Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF6193U is determined by strict equivalence across the following critical parameters:

• Resistance value: 619 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 qualified substitutes meet all substitution criteria: ERJ-1TNF6193U (Panasonic Electronic Components) and RMCF2512FT619K (Stackpole Electronics Inc).

Parameter Comparison

Engineering Selection Recommendations

For new designs, ERJ-S1TF6193U is the primary selection as it maintains active production status and includes anti-sulfur coating for enhanced environmental protection in automotive applications.

ERJ-1TNF6193U is electrically and mechanically equivalent but carries "Not For New Designs" status, indicating it is in legacy phase. This part is suitable only for replacement in existing designs or when supply constraints require substitution in established production lines.

RMCF2512FT619K from Stackpole Electronics Inc is an active production alternative that meets all electrical and mechanical specifications. This part is suitable for new designs and provides cross-manufacturer sourcing flexibility while maintaining full AEC-Q200 automotive qualification and ROHS3 compliance.

All three parts are functionally interchangeable within the specified electrical and mechanical parameters. Selection between active production parts (ERJ-S1TF6193U and RMCF2512FT619K) depends on supply availability, lead time, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6193U be used as a direct replacement for ERJ-S1TF6193U in new designs?

A: ERJ-1TNF6193U meets all electrical and mechanical specifications for direct substitution. However, it carries "Not For New Designs" status, indicating Panasonic has transitioned this part to legacy phase. For new designs, ERJ-S1TF6193U or RMCF2512FT619K are recommended.

Q: Are there any physical dimension differences between the substitute parts?

A: ERJ-S1TF6193U and ERJ-1TNF6193U have identical dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm). RMCF2512FT619K has a slightly shorter length of 0.248" L x 0.126" W (6.30mm x 3.20mm). Both dimensions are within the 2512 package specification and are mechanically compatible on standard PCB layouts.

Q: Do all substitute parts have the same anti-sulfur protection?

A: ERJ-S1TF6193U explicitly includes anti-sulfur coating. ERJ-1TNF6193U and RMCF2512FT619K do not list anti-sulfur as a feature. If anti-sulfur protection is a design requirement, ERJ-S1TF6193U is the only qualified option.

Q: Are all parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operating temperature, meeting automotive reliability standards.

Q: What is the difference in availability between these parts?

A: ERJ-S1TF6193U has 901 units in stock. ERJ-1TNF6193U has 4200 units in stock. RMCF2512FT619K has 5736 units in stock. Availability may vary by distributor and time period.
