Key Parameters

Substitute Part Grouping Explanation

Substitution for the 4606X-102-152 is determined by the following criteria:

Primary Substitution Criteria:

• Resistance value: 1.5k Ohm
• Tolerance: ±2%
• Circuit configuration: Isolated 3-resistor network
• Power rating: 300mW per element
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 6-SIP through-hole configuration
• Pin count: 6 pins

Substitute Categories:

1. Direct Equivalent (Same Series): 4606X-102-152LF — Identical electrical specifications, same 4600X series, active product status with improved RoHS3 compliance.

2. Cross-Series Alternatives (4300R Series): 4306R-102-152 and 4306R-102-152LF — Different product series with identical electrical parameters but minor dimensional variations and different resistor-ratio-drift specification (50ppm/°C vs. not specified for main part).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production: Select 4606X-102-152LF as the primary substitute. This part maintains identical electrical specifications and mechanical compatibility with the obsolete 4606X-102-152 while offering ROHS3 compliance and active product status. The bulk packaging format supports standard manufacturing workflows.

For Legacy System Maintenance: The 4306R-102-152LF provides a secondary alternative with ROHS3 compliance and active status. The 4300R series exhibits minor dimensional differences (0.584" L x 0.085" W vs. 0.598" L x 0.098" W) and includes resistor-ratio-drift specification of 50ppm/°C. Verify mechanical fit within existing PCB layouts before implementation.

Compliance Considerations: All active substitute parts (4606X-102-152LF and 4306R-102-152LF) meet ROHS3 requirements. The 4306R series is REACH Affected; verify regulatory requirements for your application region.

Frequently Asked Questions (FAQ)

Q: Can 4606X-102-152LF directly replace 4606X-102-152 without PCB modification? A: Yes. The 4606X-102-152LF maintains identical electrical specifications, pin configuration, and mechanical dimensions. No PCB layout changes are required.

Q: What are the dimensional differences between 4606X and 4306R series? A: The 4606X-102-152 measures 0.598" L x 0.098" W x 0.200" H (seated). The 4306R series measures 0.584" L x 0.085" W x 0.195" H (seated). These differences may affect PCB routing and component spacing in dense layouts.

Q: Does the 4306R series resistor-ratio-drift specification affect substitution? A: The 4306R series specifies 50ppm/°C resistor-ratio-drift, while the main part does not specify this parameter. Applications requiring matched resistor tracking over temperature should evaluate this specification against circuit requirements.

Q: Are all substitute parts available in the same packaging formats? A: No. The 4606X-102-152LF is supplied in bulk packaging, while 4306R variants are supplied in tube packaging. Verify packaging compatibility with your assembly process.

Q: Which substitute offers the best compliance profile? A: Both 4606X-102-152LF and 4306R-102-152LF are ROHS3 compliant. The 4606X-102-152LF is REACH Unaffected, while the 4306R series is REACH Affected. Select based on your regulatory jurisdiction requirements.
