Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2612U is determined by strict equivalence across the following critical parameters:

• Resistance value: 26.1 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these parameters without exception. Substitutes are sourced from qualified manufacturers including Panasonic Electronic Components and Vishay Dale, both established suppliers of automotive-grade passive components.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F2612U is the primary selection for new designs due to its active product status and current availability of 686 units in stock. This part carries anti-sulfur protection and meets all automotive qualification requirements.

The CRCW121026K1FKEA from Vishay Dale is a direct functional equivalent with active product status and higher inventory availability (15,986 units). The seated height is 0.024" compared to 0.028" for the Panasonic part, which may be relevant for applications with strict height constraints. Both parts are suitable for new designs.

The ERJ-14NF2612U from Panasonic is electrically and mechanically equivalent but carries a "Not For New Designs" status. This part should be used only in legacy design maintenance or when existing inventory must be consumed. It is available in higher quantity (14,957 units) and may be considered for non-critical applications or design revisions where product status restrictions do not apply.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2612U be used as a direct replacement for ERJ-S14F2612U?

A: Yes, the ERJ-14NF2612U is electrically and mechanically equivalent. Both parts share identical resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. However, the ERJ-14NF2612U carries a "Not For New Designs" status, making it suitable only for legacy applications or design revisions where this restriction does not apply.

Q: What is the difference between the Panasonic ERJ-S14F2612U and Vishay Dale CRCW121026K1FKEA?

A: Both parts are functionally equivalent across all critical electrical parameters. The primary difference is the seated height: the Vishay part measures 0.024" (0.60mm) maximum versus 0.028" (0.70mm) for the Panasonic part. For applications with strict PCB height requirements, the Vishay part offers a lower profile. Both are active products with AEC-Q200 automotive qualification.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C ~ 155°C). All are ROHS3 compliant and have MSL 1 moisture sensitivity ratings.

Q: Does the anti-sulfur feature of the ERJ-S14F2612U affect substitution compatibility?

A: The anti-sulfur feature is specific to the ERJ-S14F2612U and is not present in the ERJ-14NF2612U or CRCW121026K1FKEA. For applications where sulfur resistance is a design requirement, the ERJ-S14F2612U is the appropriate selection. For general automotive applications without specific sulfur exposure concerns, all three parts are functionally compatible.

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

A: Yes. All parts use the same 1210 (3225 Metric) package format with identical footprints and two terminations. The minor height difference in the Vishay part (0.024" vs 0.028") does not affect PCB assembly compatibility for standard applications.
