RC1608F1620CS Equivalent & Substitute Parts Reference

Part Overview

The RC1608F1620CS is a 162 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0603 (1608 Metric) package format with 0.1W power rating. This component is classified as Active product status with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1). The part is RoHS3 compliant and REACH unaffected, suitable for industrial and commercial applications requiring stable resistance values across the -55°C to 155°C operating temperature range.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F1620CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 162 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed below meet these mandatory parameters. Substitute parts are grouped by product status and additional features:

Direct Equivalents (Active Status, Standard Features): CR0603-FX-1620ELF (Bourns Inc.), RC0603FR-07162RL (YAGEO)

Upgrade Classification (Discontinued Status): MCR03ERTF1620 (Rohm Semiconductor) - available but discontinued at distributor level

Enhanced Variants (Active Status, Automotive AEC-Q200 Rated): CRCW0603162RFKEA (Vishay Dale), ERJ-3EKF1620V (Panasonic Electronic Components), RMCF0603FT162R (Stackpole Electronics Inc)

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0603-FX-1620ELF (Bourns Inc.) and RC0603FR-07162RL (YAGEO) are direct functional equivalents with Active product status. Both maintain identical electrical specifications and moisture-resistant construction. Selection between these options depends on supply availability and procurement lead times.

For Automotive and High-Reliability Applications: CRCW0603162RFKEA (Vishay Dale), ERJ-3EKF1620V (Panasonic Electronic Components), and RMCF0603FT162R (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards. These parts are suitable for applications requiring automotive-grade component certification while maintaining all electrical and thermal specifications of the primary part.

For Legacy System Support: MCR03ERTF1620 (Rohm Semiconductor) is available in limited inventory but carries Discontinued status at distributor level. This part meets all electrical and compliance requirements but should be used only when supply chain constraints prevent access to Active-status alternatives.

All substitute parts are RoHS3 compliant, MSL 1 rated, and operate across the identical -55°C to 155°C temperature range with ±100ppm/°C temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-1620ELF replace RC1608F1620CS in existing designs without modification?

A: Yes. CR0603-FX-1620ELF meets all mandatory electrical parameters (162 Ω ±1%, 0.1W, ±100ppm/°C) and package specifications (0603 1608 Metric). Both parts are RoHS3 compliant with MSL 1 rating. No circuit redesign or PCB layout modification is required.

Q: What is the difference between standard and AEC-Q200 rated variants?

A: AEC-Q200 rated parts (CRCW0603162RFKEA, ERJ-3EKF1620V, RMCF0603FT162R) carry automotive qualification certification. Electrically and mechanically, they are identical to standard variants. AEC-Q200 qualification is required only for automotive applications; standard industrial applications do not require this certification.

Q: Are there dimensional differences between substitute parts?

A: Dimensional variations exist within tolerance. The RC1608F1620CS specifies 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height. CRCW0603162RFKEA specifies 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height. These variations remain within 0603 package class tolerances and do not affect PCB assembly or electrical performance.

Q: Why is MCR03ERTF1620 marked as Discontinued?

A: MCR03ERTF1620 is discontinued at DiGi Electronics distributor level but remains electrically and mechanically equivalent. Discontinued status indicates reduced availability through primary distribution channels. Use this part only when supply of Active-status alternatives is exhausted.

Q: Can automotive-rated parts be used in non-automotive applications?

A: Yes. AEC-Q200 rated parts exceed standard industrial requirements and are fully compatible with non-automotive designs. Using automotive-qualified components in standard applications introduces no technical risk and may improve long-term reliability.

Q: What packaging formats are available for these substitute parts?

A: All listed substitute parts are available in Tape & Reel (TR) format suitable for automated assembly. MCR03ERTF1620 is also available in Cut Tape (CT) and Digi-Reel format. Packaging selection depends on production volume and assembly equipment compatibility.
