Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805510KBETA is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 510 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Composition: Thin Film (exact match required)

Mechanical Compatibility Requirements:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) (exact match required)
• Height - Seated (Max): 0.022" (0.55mm) (exact match required)
• Number of Terminations: 2 (exact match required)

Power Rating Consideration: Substitute parts may have equal or higher power ratings than the main part (0.125W minimum). A higher power rating does not disqualify a substitute, as it provides additional thermal margin without affecting electrical performance in the circuit.

Operating Temperature Range: The main part operates from -55°C to 125°C. Substitute parts with extended upper temperature limits (such as -55°C to 175°C) are acceptable and provide enhanced performance capability.

Parameter Comparison

Engineering Selection Recommendations

TNPW0805510KBEEA qualifies as a direct substitute for TNPW0805510KBETA based on identical electrical and mechanical parameters. Both parts are manufactured by Vishay Dale, maintain the same 510 kOhms resistance value with ±0.1% tolerance, and are housed in identical 0805 (2012 Metric) packages.

The substitute part offers the following additional attributes:

• Higher power rating (0.26W vs. 0.125W) provides increased thermal capacity
• Extended operating temperature range (-55°C to 175°C vs. -55°C to 125°C)
• ROHS3 compliance (vs. RoHS non-compliant main part)
• AEC-Q200 automotive qualification
• Anti-sulfur and moisture-resistant construction
• Higher inventory availability (4455 units vs. 1049 units)

Selection between these parts depends on application requirements for compliance certifications, operating temperature limits, and environmental resistance specifications. Both parts are active products with confirmed availability.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805510KBEEA be used as a direct replacement for TNPW0805510KBETA?

A: Yes. Both parts share identical resistance (510 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), composition (thin film), and package dimensions (0805 / 2012 Metric). The substitute part has a higher power rating and extended temperature range, which do not create compatibility issues in circuits designed for the main part.

Q: What is the difference in power rating between these parts?

A: The main part is rated at 0.125W (1/8W), while the substitute is rated at 0.26W. The higher power rating of the substitute indicates greater thermal dissipation capability. In applications where the main part operates within its 0.125W limit, the substitute will perform identically with additional thermal margin.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.022" (0.55mm). They are mechanically interchangeable in PCB layouts designed for 0805 (2012 Metric) packages.

Q: What is the significance of the extended operating temperature range in the substitute part?

A: The substitute part operates from -55°C to 175°C, compared to -55°C to 125°C for the main part. This extended upper temperature limit provides additional performance margin in high-temperature applications. If your circuit operates within the main part's temperature range, both parts will perform identically.

Q: Does the substitute part's AEC-Q200 rating affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates the substitute part has undergone additional reliability testing. This certification does not alter electrical or mechanical compatibility; it only confirms the part meets automotive industry reliability requirements.

Q: What is the difference in RoHS compliance status?

A: The main part is RoHS non-compliant, while the substitute is ROHS3 compliant. If your application or region requires RoHS compliance, the substitute part satisfies this requirement. If RoHS compliance is not required, both parts are functionally equivalent.
