Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73Z1JTTP is determined by the following critical parameters:

• Resistance value: 0 Ohms (jumper function)
• Package format: 0603 (1608 Metric)
• Composition: Thick Film
• Automotive qualification: AEC-Q200 rated
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 Compliant
• Termination count: 2-terminal configuration

The substitute part CRCW06030000Z0EA meets all these criteria, making it functionally and mechanically compatible with the RK73Z1JTTP in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RK73Z1JTTP and CRCW06030000Z0EA are active production parts with identical electrical specifications and automotive AEC-Q200 qualification. Selection between these parts should be based on:

• Packaging format availability: RK73Z1JTTP is supplied in Tape & Reel (TR) format; CRCW06030000Z0EA is available in Cut Tape (CT) and Digi-Reel® formats
• Inventory requirements: CRCW06030000Z0EA has significantly higher stock availability (69,170 pieces versus 936 pieces)
• Physical dimensions: Both parts fit the 0603 package specification with minor width and height variations within acceptable PCB assembly tolerances
• Compliance status: Both parts meet ROHS3, REACH Unaffected, and EAR99 classifications

Frequently Asked Questions (FAQ)

Q: Can CRCW06030000Z0EA be used as a direct replacement for RK73Z1JTTP on automotive PCBs?

A: Yes. Both parts are 0603 package jumper resistors with identical electrical ratings, AEC-Q200 automotive qualification, and operating temperature ranges. The minor dimensional differences (0.033" versus 0.031" width, 0.020" versus 0.022" height) are within standard PCB assembly tolerances for 0603 components.

Q: What is the functional difference between these two parts?

A: There is no functional difference. Both are 0 Ohms jumper resistors with identical resistance, tolerance, composition, and automotive ratings. They serve the same circuit function.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Both carry AEC-Q200 automotive qualification and MSL Level 1 moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability and packaging format requirements. CRCW06030000Z0EA offers higher inventory availability and multiple packaging options (Cut Tape and Digi-Reel®), while RK73Z1JTTP is supplied in Tape & Reel format.

Q: Are these parts interchangeable in existing designs?

A: Yes. The electrical and mechanical specifications are equivalent. PCB layouts designed for the 0603 package will accommodate both parts without modification.
