Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW08054K02FEEA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 4.02 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Number of Terminations: 2 (functional equivalence)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1% or better)
• Power Rating: May be equal or higher (0.26W or greater)
• Temperature Coefficient: ±25ppm/°C (matching specification acceptable)
• Operating Temperature Range: May be equal or extended
• Features: Anti-Sulfur and Moisture Resistant features acceptable in substitutes
• Compliance: RoHS3 and MSL Level 1 required

The substitute part PTN0805E4021BST1 meets all mandatory matching parameters and provides improved tolerance (±0.1% vs ±1%) and equivalent power handling within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

The PTN0805E4021BST1 is a qualified substitute for the TNPW08054K02FEEA based on the following criteria:

Electrical Compatibility: Both parts share identical resistance values, temperature coefficients, and thin film composition. The substitute provides superior tolerance performance (±0.1% vs ±1%), which is advantageous for precision circuit applications.

Physical Compatibility: Both parts utilize the 0805 (2012 Metric) package with identical footprints and two terminations, ensuring direct PCB layout compatibility without redesign.

Compliance & Certification: Both parts maintain ROHS3 compliance and MSL Level 1 rating. The substitute retains anti-sulfur and moisture-resistant properties required for reliability in harsh environments.

Power Rating Consideration: The substitute PTN0805E4021BST1 is rated at 0.2W (1/5W), which is lower than the original 0.26W rating. Selection of this substitute requires confirmation that circuit power dissipation does not exceed 0.2W at the resistor location.

Temperature Range Consideration: The substitute operates across -55°C ~ 155°C, which is narrower than the original -55°C ~ 175°C range. Applications requiring operation above 155°C must retain the original TNPW08054K02FEEA.

Automotive Applications: The original part carries AEC-Q200 automotive qualification. The substitute does not list this certification. Automotive applications requiring AEC-Q200 compliance must use the original TNPW08054K02FEEA.

Frequently Asked Questions (FAQ)

Q: Can PTN0805E4021BST1 be used as a direct replacement for TNPW08054K02FEEA?

A: Direct substitution is possible only if circuit power dissipation does not exceed 0.2W and operating temperature does not exceed 155°C. If the application requires AEC-Q200 automotive qualification, the original part must be used.

Q: What is the significance of the tolerance difference (±1% vs ±0.1%)?

A: The substitute provides tighter tolerance, meaning the actual resistance value will be closer to the nominal 4.02 kOhms specification. This is beneficial for precision applications but does not prevent substitution in general-purpose circuits.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use the 0805 (2012 Metric) package. Dimensional variations exist (TNPW08054K02FEEA: 0.079" L x 0.049" W; PTN0805E4021BST1: 0.080" L x 0.050" W), but these fall within standard 0805 package tolerances and do not affect PCB compatibility.

Q: Why does the substitute have a lower power rating?

A: The PTN0805E4021BST1 is rated at 0.2W versus the original 0.26W. This difference reflects the design specifications of each resistor series. Applications must ensure actual power dissipation remains below 0.2W when using the substitute.

Q: Is the substitute suitable for automotive applications?

A: The substitute lacks AEC-Q200 automotive qualification. For automotive applications requiring this certification, the original TNPW08054K02FEEA must be specified.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Tape & Reel (TR) packaging is used for high-volume automated assembly, while Cut Tape (CT) is used for lower-volume or manual assembly. Both contain identical components; packaging format affects handling and assembly processes only.
