Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F1870CS is determined by strict equivalence across the following parameters: resistance value (187 Ohms), tolerance (±1%), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within acceptable tolerances and differences in packaging format (Tape & Reel versus Cut Tape) do not affect functional substitutability. Product status and specific feature sets (such as automotive AEC-Q200 qualification or anti-sulfur properties) are noted but do not disqualify substitution based on electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CRCW1206187RFKEA, ERJ-8ENF1870V, and RC1206FR-07187RL—satisfy the core electrical and mechanical requirements for direct substitution with RCS3216F1870CS. Selection among these alternatives should be based on the following criteria:

CRCW1206187RFKEA (Vishay Dale): This part is Active in product status and carries AEC-Q200 automotive qualification. It is suitable for applications requiring automotive-grade reliability. Inventory availability is 14,869 pieces. Packaging is Tape & Reel format.

ERJ-8ENF1870V (Panasonic Electronic Components): This part carries AEC-Q200 automotive qualification but is marked as Not For New Designs. It remains available with 15,578 pieces in inventory. Packaging is Cut Tape & Digi-Reel format. This part should be used only for legacy design support or replacement applications.

RC1206FR-07187RL (YAGEO): This part is Active in product status with the highest inventory availability at 44,195 pieces. It features moisture-resistant properties similar to the original RCS3216F1870CS. Packaging is Tape & Reel format. This option provides the best availability for high-volume procurement.

For new designs, CRCW1206187RFKEA or RC1206FR-07187RL are preferred. For legacy or automotive-specific applications, CRCW1206187RFKEA is recommended due to its Active status and AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206187RFKEA replace RCS3216F1870CS in all applications?

A: Yes. Both parts share identical electrical specifications (187 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), and are packaged in 1206 (3216 Metric) format. Physical dimensions are equivalent within acceptable tolerances. CRCW1206187RFKEA includes AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive and harsh-environment applications.

Q: What is the difference between the packaging formats (Tape & Reel vs. Cut Tape)?

A: Tape & Reel (TR) packaging is optimized for automated assembly processes and high-volume production. Cut Tape (CT) packaging is suitable for lower-volume applications or manual assembly. Both formats contain the same component and are electrically and mechanically equivalent. Selection depends on manufacturing process requirements, not component performance.

Q: Why is ERJ-8ENF1870V marked as "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While the component remains available and functionally equivalent, it is recommended for replacement or legacy support only. For new designs, CRCW1206187RFKEA or RC1206FR-07187RL are preferred alternatives.

Q: Are there dimensional differences that affect PCB layout?

A: Minor dimensional variations exist within acceptable tolerances. RC1206FR-07187RL has a length of 0.122" (3.10mm) compared to 0.126" (3.20mm) for other parts. Height variations range from 0.024" to 0.028". These differences are within standard 1206 package tolerances and do not require PCB layout modifications. All parts are mechanically interchangeable in standard 1206 footprints.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). All carry the same ECCN (EAR99) and HTSUS (8533.21.0030) classifications as the original RCS3216F1870CS.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-07187RL (YAGEO) provides the highest inventory with 44,195 pieces in stock, followed by ERJ-8ENF1870V (Panasonic) with 15,578 pieces, and CRCW1206187RFKEA (Vishay Dale) with 14,869 pieces. For high-volume or time-sensitive procurement, RC1206FR-07187RL is the optimal choice.
