Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F1370CS is based on the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value must be 137 Ohms
• Tolerance must be ±1% or tighter
• Temperature coefficient must be ±100ppm/°C or superior
• Operating temperature range must encompass -55°C to 155°C

Mechanical Compatibility Requirements:

• Package format must be 2010 (5025 Metric)
• Physical dimensions must be 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Composition must be thick film
• Number of terminations must be 2

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating must be 1 (Unlimited) or equivalent
• REACH Unaffected status required

The substitute part RMCF2010FT137R meets all electrical and mechanical compatibility criteria while providing equal or superior power rating (0.75W vs. 0.667W) and includes automotive-grade AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1370CS (Samsung Electro-Mechanics) is the primary component specification. Selection of this part is appropriate for applications requiring Samsung-sourced components or when bulk packaging is preferred.

RMCF2010FT137R (Stackpole Electronics Inc) is a direct electrical and mechanical substitute with the following considerations:

1. Power Rating Advantage: The Stackpole part is rated at 0.75W, exceeding the Samsung specification of 0.667W. This provides additional thermal margin in power dissipation applications.

2. Automotive Certification: The RMCF2010FT137R carries AEC-Q200 automotive-grade qualification. This certification is applicable to applications requiring automotive-level reliability and quality assurance, though it does not restrict use in non-automotive applications.

3. Physical Dimensions: Maximum seated height differs by 0.002" (0.04mm), with the Stackpole part at 0.028" versus Samsung at 0.026". This minimal difference is within typical PCB design tolerances for 2010 package components.

4. Packaging Format: The Stackpole part is supplied in Tape & Reel format, which is standard for high-volume automated assembly. The Samsung part may be available in alternative packaging formats.

5. Regulatory Compliance: Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 1 ratings, ensuring equivalent environmental and regulatory standing.

Selection between these parts should be based on supply availability, preferred supplier relationships, and packaging requirements rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT137R replace RC5025F1370CS in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (137 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and package format (2010/5025 Metric). The Stackpole part's higher power rating (0.75W vs. 0.667W) provides additional thermal capability. The 0.002" height difference is within standard PCB design tolerances.

Q: What is the significance of AEC-Q200 certification on the Stackpole part?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability and quality for automotive applications. This certification does not restrict the part's use in non-automotive applications. It indicates that the Stackpole part has undergone additional qualification testing and quality assurance processes.

Q: Are there any compatibility issues with the different packaging formats?

A: No compatibility issues exist regarding electrical or mechanical performance. The difference is in supply format: Tape & Reel (TR) packaging is optimized for automated assembly lines, while alternative formats may be used for manual assembly or lower-volume applications. PCB footprint and soldering characteristics remain identical.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both RC5025F1370CS and RMCF2010FT137R are rated MSL 1 (Unlimited), indicating unlimited shelf life under normal storage conditions without moisture baking requirements prior to soldering.

Q: Is the 0.002" height difference between parts significant?

A: No. The height difference (0.026" vs. 0.028") is 0.002" or 0.04mm, which is negligible for standard PCB design. This falls well within typical component placement tolerances and does not affect circuit performance or board assembly.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts meet RoHS3 compliance and REACH requirements. The Stackpole part includes AEC-Q200 automotive certification, which may be preferred for high-reliability applications. Verify specific application requirements and qualification standards before final selection.

Q: What is the temperature coefficient specification and why does it matter?

A: Both parts have a temperature coefficient of ±100ppm/°C, meaning resistance changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification is identical between parts and ensures predictable resistance stability across the -55°C to 155°C operating range.
