9T08052A24R9DAHFT Equivalent & Substitute Parts

Part Overview

The 9T08052A24R9DAHFT is a 24.9 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 relative to active alternatives, identifying equivalent substitute parts is necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A24R9DAHFT is determined by the following parameters:

• Resistance value: 24.9 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 support -55°C to 155°C minimum
• Moisture sensitivity: MSL 1 or better

Two substitute parts meet these criteria:

1. RT0805DRD0724R9L (YAGEO) – Direct functional equivalent with improved specifications
2. TNPW080524R9BETA (Vishay Dale) – Upgrade option with enhanced tolerance and military-grade construction

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD0724R9L is the direct functional replacement. It maintains identical electrical specifications (24.9 Ohms ±0.5%, 0.125W) and package form factor while offering improved temperature coefficient performance (±25ppm/°C vs. ±100ppm/°C). This part is active in production with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete 9T08052A24R9DAHFT.

TNPW080524R9BETA is an upgrade option for applications requiring tighter tolerance control. It provides ±0.1% tolerance (versus ±0.5%) with military-grade construction and equivalent temperature coefficient performance (±25ppm/°C). The operating temperature range is limited to -55°C ~ 125°C, which is acceptable for most applications but does not extend to the full 155°C upper limit of the original part. This part is active in production but carries non-compliant RoHS status.

Selection between these substitutes depends on application requirements: choose RT0805DRD0724R9L for direct replacement with regulatory compliance, or TNPW080524R9BETA if enhanced tolerance specifications are required and the -55°C ~ 125°C temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD0724R9L be used as a direct drop-in replacement for 9T08052A24R9DAHFT?

A: Yes. Both parts share identical resistance (24.9 Ohms), tolerance (±0.5%), power rating (0.125W), and 0805 package dimensions. The substitute offers improved temperature coefficient stability and is actively manufactured.

Q: What is the significance of the temperature coefficient difference between these parts?

A: Temperature coefficient (ppm/°C) indicates resistance value drift across the operating temperature range. The 9T08052A24R9DAHFT exhibits ±100ppm/°C, while both substitutes offer ±25ppm/°C. Lower values indicate better stability. For most general-purpose applications, both are acceptable; precision circuits may benefit from the improved stability of the substitutes.

Q: Why does TNPW080524R9BETA have a lower maximum operating temperature?

A: TNPW080524R9BETA is rated to -55°C ~ 125°C, while the original part extends to 155°C. If your application requires operation above 125°C, RT0805DRD0724R9L is the appropriate choice. For applications within -55°C ~ 125°C, TNPW080524R9BETA is fully compatible.

Q: Are there packaging differences between these parts?

A: The original 9T08052A24R9DAHFT is supplied in bulk packaging. Both substitutes (RT0805DRD0724R9L and TNPW080524R9BETA) are supplied in Tape & Reel format, which is standard for automated assembly. The component form factor (0805) remains identical across all three parts.

Q: What does RoHS compliance mean for component selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the component meets environmental regulations restricting lead and other hazardous materials. RT0805DRD0724R9L is ROHS3 compliant, making it suitable for applications with regulatory requirements. The original part and TNPW080524R9BETA are non-compliant; use these only where RoHS compliance is not mandated.

Q: Can TNPW080524R9BETA replace 9T08052A24R9DAHFT in all applications?

A: TNPW080524R9BETA is compatible for most applications but has two limitations: (1) maximum operating temperature of 125°C versus 155°C, and (2) non-compliant RoHS status. Verify your application's temperature requirements and regulatory environment before selection.
