Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1540CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 154 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 0.248" L x 0.126" W footprint

Environmental & Compliance Parameters:

• Composition: Thick Film
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance
• REACH Unaffected status

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RC6432F1540CS in applications requiring 154 Ohm 1W 2512 chip resistors.

Parameter Comparison

Engineering Selection Recommendations

All three components—RC6432F1540CS, CRCW2512154RFKEG, and RMCF2512FT154R—are Active status products with identical electrical and mechanical specifications. Selection between these parts is based on:

Availability: CRCW2512154RFKEG (Vishay Dale) offers the highest inventory at 18,784 pieces. RMCF2512FT154R (Stackpole Electronics) provides 8,790 pieces. RC6432F1540CS (Samsung) has 900 pieces available.

Compliance Certifications: CRCW2512154RFKEG and RMCF2512FT154R both carry AEC-Q200 automotive qualification ratings, in addition to ROHS3 and REACH compliance. RC6432F1540CS meets ROHS3 and REACH requirements without automotive qualification designation.

Packaging: RC6432F1540CS and RMCF2512FT154R are supplied in standard packaging. CRCW2512154RFKEG is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Physical Dimensions: RC6432F1540CS and RMCF2512FT154R share identical length and width (0.248" L x 0.126" W). CRCW2512154RFKEG has a width of 0.124" W, representing a 0.002" reduction. Height specifications are 0.026" (RC6432F1540CS) versus 0.028" (both substitute parts), a 0.002" difference within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512154RFKEG directly replace RC6432F1540CS in all applications?

A: Yes. Both components share identical electrical parameters (154 Ohms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and package designation (2512). The 0.002" width difference and 0.002" height difference are within standard PCB design tolerances and do not affect electrical performance or mechanical fit in standard 2512 footprints.

Q: What is the difference between the substitute parts?

A: CRCW2512154RFKEG (Vishay Dale) and RMCF2512FT154R (Stackpole Electronics) are both AEC-Q200 qualified automotive-grade resistors. RC6432F1540CS (Samsung) does not carry automotive qualification. All three meet ROHS3 and REACH compliance. Electrical and thermal specifications are identical across all three parts.

Q: Does packaging format affect substitution?

A: Packaging format (standard versus Tape & Reel) affects supply chain logistics and automated assembly compatibility but does not affect electrical or mechanical substitution. CRCW2512154RFKEG in Tape & Reel format is optimized for high-volume automated placement. Standard packaging is suitable for manual or lower-volume assembly.

Q: Are there dimensional concerns with substitution?

A: Physical dimensions are within standard PCB assembly tolerances. RC6432F1540CS and RMCF2512FT154R are identical in length and width (0.248" x 0.126"). CRCW2512154RFKEG width is 0.124" (0.002" narrower). Height differences range from 0.026" to 0.028" (0.002" maximum). These variations do not affect PCB footprint compatibility or solder joint reliability.

Q: Which substitute part should be selected for automotive applications?

A: CRCW2512154RFKEG and RMCF2512FT154R both carry AEC-Q200 automotive qualification. RC6432F1540CS does not have automotive certification. For automotive applications requiring AEC-Q200 compliance, select either CRCW2512154RFKEG or RMCF2512FT154R based on availability and packaging requirements.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All three parts carry MSL 1 rating, eliminating moisture-related storage or handling restrictions.
