Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE071K43L are qualified based on the following criteria:

• Resistance Value: Exact match at 1.43 kOhms
• Package / Case: Identical 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Operating Temperature Range: Minimum -55°C ~ 155°C coverage
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity: MSL 1 (Unlimited)

Tolerance and power rating variations are permitted when the substitute part meets or exceeds the electrical performance requirements of the original specification. Temperature coefficient improvements are acceptable enhancements.

Engineering Selection Recommendations

RT0805BRD071K43L (YAGEO): Direct upgrade within the same manufacturer series. Improves tolerance to ±0.1% and reduces temperature coefficient to ±25ppm/°C while maintaining identical power rating and package specifications. Suitable for applications requiring enhanced precision without design modification.

ERA-6AEB1431V (Panasonic Electronic Components): Meets all electrical and mechanical requirements with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Includes Automotive AEC-Q200 qualification, applicable for automotive-grade applications. Identical package and thermal characteristics to the original part.

RP73PF2A1K43BTDF (TE Connectivity Passive Product): Provides increased power dissipation capability at 0.25W (1/4W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maximum seated height increases to 0.026" (0.65mm). Suitable for applications requiring higher power handling within the same footprint class.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active product status.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD071K43L replace RT0805FRE071K43L directly?

A: Yes. Both parts share identical resistance value, package, power rating, and operating temperature range. The substitute offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). No circuit redesign is required.

Q: What is the key difference between ERA-6AEB1431V and the original part?

A: ERA-6AEB1431V maintains all critical electrical specifications and package dimensions. The primary distinction is Automotive AEC-Q200 qualification, making it suitable for automotive applications. Tolerance and temperature coefficient are improved.

Q: Why does RP73PF2A1K43BTDF have a higher power rating?

A: RP73PF2A1K43BTDF is rated at 0.25W (1/4W) compared to the original 0.125W (1/8W). This provides additional thermal margin in applications with higher power dissipation. The 0805 package dimensions remain identical; seated height increases by 0.002" (0.05mm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RT0805FRE071K43L specifications.

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

A: Yes, within the stated package and height specifications. RP73PF2A1K43BTDF has a maximum seated height of 0.026" (0.65mm) versus 0.024" (0.60mm) for other parts. Verify clearance in space-constrained designs.
