Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1005F1691CS is determined by strict equivalence across the following parameters: resistance value (1.69 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and termination count (2).

Substitute parts are categorized into three groups:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, including power rating (0.063W / 1/16W), moisture resistance features, and packaging format (Tape & Reel).

Upgrade Substitutes provide enhanced specifications, specifically increased power rating (0.1W / 1/10W) while maintaining all other core parameters, and include automotive AEC-Q200 qualification.

Similar Substitutes match all core electrical parameters and package specifications but may include additional certifications (automotive AEC-Q200) or differ in packaging format (Cut Tape vs. Tape & Reel) or minor dimensional variations (height-seated maximum).

All substitute parts listed maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status unless otherwise specified.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-1691GLF (Bourns Inc.) and RC0402FR-071K69L (YAGEO) are direct functional equivalents to the RC1005F1691CS. Both maintain identical electrical specifications, package format, and power rating. RC0402FR-071K69L includes moisture-resistant features matching the original part. CR0402-FX-1691GLF provides equivalent performance without specified moisture resistance features. Both are ROHS3 compliant with MSL 1 rating.

Upgrade Selection: ERJ-2RKF1691X (Panasonic Electronic Components) provides enhanced power rating (0.1W vs. 0.063W) while maintaining all other core specifications. This part includes automotive AEC-Q200 qualification and is suitable for applications requiring higher thermal margin or automotive-grade reliability. ROHS3 compliant.

Automotive-Qualified Selection: AC0402FR-071K69L (YAGEO), CRCW04021K69FKED (Vishay Dale), and RMCF0402FT1K69 (Stackpole Electronics Inc) are automotive AEC-Q200 qualified alternatives. AC0402FR-071K69L combines automotive qualification with moisture-resistant construction. CRCW04021K69FKED and RMCF0402FT1K69 provide automotive qualification at standard specifications. All three are ROHS3 compliant.

Compliance Consideration: CRCW04021K69FKTD (Vishay Dale) is not ROHS3 compliant and is REACH affected. This part is not recommended for new designs or applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1691GLF replace RC1005F1691CS in all applications?

A: CR0402-FX-1691GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (1.69 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The primary difference is that CR0402-FX-1691GLF does not specify moisture-resistant features. For applications where moisture resistance is not a design requirement, this part is fully interchangeable.

Q: What is the difference between the main part and RC0402FR-071K69L?

A: RC0402FR-071K69L is electrically and mechanically identical to RC1005F1691CS. Both are 1.69 kOhms ±1% thick film resistors in 0402 package with 0.063W power rating and moisture-resistant construction. The difference is packaging format: RC1005F1691CS is supplied in Tape & Reel format, while RC0402FR-071K69L is available in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: When should ERJ-2RKF1691X be used instead of the original part?

A: ERJ-2RKF1691X is an upgrade substitute with increased power rating (0.1W vs. 0.063W). Use this part when the application requires higher power dissipation capability or when automotive AEC-Q200 qualification is mandatory. All other electrical parameters remain identical. The higher power rating provides additional thermal margin without changing circuit behavior.

Q: Are automotive AEC-Q200 qualified parts interchangeable with the standard RC1005F1691CS?

A: Yes. AC0402FR-071K69L, CRCW04021K69FKED, and RMCF0402FT1K69 are all electrically and mechanically equivalent to RC1005F1691CS with the addition of automotive AEC-Q200 qualification. These parts meet all specifications of the original part and include enhanced reliability testing required for automotive applications. They are suitable for both automotive and non-automotive applications.

Q: Why is CRCW04021K69FKTD not recommended?

A: CRCW04021K69FKTD is not ROHS3 compliant and is REACH affected. For new designs and applications subject to regulatory compliance requirements, this part does not meet current environmental standards. CRCW04021K69FKED (ROHS3 compliant variant) is the recommended alternative from Vishay Dale.

Q: What packaging format considerations apply to substitute selection?

A: The main part RC1005F1691CS is supplied in Tape & Reel format. Most substitute parts (CR0402-FX-1691GLF, ERJ-2RKF1691X, AC0402FR-071K69L, CRCW04021K69FKED, CRCW04021K69FKTD, RMCF0402FT1K69) are also Tape & Reel packaged. RC0402FR-071K69L is available in Cut Tape & Digi-Reel format. Verify packaging compatibility with assembly equipment before selection.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed substitute parts maintain MSL 1 (Unlimited) rating, identical to the main part RC1005F1691CS. This indicates no moisture sensitivity restrictions for storage or handling.

Q: What is the temperature coefficient specification and does it vary among substitutes?

A: All parts listed, including the main part and all substitutes, have a temperature coefficient of ±100ppm/°C. This specification is consistent across all options and does not vary.
