Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CPF1206B261RE1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 261 Ohms
• Tolerance: ±0.1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Number of Terminations: 2

Compatible Variation Parameters:

• Power Rating: Equal to or greater than 0.125W
• Operating Temperature Range: Must encompass or extend the -55°C to 155°C minimum range
• RoHS and MSL compliance: Must maintain ROHS3 and MSL 1 standards

The identified substitute parts ERA-8AEB2610V and TNPW1206261RBEEA satisfy all mandatory matching parameters while offering enhanced power ratings and extended temperature ranges, making them suitable for direct replacement in applications where the original specification is met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

ERA-8AEB2610V (Panasonic Electronic Components)

This substitute provides a 0.25W power rating, doubling the capacity of the original CPF1206B261RE1 while maintaining identical electrical specifications. The part carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards. Operating temperature range matches the original specification at -55°C to 155°C. The component is ROHS3 compliant with MSL 1 rating. Selection of this part is appropriate for applications requiring automotive-grade reliability or where additional thermal margin is beneficial.

TNPW1206261RBEEA (Vishay Dale)

This substitute offers the highest power rating at 0.52W with extended operating temperature range to 175°C, providing 20°C additional high-temperature capability beyond the original specification. The part incorporates anti-sulfur and moisture-resistant features with AEC-Q200 automotive qualification. ROHS3 and MSL 1 compliance are maintained. Selection of this part is appropriate for high-reliability applications, extended temperature environments, or designs requiring enhanced environmental protection.

Both substitute parts maintain the critical electrical parameters (261 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient) and package compatibility (1206 / 3216 Metric) required for direct substitution. Dimensional variations are within typical manufacturing tolerances for the 1206 package class.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2610V be used as a direct replacement for CPF1206B261RE1?

A: Yes. Both components share identical resistance (261 Ohms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and 1206 package footprint. The ERA-8AEB2610V provides higher power rating (0.25W vs. 0.125W) and maintains the same operating temperature range (-55°C to 155°C). Direct PCB substitution is compatible.

Q: What is the difference between the two substitute parts?

A: ERA-8AEB2610V provides 0.25W power rating with standard thin film construction. TNPW1206261RBEEA provides 0.52W power rating with anti-sulfur and moisture-resistant features, plus extended temperature range to 175°C. Both maintain identical electrical specifications and package compatibility with the original part.

Q: Are there dimensional concerns when substituting these parts?

A: The original CPF1206B261RE1 measures 0.120" L x 0.061" W with 0.026" maximum seated height. Both substitutes measure 0.126" L x 0.063" W. ERA-8AEB2610V has 0.028" maximum seated height; TNPW1206261RBEEA has 0.026" maximum seated height. These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Do the substitute parts maintain RoHS and MSL compliance?

A: Yes. Both ERA-8AEB2610V and TNPW1206261RBEEA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original CPF1206B261RE1 specifications.

Q: Which substitute should be selected for automotive applications?

A: Both substitutes carry AEC-Q200 automotive qualification. ERA-8AEB2610V is suitable for standard automotive environments. TNPW1206261RBEEA is suitable for high-reliability automotive applications requiring extended temperature range and enhanced environmental protection.

Q: Can these parts be used interchangeably in the same design?

A: Yes, within the constraints of power dissipation requirements. If the circuit design requires only 0.125W, all three parts are suitable. If higher thermal margin or extended temperature operation is needed, the substitutes provide enhanced capability while maintaining electrical compatibility.
