Equivalent & Substitute Parts for 9T08052A30R9DAHFT

Part Overview

The 9T08052A30R9DAHFT is a 30.9 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 availability through standard procurement channels, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure project timelines are not compromised.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A30R9DAHFT is determined by the following mandatory parameters:

• Resistance value: 30.9 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 encompass -55°C to 155°C or be compatible with application requirements
• Moisture sensitivity: MSL 1 or equivalent

Two substitute parts meet these criteria:

Direct Equivalent: RT0805DRD0730R9L (YAGEO) — Same specifications with improved temperature coefficient and active product status.

Upgrade Alternative: TNPW080530R9BETA (Vishay Dale) — Enhanced tolerance (±0.1%) with military-grade construction, same package and resistance value.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD0730R9L is the direct equivalent substitute. It maintains identical electrical specifications while offering improved temperature coefficient performance (±25ppm/°C vs. ±100ppm/°C). This part carries active product status and ROHS3 compliance, making it suitable for new designs and procurement continuity. The packaging format (Tape & Reel) is standard for production environments.

TNPW080530R9BETA provides an upgrade path with enhanced tolerance (±0.1% vs. ±0.5%), military-grade construction, and equivalent temperature coefficient. This option is appropriate for applications requiring tighter resistance tolerance and higher reliability standards. The operating temperature range is limited to -55°C ~ 125°C, which must be verified against application requirements if the upper temperature limit of 155°C is critical.

Selection between the two substitutes depends on tolerance requirements and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD0730R9L be used as a direct replacement for 9T08052A30R9DAHFT?

A: Yes. Both parts share identical resistance (30.9 Ohms), tolerance (±0.5%), power rating (0.125W), and package (0805). The RT0805DRD0730R9L offers superior temperature coefficient stability and active product status, making it a suitable direct substitute.

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

A: RT0805DRD0730R9L maintains the original ±0.5% tolerance specification, while TNPW080530R9BETA provides tighter ±0.1% tolerance with military-grade construction. Both have identical temperature coefficients (±25ppm/°C). The TNPW series has a maximum operating temperature of 125°C compared to 155°C for the other options.

Q: Are the substitute parts physically compatible with the original design?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB layout and assembly processes require no modification.

Q: Which substitute should be selected for new production designs?

A: RT0805DRD0730R9L is recommended for standard production applications due to its active status, ROHS3 compliance, and direct specification match. TNPW080530R9BETA is appropriate when enhanced tolerance and military-grade reliability are design requirements.

Q: Does the operating temperature range difference affect substitution?

A: The TNPW080530R9BETA operates to 125°C maximum, while the original and RT0805DRD0730R9L operate to 155°C. Verify application requirements; if sustained operation above 125°C is necessary, TNPW080530R9BETA is not suitable.
