RT0805FRE071K27L Equivalent & Substitute Parts

Part Overview

The RT0805FRE071K27L is a 1.27 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE071K27L is determined by the following criteria:

Core Compatibility Requirements:

• Resistance value: 1.27 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Allowable Parameter Variations:

• Tolerance: May be equal to or tighter than ±1%
• Power rating: May be equal to or higher than 0.125W
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Moisture sensitivity level: MSL 1 acceptable

The identified substitute parts meet these criteria with enhancements in tolerance accuracy and/or power rating specifications.

Parameter Comparison

Engineering Selection Recommendations

ERA-6AEB1271V (Panasonic Electronic Components): This substitute offers ±0.1% tolerance with AEC-Q200 automotive qualification. The tighter tolerance and lower temperature coefficient (±25ppm/°C) provide enhanced precision. Suitable for applications requiring automotive-grade reliability and higher accuracy than the original specification.

ERA-6AED1271V (Panasonic Electronic Components): This substitute provides ±0.5% tolerance with AEC-Q200 automotive qualification and lower temperature coefficient (±25ppm/°C). Offers improved stability compared to the original part while maintaining the same power rating. Appropriate for automotive applications with moderate tolerance requirements.

RP73PF2A1K27BTDF (TE Connectivity Passive Product): This substitute features ±0.1% tolerance and doubled power rating (0.25W vs. 0.125W) with ±25ppm/°C temperature coefficient. The increased power dissipation capability provides design margin for thermal stress. Suitable for applications where higher power handling or precision is required within the same package footprint.

All three substitutes maintain full mechanical and electrical compatibility with the original RT0805FRE071K27L specification while offering enhanced performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1271V replace RT0805FRE071K27L in any application? A: Yes. ERA-6AEB1271V meets all core compatibility requirements: identical 1.27 kOhms resistance, 0805 package, thin film composition, and operating temperature range. The tighter ±0.1% tolerance and lower temperature coefficient represent improvements over the original ±1% specification.

Q: What is the difference between ERA-6AED1271V and ERA-6AEB1271V? A: Both are Panasonic ERA-6A series with AEC-Q200 qualification and identical package/temperature specifications. The primary difference is tolerance: ERA-6AEB1271V offers ±0.1% while ERA-6AED1271V offers ±0.5%. Selection depends on circuit accuracy requirements.

Q: Why does RP73PF2A1K27BTDF have a higher power rating? A: RP73PF2A1K27BTDF is rated for 0.25W (1/4W) compared to the original 0.125W (1/8W). Despite the same 0805 package dimensions, the TE Connectivity design accommodates higher power dissipation. This provides additional thermal margin in applications approaching the original power limit.

Q: Are all substitutes mechanically identical to RT0805FRE071K27L? A: All substitutes use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly: RT0805FRE071K27L and Panasonic parts are 0.024" (0.60mm) maximum, while RP73PF2A1K27BTDF is 0.026" (0.65mm) maximum. This minimal difference does not affect PCB layout compatibility.

Q: Do all parts meet RoHS and MSL requirements? A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RT0805FRE071K27L specification.

Q: Which substitute is best for automotive applications? A: Both Panasonic ERA-6A series parts (ERA-6AEB1271V and ERA-6AED1271V) carry AEC-Q200 automotive qualification. The original YAGEO RT0805FRE071K27L does not list automotive certification. Selection between the two Panasonic options depends on required tolerance: ±0.1% for ERA-6AEB1271V or ±0.5% for ERA-6AED1271V.
