• Resistance value: 300 Ohms
• Tolerance: ±0.5%
• Power rating: 0.05W (1/20W)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package format: 0201 (0603 Metric)
• Physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Height seated maximum: 0.010" (0.26mm)
• Number of terminations: 2

Compliance & Composition (Must Match Exactly):

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

The substitute part RK73G1HTTCM3000D meets all these criteria and is manufactured by the same supplier (KOA Speer Electronics, Inc.) within the same product series (RK73G).

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3000D is a direct functional equivalent to the RK73G1HTTC3000D. Both components are manufactured by KOA Speer Electronics, Inc. and belong to the same RK73G series. The critical distinction is product status: the main part is classified as "Not For New Designs," while the substitute part maintains "Active" status.

For applications requiring the 300 Ohm ±0.5% 0.05W thick film chip resistor in 0201 package with AEC-Q200 automotive qualification, the RK73G1HTTCM3000D provides full electrical and mechanical compatibility. All compliance certifications (ROHS3, AEC-Q200, MSL 1) are maintained. The substitute part is suitable for both new production and replacement applications where the original part number is no longer recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM3000D be used as a direct replacement for RK73G1HTTC3000D?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (300 Ohms), tolerance (±0.5%), power rating (0.05W), package format (0201), temperature coefficient (±50ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The substitute part is manufactured by the same supplier within the same product series.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. RK73G1HTTC3000D is classified as "Not For New Designs," while RK73G1HTTCM3000D maintains "Active" status. The "M" designation in the substitute part number indicates a current production variant. All electrical specifications, mechanical dimensions, and compliance certifications are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification standards and are rated for the full automotive temperature range (-55°C ~ 155°C). Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably on PCBs?

A: Yes. The 0201 package format (0.60mm x 0.30mm) and all physical dimensions are identical. Both parts have the same footprint, height (0.010" maximum seated), and two-terminal configuration. No PCB layout modifications are required.

Q: Which part should be specified for new production?

A: The RK73G1HTTCM3000D should be specified for new production designs. This part maintains active status and ensures long-term supply availability. The original part number (RK73G1HTTC3000D) is designated "Not For New Designs" and should be reserved for maintenance and replacement applications only.

Q: Are there any performance differences between these parts?

A: No. Both parts have identical electrical performance characteristics: ±0.5% tolerance, ±50ppm/°C temperature coefficient, 0.05W power rating, and -55°C ~ 155°C operating range. Performance in circuit applications is equivalent.
