Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K2202FTP is determined by strict electrical and mechanical parameter matching. All substitute parts must satisfy the following mandatory criteria:

Electrical Parameters (Non-Negotiable):

• Resistance value: 22 kOhms
• Tolerance: ±1%
• Power rating: 0.25W minimum
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Parameters (Non-Negotiable):

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

Environmental Parameters (Acceptable if Equal or Superior):

• Moisture Sensitivity Level: MSL 1 or better
• RoHS compliance status
• REACH compliance status

All five substitute parts listed below meet these mandatory criteria. Differences in packaging format (Tape & Reel versus Cut Tape), manufacturer certifications (AEC-Q200 automotive qualification), and specific features (High Voltage, Moisture Resistant) represent secondary differentiators that do not affect core substitution eligibility but may influence selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

All five substitute parts are electrically and mechanically equivalent to the RMC1/8K2202FTP and satisfy the core substitution criteria. Selection among these alternatives should be based on the following factors:

For General-Purpose Applications with No Special Requirements: CRG1206F22K (TE Connectivity) is the primary recommendation. This part maintains Active product status, offers the highest inventory availability (22,423 pieces), and provides ROHS3 compliance. The CRG series (Neohm) represents a direct functional equivalent with identical electrical specifications and standard 1206 package dimensions.

For Automotive or High-Reliability Applications: RMCF1206FT22K0 (Stackpole Electronics) or KTR18EZPF2202 (Rohm Semiconductor) are recommended. Both parts carry AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability standards. RMCF1206FT22K0 maintains Active product status with 3,840 pieces in inventory. KTR18EZPF2202 adds High Voltage capability and offers 14,805 pieces in inventory, providing additional design margin for high-voltage circuit applications.

For Applications Requiring Enhanced Moisture Resistance: RC1206FR-0722KL (YAGEO) incorporates Moisture Resistant features in the RC_L series. This part is suitable for applications exposed to humid environments or requiring extended shelf life. Inventory availability is 2,300 pieces.

Parts to Avoid for New Designs: ERJ-8ENF2202V (Panasonic) carries "Not For New Designs" product status despite AEC-Q200 qualification and high inventory (56,312 pieces). This designation indicates the manufacturer is discontinuing this product line. Use only for replacement or repair of existing assemblies.

Packaging Considerations: RMC1/8K2202FTP, CRG1206F22K, KTR18EZPF2202, and RMCF1206FT22K0 are supplied in Tape & Reel format suitable for automated assembly. ERJ-8ENF2202V and RC1206FR-0722KL are supplied in Cut Tape & Digi-Reel format, which may require manual handling or alternative feeder compatibility depending on assembly equipment.

Frequently Asked Questions (FAQ)

Q1: Can I substitute ERJ-8ENF2202V for RMC1/8K2202FTP in new product designs?

A: No. Although ERJ-8ENF2202V meets all electrical and mechanical substitution criteria, Panasonic has designated this part as "Not For New Designs." This status indicates the manufacturer is phasing out this product line. For new designs, select from CRG1206F22K, KTR18EZPF2202, RC1206FR-0722KL, or RMCF1206FT22K0, all of which carry Active product status.

Q2: What is the difference between the 1206 package dimensions listed for different manufacturers?

A: All parts use the 1206 (3216 Metric) package standard. Minor dimensional variations exist within manufacturing tolerances: length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width ranges from 0.061" to 0.063" (1.55mm to 1.60mm), and height ranges from 0.025" to 0.028" (0.65mm to 0.70mm). These variations fall within standard PCB footprint tolerances and do not affect interchangeability.

Q3: Are all substitute parts RoHS3 compliant?

A: Four of the five substitute parts (CRG1206F22K, ERJ-8ENF2202V, KTR18EZPF2202, RC1206FR-0722KL, RMCF1206FT22K0) are explicitly ROHS3 compliant. The main part RMC1/8K2202FTP does not specify RoHS status in the provided data. If RoHS3 compliance is a design requirement, select from the four compliant alternatives.

Q4: Which substitute part offers the best inventory availability?

A: ERJ-8ENF2202V has the highest inventory at 56,312 pieces. However, due to its "Not For New Designs" status, CRG1206F22K is the recommended alternative for new designs, with 22,423 pieces available.

Q5: Do I need AEC-Q200 qualification for my application?

A: AEC-Q200 qualification is required only for automotive applications or systems subject to automotive reliability standards. Three substitute parts carry this certification: ERJ-8ENF2202V, KTR18EZPF2202, and RMCF1206FT22K0. For non-automotive applications, AEC-Q200 certification is not necessary, and CRG1206F22K or RC1206FR-0722KL are suitable alternatives.

Q6: What does "High Voltage" mean for KTR18EZPF2202?

A: The High Voltage feature indicates that KTR18EZPF2202 is rated for operation in high-voltage circuit environments. This part is suitable for applications where circuit voltages exceed standard levels. If your application does not involve high-voltage operation, this feature provides additional design margin but is not required for standard applications.

Q7: Can I use Cut Tape & Digi-Reel packaged parts in my automated assembly line?

A: Cut Tape & Digi-Reel format (ERJ-8ENF2202V and RC1206FR-0722KL) requires compatible feeder equipment. If your assembly line uses standard Tape & Reel feeders, select from RMC1/8K2202FTP, CRG1206F22K, KTR18EZPF2202, or RMCF1206FT22K0. Verify feeder compatibility with your equipment manufacturer before ordering alternative packaging formats.

Q8: Are all substitute parts rated for -55°C to 155°C operation?

A: Yes. All substitute parts and the main part RMC1/8K2202FTP are rated for the identical operating temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. Temperature performance is equivalent across all options.

Q9: What is the significance of "Moisture Resistant" in RC1206FR-0722KL?

A: The Moisture Resistant feature indicates enhanced protection against moisture absorption and environmental degradation. This is beneficial for applications exposed to high humidity, condensation, or extended storage in humid conditions. For standard indoor applications with controlled environmental conditions, this feature is not required.

Q10: Can I mix different substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing different manufacturers' parts in the same assembly is acceptable from a functional standpoint. However, for manufacturing traceability and quality control, it is standard practice to use a single part number per assembly revision unless explicitly documented otherwise in the design specification.
