Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 620 Ohms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Flexible Parameters (Allow Variation):

• Power Rating: 0.25W (1/4W) baseline; 0.75W (3/4W) acceptable as upgrade
• Packaging format: Tape & Reel (TR) acceptable
• Manufacturer: Multiple qualified sources
• Features: Automotive AEC-Q200 qualification optional; Moisture Resistant feature maintained across all substitutes

Substitution Categories:

Direct Equivalents maintain identical electrical and mechanical specifications with interchangeable performance.

Upgrade Substitutes provide enhanced capabilities (automotive qualification, higher power rating) while maintaining core electrical parameters and package compatibility.

Similar Substitutes meet all mandatory parameters with minor dimensional variations within tolerance and optional feature enhancements.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): CR1206-FX-6200ELF (Bourns Inc.) and RC1206FR-07620RL (YAGEO) are direct functional equivalents to RC3216F621CS. Both maintain active production status and identical electrical specifications. Selection between these options is based on supply availability and procurement lead times.

For Automotive Applications: AC1206FR-07620RL (YAGEO) and CRCW1206620RFKEA (Vishay Dale) are qualified to AEC-Q200 automotive standards while maintaining all core electrical parameters. These parts are suitable for automotive-grade circuit designs requiring enhanced reliability qualification.

For Enhanced Power Dissipation: CRCW1206620RFKEAHP (Vishay Dale) provides 0.75W (3/4W) power rating with pulse withstanding capability in the same 1206 package footprint. This upgrade substitute accommodates higher thermal stress applications while maintaining electrical specifications and automotive AEC-Q200 qualification.

Obsolescence Consideration: ERJ-8ENF6200V (Panasonic Electronic Components) carries "Not For New Designs" status. While functionally equivalent and currently in stock, this part should not be selected for new product development. Existing designs using this part may continue procurement during transition periods.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206620RFKEAHP (0.75W) be used as a direct replacement for RC3216F621CS (0.25W)?

A: Yes. The 0.75W rating represents enhanced thermal capability within the same 1206 package. All electrical parameters (620 Ω, ±1%, ±100ppm/°C, -55°C to 155°C) are identical. The higher power rating does not degrade performance in 0.25W applications; it provides additional thermal margin. PCB footprint compatibility is maintained.

Q: What is the difference between automotive-qualified parts (AC1206FR-07620RL, CRCW1206620RFKEA) and standard parts (RC1206FR-07620RL)?

A: Automotive-qualified parts meet AEC-Q200 reliability standards, which specify enhanced testing for temperature cycling, moisture resistance, and long-term stability. Standard parts meet general industrial specifications. Electrical performance is identical. Automotive parts are required for automotive applications; standard parts are suitable for consumer and industrial electronics.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within specification. RC3216F621CS and CRCW1206620RFKEA measure 0.126" L × 0.063" W. RC1206FR-07620RL and AC1206FR-07620RL measure 0.122" L × 0.063" W. Height variations range from 0.024" to 0.030" maximum seated height. All parts fit standard 1206 PCB pads without modification. Verify PCB layout clearances for height-sensitive applications.

Q: Why is ERJ-8ENF6200V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product designs. Existing inventory remains available for legacy product support. New designs should select from active-status alternatives: CR1206-FX-6200ELF, RC1206FR-07620RL, AC1206FR-07620RL, CRCW1206620RFKEA, or CRCW1206620RFKEAHP.

Q: Are all substitute parts ROHS3 compliant and MSL 1 rated?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching RC3216F621CS specifications. No additional handling or storage precautions are required when substituting between these parts.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-07620RL (YAGEO) has 132,517 units in stock, providing maximum supply security. CRCW1206620RFKEAHP has the lowest inventory at 5,761 units. Inventory levels should be verified at time of procurement.
