165 kOhms ±0.5% 1/8W 0805 Chip Resistor Equivalent & Substitute Parts (9T08052A1653DAHFT)

Part Overview

The 9T08052A1653DAHFT is a 165 kOhms thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package. This part is classified as obsolete, making equivalent and substitute components necessary for ongoing production and design requirements. The resistor is rated for 0.125W (1/8W) power dissipation with ±0.5% tolerance and operates across the temperature range of -55°C to 155°C. Identifying compatible substitutes ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9T08052A1653DAHFT is determined by the following critical parameters:

• Resistance Value: Must be 165 kOhms
• Package / Case: Must be 0805 (2012 Metric)
• Power Rating: Must be 0.125W (1/8W) minimum
• Composition: Thin film construction
• Number of Terminations: Must be 2
• Moisture Sensitivity Level: MSL 1 or equivalent

Parts meeting these criteria are electrically and mechanically compatible. Tolerance, temperature coefficient, and operating temperature range may vary within acceptable engineering margins. Compliance certifications and product status are secondary considerations that affect supply availability and regulatory requirements but do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD07165KL is the direct equivalent substitute. This YAGEO part maintains identical electrical specifications (165 kOhms ±0.5%, 0.125W) and mechanical compatibility (0805 package). The part is in active production status with improved temperature coefficient performance (±25ppm/°C versus ±100ppm/°C) and achieves ROHS3 compliance, addressing regulatory requirements that the obsolete 9T08052A1653DAHFT does not meet.

TNPW0805165KBETA is an upgrade substitute manufactured by Vishay Dale. This military-grade thin film resistor offers superior tolerance (±0.1% versus ±0.5%) and improved temperature coefficient (±25ppm/°C). The part is in active production and maintains full package and power rating compatibility. The operating temperature range is limited to -55°C to 125°C, which is narrower than the main part's -55°C to 155°C range. This part is suitable for applications requiring higher precision and military-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD07165KL be used as a direct replacement for 9T08052A1653DAHFT?

A: Yes. Both parts share identical resistance value (165 kOhms), tolerance (±0.5%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). Mechanical and electrical compatibility is confirmed. RT0805DRD07165KL is in active production, whereas 9T08052A1653DAHFT is obsolete.

Q: What is the difference between the direct substitute and the upgrade substitute?

A: RT0805DRD07165KL is a direct equivalent with matching specifications. TNPW0805165KBETA is an upgrade offering tighter tolerance (±0.1% versus ±0.5%) and military-grade construction. The upgrade part has a narrower maximum operating temperature (125°C versus 155°C). Select the upgrade only if precision requirements justify the specification change.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Height differences are minimal (0.024" for main and direct substitute, 0.022" for upgrade) and do not affect PCB assembly compatibility.

Q: Does RoHS compliance affect substitution?

A: RoHS compliance is a regulatory requirement, not a functional parameter. RT0805DRD07165KL achieves ROHS3 compliance, making it suitable for applications with RoHS mandates. The main part and upgrade substitute are RoHS non-compliant. Compliance requirements depend on end-use application and regional regulations.

Q: Can TNPW0805165KBETA be used in applications requiring operation above 125°C?

A: No. TNPW0805165KBETA is rated to a maximum of 125°C, whereas the main part and direct substitute are rated to 155°C. For applications requiring operation above 125°C, use 9T08052A1653DAHFT or RT0805DRD07165KL only.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance value drift with temperature change. The main part has ±100ppm/°C; both substitutes have ±25ppm/°C. Lower temperature coefficient means better stability across temperature extremes. For precision applications, the improved temperature coefficient of the substitutes is beneficial.
