Key Parameters

Substitute Part Grouping Explanation

Substitution of the Z0603C600ASMST is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Impedance value: 60 Ohms @ 100 MHz
• Filter type: Signal Line (single line configuration)
• Current rating: 800mA maximum
• DC resistance: 100mOhm maximum

Mechanical Specifications:

• Package type: 0603 (1608 Metric) surface mount
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Height: 0.037" (0.95mm) maximum
• Mounting method: Surface mount

Environmental & Compliance:

• Operating temperature: -55°C ~ 125°C
• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must match all parameters listed above. Parts meeting these criteria are classified as parametric equivalents and are suitable for direct replacement in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the GZ1608U600CTF or MMZ1608R600ATA00 be used as direct replacements for the Z0603C600ASMST?

A: Yes. Both substitute parts meet all electrical and mechanical parameters of the original component, including impedance value, current rating, DC resistance, package dimensions, and operating temperature range. Direct substitution is supported without circuit modification.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Z0603C600ASMST is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute parts GZ1608U600CTF and MMZ1608R600ATA00 are active products, ensuring reliable long-term supply and continued manufacturing support.

Q: Are there dimensional differences between the substitute parts and the original?

A: The GZ1608U600CTF and Z0603C600ASMST share identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm). The MMZ1608R600ATA00 specifies a width of 0.032" (0.80mm), which represents a tolerance variation within standard manufacturing specifications for 0603 (1608 Metric) packages and does not affect circuit board layout or assembly compatibility.

Q: Do the substitute parts maintain the same compliance certifications?

A: Yes. Both GZ1608U600CTF and MMZ1608R600ATA00 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original Z0603C600ASMST. Moisture sensitivity level remains at MSL 1 (Unlimited) for all parts.

Q: What packaging formats are available for the substitute parts?

A: Both substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original Z0603C600ASMST packaging format is not specified in the provided data.

Q: Are there any electrical performance differences between the three parts?

A: No. All three parts specify identical electrical characteristics: 60 Ohms impedance at 100 MHz, 800mA maximum current rating, and 100mOhm maximum DC resistance. Performance in signal line filtering applications is equivalent.

Q: Which substitute part should be selected for new designs?

A: Both GZ1608U600CTF and MMZ1608R600ATA00 are suitable for new designs. Selection may be based on supplier availability, procurement lead times, and established vendor relationships. Both parts provide equivalent performance and long-term supply assurance as active products.
