Key Parameters

Substitute Part Grouping Explanation

Substitution of the DNK1105W-33-RR is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 1206 (3216 Metric) surface mount package to ensure PCB footprint compatibility and assembly process alignment.

Mounting Type: Surface mount orientation is required for direct replacement in existing designs.

Manufacturer Consistency: Stanley Electric Co maintains manufacturing standards across its product lines, ensuring electrical and mechanical compatibility within the same manufacturer ecosystem.

Functional Classification: The substitute part must serve LED indication or equivalent discrete LED functionality.

Compliance Requirements: REACH Unaffected status ensures regulatory alignment for the substitute component.

The substitute part TDN1105W-23-RR meets these criteria while offering active product status and improved availability.

Engineering Selection Recommendations

Primary Substitute: TDN1105W-23-RR

The TDN1105W-23-RR is the qualified substitute for the obsolete DNK1105W-33-RR based on the following engineering factors:

Product Status: The substitute part holds Active product status, ensuring long-term availability and continued manufacturing support from Stanley Electric Co. This addresses the primary limitation of the obsolete main part.

Package Equivalence: Both parts utilize the 1206 (3216 Metric) surface mount package, guaranteeing direct PCB footprint compatibility without design modification.

Regulatory Compliance: The substitute maintains REACH Unaffected status consistent with the main part and adds ROHS3 Compliance certification, meeting current environmental and regulatory requirements.

Manufacturer Alignment: Both components are manufactured by Stanley Electric Co, ensuring consistent quality standards, manufacturing processes, and technical support.

Moisture Sensitivity: The substitute operates at MSL 4 (72 Hours), which is more stringent than the main part's MSL 3 (168 Hours). This provides enhanced reliability in moisture-sensitive applications and storage conditions.

Electrical Specifications: The substitute provides documented electrical parameters (1.4V forward voltage, 50mA maximum forward current, 870nm wavelength) enabling precise circuit design validation and performance confirmation.

Frequently Asked Questions (FAQ)

Q: Can TDN1105W-23-RR be used as a direct replacement for DNK1105W-33-RR without PCB modification?

A: Yes. Both parts use the 1206 (3216 Metric) surface mount package, ensuring identical PCB footprint compatibility. No layout or design changes are required.

Q: What is the primary reason for substitution?

A: The DNK1105W-33-RR is obsolete and no longer manufactured. The TDN1105W-23-RR is an active product from the same manufacturer, ensuring continued availability and supply chain stability.

Q: Are there compliance differences between the two parts?

A: Both parts maintain REACH Unaffected status. The substitute adds ROHS3 Compliance certification, meeting current environmental standards. The main part's compliance status for RoHS is not specified in available documentation.

Q: How do the moisture sensitivity levels differ?

A: The main part is rated MSL 3 (168 Hours), while the substitute is MSL 4 (72 Hours). MSL 4 represents a more conservative moisture sensitivity rating, requiring stricter handling and storage protocols but providing enhanced reliability in moisture-prone environments.

Q: What electrical parameters should be verified during circuit design with the substitute?

A: The substitute operates at 1.4V typical forward voltage with a maximum forward current of 50mA. The 870nm wavelength and 30° viewing angle should be confirmed as compatible with the original application's optical and electrical requirements.

Q: Is the substitute suitable for the same operating temperature range?

A: The substitute is rated for -30°C to 85°C operation. If the original application requires operation outside this range, compatibility must be verified against the main part's undocumented temperature specifications.

Q: What is the packaging format for the substitute?

A: The TDN1105W-23-RR is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations.
