Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805620RBETA is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value must be 620 Ohms
• Tolerance must be ±0.1% or tighter
• Temperature coefficient must be ±25ppm/°C or better
• Power rating must meet or exceed 0.125W

Mechanical Compatibility Requirements:

• Package format must be 0805 (2012 Metric)
• Physical dimensions must match: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height - Seated (Max) must not exceed 0.022" (0.55mm)
• Two terminations required

Material & Composition:

• Thin film construction required

The TNPW0805620RBEEA meets all substitution criteria. While it features enhanced power rating (0.26W vs. 0.125W), extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 125°C), and additional certifications (AEC-Q200, anti-sulfur, moisture resistant), the core electrical and mechanical parameters remain compatible for direct substitution in applications designed for the TNPW0805620RBETA.

Parameter Comparison

Engineering Selection Recommendations

TNPW0805620RBETA Selection Criteria:

• Military-grade thin film resistor for defense and aerospace applications
• RoHS non-compliant status requires verification against project compliance mandates
• REACH Affected classification necessitates regulatory review for end-use applications
• Suitable for applications operating within -55°C to 125°C temperature envelope
• 910 units currently in stock

TNPW0805620RBEEA Selection Criteria:

• Automotive-grade component with AEC-Q200 certification for automotive and industrial applications
• ROHS3 Compliant and REACH Unaffected status for unrestricted commercial deployment
• Anti-sulfur and moisture-resistant features provide enhanced environmental protection
• Extended operating temperature range (-55°C to 175°C) accommodates high-temperature applications
• 5830 units currently in stock with greater availability

Selection between these parts depends on regulatory compliance requirements, application environment, and temperature operating range. Both parts maintain identical core electrical and mechanical specifications for direct substitution within their respective compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805620RBEEA be used as a direct replacement for TNPW0805620RBETA in existing designs?

A: Yes. Both parts share identical resistance value (620 Ohms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package format (0805), and physical dimensions. The substitute part exceeds the original specification in power rating (0.26W vs. 0.125W) and operating temperature range (-55°C to 175°C vs. -55°C to 125°C), making it functionally compatible for direct substitution in PCB layouts and circuit designs.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Power rating—TNPW0805620RBEEA is rated at 0.26W compared to 0.125W for the original; (2) Operating temperature range—TNPW0805620RBEEA extends to 175°C versus 125°C; (3) Certifications—TNPW0805620RBEEA includes AEC-Q200 automotive qualification and anti-sulfur/moisture-resistant features; (4) Compliance—TNPW0805620RBEEA is ROHS3 Compliant and REACH Unaffected, while the original is RoHS non-compliant and REACH Affected.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. Both parts are packaged in 0805 (2012 Metric) format with identical physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.022" / 0.55mm). They are mechanically interchangeable on standard PCB layouts without modification.

Q: Which part should be selected for automotive applications?

A: TNPW0805620RBEEA is the appropriate choice for automotive applications due to its AEC-Q200 certification, ROHS3 compliance, and REACH Unaffected status. The original TNPW0805620RBETA is classified as military-grade and lacks automotive qualification.

Q: What is the impact of the higher power rating on circuit performance?

A: The higher power rating (0.26W) of TNPW0805620RBEEA does not negatively impact circuit performance. It provides additional thermal margin and allows the component to dissipate more power without exceeding temperature limits. For applications designed for 0.125W dissipation, the substitute operates well within its thermal envelope.

Q: Are both parts available in the same packaging format?

A: Yes. Both TNPW0805620RBETA and TNPW0805620RBEEA are supplied in Tape & Reel (TR) packaging, standard for automated PCB assembly processes.
