APH-SMAP-MMCXJ Equivalent & Substitute Parts

Part Overview

The APH-SMAP-MMCXJ is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Plug (male pin) and MMCX Jack (female socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 6 GHz and supports an operating temperature range of -65°C to 165°C.

The APH-SMAP-MMCXJ is classified as obsolete. Equivalent substitute parts are available from active product lines, making substitution necessary for new procurement and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APH-SMAP-MMCXJ are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Adapter Type: Plug to Jack
• Adapter Series: SMA to MMCX
• Center Gender: Female to Male
• Convert From: SMA Plug, Male Pin
• Convert To: MMCX Jack, Female Socket
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On, Threaded
• Frequency - Max: 6 GHz
• Center Contact Plating: Gold
• Center Contact Material: Beryllium Copper
• Dielectric Material: PTFE

All substitute parts listed meet these mandatory parameters. Variations in body material, operating temperature range, mating cycles, and compliance certifications are noted in the parameter comparison table and do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 242140 (Amphenol RF)

The 242140 is the recommended substitute for the APH-SMAP-MMCXJ. Both parts are manufactured by Amphenol RF and share identical electrical and mechanical specifications. The 242140 is classified as an active product with ROHS3 compliance and REACH affected status, providing long-term availability and regulatory support. The operating temperature range (-65°C ~ 165°C) matches the original specification exactly. This part is available in bag packaging.

Alternative Substitute: HRMP-MMCXJ (Hirose Electric)

The HRMP-MMCXJ is a functionally equivalent substitute manufactured by Hirose Electric Co Ltd. This part meets all mandatory electrical and mechanical parameters. Key differences include body material (stainless steel versus brass), a narrower operating temperature range (-55°C ~ 85°C), and documented mating cycle rating of 500 cycles. The HRMP-MMCXJ is classified as active with ROHS3 compliance and REACH affected status. This part is available in bulk packaging.

Selection Criteria:

• For applications requiring the full original operating temperature range (-65°C ~ 165°C), select 242140.
• For applications operating within -55°C ~ 85°C with preference for stainless steel construction and documented mating cycle specifications, HRMP-MMCXJ is suitable.
• Both substitutes maintain 50 Ohm impedance, 6 GHz frequency rating, and identical connector configurations.

Frequently Asked Questions (FAQ)

Q: Can the 242140 directly replace the APH-SMAP-MMCXJ?

A: Yes. The 242140 is a direct functional equivalent with identical electrical specifications (50 Ohms, 6 GHz maximum frequency), connector configuration (SMA Plug to MMCX Jack), and operating temperature range (-65°C ~ 165°C). Both are manufactured by Amphenol RF.

Q: What is the primary difference between the 242140 and HRMP-MMCXJ?

A: The 242140 and HRMP-MMCXJ differ in body material (brass versus stainless steel), operating temperature range (-65°C ~ 165°C versus -55°C ~ 85°C), and mating cycle specification (not specified versus 500 cycles). Both maintain identical RF performance and connector configuration.

Q: Is the HRMP-MMCXJ suitable for my application if it operates at -60°C?

A: No. The HRMP-MMCXJ has a minimum operating temperature of -55°C. For applications requiring operation at -60°C, the 242140 is required, as it supports -65°C minimum temperature.

Q: Are there packaging differences between the substitute parts?

A: Yes. The 242140 is supplied in bag packaging, while the HRMP-MMCXJ is supplied in bulk packaging. The APH-SMAP-MMCXJ packaging is not specified. Select based on your procurement and handling requirements.

Q: Do all three parts have the same impedance and frequency rating?

A: Yes. The APH-SMAP-MMCXJ, 242140, and HRMP-MMCXJ all operate at 50 Ohms impedance with a maximum frequency rating of 6 GHz.

Q: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 compliance indicates adherence to the Restriction of Hazardous Substances Directive 3. Both substitute parts (242140 and HRMP-MMCXJ) carry ROHS3 certification, ensuring compliance with current regulatory requirements. The original APH-SMAP-MMCXJ carries RoHS Compliant status.

Q: Can I use these adapters interchangeably in the same system?

A: Yes, provided your application operates within the overlapping temperature range (-55°C ~ 85°C) and does not exceed the documented mating cycle limits. For applications requiring the full -65°C ~ 165°C range, use only the 242140.

Q: Are moisture sensitivity considerations the same across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
