Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F3651CS is determined by strict equivalence across the following critical parameters: resistance value (3.65 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Power rating, while a key specification, permits substitution with equal or higher rated devices. Moisture sensitivity level (MSL 1) and termination count (2) must remain constant. RoHS compliance status and REACH regulatory status are documented but do not restrict substitution eligibility when equivalent electrical and mechanical parameters are met. Packaging format (Tape & Reel or Cut Tape) does not affect electrical equivalence but may impact procurement logistics.

The substitute parts are organized into three categories:

Direct Equivalents: Parts with identical electrical specifications, power rating, and packaging that provide one-to-one replacement capability.

Upgrade Substitutes: Parts with superior power rating or enhanced qualification standards (such as AEC-Q200 automotive certification) that maintain all other electrical parameters.

Similar Substitutes: Parts meeting all core electrical and mechanical requirements with variations in features (automotive qualification, moisture resistance designation) or regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-3651GLF (Bourns Inc.) and RC0402FR-073K65L (YAGEO) provide direct electrical and mechanical equivalence to the RC1005F3651CS. Both parts maintain identical resistance, tolerance, power rating, package format, and temperature specifications. RC0402FR-073K65L includes moisture resistant designation matching the original part. Both are ROHS3 compliant with active product status.

Upgrade Path: ERJ-2RKF3651X (Panasonic Electronic Components) offers enhanced power rating of 0.1W (1/10W) compared to the 0.063W specification of the main part, with automotive AEC-Q200 qualification. This part is suitable for applications requiring higher thermal margin or automotive-grade reliability while maintaining all other electrical parameters.

Automotive-Qualified Alternatives: AC0402FR-073K65L (YAGEO), CRCW04023K65FKED (Vishay Dale), and RMCF0402FT3K65 (Stackpole Electronics Inc) are all AEC-Q200 qualified with ROHS3 compliance. These parts are appropriate for automotive and high-reliability applications. AC0402FR-073K65L additionally includes moisture resistant construction. RMCF0402FT3K65 offers the highest inventory availability (445,747 pieces).

Regulatory Compliance Note: CRCW04023K65FKTD (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring ROHS3 compliance or REACH compliance verification.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1005F3651CS with CR0402-FX-3651GLF?

A: Yes. CR0402-FX-3651GLF is a direct equivalent with identical resistance (3.65 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between RC0402FR-073K65L and RC1005F3651CS?

A: RC0402FR-073K65L is electrically and mechanically equivalent to RC1005F3651CS. The primary difference is packaging format: RC0402FR-073K65L is supplied in Cut Tape & Digi-Reel format, while RC1005F3651CS is supplied in Tape & Reel format. Both include moisture resistant construction and are ROHS3 compliant.

Q: Can I use ERJ-2RKF3651X as a substitute?

A: Yes, with the following consideration: ERJ-2RKF3651X has a higher power rating (0.1W versus 0.063W). This is an upgrade substitute suitable for applications where thermal margin is beneficial. All other electrical parameters (resistance, tolerance, temperature coefficient, operating range) are identical. The part includes automotive AEC-Q200 qualification.

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

A: Yes. Automotive-qualified parts meet or exceed the electrical and mechanical specifications of standard industrial-grade parts. AC0402FR-073K65L, CRCW04023K65FKED, and RMCF0402FT3K65 are all AEC-Q200 qualified and fully compatible with non-automotive applications.

Q: Why is CRCW04023K65FKTD marked as RoHS non-compliant?

A: CRCW04023K65FKTD does not meet ROHS3 compliance requirements and is REACH affected. This part should not be used in applications requiring RoHS compliance certification. Use CRCW04023K65FKED (ROHS3 compliant variant) instead.

Q: What is the difference between moisture resistant and non-moisture resistant variants?

A: RC1005F3651CS and RC0402FR-073K65L include moisture resistant construction, which provides enhanced protection in humid environments. CR0402-FX-3651GLF does not specify moisture resistant features. Both types have MSL 1 (unlimited) rating, indicating low moisture sensitivity. Selection depends on application environment requirements.

Q: Can I mix packaging formats (Tape & Reel vs. Cut Tape) in production?

A: Packaging format does not affect electrical or mechanical compatibility. However, procurement and assembly processes may differ. Tape & Reel format is standard for automated pick-and-place assembly, while Cut Tape format is suitable for manual assembly or lower-volume applications. Verify compatibility with your assembly equipment and procurement workflow.

Q: Which substitute part has the highest inventory availability?

A: RMCF0402FT3K65 (Stackpole Electronics Inc) has the highest inventory availability at 445,747 pieces. This part is ROHS3 compliant, AEC-Q200 qualified, and electrically equivalent to the main part.
