Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F1622CS are qualified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Resistance value: 16.2 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package designation: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 2512 footprint

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

Two substitute parts meet all criteria: CRCW251216K2FKEG (Vishay Dale) and RMCF2512FT16K2 (Stackpole Electronics Inc). Both maintain identical electrical specifications and package compatibility while offering additional automotive AEC-Q200 qualification. Packaging format differs (Tape & Reel versus Cut Tape), allowing selection based on assembly process requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full ROHS3 compliance with REACH Unaffected designation, confirming regulatory alignment for current and future applications.

RC6432F1622CS (Samsung Electro-Mechanics): Primary specification with moisture-resistant thick film construction. Suitable for standard industrial applications requiring the specified electrical and thermal characteristics.

CRCW251216K2FKEG (Vishay Dale): Substitute with automotive AEC-Q200 qualification. Tape & Reel packaging format supports high-volume automated assembly processes. Dimensions vary slightly in width (3.15mm versus 3.20mm) and seated height (0.70mm versus 0.66mm), remaining within 2512 package tolerance. Higher inventory availability (4287 units) supports supply chain continuity.

RMCF2512FT16K2 (Stackpole Electronics Inc): Substitute with automotive AEC-Q200 qualification. Cut Tape packaging format accommodates manual or semi-automated assembly workflows. Dimensions match the original part precisely (6.30mm x 3.20mm length and width). Highest inventory availability (8952 units) provides extended supply security. Series designation RMCF confirms Stackpole thick film resistor lineage.

Selection between substitute parts depends on assembly methodology and supply chain requirements rather than electrical performance, as all three components deliver identical functional specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW251216K2FKEG replace RC6432F1622CS directly on the PCB?

A: Yes. Both parts share identical electrical specifications (16.2 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and the same 2512 package footprint. Dimensional variations (width 3.15mm versus 3.20mm, height 0.70mm versus 0.66mm) fall within standard 2512 package tolerances and do not affect PCB placement or soldering.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (CRCW251216K2FKEG) supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (RMCF2512FT16K2) provides components on tape segments, suitable for lower-volume production or manual assembly workflows. Both formats contain identical components; packaging selection depends on assembly equipment and production volume.

Q: Does the automotive AEC-Q200 qualification on substitute parts affect non-automotive applications?

A: No. AEC-Q200 qualification represents additional testing and quality assurance beyond standard specifications. Components meeting AEC-Q200 are fully compatible with non-automotive applications and provide equivalent or superior reliability characteristics.

Q: Are the dimensional differences between substitute parts significant?

A: No. The width variation (3.15mm versus 3.20mm) and height variation (0.66mm versus 0.70mm) are within standard 2512 package tolerances. All three parts mount identically on 2512 footprints without design modification.

Q: Can I mix different substitute parts in the same assembly?

A: Yes. All three parts deliver identical electrical performance and package compatibility. Mixed sourcing is permissible when supply constraints require component substitution during production.

Q: What compliance certifications apply to all three parts?

A: All parts are ROHS3 Compliant, REACH Unaffected, and carry EAR99 ECCN classification with HTSUS code 8533.21.0030. Moisture Sensitivity Level 1 (Unlimited) applies to all three, indicating no moisture precautions required during storage or handling.
