RT0805FRE077K87L Equivalent & Substitute Parts

Part Overview

The RT0805FRE077K87L is a 7.87 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This component is rated for 0.125W (1/8W) 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 level (MSL 1). Equivalent and substitute parts are identified based on matching resistance value, package form factor, and electrical performance within acceptable tolerance and power rating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE077K87L are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 7.87 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1% (±0.1% or ±0.5% acceptable)
• Power rating: May be equal to or greater than 0.125W (0.25W acceptable)
• Temperature coefficient: May differ within thin film specifications
• Height and dimensional tolerances: Within supplier device package 0805 specification

Four substitute parts meet these criteria across three manufacturers: TE Connectivity Passive Product, Panasonic Electronic Components, and Susumu.

Parameter Comparison

Engineering Selection Recommendations

Standard Industrial Applications: The 9-2176092-5 (TE Connectivity) provides direct substitution with improved tolerance (±0.1%) and increased power rating (0.25W). This part is suitable for applications where enhanced performance margin is acceptable and space constraints permit the maximum height of 0.026" (0.65mm).

Automotive and High-Reliability Applications: ERA-6AEB7871V (Panasonic) and RG2012P-7871-B-T5 (Susumu) both carry AEC-Q200 automotive qualification. ERA-6AEB7871V maintains the original 0.125W power rating and 0.024" height. RG2012P-7871-B-T5 offers the same electrical specifications with reduced height (0.020") and anti-sulfur protection. Both feature ±25ppm/°C temperature coefficient, superior to the original ±50ppm/°C specification.

Cost-Optimized Selection with Relaxed Tolerance: RG2012P-7871-D-T5 (Susumu) provides AEC-Q200 qualification with ±0.5% tolerance and anti-sulfur protection. This part is appropriate where tolerance relaxation from ±1% to ±0.5% is acceptable and automotive-grade reliability is required.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range. Selection should be based on application requirements for automotive qualification, tolerance precision, power dissipation margin, and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can the 9-2176092-5 replace the RT0805FRE077K87L in any application?

A: The 9-2176092-5 is electrically compatible as a direct substitute. The primary consideration is physical height: the TE Connectivity part measures 0.026" (0.65mm) maximum seated height compared to 0.024" (0.60mm) for the original. Verify PCB clearance and component stacking requirements before substitution.

Q: What is the advantage of ERA-6AEB7871V and RG2012P-7871-B-T5 over the original part?

A: Both parts carry AEC-Q200 automotive qualification and feature ±25ppm/°C temperature coefficient versus ±50ppm/°C for the original. This provides superior temperature stability. Both maintain the original 0.125W power rating and 0.024" height (RG2012P-7871-B-T5 is 0.020"). RG2012P-7871-B-T5 adds anti-sulfur protection for harsh environments.

Q: Is tolerance tightening from ±1% to ±0.1% always beneficial?

A: Tighter tolerance (±0.1%) reduces circuit variation and improves performance predictability. However, substitution is only necessary if the application circuit design requires this precision. For general-purpose applications, the original ±1% tolerance is typically sufficient.

Q: Can RG2012P-7871-D-T5 be used where ±1% tolerance is specified?

A: RG2012P-7871-D-T5 has ±0.5% tolerance, which is tighter than the ±1% specification. This part is compatible and provides improved tolerance performance. The relaxation from ±1% to ±0.5% does not compromise circuit function.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, matching the original RT0805FRE077K87L packaging format for automated assembly compatibility.

Q: What is the significance of anti-sulfur protection in RG2012P-7871-B-T5 and RG2012P-7871-D-T5?

A: Anti-sulfur protection prevents corrosion of component terminations in environments with hydrogen sulfide exposure or high-sulfur industrial atmospheres. This feature is not present in the original part or other substitutes. Specify these Susumu parts only if anti-sulfur protection is required by application environment.
