Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RN732ATTD1111A10 are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Resistance value: 1.11 kOhms
• Tolerance: ±0.05%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Moisture Resistance: Required
• RoHS3 Compliance: Required

Allowable Variation Parameters:

• Power Rating: Equal or greater than 0.1W
• Temperature Coefficient: Equal or lower absolute value
• Operating Temperature Range: Equal or extended upper limit
• Product Status: Active preferred for long-term availability

Two substitute parts meet these criteria with different capability levels:

Direct Substitute (Same Series): RN73R2ATTD1111A10 maintains identical electrical specifications while offering higher power rating (0.125W) and automotive qualification (AEC-Q200).

Upgrade Substitute (Enhanced Performance): PLTT0805Z1111AGT5 provides superior power handling (0.25W), extended temperature range (-55°C to 215°C), improved temperature coefficient (±5ppm/°C), and additional protective features (anti-corrosive, flame proof, safety rated).

Engineering Selection Recommendations

For Direct Replacement (RN73R2ATTD1111A10):

Select this substitute when procurement of the obsolete RN732ATTD1111A10 is no longer feasible. The RN73R2ATTD1111A10 maintains identical electrical performance with increased power margin (0.125W vs. 0.1W). Active product status ensures long-term availability. AEC-Q200 automotive qualification provides additional reliability assurance. This part is suitable for applications where the original specifications are sufficient and automotive-grade reliability is beneficial.

For Enhanced Performance (PLTT0805Z1111AGT5):

Select this substitute for applications requiring superior thermal performance, extended operating temperature range, or enhanced environmental protection. The 0.25W power rating provides 2.5× margin over the original specification. Improved temperature coefficient (±5ppm/°C) supports precision measurement and signal conditioning circuits. Anti-corrosive and flame-proof features offer additional protection in harsh environments. Extended temperature range (-55°C to 215°C) accommodates high-temperature industrial and automotive applications. Active product status and ROHS3 compliance ensure regulatory compliance and supply chain continuity.

Compatibility Assurance:

Both substitute parts are electrically and mechanically compatible with the original RN732ATTD1111A10 in 0805 package footprints. All three parts share identical resistance value, tolerance, and package dimensions. Substitution requires no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD1111A10 be used as a direct replacement for RN732ATTD1111A10?

A: Yes. Both parts have identical resistance (1.11 kOhms), tolerance (±0.05%), package (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The RN73R2ATTD1111A10 offers higher power rating (0.125W vs. 0.1W), which is a non-limiting improvement. Active product status ensures availability.

Q: What are the key differences between RN73R2ATTD1111A10 and PLTT0805Z1111AGT5?

A: Both are functionally equivalent to the original part. RN73R2ATTD1111A10 is from KOA Speer with 0.125W power rating and AEC-Q200 automotive qualification. PLTT0805Z1111AGT5 is from Vishay Dale with 0.25W power rating, ±5ppm/°C temperature coefficient (vs. ±10ppm/°C), extended temperature range to 215°C, and additional protective features (anti-corrosive, flame proof, safety rated).

Q: Are there any package or footprint differences between these three parts?

A: All three parts use 0805 (2012 Metric) package. Physical dimensions are nearly identical: RN732ATTD1111A10 and RN73R2ATTD1111A10 are 2.00mm × 1.25mm; PLTT0805Z1111AGT5 is 2.03mm × 1.27mm. Height differences are minimal (0.60mm vs. 0.84mm maximum seated height). All are compatible with standard 0805 PCB footprints.

Q: Which substitute should be selected for new designs?

A: For new designs, select based on application requirements. Use RN73R2ATTD1111A10 for standard applications requiring automotive-grade reliability. Use PLTT0805Z1111AGT5 for applications requiring extended temperature range, superior thermal performance, or enhanced environmental protection. Both are active products with assured long-term availability.

Q: Are all three parts RoHS3 compliant?

A: Yes. RN732ATTD1111A10, RN73R2ATTD1111A10, and PLTT0805Z1111AGT5 are all ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What is the significance of the obsolete status of RN732ATTD1111A10?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available from distributors, but long-term supply cannot be assured. Substitution with active products (RN73R2ATTD1111A10 or PLTT0805Z1111AGT5) is recommended for designs requiring sustained component availability.
