Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0603261KBETA is determined by the following critical parameters:

• Resistance value: 261 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package type: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (exact match required)

The substitute part TNPW0603261KBEEA meets all these criteria. While the substitute 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, moisture resistant), these represent improvements that maintain backward compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both TNPW0603261KBETA and TNPW0603261KBEEA are active products from Vishay Dale with identical core electrical specifications. Selection between these parts should be based on application requirements and regulatory compliance:

The TNPW0603261KBEEA offers ROHS3 compliance, whereas the TNPW0603261KBETA is RoHS non-compliant. For applications requiring RoHS compliance, TNPW0603261KBEEA is the appropriate selection.

The TNPW0603261KBEEA includes AEC-Q200 automotive qualification and anti-sulfur, moisture-resistant features. These certifications and features are beneficial for automotive and harsh environment applications but are not required for general-purpose use.

The extended operating temperature range of TNPW0603261KBEEA (-55°C to 175°C) provides additional thermal margin compared to TNPW0603261KBETA (-55°C to 125°C). For applications operating near the upper temperature limit, TNPW0603261KBEEA is the preferred choice.

The higher power rating of TNPW0603261KBEEA (0.21W versus 0.1W) provides additional thermal headroom and does not compromise compatibility with circuits designed for the 0.1W specification.

Frequently Asked Questions (FAQ)

Q: Can TNPW0603261KBEEA be used as a direct replacement for TNPW0603261KBETA?

A: Yes. Both parts share identical resistance (261 kOhms), tolerance (±0.1%), package (0603), composition (thin film), temperature coefficient (±25ppm/°C), and termination configuration (2). The substitute meets or exceeds all electrical and mechanical specifications of the original part.

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

A: The primary differences are power rating (0.21W versus 0.1W), operating temperature range (-55°C to 175°C versus -55°C to 125°C), RoHS compliance status (ROHS3 Compliant versus non-compliant), and additional features in the substitute (anti-sulfur, AEC-Q200 automotive qualification, moisture resistant).

Q: Are the physical dimensions identical?

A: Both parts use the 0603 (1608 Metric) package with identical height (0.022" maximum seated height). Length and width are nominally equivalent: TNPW0603261KBETA measures 0.063" L × 0.033" W, while TNPW0603261KBEEA measures 0.061" L × 0.033" W. These minor dimensional variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Does the higher power rating of TNPW0603261KBEEA affect circuit performance?

A: No. A higher power rating does not alter electrical performance. The substitute will operate identically to the original part in circuits designed for 0.1W dissipation, with the benefit of additional thermal margin.

Q: Which part should be selected for new designs?

A: For new designs, TNPW0603261KBEEA is recommended due to ROHS3 compliance, AEC-Q200 qualification, and extended operating temperature range, provided these features do not introduce cost or supply constraints.

Q: Are there any moisture sensitivity concerns?

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