MMCX Connector Jack 135-3302-401 Equivalent & Substitute Parts

Part Overview

The Cinch Connectivity Solutions 135-3302-401 is an MMCX connector jack designed for RF coaxial applications requiring 50-ohm impedance. This female socket connector features panel mount installation with bulkhead front-side nut fastening and supports both crimp and solder contact termination methods. The connector is rated for frequencies up to 6 GHz and operates across a temperature range of -55°C to 155°C. As an active product with RoHS compliance and unlimited moisture sensitivity rating, this connector serves as a standard component in RF signal distribution systems. Equivalent alternatives exist to accommodate different termination preferences and supply chain requirements.

Termination Difference: The primary distinction between these parts is the contact termination method. The 135-3302-401 supports both crimp and solder termination, while the 262120 is configured for solder termination only. This difference does not affect electrical or mechanical compatibility when solder termination is the intended assembly method.

Parameter Comparison

Engineering Selection Recommendations

Both connectors maintain active product status and meet current regulatory compliance requirements. The Cinch 135-3302-401 carries RoHS compliance certification, while the Amphenol RF 262120 meets the more recent ROHS3 standard and is REACH-affected, indicating compliance with additional European regulatory frameworks.

Selection between these parts should be based on termination method requirements. If crimp termination is necessary, the 135-3302-401 is the appropriate choice. If solder termination is acceptable or preferred, the 262120 provides equivalent electrical and mechanical performance with enhanced regulatory compliance documentation.

Both parts support the same cable groups (RG-178, 196 series), operate at identical impedance and frequency specifications, and maintain equivalent mechanical durability ratings. The choice between bulk and bag packaging should align with assembly workflow and inventory management practices.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 262120 replace the Cinch 135-3302-401 in existing designs?

A: Yes, provided the design uses solder termination for the contact connection. Both connectors share identical electrical specifications (50 ohms, 6 GHz maximum frequency), mechanical mounting configurations (panel mount bulkhead), and physical dimensions. The primary consideration is termination method compatibility.

Q: What is the difference between crimp and solder termination for MMCX connectors?

A: The 135-3302-401 supports both crimp and solder termination methods, offering assembly flexibility. The 262120 is configured for solder termination only. Crimp termination typically provides faster assembly without heat exposure, while solder termination creates a permanent connection. Selection depends on manufacturing process requirements and cable assembly specifications.

Q: Are there cable compatibility differences between these connectors?

A: The 135-3302-401 supports RG-178 and RG-196 cable groups. The 262120 supports an expanded cable group list including RG-178, 178A, 178B, 196, 196A, and M17/93-RG178. Both connectors are compatible with standard MMCX cable assemblies within their specified groups.

Q: What does ROHS3 compliance mean compared to RoHS compliance?

A: ROHS3 represents the current iteration of the Restriction of Hazardous Substances directive, incorporating updated restrictions on hazardous materials. Both certifications indicate the connector meets environmental and safety standards for electronic components. ROHS3 compliance indicates the part meets the most current regulatory requirements.

Q: Does packaging format affect connector performance?

A: No. The 135-3302-401 is supplied in bulk packaging while the 262120 uses bag packaging. Packaging format is a logistics consideration only and does not affect electrical performance, mechanical compatibility, or reliability characteristics.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both connectors carry this rating, meaning they can be stored and handled under standard conditions without special humidity or temperature controls prior to assembly.
