Key Parameters

Substitute Part Grouping Explanation

Substitution logic is based on strict electrical and mechanical parameter matching:

Primary Matching Criteria:

• Resistance value: 2.4 MOhms (exact match required)
• Power rating: 0.25W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)

Tolerance Consideration: The main part RCS3216J245CS operates at ±5% tolerance. Substitute parts with ±1% tolerance are electrically compatible and represent improved accuracy. Parts with ±5% tolerance provide direct equivalence.

Compliance Alignment: All identified substitutes maintain ROHS3 compliance and MSL 1 rating. Additional certifications (AEC-Q200 automotive qualification, high voltage capability) represent enhanced specifications without compromising base functionality.

Packaging Format: The main part uses standard packaging. Substitute parts are available in Tape & Reel (TR) format, which is compatible for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalence (±5% Tolerance Match): RC1206JR-072M4L from YAGEO provides direct electrical equivalence to RCS3216J245CS with identical ±5% tolerance specification. Both parts maintain the same operating temperature range, temperature coefficient, and thick film composition. This substitute is suitable for applications where tolerance specification is a primary requirement.

Enhanced Accuracy Substitutes (±1% Tolerance): CRCW12062M40FKEA (Vishay Dale), KTR18EZPF2404 (Rohm Semiconductor), and RC1206FR-072M4L (YAGEO) all provide ±1% tolerance, representing improved accuracy over the main part. These substitutes are electrically compatible and maintain all core electrical and thermal specifications. Selection among these three depends on application-specific requirements:

• CRCW12062M40FKEA includes AEC-Q200 automotive qualification
• KTR18EZPF2404 includes AEC-Q200 automotive qualification and high voltage capability
• RC1206FR-072M4L includes moisture-resistant features aligned with the main part

All substitute parts are Active status and ROHS3 compliant, ensuring regulatory compliance equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-072M4L replace RCS3216J245CS in any application?

A: RC1206JR-072M4L is a direct substitute. Both parts share identical resistance (2.4 MOhms), tolerance (±5%), power rating (0.25W), package (1206), composition (thick film), operating temperature range (-55°C ~ 155°C), and temperature coefficient (±100ppm/°C). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between the ±5% and ±1% tolerance substitutes?

A: The main part RCS3216J245CS operates at ±5% tolerance. Substitute parts with ±1% tolerance (CRCW12062M40FKEA, KTR18EZPF2404, RC1206FR-072M4L) provide tighter resistance accuracy. Both tolerance classes are electrically compatible; selection depends on circuit accuracy requirements. Applications requiring tighter tolerance specifications benefit from ±1% alternatives.

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

A: The main part uses standard packaging. All identified substitutes are available in Tape & Reel (TR) format, which is compatible with automated assembly processes. TR packaging is standard for high-volume production environments.

Q: Do the substitute parts meet the same environmental compliance standards?

A: All substitute parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level) rating, matching the main part's compliance profile. Additional certifications (AEC-Q200 automotive qualification on CRCW12062M40FKEA and KTR18EZPF2404) represent enhanced specifications without reducing base compliance.

Q: Which substitute should be selected for automotive applications?

A: CRCW12062M40FKEA and KTR18EZPF2404 both carry AEC-Q200 automotive qualification. KTR18EZPF2404 additionally features high voltage capability. Selection between these two depends on specific circuit voltage requirements and supplier availability.

Q: Are the physical dimensions of substitute parts identical to the main part?

A: All parts use the 1206 (3216 Metric) package with identical PCB footprint. Length and width dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) for RCS3216J245CS, CRCW12062M40FKEA, and KTR18EZPF2404. YAGEO parts (RC1206FR-072M4L and RC1206JR-072M4L) have slightly different length at 0.122" L (3.10mm) but maintain identical width and are mechanically compatible with standard 1206 footprints. Height variations are within acceptable limits for PCB assembly.
