Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805510RBETA is determined by the following core parameters:

• Resistance value: 510 Ohms
• Tolerance: ±0.1%
• Composition: Thin Film
• Package / Case: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of Terminations: 2
• Temperature Coefficient: ±25ppm/°C

The TNPW0805510RBEEA meets all core substitution criteria. While it features a higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C versus -55°C to 125°C), these represent performance enhancements that do not compromise compatibility. The identical resistance, tolerance, thin film composition, 0805 package, and physical dimensions ensure direct functional equivalence in applications designed for the TNPW0805510RBETA.

Parameter Comparison

Engineering Selection Recommendations

Both the TNPW0805510RBETA and TNPW0805510RBEEA are active production components from Vishay Dale with identical core electrical and mechanical specifications. Selection between these parts should be based on application-specific compliance and environmental requirements.

The TNPW0805510RBETA is designated for military applications and is RoHS non-compliant. The TNPW0805510RBEEA is ROHS3 compliant and carries AEC-Q200 automotive qualification with anti-sulfur and moisture-resistant features, making it suitable for automotive and commercial applications requiring enhanced environmental protection and regulatory compliance.

The higher power rating (0.26W) and extended temperature range (-55°C to 175°C) of the TNPW0805510RBEEA provide additional operational margin without introducing compatibility issues, as the 0805 package and physical dimensions remain identical.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805510RBEEA be used as a direct replacement for TNPW0805510RBETA?

A: Yes. Both parts share identical resistance (510 Ohms), tolerance (±0.1%), composition (thin film), package (0805), physical dimensions, and temperature coefficient (±25ppm/°C). The TNPW0805510RBEEA features higher power rating and extended temperature range, which do not compromise compatibility.

Q: What are the key differences between these parts?

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

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), ensuring identical PCB footprint and assembly compatibility.

Q: Which part should be selected for automotive applications?

A: The TNPW0805510RBEEA is qualified to AEC-Q200 automotive standards and is ROHS3 compliant, making it the appropriate choice for automotive applications.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates high precision thin film construction, ensuring the actual resistance value remains within 510 Ohms ±0.51 Ohms across the specified operating temperature range and environmental conditions.
