Substitute Part Grouping Explanation

Substitute parts for RT1206FRE079K09L are categorized based on the following allowed parameters:

Tolerance Enhancement Substitutes: Parts with improved tolerance (±0.1% vs ±1%) while maintaining identical resistance value, package format, power rating, and operating temperature range.

Automotive-Grade Substitutes: Parts meeting AEC-Q200 automotive qualification standards with enhanced tolerance and temperature coefficient specifications, same package and resistance value.

Power Rating Upgrade Substitutes: Parts with increased power dissipation capability (0.5W vs 0.25W) while maintaining resistance value, package format, and tolerance specifications.

All substitutes maintain the 1206 (3216 Metric) package format, 9.09 kOhms resistance value, 2 terminations, RoHS3 compliance, and MSL Level 1 rating. Operating temperature range remains -55°C ~ 155°C across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD079K09L (YAGEO): Direct upgrade within the same manufacturer series. Provides improved tolerance specification (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package format. Suitable for applications requiring tighter resistance tolerances without power or thermal constraints.

ERA-8AEB9091V (Panasonic): Automotive-grade alternative with AEC-Q200 certification. Matches tolerance and temperature coefficient improvements of RT1206BRD079K09L while adding automotive qualification. Appropriate for automotive and harsh-environment applications where component reliability standards are mandated.

RNCP1206FTD9K09 (Stackpole): Power-rated upgrade option with 0.5W capability versus 0.25W of the original part. Maintains ±1% tolerance matching the original specification. Anti-sulfur composition provides enhanced environmental resistance. Suitable for applications requiring increased power dissipation margin or corrosive environment protection.

All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and -55°C ~ 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD079K09L be used as a direct replacement for RT1206FRE079K09L?

A: Yes. Both parts share identical resistance value (9.09 kOhms), power rating (0.25W), package format (1206), and operating temperature range (-55°C ~ 155°C). RT1206BRD079K09L provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a compatible upgrade.

Q: What is the difference between ERA-8AEB9091V and RT1206BRD079K09L?

A: Both parts have identical electrical specifications (9.09 kOhms, ±0.1% tolerance, 0.25W, ±25ppm/°C). The primary difference is manufacturer and automotive certification. ERA-8AEB9091V carries AEC-Q200 automotive qualification and is manufactured by Panasonic. Physical dimensions vary slightly (3.20mm x 1.60mm vs 3.10mm x 1.60mm length).

Q: When should RNCP1206FTD9K09 be selected?

A: Select RNCP1206FTD9K09 when circuit design requires higher power dissipation capability (0.5W vs 0.25W) or when anti-sulfur composition is needed for corrosive environments. This part maintains ±1% tolerance matching the original specification but has a higher temperature coefficient (±100ppm/°C).

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

A: All substitute parts use 1206 (3216 Metric) package format with 2 terminations. Physical dimensions vary slightly between manufacturers but remain within 1206 package classification. Verify PCB footprint compatibility for ERA-8AEB9091V (3.20mm length vs 3.10mm standard).

Q: Do all parts meet RoHS3 compliance?

A: Yes. RT1206FRE079K09L, RT1206BRD079K09L, ERA-8AEB9091V, and RNCP1206FTD9K09 are all RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.
