Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4309R-101-221LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 220 Ohm
• Tolerance: ±2%
• Number of resistors: 8
• Power per element: 200mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Circuit type: Bussed
• Pin count: 9
• Package designation: 9-SIP
• Mounting type: Through Hole

The 4609X-101-221LF meets all electrical and mechanical specifications required for direct substitution. Differences in packaging format (bulk versus tube) and minor dimensional variations do not affect functional compatibility in circuit applications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the 4609X-101-221LF be used as a direct replacement for the 4309R-101-221LF?

A: Yes. Both parts are electrically and mechanically equivalent, featuring identical resistance values, tolerances, power ratings, temperature coefficients, and pin configurations. The primary difference is packaging format.

Q: What is the significance of the packaging difference between tube and bulk?

A: Packaging format affects handling, storage, and ordering quantities but does not impact electrical performance or circuit compatibility. Tube packaging is typically used for smaller quantities, while bulk packaging accommodates larger volume orders.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 4309R-101-221LF measures 0.884" L x 0.085" W with a maximum seated height of 0.195", while the 4609X-101-221LF measures 0.898" L x 0.098" W with a maximum seated height of 0.200". These variations remain within acceptable tolerances for standard through-hole PCB applications.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The 4309R-101-221LF is REACH Affected, while the 4609X-101-221LF is REACH Unaffected. Compliance requirements should be verified against specific application and regional regulations.

Q: What determines substitution eligibility for resistor network arrays?

A: Substitution is determined by equivalence in resistance value, tolerance, number of elements, power rating, temperature coefficient, operating temperature range, circuit topology, pin count, and package type. All these parameters must match for functional interchangeability.
