Equivalent & Substitute Parts for ERJ-S1TF6191U

Part Overview

The ERJ-S1TF6191U is a 6.19 kOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 1128 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits equivalent alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF6191U is determined by strict equivalence across the following parameters:

• Resistance value: 6.19 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Two substitute parts meet all substitution criteria: ERJ-1TNF6191U (Panasonic Electronic Components) and CRCW25126K19FKEG (Vishay Dale). Both parts are electrically and mechanically equivalent to the primary part across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

ERJ-S1TF6191U remains the primary selection for new designs due to its active product status and anti-sulfur feature set. This part is recommended for applications requiring long-term supply continuity and design stability.

ERJ-1TNF6191U is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part is suitable only for legacy system maintenance, repair, or replacement scenarios where the original specification must be maintained. New design implementations should not incorporate this part.

CRCW25126K19FKEG is an active, equivalent alternative from Vishay Dale. This part meets all electrical and mechanical requirements and maintains full AEC-Q200 automotive qualification. Selection of this part is appropriate when supply of the primary part is constrained or when multi-source component strategies are required. Dimensional tolerance differences (0.248" L x 0.124" W versus 0.252" L x 0.126" W) remain within acceptable PCB layout margins for 2512 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6191U be used as a direct replacement for ERJ-S1TF6191U?

A: ERJ-1TNF6191U is electrically and mechanically equivalent and will function identically in the circuit. However, this part carries "Not For New Designs" status. Use this part only for maintenance or repair of existing systems where the original specification must be preserved. New designs should not incorporate this part.

Q: What is the difference between ERJ-S1TF6191U and CRCW25126K19FKEG?

A: Both parts are electrically equivalent with identical resistance, tolerance, power rating, temperature coefficient, and operating range. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. The primary differences are manufacturer (Panasonic versus Vishay Dale) and minor dimensional variations within the 2512 package specification. CRCW25126K19FKEG is available in higher inventory quantities.

Q: Are there packaging differences between the substitute parts?

A: ERJ-S1TF6191U is supplied in Tape & Reel (TR) packaging. ERJ-1TNF6191U is also supplied in Tape & Reel (TR). CRCW25126K19FKEG is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format does not affect electrical performance or PCB assembly compatibility.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share identical 2512 (6432 Metric) package specifications and footprints. Dimensional variations between manufacturers (0.248" to 0.252" length, 0.124" to 0.126" width) fall within standard PCB design tolerances for this package class and do not require layout modifications.

Q: What certifications apply to all substitute parts?

A: All three parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 (Unlimited). All parts are suitable for automotive and industrial applications requiring these certifications.
