Substitute Part Grouping Explanation

Substitution of the SIL09E104J is determined by strict equivalence in the following parameters:

• Resistance Value: 100k Ohm (exact match required)
• Number of Resistors: 8 elements (exact match required)
• Circuit Configuration: Bussed topology (exact match required)
• Package Type: 9-SIP form factor (exact match required)
• Pin Count: 9 pins (exact match required)
• Power Rating: 200mW per element (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Technology: Through-hole (exact match required)

The Bourns 4609X-101-104LF satisfies all mandatory equivalence criteria. Secondary improvements in tolerance (±2% versus ±5%) and temperature coefficient (±100ppm/°C versus ±200ppm/°C) represent enhanced performance characteristics that do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The 4609X-101-104LF from Bourns Inc. is the direct equivalent for the obsolete SIL09E104J. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Bourns part maintains active product status, ensuring continued availability and supply chain reliability.

The 4609X-101-104LF provides improved tolerance specification (±2% versus ±5%) and superior temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), delivering enhanced precision without requiring circuit redesign. All mechanical and electrical parameters remain identical, enabling direct pin-compatible substitution in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 4609X-101-104LF replace the SIL09E104J in existing designs?

A: Yes. The 4609X-101-104LF is pin-compatible and functionally equivalent. Both components feature identical 9-SIP package geometry, 9-pin configuration, 100k Ohm resistance, 8-resistor bussed topology, and 200mW power rating per element.

Q: What are the dimensional differences between these parts?

A: Dimensions are functionally equivalent. The SIL09E104J measures 0.900" L × 0.098" W (22.86mm × 2.50mm) with 0.200" maximum seated height. The 4609X-101-104LF measures 0.898" L × 0.098" W (22.81mm × 2.49mm) with identical 0.200" maximum seated height. These minor variations do not affect PCB layout or mechanical fit.

Q: Does the improved tolerance of the 4609X-101-104LF affect circuit compatibility?

A: No. The tighter ±2% tolerance of the 4609X-101-104LF is a performance enhancement that maintains backward compatibility. Circuits designed for the ±5% tolerance of the SIL09E104J operate within specification with the improved tolerance of the substitute part.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the SIL09E104J and 4609X-101-104LF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in all specified applications.

Q: Why is the SIL09E104J classified as obsolete?

A: The SIL09E104J has been discontinued by TE Connectivity. The 4609X-101-104LF from Bourns maintains active product status and serves as the recommended equivalent for new designs and component replacement.
