Key Parameters

Substitute Part Grouping Explanation

Substitution for the AYD302N-B is determined by alignment across the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility and mechanical fit)
• Base Product Series: AYD302 (common platform ensures mechanical and electrical compatibility)
• Form Factor: 30mm pushbutton emergency stop configuration
• Contact Configuration: 2NC (dual normally-closed contacts)
• Actuation Type: Push-pull mechanism
• RoHS Compliance: ROHS3 Compliant (regulatory requirement match)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental tolerance match)
• Trade Classification: HTSUS 8536.50.9035 (confirms product category alignment)

The substitute part AYD302NUB meets all these criteria, representing the active production equivalent within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The AYD302NUB is the direct functional equivalent for the obsolete AYD302N-B. Both components share identical base product designation (AYD302), manufacturer origin (IDEC), and regulatory compliance certifications (ROHS3, EAR99). The substitute part maintains equivalent moisture sensitivity classification and trade code alignment, confirming mechanical and electrical interchangeability within the same application context.

Selection of AYD302NUB is supported by its active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete AYD302N-B.

Frequently Asked Questions (FAQ)

Q: Can AYD302NUB directly replace AYD302N-B in existing installations?

A: Yes. Both components share the AYD302 base product platform, identical RoHS compliance status, and equivalent moisture sensitivity ratings. Mechanical form factor and electrical contact configuration are consistent across the product family.

Q: What is the significance of the packaging difference (- versus Bulk)?

A: Packaging designation indicates the distribution format. The AYD302NUB is supplied in bulk packaging, standard for active production components. This does not affect functional or mechanical compatibility.

Q: Are there any regulatory or compliance considerations when substituting these parts?

A: Both parts maintain ROHS3 compliance and identical ECCN/HTSUS classifications. No additional regulatory review is required for substitution within the same application context.

Q: Why is AYD302N-B listed as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific part number. The AYD302NUB represents the current active production equivalent within the same product family.
