Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F513CS is determined by strict adherence to the following parameters:

Critical Match Requirements (Non-Negotiable):

• Resistance value: 51 kOhms
• Tolerance: ±1% (or tighter)
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C (minimum)
• Moisture Resistance: Required
• RoHS3 Compliance: Required
• MSL Rating: Level 1 or better

Allowable Variation:

• Power Rating: Substitute parts may have equal or higher power dissipation ratings (0.667W or greater)

The RC2010FK-0751KL from YAGEO qualifies as a substitute because it maintains all critical electrical parameters while providing an upgraded power rating of 0.75W (3/4W), offering improved thermal margin in the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-0751KL from YAGEO is a qualified substitute for the RC5025F513CS from Samsung Electro-Mechanics based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical resistance value (51 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). These parameters ensure equivalent circuit performance and signal integrity.

Mechanical Compatibility: Both parts utilize the 2010 (5025 Metric) package with identical footprint dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) and negligible height variation (0.66mm vs. 0.65mm). Direct PCB substitution is possible without layout modification.

Regulatory Compliance: Both components are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. No compliance barriers exist for substitution.

Power Rating Enhancement: The RC2010FK-0751KL provides 0.75W (3/4W) power dissipation compared to the original 0.667W (2/3W) rating. This represents a 12.4% increase in thermal capacity, providing improved reliability margin in power-dissipation-critical applications without any electrical or mechanical compromise.

Product Status: Both components maintain Active product status, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0751KL be used as a direct replacement for RC5025F513CS?

A: Yes. Both components share identical electrical specifications (51 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C), identical package geometry (2010 / 5025 Metric), and equivalent regulatory compliance (RoHS3, REACH unaffected, MSL Level 1). The substitute offers higher power rating (0.75W vs. 0.667W) with no electrical or mechanical drawbacks.

Q: What is the significance of the higher power rating on the substitute part?

A: The RC2010FK-0751KL's 0.75W rating provides additional thermal headroom compared to the original 0.667W specification. In applications where the resistor dissipates power near its rated limit, the substitute reduces junction temperature stress and extends component lifetime. This is a beneficial characteristic that does not compromise circuit function.

Q: Are there any PCB layout considerations when substituting RC2010FK-0751KL for RC5025F513CS?

A: No layout modification is required. Both components use identical 2010 (5025 Metric) package dimensions and footprints. Height variation is negligible (0.66mm vs. 0.65mm), presenting no clearance or assembly concerns.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both RC5025F513CS and RC2010FK-0751KL are RoHS3 compliant, REACH unaffected, and rated MSL Level 1 (Unlimited moisture sensitivity). Both feature moisture-resistant thick film construction suitable for demanding environmental conditions.

Q: What is the temperature coefficient significance in substitution?

A: Both components maintain ±100ppm/°C temperature coefficient across the identical -55°C ~ 155°C operating range. This ensures equivalent resistance stability over temperature variations, critical for precision analog circuits and temperature-compensated applications.

Q: Can the substitute be used in applications where the original part is specified?

A: Yes, provided the application does not explicitly require the lower power rating of the original part. The substitute's higher power rating and identical electrical characteristics make it suitable for all applications designed for the RC5025F513CS.
