Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LR1F4M7 are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Resistance value: 4.7 MOhms
• Tolerance: ±1%
• Power rating: 0.6W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Composition: Metal Film

Mechanical Compatibility Criteria:

• Package type: Axial
• Number of terminations: 2
• Through-hole configuration

Compliance Criteria:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99

The substitute parts MRS25000C4704FC100 and MRS25000C4704FCT00 meet all electrical and mechanical requirements for direct substitution. Physical dimensions vary slightly (0.098" Dia x 0.256" L versus 0.091" Dia x 0.244" L), which remains within acceptable tolerances for axial through-hole component placement in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

All three components—LR1F4M7, MRS25000C4704FC100, and MRS25000C4704FCT00—are Active product status and maintain identical electrical specifications. Selection between these parts is determined by availability, packaging format, and supply chain requirements.

LR1F4M7 (TE Connectivity): Supplied in Tape & Box (TB) packaging format. Current inventory: 842 pieces.

MRS25000C4704FC100 (Vishay): Supplied in Cut Tape (CT) packaging format. Current inventory: 3,335 pieces.

MRS25000C4704FCT00 (Vishay): Supplied in Cut Tape (CT) packaging format. Current inventory: 19,647 pieces.

All parts satisfy ROHS3 compliance and REACH unaffected requirements. Component selection should be based on packaging compatibility with assembly equipment and procurement lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C4704FC100 or MRS25000C4704FCT00 be used as direct replacements for LR1F4M7?

A: Yes. Both Vishay parts are direct electrical and mechanical equivalents. All critical parameters—resistance, tolerance, power rating, temperature coefficient, and operating temperature range—are identical. The components are functionally interchangeable in axial through-hole applications.

Q: What is the difference between MRS25000C4704FC100 and MRS25000C4704FCT00?

A: Both parts are identical in electrical specifications and physical dimensions. The difference lies in packaging format designation within the Vishay product line. Both are supplied in Cut Tape (CT) format and are suitable for automated assembly processes.

Q: Are there dimensional differences between the main part and substitutes?

A: Minor dimensional variations exist. The LR1F4M7 measures 0.091" Dia x 0.244" L (2.30mm x 6.20mm), while both Vishay substitutes measure 0.098" Dia x 0.256" L (2.50mm x 6.50mm). These differences remain within acceptable tolerances for standard PCB through-hole layouts and do not affect electrical performance or mechanical fit in typical applications.

Q: Do all parts meet the same compliance standards?

A: Yes. LR1F4M7, MRS25000C4704FC100, and MRS25000C4704FCT00 are all ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts satisfy identical regulatory requirements.

Q: Which packaging format should be selected for high-volume assembly?

A: Cut Tape (CT) packaging is standard for automated pick-and-place assembly operations. Both Vishay substitutes (MRS25000C4704FC100 and MRS25000C4704FCT00) are supplied in CT format. Tape & Box (TB) packaging for the LR1F4M7 is suitable for manual assembly or lower-volume applications.
