Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4643CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 464 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package type: 0805 (2012 Metric) (exact match)
• Composition: Thick Film (exact match)
• Physical dimensions: 0.079" L x 0.049" W / 2.00mm x 1.25mm (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level MSL 1
• REACH Unaffected status

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F4643CS in standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805464KFKEA replace RCS2012F4643CS directly on the PCB?

A: Yes. Both components share identical electrical specifications (464 kOhms ±1%, 0.125W), composition (thick film), package type (0805), and operating temperature range (-55°C ~ 155°C). Physical dimensions are equivalent at 2.00mm x 1.25mm. Height variation (0.50mm vs 0.66mm) does not affect PCB assembly compatibility.

Q: What is the difference between the substitute parts?

A: All substitute parts meet the same electrical and mechanical requirements. Differences exist in manufacturer certifications: CRCW0805464KFKEA, ERJ-6ENF4643V, and KTR10EZPF4643 include AEC-Q200 automotive qualification. KTR10EZPF4643 adds high voltage capability. RCS2012F4643CS and RC0805FR-07464KL emphasize moisture-resistant features. These distinctions do not affect electrical interchangeability in standard applications.

Q: Are height variations between parts significant?

A: Height variations range from 0.50mm to 0.70mm across all parts. These differences fall within standard PCB assembly tolerances and do not impact component placement, soldering, or electrical performance in 0805 package applications.

Q: Do all parts meet the same compliance standards?

A: Yes. All five components are ROHS3 compliant, carry MSL 1 rating (unlimited moisture sensitivity), and maintain REACH Unaffected status. They are suitable for equivalent use in regulated applications.

Q: Which substitute offers the best availability?

A: ERJ-6ENF4643V (Panasonic) offers the highest inventory at 1,572,228 pieces. RC0805FR-07464KL (YAGEO) provides 43,413 pieces. Both represent strong supply chain options for high-volume requirements.

Q: Can I use KTR10EZPF4643 in place of RCS2012F4643CS in non-automotive applications?

A: Yes. KTR10EZPF4643 meets all electrical and mechanical specifications of RCS2012F4643CS. The AEC-Q200 automotive qualification and high voltage capability are additional features that do not restrict use in standard industrial or commercial circuits.
