RC3216F1623CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F1623CS is a 162 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film, moisture-resistant resistor operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 730 pieces available in inventory.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental performance characteristics. Alternative sources provide equivalent functionality for applications requiring component substitution due to supply constraints, design flexibility, or specific manufacturing certifications.

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (162 kOhms), tolerance (±1%), and power dissipation rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) ensures physical fit and PCB footprint compatibility. Physical dimensions and height specifications confirm mounting surface compatibility.

Environmental & Compliance: ROHS3 compliance, MSL 1 rating, and REACH unaffected status are mandatory for equivalent substitution. Composition (thick film) and moisture resistance characteristics must be maintained.

Substitution Categories:

Direct Equivalents: Parts meeting all electrical, mechanical, and compliance parameters with identical feature sets (moisture resistant, standard industrial grade)
Similar Equivalents: Parts meeting all core electrical and mechanical parameters but with enhanced certifications (Automotive AEC-Q200 rated) or different product lifecycle status

All identified substitutes maintain the 1206 package footprint, 162 kOhms resistance, ±1% tolerance, 0.25W power rating, and -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC3216F1623CS with CR1206-FX-1623ELF in my design?

A: Yes. Both parts share identical electrical specifications (162 kOhms ±1%, 0.25W), operate across -55°C to 155°C, use 1206 package footprint, and maintain ROHS3 compliance with MSL 1 rating. Physical dimensions are equivalent for PCB mounting.

Q: What is the difference between the standard moisture-resistant versions and the AEC-Q200 automotive versions?

A: The standard versions (RC3216F1623CS, CR1206-FX-1623ELF, RC1206FR-07162KL) are industrial-grade thick film resistors with moisture resistance. The AEC-Q200 versions (CRCW1206162KFKEA, ERJ-8ENF1623V, RMCF1206FT162K) carry automotive qualification certification, indicating enhanced reliability testing and qualification for automotive applications. Electrical performance and package compatibility remain identical.

Q: Are all these parts physically interchangeable on the PCB?

A: All identified substitutes use the 1206 (3216 Metric) package designation. Physical dimensions are nominally equivalent (0.126" L x 0.063" W / 3.20mm x 1.60mm). Height specifications vary slightly (0.024" to 0.030" / 0.60mm to 0.75mm seated height), but these variations fall within standard PCB assembly tolerances and do not affect interchangeability.

Q: Why is ERJ-8ENF1623V marked "Not For New Designs"?

A: "Not For New Designs" indicates the part is in end-of-life or legacy status at the manufacturer. Panasonic continues to supply existing inventory but does not recommend this part for new product development. Use this part only for sustaining production of existing designs or replacement applications.

Q: Do all substitutes maintain the same temperature coefficient?

A: Yes. All identified substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring equivalent thermal performance across the specified operating envelope.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-07162KL (YAGEO) provides the highest inventory stock at 184,199 pieces, followed by ERJ-8ENF1623V (Panasonic) at 95,952 pieces. For immediate availability with active product status, RC1206FR-07162KL is the optimal choice.

Q: Are these parts suitable for high-reliability applications?

A: All identified substitutes are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating. For automotive or high-reliability applications, select AEC-Q200 certified versions: CRCW1206162KFKEA, ERJ-8ENF1623V, or RMCF1206FT162K.
