Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73Z1HTTC is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 0 Ohms (jumper function)
• 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)
• REACH compliance

Acceptable Variations:

• Composition: Metal Element or Thick Film (both provide 0 Ohm jumper function)
• Operating temperature range: Minimum -55°C to maximum 125°C or higher (RK73Z1HTTC operates -55°C ~ 155°C)
• Automotive qualification: AEC-Q200 rated or non-rated (automotive rating is not required for substitution)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

All substitute parts listed maintain identical electrical function, mechanical fit, and regulatory compliance within the specified parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Manufacturer Recommended): RK73Z1HTTCM from KOA Speer Electronics is the manufacturer-recommended upgrade path. This part maintains identical electrical and mechanical specifications to the RK73Z1HTTC while offering Active product status. Both components share the same manufacturer, series designation (RK73Z), AEC-Q200 automotive qualification, and extended operating temperature range (-55°C ~ 155°C). The transition from Metal Element to Thick Film composition does not affect jumper functionality. This selection ensures design continuity with the original component manufacturer.

Direct Substitutes (Cross-Manufacturer): RC0603J000CS (Samsung Electro-Mechanics), CRCW02010000Z0ED (Vishay Dale), RC0201FR-070RL (YAGEO), and RC0201JR-070RL (YAGEO) are functionally equivalent alternatives. All four parts meet the critical matching parameters: 0 Ohms resistance, 0201 package format, identical physical dimensions, RoHS3 compliance, and MSL 1 rating. These components are in Active product status with established supply availability.

Temperature Consideration: RC0603J000CS, RC0201FR-070RL, and RC0201JR-070RL operate within -55°C ~ 125°C range, which is 30°C lower than the RK73Z1HTTC maximum of 155°C. Selection of these parts is appropriate for applications with maximum operating temperatures not exceeding 125°C. CRCW02010000Z0ED and RK73Z1HTTCM both support the full -55°C ~ 155°C range, matching the original component specification.

Regulatory Compliance: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can RK73Z1HTTCM replace RK73Z1HTTC in existing designs? A: Yes. RK73Z1HTTCM is the manufacturer-recommended substitute with identical electrical function, mechanical fit, and operating specifications. The composition change from Metal Element to Thick Film does not affect 0 Ohm jumper performance. Both parts are AEC-Q200 qualified and support -55°C ~ 155°C operation.

Q: What is the difference between Metal Element and Thick Film composition in 0 Ohm jumpers? A: Both compositions provide identical 0 Ohm electrical function and are mechanically interchangeable in the 0201 package. Composition differences do not affect substitution eligibility for jumper applications.

Q: Are cross-manufacturer substitutes (Samsung, Vishay, YAGEO) fully compatible? A: Yes, provided operating temperature requirements do not exceed 125°C. RC0603J000CS, RC0201FR-070RL, and RC0201JR-070RL all match critical parameters: 0 Ohms resistance, 0201 package, identical dimensions, RoHS3 compliance, and MSL 1 rating. CRCW02010000Z0ED supports the full -55°C ~ 155°C range.

Q: Why is RK73Z1HTTC marked "Not For New Designs"? A: This designation indicates end-of-life status for the original part. RK73Z1HTTCM represents the active product line continuation from KOA Speer Electronics. For new designs, RK73Z1HTTCM or other Active-status alternatives are recommended.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect substitution? A: No. Packaging format differences (Tape & Reel or Cut Tape & Digi-Reel®) do not affect electrical or mechanical compatibility. Selection depends on manufacturing process requirements and supply chain preferences.

Q: What inventory levels are available for each substitute? A: CRCW02010000Z0ED (Vishay Dale) offers the highest inventory at 1,474,000 pieces. RC0201JR-070RL (YAGEO) provides 118,632 pieces. RK73Z1HTTCM (KOA) has 1,026 pieces. RC0201FR-070RL (YAGEO) has 10,062 pieces. RC0603J000CS (Samsung) has 794 pieces. Original RK73Z1HTTC stock remains at 6,244,238 pieces.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original RK73Z1HTTC component.
