Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE07681KL are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 681 kOhms
• Package / Case: 1206 (3216 Metric)
• Power rating: 0.25W (1/4W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better
• Physical dimensions: Minor variations within 1206 package specification
• Moisture sensitivity level: 1 (Unlimited) or equivalent

Three substitute parts meet these criteria: RT1206BRD07681KL (YAGEO), ERA-8AEB6813V (Panasonic), and RP73D2B681KBTDF (TE Connectivity).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07681KL (YAGEO): Direct manufacturer upgrade within the same RT series. Offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package and power specifications. Suitable for applications requiring tighter tolerance performance without changing supplier or assembly process.

ERA-8AEB6813V (Panasonic): Qualified to AEC-Q200 automotive standard with equivalent electrical performance to RT1206BRD07681KL. Temperature coefficient of ±25ppm/°C and ±0.1% tolerance. Appropriate for automotive-grade applications or designs requiring automotive-qualified components. Physical dimensions vary slightly (0.126" L x 0.063" W vs 0.122" L x 0.063" W) within 1206 package tolerance.

RP73D2B681KBTDF (TE Connectivity): Offers superior temperature coefficient performance (±15ppm/°C) with ±0.1% tolerance. Holsworthy series thin film construction. Suitable for precision applications requiring minimal temperature drift. Physical dimensions (0.120" L x 0.061" W) remain within 1206 package specification.

All three substitutes maintain active product status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07681KL replace RT1206FRE07681KL in any application?

A: Yes, within the constraints of tolerance requirements. RT1206BRD07681KL provides tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it suitable for applications currently using RT1206FRE07681KL. The reverse substitution (RT1206FRE07681KL for RT1206BRD07681KL) is not recommended where ±0.1% tolerance is specified.

Q: What is the difference between ERA-8AEB6813V and the YAGEO alternatives?

A: ERA-8AEB6813V is AEC-Q200 automotive qualified, whereas RT1206FRE07681KL and RT1206BRD07681KL are industrial-grade components. Electrical performance (resistance, tolerance, temperature coefficient) is equivalent to RT1206BRD07681KL. Use ERA-8AEB6813V only when automotive qualification is required.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within 1206 package specification. RT1206FRE07681KL and RT1206BRD07681KL measure 0.122" L x 0.063" W. ERA-8AEB6813V measures 0.126" L x 0.063" W. RP73D2B681KBTDF measures 0.120" L x 0.061" W. All remain within 1206 (3216 Metric) package tolerance and are PCB footprint compatible.

Q: Which substitute offers the best temperature stability?

A: RP73D2B681KBTDF provides the lowest temperature coefficient at ±15ppm/°C, compared to ±25ppm/°C for ERA-8AEB6813V and RT1206BRD07681KL, and ±50ppm/°C for the main part RT1206FRE07681KL. Select RP73D2B681KBTDF for applications requiring minimal temperature-induced resistance drift.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. RT1206BRD07681KL, ERA-8AEB6813V, and RP73D2B681KBTDF are all supplied in Tape & Reel (TR) packaging, matching the main part specification for automated assembly compatibility.
