Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2672CS is determined by strict equivalence across the following critical parameters: resistance value (26.7 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). Parts are grouped into three categories based on their substitution relationship:

Direct Substitutes maintain identical electrical and mechanical specifications, including power rating (0.063W), packaging format (Tape & Reel), and feature set. These parts are pin-compatible and functionally interchangeable without design modification.

Upgrade Substitutes provide enhanced power rating (0.1W vs. 0.063W) or additional certifications (AEC-Q200 automotive qualification) while maintaining all other critical parameters. These parts offer improved performance margins and are suitable for applications requiring higher reliability standards.

Similar Substitutes match all core electrical parameters but may include additional features such as automotive AEC-Q200 qualification or differ in packaging format (Cut Tape vs. Tape & Reel). These parts are functionally equivalent but may require verification of packaging compatibility with assembly equipment.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred for Standard Applications)

The CR0402-FX-2672GLF (Bourns Inc.) and RC0402FR-0726K7L (YAGEO) are direct functional equivalents to the RC1005F2672CS. Both parts maintain identical electrical specifications, package format, and RoHS3 compliance. The RC0402FR-0726K7L includes moisture-resistant construction matching the original part specification. Selection between these direct substitutes depends on packaging format compatibility: CR0402-FX-2672GLF is supplied in Tape & Reel format, while RC0402FR-0726K7L is available in Cut Tape & Digi-Reel format. Both are suitable for applications requiring standard industrial-grade thick film resistors without automotive qualification.

Upgrade Substitute (Enhanced Performance)

The ERJ-2RKF2672X (Panasonic Electronic Components) provides an upgrade path with increased power rating (0.1W vs. 0.063W) and automotive AEC-Q200 qualification. This part is suitable for applications requiring higher reliability margins or automotive-grade component certification. The higher power rating allows operation at elevated current levels without thermal stress, making this part appropriate for designs with potential power dissipation increases or thermal margin requirements.

Similar Substitutes (Automotive-Qualified Alternatives)

The AC0402FR-0726K7L (YAGEO), CRCW040226K7FKED (Vishay Dale), and RMCF0402FT26K7 (Stackpole Electronics Inc) are automotive AEC-Q200 qualified alternatives. These parts maintain identical electrical specifications and are suitable for automotive applications or designs requiring enhanced reliability certification. The AC0402FR-0726K7L includes moisture-resistant construction. All three parts are RoHS3 compliant and available in Tape & Reel packaging.

Non-Compliant Part (Restricted Use)

The CRCW040226K7FKTD (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is not suitable for applications subject to RoHS3 or REACH regulatory requirements and should be avoided for new designs targeting EU markets or regulated industries.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1005F2672CS with any of the listed equivalent parts without design modification?

A: Direct substitutes (CR0402-FX-2672GLF and RC0402FR-0726K7L) are pin-compatible and functionally interchangeable without design modification. Upgrade substitutes (ERJ-2RKF2672X) and automotive-qualified alternatives (AC0402FR-0726K7L, CRCW040226K7FKED, RMCF0402FT26K7) are also electrically compatible but may require verification of assembly equipment compatibility with packaging format.

Q: What is the difference between the direct substitute and the upgrade substitute?

A: The direct substitutes (CR0402-FX-2672GLF, RC0402FR-0726K7L) maintain identical 0.063W power rating and standard industrial specifications. The upgrade substitute (ERJ-2RKF2672X) provides 0.1W power rating and automotive AEC-Q200 qualification, offering higher reliability margins and automotive-grade certification. The upgrade substitute is suitable for applications requiring enhanced performance or automotive compliance.

Q: Are all substitute parts RoHS3 compliant?

A: Six of the seven substitute parts are RoHS3 compliant. The CRCW040226K7FKTD is RoHS non-compliant and REACH-affected and should not be used in applications subject to RoHS3 or REACH regulatory requirements.

Q: What is the significance of the packaging format difference between Tape & Reel and Cut Tape & Digi-Reel?

A: Packaging format affects assembly equipment compatibility and handling procedures. Tape & Reel format is standard for automated pick-and-place assembly systems. Cut Tape & Digi-Reel format (RC0402FR-0726K7L) is suitable for lower-volume production or manual assembly. Verify assembly equipment specifications before selecting parts with different packaging formats.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select from the AEC-Q200 qualified parts: ERJ-2RKF2672X (upgrade with 0.1W rating), AC0402FR-0726K7L (with moisture resistance), CRCW040226K7FKED, or RMCF0402FT26K7. All four parts meet automotive reliability standards and are RoHS3 compliant.

Q: Can I use the ERJ-2RKF2672X as a direct replacement for the RC1005F2672CS?

A: Yes, the ERJ-2RKF2672X is electrically compatible and can be used as a direct replacement. The higher power rating (0.1W vs. 0.063W) provides additional thermal margin and is not detrimental to circuit operation. This part is suitable when enhanced reliability or automotive qualification is required.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: resistance value (26.7 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). All listed substitute parts meet these core requirements.
