Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2701U is determined by strict alignment of the following parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RC2512FK-072K7L from YAGEO meets all these electrical and mechanical criteria, qualifying it as a direct substitute. Both parts share identical resistance, tolerance, power rating, package dimensions, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF2701U and RC2512FK-072K7L are active production components with ROHS3 compliance and identical electrical specifications. The ERJ-S1TF2701U carries automotive AEC-Q200 qualification and anti-sulfur properties, while the RC2512FK-072K7L features moisture-resistant construction. Selection between these parts should be based on specific application requirements: choose the ERJ-S1TF2701U for automotive applications requiring AEC-Q200 certification, or the RC2512FK-072K7L when moisture resistance is the primary design consideration. Both parts are suitable for the -55°C to 155°C operating range and meet unlimited moisture sensitivity level specifications.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-072K7L replace ERJ-S1TF2701U in automotive applications?

A: Both parts share identical electrical specifications and package dimensions. However, the ERJ-S1TF2701U carries AEC-Q200 automotive qualification. If AEC-Q200 certification is a design requirement, the ERJ-S1TF2701U is the specified choice. For non-AEC-Q200 applications, RC2512FK-072K7L is electrically compatible.

Q: Are there physical compatibility concerns between these parts?

A: Physical dimensions differ slightly. The ERJ-S1TF2701U measures 0.252" L x 0.126" W (6.40mm x 3.20mm) with 0.028" maximum seated height, while the RC2512FK-072K7L measures 0.250" L x 0.122" W (6.35mm x 3.10mm) with 0.026" maximum seated height. Both fit the 2512 package footprint and are mechanically compatible in standard PCB layouts.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection prevents degradation from sulfur-containing environments, while moisture-resistant construction protects against humidity ingress. These are distinct protective mechanisms addressing different environmental stressors. Application environment determines which feature is necessary.

Q: Are both parts available in tape and reel packaging?

A: Yes, both ERJ-S1TF2701U and RC2512FK-072K7L are supplied in tape and reel (TR) packaging suitable for automated assembly processes.

Q: Do these parts meet REACH compliance?

A: Both parts have REACH Unaffected status, indicating they are not subject to REACH substance restrictions.
