Equivalent & Substitute Parts for 9T08052A53R6DAHFT

Part Overview

The 9T08052A53R6DAHFT is a 53.6 Ohm ±0.5% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W). Manufactured by YAGEO under the RT series, this component is classified as obsolete. Due to its obsolete status and limited long-term availability, identifying equivalent and substitute parts is necessary to ensure design continuity and supply chain reliability for new production runs and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the 9T08052A53R6DAHFT is determined by strict equivalence in the following parameters:

• Resistance value: 53.6 Ohms (exact match required)
• Tolerance: ±0.5% or better (tighter tolerance acceptable)
• Power rating: 0.125W minimum
• Package: 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Operating temperature range: Must support -55°C to 155°C minimum
• Moisture sensitivity: MSL 1 or better

Two substitute parts meet these criteria:

Direct Substitute: RT0805DRD0753R6L (YAGEO RT series) — functionally equivalent with improved temperature coefficient and active product status.

Upgrade Substitute: TNPW080553R6BETA (Vishay Dale TNPW series) — enhanced tolerance specification with military-grade construction.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD0753R6L is the primary direct substitute. It maintains identical electrical specifications while offering improved temperature coefficient performance (±25ppm/°C vs. ±100ppm/°C), active product status, and ROHS3 compliance. This part is recommended for new designs and production transitions where RoHS compliance is required.

TNPW080553R6BETA is an upgrade substitute suitable for applications requiring enhanced tolerance accuracy (±0.1% vs. ±0.5%). It provides military-grade construction and superior temperature stability. Selection of this part is appropriate when tighter resistance tolerance is a design requirement. Note that the operating temperature upper limit is 125°C, which is 30°C lower than the original specification; verification against application requirements is necessary.

For legacy system maintenance where the original 9T08052A53R6DAHFT must be preserved, RT0805DRD0753R6L offers the closest functional match with superior reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD0753R6L be used as a direct replacement for 9T08052A53R6DAHFT?

A: Yes. Both parts share identical resistance (53.6 Ohms), tolerance (±0.5%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). RT0805DRD0753R6L additionally provides improved temperature coefficient and active product status.

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

A: RT0805DRD0753R6L maintains the ±0.5% tolerance specification of the original part. TNPW080553R6BETA offers tighter tolerance at ±0.1% with military-grade construction. TNPW080553R6BETA has a maximum operating temperature of 125°C, which is lower than the original 155°C specification.

Q: Are all three parts physically identical?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height specifications are similar: 9T08052A53R6DAHFT and RT0805DRD0753R6L are 0.024" maximum, while TNPW080553R6BETA is 0.022" maximum. All are compatible with standard 0805 PCB footprints.

Q: Which part should be selected for new production?

A: RT0805DRD0753R6L is recommended for new production due to active product status and ROHS3 compliance. TNPW080553R6BETA is appropriate if enhanced tolerance accuracy is required by the design specification.

Q: Is moisture sensitivity a concern for any of these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns. Standard handling and storage practices apply.
