Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9T08052A4530BAHFT is determined by strict equivalence across the following critical parameters:

• Resistance value: 453 Ohms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power rating: 0.125W minimum
• Package: 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Termination count: 2 terminations
• Moisture sensitivity: MSL 1 or better

The substitute parts identified maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in circuit applications. Variations in temperature coefficient, operating temperature upper limits, and compliance certifications are noted but do not prevent substitution where the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07453RL is the primary direct substitute. This YAGEO part maintains identical electrical specifications and package dimensions while offering active product status and ROHS3 compliance. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) provides superior stability across the operating temperature range. Packaging is supplied as Tape & Reel (TR), standard for production environments.

TNPW0805453RBETA serves as an upgrade alternative from Vishay Dale. This military-grade thin film resistor delivers the same resistance, tolerance, and power rating with equivalent temperature coefficient performance. The slightly reduced maximum seated height (0.022" versus 0.024") and narrower operating temperature upper limit (-55°C to 125°C versus 155°C) must be evaluated against specific application requirements. REACH status is affected, requiring compliance verification for regulated markets.

Selection between these substitutes depends on compliance requirements, supply chain availability, and application temperature specifications. Both maintain functional equivalence for the core 453 Ohm ±0.1% 1/8W 0805 thin film resistor specification.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07453RL directly replace 9T08052A4530BAHFT in existing designs?

A: Yes. Both parts share identical resistance (453 Ohms), tolerance (±0.1%), power rating (0.125W), package (0805), and physical dimensions. The improved temperature coefficient and active product status make this the preferred direct substitute.

Q: What is the significance of the temperature coefficient difference between the main part and substitutes?

A: The main part specifies ±100ppm/°C while both substitutes offer ±25ppm/°C. This means substitute parts exhibit four times better resistance stability across temperature variations. For applications operating across the full -55°C to 155°C range, the substitute parts maintain tighter resistance tolerance.

Q: Is TNPW0805453RBETA suitable for applications requiring operation above 125°C?

A: No. TNPW0805453RBETA is rated to -55°C ~ 125°C maximum. If your application requires operation up to 155°C, use RT0805BRD07453RL, which is rated to -55°C ~ 155°C.

Q: What does RoHS3 compliance mean for RT0805BRD07453RL?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. This is required for many regulated markets and end-use applications. The main part and TNPW0805453RBETA are RoHS non-compliant.

Q: Are there package or footprint differences between these parts?

A: All three parts use 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). TNPW0805453RBETA has a slightly lower maximum seated height (0.022" versus 0.024"), which is negligible for standard PCB assembly but should be verified for space-constrained designs.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your application tolerates the operating temperature and compliance differences noted. RT0805BRD07453RL is the recommended primary substitute due to active status and broader temperature rating. Verify REACH and RoHS requirements for your target market before final selection.
