Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A2002DAHFT is determined by the following mandatory parameters:

• Resistance value: 20 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum
• Composition: Thin Film
• Tolerance: ±0.5% or better (lower tolerance values are acceptable)
• Operating temperature range: Must encompass -55°C to 155°C or be compatible with application requirements
• Moisture sensitivity: MSL 1 or better

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

RT0805DRD0720KL (Direct Substitute)

This YAGEO part provides direct electrical and mechanical substitution. It maintains identical resistance, tolerance, power rating, and package specifications. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) provides enhanced stability. ROHS3 compliance offers regulatory advantage for new designs. Product status is active with substantial inventory availability (23,102 pcs). This part is the primary recommendation for direct replacement in existing designs.

TNPW080520K0BETA (Upgrade Substitute)

This Vishay Dale military-grade thin film resistor offers superior tolerance (±0.1% versus ±0.5%), matching the temperature coefficient improvement of the direct substitute. Military classification indicates enhanced reliability characteristics. Operating temperature range is limited to -55°C to 125°C, which is acceptable for applications not requiring the full 155°C upper limit of the original part. Height is reduced to 0.022" (0.55mm), providing potential PCB layout advantages. Product status is active. This part is suitable for applications where improved tolerance and reliability specifications justify the operating temperature constraint.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD0720KL be used as a direct replacement for 9T08052A2002DAHFT?

A: Yes. Both parts share identical resistance (20 kOhms), tolerance (±0.5%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). RT0805DRD0720KL is active product with ROHS3 compliance.

Q: What is the key difference between the two substitute parts?

A: RT0805DRD0720KL provides direct electrical and mechanical equivalence. TNPW080520K0BETA offers improved tolerance (±0.1%) and military-grade specifications but has a reduced maximum operating temperature of 125°C instead of 155°C.

Q: Is the reduced operating temperature of TNPW080520K0BETA a limitation?

A: Only if your application requires operation above 125°C. For applications operating within -55°C to 125°C, this part is fully compatible.

Q: Are there packaging differences between these parts?

A: All three parts use 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). TNPW080520K0BETA has slightly reduced seated height (0.022" versus 0.024"), which may provide minor PCB layout benefits.

Q: What is the significance of the temperature coefficient difference?

A: The original part has ±100ppm/°C; both substitutes have ±25ppm/°C. Lower temperature coefficient means resistance value changes less with temperature variations, providing improved stability in temperature-sensitive applications.

Q: Which part should I select for a new design?

A: RT0805DRD0720KL is recommended for new designs due to active product status, ROHS3 compliance, and direct parameter equivalence. TNPW080520K0BETA is suitable if military-grade specifications and improved tolerance are required and the 125°C maximum temperature is acceptable.
