9T08052A39R2DBHFT Equivalent & Substitute Parts

Part Overview

The 9T08052A39R2DBHFT is a 39.2 Ohms ±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 channels, identifying equivalent and substitute parts is necessary for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A39R2DBHFT is determined by the following critical parameters:

• Resistance value: 39.2 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 ~ 155°C minimum

The identified substitutes meet these core electrical and mechanical requirements. RT0805DRE0739R2L is a direct equivalent from the same manufacturer with improved specifications. TNPW080539R2BETA is an upgrade option offering superior tolerance and temperature coefficient performance.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRE0739R2L is the primary direct substitute. It maintains identical electrical specifications while offering improved temperature coefficient performance (±50ppm/°C vs. ±100ppm/°C) and is ROHS3 compliant. This part is active in production and available in standard tape and reel packaging.

TNPW080539R2BETA serves as an upgrade option for applications requiring superior tolerance (±0.1%) and temperature stability (±25ppm/°C). This military-grade thin film resistor from Vishay Dale is active and available. Note that the operating temperature upper limit is 125°C, which is 30°C lower than the original specification. This part is suitable only for applications operating within -55°C ~ 125°C range.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE0739R2L be used as a direct replacement for 9T08052A39R2DBHFT?

A: Yes. Both parts share identical resistance (39.2 Ohms), tolerance (±0.5%), power rating (0.125W), and 0805 package. RT0805DRE0739R2L offers improved temperature coefficient and is ROHS3 compliant. Electrical performance is equivalent or superior.

Q: What is the key difference between the two substitutes?

A: RT0805DRE0739R2L is a direct equivalent from YAGEO with matching specifications. TNPW080539R2BETA is a Vishay Dale military-grade upgrade with tighter tolerance (±0.1%) and better temperature coefficient (±25ppm/°C), but operates to 125°C maximum instead of 155°C.

Q: Are the physical dimensions identical across all three parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height varies slightly: 9T08052A39R2DBHFT and RT0805DRE0739R2L are 0.024" maximum, while TNPW080539R2BETA is 0.022" maximum. This difference is negligible for standard PCB assembly.

Q: Which substitute should be selected for new designs?

A: RT0805DRE0739R2L is recommended for new designs as it is active in production, ROHS3 compliant, and offers improved specifications. TNPW080539R2BETA is suitable only if the application requires military-grade performance and operates within -55°C ~ 125°C.

Q: Are there any compliance considerations?

A: RT0805DRE0739R2L is ROHS3 compliant, making it suitable for applications with RoHS requirements. Both the original part and TNPW080539R2BETA are RoHS non-compliant. REACH status is unaffected for all three parts.
