SMC Connector Plug 1002-1571-003 Equivalent & Substitute Parts

Part Overview

The Radiall USA 1002-1571-003 is an SMC connector plug with female socket configuration, designed for 50-ohm RF applications. This free-hanging, in-line connector features crimp termination for both center contact and shield, supporting frequencies up to 10 GHz. The part is currently active in production with 777 units in stock. Equivalent and substitute parts are identified to provide procurement flexibility, support supply chain continuity, and accommodate different termination requirements in system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1002-1571-003 is determined by the following critical parameters:

• Connector Style & Type: Must be SMC connector plug with female socket configuration
• Impedance: Must maintain 50-ohm characteristic impedance
• Mounting Configuration: Must be free-hanging, in-line design
• Frequency Capability: Must support operation up to 10 GHz minimum
• Operating Temperature: Must support -65°C to 165°C range
• Voltage Rating: Must meet or exceed 335 V
• Mating Cycles: Must support minimum 500 cycles
• Termination Compatibility: Contact and shield termination methods determine assembly compatibility

The substitute part 903-284P-52S (Amphenol RF) meets all core electrical and mechanical parameters. The primary difference is the contact termination method: the substitute uses solder termination instead of crimp. This represents a functional equivalent suitable for applications where solder assembly is preferred or required.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with current manufacturing status. The 1002-1571-003 (Radiall) carries RoHS compliance certification. The 903-284P-52S (Amphenol RF) carries ROHS3 compliance and REACH affected status, indicating compliance with current European environmental regulations.

Selection between these parts should be based on termination method requirements:

• 1002-1571-003: Select when crimp termination is specified or preferred for both center contact and shield
• 903-284P-52S: Select when solder termination is required for center contact assembly, with crimp shield termination

The insertion loss specification difference (0.25 dB vs. 0.3 dB) reflects measurement or design variation and does not indicate functional incompatibility in typical RF applications. Both parts support identical frequency, impedance, temperature, and voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can 903-284P-52S replace 1002-1571-003 in existing designs?

A: Yes, provided the assembly process accommodates solder termination instead of crimp termination. The electrical and mechanical specifications are equivalent. Cable compatibility includes RG-174, 179, 316 for the original part and RG-174, 188, 188A, 316, LMR-100, M17/119-RG174 for the substitute.

Q: What is the primary difference between these two parts?

A: The contact termination method. The 1002-1571-003 uses crimp termination; the 903-284P-52S uses solder termination. Shield termination is crimp for both. This affects assembly procedures but not RF performance or mechanical compatibility.

Q: Are both parts suitable for -65°C to 165°C operation?

A: Yes. Both parts specify identical operating temperature ranges and are rated for the same environmental conditions.

Q: What is the insertion loss difference between these connectors?

A: The 1002-1571-003 specifies 0.25 dB insertion loss; the 903-284P-52S specifies 0.3 dB. Both values are within acceptable ranges for SMC connectors in 50-ohm RF systems and do not indicate functional incompatibility.

Q: Are there packaging or quantity considerations?

A: The 1002-1571-003 is available in bulk packaging with 777 units in stock. The 903-284P-52S is available in bulk packaging with 1033 units in stock and includes 4-piece component sets (connector, contact, ferrule, insulator).

Q: Do both parts meet current compliance standards?

A: Yes. The 1002-1571-003 is RoHS Compliant. The 903-284P-52S is ROHS3 Compliant and REACH Affected, indicating compliance with current environmental regulations.
