Equivalent & Substitute Parts for RT0805FRE0788K7L

Part Overview

The RT0805FRE0788K7L is an 88.7 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 a temperature coefficient of ±50ppm/°C and operates across -55°C to 155°C. The part is ROHS3 compliant, REACH unaffected, and carries MSL 1 (unlimited moisture sensitivity level). As an active product with established supply availability, substitute parts are identified for applications requiring enhanced tolerance specifications, increased power ratings, or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

Resistance value: 88.7 kOhms (exact match required)
Package: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Operating temperature range: -55°C to 155°C (minimum requirement)
RoHS compliance: ROHS3 (minimum requirement)

Allowable Variations:

Tolerance: May be equal to or tighter than ±1%
Power rating: May be equal to or greater than 0.125W
Temperature coefficient: May be equal to or lower in absolute value
Features: May include additional certifications (AEC-Q200, anti-sulfur)

Four substitute parts meet these criteria across three manufacturers, grouped by tolerance and power rating enhancements.

Engineering Selection Recommendations

RT0805BRD0788K7L (YAGEO): Direct upgrade within the same manufacturer series. Provides tighter tolerance (±0.1% vs ±1%) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package. Suitable for applications requiring enhanced precision without automotive certification requirements.

9-2176093-0 (TE Connectivity): Offers tighter tolerance and doubled power rating (0.25W vs 0.125W). Appropriate for designs with higher thermal dissipation margins or where increased power headroom is beneficial. Maintains standard industrial compliance.

ERA-6AEB8872V (Panasonic): Provides tighter tolerance and improved temperature coefficient with AEC-Q200 automotive qualification. Suitable for automotive applications or environments requiring automotive-grade component reliability.

RG2012P-8872-B-T5 (Susumu): Combines tighter tolerance, improved temperature coefficient, and dual certifications (AEC-Q200 and anti-sulfur protection). Appropriate for harsh automotive or corrosive environments where sulfur resistance is specified.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the required operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0788K7L replace RT0805FRE0788K7L in any application?

A: Yes. RT0805BRD0788K7L is a direct substitute with improved specifications (tighter tolerance and lower temperature coefficient). It is pin-compatible, uses identical packaging, and maintains the same power rating and operating temperature range.

Q: What is the primary difference between the TE Connectivity 9-2176093-0 and other substitutes?

A: The 9-2176093-0 provides doubled power rating (0.25W vs 0.125W). This is the only substitute with increased power dissipation capability. Select this part if thermal margin or higher power handling is required.

Q: Are ERA-6AEB8872V and RG2012P-8872-B-T5 interchangeable?

A: Both parts are electrically and mechanically compatible. The primary difference is that RG2012P-8872-B-T5 includes anti-sulfur protection in addition to AEC-Q200 certification. Select RG2012P-8872-B-T5 for environments with sulfur exposure risk.

Q: Can I use an automotive-grade substitute (ERA-6AEB8872V or RG2012P-8872-B-T5) in non-automotive applications?

A: Yes. Automotive-grade components meet or exceed industrial specifications and are fully compatible with non-automotive designs. No performance degradation occurs.

Q: Does tolerance improvement affect circuit performance?

A: Tighter tolerance (±0.1% vs ±1%) reduces resistance variation across the production batch, improving circuit consistency and predictability. This is beneficial for precision analog circuits, but may not be necessary for general-purpose applications.

Q: Are all substitutes available in the same packaging format?

A: Yes. All parts use 0805 (2012 Metric) package in Tape & Reel (TR) format, ensuring identical PCB footprint and automated assembly compatibility.
