RMCS2010FT1K50 Equivalent & Substitute Parts

Part Overview

The RMCS2010FT1K50 is a 1.5 kOhms ±1% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur construction and operates across -55°C to 155°C. The part is currently active in production with 1051 pieces in stock.

Substitute parts are necessary when the original RMCS2010FT1K50 becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications call for enhanced automotive qualification or moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts maintain electrical equivalence through identical resistance value (1.5 kOhms), tolerance (±1%), power rating (0.75W), and package format (2010 / 5025 Metric). Substitution is valid when the following parameters remain constant:

• Resistance: 1.5 kOhms
• Tolerance: ±1%
• Power (Watts): 0.75W
• Package / Case: 2010 (5025 Metric)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C
• Number of Terminations: 2
• Composition: Thick Film

Substitute parts are differentiated by manufacturer, packaging format (Tape & Reel vs. Cut Tape), feature enhancements (Automotive AEC-Q200, Moisture Resistant), and compliance certifications. Physical dimensions and height specifications remain within acceptable tolerances across all listed substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

RMCF2010FT1K50, AC2010FK-071K5L, CRCW20101K50FKEF, and RC2010FK-071K5L are all active production parts with ROHS3 compliance. These parts are suitable for new designs and ongoing production. Selection among these should be based on packaging format requirements (Tape & Reel vs. Cut Tape) and feature requirements (Automotive AEC-Q200 certification or Moisture Resistant construction).

Conditional Substitutes:

CRCW20101K50FKTF is active but carries RoHS non-compliance and REACH Affected status. This part is suitable only for applications where RoHS exemptions apply or legacy system maintenance.

ERJ-12SF1501U carries "Not For New Designs" status from Panasonic. While currently in stock with ROHS3 compliance, this part should be reserved for replacement or repair of existing assemblies only.

Packaging Considerations:

For automated tape-fed assembly processes, select Tape & Reel (TR) format parts: RMCS2010FT1K50, AC2010FK-071K5L, CRCW20101K50FKTF, ERJ-12SF1501U, or RC2010FK-071K5L.

For manual or cut-tape processes, RMCF2010FT1K50 or CRCW20101K50FKEF are appropriate.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT1K50 replace RMCS2010FT1K50 in my design?

A: Yes. Both parts share identical electrical specifications (1.5 kOhms ±1%, 0.75W, 2010 package, ±100ppm/°C, -55°C to 155°C). The primary difference is packaging format (Cut Tape vs. Tape & Reel) and RMCF2010FT1K50 includes Automotive AEC-Q200 qualification. Verify your assembly process supports the packaging format.

Q: What is the difference between AC2010FK-071K5L and RC2010FK-071K5L?

A: Both are YAGEO 1.5 kOhms ±1% 0.75W 2010 package resistors with identical electrical performance. AC2010FK-071K5L includes Automotive AEC-Q200 certification and Moisture Resistant features. RC2010FK-071K5L includes only Moisture Resistant features. Select AC2010FK-071K5L for automotive applications requiring AEC-Q200 compliance.

Q: Why is ERJ-12SF1501U marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued this part for new applications. While currently available in inventory, it should be used only for replacement or repair of existing assemblies. For new designs, select from active production alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: No. CRCW20101K50FKTF is RoHS non-compliant and REACH Affected. All other listed substitutes are ROHS3 Compliant and REACH Unaffected. Verify compliance requirements for your application before selection.

Q: Can I use CRCW20101K50FKEF and CRCW20101K50FKTF interchangeably?

A: Electrically yes, but with compliance considerations. Both are Vishay Dale CRCW series 1.5 kOhms ±1% 0.75W 2010 package parts with Automotive AEC-Q200 features. CRCW20101K50FKEF is ROHS3 Compliant (Cut Tape & Digi-Reel format), while CRCW20101K50FKTF is RoHS non-compliant (Tape & Reel format). Select based on your compliance requirements and packaging process.

Q: What is the maximum height difference among substitute parts?

A: Height specifications range from 0.026" (0.65mm) to 0.028" (0.70mm) seated maximum. This 0.002" (0.05mm) variation is within standard PCB assembly tolerances and does not affect interchangeability for standard applications.
