Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Resistance value (17.4 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Equivalence: Package type (1206/3216 Metric) and footprint dimensions must be identical to ensure PCB compatibility without layout modifications.

Environmental & Compliance Equivalence: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL 1 rating must be maintained.

Composition: Thick film construction is required for thermal and frequency response characteristics.

All identified substitutes meet these criteria. Automotive-rated variants (AEC-Q200) are included as they exceed standard reliability requirements while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, Standard Applications): CR1206-FX-1742ELF (Bourns), RC1206FR-0717K4L (YAGEO), and CRCW120617K4FKEA (Vishay Dale) are recommended for new designs. All three maintain active production status, ROHS3 compliance, and MSL 1 rating. Bourns and YAGEO variants feature moisture-resistant construction matching the original RC3216F1742CS specification.

Automotive Applications (AEC-Q200 Rated): RMCF1206FT17K4 (Stackpole Electronics) and CRCW120617K4FKEA (Vishay Dale) are qualified to AEC-Q200 automotive standards. These parts exceed standard reliability requirements and are suitable for automotive and industrial applications requiring enhanced qualification.

Legacy/Inventory Considerations: ERJ-8ENF1742V (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status. This part remains suitable for sustaining production or field repairs of existing assemblies where inventory exists.

Inventory Availability: Substitute parts demonstrate higher stock levels: CR1206-FX-1742ELF (25,927 units), ERJ-8ENF1742V (90,008 units), RC1206FR-0717K4L (19,220 units), RMCF1206FT17K4 (5,827 units), and CRCW120617K4FKEA (13,659 units) compared to the main part (1,175 units).

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-1742ELF replace RC3216F1742CS directly on the PCB?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions, footprint, and electrical specifications (17.4 kOhms ±1%, 0.25W, ±100ppm/°C). No PCB layout modifications are required.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: Moisture-resistant variants (CR1206-FX-1742ELF, RC1206FR-0717K4L) are optimized for humidity environments. Automotive AEC-Q200 variants (RMCF1206FT17K4, CRCW120617K4FKEA) undergo additional qualification testing for automotive reliability and temperature cycling. Both meet the operating temperature range of -55°C to 155°C and ROHS3 compliance.

Q: Why is ERJ-8ENF1742V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While electrically and mechanically equivalent, it is reserved for sustaining existing production or field service applications. New designs should select from active-status alternatives.

Q: Are all substitute parts MSL 1 rated?

A: Yes. All identified substitutes carry MSL 1 (Unlimited) moisture sensitivity level, matching the original RC3216F1742CS. This rating permits unlimited shelf life without moisture bake-out requirements.

Q: Can I use CRCW120617K4FKEA in non-automotive applications?

A: Yes. AEC-Q200 automotive qualification exceeds standard commercial requirements. CRCW120617K4FKEA is fully compatible with commercial, industrial, and consumer applications requiring 17.4 kOhms ±1% 0.25W 1206 resistors.

Q: What is the maximum seated height difference among substitutes?

A: Seated heights range from 0.024" (0.60mm) for CRCW120617K4FKEA to 0.030" (0.75mm) for CR1206-FX-1742ELF. These variations remain within standard 1206 package tolerances and do not affect PCB assembly or component clearance in typical applications.
