Substitute Part Grouping Explanation

Substitute parts for the RCS3216F165CS are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

Resistance value: 1.6 MOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical for Substitution):

Package type: 1206 (3216 Metric)
Number of terminations: 2

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

KTR18EZPF1604 (Rohm Semiconductor) and RC1206FR-071M6L (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and supply chain stability. KTR18EZPF1604 includes automotive AEC-Q200 certification and high voltage capability, providing enhanced specifications for demanding applications. RC1206FR-071M6L offers moisture-resistant properties aligned with the original part's environmental protection features.

Secondary Substitute (Legacy Status):

ERJ-8ENF1604V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part is suitable for replacement in existing applications or legacy system maintenance but should not be selected for new circuit designs due to potential future availability constraints.

Compliance Alignment:

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, ensuring regulatory compatibility across industrial, commercial, and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can KTR18EZPF1604 replace RCS3216F165CS in all applications?

A: Yes. KTR18EZPF1604 meets all electrical and mechanical specifications of RCS3216F165CS. The additional AEC-Q200 automotive certification and high voltage capability represent enhanced features that do not restrict substitution. The maximum seated height difference (0.65mm vs. 0.66mm) is negligible for standard PCB assembly.

Q: Why is ERJ-8ENF1604V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and marketing of this part. While electrically and mechanically equivalent, it should not be specified for new circuit designs due to potential supply discontinuation. It remains suitable for replacement in existing systems.

Q: Are there dimensional compatibility concerns between substitute parts?

A: All substitute parts use the 1206 (3216 Metric) package with identical length (0.126" / 3.20mm) and width (0.063" / 1.60mm). Seated height variations range from 0.65mm to 0.70mm, which fall within standard PCB assembly tolerances and do not affect footprint compatibility.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: This specification indicates identical temperature stability performance. All parts exhibit the same resistance drift rate across the -55°C to 155°C operating range, ensuring equivalent circuit behavior in temperature-sensitive applications.

Q: Does packaging format (Tape & Reel vs. bulk) affect electrical performance?

A: No. Packaging format affects only logistics and handling. RCS3216F165CS and all substitute parts are electrically identical regardless of whether supplied in Tape & Reel (TR) or alternative packaging configurations.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RCS3216F165CS and all identified substitutes carry ROHS3 Compliant status, meeting environmental and regulatory requirements for EU and global markets.
