Substitute Part Grouping Explanation

Substitution eligibility for the 4814P-2-102LF is determined by strict equivalence in the following parameters:

• Resistance value: 1kΩ
• Tolerance: ±2%
• Number of resistors: 13
• Circuit type: Bussed
• Temperature coefficient: ±100ppm/°C
• Package / Case: 14-SOIC (0.220", 5.59mm Width)
• Number of pins: 14
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Variations permitted within substitution criteria include power per element ratings (when equal to or greater than the original specification), operating temperature range extensions, and packaging format differences (Tape & Reel versus Tube). All substitute parts maintain identical electrical performance and mechanical footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SOMC14011K00GEA (Vishay Dale) and 767141102GP (CTS Resistor Products) are qualified substitutes for the 4814P-2-102LF based on electrical and mechanical parameter equivalence.

SOMC14011K00GEA maintains identical power per element specification (80mW) and extends the operating temperature range to -55°C ~ 150°C, providing additional thermal margin for applications requiring extended temperature operation. This part is supplied in Tape & Reel format.

767141102GP provides an upgraded power per element rating of 100mW while maintaining the original operating temperature range of -55°C ~ 125°C. This increased power rating offers enhanced thermal headroom for designs operating at maximum current levels. This part is supplied in Tube packaging format.

All three parts maintain ROHS3 compliance, MSL Level 1 rating, and identical footprint geometry, ensuring direct mechanical and electrical interchangeability in 14-SOIC surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can SOMC14011K00GEA be used as a direct replacement for 4814P-2-102LF?

A: Yes. Both parts share identical resistance value (1kΩ), tolerance (±2%), number of resistors (13), circuit type (Bussed), temperature coefficient (±100ppm/°C), package geometry (14-SOIC), and pin count (14). The extended operating temperature range (-55°C ~ 150°C) of SOMC14011K00GEA is compatible with applications designed for the original -55°C ~ 125°C range.

Q: What is the difference between 767141102GP and the original 4814P-2-102LF?

A: The primary difference is the power per element rating: 767141102GP is rated at 100mW compared to 80mW for 4814P-2-102LF. All other electrical parameters and mechanical specifications are equivalent. The 100mW rating provides additional thermal capacity. Packaging format differs (Tube versus Tape & Reel).

Q: Are all three parts mechanically compatible with the same PCB footprint?

A: Yes. All three parts use the 14-SOIC (0.220", 5.59mm Width) package with identical pin count (14) and footprint dimensions (0.390" L x 0.220" W / 9.91mm x 5.59mm). Height variations are within acceptable assembly tolerances.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and are classified as Active product status. ECCN and HTSUS classifications are identical across all parts.

Q: Which substitute should be selected for high-temperature applications?

A: SOMC14011K00GEA supports operation to 150°C, providing the widest temperature margin. Selection depends on specific application temperature requirements and thermal design constraints.
