RCS3216F1691CS Equivalent & Substitute Parts Reference

Part Overview

The RCS3216F1691CS is a 1.69 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, with operating temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package type and dimensions), and environmental ratings. Alternative sources provide equivalent performance for applications where the original part is unavailable or where specific certifications are required.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence Requirements:

• Resistance value: 1.69 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 to 155°C (exact match)

Mechanical Compatibility Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (all substitutes meet this requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (all substitutes meet this requirement)

All four substitute parts meet these criteria. Differences in features (automotive AEC-Q200 certification, anti-sulfur properties) and minor dimensional variations do not affect functional substitutability for standard applications.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

RC1206FR-071K69L (YAGEO) and AC1206FR-071K69L (YAGEO) are recommended as primary alternatives. Both parts maintain active product status and provide full electrical and mechanical equivalence to the RCS3216F1691CS. RC1206FR-071K69L offers the highest inventory availability (44,477 pcs) and is suitable for general applications. AC1206FR-071K69L includes automotive AEC-Q200 certification and is appropriate for automotive-grade applications.

CRCW12061K69FKEA (Vishay Dale) is a secondary alternative with active product status and automotive AEC-Q200 certification. This part provides equivalent performance with substantial inventory availability (19,802 pcs).

Restricted Substitute (Not For New Designs):

ERJ-8ENF1691V (Panasonic) carries a "Not For New Designs" product status designation. While this part meets all electrical and mechanical equivalence criteria, it is not recommended for new circuit designs. This part may be used only for legacy system maintenance or replacement applications where the original part specification is mandatory.

Feature Considerations:

The RCS3216F1691CS includes anti-sulfur properties in addition to moisture resistance. Substitute parts AC1206FR-071K69L and CRCW12061K69FKEA include automotive AEC-Q200 certification, which is not present in the original part. These certifications represent additional capabilities and do not restrict substitutability in standard applications.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071K69L be used as a direct replacement for RCS3216F1691CS?

A: Yes. RC1206FR-071K69L meets all electrical specifications (1.69 kOhms ±1%, 0.25W), operates across the same temperature range (-55°C to 155°C), and uses the identical 1206 package. Both parts are ROHS3 compliant with MSL 1 rating. The part is in active production status.

Q: What is the difference between AC1206FR-071K69L and RC1206FR-071K69L?

A: Both are YAGEO 1206 resistors with identical electrical specifications. AC1206FR-071K69L includes automotive AEC-Q200 certification and is specified for automotive applications. RC1206FR-071K69L is specified for general industrial applications. The AEC-Q200 certification in AC1206FR-071K69L represents additional qualification testing and does not affect compatibility in non-automotive circuits.

Q: Why is ERJ-8ENF1691V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development of this product line. While the part meets all electrical and mechanical equivalence criteria and remains available in inventory, it is not recommended for incorporation into new circuit designs. Use this part only for replacement or maintenance of existing systems.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. Length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), and height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations fall within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

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

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, identical to the RCS3216F1691CS. This rating indicates no moisture sensitivity restrictions for storage or handling.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-071K69L (YAGEO) has the highest inventory with 44,477 pieces in stock, followed by ERJ-8ENF1691V (Panasonic) with 32,860 pieces.
