Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4641FTP is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 4.64 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 type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Environmental & Compliance Parameters (Must Match or Exceed):

• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging format: Tape & Reel (TR)

All substitute parts listed meet or exceed these parameters. Variations in physical dimensions (length, width, height) within the 1206 package specification and differences in product status or certifications do not affect functional substitutability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RMC1/8K4641FTP): Select the original Kamaya part for new designs when supply is available. Active product status ensures long-term availability and manufacturer support.

Secondary Selection (RC1206FR-074K64L - YAGEO): This substitute is recommended for general-purpose applications requiring active product status and moisture-resistant construction. YAGEO RC_L series offers equivalent electrical performance with ROHS3 compliance and active manufacturing status. Physical dimensions remain within 1206 package specification.

Automotive Applications (ERJ-8ENF4641V or RMCF1206FT4K64): For designs requiring AEC-Q200 automotive qualification, select either the Panasonic ERJ-8ENF4641V or Stackpole RMCF1206FT4K64. Both parts meet automotive reliability standards. Note that ERJ-8ENF4641V carries "Not For New Designs" status; therefore, RMCF1206FT4K64 is preferred for new automotive designs due to active product status.

Inventory Considerations: YAGEO RC1206FR-074K64L offers the highest inventory availability (51,259 pieces), followed by Panasonic ERJ-8ENF4641V (88,750 pieces). Stackpole RMCF1206FT4K64 maintains lower inventory (7,756 pieces) but remains actively manufactured.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF4641V be used as a direct replacement for RMC1/8K4641FTP?

A: Yes. Both parts share identical electrical specifications (4.64 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package format (1206). The ERJ-8ENF4641V includes AEC-Q200 automotive certification as an additional feature. However, its "Not For New Designs" status should be considered for long-term production planning.

Q: What is the difference between RC1206FR-074K64L and RMC1/8K4641FTP?

A: Both parts are electrically and mechanically equivalent. RC1206FR-074K64L features moisture-resistant construction and ROHS3 compliance. Physical dimensions vary slightly within 1206 package tolerance (RC1206FR-074K64L: 3.10mm L x 1.60mm W vs. RMC1/8K4641FTP: 3.10mm L x 1.60mm W). Both maintain identical electrical performance.

Q: Are automotive-qualified versions available?

A: Yes. Both ERJ-8ENF4641V (Panasonic) and RMCF1206FT4K64 (Stackpole) carry AEC-Q200 certification. For new automotive designs, RMCF1206FT4K64 is recommended due to active product status.

Q: Do all substitute parts have the same MSL rating?

A: Yes. All listed parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts conform to 1206 (3216 Metric) package specification with 2 terminations. Tape & Reel packaging format is consistent across all parts, enabling direct substitution in automated assembly processes.

Q: What is the significance of "Not For New Designs" status on ERJ-8ENF4641V?

A: This designation indicates that while the part remains available, the manufacturer recommends against incorporating it into new product designs. Existing designs may continue using this part, but new designs should select RMCF1206FT4K64 (Stackpole) for automotive applications or RC1206FR-074K64L (YAGEO) for general applications.
