Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF3302U is determined by strict alignment of the following parameters:

• Resistance value: 33 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Termination count: 2

All identified substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (height-seated) and specific feature sets (anti-sulfur vs. moisture resistant) do not affect functional interchangeability within the defined parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and MSL 1 rating. Selection between ERJ-S1DF3302U, RC2010FK-0733KL, and RMCF2010FT33K0 depends on application-specific requirements:

The ERJ-S1DF3302U and RMCF2010FT33K0 both carry AEC-Q200 automotive qualification, making them suitable for automotive applications requiring formal qualification compliance. The RC2010FK-0733KL features moisture-resistant properties without automotive qualification.

Physical height variation (0.70mm for Panasonic and Stackpole vs. 0.65mm for YAGEO) may be relevant for applications with strict PCB clearance constraints, though all parts maintain identical length and width dimensions.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0733KL replace ERJ-S1DF3302U in automotive applications?

A: RC2010FK-0733KL meets all core electrical and mechanical specifications. However, it lacks AEC-Q200 automotive qualification. Use only if automotive qualification is not a design requirement.

Q: Are there differences in reliability between these three parts?

A: All three parts are active products with identical electrical specifications, temperature coefficients, and operating ranges. Reliability differences, if any, depend on manufacturer-specific quality processes and are not reflected in the provided specifications.

Q: Does the height difference between parts affect PCB assembly?

A: The maximum seated height varies: ERJ-S1DF3302U and RMCF2010FT33K0 are 0.70mm, while RC2010FK-0733KL is 0.65mm. Verify PCB clearance requirements before substitution if height-sensitive applications are involved.

Q: Are all parts available in Tape & Reel packaging?

A: Yes, all three parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection (ERJ-S1DF3302U, RMCF2010FT33K0) addresses corrosion from sulfur-containing environments. Moisture-resistant properties (RC2010FK-0733KL) address humidity exposure. Both are thick film resistor enhancements; selection depends on environmental exposure conditions.
