Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1TF1131U are qualified based on the following criteria:

• Identical resistance value: 1.13 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 1W
• Compatible package: 2512 (6432 Metric)
• Matching composition: Thick Film
• Identical temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Equivalent automotive certification: AEC-Q200
• Matching RoHS compliance: ROHS3 Compliant
• Equivalent moisture sensitivity: MSL 1 (Unlimited)

The RMCF2512FT1K13 from Stackpole Electronics Inc meets all these criteria and is therefore a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF1131U and RMCF2512FT1K13 are active production components with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts may be based on availability, lead time, or supply chain requirements. The Stackpole part (RMCF2512FT1K13) currently has higher inventory availability at 3836 units compared to 1094 units for the Panasonic part. Both components meet identical electrical and mechanical specifications for direct substitution in automotive and industrial applications operating within the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT1K13 be used as a direct replacement for ERJ-S1TF1131U?

A: Yes. Both parts share identical resistance (1.13 kOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive certification. They are electrically and mechanically interchangeable.

Q: Are there dimensional differences between these parts?
