Parameter Comparison

Engineering Selection Recommendations

RN73R2ATTD1142A10 (Direct Substitute): This part is the primary equivalent for the RN732ATTD1142A10. It maintains identical electrical specifications (11.4 kOhms, ±0.05% tolerance, ±10ppm/°C temperature coefficient) and operates within the same temperature range (-55°C ~ 155°C). The power rating is increased from 0.1W to 0.125W, providing additional thermal margin without affecting circuit performance. The RN73R2ATTD1142A10 is manufactured by the same supplier (KOA Speer Electronics, Inc.) and carries active product status, ensuring long-term availability. It includes AEC-Q200 automotive qualification, which provides enhanced reliability assurance. This part is suitable for direct replacement in all applications where the original RN732ATTD1142A10 was specified.

PLTT0805Z1142AGT5 (Upgrade Substitute): This part represents an upgraded alternative manufactured by Vishay Dale Thin Film. It matches the core electrical requirements (11.4 kOhms, ±0.05% tolerance) while offering superior performance characteristics. The temperature coefficient is tightened to ±5ppm/°C (compared to ±10ppm/°C), providing improved stability. The operating temperature range extends to 215°C (versus 155°C), and the power rating is increased to 0.25W. Additional features include anti-corrosive and flame-proof construction. This part is appropriate for applications requiring enhanced thermal performance, extended temperature operation, or superior environmental protection. Active product status ensures sustained supply availability.

Both substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD1142A10 be used as a direct replacement for the RN732ATTD1142A10?

A: Yes. The RN73R2ATTD1142A10 maintains identical resistance (11.4 kOhms), tolerance (±0.05%), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). The increased power rating (0.125W versus 0.1W) is a non-limiting enhancement. Both parts use 0805 (2012 Metric) packaging and thin film construction. The primary difference is product status transition from obsolete to active and the addition of AEC-Q200 automotive qualification.

Q: What are the advantages of using the PLTT0805Z1142AGT5 over the RN73R2ATTD1142A10?

A: The PLTT0805Z1142AGT5 offers three key advantages: (1) tighter temperature coefficient (±5ppm/°C versus ±10ppm/°C), providing superior frequency and temperature stability; (2) extended operating temperature range (-55°C ~ 215°C versus -55°C ~ 155°C), enabling use in high-temperature applications; (3) higher power dissipation capability (0.25W versus 0.125W), allowing operation in higher-power circuits. Additional features include anti-corrosive and flame-proof construction.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) package format with identical termination count (2 terminations). Physical dimensions are equivalent: 0.079" L x 0.049" W (2.00mm x 1.25mm) for the main part and direct substitute, with the upgrade substitute at 0.080" L x 0.050" W (2.03mm x 1.27mm). Height differences are minimal (0.024" maximum for main and direct substitute versus 0.033" for upgrade), and all parts fit standard 0805 PCB layouts.

Q: Do the substitute parts maintain RoHS3 compliance?

A: Yes. Both RN73R2ATTD1142A10 and PLTT0805Z1142AGT5 are ROHS3 compliant, matching the original RN732ATTD1142A10 specification. Both parts also maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Which substitute part should be selected for automotive applications?

A: The RN73R2ATTD1142A10 includes AEC-Q200 automotive qualification, making it the appropriate choice for automotive-grade applications. The PLTT0805Z1142AGT5 does not carry explicit automotive certification but offers enhanced environmental protection through anti-corrosive and flame-proof features.

Q: What is the impact of the different temperature coefficients on circuit performance?

A: The RN732ATTD1142A10 and RN73R2ATTD1142A10 both specify ±10ppm/°C temperature coefficient. The PLTT0805Z1142AGT5 specifies ±5ppm/°C, representing a tighter tolerance. For precision analog circuits, timing circuits, or applications with wide operating temperature ranges, the lower temperature coefficient of the PLTT0805Z1142AGT5 provides improved stability and reduced drift over temperature.

Q: Are the substitute parts available in the same packaging formats?

A: The RN732ATTD1142A10 is supplied in bulk packaging. Both substitute parts (RN73R2ATTD1142A10 and PLTT0805Z1142AGT5) are supplied in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly. This packaging difference does not affect electrical compatibility or PCB mounting.
