Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608J2R4CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.4 Ohms
• Power rating: 0.1W (1/10W)
• Package format: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Allowable Variation Parameters:

• Tolerance: ±5% (main part) to ±1% (substitute) — tighter tolerance is acceptable
• Temperature coefficient: ±300ppm/°C (main part) to ±200ppm/°C (substitute) — lower coefficient is acceptable
• Physical dimensions: Minor variations within 0603 package specification are acceptable
• Certifications: Additional automotive-grade (AEC-Q200) certification does not disqualify substitution

The substitute parts identified below meet all mandatory parameters and represent direct functional equivalents with equal or superior electrical characteristics.

Engineering Selection Recommendations

RMCF0603JT2R40 (Stackpole Electronics Inc)

This substitute provides direct functional equivalence to the RC1608J2R4CS with identical tolerance (±5%) and power rating (0.1W). The RMCF0603JT2R40 maintains the same operating temperature range (-55°C to 155°C) and achieves superior temperature stability with ±200ppm/°C coefficient. AEC-Q200 automotive certification qualifies this part for applications requiring automotive-grade reliability. Physical dimensions (1.55mm x 0.80mm) remain within 0603 package specification. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for direct substitution in all applications where the RC1608J2R4CS is specified.

RMCF0603FT2R40 (Stackpole Electronics Inc)

This substitute offers enhanced tolerance specification (±1% versus ±5%) while maintaining all other critical parameters. The tighter tolerance provides improved circuit accuracy and is suitable for applications requiring precision resistor networks. Temperature coefficient (±200ppm/°C) exceeds the performance of the main part. AEC-Q200 automotive certification and ROHS3 compliance are provided. Physical dimensions and thermal characteristics remain equivalent. This part is suitable for direct substitution in applications where tolerance improvement is beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603JT2R40 or RMCF0603FT2R40 be used as direct replacements for RC1608J2R4CS on existing PCBs?

A: Yes. Both Stackpole parts are direct substitutes. Physical dimensions (1.55mm x 0.80mm versus 1.60mm x 0.80mm) remain within 0603 package tolerance. Electrical parameters (resistance, power rating, operating temperature range) are identical. Tape & Reel packaging format is consistent across all three parts.

Q: What is the difference between RMCF0603JT2R40 and RMCF0603FT2R40?

A: The primary difference is tolerance specification. RMCF0603JT2R40 maintains ±5% tolerance matching the RC1608J2R4CS. RMCF0603FT2R40 provides ±1% tolerance for applications requiring higher precision. Both parts share identical power rating, operating temperature range, temperature coefficient (±200ppm/°C), and AEC-Q200 certification.

Q: Are the Stackpole substitutes suitable for automotive applications?

A: Yes. Both RMCF0603JT2R40 and RMCF0603FT2R40 carry AEC-Q200 automotive-grade certification. The RC1608J2R4CS does not carry this certification. If automotive qualification is required, either Stackpole part is appropriate.

Q: Does the temperature coefficient difference affect circuit performance?

A: The RC1608J2R4CS operates at ±300ppm/°C while both Stackpole substitutes operate at ±200ppm/°C. The lower coefficient in substitute parts indicates superior temperature stability. For applications sensitive to resistance drift across temperature extremes (-55°C to 155°C), the Stackpole parts provide improved performance.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC1608J2R4CS, RMCF0603JT2R40, and RMCF0603FT2R40 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the inventory status of substitute parts?

A: RMCF0603JT2R40 has 1017 pieces in stock. RMCF0603FT2R40 has 44091 pieces in stock. RC1608J2R4CS has 848 pieces in stock.
