Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF24R0U is determined by strict equivalence across the following parameters:

Resistance value and tolerance must match exactly at 24 Ohms ±1%. Power rating must be equivalent at 0.75W minimum. Package designation must be identical: 2010 (5025 Metric) surface mount format. Composition type must be thick film. Temperature coefficient must be ±100ppm/°C. Operating temperature range must span -55°C to 155°C minimum. Automotive qualification via AEC-Q200 certification is required. RoHS3 compliance and MSL 1 rating must be maintained.

The AC2010FK-0724RL from YAGEO meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1DF24R0U and AC2010FK-0724RL are active production components with full AEC-Q200 automotive qualification. Selection between these parts is based on availability and application-specific requirements. The Panasonic ERJ-S1DF24R0U features anti-sulfur construction, while the YAGEO AC2010FK-0724RL emphasizes moisture-resistant thick film technology. Both components maintain identical electrical performance and thermal characteristics. The marginal difference in seated height (0.70mm versus 0.65mm) is within typical PCB assembly tolerances for 2010 package components and does not affect functional compatibility in standard automotive circuit applications.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-0724RL replace ERJ-S1DF24R0U in automotive applications?

A: Yes. Both components meet AEC-Q200 qualification, maintain identical resistance, tolerance, power rating, and operating temperature specifications. The 2010 package dimensions are equivalent, and both are ROHS3 compliant with MSL 1 rating.

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

A: Both components use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). The seated height differs slightly: ERJ-S1DF24R0U at 0.028" (0.70mm) and AC2010FK-0724RL at 0.026" (0.65mm). This variation is within standard PCB assembly tolerances.

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

A: Anti-sulfur construction in the ERJ-S1DF24R0U protects against sulfur-containing environmental contaminants. Moisture-resistant construction in the AC2010FK-0724RL provides protection against humidity exposure. Both approaches are valid for automotive environments; selection depends on specific application exposure conditions.

Q: Do both parts require identical PCB footprints?

A: Yes. Both components use the 2010 (5025 Metric) package specification, requiring identical PCB land patterns and assembly procedures.

Q: Are there supply or availability considerations?

A: Current inventory shows 971 units of ERJ-S1DF24R0U and 3034 units of AC2010FK-0724RL available. Availability may vary based on procurement timing and supplier stock levels.
