Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6492CS is determined by strict equivalence across the following critical parameters: resistance value (64.9 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All substitute parts listed maintain these core electrical and mechanical specifications. Substitute parts are categorized as follows:

Direct Substitutes maintain identical power ratings (0.063W / 1/16W), packaging format (Cut Tape or Tape & Reel), and moisture resistant characteristics where applicable.

Upgrade Substitutes provide enhanced power ratings (0.1W / 1/10W) while maintaining all other core parameters, suitable for applications requiring higher thermal headroom.

Similar Substitutes include automotive-qualified variants (AEC-Q200) that meet or exceed the base electrical specifications and compliance requirements of the original part.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC0402FR-0764K9L (YAGEO) and CR0402-FX-6492GLF (Bourns Inc.) provide direct electrical and mechanical equivalence to the RC1005F6492CS. Both maintain ROHS3 compliance and identical power ratings. Selection between these options depends on packaging preference (Cut Tape vs. Tape & Reel) and inventory availability.

For Automotive Applications: AC0402FR-0764K9L (YAGEO), CRCW040264K9FKED (Vishay Dale), and RMCF0402FT64K9 (Stackpole Electronics Inc.) are qualified to AEC-Q200 automotive standards while maintaining electrical equivalence. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability qualification.

For Enhanced Thermal Performance: ERJ-2RKF6492X (Panasonic Electronic Components) offers a 0.1W (1/10W) power rating compared to the 0.063W (1/16W) of the original part, providing increased thermal margin in applications subject to higher power dissipation. This upgrade maintains AEC-Q200 automotive qualification and ROHS3 compliance.

Compliance Considerations: CRCW040264K9FKTD (Vishay Dale) is RoHS non-compliant and REACH affected; this part is suitable only for applications where such compliance is not required. All other substitute parts maintain ROHS3 compliance and REACH unaffected status consistent with the original RC1005F6492CS.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0764K9L be used as a direct replacement for RC1005F6492CS?

A: Yes. RC0402FR-0764K9L maintains identical resistance (64.9 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1. The primary difference is packaging format (Cut Tape & Digi-Reel® vs. Cut Tape), which does not affect electrical performance.

Q: What is the difference between the Bourns CR0402-FX-6492GLF and YAGEO RC0402FR-0764K9L?

A: Both parts are electrically and mechanically equivalent to the RC1005F6492CS. The CR0402-FX-6492GLF is supplied in Tape & Reel format, while RC0402FR-0764K9L is available in Cut Tape & Digi-Reel® format. Selection depends on assembly process requirements and packaging preferences. Inventory levels differ between manufacturers.

Q: When should ERJ-2RKF6492X be selected over the standard 0.063W rating?

A: ERJ-2RKF6492X provides a 0.1W (1/10W) power rating, offering increased thermal headroom for applications where the resistor dissipates higher power levels or operates in elevated ambient temperatures. This upgrade is suitable when thermal analysis indicates the standard 0.063W rating approaches or exceeds design margins. The part maintains all other electrical specifications and adds AEC-Q200 automotive qualification.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. Automotive-qualified parts such as AC0402FR-0764K9L, CRCW040264K9FKED, and RMCF0402FT64K9 meet or exceed the electrical and reliability specifications of non-automotive equivalents. These parts are suitable for any application requiring the specified electrical characteristics, regardless of automotive qualification status.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity?

A: MSL 1 indicates unlimited shelf life and no moisture bake-out requirement prior to soldering. All listed substitute parts maintain MSL 1 rating, ensuring compatibility with standard storage and assembly processes without special handling procedures.

Q: Why is CRCW040264K9FKTD marked as RoHS non-compliant?

A: CRCW040264K9FKTD does not meet ROHS3 compliance requirements and is REACH affected. This part is suitable only for applications or markets where RoHS compliance is not mandated. For applications requiring ROHS3 compliance, select alternative substitutes such as RMCF0402FT64K9, AC0402FR-0764K9L, or CRCW040264K9FKED.

Q: Can these 0402 package resistors be used interchangeably on PCBs designed for the RC1005F6492CS?

A: Yes. All substitute parts maintain the 0402 (1005 Metric) package format with identical footprint dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm, with AC0402FR-0764K9L at 0.015" / 0.37mm). PCB layout and assembly processes require no modification.
