continued manufacturing. The ASD0335T8 maintains active product status with confirmed inventory availability (930 Pcs New Original In Stock), ensuring supply chain continuity.

Functional Equivalence: All critical electrical and mechanical parameters are identical: momentary operation, selector actuation, non-illuminated design, and 30.5mm round panel cutout. Both components require contact block(s) for operation, maintaining system architecture compatibility.

Series Transition: While the ASD3300-1 operates within the TWTD series and the ASD0335T8 operates within the TWND series, the parameter alignment confirms functional interchangeability within the IDEC configurable switch component family.

Frequently Asked Questions (FAQ)

Q: Can the ASD0335T8 directly replace the ASD3300-1 in existing installations?

A: Yes. The ASD0335T8 matches all critical parameters: momentary type, selector actuator, non-illuminated design, 30.5mm round panel cutout, and identical contact block requirements. Both components maintain ROHS3 compliance and MSL 1 ratings.

Q: What is the difference between the TWTD and TWND series?

A: The TWTD series (ASD3300-1) is obsolete. The TWND series (ASD0335T8) represents the active equivalent within the IDEC configurable switch component family. Both series share identical electrical and mechanical specifications for this component type.

Q: Are there inventory considerations when transitioning from ASD3300-1 to ASD0335T8?

A: The ASD3300-1 has 937 Pcs in stock (obsolete status). The ASD0335T8 has 930 Pcs in stock (active status). For new designs and long-term applications, the ASD0335T8 is recommended due to active product status and continued manufacturing support.

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

A: Yes. Both the ASD3300-1 and ASD0335T8 require contact block(s) for operation. Contact block selection and configuration remain unchanged during substitution.

Q: What certifications apply to the ASD0335T8?

A: The ASD0335T8 maintains ROHS3 compliance and MSL 1 (Unlimited) rating, identical to the ASD3300-1. ECCN classification is EAR99 with HTSUS code 8538.90.8180.
