Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A64R9DAHFT is determined by the following critical parameters:

• Resistance value: 64.9 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:

RT0805DRD0764R9L (YAGEO, Active) – Direct equivalent with improved temperature coefficient and RoHS3 compliance.

TNPW080564R9BETA (Vishay Dale, Active) – Upgrade option with tighter tolerance (±0.1%) and military-grade specifications, with modified operating temperature range and height specifications.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD0764R9L is the primary direct substitute. It maintains identical electrical specifications (64.9 Ohms ±0.5%, 0.125W) and mechanical compatibility (0805 package, 0.60mm height). The improved temperature coefficient (±25ppm/°C vs. ±100ppm/°C) provides enhanced stability. RoHS3 compliance makes this part suitable for applications requiring regulatory compliance. Active product status ensures long-term availability.

TNPW080564R9BETA is an upgrade option for applications requiring tighter tolerance (±0.1%) and military-grade specifications. The reduced operating temperature range (-55°C to 125°C) must be verified against application requirements. The lower seated height (0.022" vs. 0.024") is compatible with standard 0805 footprints. Active product status supports sustained supply. RoHS non-compliance status should be evaluated against project requirements.

Selection between RT0805DRD0764R9L and TNPW080564R9BETA depends on regulatory compliance needs, tolerance requirements, and operating temperature specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD0764R9L be used as a direct replacement for 9T08052A64R9DAHFT?

A: Yes. Both parts share identical resistance (64.9 Ohms), tolerance (±0.5%), power rating (0.125W), and package (0805). Mechanical dimensions are equivalent. The improved temperature coefficient of RT0805DRD0764R9L provides superior performance stability.

Q: What is the key difference between RT0805DRD0764R9L and TNPW080564R9BETA?

A: TNPW080564R9BETA offers tighter tolerance (±0.1% vs. ±0.5%) and military-grade construction. However, its operating temperature range is limited to -55°C to 125°C, compared to -55°C to 155°C for RT0805DRD0764R9L. Verify application temperature requirements before selection.

Q: Are there any physical compatibility concerns with these substitutes?

A: All three parts use the 0805 (2012 Metric) package and are mechanically compatible with standard 0805 footprints. TNPW080564R9BETA has a slightly lower seated height (0.022" vs. 0.024"), which does not affect PCB assembly compatibility.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is a regulatory requirement for many markets and applications. RT0805DRD0764R9L is RoHS3 compliant, while both 9T08052A64R9DAHFT and TNPW080564R9BETA are RoHS non-compliant. Verify compliance requirements for your target market and application.

Q: Which substitute should I choose for new designs?

A: For new designs, RT0805DRD0764R9L is recommended due to active product status, RoHS3 compliance, and improved temperature coefficient. TNPW080564R9BETA is suitable if military-grade specifications and tighter tolerance are required and the reduced operating temperature range is acceptable.
