RMC1/8K7683FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K7683FTP is a 768 kOhms ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package. This component is classified as Active product status with 1065 pieces currently in stock inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design specifications allow for alternative qualified sources meeting identical electrical and mechanical parameters. All substitute parts listed maintain the same resistance value, tolerance, power rating, package configuration, and operating temperature range as the main part.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RMC1/8K7683FTP is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance: 768 kOhms
• Tolerance: ±1%
• Power Rating: 0.25W (1/4W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 1206 (3216 Metric)
• Number of Terminations: 2
• Composition: Thick Film

Environmental Parameters (Must Match Exactly):

• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts listed (ERJ-8ENF7683V, RC1206FR-07768KL, RMCF1206FT768K) meet these exact specifications and are therefore direct functional equivalents. Differences in physical dimensions (length and height) within the 1206 package tolerance, product status classifications, and optional certifications (such as AEC-Q200) do not affect substitution validity for applications where these specifications are not contractually required.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RMC1/8K7683FTP): The Kamaya Inc. RMC1/8K7683FTP is the specified main part with Active product status and 1065 pieces in current inventory. This part is suitable for new designs and ongoing production.

Secondary Selection (RC1206FR-07768KL): The YAGEO RC1206FR-07768KL maintains Active product status with 15399 pieces in inventory. This part includes moisture-resistant features and ROHS3 compliance. Selection is appropriate when YAGEO supply chain preference is established or when moisture-resistant composition is contractually specified.

Tertiary Selection (RMCF1206FT768K): The Stackpole Electronics Inc. RMCF1206FT768K is Active with AEC-Q200 automotive qualification and 1317 pieces in inventory. This part is suitable for applications requiring automotive-grade component certification.

Not Recommended for New Designs (ERJ-8ENF7683V): The Panasonic Electronic Components ERJ-8ENF7683V carries "Not For New Designs" product status despite AEC-Q200 qualification and high inventory (41721 pieces). This designation indicates manufacturer discontinuation trajectory. Use only for legacy design maintenance or when existing design documentation explicitly specifies this part number.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF7683V be used as a direct replacement for RMC1/8K7683FTP?

A: Electrically and mechanically, yes. The ERJ-8ENF7683V meets all core specifications: 768 kOhms ±1%, 0.25W, 1206 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. However, the "Not For New Designs" status indicates Panasonic is phasing out this product line. For new designs, RC1206FR-07768KL or RMCF1206FT768K are preferred alternatives.

Q: What is the difference between the physical dimensions listed for each part?

A: All parts are 1206 (3216 Metric) package classification. Minor dimensional variations (length 0.122" to 0.126", height 0.025" to 0.028") fall within standard 1206 package tolerances and do not affect PCB footprint compatibility or electrical performance.

Q: Are all substitute parts RoHS compliant?

A: ERJ-8ENF7683V, RC1206FR-07768KL, and RMCF1206FT768K are all ROHS3 compliant. The main part RMC1/8K7683FTP does not specify RoHS status in available documentation. Verify RoHS compliance requirements with your procurement or design specifications.

Q: Which substitute part should be selected for automotive applications?

A: RMCF1206FT768K carries AEC-Q200 automotive qualification rating. ERJ-8ENF7683V also includes AEC-Q200 but is marked "Not For New Designs." For new automotive designs, RMCF1206FT768K is the appropriate selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts share identical 1206 package footprints, two-terminal configuration, and electrical specifications. No PCB layout modifications are required for substitution.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage, handling, or assembly. All listed parts carry this same MSL rating.
