Substitute Part Grouping Explanation

Substitution eligibility for the 4311R-101-331 is determined by strict equivalence across the following critical parameters:

• Resistance value: 330 Ohm (exact match required)
• Tolerance: ±2% (exact match required)
• Number of resistors: 10 (exact match required)
• Circuit type: Bussed (exact match required)
• Power per element: 200mW (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Package type: 11-SIP (exact match required)
• Mounting type: Through Hole (exact match required)
• Pin count: 11 (exact match required)

The 4611X-101-331LF meets all substitution criteria and is classified as an equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

The 4611X-101-331LF is a direct functional equivalent to the 4311R-101-331 with identical electrical and mechanical specifications. Both parts are Active status products from Bourns Inc. and maintain equivalent performance across all critical operating parameters.

The primary distinction between these parts is regulatory compliance. The 4611X-101-331LF carries ROHS3 compliance and REACH Unaffected status, whereas the 4311R-101-331 is RoHS non-compliant and REACH Affected. Selection between these parts should be based on regulatory requirements applicable to the end application and target markets.

Both parts are available in stock with comparable inventory levels (653 units for 4311R-101-331 and 728 units for 4611X-101-331LF), supporting immediate procurement for either option.

Frequently Asked Questions (FAQ)

Q: Can the 4611X-101-331LF be used as a direct replacement for the 4311R-101-331?

A: Yes. The 4611X-101-331LF meets all electrical and mechanical substitution criteria. Both parts feature identical resistance values, tolerance, power ratings, temperature coefficients, and package configurations. Pin count and mounting type are equivalent.

Q: What is the difference between these two parts?

A: The primary differences are regulatory compliance certifications. The 4611X-101-331LF is ROHS3 compliant and REACH Unaffected, while the 4311R-101-331 is RoHS non-compliant and REACH Affected. Electrical performance and physical specifications are identical.

Q: Are there dimensional differences between the 4311R-101-331 and 4611X-101-331LF?

A: Minor dimensional variations exist. The 4311R-101-331 measures 1.084" L x 0.085" W (27.53mm x 2.16mm) with a maximum seated height of 0.195" (4.95mm). The 4611X-101-331LF measures 1.098" L x 0.098" W (27.89mm x 2.49mm) with a maximum seated height of 0.200" (5.08mm). These variations are within typical manufacturing tolerances for 11-SIP packages and do not affect functional compatibility in standard PCB layouts.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH compliance, the 4611X-101-331LF is the appropriate choice. For applications without these regulatory constraints, either part is functionally equivalent.

Q: Are both parts available for immediate shipment?

A: Yes. Both parts are classified as Active status with current inventory: 4311R-101-331 (653 units) and 4611X-101-331LF (728 units).
