Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805511RBETA is determined by the following critical parameters:

• Resistance value: 511 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)

The identified substitute part TNPW0805511RBEEA maintains all critical electrical and mechanical parameters. Variations in power rating, operating temperature range, and compliance certifications do not disqualify substitution when the core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW0805511RBETA and TNPW0805511RBEEA are active production parts with identical core electrical and mechanical specifications. Selection between these parts depends on application-specific requirements:

The TNPW0805511RBETA is suitable for military applications requiring the specified military-grade designation and operating within the -55°C to 125°C temperature range.

The TNPW0805511RBEEA provides enhanced environmental compliance through ROHS3 certification and automotive AEC-Q200 qualification. The extended operating temperature range to 175°C and higher power rating of 0.26W offer additional design margin. Anti-sulfur and moisture-resistant features provide enhanced reliability in harsh environments.

Both parts are manufactured by Vishay Dale and share identical package dimensions, footprint, and MSL rating, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805511RBEEA be used as a direct replacement for TNPW0805511RBETA?

A: Yes. Both parts share identical resistance (511 Ohms), tolerance (±0.1%), composition (thin film), temperature coefficient (±25ppm/°C), and 0805 package dimensions. Electrical and mechanical compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are power rating (0.125W vs. 0.26W), operating temperature range (-55°C to 125°C vs. -55°C to 175°C), RoHS compliance status (non-compliant vs. ROHS3 compliant), and feature set (military vs. automotive AEC-Q200 with anti-sulfur and moisture-resistant properties).

Q: Will the higher power rating of TNPW0805511RBEEA affect circuit performance?

A: No. A higher power rating does not degrade performance in applications designed for lower power dissipation. The substitute part will operate within the same electrical parameters and thermal characteristics as the original part in standard applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 0805 (2012 Metric) package format with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.022" (0.55mm). PCB footprints are interchangeable.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For military specifications, use TNPW0805511RBETA. For automotive or applications requiring RoHS3 compliance and extended temperature operation, use TNPW0805511RBEEA.
