RT0805CRE075K49L Equivalent & Substitute Parts

Part Overview

The RT0805CRE075K49L is a 5.49 kOhms ±0.25% 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 with MSL 1 rating and is currently in active production status with 661 units in stock.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand improved tolerance specifications, when automotive-grade reliability is required, or when alternative manufacturers' inventory provides better availability.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE075K49L is determined by the following mandatory parameters:

Resistance value: 5.49 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 (exact match or better required)
RoHS compliance: ROHS3 Compliant (exact match required)
MSL rating: 1 or better (exact match or better required)

Tolerance and temperature coefficient may vary within acceptable engineering limits. Power rating may be equal or higher. Automotive certifications (AEC-Q200) and anti-sulfur features represent enhancements that do not prevent substitution.

Engineering Selection Recommendations

All listed substitute parts meet the mandatory substitution criteria for the RT0805CRE075K49L. Selection among equivalents should be based on the following factors:

RT0805BRD075K49L (YAGEO): Direct manufacturer upgrade with improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). Maintains identical power rating and package. Suitable for applications requiring tighter tolerance specifications while remaining within the same manufacturer ecosystem.

8-2176092-2 (TE Connectivity): Offers increased power rating (0.25W vs 0.125W) with improved tolerance and temperature coefficient. Appropriate for designs requiring higher power dissipation capability or when TE Connectivity supply chain is preferred.

ERA-6AEB5491V (Panasonic): Automotive-grade component with AEC-Q200 certification. Maintains original power rating with improved tolerance and temperature coefficient. Suitable for automotive applications or when automotive-grade reliability is specified.

RG2012P-5491-B-T5 (Susumu): Automotive-grade component with AEC-Q200 certification and anti-sulfur feature. Maintains original power rating with improved tolerance and temperature coefficient. Highest inventory availability. Suitable for automotive applications in corrosive environments or when anti-sulfur protection is required.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD075K49L replace RT0805CRE075K49L in any application?

A: Yes. RT0805BRD075K49L is a direct upgrade with identical package, resistance value, and power rating. The improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) make it suitable for all applications where the original part is used.

Q: What is the difference between the TE Connectivity 8-2176092-2 and other substitutes?

A: The 8-2176092-2 provides double the power rating (0.25W vs 0.125W) while maintaining the same 0805 package footprint. This allows for higher power dissipation in the same physical space. All other electrical parameters match the upgrade specifications.

Q: Are ERA-6AEB5491V and RG2012P-5491-B-T5 suitable for non-automotive applications?

A: Yes. Both parts exceed the requirements of the original RT0805CRE075K49L with improved tolerance and temperature coefficient. Automotive certification does not restrict use in non-automotive applications. The anti-sulfur feature of RG2012P-5491-B-T5 provides additional protection in corrosive environments regardless of application type.

Q: Do all substitute parts use the same PCB footprint?

A: Yes. All listed parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical board layout compatibility is guaranteed.

Q: Which substitute offers the best availability?

A: RG2012P-5491-B-T5 (Susumu) has the highest inventory with 59,277 units in stock, followed by ERA-6AEB5491V (Panasonic) with 7,898 units.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, matching the environmental and regulatory status of the original RT0805CRE075K49L.
