Substitute Part Grouping Explanation

Substitution of the ALD29902DN-A-240V is determined by strict equivalence across the following parameters:

• Manufacturer: IDEC (same manufacturer ensures design and quality consistency)
• Physical Size: 30MM form factor (ensures mechanical compatibility with existing panel cutouts and mounting)
• Operation Type: Illuminated momentary pushbutton (functional requirement)
• Voltage Rating: 240V (electrical compatibility with system voltage)
• Contact Configuration: 2NC (two normally closed contacts, as specified in substitute description)
• RoHS Compliance: ROHS3 (regulatory requirement maintained)
• Moisture Sensitivity Level: 1 (environmental tolerance equivalent)

The ALD2QM402DNUA meets all these criteria and is derived from the base product number ALD2QM402, confirming design lineage and functional compatibility.

Engineering Selection Recommendations

The ALD2QM402DNUA is the direct substitute for the obsolete ALD29902DN-A-240V based on the following engineering criteria:

• Both components share identical electrical ratings (240V, illuminated momentary operation)
• Both maintain ROHS3 compliance and equivalent environmental specifications (MSL 1)
• The substitute part is currently in active production status, ensuring long-term availability and supply chain reliability
• Identical ECCN and HTSUS classifications confirm regulatory equivalence
• Both components are manufactured by IDEC, maintaining design consistency and quality standards
• The 30MM form factor ensures direct mechanical compatibility with existing installations

Selection of ALD2QM402DNUA eliminates obsolescence risk while preserving full functional and electrical compatibility.
