Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F3481CS are classified based on strict electrical and mechanical parameter matching. All substitute candidates maintain the following core specifications: 3.48 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Substitution categories are defined as follows:

Direct Substitutes maintain identical electrical ratings (0.063W power), packaging format (cut tape or tape & reel), and moisture resistant properties where applicable. These parts are functionally interchangeable without circuit redesign.

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

Similar Substitutes match all core electrical specifications and package format but may include automotive qualification (AEC-Q200) or alternative moisture resistant features. These parts are compatible with the original design and support supply chain alternatives.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0402-FX-3481GLF (Bourns Inc.) and RC0402FR-073K48L (YAGEO) are direct functional equivalents. Both maintain ROHS3 compliance and identical electrical specifications. RC0402FR-073K48L includes moisture resistant construction matching the original part. Selection between these options depends on packaging format requirements (tape & reel availability) and supply chain preferences.

For Automotive and High-Reliability Applications: ERJ-2RKF3481X (Panasonic), AC0402FR-073K48L (YAGEO), CRCW04023K48FKED (Vishay Dale), and RMCF0402FT3K48 (Stackpole Electronics Inc) all provide AEC-Q200 automotive qualification. ERJ-2RKF3481X offers enhanced power rating (0.1W) for applications requiring additional thermal margin. AC0402FR-073K48L combines automotive qualification with moisture resistant construction. RMCF0402FT3K48 provides the highest inventory availability (226,079 units) among automotive-qualified options.

Compliance Considerations: CRCW04023K48FKTD (Vishay Dale) is not ROHS3 compliant and is REACH affected; this part is not recommended for new designs or applications with regulatory compliance requirements. All other substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original RC1005F3481CS specifications.

Packaging Format: The original part is supplied in cut tape format. All substitute parts are available in tape & reel packaging, which is standard for high-volume production environments. Tape & reel format is compatible with automated assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3481GLF replace RC1005F3481CS in existing designs?

A: Yes. CR0402-FX-3481GLF maintains identical electrical specifications (3.48 kΩ, ±1%, 0.063W, ±100ppm/°C) and 0402 package format. The primary difference is packaging format (tape & reel instead of cut tape) and absence of explicitly stated moisture resistant features. Electrical performance and circuit compatibility are equivalent.

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

A: Direct substitutes maintain all electrical and physical specifications of the original part. Upgrade substitutes provide enhanced performance characteristics, such as ERJ-2RKF3481X with 0.1W power rating (versus 0.063W) or automotive AEC-Q200 qualification. Upgrade substitutes are backward compatible and suitable for applications requiring higher reliability margins.

Q: Are AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. Parts meeting automotive standards are suitable for any application and provide additional performance assurance. AEC-Q200 qualified substitutes (AC0402FR-073K48L, CRCW04023K48FKED, RMCF0402FT3K48) are compatible with the original design and offer improved reliability.

Q: Why is CRCW04023K48FKTD not recommended?

A: CRCW04023K48FKTD is not ROHS3 compliant and is REACH affected, failing to meet current regulatory requirements for new designs and production. The functionally equivalent CRCW04023K48FKED (ROHS3 compliant, REACH unaffected) is the recommended Vishay Dale alternative.

Q: What is the significance of moisture resistant construction?

A: Moisture resistant thick film construction (RC1005F3481CS, RC0402FR-073K48L, AC0402FR-073K48L) provides enhanced protection in humid environments and applications with exposure to moisture. Non-moisture resistant alternatives (CR0402-FX-3481GLF) are suitable for controlled manufacturing and storage environments. Selection depends on end-use environmental conditions.

Q: Are all substitute parts available in tape & reel packaging?

A: Yes. All substitute parts listed are available in tape & reel packaging, which is standard for automated assembly. The original RC1005F3481CS is supplied in cut tape format. Tape & reel format is compatible with pick-and-place equipment and high-volume production workflows.

Q: Can substitute parts with higher power ratings be used in place of the original 0.063W part?

A: Yes. ERJ-2RKF3481X with 0.1W rating is a direct upgrade substitute. Higher power rating provides additional thermal margin and is fully backward compatible. Circuit performance remains unchanged; the component simply operates with lower thermal stress.

Q: What inventory considerations apply to substitute selection?

A: RMCF0402FT3K48 (Stackpole Electronics Inc) offers the highest inventory availability at 226,079 units. RC0402FR-073K48L (YAGEO) provides 115,222 units. CR0402-FX-3481GLF (Bourns Inc.) has 15,637 units available. Inventory levels support supply chain planning and lead time management.
