Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F681CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 680 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

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

Environmental & Compliance (Must Match):

• RoHS3 Compliance
• MSL 1 rating
• REACH Unaffected status

Power Rating Consideration: Substitute parts are grouped into two categories: standard 0.25W (1/4W) rating and enhanced 0.75W (3/4W) rating. The 0.75W variant provides higher power dissipation capability while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (0.25W Power Rating):

Select from the following Active status parts for new designs:

• AF1206FR-07680RL (YAGEO): Automotive AEC-Q200 qualified with anti-sulfur protection. Suitable for automotive and industrial applications requiring enhanced reliability.
• AC1206FR-07680RL (YAGEO): Automotive AEC-Q200 qualified with moisture resistance. High inventory availability (43,940 pcs).
• CR1206-FX-6800ELF (Bourns Inc.): Moisture-resistant thick film composition. Established reliability in industrial applications.
• CRCW1206680RFKEA (Vishay Dale): Automotive AEC-Q200 qualified. Compact height profile (0.024" seated height).
• RC1206FR-07680RL (YAGEO): Moisture-resistant composition with extensive inventory (2,316,712 pcs). Suitable for high-volume production.

For Enhanced Power Dissipation Applications (0.75W Power Rating):

• CRCW1206680RFKEAHP (Vishay Dale): Automotive AEC-Q200 qualified with pulse withstanding capability. Provides higher power handling in the same 1206 package footprint.

Obsolescence Consideration:

• ERJ-8ENF6800V (Panasonic Electronic Components): Classified as "Not For New Designs." Use only for legacy system maintenance or repair applications where original part compatibility is required.

Frequently Asked Questions (FAQ)

Q1: Can I substitute the RCS3216F681CS with any of the listed parts without circuit redesign?

A: Yes, all listed Active status parts with 0.25W power rating are direct substitutes. They share identical electrical specifications (680 Ω ±1%, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (1206 package), and environmental compliance (ROHS3, MSL 1). No circuit redesign is required.

Q2: What is the difference between the 0.25W and 0.75W variants?

A: The CRCW1206680RFKEAHP provides 0.75W power rating compared to the standard 0.25W rating of other substitutes. This higher power rating allows greater current handling and heat dissipation in the same 1206 package footprint. Select the 0.75W variant only if circuit analysis requires higher power dissipation capability.

Q3: Are automotive AEC-Q200 qualified parts necessary for my application?

A: Automotive AEC-Q200 qualification is not required for all applications. It indicates enhanced reliability testing and qualification for automotive environments. Select AEC-Q200 qualified parts (AF1206FR-07680RL, AC1206FR-07680RL, CRCW1206680RFKEA, CRCW1206680RFKEAHP, ERJ-8ENF6800V) only if your application requires automotive-grade reliability or operates in harsh environmental conditions.

Q4: Why is ERJ-8ENF6800V marked "Not For New Designs"?

A: The ERJ-8ENF6800V is classified as "Not For New Designs" by Panasonic Electronic Components, indicating the part is in end-of-life status. Use this part only for maintenance, repair, or legacy system support where original part compatibility is mandatory. For new designs, select from Active status alternatives.

Q5: What packaging options are available?

A: Substitute parts are supplied in two packaging formats: Tape & Reel (TR) for automated assembly and Cut Tape (CT) with Digi-Reel® for manual or mixed-volume applications. Select packaging based on your production volume and assembly process requirements.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the RCS3216F681CS. All parts carry MSL 1 (Unlimited) moisture sensitivity rating.
