Key Parameters

Substitute Part Grouping Explanation

Substitution of the RN732ATTD2003D50 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 200 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Number of Terminations: 2

Allowable Variation Parameters:

• Tolerance: Equal or tighter (±0.5% or better)
• Power Rating: Equal or higher (0.1W or greater)
• Temperature Coefficient: Equal or lower absolute value (±50ppm/°C or better)
• Operating Temperature Range: Must encompass or match the required range
• Moisture Sensitivity Level: Must be MSL 1
• RoHS Compliance: ROHS3 Compliant preferred

Two substitute parts meet these criteria with differing characteristics: one maintains direct equivalence with enhanced automotive qualification, and one provides upgraded tolerance specifications with military-grade construction.

Parameter Comparison

Engineering Selection Recommendations

RN73R2ATTD2003D50 (Direct Equivalent): This KOA Speer Electronics part maintains identical electrical specifications (200 kOhms ±0.5%, ±50ppm/°C) and operating temperature range (-55°C ~ 155°C) as the obsolete RN732ATTD2003D50. The RN73R2ATTD2003D50 offers higher power rating (0.125W vs. 0.1W) and includes automotive AEC-Q200 qualification. Product status is Active with ROHS3 compliance. This part is the primary substitute for direct replacement in applications requiring equivalent performance characteristics.

TNPW0805200KBETA (Upgraded Specification): This Vishay Dale component provides enhanced tolerance (±0.1% vs. ±0.5%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C), suitable for applications requiring higher precision. Power rating is 0.125W, matching the RN73R2ATTD2003D50. Military-grade construction is specified. Operating temperature range is -55°C ~ 125°C, which does not extend to 155°C. Product status is Active. RoHS non-compliance and REACH Affected status require verification against procurement requirements. This part is suitable for precision-critical applications where tolerance and temperature stability are primary concerns.

Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD2003D50 directly replace RN732ATTD2003D50?

A: Yes. Both parts share identical resistance (200 kOhms), tolerance (±0.5%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), package (0805), and composition (thin film). The RN73R2ATTD2003D50 provides equal or superior specifications with higher power rating (0.125W vs. 0.1W) and Active product status.

Q: What are the limitations of TNPW0805200KBETA as a substitute?

A: The TNPW0805200KBETA operates to 125°C maximum, not 155°C. It is RoHS non-compliant and REACH Affected, requiring compliance verification. Use this part only in applications where the reduced temperature range is acceptable and regulatory status is compatible with procurement requirements.

Q: Are all three parts mechanically compatible in 0805 footprints?

A: Yes. All three parts use 0805 (2012 Metric) package with identical length and width (0.079" L x 0.049" W). Height differences are minimal (0.024" vs. 0.022"), presenting no practical assembly or clearance issues.

Q: Which substitute is recommended for new designs?

A: RN73R2ATTD2003D50 is recommended for new designs. It maintains full electrical equivalence, offers Active product status with established supply chain, includes automotive qualification, and maintains ROHS3 compliance. TNPW0805200KBETA is suitable only when precision tolerance and temperature coefficient improvements justify the regulatory and temperature range trade-offs.

Q: What is the significance of MSL 1 rating for all parts?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling. All three parts are equivalent in this regard.
