Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF1301U is determined by strict equivalence across the following parameters:

Resistance value and tolerance must match exactly at 1.3 kOhms ±1%. Power rating must be equivalent at 0.75W. Package designation must be identical at 2010 (5025 Metric) to ensure mechanical and electrical compatibility on printed circuit boards. Temperature coefficient must remain within ±100ppm/°C. Operating temperature range must span -55°C to 155°C minimum. Automotive AEC-Q200 qualification is required for applications demanding automotive-grade reliability. RoHS3 compliance and MSL 1 rating must be maintained. All substitute parts must be thick film composition resistors.

The AC2010FK-071K3L from YAGEO meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1DF1301U and AC2010FK-071K3L are active production parts with identical electrical specifications and AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements. The Panasonic ERJ-S1DF1301U features anti-sulfur properties, while the YAGEO AC2010FK-071K3L emphasizes moisture-resistant characteristics. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. The marginal difference in seated height (0.70mm versus 0.65mm) is within typical PCB assembly tolerances and does not affect functional compatibility. Part selection should be determined by inventory availability, lead time, and established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-071K3L replace ERJ-S1DF1301U in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, maintain identical electrical specifications (1.3 kOhms ±1%, 0.75W), and operate across the same temperature range (-55°C to 155°C). Package dimensions are equivalent at 2010 (5025 Metric).

Q: Are there differences in physical dimensions between these parts?

A: Both parts share identical length and width dimensions of 0.197" x 0.098" (5.00mm x 2.50mm). The seated height differs slightly: ERJ-S1DF1301U at 0.028" (0.70mm) and AC2010FK-071K3L at 0.026" (0.65mm). This variation is within standard PCB assembly tolerances.

Q: What is the significance of anti-sulfur versus moisture-resistant features?

A: Anti-sulfur properties in the ERJ-S1DF1301U protect against sulfur-containing atmospheric contaminants. Moisture-resistant characteristics in the AC2010FK-071K3L enhance performance in humid environments. Both parts maintain MSL 1 (Unlimited) rating, indicating robust moisture handling. Feature selection depends on specific environmental exposure conditions.

Q: Are both parts RoHS compliant?

A: Yes. Both ERJ-S1DF1301U and AC2010FK-071K3L are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

A: Yes. Identical package designation (2010), electrical specifications, and compliance ratings ensure direct interchangeability. The minimal height difference does not affect assembly or functionality.
