Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD2262F10 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 22.6 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package format: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height - Seated (Max): 0.024" (0.60mm)
• Number of terminations: 2

Material & Composition:

• Thin film construction
• Moisture resistant

Compliance:

• RoHS3 Compliant
• REACH Unaffected

A substitute part must maintain identical resistance, tolerance, package dimensions, and composition. The power rating may be equal to or greater than the original specification. Product status (active vs. obsolete) and additional certifications (such as AEC-Q200) do not disqualify a part from substitution but may provide enhanced availability or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD2262F10 is a direct substitute for the RN732ATTD2262F10. Both components share identical electrical specifications (22.6 kOhms ±1%, ±10ppm/°C), mechanical dimensions (0805 package), and material composition (thin film, moisture resistant).

The RN73R2ATTD2262F10 offers the following advantages:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain stability.
• Higher Power Rating: The 0.125W (1/8W) rating exceeds the original 0.1W (1/10W) specification, providing additional thermal margin in applications.
• Automotive Certification: AEC-Q200 qualification indicates compliance with automotive reliability standards, beneficial for applications requiring enhanced quality assurance.
• Compliance: Both components maintain ROHS3 compliance and REACH unaffected status.

Selection of the RN73R2ATTD2262F10 is appropriate for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD2262F10 be used as a direct replacement for the RN732ATTD2262F10?

A: Yes. Both components have identical resistance (22.6 kOhms), tolerance (±1%), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), package format (0805), and physical dimensions. The substitute's higher power rating (0.125W vs. 0.1W) is compatible with the original application.

Q: What is the difference between the RN732ATTD2262F10 and RN73R2ATTD2262F10?

A: The primary differences are product status and power rating. The RN732ATTD2262F10 is obsolete with a 0.1W rating, while the RN73R2ATTD2262F10 is active with a 0.125W rating and includes AEC-Q200 automotive certification. Electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both components use the 0805 (2012 Metric) package with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and a maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on PCBs designed for 0805 resistors.

Q: Does the higher power rating of the substitute affect circuit performance?

A: No. A higher power rating does not alter electrical performance. The 0.125W rating of the RN73R2ATTD2262F10 provides additional thermal capacity without changing resistance, tolerance, or frequency response characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD2262F10 and RN73R2ATTD2262F10 are ROHS3 compliant and REACH unaffected.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability for automotive applications. The RN73R2ATTD2262F10 meets this standard, though both parts are suitable for general industrial and consumer applications.
