Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216F1782CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 17.8 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

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

Compliance & Environmental (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Physical dimensions show minor variations within acceptable tolerances for 1206 package specifications. Product status and specific feature sets (moisture-resistant vs. automotive AEC-Q200) are noted for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: Select CR1206-FX-1782ELF (Bourns Inc.) or RC1206FR-0717K8L (YAGEO) as primary substitutes. Both components maintain Active product status, moisture-resistant construction, and full ROHS3 compliance. CR1206-FX-1782ELF offers highest inventory availability (25965 pcs).

For Automotive Applications: Select RMCF1206FT17K8 (Stackpole Electronics Inc) or CRCW120617K8FKEA (Vishay Dale) when AEC-Q200 automotive qualification is required. Both components are Active status with automotive-grade specifications and equivalent electrical parameters.

Avoid for New Designs: ERJ-8ENF1782V (Panasonic Electronic Components) carries "Not For New Designs" status despite meeting all electrical and mechanical specifications. This component remains available for legacy system maintenance and repair applications only.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). No additional environmental qualification testing is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0717K8L replace RC3216F1782CS in existing designs?

A: Yes. RC1206FR-0717K8L (YAGEO) meets all electrical specifications (17.8 kΩ ±1%, 0.25W), operates across identical temperature range (-55°C ~ 155°C), and uses identical 1206 package format. Physical dimensions show minor variation (3.10mm vs 3.20mm length) within 1206 package tolerance. Both components are Active status with ROHS3 compliance.

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

A: Moisture-resistant variants (CR1206-FX-1782ELF, RC1206FR-0717K8L, RC3216F1782CS) are optimized for general industrial environments. Automotive AEC-Q200 variants (RMCF1206FT17K8, CRCW120617K8FKEA, ERJ-8ENF1782V) undergo additional qualification testing for automotive reliability standards. Both feature identical electrical specifications and operating ranges. Selection depends on application environment requirements.

Q: Why is ERJ-8ENF1782V marked "Not For New Designs"?

A: ERJ-8ENF1782V carries this status from Panasonic Electronic Components, indicating the product line is in end-of-life phase. The component remains electrically and mechanically equivalent and suitable for legacy system repairs. New designs should select Active-status alternatives: CR1206-FX-1782ELF, RC1206FR-0717K8L, RMCF1206FT17K8, or CRCW120617K8FKEA.

Q: Are physical dimension variations between substitute parts significant?

A: Physical dimensions show minor variations within 1206 package specification tolerance. Height ranges from 0.024" to 0.030" (0.60mm to 0.75mm), and length varies from 0.122" to 0.126" (3.10mm to 3.20mm). These variations are within standard PCB footprint design margins and do not affect electrical performance or mechanical fit in standard 1206 land patterns.

Q: Which substitute part offers best inventory availability?

A: CR1206-FX-1782ELF (Bourns Inc.) provides highest inventory with 25965 pcs in stock, followed by ERJ-8ENF1782V (Panasonic) with 48920 pcs. However, ERJ-8ENF1782V is not recommended for new designs. For new designs, CR1206-FX-1782ELF is the optimal choice combining availability, Active status, and full compliance.

Q: Can substitute parts be mixed in the same circuit board assembly?

A: Yes. All substitute parts meet identical electrical specifications, tolerance, power rating, and operating temperature range. Mixed usage across the same PCB is electrically valid. However, procurement and quality control practices typically standardize on single part number per design to simplify inventory management and traceability.
