Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1102F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 11 kOhms
• Tolerance: ±1%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height - Seated (Max): 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Quality Parameters (Must Match or Exceed):

• Automotive rating: AEC-Q200
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• Composition: Thick Film

Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or board layout modification. Compliance certifications must meet or exceed the original part specifications.

Application Continuity:

Direct substitution is permissible for all applications where RK73G1HTTC1102F was originally specified. No circuit redesign, board layout modification, or performance re-qualification is required. The parts are functionally and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1102F be used as a direct replacement for RK73G1HTTC1102F?

A: Yes. The RK73G1HTTCM1102F is a direct equivalent substitute. All electrical parameters (11 kOhms ±1%, 0.05W, ±50ppm/°C, -55°C ~ 155°C), mechanical specifications (0201 package, 0.60mm x 0.30mm), and compliance certifications (AEC-Q200, ROHS3, MSL 1) are identical. No design changes are required.

Q: What is the difference between RK73G1HTTC1102F and RK73G1HTTCM1102F?

A: The primary difference is product status. RK73G1HTTC1102F is marked "Not For New Designs," while RK73G1HTTCM1102F is "Active." The "M" designation in the part number indicates the active production variant. All technical specifications remain identical.

Q: Are these parts pin-compatible and footprint-compatible?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010", 0.26mm). They share the same two-termination configuration and are fully compatible with existing PCB layouts and assembly processes.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC1102F and RK73G1HTTCM1102F carry AEC-Q200 automotive qualification, making them suitable for automotive-grade applications requiring high reliability and temperature stability across the -55°C ~ 155°C operating range.

Q: What is the significance of the "M" in RK73G1HTTCM1102F?

A: The "M" designation indicates this is the current active production part number within the RK73G series. It represents the manufacturer's current offering for this specific resistor value and specification, while the original part number without "M" has been transitioned to legacy status.

Q: Are there any packaging differences between these parts?

A: The original part RK73G1HTTC1102F is specified as Tape & Reel (TR) packaging. The substitute part RK73G1HTTCM1102F does not have packaging specification provided in the available data. Confirm packaging requirements with the supplier if tape and reel format is mandatory for your assembly process.

Q: Can I mix these parts in the same production lot?

A: Yes. Since both parts are electrically and mechanically identical with matching AEC-Q200 and ROHS3 certifications, they can be used interchangeably within the same assembly or production batch without affecting circuit performance or reliability.
