Substitute Part Grouping Explanation

Substitute parts for the WR12X8663FTL are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence:

• Resistance value: 866 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence:

• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Equivalence:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The CR088663F from Meritek meets all electrical and mechanical requirements for direct substitution. Minor dimensional variations in length (0.126" vs 0.122") and height (0.024" vs 0.030") remain within acceptable tolerances for 1206 package specifications and do not affect circuit performance or PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the WR12X8663FTL and CR088663F are Active product status components with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by availability and supply chain requirements rather than technical performance differences.

The WR12X8663FTL (Walsin Technology Corporation) is suitable for applications where Walsin sourcing is preferred or contractually specified. The CR088663F (Meritek) provides equivalent functionality with higher inventory availability (25,660 pieces versus 950 pieces), making it the preferred choice for high-volume production runs or time-sensitive procurement scenarios.

Both components satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements. Moisture Sensitivity Level 1 (Unlimited) indicates no special handling or storage conditions are required for either part.

Frequently Asked Questions (FAQ)

Q: Can CR088663F be used as a direct replacement for WR12X8663FTL in existing designs?

A: Yes. Both components share identical electrical specifications (866 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C), identical package type (1206 / 3216 Metric), and identical compliance certifications. The components are mechanically and electrically interchangeable.

Q: What are the dimensional differences between these parts?

A: WR12X8663FTL dimensions are 0.122" L x 0.063" W with 0.030" maximum seated height. CR088663F dimensions are 0.126" L x 0.063" W with 0.024" maximum seated height. Both fall within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, and carry identical HTSUS code 8533.21.0030. Moisture Sensitivity Level 1 applies to both components.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain and inventory availability. CR088663F offers significantly higher stock levels (25,660 pieces) compared to WR12X8663FTL (950 pieces), making it the preferred choice for new production designs unless specific manufacturer requirements exist.

Q: Do these parts require different handling or storage procedures?

A: No. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control, baking, or storage requirements are necessary for either part.

Q: Are the temperature coefficients identical?

A: Yes. Both WR12X8663FTL and CR088663F have a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C ~ 155°C.
