Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3573FTP is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Resistance value: 357 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

All five substitute parts listed meet these mandatory parameters. Substitute parts may include additional features such as Automotive AEC-Q200 certification or moisture-resistant construction, which represent enhancements to the base specification and do not prevent substitution. Dimensional variations within the 1206 package specification are acceptable per industry standards.

Engineering Selection Recommendations

Primary Selection (Active Status):

For new designs and ongoing production, select from parts with Active product status:

• KTR18EZPF3573 (Rohm Semiconductor): Active status with Automotive AEC-Q200 certification and High Voltage features. 9,059 units in stock.
• RC1206FR-07357KL (YAGEO): Active status with Moisture Resistant construction. 18,728 units in stock. Highest inventory availability.
• RMCF1206FT357K (Stackpole Electronics Inc): Active status with Automotive AEC-Q200 certification. 2,332 units in stock.

Secondary Selection (Discontinued/Not For New Designs):

For replacement or legacy system support only:

• ERJ-8ENF3573V (Panasonic Electronic Components): Not For New Designs status. Automotive AEC-Q200 certified. 54,270 units in stock.
• MCR18ERTF3573 (Rohm Semiconductor): Discontinued at DiGi Electronics. 11,108 units in stock.

All substitute parts carry ROHS3 compliance and REACH Unaffected status, matching regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF3573V replace RMC1/8K3573FTP in new designs?

A: ERJ-8ENF3573V meets all electrical and mechanical specifications for direct substitution. However, its product status is listed as "Not For New Designs," indicating the manufacturer recommends against use in new applications. For new designs, select from Active status alternatives: KTR18EZPF3573, RC1206FR-07357KL, or RMCF1206FT357K.

Q: What is the difference between standard and Automotive AEC-Q200 versions?

A: KTR18EZPF3573 and RMCF1206FT357K include Automotive AEC-Q200 certification, indicating qualification for automotive applications with enhanced reliability testing. Standard versions (MCR18ERTF3573, RC1206FR-07357KL) meet general industrial specifications. Both types are electrically and mechanically equivalent for non-automotive applications.

Q: Are dimensional variations between substitute parts significant?

A: All parts conform to the 1206 (3216 Metric) package standard. Dimensional variations (length 0.120" to 0.126", height 0.025" to 0.028") fall within standard package tolerances and do not affect PCB layout or reflow soldering processes.

Q: Which substitute part has the highest inventory availability?

A: RC1206FR-07357KL (YAGEO) has 18,728 units in stock, the highest among all substitutes. This part is Active status and includes Moisture Resistant construction.

Q: Is RoHS3 compliance required for all substitutes?

A: All substitute parts listed are ROHS3 Compliant. The main part number (RMC1/8K3573FTP) does not specify RoHS status in the provided data. For applications requiring RoHS certification, all listed substitutes meet this requirement.

Q: Can MCR18ERTF3573 be used despite discontinued status?

A: MCR18ERTF3573 is discontinued at DiGi Electronics but meets all electrical and mechanical specifications. It remains suitable for replacement in existing systems or legacy applications where inventory is available (11,108 units in stock). For new production, select Active status alternatives.
