TNPW0805470KBETA Equivalent & Substitute Parts

Part Overview

The TNPW0805470KBETA is a 470 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by Vishay Dale, this military-grade component operates across -55°C to 125°C with a temperature coefficient of ±25ppm/°C. The part is currently active in production with 1137 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained while offering enhanced features, improved compliance status, or expanded operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805470KBETA is determined by the following critical parameters:

• Resistance value: 470 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Termination count: 2 (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

The substitute part TNPW0805470KBEEA maintains all critical electrical and mechanical parameters. Differences in power rating (0.26W vs. 0.125W), operating temperature upper limit (175°C vs. 125°C), and compliance certifications represent enhancements rather than deviations from the core specification.

Parameter Comparison

Engineering Selection Recommendations

The TNPW0805470KBEEA qualifies as a direct substitute for the TNPW0805470KBETA based on matching core electrical and mechanical specifications. Selection between these parts depends on application requirements and compliance mandates:

• Applications requiring ROHS3 compliance should specify TNPW0805470KBEEA, which carries ROHS3 Compliant status versus the non-compliant TNPW0805470KBETA.
• Applications requiring AEC-Q200 automotive qualification should specify TNPW0805470KBEEA, which carries AEC-Q200 rating.
• Applications operating above 125°C should specify TNPW0805470KBEEA, which supports -55°C to 175°C operating range.
• Applications with power dissipation requirements exceeding 0.125W should specify TNPW0805470KBEEA, which is rated at 0.26W.
• Applications with no compliance or temperature extension requirements may continue with TNPW0805470KBETA.

Both parts are manufactured by Vishay Dale and maintain identical package footprint, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805470KBEEA replace TNPW0805470KBETA in existing designs?

A: Yes. Both parts share identical resistance (470 kOhms), tolerance (±0.1%), package (0805), temperature coefficient (±25ppm/°C), and physical dimensions. PCB layout and schematic compatibility is maintained. The substitute offers enhanced power rating (0.26W vs. 0.125W), extended operating temperature range (-55°C to 175°C vs. -55°C to 125°C), and improved compliance certifications.

Q: What are the key differences between these parts?

A: The primary differences are power rating, operating temperature upper limit, and compliance status. TNPW0805470KBEEA provides 0.26W power handling versus 0.125W, supports operation to 175°C versus 125°C, includes AEC-Q200 automotive qualification, carries ROHS3 compliance, and features anti-sulfur and moisture-resistant construction. Electrical performance and package dimensions remain identical.

Q: Are these parts pin-compatible?

A: Yes. Both parts have 2 terminations in identical 0805 (2012 Metric) package configuration with matching physical dimensions (0.079" L x 0.049" W, 0.022" max height). Direct PCB substitution is possible without layout modification.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring ROHS3 compliance, automotive qualification (AEC-Q200), or operation above 125°C, specify TNPW0805470KBEEA. For applications with no such requirements, either part is acceptable based on availability and cost considerations.

Q: Do these parts have different moisture sensitivity?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
