Substitute Part Grouping Explanation

Substitution eligibility for the RN732ATTD2001F25 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Resistance value: 2 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C minimum and 155°C maximum (substitute must meet or exceed)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variations:

• Tolerance: May be equal or tighter (±1% or better)
• Power Rating: May be equal or higher (0.1W or greater)
• Product Status: Active substitutes preferred for obsolete parts
• Compliance: RoHS and REACH status may differ based on application requirements

Two substitute parts meet these criteria with specific trade-offs in tolerance, power rating, and certifications.

Engineering Selection Recommendations

RN73R2ATTD2001F25 (Direct Substitute - Recommended for Most Applications)

The RN73R2ATTD2001F25 is the primary direct substitute for the obsolete RN732ATTD2001F25. Both components share identical resistance, tolerance, package, composition, temperature coefficient, and moisture sensitivity specifications. The RN73R2ATTD2001F25 offers a higher power rating (0.125W vs. 0.1W), providing additional thermal margin in the same physical footprint. This part maintains ROHS3 compliance and includes Automotive AEC-Q200 certification, indicating enhanced reliability qualification. The RN73R2ATTD2001F25 is currently in active production with 1006 units in stock, ensuring long-term availability and supply chain stability.

TNPW08052K00BETA (Upgrade Substitute - Enhanced Tolerance Applications)

The TNPW08052K00BETA from Vishay Dale serves as an upgrade substitute where tighter tolerance specifications are required. This component provides ±0.1% tolerance compared to the ±1% tolerance of the main part, delivering superior precision in applications demanding lower resistance variation. The TNPW08052K00BETA also features a higher power rating (0.125W) and military-grade construction. However, this substitute operates within a reduced temperature range (-55°C to 125°C versus -55°C to 155°C) and is RoHS non-compliant. Selection of this part requires confirmation that the lower maximum operating temperature and RoHS status align with application and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD2001F25 be used as a direct replacement for RN732ATTD2001F25?

A: Yes. Both components share identical electrical specifications (2 kOhms ±1%, ±25ppm/°C), physical package (0805), and thermal operating range (-55°C to 155°C). The RN73R2ATTD2001F25 provides higher power dissipation capability (0.125W vs. 0.1W) within the same package, making it functionally compatible and thermally superior.

Q: What is the key difference between RN73R2ATTD2001F25 and TNPW08052K00BETA?

A: The primary differences are tolerance (±1% vs. ±0.1%), manufacturer (KOA Speer vs. Vishay Dale), maximum operating temperature (155°C vs. 125°C), and compliance status (ROHS3 compliant vs. RoHS non-compliant). The TNPW08052K00BETA is suitable only for applications requiring tighter tolerance and operating below 125°C.

Q: Are all three parts physically interchangeable on a PCB?

A: Yes. All three components use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Height differences (0.024" vs. 0.022") are negligible for standard PCB assembly and do not affect mechanical compatibility.

Q: Which substitute should be selected for new designs?

A: RN73R2ATTD2001F25 is the recommended choice for new designs. It is in active production, ROHS3 compliant, includes automotive qualification (AEC-Q200), and maintains full compatibility with the original specification including the complete -55°C to 155°C operating range.

Q: Can TNPW08052K00BETA be used in applications requiring operation at 155°C?

A: No. The TNPW08052K00BETA maximum operating temperature is 125°C. Applications requiring sustained operation at temperatures above 125°C must use RN73R2ATTD2001F25 or the original RN732ATTD2001F25.

Q: What is the impact of using a ±0.1% tolerance part instead of ±1%?

A: The ±0.1% tolerance provides significantly tighter resistance variation, reducing circuit parameter drift. For a 2 kOhm resistor, ±0.1% tolerance limits variation to ±2 ohms compared to ±20 ohms with ±1% tolerance. This is beneficial for precision analog circuits but unnecessary for general-purpose applications.

Q: Are there RoHS compliance implications when selecting between these substitutes?

A: Yes. RN73R2ATTD2001F25 is ROHS3 compliant, suitable for applications with RoHS requirements. TNPW08052K00BETA is RoHS non-compliant and must not be used in applications subject to RoHS regulations or customer RoHS mandates.
