Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3322FTP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 33.2 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical & Package Equivalence Requirements:

• Package type: 1206 (3216 Metric) surface mount (exact match)
• Composition: Thick film (exact match)
• Number of terminations: 2 (exact match)
• Moisture sensitivity level: MSL 1 (exact match)

Compliance & Regulatory Equivalence:

• REACH Status: REACH Unaffected (all substitutes)
• ECCN: EAR99 (all substitutes)
• HTSUS: 8533.21.0030 (all substitutes)

All identified substitute parts meet these criteria and are therefore electrically, mechanically, and functionally equivalent to the RMC1/8K3322FTP.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

For general industrial and commercial applications, RC1206FR-0733K2L (YAGEO) and RMCF1206FT33K2 (Stackpole Electronics Inc) are recommended. Both parts carry Active product status, ROHS3 compliance, and demonstrate high inventory availability (17,993 and 248,178 units respectively). These parts provide direct functional equivalence with established supply chain reliability.

Automotive Applications:

For automotive circuit designs requiring AEC-Q200 qualification, KTR18EZPF3322 (Rohm Semiconductor) is the preferred substitute. This part combines Active product status with automotive-grade certification and high voltage capability. RMCF1206FG33K2 and RMCF1206FT33K2 (both Stackpole Electronics Inc) are alternative automotive-qualified options, with RMCF1206FT33K2 offering superior inventory depth (248,178 units).

Legacy Design Considerations:

ERJ-8ENF3322V (Panasonic Electronic Components) carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where original component compatibility is mandatory. This part retains full electrical and mechanical equivalence but is not recommended for new product development.

Compliance Assurance:

All substitute parts maintain REACH Unaffected status, EAR99 ECCN classification, and HTSUS code 8533.21.0030, ensuring regulatory compliance across international markets. ROHS3 compliance is confirmed for all active-status substitutes.

Frequently Asked Questions (FAQ)

Q: Can RMC1/8K3322FTP be directly replaced with any of the listed substitutes in existing circuit boards?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. They share identical resistance (33.2 kΩ), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct PCB substitution is supported without circuit redesign.

Q: What is the difference between RMCF1206FG33K2 and RMCF1206FT33K2?

A: Both parts are manufactured by Stackpole Electronics Inc and are electrically identical. The primary difference is inventory availability: RMCF1206FT33K2 has 248,178 units in stock compared to 11,080 units for RMCF1206FG33K2. Both carry Active product status and AEC-Q200 automotive qualification. Selection should be based on supply chain requirements and lead time considerations.

Q: Are the dimensional variations between parts significant for PCB layout?

A: Dimensional variations are minimal and do not affect PCB layout compatibility. The RMC1/8K3322FTP measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.025" max height. Substitute parts measure 0.126" L × 0.063" W (3.20mm × 1.60mm) with heights ranging from 0.026" to 0.028". These variations fall within standard 1206 package tolerances and do not require PCB redesign.

Q: Which substitute is best for new automotive designs?

A: KTR18EZPF3322 (Rohm Semiconductor) is the optimal choice for new automotive designs. It carries Active product status, AEC-Q200 certification, and includes high voltage capability. RMCF1206FT33K2 (Stackpole Electronics Inc) is an alternative with superior inventory availability and equivalent automotive qualification.

Q: What does "Not For New Designs" mean for ERJ-8ENF3322V?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part for new product designs. The part remains functionally equivalent and suitable for legacy system repairs or maintenance. For new designs, select from parts with Active status: KTR18EZPF3322, RC1206FR-0733K2L, RMCF1206FG33K2, or RMCF1206FT33K2.

Q: Are all substitutes ROHS3 compliant?

A: All substitute parts with Active product status (KTR18EZPF3322, RC1206FR-0733K2L, RMCF1206FG33K2, RMCF1206FT33K2) are ROHS3 compliant. ERJ-8ENF3322V also carries ROHS3 compliance. The original RMC1/8K3322FTP does not specify ROHS status in the provided data.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts, including the RMC1/8K3322FTP and all substitutes, support the identical operating temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient. They are interchangeable for high-temperature circuit applications within this specified range.
