Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F6040CS is determined by strict alignment with the following core parameters: resistance value (604 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Substitute parts are categorized into three groups:

Direct Substitutes maintain identical electrical and mechanical specifications, including package size, power rating (1/16W), and moisture-resistant features. These parts are pin-compatible and footprint-compatible with no design modifications required.

Upgrade Substitutes provide enhanced power rating (1/10W instead of 1/16W) while maintaining the same package footprint (0402), resistance, tolerance, and temperature characteristics. These parts support higher power dissipation in the same physical space and are suitable for designs requiring additional thermal margin.

Similar Substitutes match core electrical parameters and package format but introduce additional certifications (AEC-Q200 automotive qualification) or alternative moisture-resistant features. These parts are functionally equivalent but may carry different compliance profiles or regulatory status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Pin and Footprint Compatible):

CR0402-FX-6040GLF (Bourns Inc.) and RC0402FR-07604RL (YAGEO) are direct equivalents to RC1005F6040CS. Both maintain identical electrical specifications, package dimensions, and power rating. RC0402FR-07604RL includes moisture-resistant construction matching the original part. Both are ROHS3 compliant and suitable for immediate replacement without PCB layout modifications.

For Automotive Applications Requiring AEC-Q200 Certification:

AC0402FR-07604RL (YAGEO), CRCW0402604RFKED (Vishay Dale), and RMCF0402FT604R (Stackpole Electronics Inc) provide AEC-Q200 automotive qualification while maintaining 0402 package format and 1/16W power rating. AC0402FR-07604RL additionally includes moisture-resistant features. All three are ROHS3 compliant. These parts are suitable for automotive-grade designs requiring qualification documentation.

For Enhanced Power Dissipation in Same Footprint:

ERJ-2RKF6040X (Panasonic Electronic Components) provides 1/10W (0.1W) power rating in the same 0402 package, representing a 58% increase in power handling capacity. This upgrade maintains identical resistance, tolerance, temperature coefficient, and operating range while adding AEC-Q200 automotive certification. ROHS3 compliant. Select this part when thermal margin or higher power dissipation is required without changing PCB footprint.

For Larger Package Format with Enhanced Power:

ERJ-3EKF6040V (Panasonic Electronic Components) provides 1/10W power rating in 0603 (1608 Metric) package with AEC-Q200 certification. This part requires PCB layout modification due to larger footprint (0.063" L x 0.031" W versus 0.039" L x 0.020" W). Select only when PCB space permits and enhanced power handling is necessary.

Compliance Consideration:

CRCW0402604RFKTD (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring ROHS3 compliance or REACH compliance. Avoid selection unless legacy system requirements explicitly permit non-compliant components.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6040GLF replace RC1005F6040CS without design changes?

A: Yes. CR0402-FX-6040GLF is a direct substitute with identical resistance (604 Ω), tolerance (±1%), power rating (1/16W), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). No PCB modifications are required. Both parts are ROHS3 compliant.

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

A: Direct substitutes (CR0402-FX-6040GLF, RC0402FR-07604RL) maintain all electrical and mechanical specifications identical to RC1005F6040CS. Upgrade substitutes (ERJ-2RKF6040X) increase power rating from 1/16W to 1/10W while preserving package footprint and all other parameters. Upgrade substitutes are suitable when higher power dissipation is required in the same physical space.

Q: Why does ERJ-3EKF6040V require PCB layout modification?

A: ERJ-3EKF6040V uses 0603 (1608 Metric) package format with dimensions 0.063" L x 0.031" W, compared to 0402 package dimensions of 0.039" L x 0.020" W. The larger footprint requires different PCB pad layout and component placement. This part is suitable only when PCB space permits the larger package.

Q: Are all substitute parts ROHS3 compliant?

A: No. CRCW0402604RFKTD (Vishay Dale) is RoHS non-compliant and REACH affected. All other substitute parts listed are ROHS3 compliant and REACH unaffected. Verify compliance requirements before part selection.

A: ERJ-2RKF6040X, ERJ-3EKF6040V, AC0402FR-07604RL, CRCW0402604RFKED, CRCW0402604RFKTD, and RMCF0402FT604R all include AEC-Q200 automotive qualification. Select these parts for automotive-grade applications requiring qualification documentation.

Q: Does RC0402FR-07604RL include moisture-resistant features like the original part?

A: Yes. RC0402FR-07604RL includes moisture-resistant construction matching RC1005F6040CS. Both parts maintain identical moisture sensitivity level (MSL 1 - Unlimited) and are suitable for applications requiring moisture protection.

Q: Can ERJ-2RKF6040X be used as a direct replacement without PCB changes?

A: Yes. ERJ-2RKF6040X maintains the same 0402 package footprint as RC1005F6040CS. The primary difference is increased power rating (1/10W versus 1/16W). No PCB layout modifications are required. This part is suitable for designs requiring enhanced thermal performance in the same footprint.
