Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SIL09E103G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10k Ohm
• Tolerance: ±2%
• Number of resistors: 8
• Power per element: 200mW
• Circuit type: Bussed
• Package type: 9-SIP
• Number of pins: 9
• Mounting type: Through Hole
• Operating temperature range: -55°C to 125°C

The substitute part 4609X-101-103LF meets all mandatory matching parameters. Secondary parameters such as temperature coefficient, RoHS compliance status, and REACH classification may differ between the main part and substitute but do not affect functional substitution when the mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

SIL09E103G (TE Connectivity Passive Product): This part is suitable for applications where RoHS non-compliance is acceptable or where legacy design requirements specify TE Connectivity components. The part is active in production with established supply availability.

4609X-101-103LF (Bourns Inc.): This substitute part is suitable for applications requiring ROHS3 compliance. The Bourns component offers improved temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), providing superior stability across the operating temperature range. Physical dimensions are equivalent within manufacturing tolerances. Both parts are active in production and support equivalent circuit functionality.

Selection between these parts should be based on compliance requirements, supply chain preferences, and temperature stability specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the 4609X-101-103LF directly replace the SIL09E103G in existing designs?

A: Yes. Both parts share identical resistance value, tolerance, element count, power rating, pin configuration, package type, and operating temperature range. Physical dimensions are equivalent within standard manufacturing tolerances. Direct substitution is supported at the circuit level.

Q: What is the significance of the temperature coefficient difference between these parts?

A: The SIL09E103G has a temperature coefficient of ±200ppm/°C, while the 4609X-101-103LF has ±100ppm/°C. The lower temperature coefficient of the Bourns part indicates superior resistance stability across temperature variations. For applications with stringent temperature stability requirements, the 4609X-101-103LF provides enhanced performance.

Q: Are there PCB layout considerations when substituting between these parts?

A: No. Both parts use identical 9-SIP through-hole packaging with equivalent physical dimensions (22.86mm x 2.50mm for TE Connectivity; 22.81mm x 2.49mm for Bourns). Footprint compatibility is maintained, and no PCB redesign is required.

Q: What is the difference in RoHS compliance between these parts?

A: The SIL09E103G is RoHS non-compliant, while the 4609X-101-103LF is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the Bourns part satisfies compliance mandates.

Q: Are both parts currently available in production?

A: Yes. Both the SIL09E103G and 4609X-101-103LF are active products in production. The SIL09E103G has 1159 pieces in stock, and the 4609X-101-103LF has 4184 pieces in stock.

Q: Do these parts have different moisture sensitivity levels?

A: The SIL09E103G has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The 4609X-101-103LF has MSL Not Applicable, indicating no moisture sensitivity classification. Both parts are suitable for standard storage and handling conditions.
