Substitute Part Grouping Explanation

Substitute parts for the RC1608F2801CS are classified based on substitution relationship type and feature alignment:

Substitution Logic: All substitute parts maintain identical electrical specifications: 2.8 kOhms resistance, ±1% tolerance, 0.1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. All parts use thick film composition, feature 0603 (1608 Metric) package format with 2 terminations, and comply with RoHS3 and REACH requirements.

Direct Substitutes (Functionally Equivalent): Parts classified as direct substitutes share all core electrical and mechanical parameters with the main part. These include CR0603-FX-2801ELF (Bourns Inc.) and RC0603FR-072K8L (YAGEO). Both maintain standard moisture-resistant construction and MSL 1 rating.

Upgrade Classification: MCR03ERTF2801 (Rohm Semiconductor) is listed as upgrade status with discontinued availability at DiGi Electronics. This part maintains all electrical and mechanical specifications but features discontinuation status.

Similar Parts with Enhanced Features: AC0603FR-072K8L (YAGEO), CRCW06032K80FKEA (Vishay Dale), ERJ-3EKF2801V (Panasonic Electronic Components), and RMCF0603FT2K80 (Stackpole Electronics Inc.) are classified as similar parts. These components add Automotive AEC-Q200 qualification to the base specification, making them suitable for automotive applications while maintaining all standard parameters.

Key Parameters Determining Substitutability:

• Resistance value: 2.8 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature: -55°C ~ 155°C (exact match required)

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0603-FX-2801ELF (Bourns Inc.) and RC0603FR-072K8L (YAGEO) are direct functional equivalents to RC1608F2801CS. Both parts maintain identical electrical and mechanical specifications with Active product status and standard moisture-resistant construction. Selection between these options is based on supply availability and procurement lead times.

For Automotive Applications: AC0603FR-072K8L (YAGEO), CRCW06032K80FKEA (Vishay Dale), ERJ-3EKF2801V (Panasonic Electronic Components), and RMCF0603FT2K80 (Stackpole Electronics Inc.) are qualified for automotive use with AEC-Q200 certification. These parts maintain all base electrical specifications while adding automotive-grade reliability qualification. Selection among these options depends on automotive supply chain requirements and qualification documentation needs.

Regarding MCR03ERTF2801: This Rohm Semiconductor part is listed with discontinued status at DiGi Electronics. While electrical and mechanical parameters remain equivalent, the discontinued classification limits its suitability for new designs or long-term production requirements.

Compliance Considerations: All listed substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 rating identical to the main part. No additional compliance verification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-2801ELF replace RC1608F2801CS in existing designs?

A: Yes. CR0603-FX-2801ELF maintains identical electrical specifications (2.8 kOhms ±1%, 0.1W), package format (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both parts feature moisture-resistant construction and MSL 1 rating. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between standard and automotive-qualified parts in this list?

A: AC0603FR-072K8L, CRCW06032K80FKEA, ERJ-3EKF2801V, and RMCF0603FT2K80 include Automotive AEC-Q200 qualification. This certification indicates compliance with automotive reliability and quality standards. Standard parts (RC1608F2801CS, CR0603-FX-2801ELF, RC0603FR-072K8L) do not carry this automotive qualification. Selection depends on application requirements.

Q: Are there physical dimension differences between substitute parts?

A: Most parts maintain 0603 (1608 Metric) package with 0.063" L x 0.031" W (1.60mm x 0.80mm) dimensions and 0.022" (0.55mm) maximum seated height. CRCW06032K80FKEA and RMCF0603FT2K80 show minor dimensional variations: CRCW06032K80FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) height; RMCF0603FT2K80 measures 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations remain within 0603 package tolerance and do not affect PCB footprint compatibility.

Q: Why is MCR03ERTF2801 listed as discontinued?

A: MCR03ERTF2801 is marked discontinued at DiGi Electronics, indicating limited availability through primary distribution channels. While electrical and mechanical specifications remain equivalent, discontinued status restricts its use for new production designs requiring long-term supply assurance.

Q: Do all substitute parts meet the same environmental specifications?

A: Yes. All listed substitute parts maintain identical operating temperature range (-55°C to 155°C), temperature coefficient (±100ppm/°C), RoHS3 compliance, and MSL 1 rating. Environmental performance specifications are equivalent across all parts.

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

A: RC1608F2801CS is supplied in Tape & Reel (TR) format. CR0603-FX-2801ELF, AC0603FR-072K8L, CRCW06032K80FKEA, ERJ-3EKF2801V, and RMCF0603FT2K80 are supplied in Tape & Reel (TR) format. RC0603FR-072K8L and MCR03ERTF2801 are supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements and volume specifications.
