Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F9530CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 953 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility Requirements:

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

Regulatory & Environmental Requirements:

• RoHS3 Compliance (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

Power Rating Consideration: Substitute parts with identical 0.25W (1/4W) power rating are direct equivalents. Parts with higher power ratings (0.75W / 3/4W) in the same package are functional substitutes for applications where the original power rating is sufficient, but represent a design change and require circuit validation.

All identified substitute parts meet the electrical and mechanical criteria for direct substitution with the RCS3216F9530CS, with the exception of CRCW1206953RFKEAHP, which features a higher power rating and should be evaluated based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Recommended for New Designs):

AC1206FR-07953RL (YAGEO), CRCW1206953RFKEA (Vishay Dale), and RC1206FR-07953RL (YAGEO) are direct electrical and mechanical equivalents to the RCS3216F9530CS. All three parts maintain Active product status, identical electrical specifications, and full RoHS3 compliance. AC1206FR-07953RL and CRCW1206953RFKEA carry AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. RC1206FR-07953RL offers equivalent performance without automotive qualification. Selection among these three should be based on supply chain availability, packaging requirements (Tape & Reel), and application-specific certifications.

Higher Power Rating Substitute:

CRCW1206953RFKEAHP (Vishay Dale) provides a 0.75W (3/4W) power rating in the same 1206 package with identical resistance, tolerance, and temperature characteristics. This part is suitable for applications where the original 0.25W rating is insufficient, provided the circuit design accommodates the higher power dissipation capability. AEC-Q200 qualification and pulse withstanding features are included.

Legacy Part (Not Recommended for New Designs):

ERJ-8ENF9530V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries a "Not For New Designs" product status. This part should be used only for replacement or repair of existing assemblies where design continuity is required. High inventory availability (193,040 pieces) indicates this part remains in production for legacy support.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07953RL be used as a direct replacement for RCS3216F9530CS?

A: Yes. AC1206FR-07953RL matches all critical electrical parameters (953 Ohms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical specifications (1206 package, 2 terminations, thick film composition). Both parts are RoHS3 compliant with MSL Level 1 rating. The primary difference is that AC1206FR-07953RL includes AEC-Q200 automotive qualification, which is an additional feature rather than a limitation.

Q: What is the difference between CRCW1206953RFKEA and CRCW1206953RFKEAHP?

A: Both parts are manufactured by Vishay Dale and share identical resistance (953 Ohms), tolerance (±1%), package (1206), and temperature characteristics. The key difference is power rating: CRCW1206953RFKEA is rated at 0.25W (1/4W), while CRCW1206953RFKEAHP is rated at 0.75W (3/4W). CRCW1206953RFKEAHP also includes pulse withstanding capability. Selection depends on circuit power dissipation requirements.

Q: Why is ERJ-8ENF9530V marked "Not For New Designs"?

A: ERJ-8ENF9530V carries a "Not For New Designs" status, indicating that Panasonic has designated this part for legacy support only. New designs should utilize AC1206FR-07953RL, CRCW1206953RFKEA, or RC1206FR-07953RL, which maintain Active product status and full manufacturer support.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts are available in Tape & Reel (TR) packaging, which is standard for high-volume surface mount assembly operations. The RCS3216F9530CS is specified with "-" packaging notation in the provided data, while all substitutes explicitly list Tape & Reel availability.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed (AC1206FR-07953RL, CRCW1206953RFKEA, CRCW1206953RFKEAHP, ERJ-8ENF9530V, and RC1206FR-07953RL) are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the RCS3216F9530CS environmental specifications.

Q: What is the significance of AEC-Q200 qualification on AC1206FR-07953RL and CRCW1206953RFKEA?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. Parts carrying this qualification have undergone additional testing and validation. For non-automotive applications, AEC-Q200 qualification represents enhanced reliability assurance but is not a requirement for substitution. For automotive applications, AEC-Q200 qualification may be mandatory depending on design specifications.

Q: Can physical dimensions differences affect substitution?

A: Physical dimensions are within acceptable tolerance ranges across all substitute parts. Length variations range from 0.122" to 0.126" (3.10mm to 3.20mm), width is consistent at 0.063" (1.60mm), and height variations range from 0.024" to 0.028" (0.60mm to 0.70mm). These variations are within standard PCB assembly tolerances and do not affect substitution compatibility for standard surface mount assembly processes.
