Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE071K24L is determined by the following mandatory parameters:

• Resistance Value: Must be 1.24 kOhms
• Package / Case: Must be 0805 (2012 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: Must be ROHS3 compliant
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents (Same Tolerance & Power Rating)

• RT0805DRE071K24L: Identical specifications with improved tolerance (±0.5% vs ±1%)

Category 2 - Enhanced Performance Substitutes (Improved Tolerance and/or Power Rating)

• ERA-6AEB1241V: Superior tolerance (±0.1%), automotive-grade AEC-Q200 certification, lower temperature coefficient (±25ppm/°C)
• RP73PF2A1K24BTDF: Superior tolerance (±0.1%), increased power rating (0.25W vs 0.125W), lower temperature coefficient (±25ppm/°C)

Parameter Comparison

Engineering Selection Recommendations

RT0805DRE071K24L is the direct equivalent for applications requiring the same power rating. This YAGEO part maintains identical package and thermal specifications while offering improved tolerance (±0.5%), making it suitable for circuits where tighter resistance accuracy is beneficial without requiring automotive qualification.

ERA-6AEB1241V is recommended for applications requiring automotive-grade reliability. This Panasonic component carries AEC-Q200 certification and provides superior tolerance (±0.1%) with a lower temperature coefficient (±25ppm/°C). It is suitable for automotive, industrial, or high-reliability applications where environmental stress screening and extended temperature stability are required.

RP73PF2A1K24BTDF is recommended for applications with higher power dissipation requirements or where enhanced precision is critical. This TE Connectivity part doubles the power rating to 0.25W while maintaining the 0805 package footprint, and provides ±0.1% tolerance with ±25ppm/°C temperature coefficient. It is suitable for precision analog circuits or applications with elevated thermal stress.

All substitute parts maintain full compatibility with the original RT0805FRE071K24L in terms of package dimensions, mounting footprint, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE071K24L be used as a direct replacement for RT0805FRE071K24L?

A: Yes. Both parts share identical resistance value (1.24 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). The RT0805DRE071K24L offers improved tolerance (±0.5% vs ±1%) with no functional or mechanical incompatibility.

Q: What is the primary difference between ERA-6AEB1241V and the original part?

A: ERA-6AEB1241V provides three key enhancements: superior tolerance (±0.1% vs ±1%), automotive AEC-Q200 certification, and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). The power rating and package remain identical. This part is suitable for applications requiring automotive-grade reliability or precision analog circuits.

Q: When should RP73PF2A1K24BTDF be selected over other substitutes?

A: RP73PF2A1K24BTDF should be selected when the circuit requires higher power dissipation capability. This part provides double the power rating (0.25W vs 0.125W) while maintaining the same 0805 package footprint. It also offers ±0.1% tolerance and ±25ppm/°C temperature coefficient, making it ideal for precision applications with elevated thermal stress.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RT0805FRE071K24L format. All parts maintain identical physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and are compatible with standard SMD assembly equipment.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) rating, matching the environmental and regulatory compliance of the original RT0805FRE071K24L.

Q: Can ERA-6AEB1241V be used in non-automotive applications?

A: Yes. While ERA-6AEB1241V carries automotive AEC-Q200 certification, it can be used in any application requiring its electrical specifications. The automotive qualification indicates enhanced reliability and environmental stress screening, which benefits any high-reliability application.
