Substitute Part Grouping Explanation

Substitute parts for the RT1206CRE0722K1L are qualified based on the following criteria:

Electrical Compatibility:

• Identical resistance value: 22.1 kOhms
• Same power rating: 0.25W (1/4W)
• Thin film composition maintained
• Operating temperature range: -55°C to 155°C (minimum requirement)

Mechanical Compatibility:

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Regulatory & Environmental:

• ROHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

Substitutes may differ in tolerance specification and temperature coefficient, provided the tolerance is equal to or tighter than the original part. Automotive-qualified variants (AEC-Q200) are included where applicable.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD0722K1L (YAGEO): This substitute offers improved tolerance (±0.1% vs. ±0.25%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C) while maintaining identical package and power specifications. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB2212V (Panasonic): This substitute provides identical electrical performance to RT1206BRD0722K1L with the addition of AEC-Q200 automotive qualification. Selection is required for automotive applications or systems subject to automotive-grade reliability standards. Physical dimensions are within 1206 footprint tolerance (3.20mm L vs. 3.10mm L, 0.70mm H vs. 0.65mm H).

All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and active production status.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0722K1L directly replace RT1206CRE0722K1L?

A: Yes. Both parts share identical resistance value (22.1 kOhms), power rating (0.25W), package (1206), and operating temperature range (-55°C to 155°C). RT1206BRD0722K1L provides superior tolerance (±0.1%) and temperature coefficient (±25ppm/°C), making it a direct upgrade with no circuit redesign required.

Q: When should ERA-8AEB2212V be selected?

A: ERA-8AEB2212V is selected when AEC-Q200 automotive qualification is mandatory. This part meets automotive reliability and qualification standards while providing the same electrical performance as RT1206BRD0722K1L. Physical dimensions remain compatible with standard 1206 PCB footprints.

Q: Are there package compatibility concerns between these substitutes?

A: All three parts use the 1206 (3216 Metric) package with 2 terminations. ERA-8AEB2212V has slightly larger dimensions (3.20mm L × 1.60mm W × 0.70mm H vs. 3.10mm L × 1.60mm W × 0.65mm H for YAGEO parts). These variations remain within standard 1206 footprint tolerances and do not require PCB layout modifications.

Q: What is the tolerance difference impact?

A: RT1206CRE0722K1L has ±0.25% tolerance; both substitutes have ±0.1% tolerance. This means substitutes maintain resistance within a narrower range (±2.21 Ohms vs. ±5.525 Ohms at 22.1 kOhms nominal). Selection depends on circuit accuracy requirements.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant, have MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status.
