Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 51426-5 is based on strict electrical and mechanical parameter alignment. The substitute part 5051426-5 maintains identical specifications across all critical parameters that define functional compatibility:

Core Substitution Criteria:

• Connector style (SHV) and type (Plug, Female Socket) remain unchanged
• Contact and shield termination methods (Crimp) are identical
• Impedance classification (Non-Constant) is preserved
• Mounting configuration (Free Hanging In-Line) is maintained
• Fastening mechanism (Bayonet Lock) is consistent
• Operating temperature range (-65°C ~ 200°C) is identical
• Voltage rating (5000 V) is unchanged
• Mating cycle rating (500) is identical
• Dielectric material (PTFE) and center contact plating (Gold) are preserved
• Cable group compatibility includes all original groups (RG-59, 59A, 59B, 62, 62A, 62B) with extended support for RG-124, 140, and 210

The primary distinction is product status: 51426-5 is obsolete, while 5051426-5 is active and RoHS compliant, making it the appropriate selection for new designs and ongoing production requirements.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5051426-5 is the appropriate selection for applications currently using or requiring the 51426-5 connector. The following factors support this substitution:

Product Status: The original part 51426-5 is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute 5051426-5 maintains active production status, ensuring reliable supply chain access and long-term component availability.

Regulatory Compliance: The substitute part 5051426-5 is RoHS compliant, meeting current environmental and hazardous substance restrictions. The original part carries non-compliant status. For applications subject to RoHS requirements or future regulatory transitions, the substitute part satisfies compliance obligations.

REACH Status: The substitute part carries defined REACH status (REACH Affected), providing clear regulatory documentation. The original part lists vendor-undefined REACH status, creating uncertainty in regulatory compliance verification.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute, including connector style, termination methods, impedance classification, operating temperature range, voltage rating, and mating cycle specifications. Cable group compatibility is expanded in the substitute part to include RG-124, 140, and 210 in addition to the original RG-59 series cables.

Packaging: The substitute part is supplied in bulk packaging, suitable for production environments and inventory management.

Frequently Asked Questions (FAQ)

Q: Can 5051426-5 be used as a direct replacement for 51426-5 in existing applications?

A: Yes. The substitute part 5051426-5 maintains identical electrical and mechanical specifications across all critical parameters. Connector style, termination methods, impedance, operating temperature range, voltage rating, and mating cycle specifications are unchanged. Physical compatibility and functional performance are preserved.

Q: What cable types are compatible with the substitute part 5051426-5?

A: The substitute part 5051426-5 is compatible with RG-59, 59A, 59B, 62, 62A, 62B, 124, 140, and 210 cable groups. This represents an expansion of the original part's cable compatibility, which supported RG-59, 59A, 59B, 62, 62A, and 62B only.

Q: Why is the original part 51426-5 classified as obsolete?

A: The 51426-5 is listed as obsolete, indicating that TE Connectivity AMP Connectors has discontinued manufacturing. The active substitute 5051426-5 provides continued access to equivalent functionality with current production support.

Q: What is the significance of RoHS compliance in the substitute part?

A: The substitute part 5051426-5 is RoHS compliant, meeting Restriction of Hazardous Substances regulations. The original part is non-compliant. RoHS compliance is required for many applications, particularly in consumer electronics and regulated industries. The substitute part satisfies these regulatory requirements.

Q: Are the operating temperature and voltage specifications identical between the two parts?

A: Yes. Both parts operate across the temperature range of -65°C to 200°C and maintain a voltage rating of 5000 V. Mating cycle specifications are also identical at 500 cycles.

Q: What is the difference in packaging between the original and substitute parts?

A: The original part 51426-5 packaging is not specified. The substitute part 5051426-5 is supplied in bulk packaging, suitable for production and inventory applications.

Q: Does the substitute part maintain the same dielectric material and contact plating?

A: Yes. Both parts use polytetrafluoroethylene (PTFE) as the dielectric material and gold plating for the center contact. Housing and body finish are silver in both parts.

Q: What inventory levels are available for each part?

A: The original part 51426-5 has 1056 pieces in stock. The substitute part 5051426-5 has 1520 pieces in stock, providing greater availability for procurement.

Q: Are there any differences in the connector's mechanical fastening system?

A: No. Both parts use bayonet lock fastening and maintain identical mounting configuration as free hanging in-line connectors. The mechanical interface remains unchanged.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements.
