Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1608J245CS is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Resistance value: 2.4 MOhms (exact match required)
• Package format: 0603 (1608 Metric) (physical and electrical compatibility)
• Power rating: 0.1W minimum (equal or greater)
• Composition: Thick Film (electrical performance characteristics)
• Operating temperature range: -55°C ~ 155°C minimum (thermal compatibility)
• Moisture resistance: Required (environmental durability)

Direct Substitutes maintain identical tolerance (±5%) and temperature coefficient (±100ppm/°C) specifications.

Upgrade Substitutes offer enhanced tolerance (±1%) and automotive-grade AEC-Q200 qualification, suitable for applications requiring higher precision or automotive reliability standards. These parts are electrically and mechanically interchangeable while providing superior performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

RC0603JR-072M4L (YAGEO) functions as a direct equivalent to RC1608J245CS. Both components share identical electrical specifications including 2.4 MOhms resistance, ±5% tolerance, ±100ppm/°C temperature coefficient, and 0.1W power rating. Physical dimensions and package format are equivalent. Both maintain Active product status and ROHS3 compliance. This substitute is appropriate for applications where the original specification tolerance and performance characteristics are sufficient.

Upgrade Substitute Selection:

KTR03EZPF2404 (Rohm Semiconductor) and RMCF0603FT2M40 (Stackpole Electronics Inc) are upgrade substitutes offering ±1% tolerance compared to the original ±5% specification. Both components carry AEC-Q200 automotive qualification and maintain all other critical parameters including 2.4 MOhms resistance, 0.1W power rating, and -55°C ~ 155°C operating range. These substitutes are suitable for applications requiring enhanced precision or automotive-grade reliability standards.

RMCF0603FT2M40 exhibits ±200ppm/°C temperature coefficient compared to ±100ppm/°C in the original part. This parameter difference is within acceptable limits for most applications but should be evaluated in temperature-sensitive circuit designs.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical package format, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-072M4L replace RC1608J245CS without circuit redesign?

A: Yes. RC0603JR-072M4L is a direct equivalent with identical electrical and physical specifications. No circuit redesign is required. Both components share the same 2.4 MOhms resistance, ±5% tolerance, 0.1W power rating, and 0603 package format.

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

A: Direct substitutes (RC0603JR-072M4L) maintain identical tolerance (±5%) and temperature coefficient (±100ppm/°C). Upgrade substitutes (KTR03EZPF2404, RMCF0603FT2M40) offer improved tolerance (±1%) and automotive AEC-Q200 qualification. Upgrade substitutes are electrically and mechanically interchangeable while providing enhanced performance.

Q: Are the upgrade substitutes suitable for automotive applications?

A: KTR03EZPF2404 and RMCF0603FT2M40 carry AEC-Q200 automotive qualification. The original RC1608J245CS does not specify automotive grade. Upgrade substitutes are appropriate for automotive applications requiring AEC-Q200 compliance.

Q: Does the ±200ppm/°C temperature coefficient of RMCF0603FT2M40 affect compatibility?

A: RMCF0603FT2M40 maintains ±200ppm/°C temperature coefficient compared to ±100ppm/°C in RC1608J245CS and other substitutes. This difference should be evaluated in applications with strict temperature stability requirements. For most general-purpose applications, this parameter difference is acceptable.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in 0603 (1608 Metric) package format with Tape & Reel (TR) packaging. Physical dimensions are equivalent, ensuring direct PCB compatibility.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including the original RC1608J245CS and all substitutes, maintain MSL Level 1 (Unlimited) rating. This indicates unlimited shelf life under standard storage conditions without moisture bake-out requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. RC1608J245CS, RC0603JR-072M4L, KTR03EZPF2404, and RMCF0603FT2M40 are all ROHS3 compliant and REACH unaffected.
