Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3012FTP is determined by strict compliance with the following parameters:

Critical Matching Parameters:

• Resistance value: 30.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Package: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these critical parameters. Dimensional variations within supplier tolerances and additional certifications (such as AEC-Q200 automotive qualification) do not disqualify a part from substitution eligibility, as these represent enhanced specifications rather than deviations from core electrical performance.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Status Applications:

RC1206FR-0730K1L (YAGEO) is the primary recommended substitute. This part maintains Active product status, carries ROHS3 compliance, and provides the highest inventory availability (134,525 pcs). It is suitable for all general-purpose applications where the RMC1/8K3012FTP is specified.

RMCF1206FG30K1 and RMCF1206FT30K1 (both Stackpole Electronics Inc) are secondary alternatives. Both maintain Active product status and include AEC-Q200 automotive qualification, making them suitable for applications requiring automotive-grade reliability. Inventory levels are adequate (9,804 pcs and 18,085 pcs respectively).

For Automotive or High-Reliability Applications:

RMCF1206FG30K1 or RMCF1206FT30K1 are preferred due to AEC-Q200 certification. These parts exceed the base specification of RMC1/8K3012FTP while maintaining full electrical and mechanical compatibility.

Not Recommended for New Designs:

ERJ-8ENF3012V (Panasonic) carries "Not For New Designs" product status. While electrically and mechanically equivalent and AEC-Q200 qualified, this designation indicates the manufacturer is discontinuing this product line. Use only for replacement or maintenance of existing designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1206FR-0730K1L for RMC1/8K3012FTP in my circuit?

A: Yes. RC1206FR-0730K1L meets all critical electrical parameters (30.1 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and package specifications (1206 thick film). Both components are MSL 1 rated and functionally interchangeable at the circuit level.

Q: What is the difference between RMCF1206FG30K1 and RMCF1206FT30K1?

A: Both parts are manufactured by Stackpole Electronics Inc and are electrically identical (30.1 kOhms ±1%, 0.25W, AEC-Q200). The difference lies in internal construction or manufacturing process designation (FG vs FT suffix). Both are suitable substitutes for RMC1/8K3012FTP.

Q: Why is ERJ-8ENF3012V marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued or is phasing out this product line. While the part remains functionally equivalent and AEC-Q200 qualified, it should not be selected for new circuit designs. Use only for replacement of existing assemblies.

Q: Are there dimensional differences between these substitute parts?

A: Minor dimensional variations exist within supplier tolerances. RMC1/8K3012FTP and RC1206FR-0730K1L are both 0.122" L x 0.063" W (3.10mm x 1.60mm). Panasonic ERJ-8ENF3012V and Stackpole RMCF series are 0.126" L x 0.063" W (3.20mm x 1.60mm). Height differences are similarly minor (0.025" to 0.028" maximum seated height). These variations are within standard PCB design tolerances and do not affect substitutability.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All listed substitute parts carry MSL 1 (Unlimited) rating, identical to RMC1/8K3012FTP. No special moisture handling or baking procedures are required for any of these components.

Q: Which substitute offers the best inventory availability?

A: RC1206FR-0730K1L (YAGEO) provides the highest inventory level at 134,525 pcs in stock, followed by ERJ-8ENF3012V (Panasonic) at 48,636 pcs and RMCF1206FT30K1 (Stackpole) at 18,085 pcs.
