MS-156NB(02) Equivalent & Substitute Parts

Part Overview

The MS-156NB(02) is a coaxial switch receptacle connector manufactured by Hirose Electric Co Ltd, designed for 50 Ohm RF applications with a 4mm plug diameter. This surface mount component features an internal switch mechanism with a snap-on fastening type and operates across -40°C to 85°C. The MS-156NB(02) is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS-156NB(02) is determined by the following critical parameters that must remain constant:

• Connector style: Coaxial Switch - 4mm Plug Dia
• Connector type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Mounting type: Surface Mount
• Contact termination: Solder
• Shield termination: Solder
• Fastening type: Snap-On
• Operating temperature range: -40°C ~ 85°C
• Mating cycles: 100
• Number of ports: 1

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent (MS-156HF(02)): Active status replacement with identical electrical and mechanical specifications except for dielectric material variant and insertion loss tolerance.

Manufacturer Recommended Substitutes (MS-156C, MS-156C(20)): Active status parts with enhanced frequency capability (11 GHz vs 6 GHz) and different contact material composition, maintaining all core mechanical and thermal parameters.

Parametric Equivalent (MS-156HF(22)): Active status part with matching electrical performance and mechanical interface, differing in dielectric material specification.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with active product status: MS-156HF(02) is the primary equivalent, offering identical mechanical and electrical interface compatibility with the obsolete MS-156NB(02). Both parts maintain 6 GHz maximum frequency and 50 Ohm impedance. MS-156HF(02) carries RoHS Compliant certification and is available in Tape & Reel packaging for automated assembly.

For applications requiring enhanced frequency performance: MS-156C and MS-156C(20) extend maximum frequency to 11 GHz while maintaining all core mechanical parameters and 50 Ohm impedance. These parts are manufacturer recommended substitutes with RoHS Compliant status. The increased insertion loss (0.4dB vs 0.1dB) must be evaluated against application requirements.

For parametric equivalence with active status: MS-156HF(22) provides matching electrical performance to MS-156HF(02) with identical 6 GHz frequency and insertion loss characteristics, suitable for applications where the dielectric material variant is acceptable.

All substitute parts maintain the same operating temperature range (-40°C ~ 85°C), mating cycle rating (100), and surface mount solder termination as the original MS-156NB(02).

Frequently Asked Questions (FAQ)

Q: Can MS-156HF(02) be used as a direct replacement for MS-156NB(02)?

A: Yes. MS-156HF(02) maintains identical connector style, impedance, mounting type, contact termination, and operating temperature specifications. The primary difference is active product status and RoHS compliance certification. Insertion loss tolerance differs slightly (0.15dB vs 0.1dB) and dielectric material uses Nylon 6T instead of Nylon 9T.

Q: What is the difference between MS-156C and MS-156HF series substitutes?

A: MS-156C series extends maximum frequency to 11 GHz compared to 6 GHz for MS-156HF series. MS-156C uses Copper Alloy center contact material versus Beryllium Copper in MS-156HF. Both maintain 50 Ohm impedance and identical mechanical interfaces. MS-156C insertion loss is 0.4dB versus 0.15dB for MS-156HF(02).

Q: Are all substitute parts RoHS compliant?

A: Yes. MS-156HF(02), MS-156C, MS-156C(20), and MS-156HF(22) are all RoHS Compliant. The original MS-156NB(02) RoHS status is not specified in the product data.

Q: What packaging options are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly. The original MS-156NB(02) packaging specification is not provided.

Q: Can MS-156C be used in applications designed for MS-156NB(02)?

A: MS-156C is mechanically and electrically compatible for the core 50 Ohm, 4mm coaxial switch interface. The 11 GHz frequency capability exceeds the original 6 GHz specification. Insertion loss increases to 0.4dB. Applications operating below 6 GHz with insertion loss budgets accommodating 0.4dB can use MS-156C as a substitute.

Q: What is the inventory status of substitute parts?

A: MS-156HF(02) has 722 units in stock, MS-156C has 6553 units, MS-156C(20) has 6966 units, and MS-156HF(22) has 1752 units available as new original stock.
