Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F48R7CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 48.7 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. bulk), and additional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution but represent secondary differentiators for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW120648R7FKEA (Vishay Dale) and RC1206FR-0748R7L (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturing support. CRCW120648R7FKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-0748R7L provides moisture-resistant construction aligned with the original part's environmental protection features.

Secondary Substitute (Legacy Status):

ERJ-8ENF48R7V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria and carries AEC-Q200 automotive certification. However, this part is designated "Not For New Designs," indicating Panasonic has discontinued active development. This part remains suitable for replacement in existing production runs or field service applications where inventory exists, but should not be selected for new circuit designs.

Selection Basis:

All substitutes are selected exclusively on the basis of parameter equivalence, compliance certifications (ROHS3, REACH Unaffected), and product lifecycle status. Packaging format differences (Tape & Reel versus bulk) reflect supply chain and manufacturing process variations and do not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW120648R7FKEA replace RCS3216F48R7CS in existing designs?

A: Yes. CRCW120648R7FKEA is electrically and mechanically equivalent across all critical parameters: 48.7 Ohm resistance, ±1% tolerance, 0.25W power rating, 1206 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. The primary difference is packaging format (Tape & Reel versus bulk) and the addition of AEC-Q200 automotive certification.

Q: What is the difference between the Samsung RCS3216F48R7CS and YAGEO RC1206FR-0748R7L?

A: Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. Physical dimensions vary slightly within 1206 package tolerance: Samsung height is 0.66mm maximum, YAGEO is 0.65mm maximum. Samsung emphasizes anti-sulfur protection; YAGEO emphasizes moisture resistance. Both are ROHS3 compliant with MSL 1 rating. YAGEO is supplied in Tape & Reel format.

Q: Why is ERJ-8ENF48R7V marked "Not For New Designs"?

A: This designation indicates Panasonic has transitioned this part to end-of-life status and is not actively developing new versions or expanding production capacity. The part remains functionally equivalent and suitable for replacement in existing applications or field service, but should not be selected for new circuit designs where long-term availability cannot be guaranteed.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: All substitute parts conform to the 1206 (3216 Metric) package specification. Dimensional variations exist within standard tolerance: length ranges from 3.10mm to 3.20mm, width is 1.60mm, and height ranges from 0.60mm to 0.70mm. These variations are within PCB footprint design tolerances and do not create compatibility issues. Verify PCB layout clearances if height-constrained applications exist.

Q: Do the automotive AEC-Q200 certifications on substitute parts affect compatibility?

A: No. AEC-Q200 certification on CRCW120648R7FKEA and ERJ-8ENF48R7V represents additional qualification testing and reliability assurance beyond the base electrical specifications. These certifications do not alter electrical performance or mechanical fit. Parts with AEC-Q200 qualification are suitable for both automotive and non-automotive applications.

Q: What is the significance of MSL 1 (Unlimited) rating across all parts?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts can be stored and handled under standard warehouse conditions without special humidity control or pre-reflow baking procedures. This simplifies supply chain management and reduces manufacturing process complexity.
