Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASLD329940DN-A-240V is based on the following critical parameters:

• Voltage Rating: 240V operational specification
• Product Category: Selector switch functionality
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 (Unlimited)
• Regulatory Classification: ECCN EAR99 and HTSUS 8536.50.9025

The substitute part ASLD32QM440DNUA maintains these core electrical and compliance parameters, enabling direct functional replacement in 240V selector switch applications.

Parameter Comparison

Engineering Selection Recommendations

The ASLD32QM440DNUA is the direct substitute for the obsolete ASLD329940DN-A-240V. Both components share identical voltage ratings (240V), RoHS3 compliance status, and regulatory classifications (ECCN EAR99, HTSUS 8536.50.9025). The substitute part maintains MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility in equivalent environmental conditions.

The key distinction is product status: ASLD32QM440DNUA is active and currently available, whereas ASLD329940DN-A-240V is obsolete. This substitution is appropriate for new designs, system repairs, and component replenishment where the original part is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can ASLD32QM440DNUA directly replace ASLD329940DN-A-240V in existing installations?

A: Yes. Both components are 240V selector switches with identical RoHS3 compliance, MSL 1 rating, and regulatory classifications. Mechanical and electrical compatibility is maintained across these part numbers.

Q: What is the significance of the "3POS" designation in ASLD32QM440DNUA?

A: The 3POS designation indicates a three-position selector switch configuration. This specification is provided in the substitute part documentation and represents the operational mode of the component.

Q: Are there packaging differences between these parts?

A: ASLD329940DN-A-240V is listed with standard packaging, while ASLD32QM440DNUA is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is ASLD329940DN-A-240V classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by IDEC. ASLD32QM440DNUA represents the current active equivalent for this application.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ASLD329940DN-A-240V and ASLD32QM440DNUA meet ROHS3 Compliant standards, ensuring compliance with current environmental and regulatory requirements.
