Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F115CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 1.1 MOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) within standard tolerances and differences in optional features (such as automotive AEC-Q200 certification or high voltage capability) do not preclude substitution, as these represent enhanced or application-specific characteristics rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

AC1206FR-071M1L (YAGEO), CRCW12061M10FKEA (Vishay Dale), KTR18EZPF1104 (Rohm Semiconductor), and RC1206FR-071M1L (YAGEO) are all suitable direct replacements with Active product status. These parts maintain full electrical and mechanical compatibility with the RCS3216F115CS. Selection among these options may be based on supply chain availability, packaging format (Tape & Reel), or application-specific requirements such as automotive qualification (AEC-Q200) or high voltage capability.

Conditional Substitute (Legacy Status):

ERJ-8ENF1104V (Panasonic Electronic Components) meets all electrical and mechanical specifications but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or maintenance scenarios but should not be selected for new circuit designs.

Compliance Considerations:

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory compliance profile of the RCS3216F115CS. No additional qualification or testing is required based on compliance certifications alone.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-071M1L replace RCS3216F115CS in all applications?

A: Yes. AC1206FR-071M1L meets all mandatory electrical parameters (1.1 MOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package specifications (1206). The addition of automotive AEC-Q200 certification represents enhanced qualification, not a limitation. Physical dimensions vary slightly (3.10mm vs 3.20mm length, 0.65mm vs 0.66mm height) within standard tolerances and do not affect circuit compatibility.

Q: What is the difference between parts with and without AEC-Q200 certification?

A: AEC-Q200 certification indicates automotive-grade qualification with enhanced reliability testing and traceability. Parts with this certification (AC1206FR-071M1L, CRCW12061M10FKEA, ERJ-8ENF1104V, KTR18EZPF1104) are suitable for automotive applications. Parts without this certification (RCS3216F115CS, RC1206FR-071M1L) are functionally equivalent but lack automotive-specific qualification. Selection depends on application requirements, not electrical performance.

Q: Why is ERJ-8ENF1104V marked "Not For New Designs"?

A: This status indicates the manufacturer has discontinued active development and recommends alternative parts for new circuit designs. However, the part remains functionally equivalent and suitable for replacement in existing applications or maintenance. For new designs, AC1206FR-071M1L, CRCW12061M10FKEA, KTR18EZPF1104, or RC1206FR-071M1L are preferred.

Q: Are there any package compatibility issues between these substitutes?

A: All parts use the 1206 (3216 Metric) package with 2 terminations. Physical dimensions vary within standard tolerances: length ranges from 3.10mm to 3.20mm, width is 1.60mm, and height ranges from 0.60mm to 0.70mm. These variations are within PCB design tolerances and do not affect mechanical fit or electrical performance.

Q: What is the significance of the "High Voltage" feature in KTR18EZPF1104?

A: The high voltage capability of KTR18EZPF1104 represents an enhanced feature beyond the base specifications. This part is suitable for applications requiring higher voltage stress tolerance. However, this feature does not preclude its use in standard applications; it simply provides additional margin. Selection should be based on circuit voltage requirements.

Q: Can I mix different substitute parts in the same circuit?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers or part numbers in the same circuit is acceptable from a functional standpoint. However, for manufacturing consistency and traceability, using a single part number across a design is recommended.
