Substitute Part Grouping Explanation

The ERA-8AEB1740V qualifies as a substitute for the RT1206FRE07174RL based on the following critical parameters:

• Identical resistance value: 174 Ohms
• Identical package format: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Identical termination count: 2
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The ERA-8AEB1740V provides enhanced tolerance specification (±0.1% versus ±1%) and includes automotive AEC-Q200 qualification, representing an upgrade path while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07174RL and ERA-8AEB1740V maintain Active product status and ROHS3 compliance. The ERA-8AEB1740V is suitable for applications requiring automotive-grade reliability through AEC-Q200 qualification. Selection between these parts depends on application requirements: the RT1206FRE07174RL serves general-purpose applications, while the ERA-8AEB1740V is appropriate for automotive and high-reliability environments where tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) specifications are beneficial.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB1740V directly replace the RT1206FRE07174RL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package format (1206), operating temperature range, and RoHS compliance status. The ERA-8AEB1740V provides superior tolerance and temperature coefficient specifications, making it a direct mechanical and electrical substitute.

Q: What is the significance of the ±0.1% tolerance in the ERA-8AEB1740V compared to ±1% in the RT1206FRE07174RL?

A: The ERA-8AEB1740V maintains tighter resistance tolerance, resulting in more precise resistance values across production batches. This specification is relevant for precision analog circuits, measurement instrumentation, and applications where resistance accuracy directly impacts circuit performance.

Q: Does the AEC-Q200 automotive qualification of the ERA-8AEB1740V affect its use in non-automotive applications?

A: No. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. The ERA-8AEB1740V is suitable for any application where the RT1206FRE07174RL is specified, with the added benefit of automotive-grade reliability.

Q: Are there dimensional differences between these parts that affect PCB layout?

A: Dimensional differences are minimal. The RT1206FRE07174RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. The ERA-8AEB1740V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit the standard 1206 package footprint without layout modifications.

Q: What is the temperature coefficient difference and when does it matter?

A: The RT1206FRE07174RL has ±50ppm/°C while the ERA-8AEB1740V has ±25ppm/°C. Lower temperature coefficient means resistance value changes less with temperature variations. This becomes significant in precision circuits, wide temperature range applications, or systems requiring stable gain and timing characteristics across the -55°C to 155°C operating range.
