Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPC0603JT4K70 is determined by the following critical parameters:

Core Compatibility Requirements:

• Resistance value: 4.7 kOhms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Allowable Variations:

• Tolerance: ±5% (main part) to ±1% (upgrade acceptable; tighter tolerance is backward compatible)
• Power rating: 0.1W (main part) to 0.25W (upgrade acceptable; higher power rating provides margin)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (format change acceptable for logistics)
• Features: Pulse Withstanding, Moisture Resistant, or Anti-Sulfur (feature additions acceptable)

All substitute parts listed maintain identical electrical performance within the specified operating envelope while offering either improved tolerance specifications, higher power dissipation capability, or alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

ESR03EZPF4701 (Rohm Semiconductor): This substitute offers upgraded tolerance specification (±1% versus ±5%) and increased power rating (0.25W versus 0.1W). Both improvements provide enhanced performance margin in circuit applications. The part maintains full AEC-Q200 automotive compliance, ROHS3 certification, and identical operating temperature range. Selection of this upgrade is appropriate when tighter resistance tolerance or higher thermal dissipation capability is required within the same physical footprint.

AC0603JR-074K7L (YAGEO): This substitute maintains identical electrical specifications (4.7 kOhms ±5%, 0.1W) and package format as the original part. The moisture-resistant feature provides enhanced environmental protection. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which may affect procurement and assembly processes. Full AEC-Q200 automotive compliance and ROHS3 certification are maintained. This part is suitable for direct functional replacement with packaging format accommodation.

AF0603JR-074K7L (YAGEO): This substitute maintains identical electrical specifications and adds anti-sulfur protection feature for enhanced reliability in corrosive environments. Explicit AEC-Q200 automotive rating is specified. Tape & Reel packaging matches the original format. ROHS3 compliance and operating temperature range are identical. Selection is appropriate for applications requiring sulfur corrosion resistance in addition to standard automotive qualification.

RC0603JR-074K7L (YAGEO): This substitute maintains identical electrical specifications (4.7 kOhms ±5%, 0.1W) with moisture-resistant feature. Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel). Automotive AEC-Q200 rating is not explicitly specified for this part number, which represents a deviation from the original specification. ROHS3 compliance and operating temperature range are maintained. Selection requires confirmation of automotive qualification requirements for the application.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF4701 be used as a direct replacement for RPC0603JT4K70?

A: Yes. ESR03EZPF4701 is a functional upgrade with tighter tolerance (±1% versus ±5%) and higher power rating (0.25W versus 0.1W). Both improvements are backward compatible. All critical parameters including resistance value, package size, operating temperature range, temperature coefficient, and AEC-Q200 automotive rating are identical. The upgrade provides enhanced performance margin without circuit redesign.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging supplies components on cut tape segments with optional reel format, suitable for lower-volume or mixed-component assembly. Both formats contain identical components; the difference is in supply and handling logistics. Verify assembly equipment compatibility before selecting packaging format.

Q: Why does RC0603JR-074K7L not specify AEC-Q200 rating?

A: RC0603JR-074K7L is listed with moisture-resistant feature but without explicit AEC-Q200 automotive qualification in the provided specification. This represents a specification gap rather than a performance deficiency. Confirmation of automotive qualification status is required before selection for applications mandating AEC-Q200 compliance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (ESR03EZPF4701, AC0603JR-074K7L, AF0603JR-074K7L, RC0603JR-074K7L) maintain ROHS3 compliance identical to the original RPC0603JT4K70. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences affect component value distribution within specified limits. RPC0603JT4K70 specifies ±5% tolerance (4.465 kOhms to 4.935 kOhms). ESR03EZPF4701 specifies ±1% tolerance (4.653 kOhms to 4.747 kOhms). Tighter tolerance reduces value variation and improves circuit predictability. Circuit design must account for the tolerance range of the selected component; tighter tolerance is always acceptable as a substitute.

Q: What is the significance of anti-sulfur protection in AF0603JR-074K7L?

A: Anti-sulfur protection prevents sulfur-induced corrosion of component terminations and internal elements, extending component life in environments with sulfur exposure (industrial, coastal, or high-pollution areas). This feature is beneficial for long-term reliability but is not required for standard applications. Selection depends on environmental exposure conditions of the application.
