Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608J8R2CS are grouped based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Mandatory Matching Parameters:

• Resistance value: 8.2 Ohms (exact match required)
• Package / Case: 0603 (1608 Metric) (physical compatibility)
• Power Rating: 0.1W (1/10W) (electrical capacity)
• Composition: Thick Film (construction method)
• Operating Temperature Range: -55°C ~ 155°C (thermal compatibility)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (moisture handling)

Tolerance Variations: Substitutes are available in two tolerance grades: ±5% (direct equivalents) and ±1% (upgraded precision). Both tolerance grades are acceptable substitutes when circuit design permits tighter tolerance specifications.

Feature Differentiation: Some substitutes include automotive AEC-Q200 qualification and enhanced features (current sense, high voltage capability), which represent functional upgrades without compromising base electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (±5% Tolerance, Non-Automotive): RC0603JR-078R2L (YAGEO) serves as a direct functional equivalent to RC1608J8R2CS with identical tolerance specification and moisture-resistant construction. Both parts are RoHS3 compliant and MSL 1 rated. Selection between these two is based on procurement availability and supply chain requirements.

Upgraded Substitutes (±1% Tolerance, Automotive AEC-Q200): ERJ-3RQF8R2V (Panasonic), KTR03EZPF8R20 (Rohm), RMCF0603FT8R20 (Stackpole), and RMCF0603JT8R20 (Stackpole) represent functional upgrades with tighter tolerance specifications and automotive qualification. These parts are suitable for applications requiring enhanced precision and automotive-grade reliability. All maintain identical package, power rating, and operating temperature specifications.

Tolerance-Matched Selection:

• For ±5% tolerance requirement: RC0603JR-078R2L or RMCF0603JT8R20
• For ±1% tolerance requirement: ERJ-3RQF8R2V, KTR03EZPF8R20, or RMCF0603FT8R20

Compliance Considerations: All substitute parts maintain RoHS3 compliance and MSL 1 rating. Automotive applications requiring AEC-Q200 qualification must select from the qualified substitute list (ERJ-3RQF8R2V, KTR03EZPF8R20, RMCF0603FT8R20, RMCF0603JT8R20).

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608J8R2CS with a ±1% tolerance part? A: Yes. Parts with ±1% tolerance (ERJ-3RQF8R2V, KTR03EZPF8R20, RMCF0603FT8R20) are direct substitutes. Tighter tolerance represents improved precision and is functionally compatible with circuits designed for ±5% tolerance.

Q: Are all substitute parts in the same 0603 package? A: Yes. All listed substitutes use the 0603 (1608 Metric) package format with identical footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm), ensuring PCB compatibility.

Q: What is the difference between automotive AEC-Q200 and non-automotive versions? A: AEC-Q200 qualified parts (ERJ-3RQF8R2V, KTR03EZPF8R20, RMCF0603FT8R20, RMCF0603JT8R20) meet automotive industry reliability and qualification standards. Non-automotive versions (RC1608J8R2CS, RC0603JR-078R2L) are suitable for general-purpose applications. Selection depends on application requirements.

Q: Do all parts have the same temperature coefficient? A: No. RC1608J8R2CS has ±300ppm/°C, while all substitutes have ±200ppm/°C. The lower temperature coefficient in substitutes indicates better thermal stability across the -55°C to 155°C operating range.

Q: Is moisture sensitivity level the same across all parts? A: Yes. All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Can I use RMCF0603JT8R20 as a direct replacement for RC1608J8R2CS? A: Yes. RMCF0603JT8R20 matches the ±5% tolerance specification and maintains identical electrical and mechanical parameters. The addition of AEC-Q200 qualification is a functional enhancement that does not affect compatibility.

Q: What is the difference between ERJ-3RQF8R2V and KTR03EZPF8R20? A: Both are ±1% tolerance, AEC-Q200 qualified substitutes with identical electrical specifications. ERJ-3RQF8R2V includes current sense capability, while KTR03EZPF8R20 includes high voltage capability. Selection depends on specific application requirements.
