TNPW06031K69BETA Equivalent & Substitute Parts

Part Overview

The TNPW06031K69BETA is a 1.69 kOhms ±0.1% thin film chip resistor in 0603 (1608 Metric) package rated for 0.1W 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 918 units in stock. Substitute parts may be required due to inventory constraints, application-specific performance requirements, or compliance needs for automotive or moisture-sensitive environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW06031K69BETA is determined by the following critical parameters:

• Resistance Value: Must be 1.69 kOhms
• Tolerance: Must be ±0.1%
• Package Type: Must be 0603 (1608 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• Number of Terminations: Must be 2
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The TNPW06031K69BEEA meets all these criteria and qualifies as a direct substitute. While the BEEA variant offers enhanced power rating (0.21W versus 0.1W), extended operating temperature range (-55°C to 175°C versus -55°C to 125°C), and additional features (anti-sulfur, automotive AEC-Q200 certification, moisture resistant), these represent improvements that maintain backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The TNPW06031K69BEEA serves as a direct functional substitute for the TNPW06031K69BETA. Both parts maintain identical electrical specifications for resistance, tolerance, temperature coefficient, and package geometry. The BEEA variant is ROHS3 compliant, whereas the BETA is RoHS non-compliant. The BEEA includes AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features, making it suitable for automotive and harsh environment applications. The extended operating temperature range of the BEEA (-55°C to 175°C) provides additional thermal margin beyond the BETA specification (-55°C to 125°C). The higher power rating of the BEEA (0.21W versus 0.1W) offers improved thermal headroom without affecting circuit performance in applications designed for the 0.1W specification. Selection between these parts should be based on compliance requirements, environmental conditions, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can TNPW06031K69BEEA replace TNPW06031K69BETA in existing designs?

A: Yes. Both parts share identical resistance value (1.69 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package type (0603), and termination configuration (2). The BEEA variant meets or exceeds all electrical and mechanical specifications of the BETA.

Q: What are the physical differences between these parts?

A: The BETA measures 0.063" L x 0.033" W (1.60mm x 0.85mm), while the BEEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm). Both have identical height (0.022" / 0.55mm maximum). These dimensional variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Does the higher power rating of BEEA affect circuit operation?

A: No. The BEEA's 0.21W rating is a superset of the BETA's 0.1W specification. Circuits designed for 0.1W operation will function identically with the BEEA, which simply provides additional thermal margin.

Q: What is the significance of AEC-Q200 certification on the BEEA?

A: AEC-Q200 is an automotive qualification standard. The BEEA meets automotive reliability and performance requirements, making it suitable for automotive applications. The BETA does not carry this certification.

Q: Are there compliance differences between these parts?

A: Yes. The BEEA is ROHS3 compliant, while the BETA is RoHS non-compliant. Applications subject to RoHS regulations must use the BEEA variant.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling or baking requirements during storage or assembly.
