• Same package designation: 1206 (3216 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Compatible termination count: 2 terminations
• Equivalent or superior environmental compliance: ROHS3 Compliant

Physical dimensions may vary within acceptable tolerances for PCB assembly compatibility. Substitute parts are grouped by manufacturer and product status to facilitate selection based on availability and application requirements.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, CRCW1206105RFKEA (Vishay Dale) and RC1206FR-07105RL (YAGEO) are preferred substitutes as both maintain Active product status with full ROHS3 compliance. CRCW1206105RFKEA includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. RC1206FR-07105RL features moisture-resistant construction for enhanced environmental protection.

ERJ-8ENF1050V (Panasonic Electronic Components) is electrically and mechanically equivalent but carries "Not For New Designs" status, making it suitable only for legacy system maintenance or replacement applications where existing inventory must be maintained.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206105RFKEA be used as a direct replacement for RMCS1206FT105R?

A: Yes. Both parts share identical electrical specifications (105 Ohms ±1%, 0.25W), matching package designation (1206), and equivalent operating temperature range (-55°C ~ 155°C). Physical dimensions are within acceptable PCB assembly tolerances.

Q: What is the difference between CRCW1206105RFKEA and RC1206FR-07105RL?

A: Both are electrically equivalent. CRCW1206105RFKEA includes automotive AEC-Q200 qualification. RC1206FR-07105RL features moisture-resistant construction. Selection depends on application requirements and certification needs.

Q: Why is ERJ-8ENF1050V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While electrically and mechanically equivalent, it is reserved for legacy system support and replacement applications only.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Q: Do physical dimension variations affect PCB assembly compatibility?

A: Substitute parts exhibit minor dimensional variations within standard tolerances (length 0.122" to 0.126", width 0.061" to 0.063", height 0.024" to 0.028"). These variations remain within PCB assembly specifications and do not affect functional interchangeability.
