Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF6981U is determined by strict equivalence across the following parameters:

• Resistance value: 6.98 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
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RMCF2512FT6K98 from Stackpole Electronics Inc meets all electrical and mechanical substitution criteria. Dimensional variations within manufacturing tolerances do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF6981U and RMCF2512FT6K98 are active production components with full AEC-Q200 automotive qualification. Selection between these parts may be based on:

• Packaging format: ERJ-S1TF6981U is supplied in Tape & Reel (TR) format; RMCF2512FT6K98 is supplied in Cut Tape (CT) format
• Inventory availability: RMCF2512FT6K98 has higher stock levels (16558 units vs. 1139 units)
• Dimensional tolerance: Both meet 2512 package specifications with minor length variations (6.40mm vs. 6.30mm) within standard manufacturing tolerances

Both parts maintain identical electrical performance, temperature stability, and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can RMCF2512FT6K98 be used as a direct replacement for ERJ-S1TF6981U?

A: Yes. Both parts share identical electrical specifications (6.98 kOhms ±1%, 1W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), package type (2512), and automotive compliance (AEC-Q200). Functional equivalence is maintained.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is used for automated assembly processes with continuous component feeding. Cut Tape (CT) packaging provides individual component strips for manual or semi-automated assembly. Both formats contain identical components; packaging selection depends on assembly equipment and production volume.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard manufacturing tolerances. ERJ-S1TF6981U length is 6.40mm; RMCF2512FT6K98 length is 6.30mm. Both conform to 2512 package specifications and are mechanically compatible with standard PCB footprints.

Q: Do both parts meet automotive standards?

A: Yes. Both ERJ-S1TF6981U and RMCF2512FT6K98 carry AEC-Q200 qualification, confirming suitability for automotive applications across the specified operating temperature range.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without moisture bake-out requirements. Both parts can be stored and handled under standard conditions without special moisture control procedures.
