Substitute Part Grouping Explanation

Substitution eligibility for the TNPW040256R2BETD is determined by the following critical parameters:

• Resistance value: 56.2 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package type: 0402 (1005 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 TNPW040256R2BEED meets all mandatory electrical and mechanical parameters. Differences exist in power rating (0.13W versus 0.063W), operating temperature upper limit (175°C versus 125°C), feature set (anti-sulfur, automotive AEC-Q200, moisture resistant), and compliance certifications (RoHS3 compliant versus RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The TNPW040256R2BEED is a direct electrical and mechanical substitute for the TNPW040256R2BETD. Both components share identical resistance, tolerance, package dimensions, and thermal characteristics. The substitute part offers enhanced compliance status (RoHS3 compliant, REACH unaffected) and automotive qualification (AEC-Q200). The increased power rating (0.13W versus 0.063W) and extended operating temperature range (-55°C to 175°C versus -55°C to 125°C) provide additional design margin without affecting circuit performance in applications designed for the original part.

Selection between these parts depends on regulatory requirements and application environment. Applications requiring RoHS3 compliance or automotive qualification should use TNPW040256R2BEED. Applications with REACH compliance constraints or those operating exclusively below 125°C may use either part based on inventory and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can TNPW040256R2BEED replace TNPW040256R2BETD in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance value (56.2 Ohms ±0.1%), tolerance, package (0402), composition (thin film), temperature coefficient (±25ppm/°C), and physical dimensions. The substitute part is a direct replacement.

Q: What are the differences between these two parts?

A: The primary differences are power rating (0.13W versus 0.063W), maximum operating temperature (175°C versus 125°C), compliance certifications (RoHS3 compliant versus RoHS non-compliant), and feature set (AEC-Q200 automotive qualification and anti-sulfur coating on the substitute).

Q: Does the higher power rating of TNPW040256R2BEED affect circuit operation?

A: No. A higher power rating does not alter electrical performance. The substitute part dissipates power identically to the original part in the same circuit configuration. The increased rating provides additional thermal margin.

Q: Are both parts suitable for automotive applications?

A: TNPW040256R2BEED carries AEC-Q200 automotive qualification. TNPW040256R2BETD does not have this certification. For automotive applications requiring AEC-Q200 compliance, use TNPW040256R2BEED.

Q: What is the significance of RoHS3 compliance?

A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. TNPW040256R2BEED is RoHS3 compliant; TNPW040256R2BETD is not. Applications subject to RoHS3 requirements must use the compliant substitute.

Q: Can these parts be used interchangeably in high-temperature applications?

A: TNPW040256R2BEED supports operation to 175°C, while TNPW040256R2BETD is rated to 125°C. For applications exceeding 125°C, use TNPW040256R2BEED. For applications below 125°C, both parts are suitable.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).
