Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F1623CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters: Resistance value (162 kOhms), tolerance (±1%), power rating (0.1W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Parameters: Package format (0603 / 1608 Metric), physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and maximum seated height (0.022" / 0.55mm) ensure PCB footprint compatibility.

Material & Construction: Thick film composition and moisture-resistant features maintain performance characteristics across the operating temperature range (-55°C to 155°C).

Compliance & Certifications: RoHS3 compliance and MSL Level 1 rating are required for environmental and reliability standards. Automotive AEC-Q200 certification is an additional qualification available in certain substitute options but is not mandatory for general-purpose applications.

Packaging Format: Tape & Reel (TR) is the primary packaging specification; Cut Tape (CT) variants are functionally equivalent but differ in supply format.

Substitutes are categorized as Direct Equivalents (identical specifications and features) or Similar Parts (matching core electrical and mechanical parameters with additional certifications such as AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (General-Purpose Applications):

The CR0603-FX-1623ELF (Bourns Inc.) and RC0603FR-07162KL (YAGEO) are direct functional equivalents to the RC1608F1623CS. Both parts match all electrical specifications, mechanical dimensions, operating temperature range, and compliance requirements. These options are suitable for applications where automotive qualification is not required.

Automotive-Qualified Alternatives (AEC-Q200):

For applications requiring automotive-grade reliability, the following parts provide AEC-Q200 certification in addition to matching all core specifications:

AC0603FR-07162KL (YAGEO), CRCW0603162KFKEA (Vishay Dale), CRCW0603162KFKTA (Vishay Dale), ERJ-3EKF1623V (Panasonic Electronic Components), RMCF0603FG162K (Stackpole Electronics Inc), and RMCF0603FT162K (Stackpole Electronics Inc).

Packaging Considerations:

Tape & Reel (TR) packaging is standard for high-volume production. Cut Tape (CT) variants (CRCW0603162KFKTA, RMCF0603FG162K) are functionally identical but supplied in alternative formats suitable for lower-volume or mixed-component orders.

Product Status & Availability:

All listed substitute parts maintain Active product status, ensuring continued availability and manufacturing support. Inventory levels vary by manufacturer and distributor; RMCF0603FT162K (Stackpole) shows the highest inventory availability at 265,229 pieces.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC1608F1623CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts match the critical electrical parameters (162 kOhms ±1%, 0.1W, ±100ppm/°C) and mechanical specifications (0603 package, -55°C to 155°C operating range). Direct PCB footprint compatibility is maintained. No circuit redesign is required.

Q: What is the difference between Direct Equivalents and Similar Parts with AEC-Q200?

A: Direct equivalents (CR0603-FX-1623ELF, RC0603FR-07162KL) provide identical specifications without automotive certification. Similar parts with AEC-Q200 certification (AC0603FR-07162KL, CRCW0603162KFKEA, ERJ-3EKF1623V, RMCF0603FT162K) include additional automotive-grade reliability testing and qualification. Use AEC-Q200 parts only if your application requires automotive compliance.

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

A: No. Packaging format affects supply and handling only. Tape & Reel (TR) is optimized for automated assembly lines. Cut Tape (CT) is suitable for manual assembly or mixed-component orders. Electrical and mechanical performance is identical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the RC1608F1623CS compliance profile.

Q: Which substitute part has the highest inventory availability?

A: RMCF0603FT162K (Stackpole Electronics Inc) shows 265,229 pieces in stock, the highest among all listed substitutes. This part is Tape & Reel packaged with AEC-Q200 certification.

Q: Can I use a substitute part with AEC-Q200 certification in a non-automotive application?

A: Yes. AEC-Q200 certification represents additional qualification beyond standard specifications. Parts with AEC-Q200 are fully compatible with general-purpose applications and provide enhanced reliability margins.

Q: What is MSL Level 1, and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates Unlimited shelf life without moisture-related degradation. All listed parts carry MSL 1, meaning they do not require special dry-pack storage or baking procedures before soldering, simplifying inventory management and assembly processes.
