Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F755CS is determined by strict alignment of the following critical parameters:

Core Electrical Parameters (Non-Negotiable):

• Resistance value: 7.5 MOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Thick Film

Core Mechanical Parameters (Non-Negotiable):

• Package: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance required
• MSL rating: 1 (Unlimited) or equivalent

All substitute parts listed meet these core requirements. Additional features such as automotive AEC-Q200 qualification represent enhanced specifications and do not disqualify parts from substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Standard Applications): RC1206FR-077M5L (YAGEO) provides direct electrical and mechanical equivalence to the RC3216F755CS. Both parts share identical core specifications: 7.5 MOhms ±1%, 0.25W power rating, ±100 ppm/°C temperature coefficient, and ROHS3 compliance. This part is suitable for applications where automotive qualification is not required.

Upgrade Options (Enhanced Reliability for Automotive/Industrial Applications): KTR18EZPF7504 (Rohm Semiconductor), RMCF1206FT7M50 (Stackpole Electronics), and CRCW12067M50FKEA (Vishay Dale) all carry AEC-Q200 automotive qualification. These parts maintain full electrical compatibility while providing enhanced reliability screening and qualification documentation. Selection among these three depends on inventory availability and packaging requirements (Tape & Reel).

Temperature Coefficient Consideration: RMCF1206FT7M50 specifies ±200 ppm/°C temperature coefficient compared to ±100 ppm/°C for other alternatives. This difference is acceptable for most applications but should be verified if circuit design requires tighter temperature stability.

Physical Dimension Variations: All parts conform to 1206 package footprint. Minor height variations (0.024" to 0.028" seated height) are within standard PCB assembly tolerances and do not affect interchangeability.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-077M5L replace RC3216F755CS directly? A: Yes. RC1206FR-077M5L is a direct equivalent with identical electrical specifications (7.5 MOhms ±1%, 0.25W, ±100 ppm/°C) and mechanical compatibility (1206 package). Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the standard RC3216F755CS and the AEC-Q200 qualified alternatives? A: AEC-Q200 qualified parts (KTR18EZPF7504, RMCF1206FT7M50, CRCW12067M50FKEA) undergo additional automotive-grade reliability screening and qualification testing. The RC3216F755CS and RC1206FR-077M5L do not carry this qualification. Electrical performance is equivalent; qualification status differs.

Q: Are all substitute parts available in Tape & Reel packaging? A: RC1206FR-077M5L, KTR18EZPF7504, RMCF1206FT7M50, and CRCW12067M50FKEA are all supplied in Tape & Reel (TR) packaging. The original RC3216F755CS is supplied in standard packaging format.

Q: Does the ±200 ppm/°C temperature coefficient of RMCF1206FT7M50 affect substitution suitability? A: RMCF1206FT7M50 remains electrically compatible. The ±200 ppm/°C specification indicates greater resistance drift over temperature compared to ±100 ppm/°C alternatives. Substitution is valid; circuit design must accommodate this specification if temperature stability is critical.

Q: Can these parts be used interchangeably on the same PCB assembly? A: Yes. All listed parts share identical 1206 (3216 Metric) footprint, 2-termination configuration, and mounting requirements. Physical height variations (0.024" to 0.028") are within standard PCB assembly process tolerances.

Q: Which substitute part offers the best inventory availability? A: RC1206FR-077M5L (YAGEO) shows highest inventory at 51,054 pieces. CRCW12067M50FKEA (Vishay Dale) provides 18,558 pieces. Both represent substantial stock levels for production requirements.
