Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE074K22L are qualified based on the following criteria:

• Identical Resistance Value: 4.22 kOhms
• Identical Package Format: 1206 (3216 Metric)
• Identical Power Rating: 0.25W (1/4W)
• Identical Composition: Thin Film
• Identical Operating Temperature Range: -55°C ~ 155°C
• Equal or Superior Tolerance: ±1% or better
• Compliance Equivalence: RoHS3 and REACH status maintained

Substitutes are grouped into two categories: direct tolerance upgrades (±0.1%) and automotive-qualified variants. All substitutes maintain mechanical and thermal compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD074K22L (YAGEO): This substitute offers improved tolerance performance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical mechanical compatibility and package format. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB4221V (Panasonic Electronic Components): This substitute provides equivalent tolerance and temperature coefficient performance to the RT1206BRD074K22L while adding AEC-Q200 automotive qualification. Selection is appropriate for automotive applications, harsh environment deployments, or systems requiring automotive-grade component reliability. Physical dimensions show minor variation (0.126" L x 0.063" W versus 0.122" L x 0.063" W) and maximum seated height (0.028" versus 0.026"), which must be verified for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD074K22L be used as a direct replacement for RT1206FRE074K22L?

A: Yes. Both components share identical resistance value, package format, power rating, and operating temperature range. The RT1206BRD074K22L provides superior tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it a direct upgrade with no circuit redesign required.

Q: What is the primary difference between RT1206BRD074K22L and ERA-8AEB4221V?

A: Both offer identical electrical specifications (4.22 kOhms ±0.1%, 0.25W, -55°C ~ 155°C). The ERA-8AEB4221V includes AEC-Q200 automotive qualification and has slightly larger physical dimensions (0.126" L x 0.028" H maximum versus 0.122" L x 0.026" H maximum). Selection depends on automotive requirement and PCB layout constraints.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and REACH unaffected status, matching the original RT1206FRE074K22L specification.

Q: Can ERA-8AEB4221V be used in non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of standard reliability requirements. The ERA-8AEB4221V can be used in any application where the original part is specified, provided physical dimensions are compatible with PCB layout.

Q: What packaging formats are available for these substitutes?

A: All listed parts are supplied in Tape & Reel (TR) packaging format, consistent with the original RT1206FRE074K22L specification.
