RCS3216F434CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F434CS is a 430 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching electrical specifications, package dimensions, and environmental ratings to ensure direct functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F434CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 430 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match or wider)

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

All four substitute parts listed meet these core substitution criteria. Variations in physical dimensions (length, width, height) within standard 1206 tolerances and differences in feature sets (such as automotive AEC-Q200 certification) do not prevent substitution but may introduce additional capabilities or constraints depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production): The AC1206FR-07430KL (YAGEO), CRCW1206430KFKEA (Vishay Dale), and RC1206FR-07430KL (YAGEO) are all suitable direct substitutes for the RCS3216F434CS. All three maintain active product status and full ROHS3 compliance. The AC1206FR-07430KL and CRCW1206430KFKEA include automotive AEC-Q200 certification, providing additional qualification for automotive applications. The RC1206FR-07430KL offers standard industrial-grade performance without automotive-specific qualification.

Secondary Selection (Legacy Status): The ERJ-8ENF4303V (Panasonic) meets all electrical and mechanical substitution criteria and carries AEC-Q200 automotive certification. However, this part is designated "Not For New Designs," indicating it is in end-of-life status. Selection of this part should be limited to legacy system maintenance or where existing supply chain commitments exist.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes and storage conditions. REACH status is unaffected for all parts, and ECCN classification remains EAR99 across all options.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07430KL be used as a direct replacement for RCS3216F434CS?

A: Yes. Both parts share identical electrical specifications (430 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), identical package type (1206 / 3216 Metric), and equivalent compliance ratings (ROHS3, MSL 1). Physical dimensions vary slightly within standard 1206 tolerances and do not affect PCB layout compatibility.

Q: What is the difference between AC1206FR-07430KL and RC1206FR-07430KL?

A: Both are YAGEO 430 kOhms ±1% 1206 resistors with identical electrical performance. AC1206FR-07430KL includes automotive AEC-Q200 certification and is designated for automotive applications. RC1206FR-07430KL is standard industrial-grade without automotive qualification. Selection depends on application requirements.

Q: Why is ERJ-8ENF4303V marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life status and Panasonic is not recommending it for new circuit designs. Existing inventory may remain available, but long-term supply cannot be guaranteed. For new designs, select from AC1206FR-07430KL, CRCW1206430KFKEA, or RC1206FR-07430KL.

Q: Are there dimensional differences between these substitute parts?

A: Minor dimensional variations exist within standard 1206 package tolerances. Length ranges from 3.10mm to 3.20mm, width is consistently 1.60mm, and height ranges from 0.60mm to 0.70mm. These variations are within PCB design tolerances and do not affect electrical performance or mechanical fit in standard 1206 footprints.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard dry storage and handling procedures apply equally to all parts.

Q: Which substitute part offers the best availability?

A: ERJ-8ENF4303V (Panasonic) shows the highest inventory level at 50,108 pieces. However, given its "Not For New Designs" status, CRCW1206430KFKEA (Vishay Dale) with 15,863 pieces or RC1206FR-07430KL (YAGEO) with 42,399 pieces are preferred for active projects.
