Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• Resistance value: 5.6 Ohms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Power rating: 0.1W, 1/10W (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)
• RoHS Status: ROHS3 Compliant (minimum requirement)

Secondary Compatibility Criteria:

• Tolerance: ±5% or tighter (±1% is acceptable as upgrade)
• Temperature Coefficient: ±300ppm/°C or better (±200ppm/°C is acceptable as upgrade)
• Packaging: Tape & Reel (TR) format

All identified substitute parts maintain identical electrical performance within the specified operating envelope and are mechanically interchangeable in 0603 footprint applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (±5% Tolerance): RC0603JR-075R6L (YAGEO) and RMCF0603JT5R60 (Stackpole Electronics Inc) are direct functional equivalents with identical tolerance specifications. Both maintain ±5% tolerance matching the original RC1608J5R6CS specification. YAGEO RC0603JR-075R6L offers the highest inventory availability (280,163 pcs). RMCF0603JT5R60 includes automotive AEC-Q200 qualification for applications requiring enhanced reliability standards.

Upgraded Substitutes (±1% Tolerance): RMCF0603FT5R60 (Stackpole Electronics Inc), ERJ-3RQF5R6V (Panasonic Electronic Components), and KTR03EZPF5R60 (Rohm Semiconductor) provide tighter tolerance specifications at ±1%, representing performance upgrades. All three carry AEC-Q200 automotive qualification. ERJ-3RQF5R6V includes current sense capability. KTR03EZPF5R60 includes high voltage features. These parts are suitable for applications where improved tolerance performance is beneficial.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range (-55°C ~ 155°C). Selection should be based on application requirements, inventory availability, and specific feature requirements (automotive qualification, current sense, high voltage capability).

Frequently Asked Questions (FAQ)

Q: Can RC0603JR-075R6L replace RC1608J5R6CS directly? A: Yes. Both parts share identical resistance (5.6 Ω), tolerance (±5%), power rating (0.1W), package (0603), and operating temperature range (-55°C ~ 155°C). The RC0603JR-075R6L features improved temperature coefficient (±200ppm/°C vs ±300ppm/°C) and moisture-resistant construction, making it a direct functional equivalent.

Q: What is the difference between ±5% and ±1% tolerance substitutes? A: Tolerance defines the acceptable resistance variation from the nominal 5.6 Ω value. ±5% tolerance allows variation between 5.32 Ω and 5.88 Ω. ±1% tolerance restricts variation to 5.54 Ω and 5.66 Ω. Applications requiring tighter resistance control should specify ±1% parts (RMCF0603FT5R60, ERJ-3RQF5R6V, KTR03EZPF5R60).

Q: Are automotive-qualified parts (AEC-Q200) suitable for non-automotive applications? A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. These parts (RMCF0603JT5R60, RMCF0603FT5R60, ERJ-3RQF5R6V, KTR03EZPF5R60) are fully compatible with non-automotive applications and provide additional reliability assurance.

Q: What does MSL Level 1 mean? A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL Level 1 rating, eliminating moisture-related handling constraints.

Q: Can I use a substitute part with different physical dimensions? A: All substitute parts maintain 0603 (1608 Metric) package format with identical footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm). Physical interchangeability is guaranteed. Minor height variations (RMCF series at 0.061" L vs standard 0.063" L) do not affect PCB mounting compatibility.

Q: Which substitute offers the best inventory availability? A: RC0603JR-075R6L (YAGEO) provides the highest inventory level at 280,163 pcs, followed by RMCF0603FT5R60 (Stackpole) at 113,258 pcs and ERJ-3RQF5R6V (Panasonic) at 68,510 pcs.
