Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW040256R0BETD is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 56 Ohms
• Tolerance: ±0.1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.063W
• Operating Temperature Range: Equal to or exceeding -55°C ~ 125°C
• Features and certifications: May differ based on application requirements
• RoHS and REACH compliance: May differ

The TNPW040256R0BEED qualifies as a direct substitute based on matching all mandatory parameters while offering enhanced power rating (0.13W), extended operating temperature range (-55°C ~ 175°C), and additional certifications (AEC-Q200, Anti-Sulfur, Moisture Resistant).

Parameter Comparison

Engineering Selection Recommendations

TNPW040256R0BETD is appropriate for applications requiring military-grade specifications with standard operating temperature range (-55°C ~ 125°C) and standard power dissipation (0.063W).

TNPW040256R0BEED is appropriate for applications requiring:

• Extended operating temperature range up to 175°C
• Higher power dissipation capability (0.13W)
• Automotive qualification (AEC-Q200)
• ROHS3 compliance
• Anti-sulfur and moisture-resistant characteristics

Both parts maintain identical electrical performance (56 Ohms ±0.1%, ±25ppm/°C) and mechanical compatibility (0402 package, identical dimensions). Selection between these parts depends on compliance requirements, thermal environment, and power dissipation needs of the specific application.

Frequently Asked Questions (FAQ)

Q: Can TNPW040256R0BEED replace TNPW040256R0BETD in all applications?

A: Yes, from an electrical and mechanical standpoint. The substitute part matches all mandatory parameters (resistance, tolerance, package, composition, temperature coefficient) and exceeds minimum requirements for power rating and operating temperature range. However, compliance and certification differences must be evaluated against specific application requirements.

Q: What is the difference in power rating between these parts?

A: TNPW040256R0BETD is rated at 0.063W (1/16W), while TNPW040256R0BEED is rated at 0.13W. The substitute part can dissipate approximately twice the power. This difference does not affect compatibility in applications operating within the original part's power specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts are 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). They are mechanically interchangeable on PCB layouts.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard. TNPW040256R0BEED meets this certification, making it suitable for automotive applications. The main part does not carry this certification.

Q: How do the operating temperature ranges differ?

A: TNPW040256R0BETD operates from -55°C to 125°C. TNPW040256R0BEED extends the upper limit to 175°C. Both maintain the same lower temperature limit of -55°C. The substitute part is suitable for higher-temperature environments.

Q: What does RoHS compliance mean for component selection?

A: TNPW040256R0BETD is RoHS non-compliant, while TNPW040256R0BEED is ROHS3 compliant. Applications subject to RoHS regulations must use the compliant substitute part. Non-regulated applications may use either part.
