Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RM12F20R0CT are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 20 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All substitute parts listed meet these core requirements. Variations in packaging format (Tape & Reel versus Cut Tape), minor dimensional tolerances, and additional features (such as Automotive AEC-Q200 certification or High Voltage rating) do not disqualify parts from substitution eligibility when the primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The KTR18EZPF20R0 (Rohm Semiconductor), RC1206FR-0720RL (YAGEO), and RMCF1206FT20R0 (Stackpole Electronics Inc) are all classified as Active product status, indicating ongoing manufacturer support and availability. These parts are suitable for new designs and production applications.

Secondary Selection (Legacy Status): The ERJ-8ENF20R0V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. This part remains functionally equivalent but is intended for legacy system support and replacement applications only.

Compliance Alignment: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory alignment with the original RM12F20R0CT specification.

Automotive Applications: The KTR18EZPF20R0, ERJ-8ENF20R0V, and RMCF1206FT20R0 include Automotive AEC-Q200 certification. The KTR18EZPF20R0 additionally features High Voltage capability. These certifications do not restrict use in non-automotive applications and provide enhanced reliability qualification for demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the RM12F20R0CT be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts meet the core electrical specifications (20 Ohms ±1%, 0.25W), mechanical package requirements (1206 / 3216 Metric), and compliance standards (ROHS3, MSL 1) of the RM12F20R0CT. Direct substitution is permissible at the component level.

Q: What is the difference between Active and "Not For New Designs" product status?

A: Active status indicates the manufacturer continues production and supports the part for new applications. "Not For New Designs" status indicates the manufacturer has discontinued active development but maintains limited availability for legacy system support. For new designs, Active status parts are preferred.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within the 1206 package specification. The RM12F20R0CT and RC1206FR-0720RL specify 0.122" length, while KTR18EZPF20R0, ERJ-8ENF20R0V, and RMCF1206FT20R0 specify 0.126" length. Height-seated maximum values range from 0.026" to 0.028". These variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What is the significance of Automotive AEC-Q200 certification on substitute parts?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. This certification is optional for general-purpose applications but provides enhanced reliability assurance. Parts with AEC-Q200 certification can be used in non-automotive applications without restriction.

Q: Does the High Voltage feature on the KTR18EZPF20R0 affect substitution compatibility?

A: No. High Voltage capability is an additional feature that does not restrict the part's use in standard applications. The KTR18EZPF20R0 remains fully compatible with circuits designed for the RM12F20R0CT.

Q: What packaging formats are available for these substitute parts?

A: The RC1206FR-0720RL is supplied in Cut Tape (CT) & Digi-Reel® format. The KTR18EZPF20R0, ERJ-8ENF20R0V, and RMCF1206FT20R0 are supplied in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and does not affect electrical or mechanical compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the RM12F20R0CT specification and ensuring regulatory alignment for applications subject to RoHS directives.
