Key Parameters

Substitute Part Grouping Explanation

The TM21R-5C-88-LP(50) by Hirose Electric Co Ltd qualifies as a substitute based on the following alignment of critical parameters:

• Connector Type & Port Configuration: Both parts are RJ45 modular connectors with single-port configuration
• Mechanical Compatibility: Both feature 90° right-angle orientation, through-hole mounting, and solder termination
• Electrical Protection: Both incorporate shielding with EMI finger design
• Material Specification: Both use copper alloy contacts with gold finish and PBT housing
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Functional Application: Both support Ethernet connectivity (10/100 Base-T for the main part; Cat5e for the substitute)

Parameter Comparison

Engineering Selection Recommendations

Both the 0875-1B1T-P1 and TM21R-5C-88-LP(50) meet the core electrical and mechanical requirements for RJ45 Ethernet connector applications. Selection between these parts should be based on:

• Thermal Environment: The TM21R-5C-88-LP(50) operates across a wider temperature range (-25°C to 80°C) compared to the 0875-1B1T-P1 (0°C to 70°C). Applications requiring extended low-temperature operation favor the Hirose part.
• Compliance Certification: Both parts maintain identical RoHS3 and REACH compliance status, suitable for regulated markets.
• Availability & Lead Time: Inventory levels differ between manufacturers; procurement strategy should account for supply chain requirements.
• Series Continuity: The 0875-1B1T-P1 belongs to the MagJack® series, while the substitute is part of the TM21R series. Design continuity with existing component families may influence selection.

Frequently Asked Questions (FAQ)

Q: Can the TM21R-5C-88-LP(50) directly replace the 0875-1B1T-P1 in existing designs?

A: Yes, provided the application does not require the specific LED color indicators (Orange, Green) present in the 0875-1B1T-P1. The TM21R-5C-88-LP(50) does not contain LED functionality. All other mechanical, electrical, and compliance parameters align for direct substitution.

Q: What is the difference between the number of cores per jack specification?

A: The 0875-1B1T-P1 specifies 5 cores per jack, while the TM21R-5C-88-LP(50) uses the standard 8p8c (8 position, 8 contact) RJ45 configuration. Both support Ethernet connectivity; the specification difference reflects manufacturer documentation conventions rather than functional incompatibility.

Q: Are there packaging differences between these parts?

A: The 0875-1B1T-P1 packaging is not specified in the provided data. The TM21R-5C-88-LP(50) is supplied in tray packaging. Confirm packaging requirements with your procurement process before finalizing substitution.

Q: Which part should be selected for applications operating below 0°C?

A: The TM21R-5C-88-LP(50) is rated for operation down to -25°C and is the appropriate choice for low-temperature environments. The 0875-1B1T-P1 is rated from 0°C minimum.

Q: Do both parts meet export control requirements?

A: Yes. Both parts are classified as EAR99 under U.S. export control regulations and carry identical HTSUS commodity codes (8536.69.4040), indicating equivalent trade classification.
