Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE071K4L are qualified based on the following substitution criteria:

• Identical resistance value: 1.4 kOhms
• Identical power rating: 0.25W (1/4W)
• Identical package: 1206 (3216 Metric)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Equal or superior tolerance: ±1% or better
• Identical or equivalent compliance: ROHS3 Compliant, REACH Unaffected

The identified substitutes meet or exceed these core parameters. Tolerance improvements (from ±1% to ±0.1%) and additional certifications (AEC-Q200, Anti-Sulfur) represent enhanced specifications that maintain full backward compatibility while offering upgraded performance characteristics for applications requiring higher precision or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

The RT1206FRE071K4L (YAGEO) is suitable for standard general-purpose applications where ±1% tolerance and standard temperature coefficient performance are acceptable.

The ERA-8AEB1401V (Panasonic) provides improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) with AEC-Q200 automotive qualification, making it appropriate for precision-critical circuits or automotive-grade applications requiring enhanced reliability.

The RG3216P-1401-B-T5 (Susumu) combines ±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification, and anti-sulfur construction. The reduced maximum seated height (0.020" vs. 0.026") provides a dimensional advantage for space-constrained layouts. This part is suitable for automotive applications, high-reliability systems, or environments with corrosive atmospheric conditions.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1401V or RG3216P-1401-B-T5 be used as direct replacements for RT1206FRE071K4L?

A: Yes. Both substitute parts maintain identical resistance value, power rating, package, and operating temperature range. The improved tolerance and temperature coefficient represent enhanced specifications that do not compromise backward compatibility. Physical dimensions show minor variations within the 1206 package family; verify PCB layout clearances if space margins are minimal.

Q: What is the significance of ±0.1% tolerance compared to ±1%?

A: Tolerance defines the maximum allowable deviation from the nominal resistance value. ±0.1% tolerance provides tighter resistance accuracy than ±1%, reducing circuit performance variation in precision applications such as measurement instrumentation, signal conditioning, or feedback networks where resistance accuracy directly impacts system performance.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive industry qualification standard for passive components. It certifies that the part meets automotive reliability, temperature cycling, and environmental stress requirements. Parts with AEC-Q200 qualification are suitable for automotive applications and high-reliability systems, though they function equally well in non-automotive applications.

Q: What is the anti-sulfur feature in RG3216P-1401-B-T5?

A: Anti-sulfur construction protects the component from corrosion caused by hydrogen sulfide and other sulfurous compounds in industrial or corrosive environments. This feature extends component lifespan in applications exposed to atmospheric pollution or chemical environments.

Q: Are there physical dimension differences that affect PCB assembly?

A: Minor dimensional variations exist within the 1206 package family. RT1206FRE071K4L measures 3.10mm x 1.60mm with 0.65mm maximum height. ERA-8AEB1401V and RG3216P-1401-B-T5 measure 3.20mm x 1.60mm with 0.70mm and 0.50mm maximum heights respectively. These variations are within standard 1206 package tolerances and do not typically affect standard PCB designs. Verify clearances only in space-constrained applications.

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

A: Yes, provided the application requirements are met. For circuits requiring only standard tolerance performance, any of the three parts is suitable. For precision circuits or automotive applications, the substitute parts with ±0.1% tolerance and AEC-Q200 qualification provide enhanced performance margins.
