Substitute Part Grouping Explanation

Substitution for the CRCW040212R0DKEDP is determined by strict equivalence across the following critical parameters:

• Resistance value: 12 Ohms
• Tolerance: ±0.5%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The RC0402DR-0712RL from YAGEO meets all these parameters and qualifies as a direct substitute. This part maintains identical electrical specifications and mechanical dimensions while offering active product status and moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can the RC0402DR-0712RL be used as a direct replacement for the CRCW040212R0DKEDP?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 12 Ohm resistance, ±0.5% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. PCB layout and assembly processes require no modification.

Q: What is the significance of the obsolete status of the CRCW040212R0DKEDP?

A: Obsolete status indicates the part is no longer manufactured or supported by Vishay Dale. The RC0402DR-0712RL, with active status, ensures continued availability and supply chain reliability for new production and field replacements.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant with MSL 1 rating. The YAGEO part includes REACH Unaffected status. No compliance barriers exist for substitution.

Q: Does the moisture-resistant feature of the RC0402DR-0712RL affect compatibility?

A: No. Moisture-resistant construction is an enhancement that does not alter electrical performance or mechanical fit. It provides additional environmental protection without introducing incompatibility.

Q: What packaging options are available for the RC0402DR-0712RL?

A: The RC0402DR-0712RL is supplied in Tape & Reel (TR) format, standard for automated assembly processes. Confirm packaging compatibility with your procurement and assembly requirements.
