Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE0754K9L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 54.9 kOhms
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric)
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thin Film

Allowable Variations:

• Tolerance: Equal to or tighter than ±1%
• Temperature coefficient: Equal to or better than ±50ppm/°C
• Certifications and features: May exceed base specifications

Two substitute parts meet these criteria: RT1206BRE0754K9L (YAGEO, tighter tolerance upgrade) and ERA-8AEB5492V (Panasonic, automotive-grade with AEC-Q200 certification).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRE0754K9L (YAGEO): Direct upgrade within the same manufacturer series. Maintains identical package, power rating, and temperature range while providing tighter tolerance (±0.1% vs ±1%). Suitable for applications requiring improved resistance accuracy without automotive certification requirements. Active product status with equivalent inventory availability.

ERA-8AEB5492V (Panasonic): Automotive-grade alternative with AEC-Q200 certification and superior temperature coefficient (±25ppm/°C vs ±50ppm/°C). Meets all electrical and mechanical compatibility requirements. Recommended for automotive applications, harsh environments, or systems requiring enhanced reliability documentation. Slight dimensional variation (3.20mm L vs 3.10mm L; 0.70mm H vs 0.65mm H) remains within standard 1206 package tolerance.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRE0754K9L be used as a direct replacement for RT1206FRE0754K9L?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, and operating temperature range. The substitute offers improved tolerance specification (±0.1% vs ±1%), making it functionally compatible and electrically superior for the same circuit application.

Q: What is the primary difference between the two substitute parts?

A: RT1206BRE0754K9L is a standard industrial-grade upgrade from YAGEO. ERA-8AEB5492V is an automotive-grade component from Panasonic with AEC-Q200 certification and lower temperature coefficient (±25ppm/°C). Select ERA-8AEB5492V for automotive or mission-critical applications requiring enhanced reliability documentation.

Q: Are there package compatibility concerns with ERA-8AEB5492V?

A: ERA-8AEB5492V maintains 1206 (3216 Metric) package classification. Dimensional variations (length 3.20mm vs 3.10mm; height 0.70mm vs 0.65mm) fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or soldering procedures.

Q: Which substitute should be selected for cost optimization?

A: RT1206BRE0754K9L provides the most direct cost-effective upgrade path, offering tighter tolerance within the same YAGEO product line. ERA-8AEB5492V carries higher cost due to automotive certification but is justified only when AEC-Q200 compliance is a system requirement.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE0754K9L, RT1206BRE0754K9L, and ERA-8AEB5492V are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), suitable for standard manufacturing and storage conditions.
