RT0805FRE071K91L Equivalent & Substitute Parts

Part Overview

The RT0805FRE071K91L is a 1.91 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO and classified as Active product status, this component is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). The part operates across -55°C to 155°C temperature range with a temperature coefficient of ±50ppm/°C. Equivalent and substitute parts are identified based on matching resistance value, package form factor, and electrical performance within specified tolerance and power rating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE071K91L is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 1.91 kOhms (exact match required)
• Package form factor: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 Compliant

Tolerance Consideration: The main part specifies ±1% tolerance. Substitute parts with ±0.1% tolerance meet this requirement as tighter tolerance is a functional upgrade. Parts with looser tolerance do not qualify.

Power Rating Consideration: The main part is rated at 0.125W (1/8W). Substitute parts rated at 0.125W or higher power dissipation are acceptable. The 4-2176092-2 rated at 0.25W (1/4W) exceeds the minimum requirement.

Temperature Coefficient: Substitute parts with ±25ppm/°C temperature coefficient meet the requirement as this represents improved stability compared to the main part's ±50ppm/°C specification.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance consistent with the main part specification.

RT0805BRD071K91L (YAGEO): Direct upgrade from the same manufacturer with improved tolerance (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C). Identical power rating and package specifications. Suitable for applications requiring enhanced precision without additional environmental qualifications.

4-2176092-2 (TE Connectivity Passive Product): Meets all electrical parameters with increased power rating (0.25W vs 0.125W), providing thermal margin in power-dissipation-sensitive applications. Identical tolerance and temperature coefficient to RT0805BRD071K91L. Height specification differs slightly (0.026" vs 0.024" maximum seated height).

ERA-6AEB1911V (Panasonic Electronic Components): Qualified to Automotive AEC-Q200 standard with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for automotive and high-reliability applications requiring formal qualification documentation.

RG2012P-1911-B-T5 (Susumu): Qualified to Automotive AEC-Q200 standard with anti-sulfur feature. Meets all electrical parameters with lowest maximum seated height (0.020" vs 0.024"). Appropriate for automotive applications in corrosive environments or space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD071K91L replace RT0805FRE071K91L in any application?

A: Yes. RT0805BRD071K91L provides equivalent or superior electrical performance across all specified parameters. The tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) represent functional improvements. Both parts share identical package form factor, power rating, and operating temperature range.

Q: What is the primary difference between 4-2176092-2 and the other substitutes?

A: The 4-2176092-2 is rated at 0.25W (1/4W) power dissipation compared to 0.125W (1/8W) for other substitutes. This higher power rating provides additional thermal capacity. The maximum seated height is also slightly increased (0.026" vs 0.024"). All other electrical parameters remain equivalent.

Q: Are ERA-6AEB1911V and RG2012P-1911-B-T5 suitable for non-automotive applications?

A: Yes. Both parts meet all electrical specifications required for the main part and are ROHS3 compliant. Automotive AEC-Q200 qualification represents additional quality assurance and reliability documentation. These parts are functionally compatible in general industrial and consumer applications.

Q: What is the significance of the anti-sulfur feature in RG2012P-1911-B-T5?

A: The anti-sulfur feature addresses corrosion resistance in environments with hydrogen sulfide exposure or high-sulfur atmospheric conditions. For standard indoor or controlled environments, this feature provides no functional advantage. Selection should be based on specific environmental requirements.

Q: Do all substitute parts maintain the same physical dimensions?

A: All parts share the 0805 (2012 Metric) package designation with identical length (0.079") and width (0.049"). Maximum seated height varies slightly: RT0805FRE071K91L and ERA-6AEB1911V at 0.024", 4-2176092-2 at 0.026", and RG2012P-1911-B-T5 at 0.020". These variations are within standard PCB assembly tolerances for 0805 components.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts are qualified for Tape & Reel (TR) packaging and share identical supplier device package designation (0805). PCB footprints, solder reflow profiles, and assembly processes remain unchanged. Component placement and orientation are identical.
