Pomona Electronics 73038 MMCX Connector Plug Equivalent & Substitute Parts

Part Overview

The Pomona Electronics 73038 is an MMCX connector plug designed for 50-ohm RF applications with through-hole solder termination. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The connector operates across a frequency range up to 6 GHz and is suitable for PCB-mounted applications requiring snap-on fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Pomona Electronics 73038 are qualified based on strict parameter matching across the following critical specifications:

Core Electrical Parameters: Impedance (50 Ohms), frequency capability (6 GHz maximum), and voltage rating (170 V) must be identical.

Mechanical Parameters: Connector style (MMCX), connector type (Plug, Male Pin), mounting type (Through Hole), and fastening type (Snap-On) must match exactly.

Termination Parameters: Both contact termination and shield termination must be solder-based.

Material and Finish Specifications: Body material (Brass), body finish (Gold), center contact plating (Gold), and dielectric material (PTFE) must be consistent.

Compliance Requirements: All substitute parts must maintain ROHS3 compliance and EAR99 ECCN classification.

The three qualified substitute parts—Cinch Connectivity Solutions 135-3801-201, Molex 0734152121, and Amphenol RF 262114—satisfy all these parameters and are suitable for direct replacement in applications requiring the Pomona 73038.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products from established manufacturers and provide direct functional equivalence to the obsolete Pomona 73038. Selection among these alternatives should be based on availability, packaging format, and supply chain considerations.

Cinch Connectivity Solutions 135-3801-201 is available in bulk packaging with 4,225 units in stock. This part carries REACH Affected status and MSL rating of 1 (Unlimited), indicating suitability for standard storage and handling conditions.

Molex 0734152121 is supplied in bag packaging with the highest inventory level of 35,951 units. This part is designated as series 73415 and carries REACH Affected status with MSL rating of 1 (Unlimited).

Amphenol RF 262114 is available in bag packaging with 913 units in stock. This part carries REACH Affected status with MSL rating of 1 (Unlimited). Operating temperature range is not specified for this variant.

All three parts maintain ROHS3 compliance and EAR99 classification, ensuring regulatory consistency with the original Pomona component.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 135-3801-201 directly replace the Pomona 73038?

A: Yes. Both parts share identical electrical specifications (50 Ohms, 6 GHz maximum frequency, 170 V rating), mechanical configuration (MMCX plug, through-hole solder termination, snap-on fastening), and material composition (brass body with gold finish, PTFE dielectric). The primary difference is product status: the Pomona is obsolete while the Cinch is active.

Q: What is the difference between the Molex 0734152121 and Amphenol RF 262114?

A: Both parts meet all core substitution parameters. The Molex variant specifies an operating temperature range of -55°C to 165°C, while the Amphenol RF part does not provide operating temperature specification. The Molex part has significantly higher inventory availability (35,951 units versus 913 units).

Q: Are there differences in center contact material among the substitutes?

A: Yes. The Pomona 73038 uses phosphor bronze for the center contact, while the Cinch 135-3801-201 uses beryllium copper. The Molex 0734152121 and Amphenol RF 262114 both use brass. These material variations do not affect the core electrical or mechanical substitution criteria for 50-ohm RF applications at 6 GHz.

Q: What packaging formats are available?

A: The Cinch 135-3801-201 is supplied in bulk packaging. Both the Molex 0734152121 and Amphenol RF 262114 are supplied in bag packaging. Packaging selection should align with procurement and assembly requirements.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. All three substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the original Pomona 73038. The substitute parts are designated as REACH Affected, whereas the original part is REACH Unaffected.

Q: What is the MSL rating for these connectors?

A: All three substitute parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The original Pomona part lists MSL as Not Applicable.
