Substitute Part Grouping Explanation

Substitution of the RN732ATTD1520C10 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 152 Ohms
• Tolerance: ±0.25%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance capability
• RoHS3 compliance

Allowable Variation:

• Power rating may be equal or higher (0.1W or greater)
• Product status may differ (active vs. obsolete)
• Packaging format (bulk vs. tape & reel) may vary
• Additional certifications (AEC-Q200) do not disqualify substitution

The RN73R2ATTD1520C10 meets all mandatory matching criteria while offering higher power rating (0.125W) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The RN73R2ATTD1520C10 serves as a direct functional substitute for the obsolete RN732ATTD1520C10. Both components maintain identical electrical specifications (152 Ohms, ±0.25% tolerance, ±10ppm/°C temperature coefficient) and physical dimensions (0805 package, 2.00mm x 1.25mm).

The substitute part offers the following advantages:

• Active Product Status: The RN73R2ATTD1520C10 is currently in active production, ensuring long-term availability and supply chain continuity.
• Higher Power Rating: The 0.125W (1/8W) rating exceeds the original 0.1W specification, providing additional thermal margin in applications where the original part was rated.
• Automotive Qualification: AEC-Q200 certification indicates compliance with automotive reliability standards, applicable in automotive and high-reliability applications.
• Regulatory Compliance: Both ROHS3 and REACH compliance are maintained.

Selection of the RN73R2ATTD1520C10 is appropriate for all applications previously specified for the RN732ATTD1520C10, with no circuit redesign required.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD1520C10 be used as a direct replacement for the RN732ATTD1520C10?

A: Yes. Both parts share identical resistance (152 Ohms), tolerance (±0.25%), package format (0805), composition (thin film), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part's higher power rating (0.125W vs. 0.1W) does not prevent substitution.

Q: What is the significance of the higher power rating on the substitute part?

A: The RN73R2ATTD1520C10 is rated at 0.125W compared to the original 0.1W. This higher rating indicates greater thermal dissipation capability. In applications where the original part operated at or near its power limit, the substitute provides additional thermal margin. No circuit modification is required.

Q: Does the AEC-Q200 certification on the substitute part affect compatibility?

A: No. AEC-Q200 is an automotive reliability qualification that indicates enhanced testing and quality assurance. Its presence on the substitute part does not create incompatibility; it represents an additional certification level. The part remains suitable for non-automotive applications.

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

A: Yes. Both the RN732ATTD1520C10 and RN73R2ATTD1520C10 are packaged in 0805 (2012 Metric) format with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). PCB layout and footprint remain unchanged.

Q: What is the difference between the packaging formats listed?

A: The RN732ATTD1520C10 is supplied in standard packaging, while the RN73R2ATTD1520C10 is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. Both formats contain identical components; packaging format selection depends on assembly methodology and procurement volume.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage and handling requirements are identical.

Q: What regulatory compliance applies to both parts?

A: Both the RN732ATTD1520C10 and RN73R2ATTD1520C10 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
