Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K3741FTP is determined by strict equivalence across the following parameters:

Core Electrical Parameters:

• Resistance value: 3.74 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Compliance & Regulatory:

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

All five substitute parts listed meet these core requirements. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and product status do not disqualify substitution eligibility when electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

Active Product Status Substitutes:

KTR18EZPF3741 (Rohm Semiconductor), RC1206FR-073K74L (YAGEO), and RMCF1206FT3K74 (Stackpole Electronics Inc) maintain Active product status. These parts are suitable for new designs and ongoing production. KTR18EZPF3741 includes Automotive AEC-Q200 and High Voltage features. RMCF1206FT3K74 includes Automotive AEC-Q200 qualification. RC1206FR-073K74L includes Moisture Resistant features.

Limited Availability Substitutes:

ERJ-8ENF3741V (Panasonic Electronic Components) carries "Not For New Designs" status and is suitable only for legacy system maintenance or replacement applications. MCR18ERTF3741 (Rohm Semiconductor) is listed as "Discontinued at DiGi Electronics" and should be used only when existing inventory is available and no other alternatives are acceptable.

Compliance Considerations:

All substitute parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. All parts share identical HTSUS classification (8533.21.0030).

Packaging Format Selection:

Five substitute parts are supplied in Tape & Reel (TR) format, matching the original RMC1/8K3741FTP packaging. MCR18ERTF3741 is supplied in Cut Tape (CT) & Digi-Reel® format, which may require different handling and assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF3741V be used in new designs?

A: No. ERJ-8ENF3741V carries "Not For New Designs" product status. This part is suitable only for replacement or maintenance of existing systems. For new designs, select from KTR18EZPF3741, RC1206FR-073K74L, or RMCF1206FT3K74.

Q: What is the difference between the substitute parts in terms of electrical performance?

A: All substitute parts are electrically identical to the RMC1/8K3741FTP. They share the same resistance value (3.74 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Electrical performance differences do not exist among these parts.

Q: Are there physical dimension differences between the substitute parts?

A: Minor physical dimension variations exist within the 1206 (3216 Metric) package specification. Length ranges from 0.120" to 0.126" (3.05mm to 3.20mm), width is consistently 0.061" to 0.063" (1.55mm to 1.60mm), and height ranges from 0.025" to 0.028" (0.65mm to 0.70mm). These variations are within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part has the highest current inventory availability?

A: ERJ-8ENF3741V (Panasonic) has the highest inventory at 61,804 pieces. However, due to its "Not For New Designs" status, RMCF1206FT3K74 (46,478 pieces) or RC1206FR-073K74L (33,170 pieces) are preferred for active projects.

Q: Do any substitute parts include automotive qualification?

A: Yes. KTR18EZPF3741 and RMCF1206FT3K74 both carry Automotive AEC-Q200 qualification. KTR18EZPF3741 additionally includes High Voltage features. These parts are suitable for automotive and high-reliability applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging supplies components on cut tape segments, typically used for lower-volume assembly or manual placement. MCR18ERTF3741 uses Cut Tape format; all other substitutes use Tape & Reel format.

Q: Can MCR18ERTF3741 be used despite being discontinued at DiGi Electronics?

A: MCR18ERTF3741 can be used if existing inventory is available from alternative distributors. However, long-term supply cannot be guaranteed. For ongoing production, select from parts with Active status: KTR18EZPF3741, RC1206FR-073K74L, or RMCF1206FT3K74.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are ROHS3 Compliant. The original RMC1/8K3741FTP does not specify RoHS status in the provided data.

Q: Which substitute part includes moisture-resistant features?

A: RC1206FR-073K74L (YAGEO) includes Moisture Resistant features. All parts, including the original RMC1/8K3741FTP, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.
