Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMCS2010JT2R20 are qualified based on the following critical parameters that determine functional equivalence:

• Resistance value: 2.2 Ohms (exact match required)
• Power rating: 0.75W minimum
• Package / Case: 2010 (5025 Metric) form factor
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thick film construction
• RoHS3 compliance and MSL Level 1 rating

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in tolerance (±1% vs ±5%), features (automotive AEC-Q200 certification, pulse withstanding capability, moisture resistance), and packaging format (Tape & Reel vs Cut Tape) are secondary differentiators that do not affect functional substitution within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RMCS2010JT2R20 within the specified parameter envelope. Selection among these alternatives is determined by application-specific requirements and compliance certifications:

RPC2010JT2R20 (Stackpole Electronics Inc) is the manufacturer-recommended primary substitute, offering identical specifications with added automotive AEC-Q200 qualification and pulse withstanding capability for applications requiring enhanced reliability in automotive environments.

CRCW20102R20JNEF (Vishay Dale) provides automotive AEC-Q200 certification with equivalent electrical performance. The maximum seated height of 0.028" (0.70mm) represents a 0.002" increase compared to the primary part and must be evaluated for PCB clearance constraints in space-limited applications.

RC2010FK-072R2L (YAGEO) offers improved tolerance specification at ±1% compared to the ±5% tolerance of the primary part, suitable for applications requiring tighter resistance accuracy. Moisture-resistant construction provides enhanced environmental protection.

RC2010JK-072R2L (YAGEO) matches the ±5% tolerance specification of the primary part with moisture-resistant construction and represents the highest inventory availability among all substitutes.

All substitute parts are Active product status with RoHS3 compliance and MSL Level 1 rating, ensuring regulatory alignment and unlimited moisture sensitivity protection.

Frequently Asked Questions (FAQ)

Q: Can RPC2010JT2R20 be used as a direct replacement for RMCS2010JT2R20?

A: Yes. RPC2010JT2R20 maintains identical electrical specifications (2.2 Ohms ±5%, 0.75W), package form factor (2010 / 5025 Metric), temperature coefficient (±200ppm/°C), and operating range (-55°C ~ 155°C). Both are manufactured by Stackpole Electronics Inc and are RoHS3 compliant with MSL Level 1 rating. The primary difference is the addition of automotive AEC-Q200 qualification and pulse withstanding capability in the RPC series.

Q: What is the significance of the ±1% tolerance in RC2010FK-072R2L compared to the ±5% tolerance of RMCS2010JT2R20?

A: Tolerance specification defines the acceptable resistance variation from the nominal 2.2 Ohm value. RC2010FK-072R2L with ±1% tolerance provides tighter resistance accuracy (±0.022 Ohms) compared to RMCS2010JT2R20 with ±5% tolerance (±0.11 Ohms). Selection depends on circuit requirements for resistance precision. Applications with strict impedance or voltage divider specifications may benefit from the tighter tolerance.

Q: Does the 0.002" height difference in CRCW20102R20JNEF affect PCB compatibility?

A: CRCW20102R20JNEF has a maximum seated height of 0.028" (0.70mm) compared to 0.026" (0.65mm) for RMCS2010JT2R20. This 0.002" difference is within typical PCB design tolerances but must be evaluated for applications with height-constrained layouts, such as low-profile assemblies or designs with minimal clearance above the component.

Q: Are all substitute parts suitable for automotive applications?

A: RPC2010JT2R20 and CRCW20102R20JNEF carry automotive AEC-Q200 certification, qualifying them for automotive-grade applications. RMCS2010JT2R20, RC2010FK-072R2L, and RC2010JK-072R2L do not carry explicit automotive certification but maintain the same electrical specifications and temperature operating range. Application requirements determine whether automotive certification is mandatory.

Q: What packaging format differences exist among the substitute parts?

A: RMCS2010JT2R20, RPC2010JT2R20, RC2010FK-072R2L, and RC2010JK-072R2L are supplied in Tape & Reel (TR) format. CRCW20102R20JNEF is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance of the component itself.

Q: Can these parts be used interchangeably in existing designs without PCB modification?

A: Yes, all substitute parts are mechanically and electrically compatible with the 2010 (5025 Metric) package footprint. No PCB redesign is required for substitution. The 0.002" height variation in CRCW20102R20JNEF should be evaluated for clearance constraints, but standard PCB design tolerances accommodate this variation without modification.
