Substitute Part Grouping Explanation

Substitution of the 9T08052A3003BAHFT is determined by strict equivalence across the following critical parameters:

• Resistance Value: 300 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power Rating: 0.125W, 1/8W (thermal capability)
• Package / Case: 0805 (2012 Metric) (physical and electrical footprint)
• Composition: Thin Film (performance characteristics)
• Number of Terminations: 2 (electrical connectivity)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage)

Substitute parts are grouped into two categories based on product status and compliance profile:

Direct Equivalent (Active Status): RT0805BRD07300KL maintains identical electrical specifications and active product status, providing immediate procurement availability.

Upgrade Alternative (Military Grade): TNPW0805300KBETA offers enhanced specifications with military-grade composition and active status, suitable for applications requiring higher reliability standards.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07300KL is the primary direct equivalent for the 9T08052A3003BAHFT. This YAGEO part maintains identical electrical specifications while offering active product status and ROHS3 compliance. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) provides enhanced stability across the operating temperature range. This substitute is suitable for applications where RoHS compliance is required and procurement of the obsolete 9T08052A3003BAHFT is no longer feasible.

TNPW0805300KBETA is an upgrade alternative for applications requiring military-grade reliability. Manufactured by Vishay Dale, this part features military thin film composition and maintains the same electrical specifications. The reduced maximum seated height (0.022" versus 0.024") and improved temperature coefficient (±25ppm/°C) offer enhanced performance characteristics. Selection of this part is appropriate for high-reliability applications, though REACH compliance status differs from the main part.

Both substitute parts are electrically and mechanically compatible with the original 9T08052A3003BAHFT within the specified parameter constraints. Selection between them depends on procurement availability, compliance requirements, and application-specific reliability standards.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07300KL be used as a direct replacement for 9T08052A3003BAHFT?

A: Yes. Both parts share identical resistance (300 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), and termination count (2). The primary difference is product status: RT0805BRD07300KL is active with ROHS3 compliance, while 9T08052A3003BAHFT is obsolete. Electrical and mechanical compatibility is maintained.

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

A: The 9T08052A3003BAHFT has a temperature coefficient of ±100ppm/°C, while both RT0805BRD07300KL and TNPW0805300KBETA have ±100ppm/°C and ±25ppm/°C respectively. The lower temperature coefficient in the substitute parts indicates improved stability across temperature variations, resulting in more consistent resistance values over the operating temperature range.

Q: Are there packaging differences between these parts?

A: The 9T08052A3003BAHFT packaging specification is listed as "-" (unspecified). Both substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for high-volume SMD component distribution. This packaging format is compatible with automated assembly processes.

Q: What is the significance of the height difference between 9T08052A3003BAHFT and TNPW0805300KBETA?

A: The 9T08052A3003BAHFT has a maximum seated height of 0.024" (0.60mm), while TNPW0805300KBETA is 0.022" (0.55mm). Both heights are within typical 0805 package specifications and are compatible with standard PCB assembly processes. This minor difference does not affect electrical performance or mechanical fit in standard applications.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: RT0805BRD07300KL is ROHS3 compliant and is the appropriate choice for applications requiring RoHS compliance. TNPW0805300KBETA is RoHS non-compliant. The original 9T08052A3003BAHFT is also RoHS non-compliant.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two terminations. They are mechanically and electrically interchangeable at the PCB level.
