CDCM1802RGTR Equivalent & Substitute Parts

Part Overview

The CDCM1802RGTR is an active Clock/Timing IC functioning as a fanout buffer with 1:2 distribution capability, designed for high-speed clock signal distribution applications. This device operates at frequencies up to 800 MHz and supports multiple input/output signal standards including LVCMOS, LVPECL, and LVTTL. The part is currently in active production status with 1275 units available in new original inventory. Substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across the same product family.

Substitute Part Grouping Explanation

The CDCM1802RGTR qualifies for substitution with CDCM1802RGTT based on strict parametric equivalence. Both parts share identical electrical and mechanical specifications across all critical selection criteria:

• Identical input/output ratio (1:2)
• Identical maximum frequency (800 MHz)
• Identical supply voltage range (3V ~ 3.6V)
• Identical operating temperature range (-40°C ~ 85°C)
• Identical package type (16-VFQFN Exposed Pad)
• Identical signal standard support (LVCMOS, LVPECL, LVTTL input; LVCMOS, LVPECL output)
• Identical compliance certifications (ROHS3, REACH Unaffected)

The only distinction between these parts is packaging format: CDCM1802RGTR is supplied in standard packaging, while CDCM1802RGTT is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not alter functional or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both CDCM1802RGTR and CDCM1802RGTT are active production parts from Texas Instruments with full compliance to ROHS3 and REACH requirements. Selection between these parts should be based on procurement and assembly requirements:

• CDCM1802RGTR is appropriate for applications requiring standard packaging format with current inventory of 1275 units available.
• CDCM1802RGTT is appropriate for high-volume manufacturing environments utilizing automated tape-and-reel feeding systems, with current inventory of 1901 units available.

Both parts maintain identical electrical performance, thermal characteristics, and signal integrity specifications. PCB layout, schematic design, and functional implementation remain unchanged between these variants.

Frequently Asked Questions (FAQ)

Q: Can CDCM1802RGTT be used as a direct replacement for CDCM1802RGTR in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. If your assembly process supports tape-and-reel input, CDCM1802RGTT is a direct substitute.

Q: What is the difference between standard packaging and Tape & Reel (TR) format?

A: Standard packaging typically uses trays or tubes for manual handling and lower-volume applications. Tape & Reel format is designed for automated pick-and-place assembly equipment used in high-volume manufacturing. The component itself is identical.

Q: Are there any signal integrity differences between these two part numbers?

A: No. Both parts are manufactured to identical specifications and support the same frequency range (800 MHz), signal standards (LVCMOS, LVPECL, LVTTL), and supply voltage (3V ~ 3.6V).

Q: Do both parts require the same PCB footprint?

A: Yes. Both parts use the 16-VQFN (3x3) package with identical pin configuration and exposed pad design.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 2 with a 1-year floor life. Standard moisture control procedures during storage and handling apply.
