RT1206FRE07174KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07174KL is a 174 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate enhanced performance characteristics such as improved tolerance or automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07174KL is determined by the following critical parameters:

• Resistance Value: Must be 174 kOhms (exact match required)
• Package Format: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• Power Rating: Must meet or exceed 0.25W requirement
• Tolerance: ±1% or better acceptable for direct substitution
• Compliance: ROHS3 and REACH compliance required

Two substitute parts meet these criteria with enhanced specifications:

ERA-8AEB1743V (Panasonic Electronic Components) — Upgrade substitute with improved tolerance (±0.1%) and automotive AEC-Q200 qualification.

RNCF1206BKC174K (Stackpole Electronics Inc) — Manufacturer-recommended substitute with enhanced power rating (0.333W), improved tolerance (±0.1%), and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Performance Tier): Both ERA-8AEB1743V and RNCF1206BKC174K are suitable direct substitutes for the RT1206FRE07174KL. All three parts maintain identical resistance values, package formats, and operating temperature ranges. Both substitute parts are ROHS3 compliant and carry unlimited moisture sensitivity ratings.

Performance Enhancement Consideration: ERA-8AEB1743V provides improved tolerance specification (±0.1% versus ±1%) with a lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), beneficial for precision analog circuits.

RNCF1206BKC174K offers increased power dissipation capability (0.333W versus 0.25W) while maintaining the same temperature coefficient as the original part, suitable for applications requiring thermal margin.

Automotive Applications: Both substitute parts carry AEC-Q200 automotive qualification, whereas the original RT1206FRE07174KL does not. Selection of either substitute is required for automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1743V replace RT1206FRE07174KL in any application? A: Yes. ERA-8AEB1743V meets all critical substitution parameters: identical 174 kOhms resistance, 1206 package format, thin film composition, and -55°C to 155°C operating range. The improved ±0.1% tolerance is backward compatible with designs specified for ±1%.

Q: What is the primary advantage of RNCF1206BKC174K? A: RNCF1206BKC174K provides 33% higher power rating (0.333W versus 0.25W) while maintaining all other electrical specifications. This additional thermal headroom is beneficial in high-dissipation circuit nodes.

Q: Are both substitutes suitable for automotive applications? A: Yes. Both ERA-8AEB1743V and RNCF1206BKC174K carry AEC-Q200 automotive qualification. The original RT1206FRE07174KL does not have this certification.

Q: Will the physical dimensions affect PCB assembly? A: All three parts use the 1206 (3216 Metric) package with compatible footprints. Minor dimensional variations (length 3.05mm to 3.20mm, height 0.65mm to 0.70mm) are within standard PCB design tolerances and do not require layout modifications.

Q: Which substitute offers the best temperature stability? A: ERA-8AEB1743V provides superior temperature stability with ±25ppm/°C coefficient compared to ±50ppm/°C for both the original part and RNCF1206BKC174K. This is advantageous for precision measurement and analog signal conditioning circuits.

Q: Can I use these substitutes interchangeably in production? A: Yes, provided your design specifications permit the enhanced tolerance and power ratings. Both substitutes are Active status components with identical compliance certifications (ROHS3, REACH Unaffected).
