Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the 4606X-102-153 is determined by the following critical parameters: resistance value (15kΩ), tolerance (±2%), circuit configuration (isolated), number of resistors (3), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), and package format (6-SIP through-hole). All identified substitutes maintain these core electrical specifications.

The substitute parts are grouped into two categories based on product status and compliance:

Active Bourns 4300R Series: The 4306R-102-153 and 4306R-102-153LF represent direct functional replacements from Bourns' active product line. Both maintain identical electrical performance with minor dimensional variations and improved compliance certifications.

Active CTS Alternative: The CTS 77063153P provides equivalent electrical functionality with identical resistance, tolerance, and temperature characteristics. This part operates at reduced power per element (100mW versus 300mW), which is acceptable for applications not requiring maximum power dissipation.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Bourns 4306R-102-153LF

The 4306R-102-153LF is the preferred substitute for new designs and production transitions. This part maintains full electrical equivalence with the 4606X-102-153 while offering ROHS3 compliance and active product status. The LF designation indicates lead-free construction, aligning with current manufacturing standards. Dimensional differences are negligible for through-hole applications.

Secondary Recommendation: Bourns 4306R-102-153

The 4306R-102-153 (non-LF variant) provides identical electrical performance and active status. Selection of this part depends on specific manufacturing or supply chain requirements where the non-lead-free version is preferred. RoHS non-compliance should be evaluated against application regulatory requirements.

Alternative Recommendation: CTS 77063153P

The CTS 77063153P serves as a cross-manufacturer alternative with full electrical compatibility. This part is suitable for applications where power dissipation per element does not exceed 100mW. ROHS3 compliance and REACH unaffected status provide regulatory advantages. Dimensional similarity ensures mechanical compatibility in through-hole layouts.

Frequently Asked Questions (FAQ)

Q: Can the 4306R-102-153LF directly replace the 4606X-102-153 in existing designs?

A: Yes. The 4306R-102-153LF maintains identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating range. Through-hole package compatibility is confirmed. Dimensional variations (0.584" L × 0.085" W versus 0.598" L × 0.098" W) are within acceptable tolerances for standard PCB layouts.

Q: What is the significance of the LF designation in 4306R-102-153LF?

A: LF indicates lead-free construction, compliant with ROHS3 standards. This designation reflects modern manufacturing practices and regulatory compliance requirements. The electrical performance is identical to the non-LF variant.

Q: Is the CTS 77063153P suitable for all applications using the 4606X-102-153?

A: The CTS part is suitable for applications where power dissipation per element does not exceed 100mW. The 4606X-102-153 is rated for 300mW per element. Applications requiring maximum power handling should use the Bourns 4306R series substitutes.

Q: Are there dimensional concerns when substituting these parts?

A: All substitute parts use the 6-SIP through-hole package with compatible pin configurations. Dimensional variations are minor and do not affect standard PCB footprints. Height differences (4.95mm to 5.08mm) are negligible for typical circuit board spacing.

Q: What compliance differences exist between the substitute options?

A: The 4306R-102-153LF and 77063153P are ROHS3 compliant, while the 4306R-102-153 is not. The 4306R series (both variants) are REACH affected, while the CTS part is REACH unaffected. Selection should align with end-product regulatory requirements.
