Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1621CS is determined by strict equivalence across the following critical parameters: resistance value (1.62 kOhms), tolerance (±1%), package format (0402), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts listed maintain these core electrical and mechanical specifications.

Substitute parts are categorized into three groups:

Direct Equivalents: Parts with identical specifications including power rating (0.063W), moisture resistance features, and compliance certifications. These parts are pin-compatible and functionally interchangeable without circuit redesign.

Upgrade Equivalents: Parts with enhanced power rating (0.1W instead of 0.063W) while maintaining all other electrical parameters. These provide improved thermal margin in the same package footprint.

Similar Equivalents: Parts with automotive AEC-Q200 certification added to the base specification. These meet enhanced reliability and qualification standards suitable for automotive applications while maintaining electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0402-FX-1621GLF (Bourns Inc.) and RC0402FR-071K62L (YAGEO) are direct functional equivalents with high inventory availability. RC0402FR-071K62L includes moisture-resistant construction matching the original specification. Both maintain ROHS3 compliance and identical electrical performance.

For Enhanced Thermal Performance: ERJ-2RKF1621X (Panasonic Electronic Components) provides 0.1W power rating in the same 0402 package, offering increased thermal margin while maintaining all other electrical parameters. This upgrade is suitable for applications requiring additional power dissipation headroom.

For Automotive Applications: AC0402FR-071K62L (YAGEO), CRCW04021K62FKED (Vishay Dale), and RMCF0402FT1K62 (Stackpole Electronics Inc) include AEC-Q200 automotive qualification. AC0402FR-071K62L combines automotive certification with moisture-resistant features. All three maintain ROHS3 compliance and identical electrical specifications to the base part.

Compliance Consideration: CRCW04021K62FKTD (Vishay Dale) is RoHS non-compliant and REACH-affected. This part is suitable only for applications where legacy component specifications are required and regulatory exemptions apply.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1621GLF replace RC1005F1621CS directly in production?

A: Yes. CR0402-FX-1621GLF maintains identical electrical specifications (1.62 kΩ ±1%, 0.063W, ±100ppm/°C, -55°C to 155°C) and 0402 package format. Both are ROHS3 compliant with MSL 1 rating. The primary difference is the absence of explicit moisture-resistant designation in the Bourns part, though MSL 1 rating indicates unlimited moisture sensitivity protection.

Q: What is the difference between the direct equivalents and the upgrade part ERJ-2RKF1621X?

A: ERJ-2RKF1621X increases power rating from 0.063W to 0.1W while maintaining all other electrical parameters. This provides enhanced thermal performance in the same 0402 footprint. The upgrade is electrically compatible and suitable for applications requiring higher power dissipation capability.

Q: Are the automotive-qualified parts (AEC-Q200) backward compatible with standard applications?

A: Yes. Automotive-qualified parts (AC0402FR-071K62L, CRCW04021K62FKED, RMCF0402FT1K62) maintain identical electrical specifications and 0402 package format. AEC-Q200 certification represents enhanced qualification and reliability testing, making these parts suitable for both automotive and standard industrial applications.

Q: Why is CRCW04021K62FKTD marked as RoHS non-compliant?

A: CRCW04021K62FKTD carries RoHS non-compliant status and REACH-affected designation. This part is functionally equivalent but restricted to applications where legacy component specifications or regulatory exemptions apply. ROHS3-compliant alternatives are available for new designs.

Q: Can I use RC0402FR-071K62L as a direct replacement for RC1005F1621CS?

A: Yes. RC0402FR-071K62L (YAGEO) is a direct equivalent with identical specifications including 1.62 kΩ ±1%, 0.063W power rating, moisture-resistant construction, and ROHS3 compliance. Both parts are functionally interchangeable in circuit design and PCB layout.

Q: What inventory considerations apply when selecting substitute parts?

A: RC0402FR-071K62L offers the highest inventory availability (188,154 pieces), followed by ERJ-2RKF1621X (107,649 pieces) and RMCF0402FT1K62 (52,612 pieces). CR0402-FX-1621GLF (37,297 pieces) and AC0402FR-071K62L (36,209 pieces) provide moderate availability. CRCW04021K62FKTD has the lowest inventory (10,370 pieces).
